Sumatra island has in the margin of southwest part of the Eurasia plate in the Sundaland cratonic block and occurred as the amalgamation of allochtonous microplates, continental fragments, Island arc and accrctionary by foreland complex which assembled prior to Tertiary. The allochtonous rocks (terranes), can be divided into 4 (four) Terranes with Paleozoic to Mesosoic in age, had different origin, lithology and are separated by a Suture as main fault with trending NW-SE. The terranes are: the Tigapuluh-Bohorok (East Sumatra block / Sibumasu block), Permo-Carboniferous in age and is characterized by the rock types formed in glacio-marine and was intruded by Late Triassic to Early Jurrasic granitics, occupied in the Eastern part of Sumatra, the paleomagnetic data shown 41° South. Tanjung Karang - Gunung Kasih Terrane, is composed of higher metamorphic rocks and supposed to be pre-Carboniferous in age, covered by Mesozoic sedimentary rocks and were intruded by granitic-dioritic rocks, occupied in the Southern part of Sumatra, the paleomagnetic data shown 19° North. The Kuantan-Duabelas Mountain (West Sumatra block) is occupied by metamorphic, sedimentary and volcanic rocks of Paleozoic - Mesozoic (Carboniferous - Triassic) in age, contains a Cathaysion fauna and flora and are intruded by the Mesozoic granitoid rocks. The terrane occurred in the western part of Sumatra. Meanwhile, the Gumai-Garba (Waloya Terrane) which is occupied by the tectonite/melange, metasediment, carbonate and volcanic rocks of Mesozoic (Jurassic - Cretaceous) in age, are intruted by the Late Cretaceous granitoid rocks, the paleomagnetic data shown 30° - 31° South. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tectonostratigraphy" title="tectonostratigraphy">tectonostratigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=amalgamation" title=" amalgamation"> amalgamation</a>, <a href="https://publications.waset.org/abstracts/search?q=allochtonous" title=" allochtonous"> allochtonous</a>, <a href="https://publications.waset.org/abstracts/search?q=terranes" title=" terranes"> terranes</a>, <a href="https://publications.waset.org/abstracts/search?q=sumatra" title=" sumatra"> sumatra</a> </p> <a href="https://publications.waset.org/abstracts/43767/tectonostratigraphic-paleogeography-and-amalgamation-of-sumatra-terranes-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43767.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> The Effect of Sumatra Fault Earthquakes on West Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noushin%20Naraghi%20Araghi">Noushin Naraghi Araghi</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Nawawi"> M.

PGA is calculated by a probabilistic seismic hazard assessment (PSHA). A uniform catalog of earthquakes for the interest region has been provided. We used empirical relations to convert all magnitudes to Moment Magnitude. After eliminating foreshocks and aftershocks in order to achieve more reliable results, the completeness of the catalog and uncertainty of magnitudes have been estimated and seismicity parameters were calculated. Our seismic source model considers the Sumatran strike slip fault that is known historically to generate large earthquakes. The calculations were done using the logic tree method and four attenuation relationships and slip rates for different part of this fault. Seismic hazard assessment carried out for 48 grid points. Eventually, two seismic hazard maps based PGA for 5% and 10% probability of exceedance in 50 year are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumatra%20fault" title="Sumatra fault">Sumatra fault</a>, <a href="https://publications.waset.org/abstracts/search?q=west%20Malaysia" title=" west Malaysia"> west Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=PGA" title=" PGA"> PGA</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20parameters" title=" seismic parameters"> seismic parameters</a> </p> <a href="https://publications.waset.org/abstracts/9606/the-effect-of-sumatra-fault-earthquakes-on-west-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9606.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Legal Pluralism and Land Administration in West Sumatra: The Implementation of the Regulations of Both Local and Nagari Governments on Communal Land Tenure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilaire%20Tegnan">Hilaire Tegnan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Land administration has always been a delicate issue in the history of nations, and Indonesia, a country where a significant number of the population lives a pastoral life is not exempt from this reality. This paper discusses land tenure issues in West Sumatra, an Indonesian province which is home to the Minangkabau people with their long existing village management system known as Nagari, established to settle disputes based on adat (custom) principles as well as to protect the rights of the community members. These rights include communal land (referred to as tanahulayat hereafter). Long before the Dutch occupation of Indonesian archipelago, the nagari government was vested with powers to regulate communal land in West Sumatra. However, this authority was constantly overlooked by the then Dutch colonial administration as well as the post-independence governments (both central and regional). To reinforce the Nagari government as the guardian of the customary law (hukumadat) and to specify its jurisdiction, the Regional Government of West Sumatra enacted two laws between 2000 and 2008: Law No. 9/2000 repealed by Law No. 2/2007 and Law No. 6/2008 on communal land tenure. Although these two laws provide legal grounds to address land issues across the region, land conflicts still prevail among West Sumatran populations due to unsynchronized and contradictory regulations. The protests against the army (Korem) in Nagari Kapalo Hilalang, against the oil palm company in Nagari Kinali, and against a cement factory in Nagari Lubuk Kilangan are cited in this paper as case references. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=local%20government" title="local government">local government</a>, <a href="https://publications.waset.org/abstracts/search?q=Nagari%20government" title=" Nagari government"> Nagari government</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanah%20Ulayat" title=" Tanah Ulayat"> Tanah Ulayat</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20pluralism" title=" legal pluralism"> legal pluralism</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20administration" title=" land administration"> land administration</a> </p> <a href="https://publications.waset.org/abstracts/19953/legal-pluralism-and-land-administration-in-west-sumatra-the-implementation-of-the-regulations-of-both-local-and-nagari-governments-on-communal-land-tenure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">508</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Microbiological Quality and Safety of Meatball Sold in Payakumbuh City, West Sumatra, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferawati">Ferawati</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Purwanto"> H.

