Earthing systems (Grounding System) is a device that serves to secure the installation of overcurrent and overvoltage caused by lightning electricity or internal interruption of electricity by removing the payload to the ground. One of the factors that influence terhadapnilai prisoners earthing is resistivity value of the land. Mini-hydro power plants in Tukad Balian Tabanan regency require resistance value ? 2 Ohms. The purpose and benefits of the research was to determine the characteristics of the grounding system in the mini-hydro power plants in Tukad Balian Tabanan regency. And the benefits of this research is in order to get the data that can be used as a reference darii mounting / grounding system planning power plants Tukad Balian minihidor in Tabanan regency.Based on analysis of the calculation of the earthing system with some type used sebagau obtained the following results: by using a single type of rod electrodes (one rod) to obtain the results of the grounding prisoners ?2?, rod electrodes implanted deep as 13 meters. By using two types of rod electrodes (two rod) S> L to get the grounding ?2?, rod electrodes implanted with a length of 7 meters and the distance between the electrodes 9 meters. By using two types of rod electrodes (two rod) S <L to get the grounding ?2?, rod electrodes implanted with a length of 8 meters and the distance between the electrodes 2 meters. By using the type of plate to get the grounding ?2?, required as many as three pieces of plate with a depth of 1 meter. Using a type of grid to earthing ?2? result, a long electrode required 45 meter.

Perumahan Nuansa Kori Jimbaran disuplai oleh salah satu trafo distribusi KA1441 melalui Penyulang Jimbaran. Trafo KA1441 berlokasi di Perumahan Nuansa Kori Jimbaran dengan kapasitas 250 KVA. Jumlah seluruh pelanggan yang disuplai oleh trafo iniadalah 118 unit pelanggan dengan beban daya 450 VAhingga 2200 VA. Berdasarkan hasil pengukuran di dapat nilai tegangan terendah yaitu 176Volt lebih rendah dari tegangan sumber satu phasa ke netral (220 V) yang terjadi pada saat beban puncak dengandrop tegangan melebihi 5%. Sehingga perlu dilakukan rekonfigurasi pada jaringan di Perumahan Nuansa Kori Jimba-ran.Hasil analisis rekonfigurasi JTR (Jaringan Tegangan Rendah) dengan simulasi program ETAP Powerstation 7.5 yaitu di dapat nilai tegangan terendah sebesar 210 V atau drop tega-ngan ‘4,54% dari tegangan sumber 220 V dan rugi-rugi daya sebesar 5,6 kW. Nilai drop tegangan yang didapat setelah rekonfigurasi jaringansudah sesuai dengan standar (SPLN 72 Tahun 1987).

Proses penyaluran tenaga listrik tegangan tinggi memiliki dampak terhadap lingkungan sekitar saluran transmisi. Salah satu dampak penyaluran tegangan tinggi adalah timbulnya medan listrik di sekitar konduktor saluran transmisi. Kajian kuat medan listrik saluran transmisi 150 kV pada konfigurasi vertikal, dilakukan dengan melakukan perhitungan dengan menggunakan metode bayangan dan pengukuran kuat medan listrik di bawah saluran transmisi. Perhitungan dilakukan untuk mengetahui bagaimana karakteristik kuat medan listrik pada suatu titik di bawah saluran transmisi. Perhitungan kuat medan listrik tertinggi pada lokasi 1 sebesar 4283 V/m dan pada lokasi 2 sebesar 4521 V/m. Hasil pengukuran kuat medan listrik tertinggi pada lokasi 1 sebesar 4251 V/m dan pada lokasi 2 sebesar 4700 V/m. Perbedaan karakteristik hasil pengukuran kuat medan listrik pada titik dengan jarak yang sama, disebabkan pengukuran kuat medan listrik tidak dilakukan pada waktu yang sama, sehingga perubahan tegangan fase ke netral masing-masing fase konduktor mengakibatkan perbedaan hasil pengukuran.

