Abstract

Spare part mesin produksi merupakan salah satu komponen pendukung yang memegang peranan penting bagi kelangsungan produksi di PT. X. Sehingga pengendalian persediaan spare part mesin produksi merupakan fokusan utama dalam hal ini. Permasalahan yang dihadapi oleh perusahaan seringkali terjadi kelebihan dalam melakukan persediaan spare part mesin produksi, sehingga dalam hal ini dapat menimbulkan biaya persediaan yang tinggi. Pengendalian persediaan yang dihitung merupakan lima teratas spare part mesin produksi yang terpilih dari setiap kelas pada klasifikasi ABC. Adapun strategi pengendalian persediaan spare part mesin produksi dalam penelitian ini dikelompokkan berdasarkan perhitungan ADI dengan lead time pemesanan dan perhitungan VC. Dari hasil pengelompokan tersebut maka didapatkan strategi pengendalian persediaan yang tepat apakah termasuk ke dalam continuous review (s,S), periodic review (R,s,S), ataupun MRP. Pada Penelitian ini hanya menggunakan metode pendekatan continuous review (s,S) dan periodic review (R,s,S) yang kemudian dilakukan Simulasi Monte Carlo untuk mendapatkan performansi dari kebijakan persediaan awal dan perbaikan. Performansi yang diamati yaitu jumlah inventory sisa, jumlah stock out, total biaya persediaan, dan service level. Hasil perbandingan total biaya persediaan antara kondisi perbaikan dengan kondisi awal perusahaan mengindikasi adanya penghematan sebesar 30%.

Spare parts of production machines are one of the supporting components that play an important role for the continuity of production at PT. X. So that, the control of spare part of production machines inventory are the main focus in this research. Problems faced by companies often occur excess in doing spare parts of production machines inventory, so that in this case can cause high inventory costs. Inventory control calculated is the top five spare parts of production machines selected from each class in the ABC classification. The strategy of spare part of production machines inventory control in this research is grouped based on ADI calculation with ordering lead time and VC calculation. From the results of the grouping, the right inventory control strategy is obtained is it included in continuous review, periodic review, or MRP. This research only uses a continuous review and periodic review approach which is then carried out in a Monte Carlo Simulation to obtain performance from the initial inventory policy and improvement. The performance observed are residual inventory, stock out, total inventory costs, and service level. The results of the comparison of total inventory costs between the condition of repairs and the initial conditions of the company indicate a savings of 30%.
