One of the ways to overcome musculoskeletal complaints is by stretching. This study aimed to examine the prevalence of MSDs and the effect of a 2-week stretching exercise program using the Indonesian Ministry of Health's stretching video on changes in musculoskeletal pain intensity in FA on commercial aircraft in Indonesia. Methods: A pre-post study was conducted using Nordic Musculoskeletal Questionnaire (NMQ) for MSDs’ identification and Visual Analog Scale (VAS) as pain intensity measurement. Data was collected and then analyzed using SPSS with Wilcoxon test. The change in pain intensity was considered significant if the p value was less than 0.05. Results: The results showed that 92% of the FA (n=75) had MSDs in at least 1 area of the body in the last 12 months. Thirty-four respondents participated as subjects. The complaint level score in 28 body areas before intervention was a median of 34 (29-84), with pain intensity of a median of 6 (2-9) became a median of 32 (28-67) and a median of 3 (0-9) after the intervention, respectively, with p-value <0.001. Conclusion: The stretching exercise program showed significant changes in the complaint level scores in 28 body areas (p < 0.001) and pain intensity before and after the stretching exercise intervention (p < 0.001). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flight%20attendant" title="flight attendant">flight attendant</a>, <a href="https://publications.waset.org/abstracts/search?q=MSDs" title=" MSDs"> MSDs</a>, <a href="https://publications.waset.org/abstracts/search?q=Nordic%20Musculoskeletal%20Questionnaire" title=" Nordic Musculoskeletal Questionnaire"> Nordic Musculoskeletal Questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=stretching%20exercise%20program" title=" stretching exercise program"> stretching exercise program</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20analog%20scale" title=" visual analog scale"> visual analog scale</a> </p> <a href="https://publications.waset.org/abstracts/153186/changes-in-pain-intensity-of-musculoskeletal-disorders-in-flight-attendants-after-stretching-exercise-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153186.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">83</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">30</span> Affectness of Emotional Intelligence on Employee Profesionalism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanisa%20Damayanti%20Yuningsih">Vanisa Damayanti Yuningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Employee professionalism is certainly the hope for every company to create a good working environment. Emotional intelligence is one of the factors that determine the success of professionalism, for, in emotional intelligence, an employee can control his ego and can understand and understand his coworkers and thus create a dynamic environment in which to work. Each employee is encouraged to have professionalism in order to optimize his resources. This professionalism is shown by employees being able to do their work and taking responsibility in their profession by involving controlled feelings and emotions. The problem which is drawn from this research is how emotional intelligence can affect the professional attitudes of employees. The purpose of this research is to find out how far emotional intelligence goes in the professional manner of employees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=professionalism" title="professionalism">professionalism</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title=" emotional intelligence"> emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20environment" title=" work environment"> work environment</a>, <a href="https://publications.waset.org/abstracts/search?q=company" title=" company"> company</a> </p> <a href="https://publications.waset.org/abstracts/145394/affectness-of-emotional-intelligence-on-employee-profesionalism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145394.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">163</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">29</span> Pre-Processing of Ultrasonography Image Quality Improvement in Cases of Cervical Cancer Using Image Enhancement </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Supriyanti">Retno Supriyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Teguh%20Budiono"> Teguh Budiono</a>, <a href="https://publications.waset.org/abstracts/search?q=Yogi%20Ramadhani"> Yogi Ramadhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Haris%20B.%20Widodo"> Haris B.

In this diagnosis doctors usually perform several tests to determine the presence of cervical cancer in a patient. However, these checks require support equipment to get the results in more detail. One is by using ultrasonography. However, for the developing countries most of the existing ultrasonography has a low resolution. The goal of this research is to obtain abnormalities on low-resolution ultrasound images especially for cervical cancer case. In this paper, we emphasize our work to use Image Enhancement for pre-processing image quality improvement.

This liquid oil mixture contains various kinds of useful compounds such as aromatic compounds and phenolic compounds. These compounds are widely used as raw material for insecticides, dyes, medicines, perfumes, coloring matters, and many others. This research investigates thermodynamic modelling of liquid-liquid equilibria (LLE) in solvent extraction of o-Cresol from the coal tar. The equilibria are modeled by ternary components of Wohl, Van Laar, and Three-Suffix Margules models. The values of the parameters involved are obtained by curve-fitting to the experimental data. Based on the comparison between calculated and experimental data, it turns out that among the three models studied, the Three-Suffix Margules seems to be the best to predict the LLE of o-Cresol for those system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal%20tar" title="coal tar">coal tar</a>, <a href="https://publications.waset.org/abstracts/search?q=o-Cresol" title=" o-Cresol"> o-Cresol</a>, <a href="https://publications.waset.org/abstracts/search?q=Wohl" title=" Wohl"> Wohl</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Laar" title=" Van Laar"> Van Laar</a>, <a href="https://publications.waset.org/abstracts/search?q=three-suffix%20margules" title=" three-suffix margules"> three-suffix margules</a> </p> <a href="https://publications.waset.org/abstracts/46569/liquid-liquid-equilibrium-study-in-solvent-extraction-of-o-cresol-from-coal-tar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46569.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">277</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> Calculating Ventricle’s Area Based on Clinical Dementia Rating Values on Coronal MRI Image</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Supriyanti">Retno Supriyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ays%20Rahmadian%20Subhi"> Ays Rahmadian Subhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yogi%20Ramadhani"> Yogi Ramadhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Haris%20B.%20Widodo"> Haris B.

