Perencanaan Kebutuhan Material Untuk Produk Disposable Protective Mask Selama Pandemi Covid 19 Di Kota Malang

Abstract

Tahun 2020 adalah tahun yang berat bagi semua orang karena adanya pandemi COVID-19 yang mengharuskan setiap orang untuk menggunakan masker untuk melindungi diri dari sebaran virus ini. Hal ini tentunya berdampak bagi perusahaan yang memproduksi masker khususnya perusahaan X, karena jumlah permintaan naik secara significant. Untuk mengatasi permasalahan ini, kita menggunakan metode demand forecasting dan MRP dari data historis jumlah penduduk kota malang. Dengan menggunakan metode ini kita akan mendapatkan hasil bahwa perusahaan X mempunyai jadwal produksi pada periode pertama yaitu pembuatan nose bridge wire sebanyak 5.200.000 unit, pembelian non-woven putih dan melth blown cloth masing-masing sebanyak 1.545.730.000 cm2, dan pembelian non-woven biru sebanyak 1.675.410.000 cm2, sedangkan pada periode kedua pembelian tali elastis sebanyak 165.990.000 cm, periode ketiga pembuatan masker sebanyak 5.187.008 unit dan pada periode keempat pembuatan disposable protective mask sebanyak 5.187.008 unit.

Raw Material Planning and Control with MRP Method to Maintain Accurate Production Amounts in UKM Allwooden Woodworking

“…Accurate forecast result has several important criteria, namely: The accuracy of a forecasting result is measured by the results of the habit and the consistency of the forecast. [10] C. Material Requirement Planning Material Requirement Planning or MRP is a technique or tool for determining the right material requirements by using several input data such as a list of raw material requirements, inventory data, receiving schedules, and master production schedules. Meanwhile, according to [10], MRP is one of the concepts for planning the requirements of the right goods in the production process.…”

“…The purpose of MRP is to reduce inventory, reduce lead times, deliver on time, and improve production system efficiency. In addition, the purpose of using the MRP method is to find the right way to regulate product requirements in the production process according to needs so that the required products can be fulfilled on time [10]. So, it can be concluded that MRP is a technique for planning and scheduling raw materials used for the production process according to material requirements, inventories, estimated receipts, and production schedules.…”
