Abstract

CV ABC is one of the manufacturing industries in Central Java that produces furniture products. The resulting products have good quality so that 60-70 percent of their products are exported while the rest are marketed domestically. The current production process, the application of occupational safety and health have not been fully implemented. From company data for three years, the number of work accidents is 9, 8, and 10 times. The number of hours lost was 154 hours, 168 hours, and 224 hours. Efforts are needed to prevent work accidents that can reduce work productivity. Based on the existing problems, the company needs to identify the causes of work accidents with a fault tree analysis method approach. The factors that cause work accidents can be identified, namely the work area, production process and storage and transfer. This work accident will cause worker productivity to decrease. In 2016 the productivity value was 0.99925, in 2017 the productivity level was 0.99929. In 2017 there was an increase in productivity due to the reduced number of lost hours. In 2018 there was a decrease in the productivity level to 0.99910 due to the increase in the number of lost hours of employees becoming more. The results of the "t" test measurement showed a decrease in the frequency level in 2017 and an increase in the frequency level in 2018. Severity measurements decreased in 2017 and increased in 2018. The safe t value in 2017 has increased. In 2018 there was a decline, so productivity in 2018 decreased. From the relationship between work safety and productivity, it is clear that work accidents cause productivity to decline. In 2016 the productivity value was 0.99925, in 2017 the productivity level was 0.99929.

Abstract

Astra Daihatsu Motor Engine Plant is a manufacturing company that produces motor vehicle engines. In the production process, Logistic supply partner Machining is a Logistics Sub-division whose task is to carry out the distribution process of small parts. Supply is carried out by Man power to the available shelves on the production line, in the process this activity has some potential for waste or what is called Muda. If supply activities experience problems that cause delays in the supply process, then the worst possibility is that the production line can stop and make the company suffer losses. For this reason, it is necessary to make efforts to eliminate these Muda potentials which is the purpose of this research. Process small part is carried out using dolly. This can lead to the potential for Muda. Of the 8 types of Muda, there are potential for 3 types, namely muda waiting, muda transportation and muda motion. For this reason, it is necessary to increase the number of dolly, in order to avoid the potential of double handling. In addition to this dolly, the manufacturing process must follow the rules of anthropometry, which is a collection of numerical data related to the characteristics of the human body in the form of size, shape and strength, as well as the application of these data to handling design problems. In addition to anthropometric data, data are also needed that will affect the design of the dolly such as the size and shape of the box to be carried. By using the 50% percentile of anthropometric data and also box size data, the dolly design to be made is 156 cm long, dolly width 83 cm, dolly height 83 cm and dolly handle height is 96 cm.
