Abstract

Workload is something that arises due to excessive activity demands. The workload is not proportional to the number of available workers because of the high target of pipe production while the number of workers is lacking so that human resources cannot work productively, especially in the production department at PT. Harapan Jaya Multi Bisnis. The purpose of this study is to determine the workload of employees in pipe production and determine the optimal number of workers. This study uses the Work Load Analysis (WLA) method to analyze the workload in determining the optimal number of workers. The results of this study after calculating the workload, it is proposed that the fixed cutting section is 2 people with a workload of 62.65%. In Branding, in real terms there is 1 person with a total workload of 11.73% and an average workload of 11.73%. After calculating the workload, it is proposed that the shooting section still be 1 person with a workload of 11.73%, because if additional workers are added, the workload will be too low. The time needed to complete the activity is 7 hours per day. After calculating the workload, Quality Control is proposed to be 1 person, because if additional workers are added, the workload will be too low, namely 7 hours per day.

Abstract

This study aims to analyze the implementation of Material Requirement Planning (MRP) method in controlling raw material inventory for aluminum wardrobe production in Amal Jaya SME. The inability to accurately predict the average number of customer orders each month indicates unfulfilled consumer demand. Therefore, effective raw material control becomes crucial to ensure availability in accordance with demand. The objectives of this research are to evaluate the management of raw materials using the MRP method and identify its impact on cost efficiency of raw materials in the production process. Additionally, this study aims to optimize raw material inventory to maximize customer demand fulfillment. The MRP method was chosen as the primary approach in this research. The results of the analysis indicate that the implementation of MRP method with Lot for Lot (LFL) lot sizing is the most efficient choice in controlling raw material inventory. Based on calculations using lot-for-lot and Economic Order Quantity (EOQ) methods, the most efficient inventory expenditure incurred by the company amounts to Rp. 26,274,840. Thus, ordering raw materials with Lot for Lot lot sizing can be used as a solution to optimize the control of aluminum wardrobe inventory in Amal Jaya SME.

Abstract

PT. Kurnia Luwuk Sejati or PMKS Toili is one of the palm oil industries that processes fresh fruit bunches into Crude Palm Oil and Palm Kernel Oil. Due to high market demand, palm oil plantation workers are required to complete their tasks on time with a target of 8 working hours per day. Several workers have complained about the physically and mentally burdensome nature of their work, leading to harvest results that sometimes do not meet the desired quality standards. This research aims to determine the level of mental workload experienced by the workers using the SWAT and Work Sampling methods processed using the DosBox 0.74 application. The measurement results can indicate the extent of mental workload perceived by the employees, with three significant factors influencing the employees' mental workload: the time dimension accountsfor 67.16%, the effort dimension accountsfor 13.87%, and the stress dimension accounts for 18.97%. Recommendations for improvement need to be implemented to minimize and reduce the employees' workload, including improving working conditions and the work environment, increasing rest time, effectively distributing tasks, and increasing the number of operators or employees to achieve production targets.Keywords – Mental Workload, SWAT, Work Sampling
