Abstract

Andaliman is a typical seasoning plant of Sumatra which can be used as a flavouring traditional Batak (arsik) and other derivative products such as crackers, bandrek which have a taste of andaliman. One process that is passed so that Andaliman can be used as a seasoning and other product is drying process. Generally, andaliman drying is done by solar power or dryer. The current condition at the UMKM of Taman Eden 100 is the length of time of drying and limited capacity so that it is unable to meet the demand of arsik instant flavor. This research was conducted by applying the Quality Function Deployment (QFD) method through a questionnaire distributed to owners and workers at the UMKM to determine the desirable desiccant needs. The results of the QFD are mapped into the House of Quality which is expected to be a picture of the new dryer. From this HOQ, it is produced that the user wants a dryer with a larger capacity than before which has a heat control device so that the heat is evenly distributed in the drying chamber. The aroma of andaliman also remains even though the water content in dry andaliman has decreased.

Abstract

Daerah penelitian (PT NAL) terletak di Desa Salak, Kecamatan Talawi, Kota Sawahlunto. Tujuan penelitian ini adalah untuk menganalisis kuat tekan batuan dan waktu stand-up yang diperlukan dalam perencanaan penggalian dan pemasangan dukungan penambangan bawah tanah di PT. NAL. Pengumpulan data dalam penelitian ini menggunakan observasi lapangan dan pengujian laboratorium. Metode pemecahan masalah dalam penelitian ini didasarkan pada klasifikasi massa batuan dari Bienalwski (1973) Sistem Nilai Massal Batu atau RMR yang terdiri dari kekuatan tekan UCS, jarak diskontinuitas, Rock Quality Designation (RQD), kondisi solid, kondisi air tanah dan orientasi pemegatan. Hasil analisis kekuatan uji kuat tekan batuan utuh, terlihat bahwa batuan terowongan memiliki nilai UCS 8,835 Mpa (lemah) untuk batu pasir, 13.367 Mpa (lemah) untuk batu lanau dan 4,620 Mpa (sangat lemah) untuk batubara. Berdasarkan sifat fisik, diketahui bahwa setiap batuan memiliki nilai porositas yang rendah. Analisis geomekanik memberikan nilai tertimbang Rock Mass Rating (RMR) dengan kualitas massa batuan kelas II (rock baik) untuk tiga jenis massa batuan. Analisis menggunakan grafik waktu stand-up, lamanya batu dapat menahan self-stress tanpa stand-up time untuk batupasir ± 2500 jam (3 bulan 12 hari) dengan bentang 8 m, batu lanau ± 2000 jam (2 bulan 21 hari ) dengan bentang 8 m dan batu bara ± 5000 jam (6 bulan 27 hari) dengan rentang 6,8 m.

Abstract

Archive is defined as a place to storage important scripts or documents. In general, archive is a form of  writing in form of document in any media that has a historical value or liability so that can be stored. Manual letter archive system and not systematic report logs cause searching the document difficult and time-consuming. Therefore, it is necessary to design an application to help the head of the study program in search of reports of letters in and out.

Abstract

PT. Coca Cola Amatil Indonesia (CCAI) is a company engaged in the manufacture of soft drinks agro-industry. In the process of production of PT. CCAI has decreased the amount of production in 2013. To overcome this problem, researchers interested in more depth about the function of the simplex method for optimal production quantities and the maximum income that can be obtained by PT. CCAI.Simplex method is a method of solving problems through recalculation linear program (iteration) which measures the same calculation is repeated many times before the optimum solution is achieved. Simplex method is used to solve the case with many decision variables. In this study, the calculation of the simplex method using software lingo10, variable objective function simplex method in this study is the selling price of the product, raw material concentrates, sugar raw materials, raw materials and raw materials CO2 syrup. From the calculations have been done obtained optimal production quantities which produces Coca Cola 295ml many as 440547.8 crates / year, as many as 44604.35 crates Sprite 295ml / 220ml Frestea year and as many as 464847.8 crates / year so thatthe maximum income to be obtained by the company amounted to USD 2.235097 billion.Keywords: production, simplex method, revenue, software lingo10
