Abstract

Kawaluso Island is one of the outermost islands in Indonesia with a distance of 68 KM from the city of Tahuna or 5-10 hours by boat from the capital of the Sangihe Islands Regency, Tahuna. Currently, electricity on Kawaluso Island is supplied by a diesel power plant (PLTD) with a capacity of 200 kW. This condition causes Kawaluso Island to be electrified 12 hours per day. So that additional sources of power plant are needed so that the electricity on Kawaluso Island is on 24 hours a day. Therefore, a solar power plant (PLTS) is one of alternative as additional power for Kawaluso Island and reduces the cost of production. A diesel power plant where the price of industrial fuel reaches up to Rp. 24.500 and it make Cost of Energy Rp. 10.360/kWh. The method used in this study uses the Levelized Cost of Energy (LcoE) method.

Abstract

Electricity is a means to support community activities both in efforts to improve welfare and to encourage economic development. The National Electricity Company (PLN) as the state electricity provider has not been able to reach the electricity network in remote villages. Andungbiru Village, Tiris Subdistrict, Probolinggo Regency is one of the areas that install PLTMH (Micro Hydro Power Plants). Due to the increase in load every year, the current conditions of the PLTMH power grid in Andungbiru village experience a more even distribution of R, S, and T phases in units 1 and 2. This situation causes very large voltage drops and loss of power to the channel so it needs to be configured to reset it. Based on the results of network configuration, phase voltage R, S, and T in unit 1 is 7,9136% V, 5,9599% V, and 6,4707% V which was previously 22,3385% V, 18,0570% V, and 47,3622% V. The results of reconfiguring unit 2 networks for falling phase voltage R, S, and T are 2,6957% V, 1,4909% V, and 0,8985% V which were previously 7.3672% V, 17,2237% V, and 13,8929% V. The power loss in unit 1 after reconfiguring the network is 2873,3886 Watts which was previously 20910,9708 Watts and in unit 2 after reconfiguring the network is 221,0193 Watts which is 1749,6933 Watts. The results of network reconfiguration can reduce voltage drop and power loss in low-voltage networks and follow the standard that the maximum voltage drop is 10% of the nominal voltage of 220V.

Abstract

Today, there were many cases of theft or infringement of electricity in various ways. This was caused PLN to suffer losses due to the theft of electricity amounting to Rp 1.5 trillion per year. Electrical theft focused on kWh meter there were various kinds, such as by changing the side of the MCB and adding a needle on the kWh meter. The objective of this study were found out the recorded kWh ratio if the installation was installed normally with a modified installation by changing on the MCB side, adding a needle, and comparing the economic value that PLN should had obtained when the kWh meter was installed normally and the kWh meter was changed. The method used in the research for normal measurement as much as 6 times the rotation of the disk and used 5 variations of load ; the measurement by changing the MCB and adding the needle was the same as the normal measurement, only when changing the MCB changes 2 A to 4 A, and when adding the needle, the disk was plugged with a needle. The result showed that the average of error difference between kWh meter that was installed normally with that has been changed on the side of MCB is 0, and kWh meter installed with normal that has been changed add needle equal to -44.1586. The difference in total cost of electricity for one month for normal kWh meter with which has been changed on the MCB side was Rp. 165.914.-, and for the normal kWh meter difference with the added needle of Rp. 58.610.

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

In various industrial applications, the use of a power supply that uses a conventional diode single-phase rectifier topology results in high harmonic values in the electricity distribution system. One of the real impacts of this harmonic value is the heating of the electric power system equipment and power losses. High rms current values due to harmonics often cause problems in protection settings in addition to efficiency problems. The percentage value between the total harmonic component and the fundamental component is called THD (Total Harmonic Distortions). Therefore, in this study an asynchronous dcdc boost converter is connected to the output side of a singlephase diode rectifier which is capable of improving power factor and low harmonics. So that a THD value of less than 15%, PF (Power Factor) = 0.92-1 and a sinusoidal input current can be obtained. The implementation results show that the PFC (Power Factor Correction) method can work well on single-phase diode rectifiers.

