This research has been conducted on the geothermal area of Arjuno-Welirang, the with aim to know the alteration of rocks based on their mineralogical properties. The method used is X-ray Diffraction by using Shimadzu X-ray Diffraction technique, Co-Kɒ radiation (ɒ = 1.54060 Å). Mineral phase obtained from Padusan rock samples are 9 minerals ie Aragonite and followed by other minor phases. Then on Cangar rock samples, there are 7 mineral phases with core minerals, ie Silicon Oxide and followed by phase of other minerals.

Peanuts or Latin Arachis hypoghea is one of the crops of palawija that has long been known to our farmers as a production plant. One of the causes that inhibits peanut productivity is because the planting process is still done manually using human power. To overcome this, the system was designed to design a tool for planting peanuts mechanically. The design of this equipment begins with the size and shape of the instrument itself with the aim of producing a peanut plant that works in human thrust strength, this study brings significance to farmers to save costs to pay workers, otherwise farmers work efficiently and effectively.

Steel as one of construction materials has several advantages compared to other construction materials. One of the advantages is it can withstand large tensile loads compared to wood and concrete. This research was conducted to find out the strength of the connection of two-faced steel plate tension member with bolts connection through experiment and compare it with theoretical calculations by using Allowable Stress Design (ASD) method. The focused structure is a two-faced connection tension member that is connected using bolts. Steel plated that used in this research are 8 mm and 10 mm thickness with bolt sizes Ø ¼ ", Ø 3/8" and Ø ½ ", each connection using three bolts as connector. The testing of the tension member connections in the laboratory is carried out by gradually loading the tensile load until the tensile member reaches the ultimate load. The results of experimental and theoretical research found that theoretical calculation of tensile strength smaller than tensile strength done experimentally.

Bulletproof vests are outer clothing commonly used to protect military personnel from projectile attacks and explosion material distributions. In this study the bulletproof vests were made of composite particles composed of an epoxy matrix with a Hollow Glass Microsphere (HGM) amplifier and carbon fiber. The study was conducted by doing simulation analysis using Finite Element Method in accordance with NIJ (National Institute of Justice) of American Standard 0101.06 for class IIIA weapons category. The thickness of bulletproof vest was varied from 1 to 20 mm in order to obtain the optimal thickness. After obtaining optimal thickness of the bulletproof vest, then verification with experimental will be done to validate the simulation result. The results showed that the increase in the thickness has increase the toughness and rigidity of a bulletproof vest. A bulletproof vest with a thickness of 20 mm able to absorb bullet energy of 348.27 Joule and kinetic energy which passed the body of 138, 77 Joule with a penetration depth of 5.54 mm. Thus, it has met the NIJ Standard 0101.06 standard of U.S. The energy passed to the body is smaller than 170 Joule.

Seleksi Beasiswa Untuk Perguruan Tinggi Berdasarkan Pendekatan Keputusan Berkeadilan dengan Fuzzy Mamdani Amsar Amsar; Rizal Munadi; Ramzi Adriman

The scholarship is one of the funding schemes of study in an education system. Various models and names of scholarship schemes are offered on terms that have been determined by the scholarship provider. The essence of these conditions is the trust and confidence of the funders of the scholarship recipients and is projected to complete the study period as per the allocated funds. In general, funders are very concerned about the issue of academic qualification as one of the main indicators. However, for prospective students who wish to pursue higher education from coming from orphaned families and from less financially qualified families, with good academic qualifications, not yet a parameter in the selection process of scholarship recipients. Based on this fact, this problem would like to find solution in this research and submitted the selection model of scholarship with fair decision approach. This study aims to design a fair decision-making system as a tool for selection of scholarship recipients that prioritize the values of justice by prioritizing scholarship recipients from among orphans and poor. This research proposes two methods: Fuzzy Mamdani and weighting method, with 4 input parameters which are used as variables: children status and economic level, residence condition, children achievement and family dependent. Simulation testing performed by considering the parameters set is a more effective and efficient decision model for the prospective scholarship recipients. To obtain a competent recipient, then the screening process by ranking to be declared passed the selection and received as the recipient of scholarship in accordance with the number of quotas provided. This selection model becomes an alternative and provides opportunities for orphans and the poor to continue higher education and improve the human resource index as well as meet national education goals.

Pembuatan Sistem Informasi Geografis Untuk Pemetaan Sebaran Lokasi Distribusi Pemasaran Produk Batu Marmer Politeknik Aceh Selatan Safridatul Audah; Bakruddin Bakruddin

South Aceh Regency has abundant mine products, one of which is marble. Polytechnic of South Aceh Particularly UPT Marmer Industrial Engineering Study Program performs processing of marble in the form of marble processed into the form of crafts, such as tables, chairs, glasses, ashtrays, and so on, and spread in various areas that have been distributed, but the marketing of marble production not all is known by the community, so it is necessary to find a solution to be able to mapping the location of marble marketing in order to increase production output to be distributed to the consumer of various regions. This research is expected to produce Geographic Information System for mapping of marketing location of marble production of Polytechnic of South Aceh so that society can know marble marketing center in Aceh region.

Mathematical Modeling of SEIR Type to Controlling Diabetes Mellitus Disease Using Insulin Asmaidi Asmaidi; Eka Dodi Suryanto

Publisher : LPPM Politeknik Aceh Selatan

In this research the developed model is SEIR type mathematical modeling using insulin as a form of treatment. SEIR is abbreviation of susceptible (S), exposed (E), infected (I) and recovered (R). Expected goals include to making mathematical models for spread of diabetes mellitus, fixed point determination and basic reproduction number, stability analysis of fixed point, simulation of fixed point stability, simulation of population behavior to know the strategy of controlling diabetes mellitus. Analytical and numerical analysis results were obtained two fixed points, namely the point of no disease (disease-free equilibrium) and the point of disease (endemic equilibrium). Stability analysis of each fixed point indicates that the fixed point there is no stable disease when R0 < 1, whereas the fixed point there is stable disease when R0 > 1. Numerical simulations show that, with reduced Susceptible population contact rate with the exposed population causing to decrease, so the spread of the disease does not appear in the population. These results indicate that one strategy of controlling the spread of diabetes mellitus can be done by reducing the rate of contact susceptible population with eksposed.
