Abstract

The efficiency of the silica sand refining process significantly affects the quality of metal casting at CV Karya Gemilang Teknik, Sidoarjo. Currently, the company performs sand refinement manually, which leads to excessive processing time, inconsistent results, and operator fatigue. This study aims to design an ergonomic sand-refining machine using an anthropometric approach to improve both operator comfort and production productivity. A combination of field observation, anthropometric data collection, ergonomic design analysis, and prototype testing was employed. The key anthropometric parameters considered were standing shoulder height and arm reach, analyzed using statistical measures such as mean, standard deviation, and percentile. Based on these results, the optimal machine dimensions were determined at a height of 92.27 cm and a width of 67.5 cm to accommodate the majority of workers. The designed machine applies a hammer mill mechanism with a 1 HP electric motor, steel frame, and V-belt transmission system. Experimental results indicate that the new design significantly reduces sand-refining time, enhances operator posture and comfort, and produces finer and more uniform sand particles. Consequently, the proposed ergonomic design contributes to improved efficiency, consistent product quality, and higher productivity in the casting process at CV Karya Gemilang Teknik

Abstract

The charcoal briquette MSME in Gedangan Subdistrict, Sidoarjo Regency, is a business engaged in the production of alternative energy based on coconut shell waste and sawdust. The production process involves burning, grinding, mixing adhesives, molding, and drying. However, based on observations, around 30% of raw materials are not optimally utilized because they become waste in the form of ash and coarse charcoal. This condition causes low production efficiency and increased operational costs. In addition, the capacity of the existing charcoal briquette drying machine is still limited, the molding results are often inconsistent, and the durability of the machine material is relatively low. This study aims to design a more efficient charcoal briquette molding machine that suits the needs of MSMEs by using the Quality Function Deployment (QFD) approach. This method focuses on translating user needs into technical product requirements, so that the machine design not only considers technical aspects but also meets user expectations. The design results are expected to increase productivity, reduce raw material waste, produce briquettes with uniform quality, and reduce production costs. With a QFD-based charcoal briquette molding machine design, Arang Briket SMEs are expected to maintain production continuity, increase competitiveness, and become an example of the application of appropriate technology in biomass-based alternative energy processing.

Abstract

PT XYZ is a company engaged in the manufacture of semi-finished wood products. Based on field observations, where products come in varying sizes and shapes, it is important to consider ergonomic aspects in layout design. Inefficiencies in the current warehouse layout were found, resulting in long material handling times and operational disruptions. The purpose of this study was to improve the layout of the finished goods warehouse area and facilities by redesigning the facility layout at PT XYZ to optimize the finished goods warehouse layout. This study used the Activity Relationship Chart (ARC) method and volume handling analysis. A redesign was proposed to improve space management and material flow. Data were collected through observation, interviews, data analysis, and discussion. The proposed layout minimizes material movement distance and improves accessibility and ergonomics. As a result, the original facility produced 26,480 units, while the proposed facility produced 15,772 units. There was a decrease in handling volume of 10,708 units, or 40.43%, after the layout change.
