Abstract

Fake eyelashes are made in Indonesia by a variety of industries. There are issues within the company that have an impact on the output. Waste issues in the manufacture of fake eyelashes are the cause of inconsistent production output, such as flaws in the goods, waiting times, and improper processing. A lean manufacturing approach is required to find a solution to the issues that PT. X is experiencing as a result of the data model. The Value Stream Mapping (VSM) method, the Activity Based Costing (ABC) method integration, the Value Stream Analysis Tools (VALSAT) method calculation, the Root Cause Analysis (RCA) method, and then gives recommendations for improvement. The use of continuous flow, task combinations, and the delivery of raw materials once each week are all suggested improvements. When current cost integrated value stream mapping is compared to future cost integrated value stream mapping, the production lead time drops from 0.5 days to 0.36 days, the total value-added cost drops from 2.049 to 1.561, the total non-value-added cost drops from 12.754 to 11.243, and the travel distance drops from 99 meters to 79 meters.

Abstract

Pertamina gas stations have an important role in the national economy. Optimizing performance in this sector is very necessary to improve Pertamina's internal performance, optimize state revenue, and increase customer satisfaction. At the motorcycle Pertalite filling work station, long queues often occur. This study aims to evaluate the current fuel filling work method, so that optimization analysis and improvement proposals can be carried out. The methods used are time study and MOST. The results of the time study from observations of 300 respondents from 15 gas stations in Yogyakarta are that the average working time of respondents is 33.78 seconds with a normal time of 33.19 seconds and a standard time of 44.85 seconds. While the results of processing using MOST obtained a TMU value of 810 if converted into seconds to 29.16 seconds. Furthermore, an analysis and improvement proposal were carried out which gave a working time result of 19 seconds, with a normal time of 18.62 seconds and a standard time of 25.19 seconds. Things that need to be improved in the process of filling Pertalite fuel for motorbikes are to prepare the motorbike with the seat and tank already open in 1 queue before the work station, make payments during the filling process, and move the motorbike immediately after the filling process is complete (closing the tank and seat is done outside the work station).

Abstract

Mr. Wash laundry is one of the Small and Medium Enterprises (SME) located in Yogyakarta. This business was founded in 2015 with 2 workers. In work operations, many involve physical activities that can cause fatigue and musculoskeletal complaints, causing decreased productivity and miscommunication to consumers. Therefore, this research was conducted to improve the work system to minimize these impacts. The method in this study uses an ergonomics participator. This method involves a participatory team, namely ergonomists, owners, and workers. The result of this research is the design of an ironing table and chair using the anthropometric specifications of workers which can reduce fatigue and musculoskeletal complaints.
