Abstract

Kabupaten Lumajang merupakan wilayah yang rentan terhadap tsunami karena berbatasan langsung dengan Pantai Selatan yang menjadi pusat gempa bumi serta keadaan pesisir pantai selatan Lumajang yang memiliki tingkat kepadatan penduduk dan pemukiman, aktivitas pemerintahan dan perekonomian yang tinggi. Pemetaan tingkat kerentanan tsunami perlu dilakukan sebagai informasi mitigasi dan rencana tata ruang wilayah. Lokasi penelitian adalah 5 (lima) kecamatan di pesisir Pantai Selatan Lumajang yaitu Yosowilangun, Kunir, Tempeh, Pasirian, dan Tempursari. Tujuan penelitian ini adalah membuat peta kerentanan tsunami Kabupaten Lumajang menggunakan Sistem Informasi Geografis (SIG). Pendekatan variabel kerentanan meliputi elevasi daratan, kemiringan, morfometri pantai, penggunaan lahan, jarak dari pantai dan jarak dari sungai. Metodologi penelitian antara lain pengumpulan data primer dan sekunder, pengolahan data parameter yang mewakili tiap variabel kerentanan serta pemberian bobot dan skor. Hasil kajian ini menghasilkan peta-peta variabel kerentanan wilayah penelitian yang selanjutnya dapat digunakan untuk kebijakan pemerintah daerah dan tindakan mitigasi seperti pemetaan tingkat risiko tsunami.

Abstract

Information system integration is needed to support business processes in order to achieve organizational goals. E-Planning and E-Budgeting are systems that are managed by the Department of Communication and Information Technology in Pasuruan Regency. E-Planning is taking part in planning activities, while E-Budgeting is taking part in assigning activities budget. Both systems are working separately that may cause data to exist only in one of those systems. Lacks of data in another system can lead to activity without fund and vice versa. Of course, this problem can disrupt the annual budget plan of the Department of Communication and Information of Pasuruan Regency. This problem can be solved using Enterprise Application Integration (EAI). EAI allows the exchange of data and business processes from several different applications that are interconnected. EAI have 12-steps program that come from best practices for system integration. Despite requiring full steps, this research will only take the first seven steps and then proceed with making UML diagrams. The result of this research are UML diagrams such as use case diagram, class diagram, sequence diagram, and object-oriented data model. These designs can represent business processes that are needed for integration process between E-Planning and E-Budgeting system. These designs will be validated through user debriefing and user validation. These designs can be used as references to build a system to integrate E-Planning and E-Budgeting systems

Abstract

Bangkalan district has the potential unallocated aggregate to be applicated as a concrete mixture in the form of fine aggregates (sand) and coarse aggregates (gravel). In fact, Bangkalan aggregate implies excellent structure, so this material is rarely used as a mixture of concrete because with its fine structure the quality of the concrete produced will be less good. To maximize the use of aggregates from Bangkalan, a concrete mixture design analysis is conducted. The study is based on a test of the physical properties which are classified into five variations. Variation one implies a combination of 5/10 and 10/20 use of gravel and sand from Bangkalan when modification two only change the subject of Bangkalan sand to Lumajang sand with the same proportion. Variation three is treated a combination two with a given 0.3% of additive type D. The variation is increased to be added more additive in variation four with 0.6 % type F. As a final variation, with the same proportion of Lumajang sand and Bangkalan gravel of 5/10 and 10/20 combined with 0.3% additive type D and 0.6% additive type F. The capacity is compared based on physical properties and compression test. As a result, the best proposed design is variation three with a compression test over standard design with 29.44 MPa.

Abstract

Plants have the faculty of  levy the metals in the soil. The consumption of this plants can represent in some situations a health risk to be assessed. The transfer of contaminants from soil to food crops is a major route connecting the soil contamination to human exposure. The Transfer Factors Soil-Plant (TFsp) (the ratio between the concentration of contaminants in plants and the concentration of contaminants in the soil) is a value commonly used in the assessment of exposure and health risks. This research use the BAPPET database (database contents the informations of elements metal traces plants and vegetables). The goal of this research is for define the variable that influent the variability of TFsp and for characterizing their effects from their posteriors distributions using bayesian methods, Metropolis-Hastings. There are 3 metals (Cd, As and Pb), 4 plant types (leaf, fruit, root and tuber) and 2 analysis (using 4 plant types and 3 plant types, without tuber) with 4 models of analysis of varians (ANOVA, using normal and lognormal distribution for likelihood) that used in this research. The results of analysis for 4 plant types is chosing the model II with lognormal distribution for likelihood (yi ~ LN(µi, σi2)) for the best model and for 3 plant types is chosing the model IV with lognormal distribution for likelihood (yi ~ LN(µi, σ2), µi = µ + αi + Bj + δk, Bj ~ N(0, σB2)) for the best model. The contains of metal Cd, As and Pb in leaf has the highest risk for the health because that has the biggest posterior mean of TFsp.

