Optimization of the Electrical System on the Hiu Macan 3 Surveillance Vessels in Support of Supervision in Eastern Indonesia

Hiu Macan 3 surveillance vessel is one of the Directorate General of Marine and Fisheries Resources Surveillance's supervisory vessels which plays an important role in marine surveillance in Eastern Indonesia. In support of monitoring activities, a reliable electrical system is needed and very careful maintenance methods are needed. To support these activities, a generator usage schedule is applied, either during operation or while leaning at the port. The main generator can be used to supply all the ship's electrical needs. The use of the main generator can be optimized to supply all the ship's electricity needs because the daily load percentage is still 33.79%, although this is still within the normal limits. If there is a problem with the main generator, a backup generator can be used, but only for lighting, navigation, and auxiliary engines. The maintenance schedule is required by performing daily, weekly, monthly, and overhaul maintenance. From the analysis carried out, the largest total daily electric power is 41.56 kVA and electrical energy is 310,676 kWh.
