Abstract

Livestock vessels are used to distribute and transport livestock from one place to another. Similar research has been carried out by making cattle models in the beams which are considered to make air distribution less evenly. This research will be carried out simulation use 3D cattle’s model. This simulation aims to determine the distribution of air temperature, air velocity, air pressure and air flow patterns uses a CFD (computational fluid dynamic) simulation method. Based on the simulation result, the average of air temperature distribution is 300oK or 27oC at cattle pen A and B. The average of air velocity distribution is 0,669 m/s at cattle pen A and 0,7 m/s at cattle pen B. The average of air pressure distribution is 0,211 pa at cattle pen A and -0,267 pa at cattle pen B and the airflow pattern is around a model of cattle. The distribution of air temperature at 300oK or 27oC by RH (relative humidity) 70%-90%, THI (Temperature Humidity Index) shows in the alert condition between 75 – 78. So, The cattle pen A and B have not good the comfort zone and make a cattle to be mild stress. Because of it, the air temperature has to be down by adding a cooling instrument.

Abstract

Gas and steam power plant (PLTGU) is a combined cycle between PLTG and PLTU. The parameters to be achieved in order for the PLTG system to work optimally are regulated in ISO 39772. The gas turbine can work optimally if the air temperature enters the compressor 15ᵒC, at 60% moisture and at a pressure of 101.3 kPa. But data from BMKG condition of environment in Gresik mean at temperature 32ᵒC at relative humidity 65% to 85%. Therefore a cooling system is required to cool the inlet air gas turbine. On the other hand the exhaust gas temperature from HRSG still high and can be utilized as the energy source of the absorption cooling system. From the results of balanced energy calculations obtained some results such as the amount of exhaust gases from HRSG of 52952 kW and the power required to cool the inlet air of 22365.65 kW. The result of exergy calculation obtained some results the biggest destroyed of energy in combustor amount of 287369 kW. Five absorption cooling machine LG type WC2N135 is arranged in parallel to achieved the power. When the turbine inlet temperature is 32°C the power is 125251,127 kW otherwise turbin inlet temperature is 15ᵒC the power is 139986,53 kW.

Abstract

In the process of loading and unloading low calorie coal / LRC (Low Range Calorie) there is often pollution of coal dust and self combustion. This is because of the character of LRC coal is easily destroyed, the dust is very light and easy to burn. To prevent the occurrence of fire hazard, it is attempted to break one of the danger chain by optimizing the dust collector. Therefore, the capability of suction dust collector should be increased so that the impact of dust can be reduced. The simulation shows that the dust inside the conveyor can not be inhaled because the velocity of the inlet conveyor is 2.9 m/s. While the suction collector force of 1.5 m/s causes the dust collector not to capture the dust completely. Therefore it is necessary to increase the velocity of the suction channel on the dust collector, by varying with ratios 3 and 4. Between the two variations the best suction is the ratio 3 with the suction rate of 9 m/s. Furthermore, there is a change in suction hood angle with angle variation of 14 degree, 17 degree, 20 degree to get mass concentration. All angle variation within suction speed 12 m/s. The simulation result with an angle of 14 degrees obtained mass concentration of 14940,23 mg/m,3 with an angle of 17 degrees of 3,05 mg/m3, and with an angle of 20 degrees of 0,000741 mg/m3. Of the three variations, the mass concentration obtained at the outlet is at least 20 degrees suction hood angle.

Abstract

Previous research was the beginning of the manufacture a multifunctional freezer, a machine that has two functions for cooling and drying and is aimed at preserving fish both dried and cooled. The evaporator on the machine is used for cooling the fish in the refrigerator. The cooling process has a weakness in the cooling system where the temperature in the chamber can’t reach a temperature below 0°C when the load is given above 0,5kg, and its cooling rate is less efficient so that the process of temperature reduction in a chamber given the load variation has a long enough time, so it can be concluded that the performance of the chiller is less optimal. In this final project, a cooling system redesign is carried out on a multifunctional freezer machine, as well as a capillary tube with a diameter of 0,31 inches and a length of 1,5 meters. Test results were obtained with weight variations of 0,5kg, 2kg, and 3kg. Average cooling speed of 0,255 kJ/s, chill room temperature of 2,7°C to -6°C, and the best coefficient of performance are obtained from the test results at a weight of 3kg with a COP value of 6,609 at 30 minutes and 5,133 at a test time of 60 minutes or 1 hour of operation of the multifunction freezer.

Abstract

In previous studies, a Multifunction Freezer machine was made, which is a tool similar to a refrigerator in general, namely to cool food ingredients, but the advantages of this Multifunction Freezer Machine are made so that it can have 2 uses, namely, to cool and dry food ingredients such as fish etc. The weakness of the drying system in the previous multifunctional freezer machine was in the wrong placement of the fan and condenser which resulted in a less than optimal reduction of the water content in the ingredients (fish) for processing salted fish. The method used is to redesign or redesign the placement of the fan and condenser so that the drying system can work optimally and can reduce the water content of the ingredients (fish) as needed for salted fish processing. This research is to redesign the Multifunctional Freezer machine which was previously made by placing the fan and condenser on the left side of the drying chamber and by adding a glass heater after the condenser and the results obtained are room temperature 48.7 oC and fish temperature 34.2 oC, moisture content 6.583%, drying rate 0.378 gram/minute and performance factor 3.74 within 180 minutes or 3 working hours of a Multifunctional Freezer Machine.

Abstract

There is a case on KM Spil Rumi in the form of Lubrcating Oil (L.O.) cooler damaged due to leakage. The existence of this case is the basis of this research to find an alternative replacement with a redesign. The methodology used in this research uses LMTD (Log Mean Temperature Different). Based on the calculation results, it is found that the shell and tube heat exchanger has a better overall convection coefficient value with a value of 538.98 W/m2.C compared to the plate heat exchanger with a value of 459.19 W/m2.C. Although the overall convection coefficient value of the shell and tube heat exchanger is greater, the shell and tube heat exchanger has an overdesign value that is too large at 74.42%. Therefore, the plate heat exchanger with an overdesign value of 31.39% has a higher effectiveness value with a value of 64.3% compared to the shell and tube heat exchanger with a value of 46.4%.

Abstract

- Wind speed is the movement of air from areas of high pressure to areas of lowpressure. As the use of electric energy increases due to the growing human population in aregion, there is a need for renewable energy sources to convert renewable energy intoelectricity. Wind energy is highly potential if utilized, considering its relatively low utilizationfor electricity generation in Indonesia. In the initial stage of using wind energy for electricitygeneration, data on the wind potential of a region is required, thus an analysis of wind speedin several areas on Java Island is necessary. The wind speed data in this Final Projectincludes several regions in the Java Province, namely: Bandung, Banyuwangi, Bekasi,Gresik, Kudus, Malang, Semarang, Surabaya, Surakarta, and Tuban. The method used inmodeling wind speed involves the Weibull distribution, Rayleigh distribution, and Gammadistribution. Goodness-of-fit tests are applied to examine the best probability functions ofeach distribution to be analyzed. The distribution that meets the criteria of Coefficient ofDetermination, Chi-Square, and Root Mean Square Error is the Weibull distribution, asevidenced by the probability plots of the Weibull distribution, which closely match the actualdata from various regions. Areas with potential for wind energy to be converted intoelectricity are evaluated based on the percentage of wind speeds exceeding 2 m/s. The areaswith the highest potential are Tuban with a percentage of 56.89%, Malang with 56.71%, andBandung with 50.20%.
