Renewable energy is a real source of energy that is easy and cheap to use, especially water, therefore it is often used for electrical energy generation systems by utilizing river or waterfall flows. One form of utilization is the Picohydro Power Plant (the smallestscale power plant). Where there is energy potential in an area but has not been utilized optimally, by utilizing the flow of waterfalls in Watu Lumpang Pacet Waterfall Tourism Mojokerto Regency using turbines as a drive and generator as a generator. However, because it is generated in the form of Direct Current (DC) electricity, it takes an inverter as a converter that can convert DC voltage to Alternating Current (AC). So it can be used to supply loads that mostly require AC electricity to operate.

This research is focused to help peoples in remote areas who do not have electricity supply from PLN, but have sources of water flow in rivers. The main objective of this research is to create a picohydro hydroelectric power plant with a floating turbine to utilize the kinetic energy of river water flow in areas that have not been supplied with PLN electricity. The flow of water in the river will rotate the turbine, which in the end the rotational power is channeled through a pulley and belt system, which eventually turns an alternator. The alternator used is a three-phase AC alternator. Then the AC current will be rectified by the bridge rectifier to then be used to charge the battery and go to the load. In addition, in this study, the ability of the pico-hydro system to supply electrical energy will be tested to be able to run 12 V DC electrical loads and charge 12 V batteries.

An audit energy needs to be carried out because the value of Energy Consumption Intensity in 2020 is 251 kWh / m2 / year and in 2021 it is 221 kWh / m2 / year and the value of Specific Energy Consumption in 2020 is 0.26 GJ / Ton and in 2021 is 0.29 GJ/Ton. The energy audit method used is to calculate the value of Energy Consumption Intensity and Specific Energy Consumption. The savings opportunities made are on the air conditioning system, lighting system, and electric motor load. From the results of the analysis and calculation of savings in the air conditioning system, savings of 50.1% or 67.70 kWatt were obtained using a psychrometric diagram to determine the cooling system according to the needs of the room, then for the lighting system, savings of 21.9% or 6 kWatt by replacing the installed lighting system with energy-saving lamps, then the load of the electric motor is using capacitor to improve the power factor value which was originally 0.77 to 0.85 with the aim that the motor speed does not change which will result in the precision of the production obtained savings in the use of apparent power of 7.13% or 126.52 kVA. The total recommended power saving obtained from the calculation results is 73.7 kWatt. So based on the calculation of the energy audit that has been done, it can reduce production costs and energy use efficiency

One of the causes of the reduced life of the transformer is due to loading. From the eleven transformers, it can be seen that there are different loading variations, it is expected that the transformer life will remain at normal age. IEC 60354-1, 1991 stipulates the normal life of the transformer is 20.55 years. The research method used is to perform calculations using the long-time method and 24-hour daily data by calculating the loading at the time of LWBP and WBP on a 20 kV distribution transformer. Analysis of the calculation results revealed that the normal condition of the transformer P1385 (68.66 %) winding temperature at LWBP 67.47°C and when WBP 69.45°C compared to transformer P0032 with overload conditions (120.91%) winding temperature when LWBP 60, 88°C and at WBP 119.51°C. From the data on the lowest loading on the eleven transformers, namely transformer P0527 (41.69%) it is obtained that the estimated real aging age is 0.125 and the estimated age of the P0527 transformer is >20 years. Compared to transformer P0032 (120.91%), the estimated real aging age is 12,0003 p-u and the estimated age is less than 20 years or 9.5 years. Loading above 100% on the transformer based on the standard IEC 60354-1, 1991 if it takes place continuously will cause heating of the transformer windings which can cause the shrinkage process in the life of the transformer to be faster.

Transformers MA164 (250 kVA) and MA267 (250 kVA) have experienced overload (LoadMA164 = 102% and LoadMA267 = 111%) based on the loading standardization, namely SE DIR PT. PLN (Persero) No.0017/2014 (≤ 80%). The MA164 and MA267 transformers also have the farthest customer end voltages of 187 V (ΔVMA164 = 23%) and 189 V (ΔVMA267 = 22%) which do not comply with SPLN standard No. 1 Th. 1995 (+5% and -10%). An effective solution is to install an insert transformer because MA164 and MA267 cannot be uprated and cannot be broken by the JTR load. For planning the installation of the insert transformer it is necessary to carry out load forecasting, determination of the capacity of the insert transformer, division of the line of the farthest customer parts, determination of the location and selection of distribution substation accessories.The MA164 insert transformer (160 kVA) is installed at a distance of 416 m from the MA164 Transformer with a loading of 47%, while the MA267 insert transformer (200 kVA) is installed at a distance of 255 m from the MA164 Transformer with a loading of 47%. After installation the insert transformer MA164 transformer has a load of 77% and a end voltage of 211.9 V (ΔVMA164 = 9%), while the MA267 Transformer has a loading of 62% and an end voltage of 212.7 V (ΔVMA267 = 8%). With the appropriate conditions, the transformer can function properly and the customer's electrical equipment can function normally.

Planning here aims to get an optimal service flexibility so that it is able to quickly anticipate the growth of electrical energy and how dense the load that must be served. So that the planning of the electricity distribution network system must pay attention to the load conditions in the field, this is intended so that the planned distribution network system can still work well for the next few years. The data collection method used is in the form of field observations which aim to determine field conditions and obtain load data that will be planned. The results of research conducted at The Grand Kenjeran Surabaya housing show that there are 76 housing units to be built in this housing. The 76 housing units will be divided into 4 blocks D, E, F, G and are planned with an initial power of 5500 VA for each housing unit along with Public Road Planning in residential areas. Taking into account field conditions, ground cables are used as a distribution network system which includes SKTM and SKTR. The total power obtained is 435,107.5 VA and is served by 3 units of distribution transformer using Pole Transformer Substation, 3 PHB-TR, 12 Main PHB, and 3 Branch PHB. The magnitude of the possible voltage drop is around 0.97% for medium voltage, 0.3% - 0.92% for Main PHB group, 0.7% - 1.54% for Branch PHB group.

The increasing use of energy, in line with the development of the economy and industry, it is also necessary to realize the importanceof saving energy on the consumption side. Energy conservation is an increase in the efficiency of energy used or energy saving processes.This process includes an energy audit, which is a method for calculating the energy consumption level of a building or buildings, the resultsof which will be compared with existing standards to then look for solutions to save energy consumption if the energy consumption levelexceeds existing standards. The method used for research in this final project uses a walking audit by collecting data based on current,voltage, and power measurements. The data will be used to determine the analysis of the consumption of electrical energy used in the PT.Telkom Witel Unit Network and IS Operation Malang. Calculation of the IKE value (Energy Consumption Intensity) of the Malang City STObuilding for the results from the account data, the results are 479.14 kWh/m²/year. As for the IKE value from the measurement, the result is443.5 kWh/m²/Year 2, the value of the IKE is very inefficient from the standard compared to the ASEAN USAID standard in 1987, becausethe total power per year is not proportional to the existing building area. The lighting strength value after the recommendation is according tothe standard by replacing the lamp with a large lumen value, while in the cooling system the calculation of the BTUH requirement for eachroom is compared to the BTU AC (Air conditioner).
