Abstract

Electrical loads have resistive, inductive and capacitive characteristics. This characteristic will have an impact on the electrical system, namely the power factor. The power factor value is limited from 0 to 1. If the power factor value is close to 1 (high active power), the electrical system will be better, and vice versa, if the power factor is low, it is close to 0 (high reactive power), so that less electrical power can be utilized from the amount of power looks the same. When the electrical system has a low power factor (large reactive power) it will affect the decrease in power quality and increase the use of electric power. In problem identification, it is found that there is a lot of use of electro motors or 3 phase electric motors which produce inductive loads and affect the power factor or cos phi. PLN has determined the minimum value of the power factor is 0.8. If the power factor is below 0.8 then consumers or factories that use it will be fined by PLN. The need for a capacitor bank that is used at a power capacity of 105 kVA with a cos phi of 0.9 is 22.33 kVAR.

Abstract

One of the Renewable Energy potentials that can be developed in Ketapang Regency is Micro Hydro Power Plant (PLTMH) in the form of a Waterfall, which is located in 3 (three) districts, in 5 (five) villages, with an average discharge of 0.1-0 , 2m³ / sec. And along the Pawan River Basin, there is enough potential for Micro Hydro Power Plants. From the economic point of view to help overcome the problem of electricity shortages, especially in rural areas. In an effort to help accelerate the electrification process of Ketapang Regency through rural electrification based on renewable energy sources especially water energy. As well as helping the realization of an Energy Independent Village based on Micro Hydro Power Plants (PLTMH) which is able to improve economic, social, educational and technology introduction aspects in rural areas of Ketapang Regency. This research activity consists of several stages, including: (1). Location Survey, (2). Calculation of Turbine Plan, (3) Economic Review, (4) Report Making. The results showed that, Siduk River Flow has an average available flow of 24 m³ / s and the height of water fall that can be optimized is 8 m, with the potential for electric power reaching 1.3 MW. The planned electrical power in the Siduk PLTMH is 500 kW (2 x 250 kW), with a design discharge (Qd) 2 x 4.75 m³ / s, with an effective fall height (Hn) of 7.6 m. Electricity production per year is 3,066,000 (kwh / year), with an investment of Rp. 16,000,000,000, investment period of 20 years. Pay Back Period (PBP) 3.9 Years, Rate of Return (ROR) 25.43%, Internal Rate of Return (IRR) 25.31%.

Abstract

The higher the growth rate, the greater the need for electrical energy required. In addition, the increase in population has resulted in many land functions becoming non-agricultural or agricultural from non-agricultural land. Therefore, the way to overcome the shortage of food security and environmentally friendly is the aquaponics system. Aquaponics cannot be separated from air circulation, where this water is the main need for both fish and plants. The water pump is an air propulsion driven by electrical energy. The problem is, because the air used for both plants and fish is the main ingredient, the water must flow and if the electricity goes out or other disturbances in electricity, the air flow process will stop, in addition to reducing electrical energy from PLN, one of the efforts that can be done This is done by utilizing alternative energy, namely using solar light energy into electrical energy or called PLTS. In the design of this PLTS using an off grid system. This off grid system is intended as a substitute for electricity when the electricity source from PLN is off or there is no PLN electricity at all. The design of this PLTS is done by calculating the required PLTS components, after that determining where to put the solar panels that are used. After knowing the specifications of the components, then you can do calculations for the Budget Plan (RAB) which will be recommended in the design of PLTS with this off grid system. The results of this PLTS design with an off grid system are using components in the form of solar panels, solar charge controllers, batteries and inverters. After calculating the load on aquaponics, in this design the components are obtained, namely 1 solar panel with a capacity of 150 Wp, 1 battery with a capacity of 70 Ah 12 Volt, 1 inverter with a capacity of 500 watts and 1 SCC capacity of 10 A. . The recommended fee is Rp. 3.500.000.00., for the PLTS.

Abstract

Baggage handling has an important role in maintaining the comfort of passengerstraveling by airplane and processing the baggage until it can be transported together on the same plane with the passengers. But so far, passengers don't knowhow to process the luggage that has been handed over at the check-in counter tothe plane's baggage. But so far, passengers don't know how to process luggage from planes to passengers. Along with the growth of flight movements (passengers and aircraft), currently the technology applied to handling passenger baggage has developed rapidly.The current conveyor system runs continuously, whether thereare goods or not, to turn off the conveyor still uses human/operator power. If theoperator is careless/less orderly can lead to human error so that the increased useof electricity. One of the services that use conveyor systems such that Rahadi Oesman Airport Ketapang. Of these problems, the system is designed to automatically on the conveyor. This design has been in system tools automatically on a conveyor that can be turn on without pressing the start button if the storage detected the presence of goods and conveyor can die without pressingthe stop button when the trunk does not detect the presence of goods that are processed by the Proximity Sensor Retroreflecting. The system automaticallyon the conveyor can be applied in Rahadi Oesman airport Ketapang to facilitate the performance of technicians and electricity saving.

Abstract

The increasing demand for electrical energy, the performance of the equipment in the power plant also increases. Transformer is a tool that feels the impact, namely the increasing temperature of the conductor inside the transformer. To find out the indications of failure in the transformer, we can test one type of insulation on the transformer, namely transformer oil, by testing the Dissolved Gass Analysis and testing the breakdown voltage (Breakdown Voltage). After testing the DGA, the TDCG results are analyzed, whether they are in accordance with the IEEE 1991 Standard. And the Breakdown Voltage is in accordance with the IEC 60156 Standard (SPLN). Test results in November 2021, the TDCG value is in condition 2 referring to the IEEE 1991 standard, where in conditions This requires vigilance and must determine the allowable loading. And after testing the breakdown voltage of the transformer oil, it is known that the breakdown voltage condition is ≤ 30 kV, if it is adjusted to IEC 60156 standards, the breakdown voltage value of the oil starts to be LOW/NOT GOOD. When the results of the Dissolved Gas Analysis and Break Down Voltage tests are not in accordance with the Standards, it results in a decrease in insulation resistance which causes not optimal power to be supplied to customers. Therefore, to maintain the performance or life time of the transformer itself, maintenance is needed. Treating oil is an effort that must be made to maintain the insulation resistance according to the permitted standards and the transformer can operate optimally.
