Abstract
Persediaan merupakan hal yang sangat penting untuk perencanaan produksi. Oleh karena itu, setiap perusahaan harus memiliki perencanaan yang baik karena apabila persediaan dilakukan dalam jumlah yang terlalu besar maka akan menyebabkan kerugian. Begitupun sebaliknya bila persediaan terlalu kecil akan mengakibatkan penekanan pada keuntungan. Pada penelitian ini akan digunakan gabungan metode Economic Production Quantity (EPQ) Multi-items dan Goal Programming. Metode Economic Production Quantity (EPQ) Multi-items digunakan untuk menentukan jumlah produksi optimal dan total biaya persediaan optimal. Hasil dari Economic Production Quantity (EPQ) Multi-items digunakan sebagai kendala pada model optimisasi dengan Goal Programming. Penelitian ini mengimplementasikan metode tersebut pada masalah optimisasi persediaan di salah satu Koperasi Peternak Sapi di Kabupaten Bandung Barat. Pada masalah ini, variabel keputusan pada Goal Programming terdiri dari lima produk terlaris tahun 2022. Perhitungan menggunakan metode Economic Production Quantity (EPQ) Multi-items menghasilkan jumlah produksi optimal untuk setiap produknya. Selanjutnya, dengan menggunakan Goal Programming diperoleh model untuk menentukan keuntungan optimal dengan kendala memaksimumkan produksi setiap siklusnya, meminimumkan penggunaan bahan baku, dan meminimumkan biaya persediaan sehingga diperoleh keuntungan optimal dalam satu tahun. Hasil dari implementasi menunjukkan bahwa gabungan metode Economic Production Quantity (EPQ) Multi-items dan Goal Programming berhasil diterapkan untuk menyelesaikan masalah optimisasi persediaan di salah satu Koperasi Peternak Sapi di mana seluruh target perusahaan tercapai. Kata Kunci: Optimisasi, Perencanaan Produksi, Persediaan, EPQ Multi-items, EPQ, POQ, Goal Programming. Inventory is very important for production planning. Therefore, every company must have good planning because if the inventory is carried out in too large quantities it will cause losses, and vice versa if the inventory is too small it will result in an emphasis on profits. In this study, a combination of methods between Economic Production Quantity (EPQ) Multi-items and Goal Programming will be used. Method Economic Production Quantity (EPQ) Multi-items used to determine optimal production quantities and optimal total inventory costs. Then the result of Economic Production Quantity (EPQ) Multi-items used as a constraint on the optimization model with Goal Programming. This study implements the method on inventory optimization problems in one of the Cattle Breeders Cooperatives in West Bandung Regency. In this problem, the decision variable is on Goal Programming consists of five best-selling products in 2022. The result of the method Economic Production Quantity (EPQ) Multi-items produce the optimal amount of production for each product. Next, using Goal Programming a model is obtained to determine the optimal profit with the constraints of maximizing production for each cycle, minimizing the use of raw materials, and minimizing inventory costs so that optimal profits are obtained in one year. The computational results show that Economic Production Quantity (EPQ) Multi-items and Goal Programming successfully applied to solve the inventory optimization problem in one Cattle Breeders Cooperative where all company targets are achieved. Keywords: Optimization, Production Planning, Inventory, EPQ Multi-items, EPQ, POQ, Goal Programming.
