This study is a continuation of previous research, which only addressed the influence of a single capacitor on a three-phase induction motor in a single-phase power system, without further exploration of the extent of harmonic impact on the motor. The induction motor operates based on the principle of magnetic induction. This investigation employs a single-phase induction motor with lower power capacity compared to a three-phase induction motor. Three-phase induction motors have a small starting torque, preventing them from starting under full load. The study involves increasing the starting torque of the three-phase induction motor and operating it in a single-phase electrical power system using capacitors to improve power factor during the starting process while analyzing its harmonic effects. The research findings indicate that as the load on the motor increases, both the motor speed and harmonic current values decrease. This is evident when there is no load, and the motor speed is 1475 rpm; adding a load does not exceed this speed. The motor speed decreases as the load increases, while the presence of harmonic current values is due to the linear load, such as incandescent light bulbs. The study is conducted by enhancing the starting torque of the three-phase induction motor, imposing a significant load. The motor demonstrates more optimal and stable performance with the new method compared to the old method. Additionally, the harmonic current values with the new method are lower than those with the old method.","PeriodicalId":182397,"journal":{"name":"Elektron : Jurnal Ilmiah","volume":"48 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140513404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, the author tried to create and analyze a defect checking tool on PCBs to replace human vision to make it easier and can save costs. This tool is equipped with the help of a Logitech c920 Webcam and a Raspberry Pi 3b+ microprocessor which is used to store and run programs that have been created on Python programming software, so this tool can be used portablely. With these two technologies, Image Processing can be used to detect objects with the OpenCv library and Google Colab. PCB defect detection tool with the help of Image Processing uses yolo convolutional neural network method to help determine path damage on the PCB. You Only Look Once (YOLO) algorithm with five detection classifications, namely short, open circuit, missing hole, mouse bite, and spur. From the results of the study, the results were obtained that the YOLO algorithm was able to detect these five classifications with a value of mAP@0.5 short 90.67%, open circuit 97.86%, Mouse Bite 94.43%, Missing Hole 96.09%, and spur 97.56%.","PeriodicalId":182397,"journal":{"name":"Elektron : Jurnal Ilmiah","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125216501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When there is not enough parking space for the quantity of vehicles arriving, issues occur. Consequently, the atmosphere was no longer favorable due to the pandemonium of vehicles that had taken over. This research's objective is to create a working prototype of an vehicles parking system that can control the flow of vehicles into the campus area. This system's controller is a Wemos D1 Mini, which may be used with the ESP 8266 module to connect to the internet, RFID card for students' identities for drivers of motor vehicles, servo motors to control gateways, infrared proximity sensors to count the number of vehicless entering and exiting the parking area, and Google Firebase for student lecture scheduling databases are all examples of technology used in parking area today. The test results reveal that the system can successfully verify the schedule saved in Firebase and read the student's identity contained on the RFID card. Only students with class schedules on that day are permitted access to the parking area.","PeriodicalId":182397,"journal":{"name":"Elektron : Jurnal Ilmiah","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122641497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

WLAN is suitable for those who need internet. By using WLAN will be found various advantages for its users. Likewise with WiMAX (Worldwide Interoperability for Microwave Access) wireless technology, WiMAX basically has a function similar to WLAN, but with certain small differences. WLAN can cover one local area, in contrast to WiMAX which can cover a metropolitan area of up to 50km. Antenna is an integral part of WLAN and WiMAX. This paper discusses a three-band microstrip antenna optimized for WLAN and WIMAX technology. The antenna consists of two layers of FR4 (epoxy) printed circuit board (PCB) with a thickness (h) of 1.6 mm, a dielectric constant (εr) of 4.4, and a dielectric loss factor (tan) of 0.02 with dimensions of 35 mm × 48 × 1.6 mm . This antenna is simulated using CST software. The design of the Studio Suite 2018 antenna is done by adjusting the size of the slot spacing, the length of the slot, the size of the ground clearance, and the size of the board length. In this antenna design, the slot size can be increased on the left side of the patch to increase the slot pitch for a deeper return loss, and the right side of the patch to increase the slot pitch for a shorter return loss. The results in the simulation process obtained good working frequency, bandwidth and return loss, the antenna can operate at the expected frequencies, namely 2.4 GHz, 3.2 GHz, 5.1 GHz with a return loss of -42 dB, -44 dB, - 31 dB. Bandwidths 114.4 MHz, 121.2MHz and 287.9MHz.","PeriodicalId":182397,"journal":{"name":"Elektron : Jurnal Ilmiah","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125311926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This grounding system aims to protect humans, electrical equipment, and electrical installations from the danger of electrical short circuits. In compliance with official regulations, safety standards and according to general electrical installation regulatory standards (PUIL) to avoid the danger of lightning strikes in buildings, it is necessary to have grounding resistance value of less than five ohms and is made as small as possible. In this study, the measurement of grounding resistance seen from the depth of the grounding and the grounding resistance are arranged in parallel. The results of this study indicate that the parallel grounding resistance method produces a more significant reduction in the value of grounding resistance compared to the grounding resistance in a certain depth From the calculation results, the resistance value of the Electrical Engineering Building at Andalas University using a rod electrode with a diameter of 0.016 meters is 24.5 Ω with an electrode depth of 0.5 meters and at a depth of 1 meter a grounding value of 17.52 Ω is obtained.
