Time Study Analysis on Rice Milling Process at Rice Milling Unit (RMU) “Teaching Industry” Unsoed

Abstract

Rice is a major food crop in Indonesia that requires special attention in the milling process to ensure efficiency of working time. This study aims to identify the division of work elements in the rice milling process, determine the standard time used by operators, and provide recommendations for improving the work system in the Unsoed “Teaching Industry”. Research data were collected by measuring the time of each work element in the rice milling process using a stopwatch. The work elements are divided into two groups: rice milling elements and rice packaging elements. The analysis methods used include data adequacy and uniformity tests as well as calculations of standard time and normal time. The results of the analysis show that the standard time for the rice milling process is 5,920.55 seconds per 100 kg of rice, while the standard time for the rice packaging process reaches 27,549.81 seconds per 100 kg of rice. The time required is still relatively long compared to previous studies, so several improvements are recommended, including eliminating unnecessary work elements, carrying out thorough maintenance of the tools in the RMU, and placing a bucket in the outlet hole when changing sacks to reduce the time to collect scattered rice. In addition, in the rice packaging process, the element of rice sorting can be eliminated. Other recommendations include improving the working environment by encouraging workers to wear masks during the rice milling process.
