Method refers to a measurement of naturally electric potential on the surface. Self Potential is one of thegeophysical methods that can be used to identify fluid flow in the subsurface. Finite element method hasbeen used to fluid flow velocity modeling, current source, and potential distribution modeling based onelectrokinetic effect in 2-D profile. The sign of potensial respon (negative or positive) is an important factorfor the interpretation of self-potential anomalies. Finite element method is one of the numerical methods forsolve the boundary value problems and the boundary conditions in the form of differential equations in SelfPotentialmodeling

Manufacturing companies engaged in the system of making orders are now starting to develop with increasingly diverse needs, and the business of making agricultural and food processing machinery is no exception. UD. rekayasa Wangdi W produced the machine processing manufacturing companies engaged in the make to order system are now starting to develop rapidly along with increasingly diverse needs, and the business of making agricultural and food product processing machines is no exception. UD. Wangdi W Engineering is a Make To Order (MTO) manufacturer of processing machines which currently does not consider resource capacity and order due to date as a reference for receiving orders. Even though accepting all orders does not necessarily provide maximum benefits. To help solve these problems, a decision support system design for planning the acceptance of customer orders is carried out. The system is designed using a mathematical model that was developed and modified in linear programming. The model developed has an objective function of maximizing profits from orders received and applied in the system built. The system is designed and the Mathematical Model is processed using the branch and bound method. Based on experimentation with historical data, the results obtained are only 4 slicer and 10 spinner units with a maximum profit of Rp53,115,530.00 and order completion that does not exceed the due date. Order acceptance information is displayed in tabular form and machine scheduling information is displayed in Gantt chart format

PT.XYZ merupakan perusahaan yang bergerak pada proses pengolahan karet setengah jadi (crumb rubber) yang berada pada Kota Pekanbaru. Berdasarkan observasi awal diketahui bahwa ada beberapa area produksi yang terpapar kebisingan melebihi ambang batas yang telah ditetapkan, selain kebisingan yang dirasakan operator juga masih melakukan manual material handling dengan beban satuan produk yang sangat besar. Hal ini diduga menjadi penurunan dalam kualitas kerja. Penuruan dalam kualitas kerja biasanya disebabkan karena terlalu banyaknya pekerjaan yang menggunakan kekuatan kerja fisik. Sehingga penelitian ini bertujuan untuk mengetahui apakah ada pengaruh kebisingan mesin dengan beban kerja fisik yang dirasakan oleh operator dan mengetahui faktor-faktor yang mempengaruhi denyut nadi operator terhadap kebisingan di lini produksi PT. XYZ. Metode yang dipakai pada penelitian ini adalah metode fisiologi dan uji ANOVA. Berdasarkan hasil pembahasan terdapat pengaruh antara tingkat kebisingan mesin dengan beban kerja fisik yang dirasakan oleh operator di PT.XYZ dan faktor-faktor yang mempengaruhi denyut nadi operator adalah usia, pengalaman kerja dan juga beban yang dikerjakan

In Indonesia, there are three industrial sectors with the largest number of Small Medium Enterprises (SMEs) from 2010 to 2014: food, clothing, and wood. Klastik Footwear is one of the SMEs in Indonesia that focuses on the footwear industry, especially women's shoes. Klastik Footwear brings classic and ethnic themes to its products. In order to be well received by the market, Klastik Footwear wants to identify potential consumer groups formed from market segmentation and assess the preferences of each group on Klastik Footwear products. In this study, the choice based conjoint analysis method is used to determine potential consumer preferences for Klastik Footwear products. From the results of the conjoint analysis, the importance and part-worth level of each attribute will be known. Next, a cluster and market simulator analysis is performed to see the profile of the formed segments. The results showed that there are 3 groups of potential consumers. After conducting market simulation on the three groups, it is predicted that the most ordered Klastik Footwear products by consumers are Galuh, Ara, Srikandi, and Gendhis 2 (in group 1); Brastagi, Telaga, and Gendhis 2 (in group 2); and Rinjani, Galuh, and Soko (in group 3).
