Analysis of The Impact of Using Bentonite Cement on Rod Electrodes to Reduce Resistance Value
No full textOne of the factors that must be considered is the operational reliability of the electrical system and the safety of living things around it, namely the grounding system for the electrical source, which is commonly known as the grounding system and earthing system. Both are interconnected systems, whose function is to transmit excess current or voltage which generally causes damage to electrical equipment and endangers the safety of living creatures in the surrounding area. The best ground resistance according to the PUIL 2007 standard is < 5 ohms for the grounding system and < 3 ohms for the grounding system for the electronic device frame. The value of soil resistance is influenced by several factors, including soil resistivity, soil moisture, soil mineral content and soil temperature. In this research, the soil media will be replaced with Bentonite Cement, each bentonite cement media having a diameter of 10 cm, 15 cm, 20 cm and 25 cm. Measurements were carried out using a single rod electrode using the three-point method. In this research, the results were obtained, namely measuring the best measured resistance of bentonite cement with a diameter of 25 cm with a humidity of 90% in the morning, afternoon and evening on the 3rd day with a value of 13.38 Ω compared to the original soil medium with a humidity of 50% of 19 .24Ω. Next, comparing the diameter variations of 10 cm, 15 cm, 20 cm and 25 cm, the measured resistance values were 18.53 Ω, 16.63 Ω and 14.53 Ω. Meanwhile, the comparison of the percentage reduction in the calculated resistivity during the day on the 3rd day was 30.54% compared to the resistivity of variations in diameters of 10 cm, 15 cm, and 20 cm, only 3.78%, 13.64%, 24.56 %.81 PagesSkripsi Sarjan

Comparative Design Analysis of Variations in Number of Blades 3 and 6 on the Performance of Horizontal Wind Turbines with AC Generators
No full textWind originates from moving air, and it blows due to differences in temperature and pressure. The wind moves from high-pressure areas to low-pressure areas due to changes in atmospheric temperature and pressure. Wind turbines harness the energy of the blowing wind, impacting the turbine blades, causing the rotor to spin. The rotation of the rotor is connected to a generator, resulting in the rotation of the generator rotor and the generation of electricity. Therefore, wind speed influences the rotation of the rotor and the blades of the turbine. This thesis aims to make a comparison of the optimal effects of 3 and 6 blades on horizontal wind turbines. In this final project, the design involves a horizontal wind turbine with an AC generator rectified by a diode rectifier circuit. The blade design includes a blade length of 57 cm, a bottom width of 10 cm, and a tip width of 5 cm. Wind at speeds of 3 m/s, 3.5 m/s, 4 m/s, 4.5 m/s, and 5 m/s is applied to the horizontal wind turbine generated by a wind generator in the Lab. Terpadu. Results from the research include findings during battery charging, DC load, and AC load tests. In battery charging tests, using a 3-blade wind turbine, the highest voltage obtained is 31.31 volts with a produced current of 0.15 amperes. Meanwhile, with a 6-blade wind turbine the highest voltage is 33.31 volts, producing 0.15 amperes. When subjected to a DC load. the highest voltage using a 3-blade turbine is 32.96 volts, with a current of 0.18 amperes. In comparison, the 6-blade turbine reaches a voltage of 39.23 volts, producing a current of 0.18 amperes. Under AC load, the highest voltage using a 3-blade turbine is 23.27 volts with a current of 0.18 amperes. Using a 6-blade turbine, the highest voltage is 30.93 volts, producing a current of 0.17 amperes. The experiments were conducted at a wind speed of 5 m/s. The generated electrical energy is stored in a 12-volt. 6 Ah battery to power DC lamps and an inverter for AC loads.102 PagesSkripsi Sarjan
Design and Comparative Analysis of the Efficiency of Savonius and H-Darrieus Rotor Type Wind Turbines
No full textWind energy is one of the potential renewable energy sources to reduce
dependence on fossil fuels, but choosing the right type of wind turbine is still a
challenge to optimize energy conversion. This study compares the efficiency of
Savonius and H-Darrieus rotor type wind turbines under different wind speed
conditions to determine the best performance in each scenario. The research was
conducted using the experimental method through design, testing, and data
analysis with wind speed variations from 2 m/s to 6 m/s. The test results show that
at low wind speeds (2-3 m/s), the Savonius turbine is more efficient with an
output voltage of 3.6 V at 2 m/s and 8.6 V at 3 m/s, while the H-Darrieus turbine
only produces output voltages of 3.5 V and 5 V at the same speed. However, at
higher wind speeds (5-6 m/s), the H-Darrieus turbine showed performance with an
efficiency of 2.7% and a maximum torque of 88.17 Nm compared to the Savonius
turbine achieved an efficiency of 0.98% and a torque of 18.9 Nm. The Savonius
turbine is more suitable for low wind conditions, while the H-Darrieus turbine is
more optimal for high wind speeds, so its selection must be adjusted to the
environmental conditions.57 PagesSkripsi Sarjan
