Abstract

The need for electricity is one of the important things in the advancement of technology and human civilization in all respects. So it is necessary to regulate the use of electrical energy properly. Thus, it is very important for us to regulate the use of electrical energy in terms of power usage by electrical loads. One way is by saving electrical energy. One way to save electrical energy is an energy audit. The audit report is the result of the audit plan which will be processed and analyzed further in energy management (electrical energy regulation). From the results of the energy audit, energy flows will be known which will provide an overview of energy use, so that a strategic plan can be prepared to control energy use better and of course be more energy and cost efficient. One aspect of an energy audit is an audit of lighting energy (lighting in an area), so it is very important for us to control the use of electrical energy loads, in this research the kit only audits electrical energy, from the lighting energy of the Muara Batu sub-district office, North Aceh, so that the use of electrical energy becomes economical. Efficient use of energy can be a solution that will be very profitable in efforts to increase comfort. When an office is able to carry out energy efficiency, it means that the office has benefited from savings in energy consumption costs in a certain period, then from these results there are funds available that can be converted for other needs such as adding facilities or replacing equipment, which will indirectly increase employee comfort or the office.

Abstract

Technological developments have brought a revolution in the smart home concept, with smart rooms becoming the main focus to increase comfort, efficiency and security. This article explores the concept of a Programmable Logic Controller (PLC) based smart room with Function Block Diagram (FBD) programming. PLCs, which were originally used in industry, were introduced into the smart home environment as a central brain capable of managing and controlling electronic devices. FBD programming, with its visual approach, provides an intuitive programming solution by using function blocks to represent control logic. Through the use of FBD-based PLCs, smart rooms can be effectively automated, including lighting, temperature and security aspects. The advantages of this method include an easy-to-understand programming interface and the ability to design control logic without requiring a deep understanding of programming languages. The research results show that FBD-based PLCs provide an efficient and effective solution to improve the function of smart rooms. This implementation can provide significant benefits in terms of energy management, occupant comfort and home security. Thus, the PLC-based smart room concept with FBD programming marks a step forward in realizing a smart home that is responsive, connected, and can be adapted to the needs of residents.

Abstract

Load variations found in PT PLN Persero customers, such as resistive, inductive, or capacitive loads, can potentially affect the error rate in kWh meter readings. To determine the error rate of kWh meter readings, it is necessary to compare the reading data from each kWh meter with the measurement data from a 6-in-1 multimeter display. This involves comparing the prepaid digital kWh meter, the postpaid semi-digital kWh meter, and the postpaid analog kWh meter, all assembled in series. Based on the test results, the average reading error rate for resistive loads was found to be 0,11% for the prepaid digital kWh meter, 6,91% for the postpaid semi-digital kWh meter, and 0,36% for the postpaid analog kWh meter. For inductive loads, the average reading error rate was 0,36% for the prepaid digital kWh meter, 7,00% for the postpaid semi-digital kWh meter, and 0,27% for the postpaid analog kWh meter. For capacitive loads, the average reading error rate was 0,09% for the prepaid digital kWh meter, 7,52% for the postpaid semi-digital kWh meter, and 0,62% for the postpaid analog kWh meter. This research is important for the electricity supply industry because the accuracy of electrical energy measurement is a key factor in maintaining operational efficiency and improving tariff fairness for customers.

Abstract

The penetration of biogas power plants into the distribution network can affect power system stability, particularly in the 20 kV distribution network in Tanjung Pura. This study aims to analyze the impact of biogas power plant penetration on voltage stability and power flow dynamics in the distribution network. A simulation-based approach using ETAP software is employed to evaluate different penetration levels, ranging from low to high. The results indicate that biogas power plant (PLTBg) penetration increases system voltage from the existing 17.92 kV (89.63%) to 18.34 kV (91.73%) at 25% penetration and reaches 19.50 kV (97.50%) at 100% penetration. Under a load increase of 25% to 75%, the voltage without penetration ranges from 17.56 kV (87.80%) to 17.05 kV (85.30%). With gradual penetration, the voltage rises to 17.99 kV (90%)–17.28 kV (86.40%) at 25% penetration and reaches 19.15 kV (95.40%)–18.47 kV (92.30%) at 75% penetration. Additionally, higher PLTBg penetration reduces active power losses but increases reactive power losses, which could compromise network stability if not properly compensated. The optimal condition is observed at 50% loading with 75% penetration, where voltage remains within normal limits while both active and reactive power losses are more stable compared to other scenarios.
