The type of load contained in the electrical system at Bali National Golf Resort is a nonlinier load. on-linear loads, it can cause harmonics and make a decrease in quality of electricpower. Harmonics can be bad impact for the sinusoidal shape of current and voltage waves andthen making the electrical system abnormal. To reduce harmonics we need the addition of anactive filter. This research will focus on simulating the use of Fuzzy Logic Controller on activefilters to reduce harmonics. The simulation is done using MATLAB R2013 software. As theresults, The usage of Fuzzy Logic Controller on active filter are able to reduce the harmonicswhere the current and voltage harmonic values fall, average to 0,86% and 0,11%.

Many hydropower plants today are built on a large scale. Meanwhile, the construction of thislarge-scale power plant requires a very large area and a very high head. This has an impact onthe difficulty of distributing electrical energy to remote areas, on the other hand, there are stillmany small rivers in remote residential areas that have not been fully utilized as an alternativeto potential sources of electricity generation. So to overcome this, through this research aprototype Micro Hydro Power Plant (PLTMH) was made using a Cross-Flow turbine which ofcourse can be applied to rivers that have a fairly low flow and head. In this study, the results ofthe calculation of the PLTMH prototype parameters with a Cross-Flow Turbine were designedat an effective head of 6 meters. The design of the Cross-Flow Turbine uses a runner outerdiameter of 0.15 meters, a runner inner diameter of 0.10 meters, and the number of blades is18. The test results obtained 574,6 rpm of turbine rotation before coupled with the generator;489 rpm rotation of the turbine after coupling the generator; 3309.2 rpm of turbine rotation,36.52 V output voltage at no load, and 386.4 rpm maximum turbine rotation; 2584.4 rpmmaximum generator rotation; 28.18 V maximum output voltage; 0.422 A maximum outputcurrent; 10.59 Watts of maximum output power; 0.312 Nm of maximum torque; 8,026%maximum efficiency at load.

PLTMH is a type of generator that utilizes water resources for its workings. Utilization ofwater resources is still minimally carried out by the community, especially by students ofElectrical Engineering at Udayana University because it must be implemented directly on alarge enough river flow so that it is difficult to study. So, in this study, a prototype modeling ofMHP using a Kaplan turbine was designed which is useful for the learning process before beingimplemented directly in the river. The Kaplan turbine prototype is designed with a head of 2 m,an input pipe of 2xdimxand a discharge of 12 L/s, has a total of 30 guide blades,xwith an openingangle of 30o, with a lengthxofx0.05 meters, a widthxof 0.045 meters, an inside diameterxofx0.33metersxandxan outerxdiameterxofx0.42 meters.

Sistem pengangkat air dengan menggunakan sumber pembangkit listrik tenaga surya sudah banyak dilakukan oleh beberapa orang atau kelompok, namun pada malam hari panel surya tidak dapat mensuplai mesin pengangkat air karena tidak mendapatkan sinar matahari. Permasalahan yang terjadi adalah tidak dilengkapi dengan penyimpanan energi untuk sistem pengangkat air tersebut. Solusi untuk masalah ini adalah dengan membuat rancang bangun baterai charge control untuk sistem tersebut. Metode dalam pembuatan sistem ini dibagi menjadi dua bagian yaitu perancangan hardware dan software. Hasil dari sistem charge control ini mampu melakukan pengisian untuk aki GS 12V10Ah dengan arus pengisian mengikuti arus dari PLTS dengan rata-rata arus pengisian sebesar 2,065 ampere dan tegangan pengisian yang diberikan 13V selama 2 jam dan lama pemakaian aki GS 12V10Ah untuk membackup beban pompa 60 Watt selama 1 jam 45 menit.

A disturbance in the groundhing system is caused by a disturbance current which isflowed to the ground which will cause a difference in tension on the ground surface dueto high ground resistance. On rocky soils with ground resistance in excess of 200 ?-meters it is very difficult to determine a suitable grounding system. The purpose of thisresearch is to analyze the design of an appropriate earthing system on narrow land onrocky ground which will be used as a reference for selecting the grounding system at atKampus Unud Jimbaran feeders. The method used is to take measurements on rockysoil then measure and determine the proper earthing design to use. The optimal resultsobtained for the grounding system on narrow land on rocky soil is a grid groundingsystem because it produces the lowest earthing resistance value in dry soil conditionsand wet soil conditions, namely 0.6269 ohms on dry soil and 0.4314 ohms on wet soil. has met the standard according to IEEE std 80-2013, which is <1 ohm with 16x16 rodsin an area of 4 m2.

is one of the regions with potential renewable energy sources, includinghydropower, namely the Micro Hydro Power Plant (PLTMH). The main problem with hydropoweris the flow of water that does not flow continuously throughout the year. A micro hydro that isplaced in a certain location requires a turbine in accordance with the characteristics of theexisting location. In this study, a turbine was designed to obtain a new type of Snail-Lie turbinethat accommodates all existing location parameters. In this turbine, there are variations in theform of gaps or spaces in each particular blade to trap water so that it can increase the torque,where this torque will affect the turbine output. The research method used is to findmathematical models of the Snail-Lie 4 Snail and 8 Snail turbines, make a prototype model tobe tested in the laboratory, make a real Snail-Lie turbine model for field trials. The resultsshowed that the addition of the number of snails from 4 snails to 8 snails caused the turbine'sperformance to increase, this is because the number of snails will affect the performance of theturbines, because the snail functions as a water trap so that it can be used as thrust for theturbine when it rotates. The highest output obtained is at the nozzle position 0° and the nozzleangle of 20° using a snail-lie 8 snail tubing which produces 166.9 rpm turbine rotation, 1086.8rpm generator rotation, 0.707 volt generator voltage, 0.189 watt generator power, and torqueamounting to 0.01 Nm, and an efficiency of 20.8%. The low efficiency value obtained in thesystem is 20.8% because the water entering the turbine is not comprehensive, the slip occurs inthe turbine that is coupled with the generator through the fan rope and the generator has its ownefficiency.