The severity of the Alzheimer can be measured using a scale called Clinical Dementia Rating (CDR) based on a doctor's diagnosis of the patient's condition. Currently, diagnosis of Alzheimer often uses MRI machine, to know the condition of part of the brain called Hippocampus and Ventricle. MRI image itself consists of 3 slices, namely Coronal, Sagittal and Axial. In this paper, we discussed the measurement of the area of the ventricle especially in the Coronal slice based on the severity level referring to the CDR value. We use Active Contour method to segment the ventricle’s region, therefore that ventricle’s area can be calculated automatically. The results show that this method can be used for further development in the automatic diagnosis of Alzheimer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer" title="Alzheimer">Alzheimer</a>, <a href="https://publications.waset.org/abstracts/search?q=CDR" title=" CDR"> CDR</a>, <a href="https://publications.waset.org/abstracts/search?q=coronal" title=" coronal"> coronal</a>, <a href="https://publications.waset.org/abstracts/search?q=ventricle" title=" ventricle"> ventricle</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20contour" title=" active contour"> active contour</a> </p> <a href="https://publications.waset.org/abstracts/91350/calculating-ventricles-area-based-on-clinical-dementia-rating-values-on-coronal-mri-image" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91350.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">266</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">26</span> Combined Effect of Heat Stimulation and Delay Addition of Superplasticizer with Slag on Fresh and Hardened Property of Mortar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoni%20Wibowo">Antoni Wibowo</a>, <a href="https://publications.waset.org/abstracts/search?q=Harry%20Pujianto"> Harry Pujianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Retno%20Sari%20Saputro"> Dewi Retno Sari Saputro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stock market can provide huge profits in a relatively short time in financial sector; however, it also has a high risk for investors and traders if they are not careful to look the factors that affect the stock market.

In Indonesia, National Health Insurance was first implemented in 2014 and planned to achieve universal health coverage by 2019. However, the little understanding of this new policy lead to increase of complaint in hospital as a health care provider. This is a observational descriptive study with cross sectional design method. Data was collected through in-depth interview with 96 patient from Jemursari Islamic Hospital of Surabaya (Rumah Sakit Islam Jemursari Surabaya) who participate in National Health Insurance.

In determining pregnancy, ultrasonography has many roles, such as to check the position of the fetus, abnormal pregnancy, fetal age and others. Unfortunately, all these things still need to analyze the role of the obstetrician in the sense of image raised by ultrasonography. One of the most striking is the determination of gestational age. Usually, it is done by measuring the length of the fetus manually by obstetricians. In this study, we developed a computer-aided diagnosis for the determination of gestational age by measuring the length of the fetus automatically using edge detection method and image morphology. Results showed that the system is sufficiently accurate in determining the gestational age based image processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20aided%20diagnosis" title="computer aided diagnosis">computer aided diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=gestational%20age" title=" gestational age"> gestational age</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20diameter%20of%20uterus" title=" and diameter of uterus"> and diameter of uterus</a>, <a href="https://publications.waset.org/abstracts/search?q=length%20of%20fetus" title=" length of fetus"> length of fetus</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20detection%20method" title=" edge detection method"> edge detection method</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology%20image" title=" morphology image"> morphology image</a> </p> <a href="https://publications.waset.org/abstracts/46484/edge-detection-and-morphological-image-for-estimating-gestational-age-based-on-fetus-length-automatically" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46484.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">294</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> Kinetics of Growth Rate of Microalga: The Effect of Carbon Dioxide Concentration </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Ambarwati%20Sigit%20Lestari">Retno Ambarwati Sigit Lestari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microalga is one of the organisms that can be considered ideal and potential for raw material of bioenergy production, because the content of lipids in microalga is relatively high. Microalga is an aquatic organism that produces complex organic compounds from inorganic molecules using carbon dioxide as a carbon source, and sunlight for energy supply. Microalga-CO₂ fixation has potential advantages over other carbon captures and storage approaches, such as wide distribution, high photosynthetic rate, good environmental adaptability, and ease of operation. The rates of growth and CO₂ capture of microalga are influenced by CO₂ concentration and light intensity. This study quantitatively investigates the effects of CO₂ concentration on the rates of growth and CO₂ capture of a type of microalga, cultivated in bioreactors. The works include laboratory experiments as well as mathematical modelling. The mathematical models were solved numerically and the accuracy of the model was tested by the experimental data. It turned out that the mathematical model proposed can well quantitatively describe the growth and CO₂ capture of microalga, in which the effects of CO₂ concentration can be observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Microalga" title="Microalga">Microalga</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20concentration" title=" CO2 concentration"> CO2 concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=photobioreactor" title=" photobioreactor"> photobioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model "> mathematical model </a> </p> <a href="https://publications.waset.org/abstracts/106192/kinetics-of-growth-rate-of-microalga-the-effect-of-carbon-dioxide-concentration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106192.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">21</span> A Simple and Easy-To-Use Tool for Detecting Outer Contour of Leukocytes Based on Image Processing Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Supriyanti">Retno Supriyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Best%20Leader%20Nababan"> Best Leader Nababan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yogi%20Ramadhani"> Yogi Ramadhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyu%20Siswandari"> Wahyu Siswandari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blood cell morphology is an important parameter in a hematology test. Currently, in developing countries, a lot of hematology is done manually, either by physicians or laboratory staff. According to the limitation of the human eye, examination based on manual method will result in a lower precision and accuracy. In addition, the hematology test by manual will further complicate the diagnosis in some areas that do not have competent medical personnel. This research aims to develop a simple tool in the detection of blood cell morphology-based computer. In this paper, we focus on the detection of the outer contour of leukocytes. The results show that the system that we developed is promising for detecting blood cell morphology automatically.