The overall corporation of technical programs was larger concern in stratigraphy, geochemical and age-dating studies. Availability of new data has been stimulated to reassessment of tectonic evolution of Sumatra Island. The study area located in Southern Sumatra within at latitudes 0°-6° S and 99°40’-106’00 E longitudes. The study tectonic is situated within along South Western margin of Sunda land, The Southeast Asia Continental extension arc of the Eurasian Plate and formed as part of Sunda Arc. The oceanic crust of Indian-Australian plate recently is being oblique subduction along the Sunda Trench off the West coast Sumatra. The Mesozoic-Cenozoic of the volcanic and granitic rocks can be divided into northern and southern plutons, defining a series subparallel, controlled by fault, northwest-southeast trending belts, some of the plutons are deformed and under-formed. They are widely exposed along the south-eastern side of the Barisan mountain. Based on the characteristic of minerals and crystallography, rocks found in this study area were granite, granitic, monzogranite and andesitic-Basaltic Volcanic Rock. It belongs to calc Alkaline was predominantly metalumina, I-Type Granite, Volcanic arc granites, Syncollisonal Granites (Syn_COLG) and tholeiitic basalt. It was formed since 169±5 to 20±1 Ma. The origin of magmas in interpreted to be derived from partial melting of igneous rock. The occurrence of the gratoid and volcanic rocks supposed to be closely related to the subduction of the Australian-Hindia oceanic crust beneath the Eurasia/Sunda land Continental Crust as Volcanic arc or continental margin granitic and shown youngest to the southwest. The subduction process having probably been different in position between one terrane to others led to the occurrence of segmentation subduction system. The positional discontinuities of the subduction are probably caused by the difference in time of emplacement and mechanism of volcanic and granitic rock between segments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tectonic%20setting" title="tectonic setting">tectonic setting</a>, <a href="https://publications.waset.org/abstracts/search?q=I-type%20granitic" title=" I-type granitic"> I-type granitic</a>, <a href="https://publications.waset.org/abstracts/search?q=subduction" title=" subduction"> subduction</a>, <a href="https://publications.waset.org/abstracts/search?q=Southern%20Sumatra" title=" Southern Sumatra"> Southern Sumatra</a> </p> <a href="https://publications.waset.org/abstracts/60668/the-geochemical-characteristic-and-tectonic-setting-of-mezoic-cenozoic-volcanic-and-granitic-rocks-in-southern-sumatra-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Reconstructing the Trace of Mesozoic Subduction and Its Implication on Stratigraphy Correlation between Deep Marine Sediment and Granite: Case Study of Garba Complex, South Sumatera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadlan%20Atmaja%20Nursiwan">Fadlan Atmaja Nursiwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugi%20Kurnia%20Gusti"> Ugi Kurnia Gusti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Garba Hill, located in Tekana Village, South Sumatera Province is comprised to South Sumatra Basin and classified as back arc basin.

Oil or crystals that containing borneol are harvested from the camphor tree (Dryobalanops aromatica). Non-timber forest products are utilized for the manufacture of fragrances, antiseptics, anti-inflammatory, analgesic as well as effective for the treatment of blocked arteries. Based on exploration on the west coast of Sumatra, these endemic tree species were found remaining growing in groups on small spots in the lowlands to the hills. Some populations are found at an altitude of 700 meters above sea level in Kadabuhan, Jongkong and Sultan Daulat in Subulussalam district, Singkohor and Lake Paris in Aceh Singkil district, and Sirandorung and Manduamas in the north of Barus, Central Tapanuli district. These multi-purpose tree species was also identified as being able to adapt to the Singkil Peat Swamp. The decline in tree population has a direct impact on reducing their productivity. Conventionally, the crystals are harvested by cutting and splitting the stem into wooden blocks. In this way about 1.5-2.5 kg of crystals are obtained with various qualities. Camphor retrieval can also be done by making a notch on a standing tree trunk and collecting liquid resin (ombil) that is removed from the injured resin channel. Twigs and leaves also contain borneol. The aromatic content in this section opens opportunities for the supply of borneol through the distillation process. Vegetative propagation technology is needed to overcome the limitations of available seeds. This breeding strategy for vulnerable species starts with gathering genetic material from various provenances which are then used to support the provision of basic populations, breeding populations, multiplication populations and production populations for extensive development of camphor tree plantations <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camphor" title="camphor">camphor</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20borneol" title=" natural borneol"> natural borneol</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerable%20species" title=" vulnerable species"> vulnerable species</a> </p> <a href="https://publications.waset.org/abstracts/120156/the-distribution-productivity-and-conservation-of-camphor-tree-dryobalanops-aromatica-in-west-coast-of-sumatra-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120156.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Comparisons of Co-Seismic Gravity Changes between GRACE Observations and the Predictions from the Finite-Fault Models for the 2012 Mw = 8.6 Indian Ocean Earthquake Off-Sumatra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armin%20Rahimi">Armin Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Gravity Recovery and Climate Experiment (GRACE) has been a very successful project in determining math redistribution within the Earth system. Large deformations caused by earthquakes are in the high frequency band. Unfortunately, GRACE is only capable to provide reliable estimate at the low-to-medium frequency band for the gravitational changes. In this study, we computed the gravity changes after the 2012 Mw8.6 Indian Ocean earthquake off-Sumatra using the GRACE Level-2 monthly spherical harmonic (SH) solutions released by the University of Texas Center for Space Research (UTCSR). Moreover, we calculated gravity changes using different fault models derived from teleseismic data. The model predictions showed non-negligible discrepancies in gravity changes. However, after removing high-frequency signals, using Gaussian filtering 350 km commensurable GRACE spatial resolution, the discrepancies vanished, and the spatial patterns of total gravity changes predicted from all slip models became similar at the spatial resolution attainable by GRACE observations, and predicted-gravity changes were consistent with the GRACE-detected gravity changes. Nevertheless, the fault models, in which give different slip amplitudes, proportionally lead to different amplitude in the predicted gravity changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=undersea%20earthquake" title="undersea earthquake">undersea earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=GRACE%20observation" title=" GRACE observation"> GRACE observation</a>, <a href="https://publications.waset.org/abstracts/search?q=gravity%20change" title=" gravity change"> gravity change</a>, <a href="https://publications.waset.org/abstracts/search?q=dislocation%20model" title=" dislocation model"> dislocation model</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20distribution" title=" slip distribution"> slip distribution</a> </p> <a href="https://publications.waset.org/abstracts/69152/comparisons-of-co-seismic-gravity-changes-between-grace-observations-and-the-predictions-from-the-finite-fault-models-for-the-2012-mw-86-indian-ocean-earthquake-off-sumatra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69152.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">355</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Risk-Based Institutional Evaluation of Trans Sumatera Toll Road Infrastructure Development to Improve Time Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ridho%20Fakhrin">Muhammad Ridho Fakhrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Leni%20Sagita%20Riantini"> Leni Sagita Riantini</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Latief"> Yusuf Latief</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on the 2015-2019 RPJMN data, the realization of toll road infrastructure development in Indonesia experienced a delay of 49% or 904 km of the total plan.

