Abstract
ABSTRAK Proses penelitian ini dilakukan di Perusahaan Refraktori. Material yang diproduksi adalah pasir krom. Salah satu mesin yang digunakan pada proses produksi pasir krom adalah mesin Magnetic Separator. Berdasarkan data produksi pada periode Juli – Desember 2019 didapatkan mesin Magnetic Separator hanya dapat mencapai volume produksi sebesar 93.32% dari target produksi yang telah ditetapkan. Oleh karena itu, dilakukan proses analisis dengan menggunakan Diagram Pareto, perhitungan Overall Equipment Effectiveness (OEE) dan Six Big Losses. Untuk mengetahui penyebab target produksi yang tidak tercapai dilakukan menggunakan metode 5 Whys Analysis. Kemudian dari hasil analisis tersebut diketahui bahwa penyebab terjadinya target produksi tidak tercapai adalah breakdown mesin yang tinggi dikarenakan kurangnya pengalaman operator, poros bucket yang tidak align karena terdapat part pada mesin yang telah aus, flow material terlalu besar, proses inspeksi kurang menyeluruh, dan debu yang menyumbat part. Setelah dilakukan perbaikan didapatkan hasil nilai OEE meningkat sebesar 8.70% yaitu sebelum perbaikan rata-rata nilai OEE adalah sebesar 75.83% kemudian setelah perbaikan sebesar 84.53%. Kata kunci :Magnetic Separator, Overall Equipment Effectiveness (OEE) ,pasir krom, Pareto Diagram, Six Big Losses , 5 Whys Analysis. ABSTRACT This research is done in Refractory Company. Material that produced in this company is chromite sand. One of machine that used in production process is Magnetic Separator. Based on production report in period July - December 2019 known that Magnetic Separator only can achieve 93.32% production volume form the production target. Therefore the analyzing process is done by using Pareto Diagram, Overall Equipment Effectiveness (OEE) and Six Big Losses calculation. The cause of unachieved target is searched by using 5 Whys Analysis method. Then, based on analyzing process known that the cause of unachieved production target is high intensity of machine breakdown. It’s caused by less skill of operator, misalign of bucket shaft because of a worn out part of machine, too big material flow, incomplete inspection process, and dust that plug up the part. After solve the problem we get OEE value increase about 8.70%, form 75.83% to 84.53%. Keywords : Magnetic Separator, Overall Equipment Effectiveness (OEE), chromite sand, Pareto Diagram, Six Big Losses , 5 Whys Analysis.
