<p><em>Maintaining a Fresh Water Generator from the loss of vacuuming means getting the best fresh water production process. The balance of the heated substance and the heater measurement inside the evaporator could effect on the steam result or even could influence the steam process. There are many factors that could cause the loss or the decreasing of vacuuming when operating Fresh Water Generator, such as system leakage, the lack of sea water volume used for vacuuming, the balance of water ejector capability to maintain the steam volume inside Fresh Water Generator, the brine ejector capability to maintain the unused brine water and condension water being exhaust of Fresh Water Generator. </em></p><p><em><strong>Keywords</strong>: Condenser, Evaporator, Ejector, Ejector Pump</em></p><p>Menjaga serta mempertahankan kondisi Fresh Water Generator dari kevakuman merupakan hal yang harus selalu diperhatikan secara baik,dengan tujuan untuk mendapatkan proses produksi air tawar secara optimal.

The Way

Fresh water is one of the primary needs on board. Shortage of fresh water on board, has a considerable risk, and to overcome the problem of lack of fresh water, commercial vessels are generally equipped with fresh water generators where the aircraft works with the process of evaporating seawater in the evaporator and seawater vapor is cooled with the way condensation in the distillation plane to produce fresh water. The fresh water genertaor parts are Evaporator, Condenser, Demister, Water ejector, Ejector Pump, and Destillate Pump. Then the Cause of Declining Freshwater Production in Fresh Water Generators is a decrease in fresh water production in fresh water generators. As for how to overcome so that the production of fresh water produced by fresh water generators does not decrease ie when the evaporator plate is cleaned, make sure the gasket on the plate must be in good condition, then cleaned from the crust attached to the plate, once every six months the nozzle and diffuser ( throwers) are removed and examined. And check the ejector pump for leaks and from corrosion such as impellers, casings, rings and shafts. In generating data the author uses descriptive research that is used to find the broadest possible knowledge of the object of research at a particular time. Descriptive research is research whose purpose is to explain or describe an event, condition, object whether a person, or everything related to variables that can be explained using either numbers or words. Keywords : Fresh Water Generator, Evaporator, Ejector Pump Air tawar merupakan salah satu kebutuhan primer di atas kapal. Kekurangan air tawar di atas kapal, mempunyai resiko yang cukup besar, dan untuk mengatasi masalah kekurangan air tawar, kapal-kapal niaga pada umumnya dilengkapi dengan fresh water generator dimana pesawat ini bekerja dengan proses menguapkan air laut di dalam evaporator dan uap air laut didinginkan dengan cara kondensasi di dalam pesawat destilasi sehingga menghasilkan air tawar. Bagian-bagian fresh water genertaor adalah Evaporator, Kondensor, Demister, Air ejektor, Pompa ejektor, dan Pompa destillate. Kemudian Penyebab Menurunnya Produksi Air Tawar Pada Fresh Water Generator adalah menurunnya produksi air tawar pada fresh water generator. Adapun cara mengatasi agar produksi air tawar yang di hasilakan fresh water generator tidak menurun yaitu pada saat plat evaporator dibersihkan, pastikan gasket pada plat harus dalam kondisi baik, kemudian dibersihkan dari kerak-kerak yang menempel pada plat, setiap enam bulan sekali nozzle dan difuser (penyembur) dilepas dan diperiksa. Dan periksa pompa ejektor dari kebocoran dan dari korosi seperti impeller, casing, ring, dan shaft. Dalam menghasilkan data penulis menggunakan penelitian deskriptif yang digunakan untuk menemukan pengetahuan yang seluas-luasnya terhadap objek penelitian pada suatu masa tertentu. Penelitian deskriptif adalah penelitian yang tujuannya untuk menjelaskan atau mendeskripsikan suatu peristiwa, keadaan, objek apakah orang, atau segala sesuatu yang terkait dengan variabel-variebel yang bisa dijelaskan baik menggunakan angka-angka maupun kata-kata.

In this work, an atmospheric water generator (AWG) system called the medium-scale AWG (MSAWG) was designed, fabricated, and tested in Universiti Sains Malaysia (USM) under the outdoor tropical climate conditions of Malaysia to investigate the amount of fresh water production in successive periods of 24 h. The MSAWG consisted of 18 thermoelectric cooler (TEC) units, 18 internal finned heat sinks, 18 external finned heat sinks, 18 direct current (DC) cooling fans, an air-conditioner mesh air filter, and an axial ventilation fan. It was found from the results that the hourly values of water production of MSAWG were proportional to the hourly rates of relative humidity, but they were inversely affected by the corresponding hourly values of the ambient temperature. Night-time and early morning were the most effective times to produce the highest amount of fresh water from Malaysia’s atmosphere using MSAWG, as the increase in the rates of relative humidity and the decrease in the values of ambient temperature occurred over these periods. Based on the varied hourly rates of relative humidity with the ranges between the minimum rate of 55% and maximum rate of 85%, an equation of Y = 0.2285X + 36.675 with R2 of 0.9404 was achieved from the 48 h experimental work to estimate the water production of MSAWG in Malaysia, where Y and X were indicated as the rate of relative humidity and the value of water production, respectively, in this equation. In conclusion, the MSAWG produced a consecutive cumulative water volume of 3.432 and 6.997 L experimentally in the periods of 24 and 48 h, respectively. The estimated cost per liter for MSAWG was USD 0.466. Some water quality parameters of the fresh water produced by MSAWG were analysed in the laboratory, which showed that they met the World Health Organization (WHO) drinking water standards. Therefore, MSAWG can be employed as a sustainable alternative to generate annual daily fresh water from Malaysia’s tropical atmosphere and aid in mitigating the problem of unpredicted water shortage in the country.
