Abstract
PT. Maha Tirta Sejahtera is a drinking water company that manages the water source into 220ml demineral water packaging. The company uses a make to stock system. In planning the production volume of PT. Maha Tirta Sejahtera has not paid attention to the production planning. This is due to uncertainty about the quantity and timing of consumer demand for drinking water products.Between January 2023 and December 2023, production is close to demand, resulting in a shortage of safety stocks.The purpose of this research is to analyze production forecasts as well as aggregate planning in order to set up production plans, so that it can meet demand in time, accurate quantity and at minimal cost. The methods used to make predictions are simple moving averages (3 and 4), weight moving average (3 and 4) and single exponential smoothing. Based on the calculations obtained chase strategy yielded the smallest aggregate planning cost worth Rs. 164,660,297. In addition to generating the smallest cost, the chase strategy method can meet total demand, meet safety stock and do not experience excess inventory.
Keywords: planning, forecasting, production costs, and drinking water

| Uncontrolled Keywords: | PT. Maha Tirta Sejahtera merupakan perusahaan air minum dalam kemasan yang mengelola sumber air menjadi air minum demineral kemasan 220 ml. Perusahaan menggunakan sistem make to stock. Dalam perencanaan jumlah produksi PT. Maha Tirta Sejahtera belum memperhatikan perencanaan produksi. Hal tersebut disebabkan oleh adanya ketidakpastian mengenai jumlah serta waktu dari permintaan dari konsumen terhadap produk air minum. Pada bulan Januari 2023 sampai bulan Desember 2023, produksi hampir mendekati permintaan sehingga mengakibatkan kekurangan safety stock. Tujuan penelitian ini dilakukan yaitu meramalkan rencana produksi serta agregat planning guna untuk mengetahui rencana produksi, sehingga pemenuhan permintaan dapat dilakukan secara tepat waktu, tepat jumlah dan meminimalkan biaya yang dikeluarkan. Metode yang digunakan untuk mendapatkan hasil peramalan yaitu simple moving average (3 dan 4), weight moving average (3 dan 4) dan single exponential smoothing. Hasil penelitian peramalan yang terbaik yaitu simple moving average 4 dengan nilai MSE 6463. Perhitungan agregat planning menggunakan metode level method dan chase strategy. Berdasarkan hasil perhitungan didapatkan chase strategy menghasilkan biaya agregat planning terkecil senilai Rp. 160.904.751. Selain menghasilkan biaya terkecil metode chase strategy dapat memenuhi permintaan total, memenuhi safety stock dan tidak mengalami kelebihan inventory. Kata Kunci: perencanaan, peramalan, biaya produksi, dan air minum |