Indonesia is blessed with abundant natural resources and a choices of energy resources to generate electricity among other are coal, gas, biomass, hydro to geothermal, creating a fierce competition in electricity tariffs. While geothermal is inline with energy security principle and green growth initiative, it requires a huge capital funding. Geothermal electricity development consists of phases of project with each having its own financial characteristics. The Indonesian government has set a support in the form of ceiling price of geothermal electricity tariff by 11 U.S cents / kWh. However, the government did not set a levelized cost of geothermal, as an indication of lower limit capacity class, to which support is given. The government should establish a levelized cost of geothermal energy to reflect its financial capability in supporting geothermal development. Aside of that, the government is also need to establish a structured tariff calculation to reflect a fair and transparent business cooperation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=load%20fator" title="load fator">load fator</a>, <a href="https://publications.waset.org/abstracts/search?q=levelized%20cost%20of%20geothermal" title=" levelized cost of geothermal"> levelized cost of geothermal</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal%20power%20plant" title=" geothermal power plant"> geothermal power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20tariff%20calculation" title=" structured tariff calculation"> structured tariff calculation</a> </p> <a href="https://publications.waset.org/abstracts/7923/structured-tariff-calculation-to-promote-geothermal-for-energy-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7923.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">440</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> Analysis of Bio-Oil Produced by Pyrolysis of Coconut Shell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20S.%20Fardhyanti">D.

One of the technologies to convert biomass as an energy source is pyrolysis which is converting biomass into more valuable products, such as bio-oil. Bio-oil is a liquid which is produced by steam condensation process from the pyrolysis of coconut shells. The composition of a coconut shell e.g. hemicellulose, cellulose and lignin will be oxidized to phenolic compounds as the main component of the bio-oil. The phenolic compounds in bio-oil are corrosive; they cause various difficulties in the combustion system because of a high viscosity, low calorific value, corrosiveness, and instability. Phenolic compounds are very valuable components which phenol has used as the main component for the manufacture of antiseptic, disinfectant (known as Lysol) and deodorizer. The experiments typically occurred at the atmospheric pressure in a pyrolysis reactor at temperatures ranging from 300 <sup>o</sup>C to 350 <sup>o</sup>C with a heating rate of 10 <sup>o</sup>C/min and a holding time of 1 hour at the pyrolysis temperature. The Gas Chromatography-Mass Spectroscopy (GC-MS) was used to analyze the bio-oil components. The obtained bio-oil has the viscosity of 1.46 cP, the density of 1.50 g/cm<sup>3</sup>, the calorific value of 16.9 MJ/kg, and the molecular weight of 1996.64. By GC-MS, the analysis of bio-oil showed that it contained phenol (40.01%), ethyl ester (37.60%), 2-methoxy-phenol (7.02%), furfural (5.45%), formic acid (4.02%), 1-hydroxy-2-butanone (3.89%), and 3-methyl-1,2-cyclopentanedione (2.01%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-oil" title="bio-oil">bio-oil</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title=" pyrolysis"> pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut%20shell" title=" coconut shell"> coconut shell</a>, <a href="https://publications.waset.org/abstracts/search?q=phenol" title=" phenol"> phenol</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography-mass%20spectroscopy" title=" gas chromatography-mass spectroscopy"> gas chromatography-mass spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/67250/analysis-of-bio-oil-produced-by-pyrolysis-of-coconut-shell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67250.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">18</span> Auditor with the Javanese Characters: Revealing the Relationship towards Its Client</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krisna%20Damayanti">Krisna Damayanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Negative issue about the relationship between auditors and clients often heard. It arises in view of the rise of a variety of phenomena resulting from the audit practice of greed and do not appreciate the independence of the audit profession and professional code of ethics. It is a logical consequence of the practice of capitalism in accounting. The purpose of this paper would like to uncover the existing auditing practices in Indonesia, especially Java, which is associated with a strong influence of Javanese culture with reluctant/"shy", politely, "legowo", "ngemong" friendly, "not mentholo", "tepo seliro", "ngajeni", "acquiescent". The method used by interpretive approach that emphasizes the role of language, interpret and understand and see social reality as something other than a label, name or concept. Auditing practices in each country has a culture that will affect the standard set by those regulatory standards although there has been an adaptation of IAS. In Indonesia the majority of parties dominated by Javanesse racial regulators, so Java culture is embedded in every audit practices thus conditions in Java requires auditors to behave like that, sometimes interfere with standard Java code of conduct that must be executed by an auditor. Auditors who live in Java have the characters of Javanese culture that is hard to avoid in the audit practice. However, in practice, the auditor still are relevant in their profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auditors" title="auditors">auditors</a>, <a href="https://publications.waset.org/abstracts/search?q=java" title=" java"> java</a>, <a href="https://publications.waset.org/abstracts/search?q=character" title=" character"> character</a>, <a href="https://publications.waset.org/abstracts/search?q=profession" title=" profession"> profession</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20of%20ethics" title=" code of ethics"> code of ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=client" title=" client"> client</a> </p> <a href="https://publications.waset.org/abstracts/20814/auditor-with-the-javanese-characters-revealing-the-relationship-towards-its-client" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20814.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">441</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">17</span> Sulfide Removal from Liquid Using Biofilm on Packed Bed of Salak Fruit Seeds </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Ambarwati%20Sigit%20Lestari">Retno Ambarwati Sigit Lestari</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyudi%20Budi%20Sediawan"> Wahyudi Budi Sediawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarto%20Sarto"> Sarto Sarto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on the removal of sulfide from liquid solution using biofilm on packed bed of salak fruit seeds.

