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.

Abstract

CV. XYZ experienced production inefficiencies due to workload imbalance among production departments, particularly in the Welding Division, resulting in bottlenecks, overtime, and the inability to consistently meet production demand. This study aims to determine the standard production time, evaluate worker workload, identify the optimal workforce allocation, and compare workforce planning alternatives to improve production efficiency. A quantitative approach was employed using direct observation, interviews, and stopwatch time studies involving 20 observations for each work element. Data were validated through uniformity and adequacy tests before calculating cycle time, normal time, standard time, and workload using the Workload Analysis (WLA) method. The findings indicate that the total standard production time for one Box HEPA unit is 217 minutes. Based on WLA, the production process requires six workers distributed across four production departments. Furthermore, capacity and cost planning identified an alternative workforce configuration consisting of four workers supported by planned overtime, reducing monthly labor costs from Rp 21,658,000 to Rp 15,379,030, resulting in a cost saving of Rp 6,278,970 (approximately 29%) while maintaining the required production capacity. The proposed approach enables a more balanced workload distribution, reduces labor inefficiencies, and supports better workforce planning in a make-to- order manufacturing environment. This study contributes by integrating time study, workload analysis, and capacity-cost planning into a practical decision-support framework that can assist small and medium-sized manufacturing enterprises in optimizing workforce allocation and improving operational performance.

Abstract

This study aims to evaluate the performance of the pressing process as an effort to improve electrical energy efficiency in the Pelletizing Division of PT ISM Bogasari Flour Mills Surabaya. The research problem is based on the unachieved Key Performance Indicator (KPI) target for the electrical energy consumption ratio of 17.5 kWh/ton, where the actual consumption in 2024 reached 18.705 kWh/ton. The study employs the Objective Matrix (OMAX) method to measure productivity levels based on several performance indicators covering labor, machinery, raw materials, and electrical energy. Research data were obtained from operational production data for the period of July to December 2024. The analysis results indicate that the pressing process accounts for the largest share of energy consumption at 81.23% of total electrical energy waste in the pelletizing process. The implementation of a corrective action in the form of a reprocess raw material pathway relayout was proven effective in improving press machine work effectiveness and reducing electrical energy consumption. The average OMAX productivity increased from 5.10 to 5.34, while the average electrical energy consumption decreased from 18.80 kWh/ton to 16.12 kWh/ton. Furthermore, the company's electrical energy consumption KPI target was successfully achieved following the implementation of the improvement.

Abstract

The dumpling skin production process at UMKM Rizky Jaya currently faces significant operational challenges, specifically a production bottleneck at the manual cutting station. While noodle production has been automated, dumpling skin cutting relies on manual labor using conventional knives, requiring 7 minutes per 8.5 kg batch. This inefficiency results in physical fatigue for the 26 workers, inconsistent product dimensions, and significant lost sales during peak demand periods where orders reach up to 498 kg/day. This research focuses on the ergonomic design of a dumpling skin cutting tool based on anthropometric measurements to enhance productivity and worker comfort. Data collection involved measuring specific physical dimensions of five operators to ensure the tool’s geometric compatibility with the human body. The primary variables analyzed include shoulder height (average 143.4 cm), standing waist height (average 99.8 cm), and functional forward arm reach (average 77.0 cm). Statistical processing, including data adequacy and uniformity tests, was conducted to establish the 5th percentile as a design limit. The proposed design features a 70 cm high compact frame with a 50x70 cm cutting area, integrating a 5V laser line for visual precision and a neodymium magnet socket system for rapid blade replacement. By aligning the tool dimensions with the 5th percentile reach of 71.18 cm, the design ensures that all operators can function within a normal reach area, thereby minimizing the risk of Low Back Pain and shoulder fatigue. Implementation is projected to reduce cycle times from 7 minutes to under 4 minutes, effectively eliminating the current bottleneck.

Abstract

UD. Hardi Jaya is a shoe manufacturing enterprise implementing a job order production system, causing fluctuating production demand and workload imbalances across production sections. This study aims to analyze workload and determine optimal workforce requirements using the Work Load Analysis (WLA) method. Data were collected through observation, interviews, documentation, and stopwatch time study involving 15 production operators in the cutting, sewing, manual work, sole installation, and packing sections. Data were analyzed using data uniformity and adequacy tests before calculating cycle time, normal time, standard time, and workload values. The results indicate that several operators experienced overload conditions with workload values above 100%, including Sole Installation 1 (114.54%), Sole Installation 2 (109.52%), Cutting 1 (102.85%), and Manual Work operators. The sole installation section was identified as the main production bottleneck with an output capacity of only 68 pairs per day, which was below the production target of 102 pairs per day. Based on WLA calculations, the ideal workforce requirement was 19 workers to achieve the production target of 3,067 pairs per month, compared with the current workforce of 15 workers. However, considering production capacity and labor cost factors, maintaining the existing workforce with an overtime system was considered more economical than recruiting additional workers. The WLA method can support workforce planning, workload balancing, and improved production efficiency.

Abstract

The folding and gluing process of paperbag production at UD XYZ is still carried out manually, with workers sitting on the floor without work facilities such as tables and chairs. This condition requires workers to adjust their body posture to the work object positioned at a low level, which may cause discomfort during work. This study aims to design ergonomic work facilities in the form of a work table and chair for the folding and gluing process using an anthropometric approach. Anthropometric data were collected from 31 workers in the folding and gluing section, including knee height, buttock-popliteal length, hip breadth, sitting elbow height, sitting shoulder height, shoulder breadth, and forward arm reach. The data were processed through mean calculation, standard deviation calculation, data adequacy test, data uniformity test, and percentile calculation. The results showed that the proposed work chair dimensions consisted of a chair height of 41 cm, seat depth of 46 cm, seat width of 38 cm, backrest height of 51 cm, and backrest width of 42 cm. The proposed work table was designed with a height of 65 cm, depth of 60 cm, and length of 120 cm. The proposed workstation is expected to improve posture suitability and reduce the potential risk of musculoskeletal discomfort during repetitive folding and gluing activities. The study contributes to ergonomic workstation design for labor-intensive SMEs through task-specific anthropometric adaptation
