In the current era of globalization, information technology is developing rapidly. As for technology, which is equipment created to make human work easier, when achieving good progress in the work process of PT Plaza Auto Prima, it is absolutely necessary to have a technique that supports and provides satisfactory service for customers. Based on this, the author tries to analyze a method used when employees work in the Plaza Auto Prima environment regarding the work ergonomics they currently apply at PT Plaza Auto Prima, which to date has not seen any improvement. The method used is direct observation and assessment of work posture using the REBA method. The research subjects were mechanics who worked in the installation or removal of car wheels. The data obtained is analyzed to determine the REBA score and the level of risk faced by workers. The research results show that the mechanical work posture at PT Plaza Auto Prima (Toyota) Tendean has significant problems. Analysis using the REBA method produces a final score of 8, which indicates a high risk level and requires immediate improvement. Factors that contribute to this high risk include the lack of ideal work ergonomics and limited supporting equipment. This increases the risk of injury and illness to the worker's body in the future. After improvements were made by adding trolley service tools, the way of working became more ergonomic so that the REBA score dropped to 2, which shows that some of the movements carried out were in the safe category or did not cause muscle injuries in the future. Therefore, the presence of bodily abnormalities that arise from work cannot be separated from the existence of supporting equipment to facilitate the removal of certain parts so as not to cause abnormal bodily effects. Planning for the procurement of a particular tool needs to be done as soon as possible so that workers do not suffer the effects of bodily abnormalities. In this way, the author took analytical steps using the Rapid Entire Body Assessment (REBA) method, which is the best solution to solve the problems that exist in this company to support workers so they can work all the time without any complaints about their bodies.

STBM is a comprehensive approach that not only includes sanitation infrastructure development, but also emphasizes changes in community behavior and sustainable waste management. Thus, in the implementation of STBM, the 3R Waste Disposal Site (TPS) is a key component in sustainable waste management. TPS 3R refers to waste management with the 3R principles, namely Reduce, Reuse, and Recycle. However, in this case Menur Pumpungan Village still does not have a 3R-based waste processing facility. So it is necessary to plan the optimal design of TPS 3R to be applied in the future and be able to make a significant contribution in efforts to realize Community-Based Total Sanitation. To calculate the number of TPS 3R services as the basis for design, data on the population in 2023 and the waste generation rate of 2.6 liters/person/day were used. Based on the calculations made, in an effort to support the implementation of the Community-Based Total Sanitation program. The construction of TPS 3R, which is planned to be able to serve the domestic waste processing of the entire Menur Pumpungan urban village community, is expected to reduce the amount of waste entering the landfill. The total land required for operational facilities is 511.85 m2 with a TPS 3R design consisting of a 440.85 m2 waste processing area and 96 m2 of other supporting facilities..

Ship stability is the ability of the ship to return to its original position from a tilt or tilt caused by external disturbances or forces (Kunaifi, 2016). Damage Stability is a calculation of ship stability where the ship experiences damage (leakage) in one of the compartments (Sawasono et al, 2019). The principle used in damage stability analysis is that if there is a leak on the ship, then the leak space is considered to have lost its buoyancy or added sea water entering as additional cargo (Hidayatulloh, 2018).