This liquid oil mixture contains various kind of useful compounds such as benzoic aromatic compounds and phenolic compounds. These compounds are widely used as raw material for insecticides, dyes, medicines, perfumes, coloring matters, and many others. The coal tar was collected by pyrolysis process of coal obtained from PT Kaltim Prima Coal and Arutmin-Kalimantan. The experiments typically occurred at the atmospheric pressure in a laboratory furnace at temperatures ranging from 300 to 550oC with a heating rate of 10oC/min and a holding time of 1 hour at the pyrolysis temperature. Nitrogen gas has been used to obtain the inert condition and to carry the gaseous pyrolysis products. The pyrolysis transformed organic materials into gaseous components, small quantities of liquid, and a solid residue (coke) containing fixed amount of carbon and ash. The composition of gas which is produced from the pyrolysis is carbon monoxide, hydrogen, methane, and other hydrocarbon compounds. The gas was condensed and the liquid containing oil/tar and water was obtained. The Gas Chromatography-Mass Spectroscopy (GC-MS) was used to analyze the coal tar components. The obtained coal tar has the viscosity of 3.12 cp, the density of 2.78 g/cm3, the calorific value of 11,048.44 cal/g, and the molecular weight of 222.67.

Their performances in sulfide removal were experimentally observed. In doing so, the salak fruit seeds containing biofilm were then used as packing material in a cylinder. Biogas obtained from biological treatment, which contains 27.95 ppm of hydrogen sulfide was flown through the packed bed. The hydrogen sulfide from the biogas was absorbed in the biofilm and then degraded by the microbes in the biofilm. The hydrogen sulfide concentrations at a various axial position and various times were analyzed. A set of simple kinetics model for the rate of the sulfide removal and the bacterial growth was proposed. Since the biofilm is very thin, the sulfide concentration in the Biofilm at a certain axial position is assumed to be uniform. The simultaneous ordinary differential equations obtained were then solved numerically using Runge-Kutta method. The values of the parameters were also obtained by curve-fitting. The accuracy of the model proposed was tested by comparing the calculation results using the model with the experimental data obtained. It turned out that the model proposed can describe the removal of sulfide liquid using bio-filter in the packed bed. The biofilter could remove 89,83 % of the hydrogen sulfide in the feed at 2.5 hr of operation and biogas flow rate of 30 L/hr. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sulfur-oxidizing%20bacteria" title="sulfur-oxidizing bacteria">sulfur-oxidizing bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=salak%20fruit%20seeds" title=" salak fruit seeds"> salak fruit seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=packing%20material" title=" packing material"> packing material</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a> </p> <a href="https://publications.waset.org/abstracts/41726/kinetics-of-hydrogen-sulfide-removal-from-biogas-using-biofilm-on-packed-bed-of-salak-fruit-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41726.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">222</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> Agricultural Education by Media in Yogyakarta, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Dwi%20Wahyuningrum">Retno Dwi Wahyuningrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunarru%20Samsi%20Hariadi"> Sunarru Samsi Hariadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Education in agriculture is very significant; in a way that it can support farmers to improve their business.

