Identify potential energy savings is one way to optimize the supply and use ofenergy in industrial sector. Electrical energy supplied by PT. PLN (Persero) withinstalled power capacity of 30,000 kVA. Electrical energy to the productionprocess with a voltage of 20 kV through 11 (eleven) units transformer. Based onthe results of power quality measurements with HIOKI 3197 and HIOKI 3286-20show as seen in the previous section, it can be seen that: (a) load unbalancesseen from the voltage and current in the transformer MCC-01 and thetransformer E-34. (b) magnitude fluctuating voltage on the main transformerphase S and T. Even the relatively high voltage (up to 233 V) on the transformerlighting. (c) the power factor is around 0.92 is good enough, but the power factorat the transformer low enough E-34 which reached 0.56. The power factor ontransformer lighting value -1 (leading). (d) total harmonic distortion (THD) voltageand current transformer at some fairly high beyond the limit of tolerance. Thereare several potential energy savings that can be identified, among others:decrease the voltage and current THD, reduction of reactive power consumptionin lighting, improved load balancing.Kata kunci: energi, listrik, faktor daya, penghematan, filter harmonic

Primary energy used in the production process of PT. Textile Industries is the electric energy and thermal energy. The electrical energy supplied by PT. PLN (Persero) with contractual power of 5540 kVA, and has 5 units with a capacity of 2500 kVA transformer (1 unit), 2,000 kVA (2 units), and 1,250 kVA (2 units). From the analysis of several potential energy saving electrical system supply side can be recorded as follows: An unbalanced load can result in decreased system efficiency by 2%. Optimizing the performance of the capacitor bank regulators so that the work factor to achieve an optimum value (0.9). Losses incurred due to the low power factor can be calculated based on the following approaches: Losses = [1 -{pflow/pfhigh}2] x 100%. Losses in the transformer-1 (2000 kVA) is 479.8 kW, transformer-3 (2000 kVA) is 834.2 kW, transformer-4 (1250 kVA) is 521.4 kW, and transformer-5 (1250 kVA) is 125 kW. Current THD (total harmonic distortion) reduction to < 5%. Replacement tranformator so in accordance with the optimum loading and maximum efficiency from 9000 kVA to 6660 kVA. This replacement will reduce losses as high as zero load is usually equal to 3%.

Indonesia as the biggest geothermal potential country in the world. There are252 geothermal locations have been identified that distributed along a volcanicbelt extending from Sumatera, Java, Nusa Tenggara, Sulawesi, Maluku untilPapua. Utilization of this energy be side for electrical power generation, it is usedfor non electrical (direct uses) as well. In the agriculture area with high rainfall,drying process can decrease quality of crop products. The tools doesnÃ¢â‚¬â„¢t produceemission and doesnÃ¢â‚¬â„¢t make noises and also as clean energy. By optimization theutilization of geothermal energy that available surrounding the agriculture areacould increase the local people economic.

Chlorine is a chemical substance, which has been used in many industriesfor a long time, especially in the pulp and paper industry and drinking watertreatment. Chlorine has been used in making dye, medicine, plastic, solvent and dry clean. In the sector of energy and electricity, chlorine is used in the cooling water system. Due to the lack of condition of chlorine’s storage, it will lead to the leakage of chlorine gas, which will endanger environment and health. Waste from industrial activity containing chlorine has a potential to damage environment. Chlorine also can easily react with many compounds because of its character as a strong oxidator. If chlorine and organic compounds are bound to each other, they will cause carcinogenic effect. Based on the consideration of the danger of chlorine on environment and health, many countries in the world strive to reduce its use in industries. Many alternatives and technologies have been developed to alternate the function of the chlorine.

Fuel cell is a device which is purposed to convert chemical energy into electric energy and produce water as side result. Fuel cell technology doesn’t produce emission and doesn’t make noises and also as environmental friendly energy has a high efficiency until 45% in fuel conversion to electricity, and it can be higher until 60% – 80% if it isco-generation. A fuel processing system converts hydrocarbon or other organic fuels to hydrogen of composition and purity suitable for fuel cell operation. The fuels include petroleum derived liquids, such as naphtha and gasoline, petroleum derived gases, such as methane and propane, and other fuel such as methanol and ethanol. The electrolyte in the center allows only the protons to pass through the membrane to the cathode side of the fuel cell. The electrons cannot pass through this membrane and flow through an external circuit in the form of electric current. As oxygen flows into the fuel cell cathode, another catalyst helps the oxygen, protons, and electrons combine to produce pure water and heat.
