Kemajuan teknologi saat ini mampu membuat sistem keamanan dapat terhubung dengan jaringan internet, dengan adanya sistem keamanan yang dapat terhubung oleh jaringan internet maka dapat mencegah terjadinya tindak pencurian dikarenakan dapat melacak keberadaan motor yang di curi oleh orang lain. Penelitian ini berhasil membuktikan, “Perancangan Sistem Keamanan Sepeda Motor Berbasis RFID Starter Sistem Dengan Implemantasi GPS Tracking Menggunakan Arduino”. Perancangan sistem keamanan sepeda motor pada penelitian ini dilakukan menggunakan sensor RFID yaitu dengan cara menyalakan motor dengan E-KTP. Ketika motor tersebut itu hilang maka kita bisa melacaknya melalui sensor GPS Ublox Neo di motor tersebut lalu kita bisa melacak titik koordinat posisi motor dengan google maps.
Electrical energy is a necessity that is needed by everyone. To ensure the reliability of electrical energy, the electrical equipment used must be regularly maintained. One of the maintenance carried out is testing the SF6 gas on the power breaker (PMT). This test is carried out to determine the quality of SF6 gas which functions as an insulation medium for PMT. Because when there is a fault current or a normal current at the time the PMT is cut off, an arc will arise which can damage the PMT equipment itself. Therefore, the quality of SF6 gas in PMT must be maintained under normal conditions. In the SF6 gas test, the SF6 Multi Analyzer test tool is used which functions to ensure that the quality of the SF6 gas at PMT is still in good condition. In routine maintenance activities, SF6 gas testing is carried out at 66 kV PMT which is in the 4R2 Reactor Bay. From the test results, the gas purity value of SF6 is 99.9%, the product decomposition or SO2 content of SF6 gas is 26 ppmv, the dew point value is -21.2 ºC, and the pressure value is 0.735 MPa. Based on the test results, there is an anomaly in PMT, namely the results of the SO2 content test in SF6 gas are not normal. The SO2 value exceeds the predetermined standard limit, which exceeds the maximum limit of 12 ppmv. Therefore, in accordance with the analysis of the FMEA method, that is, if there is a bad quality test result for SF6 gas, then SF6 gas replacement and SF6 gas purity testing must be carried out so that there is no widespread disturbance and to ensure the reliability of the electric power distribution system. After replacing SF6 gas, the test results show the value of SO2 = 0 ppmv.
ABSTRACT The occurrence of harmonics is caused by the non-linear operation of the electrical load. The level of harmonic distortion or what is called Total Harmonic Distortion (THD) in a transformer can cause losses that affect the efficiency of the transformer. In this study, THD measurements were carried out on four transformers at Tzu Chi Hospital. This research was conducted using observation, documentation, and direct measurements in the field to analyze within the limits of the IEEE 519-2014 standard. The purpose of this study was to analyze the main electrical system at Tzu Chi Hospital, analyze the value of Total Harmonic Distortion (THD) for voltage analysis. and currents at Tzu Chi Hospital. THDv based on the measurement results are transformer 1 4.8%, transformer 2 2.48%, transformer 3 1.51%, transformer 5 5%. While the THDi results obtained after measurement are transformer 1 20.2%, transformer 2 29 ,4%, transformer 3 14.78%, transformer 5 37.8%. Even after measurement, THDv was found to conform to the IEEE 519-2014 standard, and THD was found to be non-compliant with the IEEE 519-2014 standard. ABSTRAK Timbulnya harmonik disebabkan oleh operasi beban listrik non-linier. Tingkat distorsi harmonik atau yang disebut dengan Total Harmonic Distortion (THD) pada suatu trafo dapat menimbulkan rugi-rugi yang mempengaruhi efisiensi trafo. Pada penelitian ini dilakukan pengukuran THD pada empat trafo di Rumah Sakit Tzu Chi. Penelitian ini dilakukan dengan metode observasi, dokumentasi, dan pengukuran langsung di lapangan untuk menganalisis kesesuaian dengan batasan standar IEEE 519 2014. Tujuan dari penelitian ini adalah untuk menganalisis sistem kelistrikan utama di Rumah Sakit Tzu Chi, menganalisa perhitungan nilai Total Harmonic Distortion (THD) untuk tegangan dan arus di Rumah Sakit Tzu Chi. THDv berdasarkan hasil pengukuran yaitu transformator 1 4,8%, transformator 2 2,48%, transformator 3 1,51%, transformator 5 5%.sedangkan THDi hasil yang didapat setelah dilakukan pengukuran adalah transformator 1 20,2%, transformator 2 29,4%, transformator 3 14,78%, transformator 5 37,8%. Bahkan setelah pengukuran, THDv diketahui sesuai dengan standar IEEE 519 2014, dan THDi diketahui tidak sesuai dengan standar IEEE 519 2014.
