Heat control on the engine generator with a fresh water cooling system serves to stability maintain of the temperature engine. The water cooling system to absorb heat from combustion process heat transfer analysis is carried out based on measurements and calculations to find out optimally the work of the generator engine. Experimental research methods are carried out by to many cooling water drums easly cooling water, and increasing volume of cooling water. Based on the results of experimental analysis and calculations that the standard cooling at 1500 rpm an average Q<sub>cooling</sub> = 79,979.23 Watt; and the percentage of heat absorption = 14.04%. Cooling with &nbsp;drum cooling at 1500 rpm an average Q<sub>cooling</sub> = 32,737.60 Watt; and the percentage of heat absorption = 41.44%.

Good handling of fish after the ship is taken is one way to get good results. Handling can be in the form of maintaining the temperature of the catch. Regarding to the results of the 2017 applied research carried out related to ships and fishing gear in the coastal Karawang district, it is denied that fisheries in this area are generally very low in terms of the production of fish caught which is poor quality provided direct impact on the sale price of the catch. Based on this, an easy cooling engine is needed that does not burden the operations. Therefore the purpose of this study is to make a solar powered refrigeration unit (solar energy), knowing the performance of a mini refrigeration unit that has been made (COP) and finds out the quality of fish stored in accordance with organoleptic observation. The results showed that the mini refrigeration units made worked well with performance (COP) of 3.51 mean mini refrigeration units that have a good efficiency above 1. Moreover, the fish quality was stored in the mini-refrigerators had organoleptic values ​​according to the standard food is an average of 8.</em></p> Rahmad Hadi, Apih Suparlin, Dian Sutono, Terry Yuliardi Copyright (c) 2019 Jurnal Airaha http://jurnalairaha.org/index.php/airaha/article/view/114 Fri, 30 Aug 2019 09:12:37 +0000 The Effort for Minimizing Exploitation Impact of Tiger Prawn (Penaeus monodon, Fabricus 1798) With Captured Size Determination in Tarakan Water, North Borneo http://jurnalairaha.org/index.php/airaha/article/view/113 <p><em>The Tiger prawn (Penaeus monodon, </em>Fabricus<em> 1798) was dominantly captured at Tarakan waters, North Borneo. The captured activity in this area was done annually and shown over the exploitation rate. Its need an effort to minimizing exploitation impact for sustainability management. Legal size determination is one effort for resources management. The aim of this paper was to the determination of legal size as an effort for sustainability management of tiger prawn at Tarakan Waters, North Borneo. Population parameters of tiger prawn were used in this paper from the article was published in 2013 and 2018. Tiger Prawn samples collected from fishermen captured was landed at Lingkas Ujung (2012) and Selimit Pantai (2016) landing site, Tarakan, North Borneo. Result of the research shown length at first captured (Lc) of tiger prawn is 33.6 mm and smaller than a length at first mature (Lm) is 40.7 mm. The tiger prawn size (Lc_opt) for exploitation 47-50 mm. it was bigger than Lm and give optimal economic value.</em></p> Andri Warsa, Amran Ronny Syam, Duranta Diandria Kembaren Copyright (c) 2019 Jurnal Airaha http://jurnalairaha.org/index.php/airaha/article/view/113 Tue, 03 Sep 2019 08:35:51 +0000 Fish Aggregation Devices (FAD) Distribution at the Purse Seine Fishing Ground in the Indian Ocean http://jurnalairaha.org/index.php/airaha/article/view/115 <p><em>The Fish Aggregating Devices (FADs) have been utilized for a long time by the purse seine fishermen in Sibolga. This research was aimed at mapping the devices operating by the Sibolga fishermen in the Indian Ocean and identifying the dominant captured fish surrounding the set devices. It was carried out in the Nusantara Fishing Port of Sibolga, North Sumatera Province – Indonesia. The results of this research demonstrate that the FADs are set in three fishing grounds in the Indian Ocean of Indonesia namely (1) the waters surrounding Nias Island, (2) Exclusive Economic Zone of Indonesia, and (3) the waters surrounding Mentawai Island. Further, based on the species, the capturedfish dominantly in the surrounding set FADs are skipjack tuna (1,114.196 tons), short pectoral Mackerel (</em><em>338.344 </em><em>ton</em><em>s), shortfin scad Mackerel (217.505</em><em> ton</em><em>s), Mackerel Tuna (165.67 tons), Sardine (148.786 tons), and Yellowfin Tuna (78.175 tons). Overall, this research infers that the captured fishusing purse seine fishing gear are dominantly represented by the small and medium sizes. Moreover, the potential fishing grounds for Sibolga fishermen are located in the surrounding waters of Nias Island and Mentawai Island. </em></p> Deni Sarianto, Djunaidi, Kadi Istrianto Copyright (c) 2019 Jurnal Airaha http://jurnalairaha.org/index.php/airaha/article/view/115 Mon, 09 Sep 2019 12:59:17 +0000 The Suitability of Fish Handling on Pole and Line http://jurnalairaha.org/index.php/airaha/article/view/111 <p><em>Fish is a important sea catch, in addition to being the main source of protein, it is also the main livelihood for the fishermen.

The components of fish waste consist of the head, tail-bones, skin, and stomach contents that can be used as fish oil. The one of the problem in the use fish oil as a raw material for intermediate products is the difficulty in making a comparison ratio between fish oil and other ingredients, so we need to know the composition of fatty acids as a reference formulation for the application of waste utilization of tilapia oil. The method used is a quantitative method that is identifying fatty acids in tilapia oil. Data analysis uses Gas Chromatography (GC) as chromatogram data. Based on the results of the analysis that the composition of fatty acids from waste tilapia oil as follows: the dominant saturated fatty acids are palmitic fatty acids as much as 20.96%, the dominant monounsaturated fatty acids are oleic fatty acids as much as 22.63%, and fatty acids the dominant polyunsaturated fatty acid is linoleic as much as 16.77%.
