Data pengiriman karet SIR (Standard Indonesian Rubber) dari 2020-2022 digunakan untuk memproyeksikan produksi selama 12 bulan ke depan. Metode yang digunakan meliputi Double Moving Average, Double Exponential Smoothing, dan Holt Winter Multiplikatif. Metode terbaik ditentukan berdasarkan nilai error terkecil menggunakan Mean Absolute Percentage Error (MAPE). Validasi dilakukan dengan metode moving range dan uji F untuk memastikan keakuratan hasil peramalan. Hasil penelitian menunjukkan metode Holt Winter Multiplikatif memiliki error terkecil dan validasi memuaskan, sehingga direkomendasikan untuk PT Indo Java Rubber Planting Co. Implementasi metode ini diharapkan dapat membantu perusahaan mengelola kapasitas penyimpanan, mengurangi risiko overkapasitas, dan menjaga kualitas produk.

This research aims to design production forecasting with time series method to overcome this problem. SIR (Standard Indonesian Rubber) rubber shipment data from 20202022 is used to project production for the next 12 months. The methods used include Double Moving Average, Double Exponential Smoothing, and Holt Winter Multiplicative. The best method is determined based on the smallest error value using Mean Absolute Percentage Error (MAPE). Validation is done with the moving range method and F test to ensure the accuracy of the forecasting results. The results showed that the Holt Winter Multiplicative method has the smallest error and satisfactory validation, so it is recommended for PT Indo Java Rubber Planting Co. The implementation of this method is expected to help companies manage storage capacity, reduce the risk of overcapacity, and maintain product quality. With Holt Winter Multiplicative, the company can plan production more effectively and efficiently, adjust production to market demand, optimize warehouse usage, and reduce storage costs and increase customer satisfaction.
