Concerning central lesions, the sensitivity of endobronchial forceps biopsy of a visible endobronchial lesion is 74%. The aim is to determine the distribution of lung cancer types of patients diagnosed with and who underwent bronchoscopy at General Ahmad Yani Metro Hospital. Methods: This study is a cross-sectional descriptive study. Data are obtained from histopathological results of lung malignancy through bronchoscopy either from forceps biopsy, washing and brushing. Results: Lung cancer is more found in men (72.2%) than women (27.8%). The average age for men ranges 57 years old for Non-Small Cell and 56 years old for Small Cell case. Most histopathology found in non-small cell lung cancer (87.7%), with adenocarcinoma as the most common type (68.4%), followed by squamous cell carcinoma (29.1%). Findings for adenocarcinoma showed that men had an incidence of 64.8% and women had an incidence of 35.2%. Like NSCLC, men can have up to 90% of cases of SCLC compared to 10% in women. In addition to non-small cell and small cell types, other types, such as large cells and renal carcinoma metastases, were obtained. Conclusions: Adenocarcinoma lung cancer is the most widely obtained type with predominantly male patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bronchoscopy" title="bronchoscopy">bronchoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=forceps%20biopsy" title=" forceps biopsy"> forceps biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=washing" title=" washing"> washing</a>, <a href="https://publications.waset.org/abstracts/search?q=brushing" title=" brushing"> brushing</a> </p> <a href="https://publications.waset.org/abstracts/195109/patients-undergoing-diagnostic-bronchoscopy-at-general-ahmad-yani-hospital-in-2023-a-profile-of-lung-cancer-types" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195109.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">2</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">11</span> Money Laundering and Governance in Cryptocurrencies: The Double-Edged Sword of Blockchain Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiaqi%20Yan">Jiaqi Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yani%20Shi"> Yani Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the growing popularity of bitcoin transactions, criminals have exploited the bitcoin like cryptocurrencies, and cybercriminals such as money laundering have thrived.

This study aimed to examine the effect of a family-based DOTS support program on adherence to health behaviors in patients with pulmonary TB. Sixty TB patients and their families were selected using cluster randomization of community health centers. The subjects were assigned into a control group, who received the routine care, and an experimental group, who received both routine care and care from the family-based DOTS support program. Paired t-test and the independent t-test were applied. The total score of adherence to health behaviors in the experimental group was significantly higher after receiving care from the family-based DOTS support program than the pretest score (t = -10.34, p < .001). Suggestions were made to expand the application of this program in various contexts and to extend knowledge for nursing practices and research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-care%20deficit%20nursing%20theory" title="self-care deficit nursing theory">self-care deficit nursing theory</a>, <a href="https://publications.waset.org/abstracts/search?q=family-based%20DOTS%20program" title=" family-based DOTS program"> family-based DOTS program</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20tuberculosis" title=" pulmonary tuberculosis"> pulmonary tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=adherence" title=" adherence"> adherence</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20behaviors" title=" health behaviors"> health behaviors</a> </p> <a href="https://publications.waset.org/abstracts/9890/effect-of-family-based-dots-support-program-on-adherence-to-health-behaviors-among-patients-with-pulmonary-tuberculosis-in-bandung-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9890.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">464</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">9</span> Melodic and Temporal Structure of Indonesian Sentences of Sitcom "International Class" Actors: Prosodic Study with Experimental Phonetics Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tri%20Sulistyaningtyas">Tri Sulistyaningtyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Yani%20Suryani"> Yani Suryani</a>, <a href="https://publications.waset.org/abstracts/search?q=Dana%20Waskita"> Dana Waskita</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Handayani%20Sukaemi"> Linda Handayani Sukaemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferry%20Fauzi%20Hermawan"> Ferry Fauzi Hermawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The enthusiasm of foreigners studying the Indonesian language by Foreign Speakers (BIPA) was documented in a sitcom "International Class". Tone and stress when they speak the Indonesian language is unique and different from Indonesian pronunciation. By using the Praat program, this research aims to describe prosodic Indonesian language which is spoken by ‘International Class” actors consisting of Abbas from Nigeria, Lee from Korea, and Kotaro from Japan. Data for the research are taken from the video sitcom "International Class" that aired on Indonesian television. The results of this study revealed that pitch movement that arises when pronouncing Indonesian sentences was up and down gradually, there is also a rise and fall sharply. In terms of stress, respondents tend to contain a lot of stress when pronouncing Indonesian sentences. Meanwhile, in terms of temporal structure, the duration pronouncing Indonesian sentences tends to be longer than that of Indonesian speakers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melodic%20structure" title="melodic structure">melodic structure</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20structure" title=" temporal structure"> temporal structure</a>, <a href="https://publications.waset.org/abstracts/search?q=prosody" title=" prosody"> prosody</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20phonetics" title=" experimental phonetics"> experimental phonetics</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20class" title=" international class"> international class</a> </p> <a href="https://publications.waset.org/abstracts/63808/melodic-and-temporal-structure-of-indonesian-sentences-of-sitcom-international-class-actors-prosodic-study-with-experimental-phonetics-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63808.