The study started from October 2014 to November 2015 by interviewing the respondents using a questionnaire which included 20 questions on knowledge, 20 questions on attitude, and 20 questions on adopting motivation. The data for the attitude and the adopting motivation were processed into Likert scale, then it was tested for validity and reliability. Differences in the levels of knowledge, attitude, and motivation were tested based on percentage of average score intervals of them and categorized into five interpretation levels. The results show that printed, audio, and audio-visual media give different impacts to the farmers. First, all media make farmers very aware to agricultural innovation, but the highest percentage is on theatrical play. Second, the most effective media to raise the attitude is interactive dialogue on Radio. Finally, printed media, especially comic, is the most effective way to improve the adopting motivation of farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20education" title="agricultural education">agricultural education</a>, <a href="https://publications.waset.org/abstracts/search?q=printed%20media" title=" printed media"> printed media</a>, <a href="https://publications.waset.org/abstracts/search?q=audio%20media" title=" audio media"> audio media</a>, <a href="https://publications.waset.org/abstracts/search?q=audio-visual%20media" title=" audio-visual media"> audio-visual media</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer%20knowledge" title=" farmer knowledge"> farmer knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer%20attitude" title=" farmer attitude"> farmer attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer%20adopting%20motivation" title=" farmer adopting motivation"> farmer adopting motivation</a> </p> <a href="https://publications.waset.org/abstracts/77915/agricultural-education-by-media-in-yogyakarta-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77915.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">211</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> Well Water Pollution Caused by Central Batik Industry in Kliwonan, Sragen, Central Java, Indonesia in Ecofeminism Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Intan%20Purnama%20Sari">Intan Purnama Sari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fitri%20Damayanti"> Fitri Damayanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabiila%20Yumna%20Ghina"> Nabiila Yumna Ghina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kliwonan, Sragen is a famous central batik industry village. In the process of the industry, women are placed into the central role but marginalized in economic mode. Women have the double burden on domestic sector and public sector (work as craftsmen batik). The existence of the batik industry bring on issues related to the pollution of water resources as a result of waste water with the marginalized of women. This research aims to examine the relevance of the pollution of the water from the well in Kliwonan with women as the biggest role holders through ecofeminism perspective. To examine these aspects then made observations, documentation, and interview against women batik craftsmen. The results of the study showed that the wells as sources of water to the inhabitants of contaminated because the liquid waste water batik industry. The impact of women must buy clean water each month to meet the needs of the household water with the reward that is obtained from the result of labor as much as Rp 12,000 per day. It proves the marginalized women on economic mode. Based on the results of research done, it can be concluded that the required environmental planning to promote how women do the rescue environment.

Most of the old quarter city of Surabaya is an ancient Kampong. Ketandan is one ancient Kampong in the center of Surabaya, surrounded by a thriving trade area. These conditions make Kampong vulnerably degraded of environmental quality and tended to lose their cultural identity. Norms and values eroded by the rapid development of its local surroundings. Through Kampong conservation programs, Surabaya city government established Ketandan as one of the urban heritage. To achieve the ideal condition of urban heritage, public participation is required. One thing that can generate a motivation for Kampong Ketandan community participation is to rediscover the identity of Kampong Ketandan. This research aims to explore the appropriate method to rediscover the identity of Kampong Ketandan. Through qualitative research methods, based on observations and focus group discussions, it was concluded that mural mentoring program was the best method that can be accepted by the Kampong community to rediscover their identity. Mural as one of the urban art form, able to motivate Kampong community to express their self and bring an icon to their Kampong. The benefits of this research are to provide input to the city government and the private sector to preserve urban heritage, moreover, to transform an urban heritage into a productive space in urban areas in order to enhance city revenues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kampong" title="Kampong">Kampong</a>, <a href="https://publications.waset.org/abstracts/search?q=Kampong%20Ketandan" title=" Kampong Ketandan"> Kampong Ketandan</a>, <a href="https://publications.waset.org/abstracts/search?q=mural" title=" mural"> mural</a>, <a href="https://publications.waset.org/abstracts/search?q=Surabaya" title=" Surabaya"> Surabaya</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20heritage" title=" urban heritage"> urban heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20art" title=" urban art"> urban art</a> </p> <a href="https://publications.waset.org/abstracts/65678/urban-art-as-an-identity-branding-of-kampong-ketandan-surabaya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65678.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">332</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> Partnership in Eradicating Corruption: Case Study of Indonesia’s Corruption Eradication Commission Partnership with Dompet Dhuafa in Preventing Corruption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asriana%20Issa%20Sofia">Asriana Issa Sofia</a>, <a href="https://publications.waset.org/abstracts/search?q=Retno%20Hendrowati"> Retno Hendrowati</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Kurniaty"> Dewi Kurniaty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims at analyzing the role of Corruption Eradication Commission in combating corruption cases including punishing high-profile corruptors and changing the culture of corruption in Indonesia by strengthening the relations with other agencies. Corruption Eradicating Commission was created in 2002 as Indonesia’s most trusted government institution as the anti-corruption agency that will exercise investigatory and prosecutorial power independently from the executive, legislature, and judiciary. The analysis of partnership addressed the role of collaboration with other institutions including Non-Government Organization, Youth Organization, Governmental Institution and Society. The collaboration is needed due to the limitations of Corruption Eradication Commission in preventing corruption. The collaboration focuses on the intensive communication, strengthening leadership, commitment, and creating trust. The research method used the qualitative study by employing the literature study and having a semi-structured interview with the key informant in Corruption Eradication Commission and its partners. The analysis found that intensive communication, leadership, communication, and creating trust were the important pillars in assisting Corruption Eradication Commission to prevent the incoming seed of corruption.

