Abstract

Background, The prospect of oil palm plantations is currently rising significantly to become a favourite business. However, the work activities of TBS loading-unloading workers are still performed without paying attention to ergonomic aspects and have the potential for MSDs. Aim: To map the potential MSDs of TBS loading-unloading workers, serving as a basis for improving the work system. Methods: The inclusion sample of TBS loading-unloading workers was observed and interviewed using the NBM questionnaire to diagnose potential MSDs resulting from MMH work activities. Ergo-MMH was applied to provide recommendations for improving work system design based on the AT and SHIP approaches. Results: The primary causes of MSDs are unnatural working attitudes and excessive muscle tension resulting from work systems that are not designed per the limitations of workers. Twelve body parts are directly involved in MMH activities. Conclusions, Possible MSDs on the back, left and right shoulders, right and left upper arms, right forearm, left and right wrists, left and right hands, and upper and lower neck. Implication, Ergo-MMH-based mapping of potential MSDs in manual material handling activities of TBS loading-unloading workers for the academic world; research, theory development, and education. For society, public awareness, community development, and social support. For the nation and state, work safety, economic growth, and public health. For the international community, international collaboration, standards development, and technology development

Abstract

Background. The main drive engine is an energy conversion engine that converts thermal energy resulting from chemical reactions between fuel and air into mechanical energy. The process of burning the fuel occurs due to high air pressure in the combustion chamber. Aims. This research was conducted on the MT ship. Ratu Zainab aims to determine the best practices for preventive maintenance of the cooling system on the main engine and identify the factors that impact her work on the MT ship. Queen Zainab. Methods. The method used is qualitative descriptive. The study's results highlight the importance of regular maintenance for the freshwater cooling system to ensure optimal engine performance. The main steps include preparing maintenance schedules, creating checklists, and conducting periodic inspections. Result. Common problems that often occur include a lack of suction in the cooling pump, decreased impeller performance, dirt accumulation in the seals, and leaks in the intercooler cover, thus affecting the cooling system of the main engine on the MT. Ratu Zainab's ship. Daily and monthly maintenance is recommended to detect damage early. Factors that affect the performance of the cooling system include corrosion, clogging of the cooler by dirt, and wear and tear on the standard components. Proper preventive maintenance can reduce damage, improve operational efficiency, and extend the life of machine components. Cooling system failure can lead to overheating, reduced engine efficiency, and severe component damage. Therefore, implementing preventive maintenance is a strategic step to prevent unexpected damage. Conclusion. This research highlights the importance of proactive maintenance and a thorough understanding of seawater cooling systems to ensure the optimal and safe operation of ships. Implementation. Thus, implementing proper preventive maintenance on the main engine cooling system is a crucial effort in ensuring the safety, efficiency, and reliability of the overall ship operation.

Abstract

Background. PT SMS produces bottled drinking water (amdk) in gallons and cups with Vit and Forme brands for gallon packaging and Airnes, Forma, and OK Oce brands in cup packaging. In identifying the problem at PT SMS, it was found that the work system is not well-designed and lacks ergonomics at several workstations, which has an impact on achieving less than optimal daily productivity. The output per work shift set by the company is 2,100 gallons and 3,150 boxes for cup packaging, but in fact, it can only produce approximately 2,050 gallons and 3,000 boxes. Aim. Analyze the factors that cause the work system to be less effective and less ergonomic. The formulation of work system factors encompasses physical work environment factors, equipment, infrastructure, machinery, workload factors, and organisational factors. Methods. The Macro Ergonomic Analysis and Design (MEAD) method is used to identify factors that affect the work system and then implement improvements and design changes based on the identified factors. Results. Physical work environment factors and organisational factors are problems within the work system at PT SMS, as the workspace designated for the production workflow lacks ergonomic support for employees' postures while working, and task management is inadequate. The machinery has not been crafted based on the anthropometric measurements of the workers. Oversight is absent for the work being done, and the standard time required for the production process has yet to be established. So that it increases productivity per work shift at PT. SMS is not optimal and experiences over time. Conclusions. Redesign of physical work environment facilities, scheduling of rest periods, and organisational factors through supervision from PT SMS resulted in output per shift meeting the standards set by the company.. Implication. The application of MEAD can identify factors that cause suboptimal productivity. Redesigning ergonomic physical work environment facilities, scheduling rest periods, and supervisory organisational factors within the company have an impact on optimising productivity, as measured by the output per shift set by the company
