A harmonic is emerged due to a high level of non-linear load usage which was the main problem on the quality of electric power. On the other hand, it is also lead to an adverse impact for the electric power system such as the wave form and voltage were not sinusoidal. Then, in order to reduce it, an active filter could be used as one of the best way. This research focused on the simulation of PID (Proportional Integral Derivate) Controller towards an active filter to reduce the harmonic and MATLAB R2013 software that applicated as the instrument. As the result,the usage of PID Controller on the active filter could reduce the THDi into 1.89% and THDv into 0.59 % as an average percentage at Bali National Golf Resort.

Fires will arise due to a decrease in the surface of the water resulting in the top layer of peatland becoming dry. Manually monitoring ground level is very difficult. The solution is to make a remote water level monitoring prototype in order to be able to regulate irrigation on peat land and make the system open and close the irrigation door during the dry season and when the rainy season arrives. The design of groundwater level monitoring uses a program installed on the Arduino Uno microcontroller.Water level data is sent by prototype via GSM SIM 800L network, 8 level conditions that have been determined from a depth of 15 cm multiples of five so on to 55 cm. HC-SR04 Ultrasonic Sensor is a detector for water level. Data can be accessed at any time via SMS by sending "Check" to the prototype.

The AF building and building A are supplied from sources on the transformer which are joined with other faculties, while Buildings B, C, D and E are fed by one transformer No. 124303818 with a capacity of 160 kVA. The plan to build an Alumni Building does not yet have electricity. Based on the analysis of the design, the total amount of power needed in all buildings in the Sudirman Denpasar Faculty of Engineering is the result of the AF Buil...

Lately the quality electrical system has begun to decline with frequent interruptions such as the breakdown of electricity to the load, unbalanced load, THD current exceeds the standard, the fuse on the incoming to the parent panel and the fuse on the main panel is often burned, the grounding system resistance value exceeds the standard equipment value, cable temperature exceeds the standard, even voltage rises to 500 volts. The purpose of this study is to determine the causes of disruption of electricity, and produce a new master installation design to improve the system. Based on the results of the analysis, it was found that the importance of channel separation between ...

Kebakaran gedung diakibatkan oleh listrik sering terjadi. Kebakaran tersebut diakibatkan beberapa hal seperti : instalasi yang tidak sesuai standar PUIL, penggunaan kotak kontak menumpuk, pemeliharaan instalasi kurang teratur, umur instalasi melebihi standar. Permasalahan tersebut penting diatasi dengan melakukan sosialisasi keamanan instalasi listrik bagi masyarakat untuk menghindari terjadinya bahaya kebakaran pada gedung. Pemahaman tentang hemat energi juga penting bagi masyarakat agar masyarakat dapat menghemat biaya listrik. Sasaran dari pengabdian ini adalah masyarakat yang sehari-hari mengoperasikan peralatan listrik di Banjar Tingkih Kerep, Kecamatan Penebel Kabupaten Tabanan. Berdasarkan hasil pelaksanaan pengabdian kepada masyarakat dari kegiatan persiapan hingga pelaksanaan yang dilaksanakan pada bulan Agustus sampai bulan Nopember 2017, sosialisasi bertempat di Balai ...

A harmonic is emerged due to a high level of non-linear load usage which was the main problem on the quality of electric power. On the other hand, it is also lead to an adverse impact for the electric power system such as the wave form and voltage were not sinusoidal. Then, in order to reduce it, an active filter could be used as one of the best way. This research focused on the simulation of PID (Proportional Integral Derivate) Controller towards an active filter to reduce the harmonic and MATLAB R2013 software that applicated as the instrument. As the result,the usage of PID Controller on the active filter could reduce the THDi into 1.89% and THDv into 0.59 % as an average percentage at Bali National Golf Resort.

Fires will arise due to a decrease in the surface of the water resulting in the top layer of peatland becoming dry. Manually monitoring ground level is very difficult. The solution is to make a remote water level monitoring prototype in order to be able to regulate irrigation on peat land and make the system open and close the irrigation door during the dry season and when the rainy season arrives. The design of groundwater level monitoring uses a program installed on the Arduino Uno microcontroller.Water level data is sent by prototype via GSM SIM 800L network, 8 level conditions that have been determined from a depth of 15 cm multiples of five so on to 55 cm. HC-SR04 Ultrasonic Sensor is a detector for water level. Data can be accessed at any time via SMS by sending "Check" to the prototype. The results of the tests performed indicated that the tool can function in accordance w...

Solar energy as a source of renewable energy has enormous potential, especially in Indonesia. Balinese architecture-based roof pattern has 4 fields, the north and south side are trapezoidal and the east and west sides are triangular with 350 roof inclination angle. One of Bali's traditional buildings is Bale Sari, which is a case study with an area of ??32.64 m2, length 6.40m and width 5.10m. Bale Sari's roof has a pyramid pattern, each side having the same length and width. Methods performed in this study with manual calculations to find the potential maximum power. The total number of solar panels used is 234 pieces. With this amount, obtained the best potential results on the southern side, with an average power gained of 667.67 Watt. The results are obtained when the sun is at a maximum warming point or precisely when the...

Selain itu, penyulang ini memiliki trafo distribusi sebanyak 105 buah dengan total jumlah pelanggan mencapai 11.800 pelanggan. Untuk melindungi penyulang dari gangguan surja petir , maka dipasang Arrester Multi Chamber pada tiap tiang gawang pada saluran distribusi untuk melindungi saluran distribusi pada Penyulang Pecatu. Pemasangan Arrester Multi Chamber di penyulang Pecatu dengan tujuan, yaitu mengetahui bagaimana data teknis dan kinerja dari pemasangan Arrester Multi Chamber di sepanjang jaringan distribusi di penyulang Pecatu dan mengetahui data gangguan yang ditimbulkan oleh sambaran petir. Dengan penempatan arrester sekitar berjarak 200 m di setiap empat sampai lima gawang , diperoleh kenaikan tegangan saat mengalami surja petir dengan kecepatan gelombang 4/10 µs, dengan waktu sampai kepuncak 10 µs, dimana dengan arus surja 65 kA yaitu 4.147,1831 kV, ...