Their performance in sulfide removal were experimentally observed. Snakefruit seeds were then used as packing material in a cylindrical tube. Biological treatment of hydrogen sulfide from biogas was investigated using biofilm on packed bed of snakefruits seeds. Biogas containing 27,9512 ppm of hydrogen sulfide was flown through the bed. Then the hydrogen sulfide concentrations in the outlet at various times were analyzed. A set of simple kinetics model for the rate of the sulfide removal and the bacterial growth was proposed. The axial sulfide concentration gradient in the flowing liquid are assumed to be steady-state. Mean while the biofilm grows on the surface of the seeds and the oxidation takes place in the biofilm. Since the biofilm is very thin, the sulfide concentration in the biofilm is assumed to be uniform. The simultaneous ordinary differential equations obtained were then solved numerically using Runge-Kutta method. The acuracy of the model proposed was tested by comparing the calcultion results using the model with the experimental data obtained. It turned out that the model proposed can be applied to describe the removal of sulfide liquid using bio-filter in packed bed. The values of the parameters were also obtained by curve-fitting. The biofilter could remove 89,83 % of the inlet of hydrogen sulfide from biogas for 2.5 h, and optimum loading of 8.33 ml/h. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulfur-oxidizing%20bacteria" title="Sulfur-oxidizing bacteria">Sulfur-oxidizing bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=snakefruits%20seeds" title=" snakefruits seeds"> snakefruits seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=packing%20material" title=" packing material"> packing material</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a> </p> <a href="https://publications.waset.org/abstracts/27439/hydrogen-sulfide-removal-from-biogas-using-biofilm-on-packed-bed-of-salak-fruit-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27439.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">408</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> Analysis of Ionosphere Anomaly Before Great Earthquake in Java on 2009 Using GPS Tec Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aldilla%20Damayanti%20Purnama%20Ratri">Aldilla Damayanti Purnama Ratri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hendri%20Subakti"> Hendri Subakti</a>, <a href="https://publications.waset.org/abstracts/search?q=Buldan%20Muslim"> Buldan Muslim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ionosphere’s anomalies as an effect of earthquake activity is a phenomenon that is now being studied in seismo-ionospheric coupling. Generally, variation in the ionosphere caused by earthquake activity is weaker than the interference generated by different source, such as geomagnetic storms. However, disturbances of geomagnetic storms show a more global behavior, while the seismo-ionospheric anomalies occur only locally in the area which is largely determined by magnitude of the earthquake. It show that the earthquake activity is unique and because of its uniqueness it has been much research done thus expected to give clues as early warning before earthquake. One of the research that has been developed at this time is the approach of seismo-ionospheric-coupling. This study related the state in the lithosphere-atmosphere and ionosphere before and when earthquake occur. This paper choose the total electron content in a vertical (VTEC) in the ionosphere as a parameter. Total Electron Content (TEC) is defined as the amount of electron in vertical column (cylinder) with cross-section of 1m2 along GPS signal trajectory in ionosphere at around 350 km of height. Based on the analysis of data obtained from the LAPAN agency to identify abnormal signals by statistical methods, obtained that there are an anomaly in the ionosphere is characterized by decreasing of electron content of the ionosphere at 1 TECU before the earthquake occurred. Decreasing of VTEC is not associated with magnetic storm that is indicated as an earthquake precursor. This is supported by the Dst index showed no magnetic interference. <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=DST%20Index" title=" DST Index"> DST Index</a>, <a href="https://publications.waset.org/abstracts/search?q=ionosphere" title=" ionosphere"> ionosphere</a>, <a href="https://publications.waset.org/abstracts/search?q=seismoionospheric%20coupling" title=" seismoionospheric coupling"> seismoionospheric coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=VTEC" title=" VTEC"> VTEC</a> </p> <a href="https://publications.waset.org/abstracts/20603/analysis-of-ionosphere-anomaly-before-great-earthquake-in-java-on-2009-using-gps-tec-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20603.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">586</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> Designing Electronic Kanban in Assembly Line Tailboom at XYZ Corp to Reducing Lead Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadhifah%20A.%20Nugraha">Nadhifah A.

The helicopter's tail called Tailboom is a product of the helicopter division at XYZ Corp, where the Tailboom assembly line is a pull system. Based on observations of existing conditions that occur at XYZ Corp, production is still unable to meet the demands of consumers; lead time occurs greater than the plan agreed upon by the consumers. In the assembly process, each work station experiences a lack of parts and components needed to assemble components. This happens because of the delay in getting the required part information, and there is no warning about the availability of parts needed, it makes some parts unavailable in assembly warehouse. The lack of parts and components from the previous work station causes the assembly process to stop, and the assembly line also stops at the next station. In its completion, the production time was late and not on the schedule. In resolving these problems, the controlling process is needed, which is controlling the assembly line to get all components and subassembly in the right amount and at the right time. This study applies one of Just In Time tools, namely Kanban and automation, should be added as efficiently and effectively communication line becomes electronic Kanban. The problem can be solved by reducing non-value added time, such as waiting time and idle time. The proposed results of controlling the assembly line of Tailboom result in a smooth assembly line without waiting, reduced lead time, and achieving production time according to the schedule agreed with the consumers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kanban" title="kanban">kanban</a>, <a href="https://publications.waset.org/abstracts/search?q=e-Kanban" title=" e-Kanban"> e-Kanban</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20time" title=" lead time"> lead time</a>, <a href="https://publications.waset.org/abstracts/search?q=pull%20system" title=" pull system"> pull system</a> </p> <a href="https://publications.waset.org/abstracts/114704/designing-electronic-kanban-in-assembly-line-tailboom-at-xyz-corp-to-reducing-lead-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114704.