Abstract

Inventori merupakan hal penting bagi perusahaan. Ketersediaan inventori dapat mempengaruhi seluruh kegiatan yang ada di perusahaan. Manajemen persediaan atau inventori mempertimbangkan semua kegiatan yang terlibat dalam perencanaan dan pengendalian tingkat persediaan bahan baku, pekerjaan dalam barang proses dan barang jadi sehingga tersedia jumlah persediaan yang cukup. Ketika persediaan bahan baku melebihi kebutuhan perusahaan, akan menambah biaya pemeliharaan dan penyimpanan serta risiko yang akan ditanggung apabila bahan baku yang disimpan menjadi rusak atau tidak layak pakai. CV. Tiga Sahabat dalam melakukan proses pengendalian persediaan masih dilakukan secara manual tanpa mempertimbangkan data historis perusahaan yang ada. Adanya jumlah pembelian persediaan yang melebihi kebutuhan perusahaan dan tidak tepat waktu, sehingga menimbulkan adanya penumpukan persediaan produk di gudang. Data historis perusahaan menunjukkan bahwa selama kurun waktu bulan April 2017 hingga November 2019, perusahaan telah melakukan 36 kali pembelian untuk produk Kabel NYM dan 25 kali untuk produk MCB. Tujuan dari penelitian ini untuk menentukan titik ROP dan EOQ, serta mencari penghematan total biaya persediaan yang dapat dilakukan menggunakan simulasi Monte Carlo. Hasil dari penelitian ini berdasarkan perhitungan ABC menghasilkan 2 produk yang diprioritaskan dalam kelas A yaitu produk Kabel NYM dan MCB dengan nilai bobot nilai index kritis sebesar 12 dan nilai penjualan masing-masing produk yaitu Rp 501.127.650 dan Rp 276.141.670. Simulasi Monte Carlo mampu menghasilkan penghematan total biaya inventori hingga Rp 117.606.080 untuk Kabel NYM dengan nilai ROP sebesar 500 meter dan EOQ 500 meter, dan total biaya inventori Rp 42.908.400 untuk MCB dengan nilai ROP 66 pcs dan EOQ 120 pcs.

Abstract

Penelitian bertujuan untuk merancangan key performance indicator untuk perusahaan ekplorasi minyak dan gas dengan mengambil studi kasus pada perusahaan minyak yang berlokasi di Langgak Oil Field, Riau dan termasuk dalam Kontraktor Kontrak Kerja Sama (KKKS) yang telah terdaftar pada SKK Migas. Pada kondisi tingkat permintaan produk utama Sumatra Crude Oil yang tinggi, manajemen atau pengelolaan proses bisnis khusus nya kinerja rantai pasok yang dijalankan harus memiliki performansi yang baik. Sebelum dilakukan penelitian ini, kinerja perusahaan didasarkan pada Key Performance Indicator (KPI) arahan SKK Migas dan perusahaan belum memiliki atribut pengukuran kinerja performansi yang baku secara internal perusahaan khususnya departemen Supply Chain Management (SCM). Pada penelitian ini, identifikasi atribut pengukuran KPI dilakukan menggunakan metode Balanced Score Card (BSC) dan Supply Chain Operation Reference (SCOR) Model 12.0. Perspektif BSC yang digunakan adalah financial, customer, learning and growth. Sedangkan perspektif internal business process dihitung menggunakan metode SCOR 12.0 berdasarkan atribut process (plan, source, deliver), dan performance (reliability, responsiveness, agility, cost, dan asset management). Hasil yang didapatkan pada penelitian ini adalah nilai kinerja performansi yang dimiliki perusahaan XYZ adalah sebesar 56,83%. Terdapat perbedaan nilai kinerja antara KPI arahan SKK Migas dengan model yang diusulkan sebesar 83,04%. Perbedaan tersebut dijadikan saran penelitian selanjutnya, terkait batasan metrik pengukuran yang digunakan. Perbaikan juga dapat dilakukan berdasarkan nilai terendah yang dimiliki, yaitu pada cost savings sebesar 16,2%

Abstract

In practice, most inventory system accommodate more than one type of item.Under this situation the analysis of inventory problem is approached by treating each type of item independently.The problem becomes complicated when constrains are imposed in inventory system.Constrains normally arise because scarce of resources exist such as capital,storage space, and equipment capacities. This paper considered a multi item inventory system with 2 constrains: working capital  and storage space restrictions.The Lagrangian method and The LIMIT technique  is utilized to obtain optimal order quantity solution for constraining conditions.While The Lagrangian method transforms a constrained optimization problem into an unconstrained  problem for higher dimension,The LIMIT Technique determines the relation of agggregate EOQ requirements to the limited resource available and revises all the lot sizes by the same proportion to bring the aggregate EOQ resources requirements within the limit. A case study of a multi item inventory system with constrains at PD Taru Martani Yogyakarta has been presented in this paper.   Keywords : multi item inventory system, constrains, the Lagrangian method, the LIMIT technique, optimal (economic) order quantity.

Abstract

Small and Medium Enterprise (SME) called MARS Genuine Leather is one of the SMEs under the guidance of the Department of Industry and Trade (Disperindag) in the Sleman region, Yogyakarta. In 2018, MARS and 10 other SMEs in Sleman and Bantul Regency have involved in research with the Department of Industrial Engineering at the Islamic University of Indonesia regarding supply chain performance analysis using the Supply Chain Operation Reference (SCOR) Model. The results showed that MARS had the lowest supply chain value among the 5 SMEs in the Sleman region. Continuing the results of the research, improvements were made through Community Service activities regarding the implementation of 5S in MARS. the Department of Industry and Trade (Disperindag) of Sleman has provided several pieces of training on the implementation of 5S for SME owners. However, this training has not been applied directly to each IKM. Therefore, this service activity aims to provide hands-on training on the implementation of 5S at IKM MARS as well as one of the improvements that can be made to the results of previous supply chain performance analysis research. The results of this service are in the form of direct training guidance at IKM, videos of the first 3S implementation (Seiri, Seiso, Seiton), and a checklist form that can be used by IKM as an internal audit. The 5S knowledge and skills that have been applied in MARS are expected to help the enterprise to reduce waste as well as increase productivity in the future.