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">8</span> The Effects of Source and Timing on the Acceptance of New Product Recommendation: A Lab Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yani%20Shi">Yani Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaqi%20Yan"> Jiaqi Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new product is important for companies to extend consumers and manifest competitiveness. New product often involves new features that consumers might not be familiar with while it may also have a competitive advantage to attract consumers compared to established products. However, although most online retailers employ recommendation agents (RA) to influence consumers’ product choice decision, recommended new products are not accepted and chosen as expected. We argue that it might also be caused by providing a new product recommendation in the wrong way at the wrong time. This study seeks to discuss how new product evaluations sourced from third parties could be employed in RAs as evidence of the superiority for the new product and how the new product recommendation could be provided to a consumer at the right time so that it can be accepted and finally chosen during the consumer’s decision-making process. A 2*2 controlled laboratory experiment was conducted to understand the selection of new product recommendation sources and recommendation timing. Human subjects were randomly assigned to one of the four treatments to minimize the effects of individual differences on the results. Participants were told to make purchase choices from our product categories. We find that a new product recommended right after a similar existing product and with the source of the expert review will be more likely to be accepted. Based on this study, both theoretical and practical contributions are provided regarding new product recommendation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20product%20recommendation" title="new product recommendation">new product recommendation</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20timing" title=" recommendation timing"> recommendation timing</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20source" title=" recommendation source"> recommendation source</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20agents" title=" recommendation agents"> recommendation agents</a> </p> <a href="https://publications.waset.org/abstracts/96996/the-effects-of-source-and-timing-on-the-acceptance-of-new-product-recommendation-a-lab-experiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96996.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">154</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">7</span> A Modeling Approach for Blockchain-Oriented Information Systems Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiaqi%20Yan">Jiaqi Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yani%20Shi"> Yani Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The blockchain technology is regarded as the most promising technology that has the potential to trigger a technological revolution. However, besides the bitcoin industry, we have not yet seen a large-scale application of blockchain in those domains that are supposed to be impacted, such as supply chain, financial network, and intelligent manufacturing. The reasons not only lie in the difficulties of blockchain implementation, but are also root in the challenges of blockchain-oriented information systems design. As the blockchain members are self-interest actors that belong to organizations with different existing information systems. As they expect different information inputs and outputs of the blockchain application, a common language protocol is needed to facilitate communications between blockchain members. Second, considering the decentralization of blockchain organization, there is not any central authority to organize and coordinate the business processes. Thus, the information systems built on blockchain should support more adaptive business process. This paper aims to address these difficulties by providing a modeling approach for blockchain-oriented information systems design. We will investigate the information structure of distributed-ledger data with conceptual modeling techniques and ontology theories, and build an effective ontology mapping method for the inter-organization information flow and blockchain information records. Further, we will study the distributed-ledger-ontology based business process modeling to support adaptive enterprise on blockchain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20systems%20modeling" title=" information systems modeling"> information systems modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20process" title=" business process"> business process</a> </p> <a href="https://publications.waset.org/abstracts/69091/a-modeling-approach-for-blockchain-oriented-information-systems-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69091.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">449</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">6</span> Hazard Alert in Malaysia Related to Occupational Safety and Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atikah%20Binti%20Azudin">Atikah Binti Azudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurin%20Nazlah%20Binti%20Muhamad%20Yani"> Nurin Nazlah Binti Muhamad Yani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Alya%20Nadhirah%20Binti%20Naaidith"> Nur Alya Nadhirah Binti Naaidith</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Amylia%20Wahida%20Binti%20Mat%20Ayob"> Nur Amylia Wahida Binti Mat Ayob</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurshamimi%20Shakirah%20Binti%20Suboh"> Nurshamimi Shakirah Binti Suboh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Auni%20Batrisyia%20Binti%20Md.%20Zaini"> Nur Auni Batrisyia Binti Md.