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">114</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> Combining the Noble Values of Traditional Architecture on Modern Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dwi%20Retno%20Sri%20Ambarwati">Dwi Retno Sri Ambarwati </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the traditional architecture were getting lost, replaced by modern architecture. The existence of many traditional houses often changing the function and change the values in an effort to adjust to the modern lifestyle, whereas the spiritual background of traditional architectural design is very specific and be the basis for consideration in the construction of the building, both in terms of determining the location of the building, the direction toward building, the spatial pattern and organization of space, zoning, hierarchical space, building form, ornamentation, the selection of building materials, and so on. The changes in function and form will transformed the spiritual values contained in it, because the architecture affects human behavior and reflects the culture. The traditional architecture views the architecture as a concept that has different tendencies in terms of orientation, shape, and attitude toward nature that tends to harmony with the social environment and local culture. The concept of the spirit of place made the architecture looks familiar, not arrogant and give a positive value to the surrounding environment. Every culture has a traditional architecture that full of spiritual values, although in the simplest form. Humans can learn about human values and local wisdom through the positive values that contained in traditional architecture, the desire to balance themselves with nature and the environment, not overbearing, strict adherence to the prevailing norms, openness in public life and intimacy family life that form a harmonious in life. The great and the wise value of traditional architecture should be revived in modern architecture that tends to ignore the spiritual values and more concerned with the functional and aesthetic pleasure, by combining the noble values of traditional architecture into modern architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=combining%20noble%20values" title=" combining noble values"> combining noble values</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=traditional%20architecture" title=" traditional architecture"> traditional architecture</a> </p> <a href="https://publications.waset.org/abstracts/15167/combining-the-noble-values-of-traditional-architecture-on-modern-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15167.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">459</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> Nonparametric Truncated Spline Regression Model on the Data of Human Development Index in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kornelius%20Ronald%20Demu">Kornelius Ronald Demu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Retno%20Sari%20Saputro"> Dewi Retno Sari Saputro</a>, <a href="https://publications.waset.org/abstracts/search?q=Purnami%20Widyaningsih"> Purnami Widyaningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human Development Index (HDI) is a standard measurement for a country's human development. Several factors may have influenced it, such as life expectancy, gross domestic product (GDP) based on the province's annual expenditure, the number of poor people, and the percentage of an illiterate people. The scatter plot between HDI and the influenced factors show that the plot does not follow a specific pattern or form. Therefore, the HDI's data in Indonesia can be applied with a nonparametric regression model. The estimation of the regression curve in the nonparametric regression model is flexible because it follows the shape of the data pattern. One of the nonparametric regression's method is a truncated spline. Truncated spline regression is one of the nonparametric approach, which is a modification of the segmented polynomial functions. The estimator of a truncated spline regression model was affected by the selection of the optimal knots point. Knot points is a focus point of spline truncated functions. The optimal knots point was determined by the minimum value of generalized cross validation (GCV). In this article were applied the data of Human Development Index with a truncated spline nonparametric regression model. The results of this research were obtained the best-truncated spline regression model to the HDI's data in Indonesia with the combination of optimal knots point 5-5-5-4. Life expectancy and the percentage of an illiterate people were the significant factors depend to the HDI in Indonesia. The coefficient of determination is 94.54%. This means the regression model is good enough to applied on the data of HDI in Indonesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20cross%20validation%20%28GCV%29" title="generalized cross validation (GCV)">generalized cross validation (GCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=Human%20Development%20Index%20%28HDI%29" title=" Human Development Index (HDI)"> Human Development Index (HDI)</a>, <a href="https://publications.waset.org/abstracts/search?q=knots%20point" title=" knots point"> knots point</a>, <a href="https://publications.waset.org/abstracts/search?q=nonparametric%20regression" title=" nonparametric regression"> nonparametric regression</a>, <a href="https://publications.waset.org/abstracts/search?q=truncated%20spline" title=" truncated spline"> truncated spline</a> </p> <a href="https://publications.waset.org/abstracts/73701/nonparametric-truncated-spline-regression-model-on-the-data-of-human-development-index-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73701.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">339</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> Investor Beware - Significance of Investor Conduct under the Fair and Equitable Treatment Standard</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damayanti%20Sen">Damayanti Sen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Fair and Equitable Treatment standard has emerged as a core tenet of a formulated legal structure aimed at encouraging investment through the granting of a secure and stable environment for the investor in the Host State. As an absolute, non-contingent standard, it constitutes an independent and reliable system for the protection of the investor and is frequently invoked and applied in investor-state dispute settlement under bilateral and multilateral investment treaties. Thus far, the standard has been examined principally as a measure for determining the responsibility of host countries towards investors and investments. The conduct of investor in applying the Fair and Equitable Treatment Standard is relatively unexplored. Such an assessment may be necessary in light of the development of new defenses to demands of host governments to confine the application of the standard in order to ensure a proper balance between the protection of investors and the inherent right of a State to regulate economic conduct within its borders. This paper explores the implications of including considerations of investor conduct in the determination of whether an act of the host country’s administrative and/or judicial authorities has breached the fair and equitable treatment principle. The need for such defenses are of special