Production Planning On Lettuce Commodity Green Curl (Lactuca sativa L)

Abstract

PT Sayuran Pagi is the first hydroponic company in Depok City. The obstacle faced by PT Sayuran Pagi is that there is still often a shortage of curly lettuce products, so it cannot meet consumer demand. This is because the company has limited production capacity and limited supply of curly lettuce production from partner farmers. Pest and climate factors also affect the availability of curly lettuce vegetable supply from partner farmers. Production planning needs to be done by minimizing costs through forecasting demand for future periods as well as efficient scheduling. The forecasting methods used in this study are double exponential smooting, ARIMA, trend analysis, aggregate planning and Master Production Schedule (MPS). This study obtained the results of forecasting with the smallest error value, namely the trend analysis method of the quadratic trend model with a value of 14451.0. For aggregate planning, the method that produces the least cost is the chase strategy. Forecasting using the chase strategy method is the basis for the next 1 year production master schedule. The results of the production master schedule show the amount of production that must be available in different quantities every month.