Abstract

In today's aircraft industry, the flight control system and landing gear system cannot be separated from the role of the hydraulic technology system. As the prime mover of the hydraulic pump or actuator hydraulic system, a permanent magnet synchronous motor (PMSM) is used. This PMSM is a substitute for the role of conventional combustion engines, and PMSM is considered to have several advantages in increasing performance and efficiency. This research will develop a system to find parameter values for Linear Quadratic Gaussian (LQG) controllers in a hydraulic pump system that is installed as a load from PMSM and then observe and analyze the performance of the response of the synchronous motor system, namely in the form of changes in rotor rotation speed, torque electric power, and stator current on the q-axis. The results of the research on the characteristics of the PMSM implemented in the hydraulic pump system show that the LQG controller is more optimal when compared to the observer controller. The LQG controller is known to have a faster transient response, which is indicated by the value of the settling time improvement at no load, namely 116.67% for the observer controller and 364.705% without the controller. Then when the synchronous motor serves the nominal load, the rotational speed of the rotor produced in the steady state becomes 8.29% faster than the observer controller and 74.49% without the controller. This rotor's rotational speed affects the time the actuator needs to extend and retract motion.

Abstract

Abstract—Hydrometeorological disasters such as flooding in urban areas are a big problem that must be managed. Indonesia as part of the maritime continent, has high rainfall variability, both temporally and spatially. Unfortunately, the density of instruments for measuring rainfall is still low. To solve the problem, this research will try to utilize and modify Closed Circuit Television (CCTV) cameras which have a large number in terms of quantity as instruments for measuring rainfall. The purpose of this research is to obtain rainfall image information and data generated by CCTV cameras. The image data is converted to quantitative rainfall data. The method used is the K-NN algorithm and machine learning. The research location is located in a corner of the city of Bandung with a geographical position of 60 53”30.49'S and 107.035” 12.27' E. The results of this research show that the K-NN algorithm can be applied to estimate rainfall data from CCTV images with an accuracy of more than 98%. The level of accuracy generated between CCTV camera image data and AWS is 94%. The level of accuracy is high means that CCTV camera image data can represent or be converted into quantitative rainfall data.

Abstract

Wind Power Plant (PLTB) has received a lot of attention from the public, researchers, and the government because of its advantages and role in reducing the causes of environmental damage due to the generation of electrical energy. Unlike power plants that use primary energy from fossil fuels, PLTB uses wind kinetic energy to generate electricity. Many problems arise because the wind speed is always changing every time. The resulting output voltage instability in the generator can affect the electric power system where the output electricity of the generator is injected. This paper describes how to analyze the generator output voltage control at PLTB. The generator used is a type of induction generator with two inputs (Double-Fed Induction Generator, DFIG). while the method of analysis is carried out using the PSIM simulation tool from Powersim, Inc. Control is carried out both on the rotor side (Rotor Side Converter, RSC) and on the grid side (Grid Side Converter), with the aim of maintaining the output voltage injected into the power grid with a certain level of voltage oscillation. The control results show that the generator output voltage can be maintained as desired.

Abstract

Maintenance of machines is highly necessary to prolong the operational lifespan of induction motors. Prioritizing preventive measures is crucial in order to prevent more significant damage to the machinery. One of these measures includes detecting abnormalities, such as misalignment, in the motor shaft. This research is aimed to detect the misalignment of induction motor experimentally by varying the coupling between normal and parallel misalignment. The signal readings were analyzed in the frequency domain using Fast Fourier Transform (FFT). The results revealed that in the case of coupling misalignment, a peak appeared at f = 13.5 Hz, whereas in the parallel misalignment condition with a 1 cm misalignment, a peak was found at f+fr = 20 Hz. By utilizing the Convolutional Neural Network (CNN) system, normal and parallel conditions can be detected with an accuracy level of 87.5%.