concern for governments of developing countries, whose limited resources can affect their ability to provide an effective evaluation of the nature of the proposed investment, and, subsequently, to ensure that the expected benefits are realized. On the basis of conceptual analysis, and emerging international judicial and arbitral case law, this paper suggests that investor duties such as, the avoidance of unconscionable conduct, the reasonable assessment of investment risk in the host country, and a duty to operate an investment reasonably are leading to a new limit upon the fair and equitable treatment standard- one that can be succinctly captured in the phrase “Caveat Investor”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BITs" title="BITs">BITs</a>, <a href="https://publications.waset.org/abstracts/search?q=FET%20Standard" title=" FET Standard"> FET Standard</a>, <a href="https://publications.waset.org/abstracts/search?q=investor%20behavior" title=" investor behavior"> investor behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=arbitral%20case%20law" title=" arbitral case law"> arbitral case law</a> </p> <a href="https://publications.waset.org/abstracts/25203/investor-beware-significance-of-investor-conduct-under-the-fair-and-equitable-treatment-standard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25203.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">313</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> Parameter Estimation of Additive Genetic and Unique Environment (AE) Model on Diabetes Mellitus Type 2 Using Bayesian Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Darmawan">Andi Darmawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Retno%20Sari%20Saputro"> Dewi Retno Sari Saputro</a>, <a href="https://publications.waset.org/abstracts/search?q=Purnami%20Widyaningsih"> Purnami Widyaningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diabetes mellitus (DM) is a chronic disease in human that occurred if pancreas cannot produce enough of insulin hormone or the body uses ineffectively insulin hormone which causes increasing level of glucose in the blood, or it was called hyperglycemia. In Indonesia, DM is a serious disease on health because it can cause blindness, kidney disease, diabetic feet (gangrene), and stroke. The type of DM criteria can also be divided based on the main causes; they are DM type 1, type 2, and gestational. Diabetes type 1 or previously known as insulin-independent diabetes is due to a lack of production of insulin hormone. Diabetes type 2 or previously known as non-insulin dependent diabetes is due to ineffective use of insulin while gestational diabetes is a hyperglycemia that found during pregnancy. The most one type commonly found in patient is DM type 2. The main factors of this disease are genetic (A) and life style (E). Those disease with 2 factors can be constructed with additive genetic and unique environment (AE) model. In this article was discussed parameter estimation of AE model using Bayesian method and the inheritance character simulation on parent-offspring. On the AE model, there are response variable, predictor variables, and parameters were capable of representing the number of population on research. The population can be measured through a taken random sample. The response and predictor variables can be determined by sample while the parameters are unknown, so it was required to estimate the parameters based on the sample. Estimation of AE model parameters was obtained based on a joint posterior distribution. The simulation was conducted to get the value of genetic variance and life style variance. The results of simulation are 0.3600 for genetic variance and 0.0899 for life style variance. Therefore, the variance of genetic factor in DM type 2 is greater than life style. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AE%20model" title="AE model">AE model</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20method" title=" Bayesian method"> Bayesian method</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus%20type%202" title=" diabetes mellitus type 2"> diabetes mellitus type 2</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20style" title=" life style"> life style</a> </p> <a href="https://publications.waset.org/abstracts/73672/parameter-estimation-of-additive-genetic-and-unique-environment-ae-model-on-diabetes-mellitus-type-2-using-bayesian-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73672.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">284</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> Parameter Estimation of Gumbel Distribution with Maximum-Likelihood Based on Broyden Fletcher Goldfarb Shanno Quasi-Newton</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Retno%20Sari%20Saputro">Dewi Retno Sari Saputro</a>, <a href="https://publications.waset.org/abstracts/search?q=Purnami%20Widyaningsih"> Purnami Widyaningsih</a>, <a href="https://publications.waset.org/abstracts/search?q=Hendrika%20Handayani"> Hendrika Handayani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extreme data on an observation can occur due to unusual circumstances in the observation. The data can provide important information that can’t be provided by other data so that its existence needs to be further investigated. The method for obtaining extreme data is one of them using maxima block method. The distribution of extreme data sets taken with the maxima block method is called the distribution of extreme values. Distribution of extreme values is Gumbel distribution with two parameters. The parameter estimation of Gumbel distribution with maximum likelihood method (ML) is difficult to determine its exact value so that it is necessary to solve the approach. The purpose of this study was to determine the parameter estimation of Gumbel distribution with quasi-Newton BFGS method. The quasi-Newton BFGS method is a numerical method used for nonlinear function optimization without constraint so that the method can be used for parameter estimation from Gumbel distribution whose distribution function is in the form of exponential doubel function. The quasi-New BFGS method is a development of the Newton method. The Newton method uses the second derivative to calculate the parameter value changes on each iteration. Newton's method is then modified with the addition of a step length to provide a guarantee of convergence when the second derivative requires complex calculations. In the quasi-Newton BFGS method, Newton's method is modified by updating both derivatives on each iteration. The parameter estimation of the Gumbel distribution by a numerical approach using the quasi-Newton BFGS method is done by calculating the parameter values that make the distribution function maximum. In this method, we need gradient vector and hessian matrix. This research is a theory research and application by studying several journals and textbooks. The results of this study obtained the quasi-Newton BFGS algorithm and estimation of Gumbel distribution parameters. The estimation method is then applied to daily rainfall data in Purworejo District to estimate the distribution parameters. This indicates that the high rainfall that occurred in Purworejo District decreased its intensity and the range of rainfall that occurred decreased. <p class="card-text"><strong>Keywords:</strong> <a
