The difficulty with parallel parking, especially when going backwards is when adjusting the steering wheel so that the car can park in the right direction. Based on these problems, this study aims to design an automatic parking system. To improve parking success, a trajectory tracking system with fuzzy logic control will be implemented on a 1/7.5 scale test car. The coordinates obtained from the bicycle kinematic model are compared with the design trajectory. The difference between the facing direction read by the gyroscope sensor and the trajectory design is processed using a fuzzy logic controller to direct the servo motor as the steering wheel. The test results obtained that the error value for the position and direction facing in the automatic parking test using fuzzy logic control is 1.25cm and 1.59°. Keywords: Trajectory tracking, gyroscope, fuzzy logic control, parallel parking

Switching substations are usually supplied from one express feeder which can cause a low level of reliability due to disruption or outage on the express feeder. Also, the lack of power supply at the ends of the network causes voltage drops. One way to solve this problem is to reconfigure the network. In this study, testing was carried out on a distribution system in the Nagan Raya Regency, namely the distribution system of PT. PLN (Persero) ULP Jeuram originally had a radial system. Furthermore, the distribution system was reconfigured with the Krueng Isep hydroelectric power plant which was included in the PLN ULP Jeuram grid so that the system that was originally radial became a loop configuration. The method used in analyzing the network reconfiguration process is to use the ETAP 12.6 application. As a result, after reconfiguring the network the voltage increased from 19.2 kV to 20.7 kV, the highest increase was at the Beutong Substation which reached 1.5 kV and decreased power losses in the network with a total of 188.2 kW and 263.1 kVAR. Furthermore, before the network reconfiguration, ULP Jeuram SAIFI value was 22.25 times/customers and SAIDI values 1337.74 minutes/ customers. However, after reconfiguring the network, ULP Jeuram SAIFI value fell to 15.39 times/customers and SAIDI to 945.6 minutes/customers, resulting in an increase in system reliability by 70.69%.

This paper analyzes the effect of the presence of foreign particles on an equilateral arrangement of 3 phase gas insulated switchgear (GIS) insulation equipment. In this calculation, the electric field characteristics will be analyzed in 3-phase equilateral GIS by varying the location of the particles in the GIS tank. Particles are modeled to have a length of 5 mm and a thickness of 0.5 mm located in a 3 phase GIS equilateral arrangement with a tank diameter of 150 mm and a conductor diameter of 25 mm. The electric field calculations are reviewed at several points in the 3-phase equilateral GIS tank. The simulation and calculation of the electric field were calculated with FEM method software. The results of the calculations show that there are differences in the characteristics of the electric field between normal GIS and GIS where foreign particles are present. The difference in these characteristics can be seen in the magnitude of the electric field, and the ratio of eccentricity from some point of view.

Gapless arester leakage current can be used as an indicator to determine the aging level of the arester. Leakage current is influenced by contaminants present in the arester insulation. This paper analyzes the effect of contamination on arester leakage currents as an indicator of arester aging. Contaminants used are calcium carbonate plus kaolin dissolved into water, to determine the level of calcium carbonate contaminants, the ESDD (Equivalent Salt Deposit Density) method is used. Contaminated aresters are measured as leakage currents flowing to the block elements and to the arester insulation. Based on experiments that have been carried out, the increase in leakage current of the arester on the block element that increases the leakage current to the level of light, medium and heavy contamination rises by an average of 17.5% for the voltage of all test voltages. While at low and moderate contamination the leakage current that occurs in the polymer arester insulation does not significantly change, the leakage current generated is linear with the level of contaminants in the arester body. It can clearly be concluded that the effect of contamination is very significant in changes in leakage currents.

This paper presents the results of an energy audit carried out to assess the potential of energy savings in educational institutions in Ghana using the Kwame Nkrumah University of Science and Technology (KNUST) as the case study institution. It also outlines a simple and effective technique for such an audit. The College of Engineering; one of the six Colleges of KNUST was used as the study location. Light bulbs and fans at the classrooms, corridors, laboratories and washrooms were monitored for energy wastage. The monitoring period was one month. The energy wastage over the period was estimated to be 1718.24kWh, which is high. The yearly energy wastage at KNUST for the areas assessed is projected to be 95.276MWh, which is alarming. Urgent steps are therefore needed to curb this wastage. Keywords : Energy auditing, Energy efficiency, Energy efficiency measures, Energy saving and Energy w astage

Signal in the form of voltage are often need to be transmitted when we deal with measurement. However, voltage signal transmission creates many problems. The series resistance that appears between the output of the signal conditioner and the load produces some voltage drop. Even a few millivolts of the voltage drops could significantly alter the percentage error of the measurement. Current signal is the same everywhere in a series loop. So, by converting the signal into a current and then sending the current signal will assures that the load will receive all of the signal we sent. In this paper, a simulation and an implementation of using instrumentation amplifiers and V-I converter for sending a voltage signal has been conducted. The process variable being measured is a differential pressure that is sensed by a pressure sensor. The output voltage signal was then amplified by an instrumentation amplifier and fed to a V-I converter for transmission purpose. The results is an increase in output current when the presssure was increased. It can be concluded that the instrumentation amplifier and V-I converter are the devices that are properly used for a voltage signal transmission. Keywords : Instrumentation amplifiers, signal transmission, V-I converter, voltage signal, current signal, pressure sensors.

Solar panels have constraints on output power that are not large enough and they are highly depend on natural conditions. Solar panel power depends on the intensity of sunlight received and the temperature of the surrounding environment. In order to get the maximum output power of the solar panel, an additional device called the solar tracker is needed. This research has contributed to increasing the output power of solar panels by directing solar panels perpendicular to sunlight. The use of this research is very useful in the application of the multi-axis tracker application from the sun. By knowing the rising angle of the sun every morning and the circulation angle to sunset, the tracker will work quickly so that the energy used for movement is very small. The reference angle generated by the ANFIS training algorithm is more accurate because the calculated data will be confirmed again by the sensor. And this system can work offline, without being connected to a data center, so it can be used in remote or isolated areas.

Penelitian ini memiliki kontribusi dalam meningkatkan daya keluaran panel surya dengan mengarahkan panel surya tegak lurus dengan cahaya matahari. Penggunaan penelitian ini sangat bermanfaat dalam penerapan aplikasi tracker multiaxis dari matahari. Dengan mengetahui sudut terbitnya matahari pada setiap pagi hari dan sudut edar sampai dengan terbenam, tracker akan bekerja dengan cepat sehingga energi yang digunakan untuk pergerakan sangat kecil.
