Economic dispatch aims to control the variables of the power system so that the power plants can generate maximally based on load demand according to the characteristics of each plant and with cheaper production costs. In this study, economic dispatch is applied to thermal power plants with the integration of Wind Power Plants (PLTB) in Sulselrabar 150kV power system using the Novel Bat Algorithm (NBA) optimization method, considering voltage stability. The generation cost that can be reduced using the NBA method is IDR 12,583,781 per hour compared to the results of the existing system. With the integration of 100% of the PLTB capacity, the NBA method still provides cheaper economic dispatch results. Using the NBA method, the generation cost can be reduced by IDR 29,854,367 compared to the results of the existing system. After the integration of 100% of the PLTB capacity, the power losses obtained are smaller than before the integration of the PLTB. The system bus voltage conditions before and after the integration of the PLTB are also in good condition as they are within the voltage regulation limits set by PLN, which are +5% and -10%

Motor induksi tiga fasa terhambat oleh kesulitan yang melekat dalam pengaturan kecepatan. Hal ini disebabkan oleh fakta bahwa motor ini berputar dengan kecepatan konstan. Kontrol Variable Frekuensi Drive (VFD), yang terhubung secara fisik ke motor, dapat digunakan untuk mengatur frekuensi masuk motor induksi tiga fasa. Untuk mengatur kecepatan motor, tujuan penelitian ini adalah untuk mengetahui pengaruh memvariasikan frekuensi sumber terhadap arus motor induksi tiga fasa yang beroperasi pada kondisi beban dan tegangan sumber konstan. Pada pengujian terdapat 3 skenario pengujian yaitu (1) Pengujian VFD dengan frekuensi yang bervariatif, (2) Pengujian VFD dengan beban konstan, (3) Pengujian motor induksi tanpa menggunakan VFD. Hasil penelitian yang diperoleh (1) Perubahan frekuensi berbanding lurus dengan perubahan kecepatan motor, (2) Arus pada kumparan motor cenderung stabil, (3) Kumparan motor cenderung mengalami kenaikan. Maka dari itu arus cenderung stabil 2,3 - 2,4 (A) terhadap kumparan motor.

Abstract— One strategy to improve the voltage profile is by placing optimal capacitors in the right locations in the distribution system. Installation of capacitors in distribution systems is carried out for several purposes such as: improving voltage regulation, improving power factor, reactive power compensation, increasing line capacity and reducing losses. The tolerance limit for permissible stress values is 0.95 to 1.05 per unit. In this research, power quality improvements will be carried out using capacitor banks at PT Semen Bosowa Maros. The repair process is simulated using the Genetic Algorithm (GA) method. This method carries out several simulations, namely the power flow before and after installation of the capacitor bank, optimization of capacitor placement which is carried out three times with different bus candidates, to determine the location, number of capacitor capacities, and economic analysis. The selection of buses that experience voltage drops has been produced to improve the quality and voltage stability of the electrical system at PT Semen Bosowa Maros which provides a solution considering economic factors after installing the capacitor bank.

Pada penelitian ini bertujuan untuk merancang prototype system buka dan tutup pintu secara otomatis. Berdasarkan kasus pencurian yang ada, 60 % kasus pencurian dalam rumah karena pelaku merusak system pnguncian yang ada dalam rumah. dan yang mengejutkan 30% kasus pencurian diakibatkan karena pemiliki rumah lupa menngunci pintu sebelum keluar rumah. maka dari itu dengan memanfaatkan teknologi yang ada. Sistem penguncian rumah otomatis akan memberikan efek keamanan bagi pemilik rumah untuk bisa tetap waspada dalam beberapa kasus pencurian. Dalam penelitian ini, system penguncian rumah yang dirancang menggunakan sensor PIR yang akan mengirimkan signal ke mikrokontroller. Sehingga, actuator akan menggerakkan pintu dengan menutup dengan sndirinya. Dari hasil rancangan diperoleh system dapat mendeteksi suatu gerak dan proses perancangan dan pemrograman kami telah menentukan waktu dengan 5 detik dan jarak 1,5 Meter pada sensor PIR. Pembuatan pintu otomatis menggunakan sensor gerak lebih mudah di gunakan dan sensor PIR memiliki sensitivitas tinggi dalam membaca objek dan menggerakkan pintu melalui motor servo.

The Garassik Micro-Hydro Power Plant in Panassang Village, Enrekang Regency, with an installed capacity of 3.7 kW, experiences an energy deficit due to the community's electricity demand of 390.74 kWh per day. Despite its efficient operation, the plant generates a maximum of only 88.8 kWh per day, underscoring the need for capacity enhancement. This study explores the potential of utilizing turbine wastewater as an energy source by designing a Multi Powerhouse (MPH) Micro-Hydro Power Plant to optimize water energy usage. The proposed MPH system evaluates water energy potential, determines optimal powerhouse placements for effective head height, and calculates total power output. Unlike the single-powerhouse model, the MPH system addresses water flow limitations, particularly during periods of reduced flow, significantly improving total power output to 160.235 kW, a 171% increase. Key advantages of the MPH model include better utilization of turbine wastewater, enhanced operational flexibility, and improved water energy efficiency. Using a descriptive quantitative research method, this study begins with a location survey to collect turbine wastewater characteristics, followed by mathematical modeling for analysis. Results reveal output flow rates of 0.189 m³/s, 0.187 m³/s, and 0.185 m³/s across three powerhouses, with effective head heights of 24.782 m, 29.725 m, and 34.729 m, respectively. The system uses Crossflow turbines, ideal for medium heads and moderate flow rates. Economic analysis indicates an NPV of IDR 2.400.000.000,- an IRR of 14%, and a BCR of 2.5, with a payback period of 5.45 years, making the project financially viable and sustainable.

Electricity is a crucial infrastructure supporting economic and social development, thus requiring reliable supply planning. In Soppeng Regency, historical data from 2019–2023 show population growth from 226,992 to 240,955 people and GRDP increase from 10,938 to 14,909 billion rupiah, driving higher electricity demand. Customer numbers rose in the household sector from 29,438 to 34,376 and in industry from 33 to 58, with similar upward trends in connected load and energy use. This study addresses the challenge of accurate forecasting by applying Multiple Linear Regression (MLR) optimized with Genetic Algorithm (GA). Forecasting results up to 2028 predict household customers reaching 40,449 and industrial customers 89, while connected load grows from 35.7 to 34.0 million VA in households and from 8.6 to 17.4 million VA in industry. Electricity consumption is projected to exceed 41.8 million kWh in households and 13.5 million kWh in industry by 2028. Model evaluation using Mean Absolute Percentage Error (MAPE) confirms reliable accuracy, making the MLR–GA approach effective for future capacity planning.
