This research was motivated by several laundries that use pressure cooker steam iron boilers for the ironing process. However, there are still users who find it difficult to estimate water level. If the water in the pressure cooker dries up or runs out whitout knowing it, then this can be dangerous and have a bad impact both on the user and in terms of the quality of the pot. So the aim of this research is to modify the pressure cooker steam iron boiler by adding a water level indicator whose function is to determine the water capacity during the ironing process, so that it is hoped that it can minimize work accidents. The method use is descriptive quantitative. From the design process, the tool was then tested to determine the starting time for using the iron using pressure variations of 15 psi, 20 psi, and 22 psi. From the research results, it was found that the design process was carried out through several stages, including the measurement process, drilling process, and assembly process. The test results started that the optimal pressure was 20 psi, because at this pressure the steam produced was optimal with a heating time of a 58 minutes.

This qualitative study aims to examine the implementation of risk management in hull insurance by collecting data through interviews with the risk management staff of Asuransi Mitra Pelindung Mustika Ltd. The findings revealed that this company has applied the risk management process, including risk identification, risk analysis, risk evaluation, risk control, risk transfer through other insurance policies, monitoring, and review. The company covers losses due to fire, explosion, violent theft, piracy, accidents involving installations, collisions with aircraft or similar objects, earthquakes, volcanic eruptions, lightning strikes, accidents during loading or refuelling, boiler explosions, machinery shaft breakage, or latent defects in the machinery, hull, or frame of the insured vessel. Asuransi Mitra Pelindung Mustika Ltd. also compensates for losses due to the negligence of the captain, officers, or crew of the insured vessel, as well as the shipyard. Time to process the claim becomes a significant challenge in fulfilling the insured's rights in the claim for the BG. TRG 06 vessel because it takes up to 14 days to gather all the necessary documents. This company will cover all repair costs and labor expenses, with an estimated total value of IDR 7,611,100,000.00.

From this study, the automatic electric oil heater can be used to adjust the temperature value and the automatic electric heater will be able to turn off automatically according to the setpoint temperature value determined through a smartphone device or IoT program. Monitoring can also be done with the app, as well as being able to view temperature values directly through the LCD. This tool is in the form of an electric heater that will be used to heat ship fuel automatically and is more practical and efficient. It is also easier to maintain than a boiler on a ship. The design of this tool is based on accurate calculation of temperature values, with which the process of heating up fuel becomes faster. From the results of this study, a heat sensor that can read the temperature value and the buzzer will sound and the device will automatically turn off if the temperature has reached a specified setpoint. This research was carried out when the ship was about to make a departure to find out the temperature in the heating of the fuel on the ship. Testing Design of an automatic electric oil heater as a replacement for IoT-based thermal oil boiler on this bulk carrier ship, it can be known the disadvantages and advantages of this tool, testing can be done by putting oil into the electric heater, then in a short time the oil will heat up quickly, and the tool will be able to turn off automatically and the buzzer will immediately turn on when the heat has reached the specified temperature. In the temperature setting, it can be set in a smartphone or an app that can adjust the temperature and turn off the appliance from a considerable distance. However, the application must use the internet network and cannot be accessed locally, the use of IoT requires devices and smartphones to be connected to the internet.    

HIRARC is a document that contains hazard identification, risk assessment and risk control in order to reduce the occurrence of occupational safety and health disturbances. The type of research used is qualitative with a descriptive approach. The research aims to explain the value of the risks contained in each work area by describing the work safety analysis process by determining the level of likelihood and severity of each risk. Based on interviews and observations conducted by researchers in the Boiler section of PLTU Nii Tanasa Kendari, there are several potential dangers ranging from physical, mechanical, chemical, electrical, to ergonomic dangers. The results of the analysis of potential hazards show a low risk of 9 types of danger, a moderate risk of 7 types of danger, a high risk of 8 types of danger.The controls used are technical engineering such as providing fire extinguishers and first aid kits, installing handrails and guardrails to anticipate falls from heights, and providing insulation and dampening for equipment that is at high risk of causing work accidents. Administrative controls such as providing work instructions and SOPs, cleaning work environment areas and using PPE.
