The selection of lightning rods in the Nusa Dua Highland housing estate aims to securethe housing area from lightning strikes, because the housing has not been protected by lightningrods and earthing system components which are very difficult because they have rocky soil types.The average number of lightning strikes per year with a density value of 31 per km2 and populationdensity, land use for houses and buildings have a very high level of vulnerability, so lightning rodsare needed to secure the Nusa Dua Highland residential area. Lightning rods to be used areconventional lightning rods or Evo Franklin (E.F). The selection of the type of lightning rod is done byanalyzing technical and economical. The results achieved in this study are the type of lightning rodsuitable for housing Nusa Dua Highland is the E.F lightning rod with an earthing system. Becausefrom technical analysis, 1 E.F lightning rod is able to protect the entire residential area with 37,994m2 of protection area from the 22,444 m2 housing area, while 1 conventional lightning rod is onlyable to protect 1 house from a total of 147 housing units. In terms of economical cost of installing E.Flightning rods is much cheaper at a cost of Rp. 104,450,000. Conventional lightning rods cost Rp.14,390,000 for 1 housing unit and to protect the entire housing using conventional lightning rodsneeded 147 lightning rods at a cost of Rp. 2,115,390,000.

Inductive load with low power factor has led to the greater load current so that it is required a power factor improvement. Improvement of power factor in inductive load can be carried out by installing capacitor according to required proportion. Installation of capacitors can be used in parallel or series to electric source.The method of making design is divided into two parts, namely, the first is the designing of hardware and the second is the designing of the software. The designing of hardware consists of designing the power supply circuit, driver relay circuit, LCD circuit, minimum system circuit of ATmega 328P, capacitor bank circuit, current sensor circuit and voltage sensor circuit. The sensors used in this study were a non-invasive type SCT013-010 current sensor and a voltage sensor of a 500 mA type zero transformer. The design of software was in the form of work program tools that use the application of Arduino IDE. LCD displays the readout values of voltage, load current, active power, apparent power, reactive power and power factor. The ATmega 328P microcontroller processes data and determines the working relay so that the purpose of power factor value by cos phi ? 0.85 is achieved. The results achieved in this research is the design of automatic bank capacitor based on microcontroller of ATmega 328P can improve power factor by conducting injection capacitor to raise the power factor value according to PLN standard by cos phi ? 0.85 by connecting capacitor to the source of PLN paralleled by a single phase inductive load.

Electromagnetic launchers are devices that use electromagnetic forces to launch high-speed projectiles, utilizing accelerated armature shifts along with a pair of conductive rails. Electromagnetic launchers have been studied as high-speed ballistic launchers for various applications such as military weapons to space launches. Based on the development of capacitor technology and the limited development of electromagnetic launchers, especially in the field of launching high-speed projectiles with capacitor supply as the development of electromagnetic weapons technology, research was carried out by making the design of electromagnetic launchers with capacitor supply to produce high-speed projectiles (more than 180m/s based on variations in rifle bullet speed) as the development of electromagnetic weapons technology. The results of the research on the design of electromagnetic launchers with capacitor supply obtained the final projectile velocity value of 200,644 m/s, which consists of three main components namely the rail system, the gas injector, and the supply system.

Gangguan hubungasingkat tenaga listrik ditimbulkan oleh hubung singkat tigaafaseasimetris, gangguan hubung singkat tidak simetris satu fase ke tanah dan gangguan hubung singkat tidak simetris antar fasa dan dua fasa ke tanah. Gangguan tersebut telah menyebabkan beberapa trip, kegagalan kerja relay dan recloser. untuk menentukan setting waktu kerja relay arus lebih dan recloser agar peralatan proteksi dapat bekerja dengan baik dilakukan simulasi gangguan hubung singkat pada beberapa titik lokasi gangguan yang dipilih berdasarkan kondisi di jaringan penyulang Mambal. Berdasarkan analisis, arus gangguan hubung singkat dipengaruhi oleh jarak tittik gangguan, semakin dekat titik gangguan dengan sumber maka semakin besar arus gangguan hubung singkat pada titik tersebut. Arus gangguan maksimum dan minimum hubung singkat mengakibatkan selisih waktu kerja relay di tiap lokasi dengan selisih waktu TMS selama 0,4 detik. Dilakukannya setting sistem proteksi pada penyulang Mambal sesuai dengan hasil analisis dapat memperbaiki selektifitas sistem proteksi pada Penyulang Mambal.

The single phase to ground fault on the 150 kV transmission line GIS Pesanggaran –Nusa Dua Substation has a high fault impedance so that the distance relay as anauxiliary safety device cannot detect the disturbance. Directional Ground Relay (DGR)was chosen as an auxiliary protection relay to secure the system from single phase toground faults. Installation of auxiliary protection relays requires planning and relaysetting steps to obtain Iset, TMS and trip time. The calculations that have been carriedout get the results of DGR setting with a pickup current range of 0.0522 – 0.0722 A.DGR will work after 2.297 seconds if the differential relay as the main protection relaydoes not work or fails and the distance relay as a backup protection does not succeed insecuring a single phase fault to ground as well.
