Abstract

English

The need for hot water on a ship is one of the facilities that must be obtained by the crew while carrying out their duties on the KM. Meratus Karimata is one of the ships that provide hot water as a facility for crew members. The heating system on this ship still uses the EHHW (Electric Heating Hot Water) heating system which will then be changed to the HPWH (Heat Pump Water Heater) system. This hot water need is based on the MLC (Marine Labor Convention) regarding the provision of recreational facilities on deck accommodation. The provision of hot water needs to be calculated and designed. The first thing to do is to calculate all distribution support components. Then the data for the needs of pumps with a power of 0.504 Kw, valves, shower taps, sink taps, pipe connections, and SCH 40 pipes with a diameter of ¾ "and 1" are obtained. After that, the design is carried out using software assistance. After the design is carried out, the calculation of component costs is carried out with details of the valve price of IDR 10,129,000, pipe IDR 5,186,000, pipe connection IDR 1,751,000, supply pump IDR 1,150,000, HPWH 95,300,000. The price of EHHW and HPWH is a difference of IDR 21,300,000, which is more expensive for HPWH. However, in the calculation of fuel consumption, HPWH is more efficient with HPWH fuel consumption data of 0.11 liters/hour at a cost of Rp.1,249 / hour, while fuel consumption for EHHW is 0.77 liters/hour at a cost of Rp.10,116/ hour.

Kebutuhan air panas di kapal merupakan salah satu fasilitas yang harus didapatkan oleh ABK (Anak Buah Kapal) selama menjalankan tugasnya di kapal. KM. Meratus Karimata merupakan salah satu kapal yang menyediakan air panas sebagai fasilitas untuk ABK. Sistem pemanas pada kapal ini masih menggunakan sistem pemanas EHHW (Electric Heating Hot Water) yang kemudian akan dirubah dengan sistem HPWH (Heat Pump Water Heater). Kebutuhan air panas ini didasari oleh MLC (Marine Labour Convention) mengenai penyediaan recreational facilities pada akomodasi deck. Penyediaan air panas ini perlu dilakukan perhitungan dan perancangan, yang pertama dilakukan yaitu perhitungan seluruh komponen penunjang pendistribusian. Kemudian didapatkan data kebutuhan pompa dengan daya 0.504 Kw, valve, keran shower, keran wastafel, sambungan pipa, dan pipa SCH 40 dengan diameter ¾” dan 1”. Setelah itu dilakukan desain perancangan dengan menggunakan bantuan software. Setelah dilakukan perancangan, lalu dilakukan perhitungan biaya komponen dengan rincian harga valve Rp 10.129.000, pipa Rp 5.186.000, sambungan pipa Rp 1.751.000, pompa supplay Rp 1.150.000, HPWH 95.300.000. Harga dari EHHW dan HPWH ini terdapat selisih Rp 21.300.000 dimana lebih mahal HPWH. Tetapi dalam perhitungan konsumsi bahan bakar lebih hemat HPWH dengan data konsumsi bahan bakar HPWH 0,11 liter/jam dengan biaya Rp 1.249/jam, sedangkan konsumsi bahan bakar untuk EHHW 0,77 liter/jam dengan biaya Rp 10.116/jam.
