Basically a ship has a variety of conditions, namely cargo handling, anchoring, maneuvering, and sailing its requires large electricity consumption. The quality of the voltage is not good will cause damage to electrical equipment on board. Disturbances that occur in electrical system of MT. X may result in a decrease in the performance of existing electrical equipment on the vessel and affect a certain condition as in loading-unloading conditions the time required for loading and unloading becomes longer due to interference with the electrical system. The MT.X tanker system has 5 (five) main busbars: BUS 1, FEEDER PANEL, DSB 2, DSB 3 & 4, and DSB 6. The MT tanker. X has a generator of 3 units with a power of 680 kw each, a frequency of 60 hz and a voltage of 450 V. Transient disturbance analysis under loading-unloading condition occurs transient response due to starting ballast pump where the voltage rises and then drops within 0.5 seconds with the highest value of 100.44% at 4.01 seconds and the lowest value is 99.50% to 4.81 can then reach steady state conditions at 99.9%, which does not exceed the IEEE standard limits. In harmonic disturbances under loading-unloading conditions, in the feeder panel connecting the harmonic source with load at the 5th order, the value of VIHD is 8.77%, which exceeds the IEEE standard of 5%. While the value of VTHD in loading and unloading conditions also exceeded the predefined standard limits. After installation of the filter, it can be seen that the value of VIHD at the 5th order in loading-unloading condition decreased to 3.6% after the installation of filter on feeder panel, or equal to decrease as much as 5.17%. The decline in the value of VIHD has fulfilled the IEEE 519-2014 standard of 5% on each individual order. Meanwhile, VTHD value in loading-unloading condition also decreased, from 11.18% to 7.02%.

Electric propulsion system is ship propulsion system using electric motor to replace performance of main engine. Submersible ships use DC motor as electric propulsion system because DC motor has advantages of speed control and lower propulsion noise when submersible ship is at submerge condition. Design of electric propulsion system is using two DC motor that are connected in series. Battery and generator as its power supply. Designs of electric propulsion system that will be reviewed here are using ohmformer and without using ohmformer. Those designs will be simulated using MATLAB Simulink. The results of the simulation are that the design using ohmformer is greater in speed and power than without using ohmformer. Because of using ohmformer can control input voltage of DC motor that use generator as its power supply. Meanwhile, ohmformer-less design has constant input voltage that use battery as its power supply. Next, design of using ohmformer can be used for silent run (low speed), sailing run (medium speed) and quick run (high speed). Then design of without using ohmformer can be used for sailing run (medium speed).

Induction motor is an Alternating Current Electric Motor (AC), this motor most widely used. There are two types of rotor on three-phasess asynchronous motor, the squirrel-cage rotor and the slip ring rotor. Every motor has its own characteristic, it have been affect the used of the motor. In this research is aiming to know three-phasess asynchronous slip ring motor performance on unloaded and loaded condition. On its condition, the variation resistance starting from 0(ohm) - 25(ohm). The results of three-phasess asynchronous slip ring motor on unloaded condition having maximum output power 58 W and maximum torque 0.22 Nm in 25(ohm) of resistance. While in the condition loaded having a maximum Pin 131,5 W, maximum Pout 109,31 W, maximum torque 2,08 Nm and maximum efficiency 95%. The analysis was done by knowing the relation between torque vs speed and efficiency vs load. The result shows that the increasing of motor speed have been give affect the decreasing of motor torque in according with the torque formula. In the other result, it can be seen that increasing of the load, efficiency have been increase.

The rapid development of maritime technology in the world to make Indonesia are also increasingly taking the development of maritime technology, such as in a Submersible Vehicle one is degaussing system, this technology should be owned by the vessel so that the vessel can avoid dangerous explosive equipment contained in the sea. Degaussing system is a system that is in use on the metal parts or electronic devices that are at risk of a magnetic field. This system is used to prevent the vessel from dangerous equipment in the sea which can trigger an explosion and the damage that utilize magnetic fields as a metal-detection sensor when the boat was doing dives. To the authors will plan the design degaussing system, and calculating the system in order to reduce the magnetic properties of the Submersible Vehicle which were obtained by the use of Coil Degaussing along 214,5 meters, a diameter of 0,2, with 500.000 coil that will generate a current of 0,0157 Ampere's 0.0787 Tesla generates a magnetic field.

Electric propulsion is the ship system using propulsion motor to replace performance of main engine. The application of diesel engine as propulsion system have some problems and weaknesses such as diesel engine unability to operate when submersible vessel is operating under sea. To overcome that problems in submersible vessel, alternative solution of ship propulsion is required. DC Motor can be used as this alternative solution. Submersible vessel use electric propulsion system with DC Motor because DC Motor has advantages of easy rotation setting and does not cause noise when submersible vessel is diving. This bachelor thesis will study the application of DC Motor as an electric propulsion system on submersible vessel with length 59,57 m in series and parallel circuit by simulation using MATLAB software. The simulation data obtained are rotation and torque of DC Motor. From these simulation, it can be concluded that parallel circuit rotation is greater than series circuit rotation. It caused the greater speed and lower power in parallel circuit.

The port is one of the supporting infrastructures for sea-transportation carrying goods and passengers. The function of port is important in supporting the transportation system to develop economic, social, and eduaction with sea-trading as booster. Crane is device which use to lift or move heavy loads and commonly was used in ports for container loading - unloading process. This research will create automatic stacking crane prototype with an Arduino Mega 2560 as controller. There is a lack of this design is the incoming voltage to the motor sourced from this microcontroller module is 5 V. In hence, the spindle motor is not optimal. In addition, there are still many input response procedure was not appropriate.

This paper concern about design ACOS with PLC system. The supply of electricity will move from the main generator to the battery when the main generator lost one phase, and the power supply will switch to the emergency generator when the voltage in accordance with the emergency generator working voltage AC electrical equipment on board is 380VAC. Electricity supply shall not move directly from the emergency generator to the main generator but to the battery first to prevent damage to the AC electrical equipment on board. Transport time for the system for 30 seconds ACOS equipment in accordance with the ICC and SOLAS regulations which require the transfer of under 45 seconds. ACOS equipment can be used in real conditions on the ship because it has phase failure, under voltage and over voltage protection and a relay as an indication for the transfer of command power supply automatically.
