Abstract

This research discusses a company engaged in printing newspapers or newspapers. There are 3 main ingredients in making newspapers, namely stencil paper, plate cleaning liquid and plate. The problem faced by the company is that the supply of the main ingredients has weaknesses, including delays in fulfilling the demand for the main ingredients with the uncertainty of the company's demand with the supplier of the main ingredients for making newspapers. The purpose of this research is to determine the number of main raw material stocks in newspaper production using the probabilistic economic order quantity (EOQ) method so as to minimize the total inventory cost. Mapping of the main material requirements using forecasting, calculation of economic order quantity (EOQ) probabilistic and calculation of inventory costs and the difference in savings in total inventory costs. The results of the probabilistic economic order quantity (EOQ) are 1 roll of stencil paper, 1 jug of plate cleaning liquid and 16 boxes of plates with a difference in cost savings of Rp. 108,867,156.

Abstract

The primary focus of this research revolves around the measurement of productivity and the factors that impact Crude Palm Oil (CPO) production which currently faces challenges in assessing whether existing productivity falls into the 'satisfactory' category. The contribution of this study is conducting a comprehensive productivity assessment, focusing on metrics and identifying the causes of productivity decline, especially potential points of failure. The measurement indicators use the Objective Matrix (OMAX) method which includes five ratios, including raw material utilization, energy consumption, labor efficiency, optimization of production targets, and production capacity utilization. The Analytical Hierarchy Process (AHP) is used to assign relative weight to factors that contribute to overall productivity. In addition, Failure Modes and Effects Analysis (FMEA) functions as a tool to determine the causes of decreased productivity by considering the potential for failure to occur. The research results show that productivity reached its highest point in March at 219.93% and the lowest in July at -67.33%. Based on the score assessment, this decline was mainly caused by the lack of optimal achievement of production targets, symbolized by a ratio of 4 to a score of 45. Potential causes for this ratio include non-compliance in selecting FFB that meets standards, and production standards that are too ambitious. targets, and mental and physical fatigue and stress. To improve overall performance, proposed improvements include the application of Internet of Things (IoT) technology, such as the use of sensors and automation systems in production processes, as well as investment in agricultural technology as a monitoring system. This increase is aimed at achieving higher production targets and overall efficiency.
