Abstract

transportation is one segment that produced greenhouse gasses. Transportation produced 14% emission in the world and will continuously arise. Because of that, so many effort made to reduce the rises. One of them is to reduce fuel consumption. To reduced fuel consumption we need to reduced the drag aerodynamic effect. This experiment use ansys software modeling with reversed ahmed body car model. Simulation does at 30 km/h, 60 km/h and 100 km/h. from the simulation we can get the stream turbulency and the drag coefficient at 0.073.

Abstract

LRT Jakarta is one of the train operators in Indonesia. Apart from the passenger train (LRV), the Jakarta LRT also has a helper train (MRV). At the Jakarta LRT, the MRV operation has to pass a very steep incline, namely a 40o/oo gradient. This can result in a high probability of slippage. Such an incident can be avoided if we know how much the adhesion pull of the tow cart and the total resistance of the tow cart. For that we need further calculations regarding the total resistance of the train to the adhesion tensile force. So that in this final project will produce the maximum number of trains that can be pulled by the locomotive so that no slip occurs. With quantitative methods, data collection and calculation / analysis, the expected results are obtained in this final report. So that it can be seen that the maximum MRV traction effort is 107 kN and the resistance by pulling 3 LRV is 99 kN. Slip occurs when the resistance exceeds maximum traction effort. So it can be concluded that the MRV can attract 3 LRV without any slip when on the 40o/oo gradient path.

Abstract

When the Covid-19 pandemic occured, most of the industries and public facilities were not used properly, but the cooling machines was still used, resulting in large consumption of power and electrical energy. Along with high energy consumption where the availability of energy is running low, savings are needed. As an alternative so that the cooling machine can save energy is to use the subcooling method, namely the addition of a liquid suction heat exchanger on a spiral portable chiller with 29 spirals. Furthermore, the refrigerant used in the portable chiller is R407c. This study aims to determine the effect and effectiveness of Liquid Suction Heat Exchanger on a portable chiller. The results obtained are the coefficient of performance on the non-Liquid Suction Heat Exchanger portable chiller is 4,699 with a cooling capacity of 6,668 kW and compressor performance of 1,419 kW while the portable chiller with the addition of Liquid Suction Heat Exchanger, the Coefficient Of Performance obtained is 5,197 with a cooling capacity of 6,719 kW and compressor performance of 1,219 kW. From the calculation above, the use of a liquid suction heat exchanger in a portable chiller can increase the cooling capacity by 1,97 %.

Abstract

Energi surya merupakan energi yang dapat dikonversi menjadi energi listrik. Pembangkit listrik yang memanfaatkan energi surya sebagai sumber penghasil listrik adalah Pembangkit Listrik Tenaga Surya (PLTS). Dimana alat utama untuk menangkap, mengubah, dan menghasilkan listrik adalah photovoltaic. Penelitian ini bertujuan untuk merancang dan studi kinerja sistem PLTS untuk diaplikasikan pada egg incubator kapasitas 960 telur unggas yang sudah diproduksi sebelumnya. Pada penelitian ini, perencanaan meliputi perhitungan komponen-komponen utama sistem PLTS. Komponen utama yang paling penting, photovoltaic digunakan jenis polikristal. Selanjutnya pengambilan data dilakukan di linkungan perumahan dengan menempatkan photovoltaic di atap rumah. Tegangan listrik yang dihasilkan bisa dibaca pada charge controller sedangkan hambatan listrik diukur menggunakan digital multimeter. Dari hasil penelitian, didapatkan hasil bahwa dengan daya yang dibutuhkan untuk mengoperasikan egg Incubator 2834 watt jam perhari , maka sistem membutuhkan 6 photovoltaic ukuran 100 WP. Kemudian baterai 12V-100 AH, dibutuhkan sebanyak 14 buah. Adapun charge controller dibutuhkan minimal 36 A, sedangkan inverter dibutuhkan daya minimal 200 watt. Pada analisa kinerja panel surya, daya maksimal terjadi pada jam 10 am. Pada jam ini 98,0 W dicapai pada kondisi cuaca cerah berawan. Disusul 95,22 W pada cuaca berawan, sedangkan cuaca cerah menghasilkan daya terendah 93,85 W. Adapun pada jam 16 pm, terjadi penurunan daya pada ketiga kondisi cuaca. Seperti pada jam 10 WIB, cuaca cerah menghasilkan daya terendah, yaitu 92,48 W. Namun demikian, dari hasil ini terlihat bahwa kinerja panel surya tidak menunjukkan penurunan kinerja secara sigifikan pada sepanjang hari untuk ketiga kondisi cuaca : cerah, cerah berawan dan berawan.

Abstract

Refrigeration machines and air conditioning machines are an inseparable part of human life in improving the quality of activities. using air conditioning(Air Conditioning). Refrigeration systems in large buildings or those used to cool production machines in the industrial world require energy efficiency. This study uses the CLTD methodCooling Load Temperatur Difference Calculation of heat from each internal and external load of the room refers to the standard ASHRAE Cooling Load Calculation. With the calculation of heat on walls, roofs and floors, it is included in the calculation of external heat loads and the heat of occupants, equipment and lighting is included in internal heat and heat from infiltration and ventilation. Some of the parameter factors considered include heat from building walls, building roofs, building floors, heat in humans working inside, lighting used, production parameters and infiltration factors, ventilation. The value of COcontractualfor chiller 1 it was 6.47 and for chiller 2 it was 8.07. While the value of COPrefrigran is 7.8 for chiller 1 and chiller 2 which is 9.7. The efficiency obtained from these two units is chiller 1 57.4% and chiller 2 58.8%. From the calculation of the cooling load carried out, it is obtained 275576 ??BTU/hr or 330691 BTH/hr after adding 20% ??so that the engine is not burdened, if it is known that 1 kW = 3410 BTU/hr then the cooling load is 97kW.
