Abstract
Atmospheric water generator (AWG) merupakan suatu sistem kondensasi untuk mendinginkan uap air dalam udara hingga berubah wujud menjadi air tawar agar bisa dikonsumsi. Alat ini mampu menyediakan suplai air tawar secara kontinu dalam lifeboat selama menunggu proses penyelamatan saat harus mengevakuasikan diri keluar dari kapal ketika sedang berlayar. Namun pengoptimalisasian perlu dlakukan lantaran alat tersebut baru mampu menyuplai air tawar sebanya 7,6 L/hari selama pengoperasian 24 jam penuh untuk 20 orang penumpang dari kapasitas lifeboat yang direncanakan. Pada penelitian ini dilakukan uji eksperimentasi menggunakan variasi fluida kerja pada rangkaian sistem untuk meningkatkan peningkatan peforma alat supaya bisa menghasilkan air hasil kondensasi yang mencukupi untuk suplai semua penumpangnya. Dalam penelitian ini bertujuan untuk melihat flida kerja yang paling optimal untuk diimplementasikan pada AWG dan bagaimana peningkatan peforma yang dihasilkan Pamilihan variasi fluda kerja yang hendak diuji didasari pada beberapa parameter seperti kepebilitas komponen alat dan jenis/karakteristik fluida kerjanya. Fluida kerja yang akan di uji termasuk golongan refrigeran sekunder karena mampu mendistribusikan kalor tanpa harus merubah fasa dari fluida kerja, yaitu larutan etilen glikol, larutan propilen glikol, dan larutan kalsium klorida. Ketiga larutan tersebut diuji dengan konsentrasi yang sama sebanyak 50%. Dari hasil pengujian didapatkan larutan etilen glikol yang emiliki nilai efisiensi panling tinggi, yaitu sebesar 0, 49093% dengan hasil air tawar sebanyak 4,5 mL/jam.

Atmospheric water generator (AWG) is a condensation system to cool water vapor in the air until it turns into fresh water so that it can be consumed. This tool is able to provide a continuous supply of fresh water in the lifeboat while waiting for the rescue process when it has to evacuate itself out of the ship while sailing. However, optimization needs to be done because the tool is only able to supply fresh water as much as 7.6 L / day during a full 24 hour operation for 20 passengers from the planned lifeboat capacity. In this study an experimentation test was carried out using variations in the working fluid on a series of systems to increase the performance of the device so that it could produce enough condensed water to supply all of its passengers. In this study the aim is to see the most optimal working environment to be implemented on the AWG and how the performance improvement produced The selection of employment variations to be tested is based on several parameters such as the reliability of the tool components and the type / characteristics of the working fluid. The working fluid that will be tested is classified as a secondary refrigerant because it is able to distribute heat without having to change the phase of the working fluid, namely ethylene glycol solution, propylene glycol solution, and calcium chloride solution. The three solutions were tested with the same concentration as much as 50%. From the test results obtained ethylene glycol solution which has a high panling efficiency value, which is equal to 0, 49093% with fresh water yield of 4.5 mL / hour.
