Traditional wooden motorboats are ships that are built traditionally based on the experience of the builder without a basic design process like modern ships. The sizes of traditional wooden ships are usually small and are mostly used as fishing vessels, passenger ships and inter-island cargo ships, especially in eastern Indonesia. Traditional wooden motor boats have become a means of local transportation to serve shipping needs in the regions and as a means of local transportation. Sailing certainly has various problems which can be caused by weather factors, the condition of shipping lanes, other ships, and things beyond human capabilities, which can cause shipping disruptions and even cause emergencies. Emergency means a situation outside normal conditions that occurs on board a ship which has a tendency to endanger human life, property, objects and the environment where the ship is located. One way to anticipate emergency events is to provide safety equipment. IMO (International Marine Organization) as a maritime world organization issued SOLAS (Safety of Life at Sea) which contains provisions regarding what safety equipment is on board ships such as Life Jackets, Ring Buoys and Fire Extinguisher. However, in fact, fulfilling the safety equipment requires independent costs from traditional motorboat owners so there is a priority in fulfilling the safety equipment. Based on the results of the Analytical Hierarchy Process calculations in priority fulfillment of safety equipment with the final result of 36.6% Life Jacket, 30.8% Ring Buoy and 33.6% Fire Extinguisher. With these results, ship owners can determine their priorities in anticipating future emergencies

In the world of the PLTU industry, the need for material, especially the need for the sapot process and conveyor repairs, occurs in the world of PLTU, which is installed on the conveyor construction and when connecting materials, different grades are often used and this often occurs in the field during the process of combining plates with different grades. on the sapote. and for installing the plate on the sappot, use grade A and the plate that is often used is the plate for the machine foundation with grade B on the sappot material using low carbon grade A steel. In this research report, welding is carried out and combined with grade A steel which is usually used for sappots. the conveyor is combined with low carbon grade B steel in the construction of the PLTU sapot. Where welding is carried out 3x why this needs to be done is because to know the characteristics of low carbon grade A steel and low carbon grade B steel, whether the characteristics are the same or not because they are used in When grade A steel material runs out in the industry, the testing process uses 3 tests, namely to determine NDT testing (Non Destructive, test), tensile testing, and micro testing for the testing process.