Forest degradation enormous impact on global warming is a reality we have experienced together, that disruption of ecosystems, extreme weather conditions, disruption of water management system watersheds and the threat of natural disasters as floods, landslides and droughts, even disruption food security. Dharmasraya is a district in the province of West Sumatra, which has an area of 92.150 ha of forest, which is largely a former production forest concessions (Forest Management Rights) which is supposed to be a secondary forest. This study answers about the impact of land use in the former concession area Dharmasraya on the environment. The methodology used is the household survey, key informants, and satellite data / GIS. From the results of the study, the former concession area in Dharmasraya experienced a reduction of forest cover over time significantly. Forest concessions should be secondary forests in Dharmasraya, now turned conversion to oil palm plantations. Population pressures and growing economic pressures, resulting in more intensive harvesting. As a result of these forest disturbances caused changes in forest functions. These changes put more emphasis towards economic function by ignoring social functions or ecological function. Society prefers to maximize their benefits today and pay less attention to the protection of natural resources. This causes global warming is increasing and this is not only felt by people around Dharmasraya but also the world. Land clearing by the community through a process in slash and burn. This fire was observed by NOAA satellites and recorded by the Forest Service of West Sumatra. This demonstrates the ability of trees felled trees to absorb carbon dioxide (CO2) to be lost, even with forest fires accounted for carbon dioxide emitted into the air, and this has an impact on global warming. In addition to the change of control of land into oil palm plantations water service has been poor, people began to trouble the water and oil palm plantations are located in the watershed caused the river dried up. Through the findings of this study is expected to contribute ideas to the policy makers to pay more attention to the former concession forest management as the prevention or reduction of global warming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=community" title=" community"> community</a>, <a href="https://publications.waset.org/abstracts/search?q=concession%20forests" title=" concession forests"> concession forests</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/27729/the-impact-of-land-use-ex-concession-to-the-environment-in-dharmasraya-district-west-sumatra-province-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27729.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Physical Properties of Rice Field Receiving Irrigation Polluted by Gold Mine Tailing: Case Study in Dharmasraya, West Sumatra, Indonesia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yulna%20Yulnafatmawita">Yulna Yulnafatmawita</a>, <a href="https://publications.waset.org/abstracts/search?q=Syafrimen%20Yasin"> Syafrimen Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lusi%20Maira"> Lusi Maira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Irrigation source is one of the factors affecting physical properties of rice field. This research was aimed to determine the impact of polluted irrigation wáter on soil physical properties of rice field. The study site was located in Koto Nan IV, Dharmasraya Regency, West Sumatra, Indonesia. The rice field was irrigated with wáter from Momongan river in which people do gold mining. The soil was sampled vertically from the top to 100 cm depth with 20 cm increment of soil profile from 2 year-fallowed rice field, as well as from the top 20 cm of cultivated rice field from the terrace-1 (the highest terrace) to terrace-5 (the lowest terrace) position. Soil samples were analysed in laboratory. For comparison, rice field receiving irrigation wáter from non-polluted source was also sampled at the top 20 cm and anaysed for the physical properties. The result showed that there was a change in soil physical properties of rice field after 9 years of getting irrigation from the river. Based on laboratory analyses, the total suspended solid (TSS) in the tailing reached 10,736 mg/L. The texture of rice field at polluted rice field (PRF) was dominated (>55%) by sand particles at the top 100 cm soil depth, and it tended to linearly decrease (R2=0.65) from the top 20 cm to 100 cm depth. Likewise, the sand particles also linearly decreased (R2=0.83), but clay particles linearly increased (R2=0.74) horizontally as the distance from the wáter input (terrace-1) was fartherst. Compared to nonpolluted rice field (NPRF), percentage of sand was higher, and clay was lower at PRF. This sandy texture of soil in PRF increased soil hydraulic conductivity (up to 19.1 times), soil bulk density (by 38%), and sharply decreased SOM (by 88.5 %), as well as soil total pore (by 22.1%) compared to the NPRF at the top 20 cm soil. The rice field was suggested to be reclaimed before reusing it. Otherwise the soil characteristics requirement, especially soil wáter retention, for rice field could not be fulfilled. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20mine%20tailing" title="gold mine tailing">gold mine tailing</a>, <a href="https://publications.waset.org/abstracts/search?q=polluted%20irrigation" title=" polluted irrigation"> polluted irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20field" title=" rice field"> rice field</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20physical%20properties" title=" soil physical properties"> soil physical properties</a> </p> <a href="https://publications.waset.org/abstracts/63006/physical-properties-of-rice-field-receiving-irrigation-polluted-by-gold-mine-tailing-case-study-in-dharmasraya-west-sumatra-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> The Development of the Geological Structure of the Bengkulu Fore Arc Basin, Western Edge of Sundaland, Sumatra, and Its Relationship to Hydrocarbon Trapping Mechanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lauti%20Dwita%20Santy">Lauti