      Abstract
      PT XYZ menerapkan sistem produksi make to order sehingga menghadapi ketidakpastian permintaan yang memengaruhi perencanaan produksi Welding Jig, yaitu alat bantu pengelasan yang berperan dalam menjaga presisi dan konsistensi posisi komponen selama proses produksi. Sistem produksi tersebut menyebabkan perusahaan menghadapi ketidakpastian permintaan yang memengaruhi perencanaan produksi. Penelitian ini bertujuan untuk menentukan metode peramalan yang paling akurat, menghasilkan peramalan permintaan, dan memberikan rekomendasi strategi perencanaan agregat yang optimal. Metode peramalan yang digunakan meliputi moving average, double exponential smoothing, dan trend analysis yang dievaluasi menggunakan Mean Absolute Deviation (MAD), Mean Absolute Percentage Error (MAPE), dan Mean Squared Error (MSE). Hasil peramalan terbaik selanjutnya digunakan sebagai dasar dalam penyusunan perencanaan agregat melalui perbandingan dua alternatif strategi, yaitu chase strategy dan mixed strategy. Hasil penelitian menunjukkan bahwa trend analysis merupakan metode peramalan terbaik dengan nilai MAPE sebesar 5,29%. Hasil peramalan menunjukkan permintaan Welding Jig pada tahun 2026 adalah 180-187 unit per bulan. Mixed strategy menghasilkan total biaya sebesar Rp392.450.000, lebih rendah dibandingkan chase strategy sebesar Rp411.600.000. Temuan ini menunjukkan bahwa penerapan trend analysis dan mixed strategy dapat mendukung perencanaan produksi Welding Jig yang lebih akurat dan efisien pada PT XYZ.
       
      PT XYZ implements a make-to-order production system, resulting in demand uncertainty that affects the production planning of Welding Jig, a welding aid tool that functions to maintain the precision and consistency of component positioning during the production process. This study aims to determine the most accurate forecasting method, generate demand forecasts, and recommend an optimal aggregate planning strategy. The forecasting methods employed include moving average, double exponential smoothing, and trend analysis, which are evaluated using Mean Absolute Deviation (MAD), Mean Absolute Percentage Error (MAPE), and Mean Squared Error (MSE). The best forecasting results are subsequently used as the basis for aggregate planning by comparing two alternative strategies, namely chase strategy and mixed strategy. The results indicate that trend analysis is the most accurate forecasting method, with a MAPE value of 5.29%. The forecast results show that the demand for Welding Jig in 2026 ranges from 180 to 187 units per month. The mixed strategy generates a total cost of IDR 392,450,000, which is lower than the chase strategy cost of IDR 411,600,000. These findings indicate that the implementation of trend analysis and mixed strategy can support more accurate and efficient Welding Jig production planning at PT XYZ.
