Optimasi Agregat Planning Untuk Meningkatkan Efisiensi Produksi Botol SAS 300 Ml Berbasis Seasonal Demand di PT XYZ

Abstract

Penelitian ini bertujuan mengoptimalkan perencanaan agregat untuk meningkatkan efisiensi produksi botol SAS 300 ml di PT XYZ, yang menghadapi tantangan fluktuasi permintaan musiman. Metode yang digunakan meliputi analisis permintaan historis, peramalan dengan Multiplicative Decomposition, serta evaluasi beberapa strategi perencanaan agregat. Dari hasil analisis yang dilakukan, dapat diketahui bahwa metode Multiplicative Decomposition memiliki akurasi peramalan paling tinggi dibandingkan metode lainnya, sehingga dijadikan dasar penyusunan strategi produksi. Mixed Strategy 2 dipilih sebagai strategi paling efisien dengan biaya terendah dan stabilitas tenaga kerja yang baik. Master Production Schedule (MPS) disusun mingguan dengan memperhatikan permintaan, stok awal, safety stock, dan lead time. Master Requirements Planning (MRP) dilakukan secara terintegrasi untuk memastikan ketersediaan bahan baku dan kelancaran produksi. Implementasi model perencanaan agregat yang responsif terhadap permintaan musiman terbukti mampu meningkatkan efisiensi produksi dan membantu perusahaan memenuhi kebutuhan pasar secara optimal.

This study aims to optimize aggregate planning to increase production efficiency of 300 ml SAS bottles at PT XYZ, which faces the challenge of seasonal demand fluctuations. The methods used include historical demand analysis, forecasting with Multiplicative Decomposition, and evaluation of several aggregate planning strategies. From the results of the analysis, it can be seen that the Multiplicative Decomposition method has the highest forecasting accuracy compared to other methods, so it is used as the basis for compiling a production strategy. Mixed Strategy 2 was chosen as the most efficient strategy with the lowest cost and good workforce stability. The Master Production Schedule (MPS) is prepared weekly by considering demand, initial stock, safety stock, and lead time. Master Requirements Planning (MRP) is carried out in an integrated manner to ensure the availability of raw materials and smooth production. The implementation of an aggregate planning model that is responsive to seasonal demand has been proven to increase production efficiency and help companies meet market needs optimally.
