Every fishing boat owned by fishermen in the Muncar Harbor area of Banyuwangi is always decorated. In addition to beautifying the ship, they also provide enthusiasm for work. Various decorations used include the shape of the dome of the mosque and the shape of a butterfly. Although technically all ornaments do not support their safety at sea. Accidents, namely the collision of traditional fishing vessels by large commercial vessels often occur. because the area of operation of traditional fishermen is the trajectory of large commercial ships. Many accidents occur because the presence of fishing boats is not detected by commercial vessels. because most traditional fishing boats are made of materials that do not reflect the radar signals of large vessels. For this reason, it is very necessary to install a reflector radar, which is a passive radar that serves to increase the object’s Radar Cross Section value. This radar can be mounted on fishing vessels so that the reflected energy from this radar reflector can be recognized by large ships. This article describes designs that are in demand by traditional fishermen in the Muncar area of Banyuwangi.

The ship electrification process is the process of installing or providing electric power to supply all the electrical power needs for ships. In general, main electricity supply will be provided, and emergency supplies in the form of batteries or emergency generators that are able to survive supplying emergency loads such as navigation equipment, navigation lights, and emergency lighting for about 3 hours. Another consideration in the electrification process on fishing vessels is also aimed at reducing dependence or even replacing conventional fuel. Of course, not all machines or equipment that are usually operated with conventional fuel can be directly replaced with electrical energy. The implementation of electrification on fishing boats takes into account the technological and cultural aspects of fishermen so that not all of them will be directly replaced by electrical energy.

As a city crossed by rivers, Surabaya has the potential for attractive water tourism. Kalimas is one of them. Kalimas is a river that divides Surabaya. Kali Mas is a tributary of the Brantas River. This main river flows from Mojokerto as its headwaters, then flows to the northeast, empties into Surabaya, and ends in the Madura Strait. Muara Kali Mas has been Surabaya's traditional port for centuries. This port became the gateway to the capital of the Majapahit Kingdom (in Trowulan), and became part of the Surabaya people's battle against the allies before November 10, 1945. In various countries, river tourism has developed. Not only for city residents, but has become part of the State's tourism. One example is in Italy, namely tracing the river canals in Venice in Italy. Everything is described so well that everyone who comes wants to try it. Experiences and interesting photo documentation make river tourism an opportunity to develop. River tourism can be a potential alternative for Surabaya residents. Become a means of recreation or further developed into a tourist vehicle of national and even international standards. An important means of water tourism is a boat. Tour boats were developed to support the success of this tour. This article discusses the electrical installation for tourist boats that will be used on the Kali Mas River. Its power source is taken from diesel engines and also from solar panels that are capable of generating electricity.

The economic condition of the coastal communities of East Java, especially in Banyuwangi, is strongly influenced by the tourism and fishing sectors. This condition needs to be developed with supporting facilities such as the procurement of fishing vessels. Procurement of fishing vessels must be designed with a feasibility study on vessel operations. In general, coastal conditions have shallow water depths and are often used by coastal communities for lobster cultivation. The supporting fishing vessels must be able to maneuver properly and not damage the ecosystem so that the existence of coral reefs is maintained. The fishing boats that support lobster aquaculture are designed with good maneuverability by taking into account the speed, the result of the waves formed and the capacity of the ship. The results of the design of fishing boats supporting lobster cultivation obtained that the main size of the ship is 13.00 meters long, 3.00 meters wide and 0.8 meters draft with a speed of 12 knots, reaching a designed mileage of 30 km in shallow water operational conditions
