Abstract

In making mine roads, workers carry out work in conditions that are less comfortable carrying out work activities for long periods of time. For example, surveyors carry out their activities from morning to evening in hot or rainy weather conditions and require little time. Supervise the control of work so that it complies with the directions and time that has been determined. In carrying out these activities, high energy and precision is required, resulting in mental and physical workload. By carrying out this research, an evaluation of mental workload will be carried out to find out how much mental workload is felt by workers in carrying out work activities and what load factors most influence workers' mental workload. The analysis was carried out using the NASA-TLX method to identify the mental workload experienced by workers. The results of data processing show that the section that has the highest workload is the supervisory section with an average of 81.1, then the operator section with an average value of 80.9, and the lowest is the survey section with an average value of 80. In the shift comparison The workload for operators on the morning shift has a total score of 822, while on the night shift the total score is 796. Then on the morning shift the supervisor has a higher workload with a total score of 335, while on the night shift the total score is 314. So it can be seen that the workload during the shift morning shift is greater than the night shift.

Abstract

Data reveals that at UMKM Tahu Prapto, out of 9,450 tofu products produced, 1,016 products were defective, indicating quality control issues in August 2024. By implementing the six sigma method, it is expected to identify defects to determine the company's sigma value, so that the company can improve its sigma value to compete in the market and provide improvement recommendations aimed at reducing the existing product defects in Tahu. In its implementation, six sigma has 5 (five) steps to improve business performance, namely define, measure, analyze, improve, and control, so that problems or opportunities, processes, and customer requirements must be verified and updated at each step. Further analysis using the Pareto diagram identifies specific defects in the tofu product, such as dirty tofu, incorrect size, unpleasant texture, and bad odor. The proposed improvements include scheduling regular equipment cleaning, ensuring the maintenance and cleanliness of production machines, and maintaining a clean working environment to prevent contamination of tofu products

Abstract

Quality control is a crucial aspect in the leather tanning industry to maintain competitiveness and minimize defective products. UD Rochmah Hidayat faces a problem with defect rates in vegetable-tanned cattle leather production reaching 20% of total production, exceeding the company's quality control limit of 10%. This study aims to identify factors causing defects and formulate improvement proposals to enhance product quality using the Plan, Do, Check, Act (PDCA) method and 5W+1H. Research data was obtained from the production period January to December 2024 with a total of 5,760 leather sheets produced and 1,152 sheets experiencing defects. Analytical tools used include check sheets, Pareto Diagrams, Fishbone Diagrams, control charts, and histograms. Identification results show three dominant types of defects: stiff defects (472 sheets), hole defects (384 sheets), and spot defects (296 sheets). Fishbone Diagram analysis identified main causal factors including human aspects (lack of supervision and accuracy), materials (differences in leather quality from various suppliers and damage due to disease), and methods (errors in the skinning process, imbalance in chemical composition, and improper storage conditions). Control chart analysis shows unstable production processes with several data points outside UCL and LCL limits. Improvement proposals using the 5W+1H method recommend adding supervisors, purchasing raw materials from one trusted supplier, training in knife usage according to standards, standardizing drying time, and using humidity and temperature measuring instruments in warehouses. Implementation of recommendations is expected to reduce defect rates to established control limits.

Abstract

The amount of waste in urban areas, especially in Yogyakarta City, is growing, which shows the need for better and cleaner waste management. Traditional trash bins need people to touch them directly, which can make them less clean and uncomfortable to use. This study focuses on creating an automatic trash bin that opens and closes without touching, using an ultrasonic sensor. This system is being developed for the Yogyakarta City Environmental Agency (DLH). The system uses an ultrasonic sensor to sense when something is near, a microcontroller to control everything, and a servo motor to open and close the bin automatically. The research process includes reading previous studies, designing the system, building a prototype, and testing how well it works. The test results show that the system can accurately detect objects within a certain distance and operate the opening and closing function smoothly and quickly. Using this automatic trash bin can help make public spaces cleaner, more comfortable for users, and support the development of technology-based waste management solutions in Yogyakarta City.

Abstract

This study aims to redesign the production facility layout at PT. MMP in order to improve material flow efficiency and reduce material handling costs. The methods applied in this research are Activity Relationship Chart (ARC), From-To Chart (FTC), and Blocplan. Data were collected through direct observation, interviews, and documentation related to production processes, inter-department distances, and material movement frequencies. The results indicate that the existing layout is inefficient due to long material transfer distances. By redesigning the layout using the Blocplan method, a more optimal facility arrangement was obtained with reduced travel distances and improved production flow. The material handling cost analysis shows a decrease from Rp177,000 in the ARC layout to Rp64,000 in the Blocplan layout. Therefore, the Blocplan method is proven to be more effective in improving facility layout efficiency and reducing operational costs.
