C Container terminals really need electrical energy in their operational activities which are used in cranes that lift containers, in buildings and site offices in the field, in lighting the container area, for transmitting data, and other utilities. pt. jict is required to provide the best service so as not to cause much loss. along with the activities of the container terminal which works 24/7 throughout the year, to maintain the continuity of its distribution a reliable electrical system is necessary. one of them is to anticipate work accidents by implementing k3 related to these accidents, one of which is electricity k3 to avoid electrical work accidents. the distribution substations st 15 that receive supply from pt. pln must have a k3 system for the safety and welfare of workers, especially in electrical k3. the causes of negligence and lack of understanding of occupational health and safety (k3) are the biggest factors in electrical accidents. almost all electrical power usage is directly carried out by electrical installations, which can cause electrical accidents. the purpose of this report is to analyze and apply the occupational health and safety system at the st 15 substation located at pt. jict is in order to form a workplace that is safe, comfortable and free from accidents and occupational diseases, so that workers can increase their work productivity in this company. the method used for the research is to directly review the field to collect data from substations, and then provide the application of the system that complies with electrical occupational health and safety based on legislation or electrical safety regulations in accordance with the indonesian national standard (sni) if there is a system that does not comply. the results of this research, which include an analysis in the form of a table of findings that either do not comply or already comply with electrical k3, can serve as a reference and assist workers in improving the electrical k3 system that is in accordance with indonesian national standards. this research can be used as a reference for workers and will facilitate the improvement of the electrical safety system that does not comply with indonesian national standards. the purpose of the research can be used by the company as a guide or guideline for the workforce in the field, in order to create good and proper occupational health and safety.
