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.Â Keywords : gas insulated switchgear, equilateral, foreign particles, electric field, eccentricity ratioAbstrakPaper ini menganalisa tentang pengaruh keberadaan partikel asing pada peralatan hubung isolasi gas/ gas insulated switchgear (GIS) 3 fasa susunan equilateral.

Techno-Economic Simulation of On-grid PV System at a New Grand Mosque in Bukittinggi using HOMER Pinto Anugrah; Rizki Wahyu Pratama

Mosque is an important building for Muslims worldwide for doing religious activities, such as daily prayers, weekly discourses, and annual celebrations. In many places, mosques are considered appropriate buildings for rooftop solar photovoltaics (PV) installation. This study provides a techno-economic analysis of an on-grid PV system in a great mosque. As a case study, Masjid Tablighiyah Garegeh in Bukittinggi is chosen, which is currently under construction with an expected capacity of up to 1,400 people. This study uses HOMER software as a tool to assess optimum configuration for an on-grid PV system. There are four options that is considered in this study: PV-grid, PV-battery-grid, battery-grid, and grid only system . Optimization results showed that both configurations with PV have promising performance; however, an on-grid PV system without battery system is the most optimum configuration. A 40 kWp PV equipped with a 27 kW converter has the least net present cost with USD 6,902, while the cost of energy when implementing the system is only about USD 4.8 cent per kWh. By implementing the system, 57.2 MWh of electricity will be produced from the PV.

Pemanfaatan teknologi informasi dan telekomunikasi (ICT) perancangan, implementasi, pengembangan, dukungan atau manajemen sistem informasi berbasis komputer terus pada aplikasi perangkat keras atau hardware dan perangkat lunak atau software, sebagai media promosi dan komunikasi di Indonesia sangat dibutuhkan. Pelaksanaan kegiataan ini, merupakan kelanjutan dari program departemen teknik elektro untuk pengabdin berbasis KBK. Pada kegiatan ini, diaksanakan pelatihan penggunaan media informasi berbasis android yaitu berupa running text yang digunakan untuk mengupdate informasi kondisi mushalla di Almahira. Pengunaan teknologi informasi dan telekomunikasi (ICT) terutama teknologi berbasis android dengan menggunakan internet merupakan cara yang inovatif dalam melaksanakan berbagai macam kreatifitas yang dapat dilakukan di berbagai sektor. Dengan memanfaatkan teknologi berbasis android, maka dapat dilakukan berbagai kegiatan secara elektronik seperti running text, media forum, email, mailing list dan berbagai aktifitas lainnya. Mushalla Al Mahira adalah tempat shalat berjamah yang dilakukan oleh sebagian kecil masyarakat yang terletak di RT 01 / RW 07 Aie Pacca Padang, merupakan salah satu tempat ibadah umat muslim yang masih belum menggunakan teknologi berbasis android, sehingga proses mengupdate informasi belum dapat dilakukan dengan teknologi. Agar Jamah Mushalla Al Mahira dapat juga merasakan perkembangan teknologi, maka tim pengabdian dari KBK telekomunikasi Jurusan Teknik Elektro Unand, memberikan pelatihan penggunaan teknologi berbasis android, berbentuk running text sebagai media update informasi kegiatan di Mushalla Al Mahira Aie Pacca. Running Text ini bertujuan untuk memudahkan jamah membaca perubahan setiap informasi, jika sewaktu waktu informasi ada yang terbaru.

The correlation between lightning and several weather parameters (rainfall, humidity, air temperature, and wind) in Padang from 2016 to 2020 was statistically analyzed. Lightning data and weather parameters were obtained from two electric field mills (EFMs) and the meteorology, climatology, and geophysics agency (BMKG), Indonesia. The study results show that the highest lightning occurred in November during the wet season. The correlation coefficient between lightning and rainfall during the wet and dry seasons was 0.52 and 0.26, respectively. Furthermore, the correlation coefficient of lightning with humidity, air temperature, and wind during the wet and dry seasons was 0.25, 0.06, 0.15, and -0.45, 0.25, -0.02, respectively. These results indicate a strong relationship between lightning and rainfall during the wet season; rainfall is the only primary variable in lightning frequency.
