Abstract

This article reports on technological mastery assistance in three small metal forming industries in Indonesia. Problems in the blangking and piercing separately process caused increased production time which resulted in inefficiency cost. Therefore, the expert team aided in metal forming technology through participatory action research (PAR) methods and experimental methods through reverse engineering for several products. The PAR method involves optimal contribution and participation from the industry. Assistance in mastering technology in small metal-forming industries reduces the manufacturing process from seven to three stages, increasing efficiency. The press machine's tonnage capacity must balance with the force blanking/piercing requirement. The minimum press machine requirement is 6.7 tons, and based on the availability of existing press machines, the expert team recommends a 20-ton capacity press machine. Total efficiency can be further increased by implementing full progressive die technology by combining piercing, blanking, and bending processes.

Abstract

Human resources are the most important assets for a company. Each worker has their own role and obligations which will result in their own workload. PT. ABC is one of the companies that provides surface finishing services, electroplating services and electrode position painting. From the observation results, there are complaints about insufficient time adjustments to meet targets and demands from superiors for these targets, resulting in increased mental workload. In order to overcome this problem, it is necessary to measure the mental workload felt by employees using the NASA-TLX method, this method measures 6 dimensions of workload including Mental Demand, Physical Demand, Temporal Demand, Performance, Effort and Frustration Level. This study shows the acquisition of workload scores, it is known that 75% of employees have a high category workload and 25% of employees have a very high category workload. The dominant aspects that cause the amount of mental workload of PT.ABC employees are Mental Demand of 19.62%, Effort of 19.40% and Physical Demand of 17.93%. In order to minimize the level of mental workload, namely by adding some workers in the production and quality control sectors.
