Abstract
Kapal patroli yang memiliki panjang 30,9 meter, lebar 8 meter dan memiliki ABK 22 orang. Untuk menunjang operasi pengamanan wilayah perairan Indonesia. Kapal patroli bekerja selama 24 jam dalam 3 hari. . Air tawar dalam kapal dapat digunakan untuk kebutuhan consumable drink water, sanitary, dan air pendingin. Dalam kapal, air tawar adalah salah satu komponen yang membuat DWT menjadi besar. Apabila harus membawa air tawar dari darat lalu diletakkan di fresh water tank akan menambah DWT. Maka dianalisa untuk penambahan reverse osmosis untuk menjernihkan air laut agar tidak perlu membawa air tawar. Dengan adanya system reverse osmosis membutuhkan head yang tinggi agar dapat menjernihkan air laut. Perencaan scenario pompa untuk mencapai head yang dibutuhkan menggunaan konfigurasi pompa sentrifugal seri dan juga perencaan peletakan karena space kamar mesin pada kapal patroli sangat terbatas. Dari perhitungan kebutuhan air tawar dalam 1 hari adalah 2250 liter, dan ditentukan kapasitas reverse osmosis sebesar 345 liter/hour dengan head 105 m, pompa general service di pasang konfigurasi seri untuk memenuhi head. Pompa sentrifugal tunggal memiliki head 54 m dan setelah di pasang konfigurasi seri head menjadi 105 m. peletakan reverse osmosis tepat diatas tangki fresh water tank pada frame 6 - 7 bertujuan untuk memudahkan air hasil penjernihan agar tidak membutuhkna pipa yang terlalu panjang. Kemudian peletakan pompa general service pada frame 16 – 17 dekat pada seachest.

The patrol boat is 30.9 meters long, 8 meters wide and has a crew of 22 people. To support security operations in Indonesian waters. Patrol boats work 24 hours in 3 days. . Fresh water in ships can be used for consumable drink water, sanitary and cooling water needs. In ships, fresh water is one component that makes DWT large. If you have to bring fresh water from land and then put it in the fresh water tank, you will add DWT. Then it is analyzed for the addition of reverse osmosis to purify seawater so there is no need to bring fresh water. With the existence of a reverse osmosis system requires a high head in order to clear the sea water. The planning of the pump scenario to reach the head is needed to use a series of centrifugal pump configurations as well as laying planning because the engine room space on patrol boats is very limited. From the calculation of fresh water needs in 1 day is 2250 liters, and determined the reverse osmosis capacity of 345 liters / hour with a 105 m head, the general service pump is installed in a series configuration to reach the required head. A single centrifugal pump has a 54 m head and after installing the head series configuration it becomes 105 m. reverse osmosis laying just above the fresh water tank in frame 6 - 7 aims to facilitate the purification of the water so that it does not need a pipe that is too long. Then lay the general service pump at frame 16-17 near the seachest.