Dwita Santy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hermes%20Panggabean"> Hermes Panggabean</a>, <a href="https://publications.waset.org/abstracts/search?q=Syahrir%20Andi%20Mangga"> Syahrir Andi Mangga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Bengkulu Basin is part of the Sunda Arc system, which is a classic convergent type margin that occur around the southern rim of the Eurasian continental (Sundaland) plate. The basin is located between deep sea trench (Mentawai Outer Arc high) and the volvanic/ magmatic Arc of the Barisan Mountains Range. To the northwest it is bounded by Padang High, to the northest by Barisan Mountains (Sumatra Fault Zone) to the southwest by Mentawai Fault Zone and to the southeast by Semangko High/ Sunda Strait. The stratigraphic succession and tectonic development can be broadly divided into four stage/ periods, i.e Late Jurassic- Early Cretaceous, Late Eocene-Early Oligocene, Late Oligocene-Early Miocene, Middle Miocene-Late Miocene and Pliocene-Plistocene, which are mainly controlled by the development of subduction activities. The Pre Tertiary Basement consist of sedimentary and shallow water limestone, calcareous mudstone, cherts and tholeiitic volcanic rocks, with Late Jurassic to Early Cretaceous in age. The sedimentation in this basin is depend on the relief of the Pre Tertiary Basement (Woyla Terrane) and occured into two stages, i.e. transgressive stage during the Latest Oligocene-Early Middle Miocene Seblat Formation, and the regressive stage during the Latest Middle Miocene-Pleistocene (Lemau, Simpangaur and Bintunan Formations). The Pre-Tertiary Faults were more intensive than the overlying cover, The Tertiary Rocks. There are two main fault trends can be distinguished, Northwest–Southwest Faults and Northeast-Southwest Faults. The NW-SE fault (Ketaun) are commonly laterally persistent, are interpreted to the part of Sumatran Fault Systems. They commonly form the boundaries to the Pre Tertiary basement highs and therefore are one of the faults elements controlling the geometry and development of the Tertiary sedimentary basins.The Northeast-Southwest faults was formed a conjugate set to the Northwest–Southeast Faults. In the earliest Tertiary and reactivated during the Plio-Pleistocene in a compressive mode with subsequent dextral displacement. The Block Faulting accross these two sets of faults related to approximate North–South compression in Paleogene time and produced a series of elongate basins separated by basement highs in the backarc and forearc region. The Bengkulu basin is interpreted having evolved from pull apart feature in the area southwest of the main Sumatra Fault System related to NW-SE trending in dextral shear.Based on Pyrolysis Yield (PY) vs Total Organic Carbon (TOC) diagram show that Seblat and Lemau Formation belongs to oil and Gas Prone with the quality of the source rocks includes into excellent and good (Lemau Formation), Fair and Poor (Seblat Formation). The fine-grained carbonaceous sediment of the Seblat dan Lemau Formations as source rocks, the coarse grained and carbonate sediments of the Seblat and Lemau Formations as reservoir rocks, claystone bed in Seblat and Lemau Formation as caprock.

It started to identify petroleum concept in the basin. The main objectives of this paper are to integrate and develop information, knowledge, and evaluation from Indonesia’s sedimentary basins system in terms of their suitability for exploration activity and estimate the hydrocarbon potential available. The system which compiled data information and knowledge and comprised exploration and production data of all basins in Indonesia called as Basin Professor which stands for Basin Professional and Processor. Basin Professor is a website application using Geography Information System which consists of all information about basin montage, basin summary, petroleum system, stratigraphy, development play, risk factor, exploration history, working area, regional cross section, well correlation, prospect & lead inventory and infrastructure spatial. From 82 identified sedimentary basins, North Sumatra, Central Sumatra, South Sumatera, East Java, Kutai, and Tarakan basins are respectively positioned of the Indonesia’ s mature basin and the most productive basin. The Eastern of Indonesia also have many hydrocarbon potential and discovered several fields in Papua and East Abadi. Basin Professor compiled the well data in all of the basin in Indonesia from mature basin to frontier basin. Well known geological data, subsurface mapping, prospect and lead, resources and established infrastructures are the main factors make these basins have higher suitability beside another potential basin. The hydrocarbon potential resulted from this paper based on the degree of geological data, petroleum, and economic evaluation. Basin Professor has provided by a calculator tool in lead and prospect for estimate the hydrocarbon reserves, recoverable in place and geological risk. Furthermore, the calculator also defines the preliminary economic evaluation such as investment, POT IRR and infrastructures in each basin. From this Basin Professor, petroleum companies are able to estimate that Indonesia has a huge potential of hydrocarbon oil and gas reservoirs and still interesting for hydrocarbon exploration and production activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basin%20summary" title="basin summary">basin summary</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20system" title=" petroleum system"> petroleum system</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20evaluation" title=" economic evaluation"> economic evaluation</a> </p> <a href="https://publications.waset.org/abstracts/62961/basin-professor-petroleum-geology-assessor-in-indonesia-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Local Religion 'Parmalim': Between Civilization and Faith</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabrina%20Yulianti">Sabrina Yulianti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to explain the identity struggles of local religious communities in Indonesia.

