Abstract

Quality of fish is an important factor and determines the high selling price of fish in the market. In achieving that it will require proper handling in the process of cooling the fish before it is sold. To keep the freshness of the fish, fishermen usually use Styrofoam-based coolbox as its isolation. In this study modify coolbox using rice husk which serve as insulation on coolbox. This study aims to determine the effect of insulation using rice husk over time and temperature which will be compared with Styrofoam coolbox. Before the experiment, the first thing to do is to test the composition of rice husk with white cement. Where is the best composition to be used as insulation on coolbox. The tests are thermal conductivity, density, and flexural strength tests. From the test results obtained the best composition of rice husk and white cement is 1: 1 which has a thermal conductivity (0.746 W / mK) and density (0.32 gr / cm3) better than other compositions. In the experiments performed using 3 kg of wet ice it was found that in 24 hours cooling time, the rice husk coolbox had the lowest temperature of 13.5 ° C and the lowest Styrofoam coolbox temperature was 10.6 ° C.

Abstract

Basically a ship has a variety of conditions, namely cargo handling, anchoring, maneuvering, and sailing its requires large electricity consumption. The quality of the voltage is not good will cause damage to electrical equipment on board. Disturbances that occur in electrical system of MT. X may result in a decrease in the performance of existing electrical equipment on the vessel and affect a certain condition as in loading-unloading conditions the time required for loading and unloading becomes longer due to interference with the electrical system. The MT.X tanker system has 5 (five) main busbars: BUS 1, FEEDER PANEL, DSB 2, DSB 3 & 4, and DSB 6. The MT tanker. X has a generator of 3 units with a power of 680 kw each, a frequency of 60 hz and a voltage of 450 V. Transient disturbance analysis under loading-unloading condition occurs transient response due to starting ballast pump where the voltage rises and then drops within 0.5 seconds with the highest value of 100.44% at 4.01 seconds and the lowest value is 99.50% to 4.81 can then reach steady state conditions at 99.9%, which does not exceed the IEEE standard limits. In harmonic disturbances under loading-unloading conditions, in the feeder panel connecting the harmonic source with load at the 5th order, the value of VIHD is 8.77%, which exceeds the IEEE standard of 5%. While the value of VTHD in loading and unloading conditions also exceeded the predefined standard limits. After installation of the filter, it can be seen that the value of VIHD at the 5th order in loading-unloading condition decreased to 3.6% after the installation of filter on feeder panel, or equal to decrease as much as 5.17%. The decline in the value of VIHD has fulfilled the IEEE 519-2014 standard of 5% on each individual order. Meanwhile, VTHD value in loading-unloading condition also decreased, from 11.18% to 7.02%.

Abstract

Decreasing in fossil energy reserves about 3% every year and has not been matched by the discovery of new energy reserves. Therefore, it is necessary to increase the use of renewable Energy to meet energy needs. Renewable energy is energy derived from sustainable natural processes. Indonesia located in the tropical area, it has a lot of potential ocean energy. OTEC (Ocean Thermal Energy Conversion) is one of many renewable energy sources from the ocean. OTEC or Ocean Thermal Energy Conversion is one of the latest technologies that used the temperature difference between deep and shallow seawater. OTEC system generally used ammonia (NH3) as working fluid. Ammonia is used because it has a relatively low boiling point compared to water. OTEC system consists of evaporators, turbines, generators, condensers, and pumps. In this research, the authors focused on the design of lab-scale OTEC turbines. 2 stage turbine will be varied the tilt which is 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 degree. The computational fluid dynamics (CFD) method is used in this research to simulate the OTEC Turbine. Based on the simulation results, the highest efficiency and net power is a 2 stage 40 degree turbine with 57.45% of efficiency and 287.25 kW of generated power

Abstract

Pressure relief device serves to control and limit the pressure by directing the flow into an additional path. In the process of purification of oil and gas, application of PRD are found in production gas separator system. However, based on API 581, the PRD also has a risk of failure that every oil and gas company needs to conduct regular inspections to ensure the reliability of PRD. One approach to evaluating critically the PRDs for arranging and scheduling programs is to use the risk-based inspection (RBI) method. The RBI is a systematic approach to the method of inspection management of equipment or works unit based on the level of risk that the equipment or work units. Risk assessment for production gas separator system’s PRD has based on API RP 581 third edition.  After knowing the level of risk for PRD, the risk needs to be evaluated. For acceptable risk, it can be used as a reference to determine the next inspection until risk target. Meanwhile, unacceptable risk should be inspected immediately after RBI analysis.

Abstract

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/cm3. 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 0.7oC, while the coolbox with styrofoam  insulation has the lowest fish temperature of 1.8oC. In addition, coconut coir and Palm Fiber composite coolbox is able to keep temperature below 20oC for 16,5 hours, while with the same treatment styrofoam  insulated coolbox is only able to keep the temperature below 20oC 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.
