Abstract

CV. Bola Mas merupakan perusahaan yang bergerak di bidang vulkanisir ban. Permasalahan yang terjadi di perusahaan ini adalah sering terjadinya stock out bahan baku yang menyebabkan terjadinya keterlambatan proses produksi. Hal ini terjadi karena tidak konstannya permintaan konsumen dan inventory lead time. Tujuan  penelitian ini adalah memberikan usulan kebijakan sistem persediaan dengan model probabilistik yang dapat meminimasi keterlambatan produksi dengan biaya yang optimal.  Berdasarkan analisis ABC terdapat 2 jenis bahan baku ragi ban yang akan dikendalikan yaitu  jenis KG 1000-20 dan LG 1000-20.  Metode Trend  Projection digunakan untuk meramalkan permintaan konsumen dan mengetahui jumlah kebutuhan bahan baku yang diperlukan dalam proses produksi. Setelah membandingkan total biaya persediaan yang dihasilkan dari model probabilistik metode P dan metode Q,  maka diketahui metode Q adalah metode yang lebih optimal.  Total ekspektasi biaya persediaan Rp. 2.702.151.080,-/tahun untuk ragi ban jenis KG 1000-20 dan Rp. 1.674.652.305,-/tahun untuk ragi ban jenis LG 1000-20 .       Kata kunci: Lead Time, ABC Analysis, Peramalan, Persediaan, Probabilistik.

Abstract

CV. XYZis an industry engaged in the field of furniture producing spring bed, cabinets, buffets, chairs and others. At the spring bed assembly station, the worker assembles a springbed frame on the floor with a work position bent, squatting or sitting up to form a working posture with angles of 450 to 700 and does not use tools to support ergonomic position and posture. The purpose of this study was to design an ergonomic tools for conducted work activities on the skeleton spring bedassembly station use the RULA-REBA methods. The method of research is done by compared scores and levels before and after assembly tool design. The results show that REBA score is at 9/11 level and RULA is at 7/7 level which means that the current working condition must be improved and very unsafe for workers. After assembling the assembly tool use SolidWork software with dimension size is determined based on anthropometry data, where the height is 102 cm, length 204 cm, and width 134 cm. Then simulated use ErgoFellow 2.0 software, obtained REBA 4 and 5 score from 11 total level and RULA score is 3/7 level which means the risk of injury to worker in assembly station of skeleton of springbed can be minimized.