The alert gives guidelines for proper processes, practices, and controls to be applied. When operated in accordance with the manufacturer's instructions, any machine or tool utilized at work provides a safe and dependable platform for workers to accomplish job duties. However, when not utilized appropriately, the machine might pose a major hazard to employees. Employers have a duty to keep employees safe in this scenario. This Hazard Alert outlines specific occupational dangers and the controls that employers must apply to prevent injury or fatal accidents. There have been several cases of hazard alerts in Malaysia, which have had a negative impact on a few workers. Looking on the bright side, we can overcome every incident in a variety of ways. One of these is that only qualified individuals operate mobile machinery and equipment. In addition, employees may also perform frequent pre-use inspections of machinery to discover and fix flaws. Hazard alert is very important, and this study would cover a variety of subjects, including the methods employed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safe" title="safe">safe</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=impacts" title=" impacts"> impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=duties." title=" duties."> duties.</a> </p> <a href="https://publications.waset.org/abstracts/166695/hazard-alert-in-malaysia-related-to-occupational-safety-and-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166695.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">92</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">5</span> Prospects in Teaching Arabic Grammatical Structures to Non-Arab Learners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Toyin%20Muritala">Yahya Toyin Muritala</a>, <a href="https://publications.waset.org/abstracts/search?q=Nonglaksana%20Kama"> Nonglaksana Kama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Yani"> Ahmad Yani </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the paper is to investigate various linguistic techniques in enhancing and facilitating the acquisition of the practical knowledge of Arabic grammatical structuring among non-Arab learners of the standard classical Arabic language in non-Arabic speaking academic settings in the course of the current growth of the internationalism and cultural integration in some higher institutions. As the nature of the project requires standard investigations into the unique principal features of Arabic structurings and implications, the findings of the research work suggest some principles to follow in solving the problems faced by learners while acquiring grammatical aspects of Arabic language. The work also concentrates on the the structural features of the language in terms of inflection/parsing, structural arrangement order, functional particles, morphological formation and conformity etc. Therefore, grammatical aspect of Arabic which has gone through major stages in its early evolution of the classical stages up to the era of stagnation, development and modern stage of revitalization is a main subject matter of the paper as it is globally connected with communication and religion of Islam practiced by millions of Arabs and non-Arabs nowadays. The conclusion of the work shows new findings, through the descriptive and analytical methods, in terms of teaching language for the purpose of effective global communication with focus on methods of second language acquisitions by application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language%20structure" title="language structure">language structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20grammar" title=" Arabic grammar"> Arabic grammar</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20Arabic" title=" classical Arabic"> classical Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=intercultural%20communication" title=" intercultural communication"> intercultural communication</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Arabic%20speaking%20environment%20and%20prospects" title=" non-Arabic speaking environment and prospects"> non-Arabic speaking environment and prospects</a> </p> <a href="https://publications.waset.org/abstracts/15270/prospects-in-teaching-arabic-grammatical-structures-to-non-arab-learners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15270.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">400</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">4</span> Structural and Optical Characterization of Rice-Husk-Derived SiO₂ Crystals-reinforced PVA Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suminar%20Pratapa">Suminar Pratapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Agus%20Riyanto"> Agus Riyanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Silmi%20Machmudah"> Silmi Machmudah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sri%20Yani%20Purwaningsih"> Sri Yani Purwaningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to investigate the optical properties of polyvinyl alcohol (PVA) and its prospective applications by adding crystalline silica which is usually used as a reinforcing agent. To do this, we synthesized and evaluated PVA-based composites reinforced with silica crystals, namely cristobalite, derived from rice husk. The experimental procedure involved the production of SiO2 particles using rice husk precursors, which were subsequently subjected to calcination at a rate of 10 °C/min for a duration of 3 hours. This process primarily resulted in the formation of SiO2 crystals in the cristobalite phase, according to X-ray diffraction (XRD). Following this, the crystals were incorporated into polyvinyl alcohol (PVA) via a casting technique, resulting in the formation of composite sheets. The SiO2 contents in the composites were 0, 2.5, 5.0, and 10.