Optimasi Ukuran Close Side Setting (Css) Jaw Crusher untuk Meningkatkan Produksi Jaw Crusher pada Tambang Andesit Di PT Mandiri Sejahtera Sentra (MSS).
Abstract. PT Mandiri Sejahtera Sentra (PT MSS) is a private mining company that extracts andesite rock, located in Sukamulya Village, Purwakarta Regency, West Java. The mining area covers 41. 19 Ha, and the company aimed for a production target of 470 tonnes per hour using jaw crusher equipment. However, it has not met this target, partly due to the suboptimal close side setting (CSS) of the jaw crusher. To address this, the company experimented with three variations of the CSS to find the optimal size that meets production goals without hindering the cone crusher’s operation. After optimizing, the recommended CSS size is 185 mm. At this setting, the production reached 475. 554 tonnes per hour, surpassing the initial target, with an average stone size of 132. 2 mm for further processing. Abstrak. PT Mandiri Sejahtera Sentra (PT MSS) adalah perusahaan swasta yang memproduksi batu andesit dan terletak di Desa Sukamulya, Purwakarta, Jawa Barat. Area penambangan perusahaan seluas 41,19 Ha, dengan target produksi 470 ton/jam menggunakan jaw crusher. Target ini tidak tercapai, kemungkinan karena pengaturan close side setting (CSS) yang kurang baik. Percobaan optimasi dilakukan dengan tiga variasi ukuran CSS: 175 mm, 185 mm, dan 195 mm. Penelitian dilakukan untuk menemukan ukuran CSS optimal yang dapat memenuhi target produksi tanpa menghambat proses berikutnya menggunakan cone crusher. Setelah optimasi, disarankan menggunakan CSS 185 mm, yang mencapai produksi 475,554 ton/jam, melebihi target 470 ton/jam, dengan ukuran produk rata-rata 132,2 mm.
