Abstract

Yogyakarta is known as a city of students, many public and private universities. Based on this, students come from several regions to study. The learning process in higher education cannot be separated from facilities that support learning activities such as study tables and laptops. Students use laptops every day for a long time. Most students complain that the study table is not comfortable when used but it also causes students to tire more quickly. Fatigue is felt in the neck, back, legs and hands. Therefore, it is necessary to redesign the student desk to make it more ergonomic. The method used in redesigning student desks is value engineering. Function identification is performed using FAST diagrams. From the results of the identification of needs and functions, it is necessary to repair and redesign student desks. So from this study, the results of the student study table design with the addition of parts to be able to adjust the height and slope of the laptop, a place for glasses and cables, an adjustable study table height and also a footrest. Then the size of each table is adjusted to the dimensions of the Indonesian anthropometric body, the final result of this research is a more ergonomic student desk design.

Abstract

The painting operator activity is done manually. This painting activity is carried out in a specific position and is carried out continuously, causing musculoskeletal disorders. This study aims to determine the working posture of the painting operator using the OWAS, RULA, and REBA methods. Data collection was carried out by distributing Nordic Body Map questionnaires to operators with several complaints. OWAS and RULA methods were used to find and analyze operator behavior that could cause musculoskeletal disorders and injuries. The results of the OWAS calculation show that the risk level score is 2. At the same time, the RULA risk level score is 3. The analysis results show that several operator postures pose a musculoskeletal risk, so improvements must be made. Hopefully, this proposed improvement will help reduce the risk of musculoskeletal injuries

Abstract

PT. Exedy Manufacturing Indonesia is an automotive industry company that produces Clutch Assy Wheel 4 – Wheel 2 Clutch / Clutch, E. Spring, RLS Plate Motorcycle. Their average production capacity is 1,103 units of clutch discs per day. The company has a product defect standard that cannot exceed 3%, but currently, the average rate of product defects reaches 10%. There are three highest numbers of defective products, consisting of 609 units of consumable blades, 533 units of small size, and 571 units of uneven surface. This means that the quality control carried out by the company is still not optimal and needs improvement. This study aims to determine the number and the causes of defects and quality improvement using statistical quality control (SQC) and fault tree analysis (FTA) methods. From the SQC, it shows that 4 data exceed the upper control limit thus improvements need to be made. The results of the FTA method showed there are 10 basic events in determining the cut set, namely poor material quality, lack of experience, poor work procedures, fatigue, lack of skill, haste, air temperature, poor lighting, untidy area, and shrinking machine performance. Then a proposal for improvement is made to improve the factors that influence the cause of the defect

Abstract

The process of taking natural dyes from strobilanthes cusia leaves in a very simple way is carried out at UMK Shiungu Temanggung. The process was carried out by soaking the leaves and twigs of the cusia strobilantes in water, with a time of 3 days, and a solvent-to-material ratio of 6:1. The raw materials in the form of intact leaves and twigs cause the maceration results to be less than optimal and cause waste in the form of leaves and twigs which are increasingly stinking. Starting from this problem, it is necessary to carry out research to be able to determine the best conditions for the dye collection process. The maceration process, which was carried out using intact leaves and twigs of Cusia strobilantes that were not chopped, with a maceration time of three days and a solvent-to-material ratio of 6:1, resulted in a solution with a very small absorbance value. For red color with a wavelength of 678 nm the solution has an absorbance value of 2.375. Whereas for the purple color with a wavelength of 409 nm the solution has an absorbance value of 5.275. In addition, the waste obtained is difficult to process because it is large and interlocking and smells bad so it disturbs the environment. Research on the process of maceration of Cusia strobilantes leaves with variations in leaf size, a ratio of solvent to material, and maceration time, shows that the smaller the size of the material and the greater the time used, the greater the absorbance value of the macerated solution, while the ratio of solvent to material indicates an optimal point. The best conditions chosen are process conditions that produce maximum maceration results and facilitate the waste treatment process