%. XRD and Fourier-transform infrared spectroscopy (FTIR) techniques provided confirmation of the composites' successful synthesis, i.e., it did not yield any indications of chemical bonding between polyvinyl alcohol (PVA) and silicon dioxide (SiO2), indicating that the interaction was limited to interfacial reactions. The incorporation of SiO2 crystals resulted in a notable enhancement in UV-vis light absorption and a decrease in the optical band gap. Addition of 2.5, 5.0, and 10.% SiO2, for example, decreases the direct optical band gap of the composites form 5.37, 5.19, and 5.02 eV respectively, while the indirect band gaps of the samples were 4.44, 4.84, and 4.48 eV, correspondingly. These findings emphasize the efficacy of rice husk-derived SiO2 crystals as both reinforcement agents and modifiers of optical properties in the polymer composites, showcasing their significant potential to modify the composite's structural and optical characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rice%20husk" title="rice husk">rice husk</a>, <a href="https://publications.waset.org/abstracts/search?q=cristaline%20SiO%E2%82%82" title=" cristaline SiO₂"> cristaline SiO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=PVA-based%20composites" title=" PVA-based composites"> PVA-based composites</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20characteristics" title=" structural characteristics"> structural characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties." title=" optical properties."> optical properties.</a> </p> <a href="https://publications.waset.org/abstracts/185287/structural-and-optical-characterization-of-rice-husk-derived-sio2-crystals-reinforced-pva-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185287.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">46</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">3</span> Analyzing the Water Quality of Settling Pond after Revegetation at Ex-Mining Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iis%20Diatin">Iis Diatin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yani%20Hadiroseyani"> Yani Hadiroseyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Mujahid"> Muhammad Mujahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Teduh"> Ahmad Teduh</a>, <a href="https://publications.waset.org/abstracts/search?q=Juang%20R.%20Matangaran"> Juang R.

Since 2013 this company stopped the mining activities. The company tries to restore the ecosystem post-mining with rehabilitation activities such as reclamation and revegetation of their ex-mining area. After three years planting the area the trees grown well. Not only planting some tree species but also some cover crop has covered the soil surface. There are two settling ponds located in the middle of the ex-mining area. Those settling pond were built in order to prevent the effect of acid mine drainage. Acid mine drainage (AMD) or the acidic water is created when sulphide minerals are exposed to air and water and through a natural chemical reaction produce sulphuric acid. AMD is the main pollutant at the open pit mining. The objective of the research was to analyze the effect of revegetation on water quality change at the settling pond. The physical and chemical of water quality parameter were measured and analysed at site and at the laboratory. Physical parameter such as temperature, turbidity and total organic matter were analyse. Also heavy metal and some other chemical parameter such as dissolved oxygen, alkalinity, pH, total ammonia nitrogen, nitrate and nitrite were analysed. The result showed that the acidity of first settling pond was higher than that of the second settling pond. Both settling pond water’s contained heavy metal. The turbidity and total organic matter were the parameter of water quality which become better after revegetation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acid%20mine%20drainage" title="acid mine drainage">acid mine drainage</a>, <a href="https://publications.waset.org/abstracts/search?q=ex-mining%20area" title=" ex-mining area"> ex-mining area</a>, <a href="https://publications.waset.org/abstracts/search?q=revegetation" title=" revegetation"> revegetation</a>, <a href="https://publications.waset.org/abstracts/search?q=settling%20pond" title=" settling pond"> settling pond</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/73643/analyzing-the-water-quality-of-settling-pond-after-revegetation-at-ex-mining-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73643.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">303</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">2</span> Comparative Settlement Analysis on the under of Embankment with Empirical Formulas and Settlement Plate Measurement for Reducing Building Crack around of Embankments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safitri%20Nur%20Wulandari">Safitri Nur Wulandari</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ivan%20Adi%20Perdana"> M.

