Perumahan Giripalma mempunyai sumur air yang dikelola sendiri oleh warga Perumahan. Penggunaan air dari sumur ini berbayar atau dengan kata lain warga Perumahan berlanggan. Warga berlangganan dimaksudkan agar pemakaian air tidak boros, dengan demikian diharapkan agar sumur tidak cepat habis airnya. Air dari sumur ini dinaikan ke tandon dengan menggunakan motor pompa listrik tiga fasa 380V. Sampai saat ini motor pompa dihidupkan dan dimatikan dengan cara manual, yaitu apabila apabila air di tandon sudah habis maka pompa dihidupkan, sampai tandon air penuh. Ada petugas sendiri yang menghidupkan dan yang mematikan pompa. Kelemahan dari cara manual ini, petugas sering bolak-balik untuk melihat apakah tandon sudah penuh atau belum, karena kalau tandon ditunggu sampai penuh maka butuh waktu lama, padahal dengan waktu yang lama ini petugas bisa mengerjakan pekerjaan yang lain.Untuk memudahkan dan meringkankan pekerjaan petugan maka kami membuat kontrol pompa air ini secara otomatis, yaitu apabila tandon kosong maka otomatis pompa bekerja, dan apabila tandon penuh pompa maka berhenti. Selanjutnya untuk memantau kontrol pompa air ini tidak dipercayakan kepada petugas lagi tetapi dipercayakan kepada Karang Taruna Perumahan Giripalma, agar Karang Taruna bertanggungjawab terhadap lingkungan hidupnya, dan untuk kerampilan mereka di masa mendatang.

he electric power system is a system consisting of several parts, namely generating units, transmission units, distributionunits, and load units that are interconnected and work together to serve the electricity needs of customers according to their needs. In theprocess itself, electrical energy is distributed from the generator through the transmission network until it is received by consumers orcustomers so that in this case a related plan is needed. Planning here aims to get an optimal service flexibility so that it is able to quicklyanticipate the growth of electrical energy and how dense the load that must be served. So that the planning of the electricity distributionnetwork system must pay attention to the load conditions in the field, this is intended so that the planned distribution network system can stillwork well for the next few years. The data collection method used is in the form of field observations which aim to determine field conditionsand obtain load data that will be planned. The results of research conducted at The Grand Kenjeran Surabaya housing show that there are76 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 powerof 5500 VA for each housing unit along with Public Road Planning in residential areas. Taking into account field conditions, ground cablesare used as a distribution network system which includes SKTM and SKTR. The total power obtained is 435,107.5 VA and is served by 3units of distribution transformer using Pole Transformer Substation, 3 PHB-TR, 12 Main PHB, and 3 Branch PHB. The magnitude of thepossible 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).

At PT. PLN (Persero) ULP Batu, Pujon feeder is one of the 9 feeders in the distribution system that supplies severalareas in PT. PLN (Persero) ULP Batu. At the Pujon feeder, the number of disturbances that occurred from January to November 2021occurred twenty-two times, with details of eighteen temporary disturbances and four permanent disturbances. The number of disturbancesthat often occur can affect the feeder who is working normally. This can cause voltage drops and power losses, causing the flow of electricpower to be less than optimal and detrimental to customers or consumers. Because it requires maneuvering so that the disturbance does notspread to all feeders and cause one feeder to experience a blackout. Based on the problems that occur, maneuver analysis is needed toreduce the impact of disturbances on the Pujon feeder and to maintain the reliability value of the distribution system at PT. PLN (Persero)ULP BATU.

The Tlogosari feeder was disturbed 20 times so that the reliability of system wasn’t said to be good. The purpose of this research was to make efforts to increase reliability and reduce ENS by maneuvering the network and adding CO Branch. Hoped that after these efforts the reliability level of Tlogosari Feeder will be better and ENS will be as minimal as possible. The network maneuver is carried out by delegating part of Tlogosari Feeder load when it experiences a disturbance to the nearest feeders on the condition that the total load current after the maneuver doesn’t exceed the current setting and conductor ampacity. The addition of CO Branch is based on fault data to localize fault points to reduce transformer outages. After performing network maneuvers and adding CO Branch in the sub-networks, it was found that the SAIDI and SAIFI values were improved and the ENS was reduced. Network maneuvering and addition of CO Branch are quite effective in implementing the Tlogosari Feeder.

In this era, Indonesia's industry is rapidly developing and relies heavily on electrical components, especially in the Agro-Industry Machine Workshop of CV. Karya Brawijaya. CV. Karya Brawijaya is an industry that produces agro-industrial machinery. In the planning of external protection systems, the commonly used methods are conventional lightning rods and electrostatic methods. Therefore, to further examine the situation, observations conducted in the industry revealed the absence of a lightning protection system. Hence, the author aims to plan and compare the two types of lightning protection systems, namely conventional (Franklin) and electrostatic (E.F. Lightning Protection System), in terms of protection, technical aspects, economy, advantages, and disadvantages. The research and observations were conducted in the CV. Karya Brawijaya building area, using data collection techniques such as direct observation, interviews, and literature studies. This process yielded building layout data (height, width, and length) and data on thunderstorm days in 2019 (IKL 243). These data were then used to calculate the parameters for lightning protection system installation planning according to the standards set by SNI 07015-2004 and PUIPP. The results of the conventional method (Franklin) planning, with air terminations using rolling spheres, showed that 9 finials were installed, allowing the building to withstand currents up to 160.06 kA. On the other hand, the electrostatic method (E.F. Lightning Protection System) planning resulted in the installation of 1 finial, enabling the building to withstand currents up to 23.737 kA. If the current exceeds these values, the lightning protection system will capture the lightning strike.
