Abstract

Peluru frangible memiliki kelebihan yaitu mengurangi proses ricochet (pantulan acak) dengan hancur menjadi serpihan kecil saat mengenai permukaan yang keras. Proyektil jenis ini telah dikembangkan secara luas di dunia internasional namun belum demikian di Indonesia. Maka dari itu dikembangkan peluru frangible berbahan komposit tembaga dan timah (Cu-Sn) dengan proses metalurgi serbuk. Proses metalurgi serbuk terdiri dari proses utama yaitu atomisasi, karakterisasi serbuk, pencampuran, kompaksi, dan sintering. Pabrik ini direncanakan beroperasi secara batch, 330 hari/tahun dan 24 jam/hari dengan kapasitas produksi 1.168 ton/hari. Bahan baku yang dibutuhkan sebanyak 385.605 ton/tahun. Lokasi pabrik berada di Turen- Malang, dengan bentuk perusahaan perseroan terbatas. Pendirian pabrik peluru frangible memerlukan biaya investasi modal tetap sebesar Rp41,835,134,134.03, modal kerja sebesar Rp35,559,864,013.93, biaya produksi per tahun sebesar Rp73,948,338,192.75, dan hasil penjualan per tahun Rp53,985,125,220.65. Dari analisa ekonomi didapatkan BEP sebesar 25%, ROI sesudah pajak 0.9%, POT sesudah pajak 3.38 tahun. Dari segi teknis dan ekonomis, pabrik ini layak untuk didirikan ============================================================================ Frangible bullets have an advantage that reduce ricochet (random reflection) that crumble into small pieces when it hits a hard surface. This bullet has been developed global extensively but not so in Indonesia. Now developed frangible bullet made from a composite of copper and tin (Cu-Sn) with powder metallurgy process. Powder metallurgy process consist of the main step, there are atomization, powder characterization, mixing, compacting, and sintering. This factory planned to operate with batch system, 330 days/year and 24 hours/day with production capacity are 1.168 ton/day. Raw material needed are 385.605 ton/year. The location at Turen-Malang, with corporate type is PT. Establish frangible bullet factory need fixed capital investment Rp41,835134,134.03, working capital cost Rp35,559,864,013.93, total production cost Rp73,948,338,192.75 and profit sales Rp53,985,125,220.65. From the economic analysis, BEP optained 25%, ROI after tax is 0.9%, POT after tax is 3.38 year. Based from technical and economical analysis, this plant is feasible to set
