Abstract

This research aims to analyzing the MRP method to obtain the lowest inventory costs of product wine. The raw material planning system carried out by PT XYZ uses sales data from the PPIC division to order all raw materials at one time. Preparing MRP requires input in the form of an ind schedule through the netting, lotting (economic order quantity (EOQ), lot for lot (LFL)), and offsetting. The output of the MRP method is a plan for ordering raw material requirements based on lead time. This MRP method can provide improvements to PT XYZ through the formation of a master production schedule, ordering schedule, and reducing inventory costs. Comparing the company's inventory costs with the MRP method for wine raw materials produces savings of 15% per year, and EOQ is more economical. SiO2 raw material produces savings of 55% per year, and EOQ is more economical. Purifying enzyme raw materials produces savings of 41% per year, and EOQ is more economical. The MRP process is carried out at 28% annually, and EOQ is more economical. Fermented extract raw materials produce savings of 14% per year, and LFL is more economical

Abstract

Penelitian ini bertujuan mengidentifikasi kejadian risiko dan agen risiko pada rantai pasok bakery skala menengah serta menetapkan prioritas strategi mitigasi yang paling efektif dan feasible. Studi kasus tunggal menggunakan kerangka Supply Chain Operations Reference (SCOR) untuk pemetaan proses rantai pasok dan metode House of Risk (HOR) Fase 1 dan Fase 2 untuk identifikasi serta pemrioritasan risiko secara proaktif. Prosedur inter-rater reliability (IRR) diterapkan melalui Cohen's Kappa (κ) dengan dua rater independen menilai severity kejadian risiko dan occurrence agen risiko untuk menjamin objektivitas penilaian. Hasil penelitian menunjukkan 18 kejadian risiko dan 18 agen risiko teridentifikasi pada seluruh proses rantai pasok. Nilai κ rata-rata sebesar 0,871 (Almost Perfect) mengkonfirmasi validitas penilaian. Berdasarkan analisis Pareto, 10 agen risiko prioritas menyumbang 80% dari total Aggregate Risk Potential (ARP), dengan ARP tertinggi pada A13 (kurangnya ketelitian pekerja, ARP = 2.023). HOR Fase 2 menghasilkan 10 strategi mitigasi dengan pembentukan divisi Quality Control sebagai prioritas tertinggi (ETD = 6.069). Penelitian ini menyimpulkan bahwa integrasi SCOR, HOR, dan validasi IRR berbasis Cohen's Kappa menghasilkan kerangka manajemen risiko rantai pasok proaktif yang lebih valid dan operasional bagi UMKM bakery, sekaligus mengisi celah metodologis pada studi HOR sebelumnya.
