Abstract

This research contains the coating repair process and costs required for a fishing boat with a hull length of 11 meters, starting from docking and cleaning old paint, with the aim of finding out the amount of materials neededand coating costs needed for a wooden boat. To determine how much paint should be used for wooden ship repairs. Qualitative description method, which is included in the qualitative research category. This writer aims to reveal events, phenomena, variables, situations and circumstances, facts that occur. Because almost all ship building materials are wood. In order for paint to meet the specified requirements, it must comply with the specified painting process, pre-inspection, surface preparation, paint preparation, and paint application. For thisreason, it is necessary to know the various types of painting techniques that must be prepared before carrying outthe process of painting the ship's hull. The coating process on the ship's hull uses 2 different types of paint, namely the Avian brand for base paint and the Avian moustrial and marine coating brand for color paint. Where each part of the ship is covered with 2 parts. i.e. base paint, the result is 10 liters with a hull area of 48m2. With a totalcost of Rp740,000, the yield of color paint was 9.6 liters, namely Rp816,000. So from this research it can be concluded that using base paint and anti-fouling paint is more profitable because it has been calculated and you can buy the right paint without having to have any leftovers. And the usage time is longer because the paint thickness is according to the specified one.

Abstract

The cooling system is a system that functions to maintain the engine temperature at a certain temperature in accordance with the specified design so that the diesel engine can operate continuously. For cooling of a diesel eninge. Fisherman Village of Ngimbo Village is a coastal area which is an area full of marine potential, the local community on average works as fisherman. This research was conducted using the interview method with fisherman, especially those who own boats. The questionnaire was addressed to 10 fisherman. The results of the study show that fisherman’s boats in Ngimbo Village use seawater cooling, in wich fisherman modify the cooling system of the Dongfeng brand diesel engine using a head exchanger for fishing motor boats aiming for cooling water temperatures in the 60°C - 90°C range and replacing the open cooling system method which are considered less efficient and have many negative impacts on the engine such as corrision and the temperature of the cooling water in the water jacket is brought to the specified standard. Special orecautions must be taken to accommodate open systems. For example, some engines can be equipped with an aftercooler as well as cleaning the core of the corrosion-resistant pipe. Aftercoolers from round tubes are designed lik fin plates and can be disassembled for cleaning, so they are ready for use in open systems.