Alsintan used to change the traditional farming systems generally use manual equipment into modern agriculture with mechanization. CV Nugraha Chakti Consultant make an action plan for industrial development Alsintan West Sumatra in 2012 to develop medium industries of Alsintan become a major industry of Alsintan, one of efforts made is increase the production capacity of the industry Alsintan. Production capacity for superior products as hydrotiller and threshers set each for 2.000 units per year. CV Citra Dragon as one of the medium industry alsintan in West Sumatra has a plan to relocate the existing plant to meet growing consumer demand each year. Increased production capacity and plant relocation plan has led to a change in the layout; therefore need to design the layout of the plant facility CV Citra Dragon. First step the to design of plant layout is design the layout of the production floor. The design of the production floor layout is done by applying group technology layout. The initial step is to do a machine grouping and part family using the Average Linkage Clustering (ALC) and Rank Order Clustering (ROC). Furthermore done independent work station design and layout design using the Modified Spanning Tree (MST). Alternative selection layout is done to select the best production floor layout between ALC and ROC cell grouping. Furthermore, to design the layout of warehouses, offices and other production support facilities. Activity Relationship Chart methods used to organize the placement of factory facilities has been designed. After structuring plan facilities, calculated cost manufacturing facility plant establishment. Type of layout is used on the production floor layout technology group. The production floor is composed of four cell machinery, assembly area and painting area. The total distance of the displacement of material in a single production amounted to 1120.16 m which means need 18,7minutes of transportation time for one time production. Alsintan Factory has designed a circular flow pattern with 11 facilities. The facilities were designed consisting of 10 rooms and 1 parking space. The measure of factory building is 84 m x 52 m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Average%20Linkage%20Clustering%20%28ALC%29" title="Average Linkage Clustering (ALC)">Average Linkage Clustering (ALC)</a>, <a href="https://publications.waset.org/abstracts/search?q=Rank%20Order%20Clustering%20%28ROC%29" title=" Rank Order Clustering (ROC)"> Rank Order Clustering (ROC)</a>, <a href="https://publications.waset.org/abstracts/search?q=Modified%20Spanning%20Tree%20%28MST%29" title=" Modified Spanning Tree (MST)"> Modified Spanning Tree (MST)</a>, <a href="https://publications.waset.org/abstracts/search?q=Activity%20Relationship%20Chart%20%28ARC%29" title=" Activity Relationship Chart (ARC)"> Activity Relationship Chart (ARC)</a> </p> <a href="https://publications.waset.org/abstracts/22511/design-of-agricultural-machinery-factory-facility-layout" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22511.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">496</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> State Forest Management Practices by Indigenous Peoples in Dharmasraya District, West Sumatra Province, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Mutolib">Abdul Mutolib</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonariza%20Mahdi"> Yonariza Mahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanung%20Ismono"> Hanung Ismono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The existence of forests is essential to human lives on earth, but its existence is threatened by forest deforestations and degradations. Forest deforestations and degradations in Indonesia is not only caused by the illegal activity by the company or the like, even today many cases in Indonesia forest damage caused by human activities, one of which cut down forests for agriculture and plantations. In West Sumatra, community forest management are the result supported the enactment of customary land tenure, including ownership of land within the forest. Indigenous forest management have a positive benefit, which gives the community an opportunity to get livelihood and income, but if forest management practices by indigenous peoples is not done wisely, then there is the destruction of forests and cause adverse effects on the environment. Based on intensive field works in Dhamasraya District employing some data collection techniques such as key informant interviews, household surveys, secondary data analysis, and satellite image interpretation. This paper answers the following questions; how the impact of forest management by local communities on forest conditions (foccus in Forest Production and Limited Production Forest) and knowledge of the local community on the benefits of forests. The site is a Nagari Bonjol, Dharmasraya District, because most of the forest in Dharmasraya located and owned by Nagari Bonjol community. The result shows that there is damage to forests in Dharmasraya because of forest management activities by local communities. Damage to the forest area of 33,500 ha in Dharmasraya because forests are converted into oil palm and rubber plantations with monocultures. As a result of the destruction of forests, water resources are also diminishing, and the community has experienced a drought in the dry season due to forest cut down and replaced by oil palm plantations. Knowledge of the local community on the benefits of low forest, the people considered that the forest does not have better benefits and cut down and converted into oil palm or rubber plantations. Local people do not understand the benefits of ecological and environmental services that forests. From the phenomena in Dharmasraya on land ownership, need to educate the local community about the importance of protecting the forest, and need a strategy to integrate forests management to keep the ecological functions that resemble the woods and counts the economic benefits for the welfare of local communities. One alternative that can be taken is to use forest management models agroforestry smallholders in accordance with the characteristics of the local community who still consider the economic, social and environmental. