Abstract
PT Petrokimia Gresik is a company engaged in the production of fertilizers. The existence of monthly targets that must be met in the production of ZK fertilizers, the Company must increase production so that the Company experiences a high level of raw material losses which can result in inefficiency in production costs that must be incurred. Therefore, the problems that occur in the Company must be resolved by reducing ZK fertilizer production losses so that the method that will be used in this study is the time series forecasting method by analyzing historical data of ZK Units in 2024. This study uses Microsoft Excel software to facilitate data calculation. From the results of data processing, it was found that this method plays a role in increasing the efficiency of raw material use in the coming period so that significant losses do not occur. Based on the results of the calculations in this study, several forecasting error analyses were obtained from several methods used. By using the Single Exponential Smoothing method, the MAD result was 147.82 which was the most effective compared to the other 2 methods. So the Company can find out future production forecasts without losses in raw materials.
