Abstract

This research was prompted by the issues of musculoskeletal health problems and a decline in production quality among embroidery artisans at UMKM A, both of which were caused by un-ergonomic workstations. The study aimed to design a functional and ergonomic workbench by first identifying the artisans' needs and then translating them into technical product specifications. The research used the Quality Function Deployment (QFD) method, which combines qualitative and quantitative approaches. The findings revealed a negative gap between the artisans' perceptions and their expectations, with scores ranging from -3.067 to -2.467 across 30 indicators. This negative gap highlights a clear need for improvement. Based on the QFD analysis, which was processed into the House of Quality (HOQ) matrix, seven key areas for improvement were identified. These included: a height-adjustable workbench design with a total score of 45 (41.85%), empty space under the table for leg movement with a score of 18 (16.74%), a design that aligns with the artisans' preferences with a score of 18 (16.74%), flexible adjustments for the table's position with a score of 6 (5.58%), and dedicated slots or racks for storing embroidery tools with a score of 6 (5.58%). In conclusion, the QFD method proved effective in designing a workbench that meets the artisans' needs, with the ultimate goal of increasing productivity and reducing the risk of injury.

Abstract

The increasing population and intensity of food service activities have contributed to a substantial rise in cafeteria waste volume. This organic waste, characterized by its complex nutrient and moisture content, poses serious environmental challenges, particularly through greenhouse gas emissions resulting from conventional landfill practices. Within the framework of the circular economy, this study explores the potential of bioconversion of cafeteria organic waste using Black Soldier Fly (BSF) larvae as an innovative and sustainable waste management solution. A quantitative experimental method was employed to evaluate the efficiency of waste mass reduction and to analyze the added value of the resulting BSF larvae as an alternative feed ingredient. The findings demonstrate a high effectiveness of BSF larvae in reducing waste volume, as indicated by an optimal Waste Reduction Index (13.98%), an efficient bioconversion rate (96.34%), and a favorable Feed Conversion Ratio (1.04). The process proved to be rapid and cost-efficient, with an operational cost of approximately IDR 3.5 million per month, generating both economic and environmental value.

Abstract

The study is driven by the urgent need for KWT Kenanga Persada (Women Farmers Group) to transition from a conventional collective into a planned, profitable business unit. The primary objective is to optimize the vegetable nugget business strategy using the Business Model Canvas (BMC) framework and establish a viable selling price based on Cost of Goods Sold (COGS) calculations. The product innovation, incorporating nutrient-rich, flavor-neutral pakcoy is designed to counteract the low vegetable consumption rate, particularly among children. BMC analysis confirms a robust foundation for growth, supported by the unique value proposition of homemade, practical, and ready-to-serve pakcoy vegetable nuggets. Key customer segments are identified as parents with small children and health-conscious consumers. Financial feasibility was determined using the full costing COGS method. The total production cost for 15 packs was calculated at Rp 134,764, resulting in a unit COGS of Rp 8,985. Targeting a 30% profit margin, the recommended selling price is between Rp 11,500 and Rp 12,000 per pack. This strategic optimization, integrating BMC and COGS analysis, is projected to significantly enhance production capacity, expand market reach, and ensure the economic self-sufficiency of KWT Kenanga Persada.

Abstract

The aluminum High Pressure Die Casting process requires accurate real-time production monitoring to improve productivity, quality, and equipment efficiency. However, many die casting facilities still rely on manual production recording, causing reporting delays, recording errors, and limited operational visibility. This study develops an Internet of Things (IoT)-based production output monitoring system by integrating Patlite signals with a  DC350 High Pressure Die Casting machine. The system uses ESP32 microcontrollers, MQTT communication, and a web-based dashboard to automatically record machine status, shot count, production output, cycle time, downtime, and Overall Equipment Effectiveness (OEE). Experimental validation achieved 98.4% machine status detection accuracy, 99.2% production output accuracy, and 0.98-second communication latency. The system reduced manual recording time by 87%, improved production transparency and data reliability, and supported Industry 4.0 implementation in aluminum die casting manufacturing.

Abstract

PT X in Lampung uses a Shiploader as the primary equipment for coal loading operations; however, the high level of downtime has resulted in suboptimal operational effectiveness. This study aims to identify the factors contributing to the low effectiveness of the machine and propose improvement recommendations. The methods employed include Overall Equipment Effectiveness (OEE), Six Big Losses, Fishbone Diagram, and the 5W+1H approach. The results indicate that the average OEE value was 76%, which is below the World Class OEE standard of 85%, with an Availability of 90%, a Performance Rate of 85%, and a Quality Rate of 99%. The Six Big Losses analysis revealed that Reduced Speed Losses accounted for the highest loss at 15.62%, while Equipment Failure Losses were the primary cause of downtime, with a total breakdown time of 4,141 minutes or 13.6%. Improvement recommendations include implementing scheduled preventive maintenance, conducting routine inspections of the oil cooler system, using spare parts that comply with manufacturer specifications, enhancing operator competence through regular training, ensuring compliance with Standard Operating Procedures (SOP), and performing periodic evaluations to improve Shiploader reliability and increase the OEE value.

Abstract

The batupack handling process still experiences waste that results in prolonged processing time, excessive fuel consumption, and increased operational downtime. This study aims to identify the sources of waste, analyze their root causes, and evaluate process efficiency using the Lean Manufacturing approach through Value Stream Mapping, Process Activity Mapping, VALSAT, and Fishbone Diagram. The findings indicate that the dominant types of waste are transportation, waiting, and motion. The proposed improvements successfully reduced the cycle time from 313 minutes to 130 minutes and the lead time from 468 minutes to 153 minutes, increased Value Added activities from 20% to 78.4%, and reduced Non-Value Added activities from 41% to 2%. In addition, the improvements decreased operational downtime from 23.17 hours to 1.83 hours per month, reduced diesel fuel consumption from 4,716.61 liters to 1,061.23 liters per year, increased production potential by 85,360 tons annually with an additional profit of IDR 94.49 billion, and lowered CO₂, SOx, and NO₂ emissions. These findings demonstrate that the proposed approach effectively improves operational efficiency while supporting the sustainability of the material handling process.
