Abstract

PT. XYZ is a manufacturing industry in the food processing sector that focuses on the production of unsalted cassava chips. Currently, the company is unaware of the standard processing time for producing cassava chips, which impacts delivery schedules, sometimes causing delays due to the high volume of orders received. This study aims to determine the standard time required in the production process of unsalted cassava chips. The research was conducted using the Stopwatch Time Study method, as direct observations were made until sufficient data was collected using a stopwatch and observation sheets. The production process time was measured 10 times. The results showed that the time required for workers to produce unsalted cassava chips is 2181.408 seconds.

Abstract

Production defects are the main problem in making a product which can reduce production quality. Quality improvement is considered important in improving production quality. This research aims to improve quality by reducing the number of defects that occur on the production floor. This research used a quantitative method research design, and 40 data were taken randomly. Data was collected through direct observation in the field. Data analysis was carried out using the six sigma method and seven tools to determine the type of priority defects. The results of this research show that the six sigma value is still low, namely 2.67, which indicates that improving quality is needed to reduce the number of defects. Improving quality is an important factor in reducing the number of defects that occur. This research provides practical implications for company policy makers in designing strategies to improve production quality and reduce the number of defects.

Abstract

This study aims to analyze the ergonomic and economic aspects of implementing a multifunctional folding chair at CV. Fixed Interior, Semarang. The research addresses the high risk of non-ergonomic working postures and low time efficiency due to insufficient supporting facilities in the production environment. A comparison of working time before and after chair implementation was conducted, along with an economic feasibility analysis. Ergonomic assessments utilized the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA), while the economic evaluation employed Net Present Value (NPV), Internal Rate of Return (IRR), Break-Even Point (BEP), and Benefit-Cost Ratio (BCR). Results show a reduction in standard time from 678.31 minutes to 441.51 minutes, indicating a 35% efficiency increase. RULA and REBA scores reflected a lower posture risk level. Economically, the project is feasible, with an NPV of IDR 8,156,523, IRR exceeding the discount rate, BEP at five units sold, and a BCR of 14.15. Therefore, the folding chair is effective and commercially viable.
