Abstract

UD. TGM is one of SMEs located in Blora, Central of Java. They can produce 60 – 150 pallets of paving block per hour. Based on observations and measurements, the noise level around production machines is above 90 dB and the temperature around UD. TGM reaches 34°C. Those conditions do not match with the regulatory standards by Ministry of Health of Republic Indonesia. In addition, based on NBM questionnaire, there were 10 complaints of very sick, 7 complaints of pain, and 7 complaints of moderate pain. The worker's cardiovascular load was 36.4% (or needed improvement). Based on the REBA assessment informed that a corrective action needs to be taken immediately. This study aims to analyze the work system totally and provide improvement recommendations. We proposed recommendations by total ergonomics approach collaborated with fishbone diagrams, tree diagrams, and PDPC diagrams. The recommendations were UD. TGM need to create a supervisory team, create work instructions, design additional of transportation tools like a hand stacker, replace dirt floors with paving, enlarge air ventilation holes and add roof height. Then, the evaluation of the recommendations by Catia software, the REBA score was reduced from level 3 to level 1 (or low risk).

Abstract

Optimizing work movements is crucial for enhancing efficiency and reducing injury risks in industrial environments. Methods like Methods-Time Measurement (MTM), Work Factor (WF), and Maynard Operation Sequence Technique (MOST) are commonly used to analyze and optimize the workstations. However, there remains a lack of accessible tools for rapid and accurate time measurement. This study aims to develop a web-based and Android application designed to assist both students and professionals in calculating work times and optimizing movements (such as: material handling) more efficiently. The application was evaluated using the WebQual method, focusing on usability quality, information quality, and interaction quality. Evaluation results yielded scores of 82.3% for usability, 85.7% for information quality, and 80.5% for interaction quality. Validity and reliability tests demonstrated a Cronbach's Alpha coefficient of 87%, indicating very high reliability. The integration of MTM within this application has proven effective in accelerating work time calculations compared to manual methods and in improving movement efficiency, which directly contributes to reducing injury risks.
