So the request is not based on the calculation of carbon brush needs for electricity production with investment costs. Based on the history of usage and carbon brush supplies in 2015 are stored in the warehouse of carbon brush as many as 149 units with an inventory&nbsp; value of Rp &nbsp;219.402.500. It is therefore necessary planning &nbsp;and inventory control carbon brush is optimal based on the pattern data when replacing the carbon brush with a way to test the suitability of the failure distribution, calculate the expected demand of carbon brush, specify the&nbsp; number of economic order quantity, reorder point, expected demand for lead time, safety stock, and total cost of inventory. With &nbsp;Minitab &nbsp;software &nbsp;using &nbsp;analysis &nbsp;goodness&nbsp; of &nbsp;fit &nbsp;Anderson-Darling &nbsp;Test &nbsp;results obtained by testing the data distribution has a failure distribution pattern weibull. From the calculation of the inventory of carbon brush with a sample calculation 1 generator for the time inventory planning 180 days result expectations required demand of carbon brush 70 units, the number of economic order quantity 31 units, reorder point 22 units, expectations &nbsp;demand &nbsp;for&nbsp; a &nbsp;lead &nbsp;time &nbsp;of &nbsp;12 &nbsp;units, &nbsp;safety &nbsp;stock 10 &nbsp;units, and &nbsp;total inventory cost Rp. 4.187.397.</em></p> Muhamad Rosie Friansyah Nur Yulianti Hidayah Copyright (c) 2018 Jurnal Sistem Industri : Jurnal Keilmuan Teknik & Manajemen Industri 2018-11-03 2018-11-03 11 2 77 86 PERAN ENTREPRENEUR ORIENTATION TERHADAP VOLATILITAS USAHA KECIL DAN MENENGAH DENGAN MEDIASI BUDAYA LOKAL DI JABODETABEK https://teknik.univpancasila.ac.id/industri/jsi/index.php/12345/article/view/187 <p><em>This research aim is to find growth strategy of small and medium enterprises (SME) oriented with entrepreneurship by looking at enterpises’ growth and sales based on the ethical discernment of the local culture of SME.

Ini berarti bahwa menghasilkan produk yang berkualitas dengan&nbsp;&nbsp; harga yang kompetitif menjadi satu tantangan yang harus mampu ditaklukkan oleh pelaku usaha dewasa ini.</p> <p>&nbsp;Produk atau jasa yang berkualitas adalah yang memenuhi atau melebihi harapan pelanggan dalam delapan dimensi sesuai dengan kriteria Garvin berikut, yaitu : (1) kinerja, (2) estetika, (3) kemudahan perawatan dan perbaikan,(4) fitur, (5) keandalan, (6) tahan lama, (7) kualitaskesesuaian, dan (8) kecocokan penggunaan.</p> <p>&nbsp;Biaya kualitas adalah biaya-biaya yang muncul disebabkan karena produk yang buruk kualitasnya. Definisi ini mengimplikasikan bahwa biaya kualitas berhubungan dengan dua kategori dari kegiatan-kegiatan yang terkait dengan kualitas, yaitu : kegiatan pengendalian&nbsp; dan&nbsp; kegiatan&nbsp; karena &nbsp;kegagalan.&nbsp; Kegiatan &nbsp;pengendalian&nbsp; dilakukan&nbsp; oleh suatu perusahaan untuk mencegah atau mendeteksi kualitas yang buruk. Sedangkan kegiatan karena kegagalan dilakukan oleh perusahaan atau oleh pelanggannya untuk merespon kualitas yang buruk. Feiganbaum mendefinisikan kegiatan-kegiatan yang berhubungan dengan kualitas dengan membaginya menjadi&nbsp; &nbsp;empat kategori biaya kualitas, yaitu: (1) biaya pencegahan (<em>Prevention Cost</em>), (2) biaya penilaian (<em>Appraisal Cost</em>), (3) biaya kegagalan internal (<em>Internal Failure Cost</em>), dan (4) biaya kegagalan eksternal (<em>External Failure cost</em>). Biaya pencegahan terjadi untuk mencegah kualitas yang buruk pada produk atau jasa yang dihasilkan. Sejalan dengan peningkatan biaya pencegahan, diharapkan biaya kegagalan turun.</p> <p>&nbsp;Yang&nbsp;&nbsp; (2008) mengklasifikasikan total manufacturing cost menjadi 33 komponen biaya dalam 5 klasifikasi biaya perencanaan produk baru, pengembangan produk dan desain, usaha memperoleh dan memeriksa kualitas barang yang baru datang, manufaktur proses dan penjulan dan layanan konsumen. Dahlgaard dan Dahlgaard (2002) membahas evolusi biaya kualitas, dari inspeksi dan pengurangan cacat total menuju filosofi manajemen mutu baru, yaitu klasifikasi baru biaya kualitas dengan membuat perbedaan yang lebih jelas antara biaya yang terlihat dan unsur-unsur biaya individu. Permasalahan dalam penelitian ini adalah menggabungkan dua model yaitu model total biaya manufaktur yang dikembangkan oleh Yang&nbsp;&nbsp; dan model yang dikembang oleh Dahlgaard dan Dahlgaard dengan evolusi pengembangan model biaya kualitas.</p> Rida Norina Hermita Dyah Puspita Copyright (c) 2018 Jurnal Sistem Industri : Jurnal Keilmuan Teknik & Manajemen Industri 2018-11-03 2018-11-03 11 2 99 116 PENGENDALIAN PRODUK PRIORITAS DENGAN METODA SIMULASI MONTE CARLO PADA AREA FINISH GOODS DI PT.

