Water energy is energy that comes from water flow which is used to produce electricalenergy by using a flow of water that flows to turn a turbine, then the turbine is connected to agenerator. Micro-hydro power plants are usually built in areas that have the potential for generatingelectricity in a small capacity. The choice of location of a micro hydro power plant is largelydetermined by the potential for water fall or often called a waterfall. Parameters that can be changedto improve turbine efficiency are the shape of the turbine blade, turbine blade volume, nozzle angle,and nozzle position. The method used is the method of observation by observing and testing directlyand the method of literature by studying the literature - literature from several references.Performance characteristics of nest-lie turbines produce higher torque values than triangular turbineblades. Nest-lie turbine produces a torque value of 0.0076 Nm at position 450 nozzle and nozzle angle100. This shows that the nest-lie turbine has characteristics that are better than a triangular turbineblade.

The purpose of the Economic Dispatch is to determine the distribution of each unit inproviding the requested load, so that the load demand can be met at the lowest possible cost takinginto account the limitations of the generator and available system. Commonly the researcher usesome methods to solve economic dispatch, such as Lagrange, Genetic Algorithm (GA), and othersoptimization methods. Latest Artificial Intelligent technology had invented the solution to solve theoptimization problem especially for economic dispatch, its named Imperialist Competitive Algorithm(ICA) which in this project, ICA become the solution to solve economic dispatch problem in Bali 150kV interconnection system. The simulation result the compared by the result using Lambda Iterationand Particle Swarm Optimization (PSO) method. Simulation result show that the ICA method is ableto provide a better solution in Bali 150 kV interconnection system. The difference in generation costsbetween the Imperialist Competitive Algorithm (ICA) method and the Particle Swarm Optimization(PSO) method is 1685.19 $/h or savings are made at 0.24%. While the difference in generation costsbetween the Imperialist Competitive Algorithm (ICA) method with the Lambda Iteration method is7116.45 $/h or savings are made at 1.03%.

The increasing need for electrical energy every year results in the availability of energysources is dwindling. Therefore, the need for energy conservation to streamline the use ofelectrical energy without reducing its comfort or productivity. The main factor of energyconservation is energy auditing. Plasa Telkom Teuku Umar is a company engaged intelecommunications. The convenience of employees and customers takes precedence overthis0company.0The best service0must also be followed by the efficient use of facilities. For thisreason, an electrical energy audit is needed. In this study, it was attached0to theair0conditioning0system and lighting system. It is attached to the air conditioning system andlighting system. Tools0that can be0used for measurement in the field are Lux Meter, (lightintensity measurement), Tang Ampere (electric current measurement), and Thermometer (roomtemperature measurement). The study was conducted by0calculating and comparing0electricalenergy consumption in lighting and air conditioning systems between before and after anenergy audit. Calculate the pre- and post-audit IKE (Energy Consumption Intensity) andcompare it to the IKE standard. The results of the study found energy savings of 36.06%. Fromelectricity usage of 16.86 kWh/m2/bln pre audit to 10.78 kWh/m2/mo post audit.

Pusat Listrik Tenaga Diesel Gas (PLTDG) Pesanggaran menjadi salah satu pembangkit yang ada di Bali yangmempunyai posisi penting dalam sistem 150 kV Bali, kinerja kestabilan dari PLTDG Pesanggaran saat terjadigangguan merupakan hal krusial yang perlu diperhatikan. Pendekatan model SMIB untuk analisa kestabilanpada PLTDG Pesanggaran digunakan untuk memudahkan analisa, dengan cara mereduksi sistem multimesinmenjadi SMIB dengan Losses Concept. Dari hasil simulasi model tersebut diperoleh hasil bahwa nilai overshootdan settling time dari tanggapan perubahan sudut rotor dan tanggapan frekuensi pada model SMIB PLTDGPesanggaran.

ANALISIS STABILITAS MULTI MACHINE PADA ISLAND MODE SISTEM KELISTRIKAN BALI I Gede Bayu Suarsa; Ida Bagus Gede Manuaba; Rukmi Sari Hartati

Modern electrical systems are characterized by extensive interconnection systemswith the need for electrical energy and control depending on the control system. Oneelectricity system that has been widely interconnected is the Bali electricity system. The Balisystem using island mode has four generating units that can supply electrical energy needsincluding UP Pesanggaran, UP Celukan Bawang, UP Gilimanuk and UP Pemaron. But itmust be remembered in supplying electrical energy needs are also affected by the constantchange in load, resulting in instability in the electrical system. So the need for a controlsystem that can increase the value of damper such as the Power System Stabilizer (PSS). PSScan be used to reduce frequency oscillations when interference occurs, but for PSS design itgives less good performance in different operating conditions. Problems with PSS occur dueto errors in modeling, input value input, and topology variations. Efforts are made to reduceerrors in PSS by using methods that are expected to overcome this problem, namely the fuzzylogic controller.The results of the analysis show that the system performance index usingfuzzy logic is 78.6064. Fuzzy logic has the ability to damp better and reduce errors better.

Energy audit is a technique used to determine the amount of energy use in a buildingand to find various energy-saving solutions or opportunities. In this study, the energy audit wasconducted at PT. Graha Sarana Duta II Denpasar which is located on Jl. Serma Gede No. 13,Dauh Puri Klod, Denpasar. Based on the existing conditions, the level of Energy ConsumptionIntensity (IKE) obtained before the audit was carried out was 245.22 kWh/m2/year or 20.43kWh/m2/month which according to ESDM No. 13/2012, Air-conditioned buildings are in thewasteful category. In this study, the energy audit focuses on the lighting system and airconditioning system. The method used in this research is to calculate and analyze theconsumption of electrical energy in the lighting system and air conditioning system. After doingthe research, it can be seen the energy saving opportunities (PHE) in PT. Graha Sarana Duta IIDenpasar by replacing the TL and SL lamps using LED lamps and requiring room users to turnoff the air conditioner when the room is not in use, the result is savings 11,4% in electricalenergy use, where the IKE after the audit is 18.1 kWh/m2/month. The office can also save thecost of using electrical energy, which is Rp. 3,170,394,- every month.
