Abstract

Raw material inventory control is used to place orders and ensure that shrimp raw materials arrive in a timely manner in accordance with consumer demand. This will expedite the course of the production process. This research was conducted at PT. Grahamakmur Ciptapratama Sidoarjo with the aim of knowing and analyzing the control of raw red ginger in frozen shrimp products. The method used is the Economic Order Quantity (EOQ) Method with the Lot For Lot (LFL) Technique. In addition, safety stock analysis, Maximum Inventory, warehouse capacity and Reorder Point analysis were carried out. The results of the study showed that inventory costs using the EOQ technique were lower than the company method or using the LFL technique. The EOQ technique produces an inventory cost of IDR 292,591.00 in 2017 with an order frequency of 105 times and in 2018 of IDR 289,750.00 with a booking frequency of 116 times. In the LFL technique inventory costs are more expensive, but the planning technique in the LFL method can be applied by companies in anticipation of raw material inventory if there is a small inventory. If the company applies the EOQ method, the company purchases raw materials in a larger amount, but the warehouse capacity in the company can still be met, this can be seen from the calculation of Maximum Inventory and warehouse capacity.

Abstract

The research aims to determine the standard working time on the cutting and packaging of glutinous jenang "JELITA". The cutting and packaging part is the part of the production process that determines the amount of production produced. The determination of standard time is done through the analysis of working methods and working time in those parts. The method used is the calculation of the standard time in the determination of operating process chart, left right handed chart, and flow diagrams. The results showed that improvements in working methods based on work maps were obtained based on proposed improvements. The proposed improvement results in the effectiveness and efficiency of the operating process time up to the layout on the work system, while in the determination of the default time produces 52 seconds of the standard time of the cutting process and 226 seconds of the raw time of the packaging process.
