ABSTRACT

The supply of fresh water for people who live on small islands but do not have a fresh water source is often a problem, especially regarding the selection of technology and raw water sources. So far, many people on the island who do not have a source of fresh water have to take water from a nearby island, or use rainwater during the rainy season. The use of technology that requires electrical energy and fuel will make the price of water expensive, so we need a fresh water supply technology that is easy to maintain and cheap in operational costs so that it can be done with local human resources and facilities. Pipe installation technology which is often used in gas and oil pipelines as well as electric cables requires special vessels which of course must be imported from other places, which will certainly have consequences for installation costs. If using this technology for installing fresh water pipes for domestic consumption purposes that are not business-oriented on a large scale, it is not suitable, so it is necessary to innovate so that pipe installation can be carried out at a lower cost which can also be installed by residents of the island, so that it will be easier for operation, maintenance and repair. The installation of an inter-island freshwater subsea pipeline using the TJ-19 method is very suitable because it does not require a special vessel and also does not require other sophisticated equipment, the installation can be carried out with a modified boat so that it can be used to install pipes more easily. The installation technique is to stretch the pipe in front of the boat for 100 m and at the end of the pipe, it is tied with a rope and given an anchor weight of 1,200 kg to maintain the coordinates of the pipe installation. Pipe installation is recommended when the maximum sea current speed is 0.8 m/s and the maximum wave height is 1 meter, so that the process of lowering the pipe can be carried out at the planned point.