Abstract

Periodic maintenance of power plants is included in the project. Shorter project duration than scheduled indicates the success of the project. For the electricity industry, operating earlier will increase the availability index, which in turn will increase revenue. The standard maintenance work scope of the power plant owner is presented in a detailed work structure of the project as known as Work Breakdown Structure (WBS). Project scheduling is done using network technique with the Critical Path Method (CPM). All activities that are on the critical path can be done crashing to speed up work in shortening the duration of treatment. Crashing is done by utilizing the cost slope of critical activities. So information can be obtained about the costs of several possible durations. The study of power plant maintenance using a cost slope gets an accelerated duration with the smallest cost, which is 28 days. With a maintenance duration of 28 days the total cost is 3,854,670,611 rupiahs and with an additional income of 429,643,368 rupiah from normal income of 21,404,712,886 rupiahs

Abstract

A series of benzylmercaptans carrying different para-substituents were used to form self-assembled monolayers on gold in order to modulate the work funtion of the metal electrode. Ellipsometry, Reflection Absorption Infrared Spectroscopy (RAIRS), and cyclic voltametry were used to chracterized the structure of the monolayer. The results show that as the dipole moment increases in the molecule, the surface coverage decreases. This can be the reason that a more polar molecule does not necessarily generate work function change proportionally.

Abstract

The basic concept of the use of catalysts can be studied in the course of chemical catalysts. The use of heterogeneous catalysts offers many advantages, such as: the catalyst can be easily separated from the reaction mixture without the use of solvent. Chemical catalyst can be studied through experiments of esterification reaction of waste cooking oil with methanol using heterogeneous catalyst in the process of making biodiesel. Esterification results showed that the highest conversion (83%) was obtained by metakaolin catalyst at a reaction temperature of 160 °C for 2 hours at oil to methanol ratio of 1:30.

Abstract

This paper presents a study of Rapid Visual Screening (RVS) using FEMA 154 and applied in Indonesia based on SNI 1726. RVS is a method to asses potential earthquake hazard of a building based on visual observation (“sidewalk survey”) of the exterior and interior building if possible, and a Data Collection Form. This study is intended to see how important the RVS of the FEMA 154 can be implemented in Indonesia with a case study at Yogyakarta. The buildings that reviewed were assumed to have the same parameters as mention in FEMA 154 and compatible with SNI 1726 (Indonesian earthquake map). The results from field survey were compared to the numerical analysis. From the case study, it was found that the administration building of ATK Academy, the dormitory building of Ministry of Internal Affairs, the office building of Department of Agriculture, and the educational building of Health Polytechnics have a score more than 2, and the buildings are also declared safe according to SNI 1726.

Abstract

Indonesia has high a demand level of wheat flour for both the industrial and households sectors, such as bread industry. Wheat flour is the dominant composition of bread, however it is the source of gluten which may promote celiac disease (CD). The lifetime obedience to the gluten-free diet is the only treatment for this disease. The finding of a new material in order to obtain gluten-free product is an important topic. Furthermore, Indonesia is a tropical region that is rich in natural resources, such as cassava (Manihot esculenta) and Sorghum (Sorghum-bicolor (L) Moech). Fermentation was used to improve nutritional content of sorghum flour and cassava flour, resulting modified cassava flour (mocaf) and modified sorghum flour (mosof), respectively. A strategy for utilization of cassava in production of mocaf was demonstrated. Mocaf flour can be produced by fermentation use L. plantarum, S. cereviseae, and R. oryzae that are cheap and non pathogenic to increase the levels of protein and decrease the levels of cyanide acid in the mocaf flour. This work has also shown that lactid acid is produced as by-product during the fermentation.
