Abstract

Material merupakan komponen utama dalam pembangunan infrastruktur. Kelancaran pembangunan infrastruktur ditentukan oleh ketersediaan material infrastruktur. Persediaan material infrastruktur yang berlebihan akan menimbulkan biaya persediaan yang besar. Oleh karena itu, dibutuhkan kebijakan pengendalian persediaan material infrastruktur pada PT Roberto Pratama Karya yang efisien agar dapat menghemat biaya persediaan. Dalam pengambilan varian material infrastruktur yang menjadi fokusan pada penelitian ini ditentukan oleh dua klasifikasi. Klasifikasi yang digunakan yaitu Klasifikasi ABC dan SDE (Scarce, Difficult, Easy). Klasifikasi ABC dapat mengidentifikasi material mana yang memiliki nilai besar bagi perusahaan dan Klasifikasi SDE dapat mengidentifikasi material yang memiliki lead time yang lama. Setelah mendapatkan material yang menjadi fokusan, dilanjutkan dengan perhitungan Continuous Review model (s,S) untuk mendapatkan parameter kebijakan pengendalian persediaan perbaikan. Selanjutnya dilakukan simulasi monte carlo dan dilakukan perhitungan biaya persediaan pada kondisi eksisting dan kondisi perbaikan. Dari hasil simulasi, kondisi eksisting menghasilkan biaya persediaan sebesar Rp 7,127,447,660.76 dan pada kondisi perbaikan menghasilkan biaya persediaan sebesar Rp5,362,223,861.03. Dari hasil tersebut, kondisi perbaikan memberikan penghematan pada perusahaan sebesar Rp 1,765,223,799.73 ==================================================================================================================== Material is a major component in infrastructure development. The smooth running of infrastructure development is determined by the availability of infrastructure materials. Excessive inventory of infrastructure materials will cause large inventory costs. Therefore, an efficient infrastructure material inventory control policy at PT Roberto Pratama Karya is needed in order to save on inventory costs. In taking the variant of infrastructure material which is the focus in this study, it is determined by two classifications. The classifications used are ABC and SDE (Scarce, Difficult, Easy) classifications. ABC Classification can identify which materials are of great value to the company and SDE Classification can identify materials that have a long lead time. After getting the material that is the focus, it is followed by the calculation of Continuous Review model (s,S) to be able to calculate the repair inventory control policy. Furthermore, a monte carlo simulation is performed and the inventory cost calculation is carried out in the existing and repair conditions. The inventory cost results of the two conditions are compared. From the simulation results, the existing conditions resulted in an inventory cost of Rp 7,127,447,660.76 and in the repair condition it resulted in an inventory cost of Rp 5,362,223,861.03. From these results, the repair conditions provided savings to the company of Rp 1,765,223,799.73
