Abstract

Indonesian geographical position that located at equator line and sunrays along the year, then it is appropriate to implement and use sun energies that are abundant in amount and inexhaustible. Based on that matter, then to fulfill electric needs in Indonesia and as alternative of PLN power supply, then it is appropriate for development of Photovoltaic, a process can convert sunrays into electric energy directly with aid of solar cell. The use of photovoltaic by using sun energies located in VEDC Malang as garden power supply is one example of applicative project of electric power potential development by using sun energies widely in Indonesia. From experiment and analysis, obtained break down voltage percentage with same load in photovoltaic system, the highest occurs in cloudy weather 4.76% and the lowest occurs in bright weather 4.17%. From technical standpoint, it seen that used sun module and battery are not efficient compared with existing load in VEDC Malang and from economic standpoint, cost per kWH of the system Rp 42.400,- an while from PLN electricity that is Rp 27.969,5,-. Finally, it can be concluded that the use of Photovoltaic system in VEDC Malang is not efficient yet and expensiveKeywords : Photovoltaic, effeciency, breakdown voltage

Abstract

Penelitian ini membahas tentang perbandingan keluaran daya antara panel surya konvensional dengan panel surya yang menggunakan sistem  pelacak sinar matahari (solar tracker system). Pada penelitian ini juga membahas bagaimana rancangan sistem fotovoltaik yang akan digunakan untuk mencatu lampu penerangan jalan umum dengan menggunakan lampu LED DC sebesar 5 watt dan rancangan sistem alat pelacak sinar matahari yang berbasis Arduino uno. Perbandingan yang dilakukan adalah dengan mengukur arus dan tegangan keluaran kedua buah panel surya dimana satu panel surya konvensional dan satu panel surya menggunakan sistem pelacak sinar matahari. Pengujian dilakukan dalam dua kondisi yaitu pada kondisi cuaca cerah dan pada kondisi cuaca mendung. Pada cuaca cerah rata- rata selisih efisiensi antara panel surya yang menggunakan sistem pelacak sinar matahari dengan panel surya konvensional adalah sebesar 1,12% dan pada kondisi cuaca mendung adalah sebesar 1,94%. Hasil pengujian menunjukkan bahwa panel surya yang menggunakan sistem pelacak sinar matahari memiliki tingkat efisiensi daya yang lebih tinggi dari pada panel surya konvensional.

Abstract

The movement to reduce emissions can be done by developing renewable energy and electric vehicles derived from renewable fuels. This electric vehicle will use batteries and motors so that BLDC motor was chosen in this study. BLDC motors use electronic commutation so a controller is needed. The controller used is a PI controller assisted by the hysteresis current controller. The output of the hysteresis current controller needs to be converted to a DC voltage using a DC-DC converter. One of the DC-DC converters is a zeta converter which can increase or decrease the voltage so that it can be used when the load voltage varies as will be used in this study. The results showed that the BLDC motor connected to the zeta converter with the controller can be used when the load torque varies. If the applied varying load torque does not exceed the rated torque, the actual speed will return to the reference speed without exceeding a 10% error. On the other hand, the actual speed will return to the reference speed by exceeding the 10% error, if the applied varying load torque exceeds the rated torque.

Abstract

After years of operation, the plant will no longer operate optimally according to its design. The practice of the work cycle shows that the original value of thermal efficiency will always be below 100%, this is because during the cycle process of creating work, the energy received by the system by heat transfer will not be fully received and will be absorbed by the environment. In this research, thermal efficiency analysis was carried out in accordance with the first and second laws of thermodynamic efficiency and thermoeconomic calculations to calculate losses. Based on calculations that have been carried out, the thermal efficiency of the Star Energy Geothermal Darajat unit-3 geothermal power plant system is 21.72% with the largest exergy loss being in the condenser component of 62,219,418 kW with an exergy loss cost of 252,766,682.24 Rp/ days and the smallest is in the cooling tower of 599,362 kW with exergy loss costs of 23,655,907.11. Rp/day from the following results it can be seen that this efficiency value depends on the performance of each component.

Abstract

The development of EBT in Indonesia is still far from the target of the National Energy Policy (KEN), the EBT mix of 23% in 2025 and 31% in 2050. One form of EBT development is utilizing solar energy in building technology that has high energy efficiency so that the number of electrical energy consumption is close to zero or called nearly Zero Energy Building (nZEB). Therefore, it is necessary to design the most optimal rooftop solar power plant (PLTS) so that it has good energy production and economic feasibility. To get a good energy production, simulation is carried out using HelioScope software by inputting data on the mechanical and electrical segments so that the amount of energy that can be produced by the rooftop solar power plant is obtained in detail. The results of the simulation of the rooftop solar power plant system that is installed on-grid in HelioScope are composed of 96 monocrystalline solar panels of Trina Solar TSM-DE20-605W (605W) and 3 3-phase inverters of Growatt MID 17KTL-X. The rooftop solar power plant produces an annual production of 84,08 MWh with a performance ratio of 82,1%. Thus, the average percentage of energy supply from rooftop solar power plants is 39,82% or can be said to be good in supplying the electrical energy needs of buildings so that the nZEB can be developed. From the simulation results, the economic feasibility is known, with the Break Even Point (BEP) reached in 12,4 years of the 25 years project period, and the Net Present Value (NPV) and Return on Investment (RoI) are positive, indicating that the rooftop solar power plant is profitable and feasible to develop.
