Abstract

Mengelola dan mengendalikan persediaan spare parts di industri termasuk industri semen adalah kegiatan penting yang dilakukan oleh manajer inventory. Dalam studi kasus, insiden kehabisan stok terutama suku cadang dalam kategori listrik dan instrumentasi sering terjadi dan secara signifikan mempengaruhi program pemeliharaan berdasarkan pada pengamatan dan pengumpulan data awal. Tujuan dari penelitian ini adalah untuk menyelidiki dan menganalisis persediaan spare parts menggunakan metode yang sesuai. Fenomena lumpy demand terjadi di beberapa spare parts berdasarkan metode matriks ADI-CV dan metode probabilistik diperlukan untuk mengelola spare parts dengan fenomena tersebut. Kebijakan metode continuous review (s, S) dipilih untuk menentukan jumlah kuantitas pemesanan, titik pemesanan ulang (ROP) dan total biaya persediaan. Metode simulasi Monte Carlo digunakan untuk menganalisis kinerja persediaan seperti biaya persediaan dan service level. Hasil utama dari penelitian ini adalah untuk menentukan tindakan perbaikan untuk material dalam rangka mengurangi stock out dan biaya persediaan. Berdasarkan hasil perhitungan pengendalian persediaan spare part di industri semen dengan metode continuous review didapatkan hasil nilai service level yang lebih tinggi dibandingkan kondisi existing. Implikasi praktisnya bagi perusahaan salah satunya adalah penelitian ini dapat dipakai untuk memasukkan data klasifikasi material (A/B/C) pada sistem SAP perusahaan, mengurangi shortage spare part sehingga durasi perbaikan peralatan dapat dikurangi dan juga dapat mengurangi indeks pemakaian listrik. ========================================================================================= Managing and controlling the spare parts inventory in industries including cement industries is critical activities that was conducted by inventory manager. In case study, the out of stock incidents especially spare parts in the electrical and instrumentation category were often occurring and significantly affecting the maintenance program based on observation and preliminary collection data. The purpose of this study is to investigate and analysis spare parts inventory using the appropriate methods. The lumpy phenomena was happen in some spare parts based on ADI-CV matrix methods and the probabilistic methods is needed to manage spare parts. The continuous review method (s, S) policy is selected to determine order quantity, reorder point (ROP) and total inventory costs. The Monte Carlo simulation method is used to analysis the inventory performance such as inventory costs and service level. The main results of this study is to determine the improvement action for managerial in order to reduce stock out and inventory costs. Based on the calculation of spare part inventory control in the cement industry using continuous review method, the service level value obtained is higher than the existing conditions. Practical implication for the company is that this research can be used to identify material classification data (A/B/C) in the compny’s SAP system. Otherwise it can minimize shortage of spare part so it can reduce equipment repairs time and also can reduce the electricity usage index.
