Abstract

The three-phase induction motor stands as the predominant choice in industrial applications due to its numerous benefits. To optimize its performance, maintaining the integrity of the motor's power supply is essential. A significant factor influencing power quality is the load applied to the motor. This research focuses on analyzing and calculating the power consumption of a three-phase induction motor under varying control valve opening conditions, ranging from 10% to 100%. The motor under study operates as a pump driver, facilitating the transfer of sweet water in the fatty acid production facility at PT Unilever Oleochemical Indonesia. Key parameters examined include variations in current, power factor, and input power. Findings indicate that when the valve opening varies from 10% to 100%, the motor’s power output reaches up to 106% of its rated capacity at full valve opening. Conversely, at the minimum valve opening, the motor’s efficiency drops to 67.9% relative to its nominal power.

Abstract

Penelitian ini menganalisis karakteristik output Ground Power Unit (GPU) yang digunakan untuk menyuplai listrik pesawat ATR 72-600, khususnya pada parameter tegangan, arus, dan daya arus searah (DC). Studi ini dilatarbelakangi oleh peran krusial bandar udara dalam mobilitas dan ekonomi, serta esensialnya GPU untuk operasional pesawat di darat. Ketergantungan ATR 72-600 pada sumber daya eksternal, karena ketiadaannya Auxiliary Power Unit (APU), menjadi justifikasi utama penelitian. Metode penelitian menerapkan pendekatan kuantitatif deskriptif melalui observasi lapangan komprehensif. Pengambilan data dilakukan langsung pada unit GPU tipe TLD GPU-4060 yang terintegrasi dengan pesawat ATR 72-600. Data primer dilengkapi wawancara teknis dan kajian literatur. Analisis data menggunakan perhitungan matematis untuk mengevaluasi kesesuaian output GPU terhadap spesifikasi teknis kelistrikan pesawat. Hasil analisis menunjukkan tegangan DC GPU berkisar 27,8-28,3 V DC, sesuai dengan spesifikasi pesawat (25-28 V DC). Arus teramati 100-150 A menghasilkan daya aktual 2,82–4,25 kW. Kapasitas daya kontinu GPU (28,5 kW) jauh melampaui konsumsi aktual pesawat, mengindikasikan operasional pada beban ringan dan minim risiko overload. Observasi lapangan tidak mengidentifikasi overvoltage atau undervoltage, menegaskan efektivitas Bus Power Control Unit (BPCU) pesawat dalam menjada stabilitas dan proteksi. Namun, kapabilitas GPU dalam menyediakan arus puncak tinggi (hingga 1.275 A untuk starting engine) krusial untuk mencegah disrupsi operasional.

Abstract

The increasing demand for stable and efficient electrical energy in telecommunication systems, particularly in IndiHome network infrastructure, requires a reliable energy management strategy. One of the key challenges faced is the presence of reactive power, which can reduce power factor efficiency and lead to higher energy losses. This study focuses on optimizing the energy management system using a 20 kV capacitor bank to improve power factor and reduce electrical losses in IndiHome network devices. The research involves the design, implementation, and analysis of a capacitor bank control system that responds dynamically to load variations. Through simulation and real-time testing, the system is evaluated based on its ability to maintain a high power factor, reduce energy consumption, and stabilize voltage levels. The results show that the optimized capacitor bank system can improve power factor to above 0.95 and reduce reactive power demand significantly, resulting in improved overall energy efficiency. This optimization not only reduces operational costs but also enhances the reliability and longevity of network equipment by minimizing voltage drops and harmonic disturbances. The study concludes that capacitor bank-based energy management systems are highly effective and essential for modern telecommunication infrastructure. Keyword : Capacitor Bank, Power Factor, Energy Management, Telecommunication, IndiHome, 20 kV, and Reactive Power

Abstract

Switched Reluctance Generators (SRGs) have attracted attention due to their robust construction, low cost, and high fault tolerance, suitable for extreme environments. However, SRGs suffer from torque ripple and acoustic noise due to the non-linear torque-excitation current relationship. Although SRG component optimization has been investigated, a gap exists in the analysis of the effect of stator excitation current on the drive torque in a single-phase "6/6" SRG design with external amplification. This study analyzes the impact of varying stator excitation current on the drive torque of a single-phase 6/6 SRG. The methodology includes design, finite element analysis (FEA), and testing of an initial drive torque prototype. Results show that increasing the stator coil supply voltage results in a greater magnetic force, which counteracts the mechanical torque on the rotor shaft. This understanding is crucial for optimizing torque performance, mitigating ripple, and improving SRG efficiency for future applications.

Abstract

To optimize the performance of sun tracking systems, adaptive and intelligent control techniques are required. One effective method for dealing with systems that have high uncertainty and non-linearity is fuzzy control. Fuzzy control has several advantages over conventional control methods, such as the ability to handle a variety of changing operating conditions and flexibility in application to various types of systems. By implementing fuzzy control, the sun tracking system can operate more efficiently, dynamically adjusting the tilt angle of the solar panels to obtain optimal sunlight intensity. In addition, the results of this research are expected to provide practical and applicable solutions for the development of renewable energy technology, especially in developing countries which have great potential for utilizing solar energy. Thus, this research has high urgency in the global and local context. . Optimizing the output power of solar panels through sun tracking systems with fuzzy control can be an important step towards a more sustainable, efficient and environmentally friendly energy system.

Abstract

Misuse of electricity by customers is the cause of non-technical losses. Non-technical losses result in losses to the state, where PLN as the party that distributes electricity unknowingly loses its main commodity without any reciprocity in the form of payment. The form of misuse that is most often found by customers is in the form of modifications to the Measuring and Limiting Equipment (APP). It is important to know the variations in One Phase APP Modifications made by customers because they can be used as a reference to increase the success of PLN's P2TL program to reduce non-technical losses. To find variations in these modifications, it is necessary to analyze each result of misuse by customers and also categorize them so that they are easy to classify. There are four types of abuse, each month the highest violations are Classes I and III, although the percentage decreases in the following months, down to 53% from the beginning of the month when it reached 80%, the losses received by PLN due to this violation are in the RP range. 291,166,223.00 Thus, analysis of this modification variation can improve the results of the P2TL Program in order to reduce losses to PLN.