TAISHO PHARMACEUTICAL INDONESIA TBK https://teknik.univpancasila.ac.id/industri/jsi/index.php/12345/article/view/193 <p><em>The high down time, especially in the production will result in the low value of the effectiveness of a machine. PT. Taisho Pharmaceutical Indonesia manufactures Counterpain, Tempra and Diamond products, where for the company's Tempra product is not able to meet market demand caused by the low of OEE value for 5 months from August 2016 until December 2016 an average of 81,04%. Company at least 85%. As a result the company will experience loss. This study aims to determine the time down time, know the value of OEE, determine the root cause, know the dominant cause factors the high down time and provide action plans to reduce the high time set up and change over. Data collection is done by field method and literature study. Field method is done by observation, interview to production operators, employees, and documentation. In this research, collecting data of production process per week, calculating available rate, performance rate, quality rate, and OEE value. Then, identify the cause of the problem with the ishikawa diagram and trace the cause of failure with FMEA. The results of this study is the high down time will affect the value of the effectiveness of the machine. The analysis is done by looking at the value of Overall Equipment Effectiveness done by processing the production data. Efforts that can be done to reduce down time is to reduce change over time and set up, make SOP, division of tasks between operator and helper. To meet the needs of consumers, the company must make timely production, among others by reducing down time.</em></p> Sambas Sundana Slamet Riyanto Copyright (c) 2018 Jurnal Sistem Industri : Jurnal Keilmuan Teknik & Manajemen Industri 2018-11-03 2018-11-03 11 2 167 176 ANALISIS KEKUATAN KERANGKA MESIN PENGUPAS LIMBAH KABEL MENGGUNAKAN CAE PADA SOFTWARE PRO-ENGINEERING https://teknik.univpancasila.ac.id/industri/jsi/index.php/12345/article/view/194 <p><em>The rapid growth of waste causes adverse impacts on the environment therefore a good processing effort is required.

Therefore it is necessary to create an environmentally friendly cable peeler machine, so that the machine can be used properly and safely it is necessary to analyze the engine framework. The results of the analysis using pro-engineering software found that the engine framework is safe because Von Mises stress produced 5.4 MPa smaller than the yield strength of steel used is ST37 of 105 MPa is supported also with the value of strain of 0.00016 N / mm2 occurred at the distance 100 mm, displacement that occurs relatively small that is 0.13mm.</em></p> Yani Kurniawan Bambang Cahyadi Copyright (c) 2018 Jurnal Sistem Industri : Jurnal Keilmuan Teknik & Manajemen Industri 2018-11-03 2018-11-03 11 2 177 180
