Introduction
The potential of Indonesia's marine fisheries resources is 6.6 million tons / year, but only a portion of which can be captured by Indonesian fishermen is ± 4.7 million tons / year, partly stolen by fishermen of neighboring countries. This is due to the limited number and large size of fishing vessels in operation. According to the Head of the Maritime and Fishery Human Resources Development Agency, the Indonesian Ministry of Maritime Affairs and Fisheries estimates that the potential number of fish resources allowed in the Indonesian fisheries management area reaches 12.5 million tons [6].
One area that has potential for capture fisheries is Pakuhaji District, Tangerang Regency, Banten Province. Pakuhaji Subdistrict has a coastal area which is directly facing the Java Sea. This region has a coastline of ± 6 (six) kilometers. This region has a Cituis Fish Landing Base (PPI), precisely located in Surya Bahari Village.
Surya Bahari Village Area, Pakuhaji District, Tangerang Regency has great potential for capture fisheries. In this region, there is a Fish Landing Base (PPI) which is capable of anchoring fishing vessels up to a maximum size of 10 Gross Tonnage (GT) vessels. The fishing boat with a size of 10 GT is intended for inland waters and archipelago waters. In order to improve the capabilities of the fishermen in the Pakuhaji * Corresponding author : bambangsudjasta@upnvj.ac.id District, fishing vessels need to be built that are suitable for this region and are energy efficient. If the design / construction and construction of fishing vessels can be realized, then in turn the welfare of the fishermen in this region will increase [1].

The designed ship is planned to use materials that are generally used to build ships with a relatively small size [8]. The design of the ship includes determining the basic size, making line drawings, preparing general plans, construction designs, stability diagrams, engine power, solar energy, and tonage.
To meet the criteria of energy saving and environmentally friendly, the electricity generating equipment for lighting at night and other purposes, the designed ship is planned to use solar energy [4].
The length of the PPI Cituis jetty is approximately 150 meters, with a pool depth of less than 70 cm. Can accommodate ± 10 fishing vessels be measuring an average of 10 GT. Capture land area for catching fish is not more than 5 hectares. From the limitations of the available landing facilities, a fishing boat can be designed for a maximum of 10 GT. The problem of electrical energy for lighting purposes during nighttime operations and other electricity needs is a separate problem, which has so far been using a generator constrained by the limited supply of expensive fuel oil. The use of stum storage batteries is identified to be easily damaged due to frequent loading and unloading at the time of filling the strum. To overcome the problems of electrical energy with the alternative use of solar panel installation as a provider of electrical energy as a substitute for the previous electrical energy system.
To design a fishing vessel that will be operated, especially in the waters of Tangerang Regency, there are certainly some things that become the basis of reference. One such reference is the criteria / port class [7]. Spatial (zoning) processing / development of the fishing industry

The purpose of this study is to design or design a 10 GT fishing vessel for the territorial waters of Pakuhaji District, Tangerang Regency. This research is expected to provide benefits in getting the shape and size of fishing vessels that are suitable for the territorial waters, providing input to the Tangerang Regency Government, especially the Fisheries Service in the context of increasing the empowerment of fishing communities. Fishing Vessel (Fishing Vessel) is a type of fishing vessel specifically used for catching fish, including storing, storing, cooling or preserving [12]. Fishing gear that is only allowed to be used in waters around the ZEEI line is a type of trawl and gill net.
The Fish Landing Base (PPI) is a Type D. fishing port. This fishing port has a land area of 2-5 Ha, and is designed to serve fishing vessels measuring 3 -10 GT. This fishing port can accommodate 6 ships or 60 GT at a time. This fishing port serves fishing vessels operating in coastal / inland waters and archipelago waters [3].

Reasearch Flowchart
Research methods in the Utilization of Solar Energy on 10 GT Fishing Vessels as Alternative Electricity Facilities at PPI Cituis Tangerang Regency include the research flow and a description of the research flow as shown in Figure 2.

Cituis Fish Landing Base (PPI)
The management and guidance of PPI Cituis is under the Tangerang Regency Maritime and Fisheries Office. The role of PPI Cituis is to advance capture fisheries in the area which include aspects of production, processing and marketing. Its operation is greatly influenced by the catch landed. The capacity of the PPI Cituis facility will affect the smooth operation of port activities to fulfill its functions optimally. PPI Cituis is one of the seven PPI in Tangerang Regency that contributes to the Tangerang Regency PAD. The facilities, production and requirements of PPI Cituis are described as in table 3 below. ± 60 block / day Almost all PPI Cituis facilities are considered to be adequate, except for the capacity to accommodate vessels that need to be added, because sometimes the ship that will lean must wait in line.

Main Dimension
A general plan is presented to explain the design of a 10 GT fishing boat with a single engine (1) 54 HP diesel engine and can operate on coastal waters 10 miles from Pakuhaji beach for 10 hours.

Velocity and Distance Radius
Official speed at 90% Maximum Continuous Rating (MCR) with Sea Margine 15% main engine, with two thirds (2/3) fuel & fresh water capacity, 6 (six) people, on the basis of a clean / slippery hull, 8.00 knots in a state of calm water. At operational time with a full speed of 7.50 knots the condition of the engine is loaded at 90% MCR able to sail a total cruise distance of 80 Nm with 10 hours endurance.

Construction
This fishing vessel is made with wood raw material. It is intended that the cost of shipbuilding is relatively cheap but the strength of construction is also relatively better, considering that in PPI Cituis the leaning area is rather narrow so that it often clashes between one ship with another. In the manufacture of wooden ships there are several things that need to be considered, including the composition of good quality materials, both for Lunas (keel), Bottom, Hull, Ivory / framework and other parts. In addition to the composition of the thickness of the material used is also a matter that needs attention [10]. All materials and equipment used for the manufacture of fishing vessels are new, with materials that have good quality test materials and are specifically used at sea. The material used for the hull structure uses wood material with a minimum thickness of designation as follows : Lunas (keel), Base (Bottom), Hull (Hull), Ivory / Framework (Frame), Deck Floor (Deck), and Upper Building (Deck) Wheelhouse).

Tonnage
Tonnage is the volume of space on a ship with a Register Tonnage (RT) unit, where 1 RT = 100 ft 3 or equivalent to 2.83 m 3 .
Determination of ship GT according to the method of domestic measurement, is calculated in accordance with the provisions in the Decree of the Director General of Sea Transportation No. PY.67 / 1 / 16-02, using equation (1).
The value of 0.25 is the conversion value from cubic meters to tons of registers. V = is the total contents of the room below the upper deck plus the rooms above the top deck that are perfectly closed measuring not less than 1 cubic meter.

Electric Power from Solar Panels
The generated solar cell voltage will be used by the charge controller to charge the battery [11]. To turn on the load of AC devices (alternating current) such as navigation lights, television, radio, communication devices, etc., the battery current is supplied by the inverter [5]. Installation of solar power plants requires planning regarding power requirements, namely the amount of usage, the number of solar panels, the number of batteries [9]. The number of solar panels / solar cells needed, we count one panel to 100 Watts (calculation is 5 hours maximum solar power), The need for solar panels: 495 / (100 x 5) = 1 solar panel.
The number of solar panels / solar cell needed, one panel we count 100 Watt (calculation is 5 hours maximum solar power), The need for solar panels: (1980/100 x 5) = 2 solar panels.

CONCLUSION AND SUGGESTION
1. From the results of comparing the basic sizes and equipment, as well as calculating the electrical needs for the ship, the conclusion is obtained as a specification of the 10 GT fishing vessel as below.
