“…Constraints that often faced by fisherman is to keep freshness of fish. The decomposition rate of fish is strongly influenced by fishing techniques, handling techniques, and onboard storage [21,25,30,31] [1]. Marine products are easier to decompose than other high-protein products [1,3,12].…”

Indonesia's annual marine fish potential of 6.5 million tons is spread over the waters of Indonesia's Exclusive Economic Zone. The constraint of which are often faced by fishermen is the decay that occurs during the storage process in which the fish becomes less fresh when it comes to the fish auction. The decomposition rate of fish after fishing is strongly influenced by fishing techniques, handling techniques, and onboard storage. The cooling or freezing process is the best method chosen for handling the catched fish to maintain its quality and freshness. This study was conducted by modifying the insulation material of purse seine cargo hold using a coolbox made of insulated materials from coconut coir and Palm Fiber. The purpose of this study is to know the influence of coconut coir and Palm Fiber composite insulation to temperature and cooling time in which will be compared with styrofoam insulated coolbox. The study was conducted by testing some specimens which will be selected with the thermal conductivity and lowest density. The compositions which is chosen were coconut coir and Palm Fiber composite that is mixed with polyurethane glue 4:4:1 ratio, having a thermal conductivity of 0.4643 W/mK and a density of 0.18 g/cm 3. Coolbox's test using coconut coir and Palm Fiber composite insulation was done using a 400 gram fish as a cooling load and ice that had been destroyed weighing 2 kilograms as a cooling source. Coolbox with coconut coir and Palm Fiber composite insulation has the lowest fish temperature of 0.7 o C, while the coolbox with styrofoam insulation has the lowest fish temperature of 1.8 o C. In addition, coconut coir and Palm Fiber composite coolbox is able to keep temperature below 20 o C for 16,5 hours, while with the same treatment styrofoam insulated coolbox is only able to keep the temperature below 20 o C for 16 hours. So it can be concluded the use of coconut coir and Palm Fiber composite is effective as insulation material because it can offset the performance of the insulation styrofoam .

“…The placement of support should take account of the movement of the piping system to the loading profile that may occur under various conditions. Because of the importance of this Support role, it is necessary to have a good plan for designing pipe support designs to be able to withstand the stresses of various loads [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

in the process of distributing LPG to all regions in Indonesia, LPG stations have an important role. In operation, LPG stations may have hazards caused by environmental conditions such as pipe fatigue (fatigue) due to geotechnical forces or failure of components in the system. Research case of piping systems used pipe stress analysis. The purpose of this analysis is to know the deflection of the pipe, the loads that occur by the pipe, and the safety of the pipe and its support. This analysis refers to the code or standard ASME B31.3 where the stress analysis is performed using software. In the process of pipe modeling, there are variations of loading such as pressure load variation, wall thickness and elevation of soil degradation value. From the results of calculation and simulation pipe stress analysis using software can be seen that header pipe 12 inch at LPG station of Semarang is NOT stress, so it is safe to be use. The thickness of the pipe allowed for to be unstable when the operating pressure is greater than 0.15 inch, and the operating pressure allowed for the pipe to be unstable at a thickness of 0.4 pipe (schedule 40) is less than 725 Psi (50 Bars).

Enerji verimliliği günümüzde giderek önem kazanmaktadır. Enerji verimliliğinin arttırılması ile yakıt tüketimi ve çevreye zararlı olan etkileri azaltmak mümkün olmaktadır. Ayrıca yakıt fiyatlarının önümüzdeki yıllarda artan trend göstermesi öngörülmektedir. Gemilerde uygulanan enerji verimliliği uygulamalarında enerji kaybının yaklaşık %25'ini oluşturan eksoz gazından enerji kazanım yöntemleri öne çıkmaktadır. Gemilerde atık egzoz baca gazı enerjisini geri kazanmak için ekonomizör kullanılmaktadır. Bu çalışmanın amacı, ekonomizer ana kazanın ön ısıtıcısı olarak çalışırken, kızgın yağ sisteminin performans, maliyet ve çevresel etki analizlerini gerçekleştirmektir. Bu kapsamda ana makinesi 4350 kW, kazanı 1500 kW ve ekonomizeri 340 kW olan bir gemi ele alınmıştır. Sonuç olarak gemilerde ekonomizer gibi atık ısı dönüştürücülerinin kullanılması ile hem tasarruf sağlanmış hem de emisyonlarda azalmalar görülmüştür.