Most of the land in Indonesia has a soft soil, where soft soil is a type of clay that has the consistency of very soft to medium stiff, undrained shear strength, Cu <0:25 kg/cm2, or the estimated value of NSPT <5 blows/ft. This study focuses on the analysis of the effect on preloading load (embarkment) to the amount of settlement ratio on the under of embarkment that will impact on the building cracks around of embarkment. The method used in this research is a superposition method for embarkment distribution on 27 locations with undisturbed soil samples at some borehole point in Java and Kalimantan, Indonesia. Then correlating the results of settlement plate monitoring on the field with Asaoka method. The results of settlement plate monitoring taken from an embarkment of Ahmad Yani airport in Semarang on 32 points. Where the value of Cc (index compressible) soil data based on some laboratory test results, while the value of Cc is not tested obtained from empirical formula Ardhana and Mochtar, 1999. From this research, the results of the field monitoring showed almost the same results with an empirical formulation with the standard deviation of 4% where the formulation of the empirical results of this analysis obtained by linear formula. Value empirical linear formula is to determine the effect of compression heap area as high as 4,25 m is 3,1209x + y = 0.0026 for the slope of the embankment 1: 8 for the same analysis with an initial height of embankment on the field. Provided that at the edge of the embankment settlement worth is not equal to 0 but at a quarter of embankment has a settlement ratio average 0.951 and at the edge of embankment has a settlement ratio 0,049. The influence areas around of embankment are approximately 1 meter for slope 1:8 and 7 meters for slope 1:2.

The weaverbirds are a large family of birds found mostly in Africa, with a few species found in southern Asia and the West Indian Ocean islands. This study assessed the diversity and abundance of weaver birds and their allies within and around Ngel-Nyaki Forest Reserve in Yelwa, Sardauna Local Government Area of Taraba State, Nigeria. A total of 602 weaver birds and allies’ bird species were recorded using the Point Count Line Transect. The data collected during the research period were analyzed using simple percentages, and diversity was calculated using the Shannon Wiener Diversity Index. The fenced (ungrazed area) was more abundant with 351 individuals while the unfenced (grazed area) was less abundant with 251 individuals recorded. In the fenced (ungrazed area), Yellow Bishop (Euplectes capensis) had the highest abundance of (102; 29.01%), followed by Village Weaver (Ploceus cucullatus) (80; 22.79%), then Vieillot's Black Weaver (Ploceus nigerrimus) (40; 11.42%), Red-collard Widowbird (Ploceus ardens) (6; 1.71%), Dark-backed Weaver (5; 1.42%) and the least was Hartlaub Marsh Widowbird (1; 0.28%) while in the unfenced (grazed area), the Village weaver (Ploceus cucullatus) (85; 33.86%) was the most abundant, followed by Spectacled Weaver (Ploceus ocularis) (36; 14.34%), then Yellow Bishop (Euplectes capensis) (30; 11.95%), Baglefecht Weaver (Ploceus baglafecht) (23; 9.16%), Bannerman’s Weaver (Ploceus bannermani) (17; 6.77%) and the least was Yellow-mantled Widowbird (Euplectes macroura) (5; 1.99%). In terms of diversity, there were more weaver bird species in the fenced area with a Shannon Wiener Diversity Index of (Hˈ 2.03417) than in the unfenced area with a Shannon Wiener Diversity Index of (Hˈ 1.862671). The Shannon Wiener Diversity Index in both fenced and unfenced areas is significant. There was more abundance of bird species in the fenced area than in the unfenced area of the Forest Reserve. Thorough research should be conducted on the abundance and diversity of weavers and their allies because we were only able to access 4 km2 out of 46 km2 of land available, according to the Annual Report of Ngel-Nyaki Forest Reserve of 2020. It shows that there are many species of weaver birds and their allies, such as the Black-billed Weaver (Ploceus melanogaster) and the Red-billed Quelea (Quelea quelea), which are available within the reserve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abundance" title="abundance">abundance</a>, <a