Learned about the use of water resources as a micro hydro power plant is very importantto be carried out by Electrical Engineering students at Udayana University. At this time atConvertion Energy Laboratory there was not been a practicum about Mycro Hydro Power Plandue to the unavailability of guide practicum module and micro hydro power plant prototypes.Therefore in this research was design and build a Prototype of Microhydro Power Plan wich had18 buckets where had 5 cm width, 4,47 cm length, 1,6 height and the tickness was 0,28 cm.This prototype can made 4,5 L/s water discharge, 9,809 W Power, and the torque was 0,26 Nm. So that prototype had 1,48% efficiency. To make this prototype as a complete practicummodule was arranged practicum guide modules that was explain abaout Characteristic of MicroHydro Power Plan with Pelton Turbines.

I Gusti Ngurah Rai International Airport Bali previously had a Substation (SS) D which serves the electrical system for the operation of modified Sewage Treatment Plant, however that substation currently under development with the construction of SS VVIP which serves the electrical system for the operation of VVIP buildings and Sewage Treatment Plant. To maintain the security of equipment and humans around the SS VVIP building a good grounding system is needed with a grounding resistance value of <1 Ohm. Because the land at Ngurah Rai Airport is sandy land, the suitable grounding systems are Pelat, Mesh, Grid-Rod groundinh systems [1]. To get an R value <1 Ohm, an analysis of each grounding system is needed, namely Pelat, Mesh, Grid-Rod.The results of the analysis showed that the safest system was the Grid-Rod grounding system with a grounding resistance value of 0.3718 Ohm, a touch voltage value of 223.51 Volt, a step voltage value of 1188.69 Volt and a planning cost of Rp7,712,500. Based on the construction planning data of the SS VVIP Ngurah Rai Airport, the grounding system used is the same as the result of the analysis of the Grid - Rod grounding system.

The quality of universities, especially study programs in Indonesia is measured based on accreditation conducted by BAN PT. According to BAN PT the quality is measured based on 7 main standards, one of them is Student and Graduate. One of the problems that still be the subject of discussion related to student failure is about the students who graduated not on time. Students graduating not on time are students who can not complete their studies in accordance with the provisions of time given. The existence of a graduate student is not timely of course cause problems and potentially drop out that affect the quality of education and accreditation. A system that predicts students' graduation is required by evaluating their learning outcomes. The timeliness of graduating students can be done with data mining techniques to find graduation patterns of students who have graduated which then used as a basis to predict students' graduation in the next year. This study showed that Naïve Bayes was able to classify the correct data testing on average by 86.16% and 13.84% error. In addition, other information obtained from the data testing used that the students who entered from the PMDK Pass graduated on time as much as 40%, other paths graduated on time by 26.7%, and pass filter exam on time 13.3%.

Abstract-Information technology is currently growing very rapidly. Almost all agencies take advantage of the role of information technology. In the X agencies engaged in the social field of information technology as a goal that must be achieved. In order to create good government, an agency must be supported by good IT governance in order that information technology and business objectives are aligned and have added value for the agency. This study aims to measure the governance of IT services. This research is done because the agency X is now using IT services. The existence of good policies and procedures on the insight X can create a good service as well. This study uses the ITIL v3 framework that focuses on Service Operation domain. The ITIL framework is an IT services management guide. Measurement of maturity level using COBIT. The level of maturity in this governance audit is at level 3. Recommendations are given to achieve the expected targets within the ITIL framework. Keyword- Audit, ITIL V3, COBIT, IT Services

Water has many benefits for human life. One of the benefits lies on the agricultural sector. However, as the water source is decreasing, the needs of water for agricultural sector is increasing. Subak is therefore one of the solutions in agricultural field. Meanwhile, the existence of subak also rises some problems. In terms of water source management, subak can be very effective. Unfortunately, subak is not that efficient in the water use. Smart irrigation with fuzzy logic used becomes a solution which has been offered to manage the water use based on the needs the paddy. This system uses solar panel and battery. In addition, it is completed by the weather censor and humidity. This system works during rice planting period. The findings show that the water irrigation on subak rice field becomes more effective, efficient and optimizing the harvest.