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=customary%20land" title=" customary land"> customary land</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer%20plantations" title=" farmer plantations"> farmer plantations</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20forests" title=" and forests"> and forests</a> </p> <a href="https://publications.waset.org/abstracts/27605/state-forest-management-practices-by-indigenous-peoples-in-dharmasraya-district-west-sumatra-province-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Ancient Malay and Spice Trade Routes: A Study of Ancient Malay from the Perspectives of Linguistics and Archaeology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Totok%20Suhardijanto">Totok Suhardijanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ninie%20Susanti%20Tedjowasono"> Ninie Susanti Tedjowasono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the relationship between the distribution of Ancient Malay inscriptions and Spice Trade Route, especially in the relation with material cultures that accompany them, to understand how Malay could spread out around the archipelago beyond its original native-speakers’ region. The archipelago was known as the Spice Islands from the very beginning of the first century due to mace, cloves, and nutmeg that were originally exclusively found there. According to the Indian record, since the 2nd century, there has been a contact established between Indian and Indonesian people. A Chinese document from 3rd Century has mentioned Wangka (now widely known as Bangka) an island near Sumatra where some Chinese expeditions had visited. All of these records supported the existence of a maritime trade system and route between the archipelago and other countries during the first millennium. This paper will discuss first the Ancient Malay inscription spread around the archipelago from the perspectives of language variation and writing system style. Analyzing language variations of inscriptions certainly is not as easy as studying current spoken language variations in modern sociolinguistics. A huge amount of data is available for such kind of studies. On the contrary, in language variation research with inscription texts as an object, data is insufficient. Other resources will be needed to support the linguistic analysis. For this reason, this research made use of epigraphical evidence in the surrounding areas of the inscriptions to explain the variation of language and writing style. The research next expands the analysis to figure out the relationship between language variation and inscriptions distribution to the Spice Trade Route that spreads from the Molucca Sea to Mediterranian Sea. Data in this research consists of six different inscriptions: Kedukan Bukit, Koto Kapur, Dapunta Salendra, Sang Hyang Wintang, Ligor, and Laguna from the 7th-9th Century and found in Sumatra, Jawa, and the Philippines. In addition, as a comparative resource, this research also used Hikayat Tanjung Tanah, the first-founded Ancient Malay manuscript. In language analysis, we conduct a sociolinguistic method to explore the language variation and writing style of the inscriptions. For dealing with archaeological data, we conducted a hermeneutic method to analyze the possible meaning and social uses of the data. Language variations and writing system style in this research can be classified into two main groups. The language, epigraphical, and archaeological evidence explain that Ancient Malay had been widely used in the Eastern area of Spice Trade Route because it played an important role in the region as a lingua franca between people from different ethnic groups with different languages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ancient%20Malay" title="Ancient Malay">Ancient Malay</a>, <a href="https://publications.waset.org/abstracts/search?q=Spice%20trade%20route" title=" Spice trade route"> Spice trade route</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20variation" title=" language variation"> language variation</a>, <a href="https://publications.waset.org/abstracts/search?q=writing%20system%20variation" title=" writing system variation"> writing system variation</a> </p> <a href="https://publications.waset.org/abstracts/80645/ancient-malay-and-spice-trade-routes-a-study-of-ancient-malay-from-the-perspectives-of-linguistics-and-archaeology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80645.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">193</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Story Telling Method as a Bastion of Local Wisdom in the Frame of Education Technology Development in Medan, North Sumatra-Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mardianto">Mardianto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Education and learning are now grown rapidly. Synergy of techonology especially instructional technology in the learning activities are very big influence on the effectiveness of learning and creativity to achieve optimal results. But on the other hand there is a education value that is difficult to be articulated through character-forming technology such as honesty, discipline, hard work, heroism, and so forth. Learning strategy and storytelling from the past until today is still an option for teachers to convey the message of character values. With the material was loaded from the local culture (stories folklore), the combination of learning objectives (build character child) strategy, and traditional methods (storytelling and story), and the preservation of local culture (dig tale folklore) is critical to maintaining the nation's culture. In the context of maintaining the nation's culture, then since the age of the child at the level of government elementary school a necessity. Globalization, the internet and technology sometimes feel can displace the role of the teacher in the learning activities. To the oral tradition is a mainstay of storytelling should be maintained and preserved. This research was conducted at the elementary school in the city of Medan, North Sumatra Indonesia, with a random sampling technique, the 27 class teachers were respondents who were randomly assigned to the Madrasah Ibtdaiyah (Islamic Elementary School) both public and private. Research conducted at the beginning of 2014 refers to a curriculum that is being transformed in the environment ministry Republic Religion Indonesia. The results of this study indicate that; the declining skills of teachers to develop storytelling this can be seen from; 74.07% of teachers have never attended a special training storytelling, 85.19% no longer nasakah new stories, only 22.22% are teachers who incorporate methods of stories in the learning plan. Most teachers are no longer concerned with storytelling, among those experiencing difficulty in developing methods because the story; 66.67% of children are more interested in children's cartoons like Bobo boy, Angrybirds and others, 59.26 children prefer other activities than listening to a story. The teachers hope, folklore books should be preserved, storytelling training should be provided by the government through the ministry of religion, race or competition of storytelling should be scheduled, writing a new script-based populist storytelling should be provided immediately. The teachers’ hope certainly not excessive, by realizing the story method becomes articulation as the efforts of child character development based populist, therefore the local knowledge can be a strong fortress facing society in the era of progress as at present, and future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=story%20telling" title="story telling">story telling</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20wisdom" title=" local wisdom"> local wisdom</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20development" title=" technology development"> technology development</a> </p> <a href="https://publications.waset.org/abstracts/29615/story-telling-method-as-a-bastion-of-local-wisdom-in-the-frame-of-education-technology-development-in-medan-north-sumatra-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29615.