Abstract

SK JAYA adalah perusahaan manufaktur lokal yang sudah berproduksi secara komersial dan memiliki beberapa kegiatan usaha yaitu perdagangan panel-panel listrik, Box metal. Namun, dalam melakukan perencanaan dan pengendalian bahan baku, perusahaan mengalami kendala karena belum dilakukannya suatu perencanaan yang tepat dalam menentukan kebutuhan bahan baku. Kendala ini tentunya berpengaruh terhadap proses produksi dan pengelolahan biaya dalam melakukan pengadaan bahan baku. Untuk Box Panel, dengan metode perusahaan yang diterapkan sebelumnya, perusahaan hanya mampu memenuhi kebutuhan sebesar 2.880 pcs sedangkan kebutuhan yang dibutuhkan sebesar 3.150 pcs. Untuk membantu masalah yang terjadi pada CV. SK JAYA, maka diterapkan suatu metode Material Requirement Planning (MRP) yang dapat membantu perusahaan dalam melakukan perencanaan bahan baku secara tepat. Dengan menggunakan metode MRP, perusahaan mampu menentukan kebutuhan yang dibutuhkan untuk melakukan suatu proses produksi dengan biaya yang efisien. Bahan baku yang dikeluarkan perusahaan dalam melakukan pengadaan bahan baku selama satu tahun plat besi untuk komponen pintu box, bagian belakang box, samping box, bagian bawah box, dan kepala box membutuhkan sebanyak 3.147 lembar plat besi , komponen kunci membutuhkan 3.048 pcs, komponen tombol membutuhkan 9.441 pcs, komponen plat nama membutuhkan 2.081 pcs , komponen ensel membutuhkan 3.048 set, komponen BG lubang kabel membutuhkan 3.048 pcs. Dengan teknik Fixed Periode Requirement (FPR) mendapatkan biaya sebesar Rp6.659.790,00. Hal ini membuktikan bahwa penerapan metode MRP dapat berperan dalam melakukan perbaikan perencanaan dan pengendalian bahan baku dengan biaya yang efisien pada perusahaan.

Abstract

Dams are hydraulic structures designed to store water or retain sediment and mud. Although they provide significant benefits, they also involve substantial risks and require considerable financial investment. The selection of an appropriate dam type for a specific location must be based on a comprehensive evaluation of feasible dam alternatives, considering various factors, including topography, hydrology, foundation geology, economic feasibility, social conditions, and environmental impacts. Since selecting a dam site and type involves multiple criteria, an appropriate multicriteria decision-making approach is necessary. Currently, Multi-Criteria Decision-Making (MCDM) methods have been widely applied to assess dam construction priorities, particularly in determining the most suitable dam sites and types. This study employs a hybrid multicriteria decision-making approach integrating the Delphi method, the Analytic Hierarchy Process (AHP), and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Primary data were collected through questionnaires administered to experts from various institutions with relevant knowledge and experience in dam engineering and construction. The Delphi method was used to screen and refine the criteria, subcriteria, and sub-subcriteria, while the Kruskal–Wallis test was applied to assess differences in expert assessments. The results of the AHP analysis indicate that environmental factors are the most influential criteria in selecting suitable dam sites and types.
