Abstract
PT Framas Indonesia merupakan perusahaan manufaktur industri injeksi plastik dengan konsentrasi produksi outsole yang menerapkan konsep make-to-order (MTO) non-repetitve. Dengan diterapkannya konsep produksi MTO, persediaan menjadi hal yang sangat penting untuk kelancaran produktivitas dalam memenuhi kebutuhan konsumen sesuai dengan estimasi waktu pengiriman. Namun setelah di analisa lebih dalam terdapat permasalahan dalam ranah supply chain yang berakibat pada persediaan pigments yang dirasa masih ada kekurangan dalam flow process pengadaannya. Jika terus dibiarkan hal ini dapat mengakibatkan meningkatnya biaya yang akan dikeluarkan oleh perusahaan. Dampak dari permasalahan tersebut adalah terjadinya down-time machine akibat dari keterlambatan kedatangan pigment dengan total 30,171 menit dan overstock dengan total inventori sebesar 7.913,38 kg dengan inventori aset sebesar $ 165.079,92. Tujuan dari penelitian ini yaitu mengidentifikasi, analisis dan merancang strategi replenishment persediaan pigments yang bekerja sama dengan pemasok untuk mengantisipasi permintaan tidak pasti. Dari hasil analisis ditemukan bahwa model persediaan bersifat stokastik dengan pola demand yang tidak dapat diprediksi sehingga diperlukan kebijakan sistem replenishment yang baik dalam penanganannya. Hasil akhir dari penelitian ini yaitu ditetapkannya strategi replenishment persediaan pigment dengan integrasi antara metode hybrid MRP-JIT dengan kebijakan yang ditentukan agar mempermudah dalam pelaksanaannya. Sehingga MRP dapat memperbaiki proses persediaan dari segi perencanaan dan JIT mempercepat proses persediaan dalam segi pelaksanaan operasional di lapangan dibantu dengan metode supplier Kanban. Penelitian ini mengarah pada cost efficiency yaitu dengan berkurangnya inventory level, total down-time machine diakibatkan karena keterlambatan kedatangan pigment dan overstock yang mengakibatkan non-moving stock pada persediaan pigment. ===================================================================================================== PT Framas Indonesia is a plastic injection manufacturing company with an outsole production concentration that applies the concept of make-to-order (MTO) non-repetitve. With the application of the MTO production concept, inventory becomes very important for smooth productivity to meet consumer needs in accordance with estimated delivery time. However, after a deeper analysis, there were problems in the realm of the supply chain which resulted in pigments that were felt to be still lacking in the procurement process flow. If it continues to be left this can result in increased costs to be incurred by the company. The impact of these problem is the occurrence of a downtime machine due to the lateness of the pigment with a total of 30.171 minutes and an overstock total inventory of 7,913.38 kg with an asset inventory of $ 165,079.92. The purpose of this study is to identify, analyze and design a replenishment strategy for pigments supplies in collaboration with suppliers to anticipate uncertain demand. From the analysis, it is found that the inventory model is stochastic with unpredictable demand patterns, so a good replenishment system policy is needed in its handling. The final result of this research is the determination of the pigment inventory replenishment strategy with the integration between the MRP-JIT hybrid method and the determined policies in order to facilitate its implementation. So that MRP can improve the inventory process in terms of planning and JIT accelerates the inventory process in terms of operational implementation in the field-assisted by the Kanban supplier method. This research aims at cost efficiency, namely by reducing inventory levels, the total downtime of the machine is caused by delays in the arrival of pigments and overstocks which results in non-moving stock in the pigment inventory.