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Co-Seismic Deformation Using InSAR Sentinel-1A: Case Study of the 6.5 Mw Pidie Jaya, Aceh, Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jefriza">Jefriza</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibah%20Lateh"> Habibah Lateh</a>, <a href="https://publications.waset.org/abstracts/search?q=Saumi%20Syahreza"> Saumi Syahreza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 2016 Mw 6.5 Pidie Jaya earthquake is one of the biggest disasters that has occurred in Aceh within the last five years. This earthquake has caused severe damage to many infrastructures such as schools, hospitals, mosques, and houses in the district of Pidie Jaya and surrounding areas. Earthquakes commonly occur in Aceh Province due to the Aceh-Sumatra is located in the convergent boundaries of the Sunda Plate subducted beneath the Indo-Australian Plate. This convergence is responsible for the intensification of seismicity in this region. The plates are tilted at a speed of 63 mm per year and the right lateral component is accommodated by strike- slip faulting within Sumatra, mainly along the great Sumatran fault. This paper presents preliminary findings of InSAR study aimed at investigating the co-seismic surface deformation pattern in Pidie Jaya, Aceh-Indonesia. Coseismic surface deformation is rapid displacement that occurs at the time of an earthquake. Coseismic displacement mapping is required to study the behavior of seismic faults. InSAR is a powerful tool for measuring Earth surface deformation to a precision of a few centimetres. In this study, two radar images of the same area but at two different times are required to detect changes in the Earth’s surface. The ascending and descending Sentinel-1A (S1A) synthetic aperture radar (SAR) data and Sentinels application platform (SNAP) toolbox were used to generate SAR interferogram image. In order to visualize the InSAR interferometric, the S1A from both master (26 Nov 2016) and slave data-sets (26 Dec 2016) were utilized as the main data source for mapping the coseismic surface deformation. The results show that the fringes of phase difference have appeared in the border region as a result of the movement that was detected with interferometric technique. On the other hand, the dominant fringes pattern also appears near the coastal area, this is consistent with the field investigations two days after the earthquake. However, the study has also limitations of resolution and atmospheric artefacts in SAR interferograms. The atmospheric artefacts are caused by changes in the atmospheric refractive index of the medium, as a result, has limitation to produce coherence image. Low coherence will be affected the result in creating fringes (movement can be detected by fringes). The spatial resolution of the Sentinel satellite has not been sufficient for studying land surface deformation in this area. Further studies will also be investigated using both ALOS and TerraSAR-X. ALOS and TerraSAR-X improved the spatial resolution of SAR satellite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=InSAR" title=" InSAR"> InSAR</a>, <a href="https://publications.waset.org/abstracts/search?q=interferometric" title=" interferometric"> interferometric</a>, <a href="https://publications.waset.org/abstracts/search?q=Sentinel-1A" title=" Sentinel-1A"> Sentinel-1A</a> </p> <a href="https://publications.waset.org/abstracts/69671/co-seismic-deformation-using-insar-sentinel-1a-case-study-of-the-65-mw-pidie-jaya-aceh-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69671.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Experimental Investigation on Tsunami Acting on Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iman%20Mazinani">Iman Mazinani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zubaidah%20Ismail"> Zubaidah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Mustafa%20Hashim"> Ahmad Mustafa Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Saba"> Amir Reza Saba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two tragic tsunamis that devastated the west coast of Sumatra Island, Indonesia in 2004 and North East Japan in 2011 had damaged bridges to various extents. Tsunamis have resulted in the catastrophic deterioration of infrastructures i.e. coastal structures, utilities and transportation facilities. A bridge structure performs vital roles to enable people to perform activities related to their daily needs and for development. A damaged bridge needs to be repaired expeditiously. In order to understand the effects of tsunami forces on bridges, experimental tests are carried out to measure the characteristics of hydrodynamic force at various wave heights. Coastal bridge models designed at a 1:40 scale are used in a 24.0 m long hydraulic flume with a cross section of 1.5 m by 2.0 m. The horizontal forces and uplift forces in all cases show that forces increase nonlinearly with increasing wave amplitude. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tsunami" title="tsunami">tsunami</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge" title=" bridge"> bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20force" title=" horizontal force"> horizontal force</a>, <a href="https://publications.waset.org/abstracts/search?q=uplift%20force" title=" uplift force"> uplift force</a> </p> <a href="https://publications.waset.org/abstracts/14510/experimental-investigation-on-tsunami-acting-on-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Combination Urea and KCl with Powder Coal Sub-Bituminous to Increase Nutrient Content of Ultisols in Limau Manis Padang West Sumatra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amsar%20Maulana">Amsar Maulana</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafdea%20Syafitri"> Rafdea Syafitri</a>, <a href="https://publications.waset.org/abstracts/search?q=Topanal%20%20Gustiranda"> Topanal Gustiranda</a>, <a href="https://publications.waset.org/abstracts/search?q=Natasya%20Permatasari"> Natasya Permatasari</a>, <a href="https://publications.waset.org/abstracts/search?q=Herviyanti"> Herviyanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coal as an alternative source of humic material that has the potential of 973.92 million tons (sub-bituminous amounted to 673.70 million tons) in West Sumatera.

The objective of the study was to identify the impact of fire on bird diversity in oil palm plantations. Data of bird diversity were collected using the line transect method. Data were collected from February to March 2017. To estimate species richness, we used the Margalef index, to determine the evenness of species richness between site, we used an Evenness index, and to estimate the similarity of bird communities between different habitat, we used the Sørensen index. The result showed that the number of bird species and species richness in the post burned area was higher than those in unburned area. Different results were found for the Evenness Index, where the value was higher in unburned area that was in post burned area. These results indicate that fires did not decrease bird diversity as alleged by many parties whom stated that fires caused species extinction. Fire trigger the emerging of belowground plant and population of insects as a sources of food for the bird community. This result is consistent with several research findings in the United States and Australia that used controlled fires as one of regional management tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bird" title="bird">bird</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=index%20of%20similarity" title=" index of similarity"> index of similarity</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20palm" title=" oil palm"> oil palm</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20diversity" title=" species diversity"> species diversity</a> </p> <a href="https://publications.waset.org/abstracts/79626/impact-of-fire-on-bird-diversity-in-oil-palm-plantation-case-study-in-south-sumatra-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79626.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Correlation between Knowledge Level and Public Perception of Autopsy on Criminal Offence Victim in Pulau Punjung</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osalina%20Toemapa">Osalina Toemapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Rika%20Susanti"> Rika Susanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Husna%20Yetti"> Husna Yetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In criminal offense case, such as homicide, investigators may request for an autopsy to the victim without family approval in Indonesia. Generally, there has been decreasing in autopsy rate in the world over past years. Family’s refusal is one of the most common problems. The purpose of this study is to find the correlation between knowledge level and public perception of autopsy on criminal offense victim. This cross-sectional study was done from April to May 2017 in subdistrict Pulau Punjung. Participants were asked to fill the questionnaire. There are 15 questions to asses knowledge level, perception, and factors influencing autopsy refusal. The chi-square test was used for the statistical analysis. Out of the total of 436 respondents, 54,5% were found to have poor knowledge level, and 56,7% were found to have poor perception. There was a significant correlation between knowledge level and public perception (p<0,001). There are 153 respondents who decline autopsy on criminal offense victim with the most factors influencing autopsy refusal is delays in victim’s funeral (92,2%). Conclusion, knowledge level is correlated with public perception in subdistrict of Pulau Punjung, district of Dharmasraya, West Sumatra, Indonesia. Most influencing factor in autopsy refusal is delays in victim’s funeral. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20level" title="knowledge level">knowledge level</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20perception" title=" public perception"> public perception</a>, <a href="https://publications.waset.org/abstracts/search?q=autopsy%20on%20criminal%20offense%20victim" title=" autopsy on criminal offense victim"> autopsy on criminal offense victim</a>, <a href="https://publications.waset.org/abstracts/search?q=autopsy%20refusal" title=" autopsy refusal"> autopsy refusal</a> </p> <a href="https://publications.waset.org/abstracts/83320/correlation-between-knowledge-level-and-public-perception-of-autopsy-on-criminal-offence-victim-in-pulau-punjung" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83320.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Combined Aplication of Indigenous Pseudomonas fluorescens and the AM Fungi as the Potential Biocontrol Agents of Banana Fusarium wilt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eri%20Sulyanti">Eri Sulyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Trimurti%20Habazar"> Trimurti Habazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Eti%20Farda%20Husen"> Eti Farda Husen</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdi%20Dharma"> Abdi Dharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasril%20Nasir"> Nasril Nasir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, combination of some biocontrol agents with different mechanisms was an alternative to improve the effectiveness of the biological control agents. Single and combined applications of indigenous Pseudomonas fluorescens and Arbuscular Mychorrhizae Fungi (AM Fungi) isolates were tested to induce the resistance on susceptible Cavendish banana against F.oxysporum f. sp. cubense race 4 under greenhouse conditions. These isolates originally isolated from healthy banana rhizosphere at endemic Fusarium wilt areas in the centre of production banana in West Sumatra. These researches were conducted with Randomized Block Design with 16 treatments and 10 replications. The treatments were three indigenous isolates of Pseudomonas fluorescens (Par1-Cv, Par4-Rj1, Par2-Jt1) and 3 isolates of AM Fungi (Gl1BuA4, Gl2BuA6, and Gl1KeP3. The biocontrol agents were applied as single agents and combination two of them. This study demonstrated that the application of combination biocontrol organisms Pseudomonas fluorescens and AM Fungi provided were more effective than single application. The combination of Par1-Cv and Gl1BuA4 isolates was the most effective to control Fusarium wilt and followed by the combination of Par1-Cv and Gl2BuA6 and Par2-Jt1 and Gl1P3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pseudomonad%20fluorescens%20%28Pf%29" title="pseudomonad fluorescens (Pf)">pseudomonad fluorescens (Pf)</a>, <a href="https://publications.waset.org/abstracts/search?q=arbuscular%20mychorrhizae%20fungi%20%28AM%20Fungi%29%20indigenous%20isolates" title=" arbuscular mychorrhizae fungi (AM Fungi) indigenous isolates"> arbuscular mychorrhizae fungi (AM Fungi) indigenous isolates</a>, <a href="https://publications.waset.org/abstracts/search?q=fusarium%20oxysporum%20f.%20sp.%20cubense" title=" fusarium oxysporum f. sp. cubense"> fusarium oxysporum f. sp. cubense</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20rhizosphere" title=" soil rhizosphere"> soil rhizosphere</a> </p> <a href="https://publications.waset.org/abstracts/37182/combined-aplication-of-indigenous-pseudomonas-fluorescens-and-the-am-fungi-as-the-potential-biocontrol-agents-of-banana-fusarium-wilt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Trends of Change of Political Participation of Young Voters in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Najmuddin%20Rasul">Najmuddin Rasul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to determine whether media usage and change of citizenship norms influence trends of change of political participation of young voters in Indonesia. The focus of this study is to examine citizenship norms in the context of the development of information and communication technology influence political participation in the context of Indonesia's transition to democracy. The main theoretical framework is media and political participation. For data gathering, 384 young voters between the ages of 17 to 40 years were interviewed in Padang, West Sumatra, Indonesia. The results of this study reveal that gender, age and educational background of respondents did not influence significantly media usage and citizenship norms. The results also show that educational background is not a factor that distinguishes media usage but it becomes differentiating factor in citizenship norms. The results further show that media usage has a significant correlation with citizenship norms and citizenship norms has a significant relationship with political participation. In addition, media usage and citizenship norm significantly influence political participation. The sub-dimensions the citizenship norms (compliance, duty, and engaged citizenship) provides a significant contribution to the sub-dimensions of political participation (traditional political participation, modern political participation, civic political participation). Based on the findings it can be concluded that the political euphoria in the era of transition to democracy has changed pattern of media usage and citizenship norms among the young generation in Indonesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20participation" title="political participation">political
