Abstract

High voltage direct current (HVDC) on transmission-link becomes a new prominent technology in recent years. The HVDC is applied to transmit amount of electrical energy from power plant to consumers. This method makes reactive power losses on transmission devices decrease significantly and stability level of generator increases. However, inverter HVDC transmission system can produce slow and high inverter transient current (ITC) response at high value of the up-ramp rate. This ITC phenomenon can be serious problem at starting time. So grey wolf algorithm is proposed to optimize input-output parameters of interval type-2 fuzzy control (IT2FC) in inverter-side HVDC. The proposed control performance’s is assessed by integral time squared error (ITSE) and peak overshoot (Mp) approaches. Simulation results show that small ITSE and low Mp of transient response are given by the IT2FC. The IT2FC is successful applied on inverter HVDC with better results compared to conventional PI control scheme.

Abstract

Occupational Safety and Health (OSH) is a fundamental aspect to ensure the security and continuity of academic activities, especially in technical laboratory environments that are highly prone to fire hazards. The Electrical Engineering Laboratory of the Faculty of Engineering, University of Mataram, is identified as a high-risk area due to the use of high-voltage electricity, electronic devices, and flammable materials. According to the fire triangle theory comprising fuel, heat, and oxygen fires can be prevented by eliminating one of these elements. A primary preventive effort in this context involves the use of fire extinguishers (APAR) and adequate training on their proper use. This study aims to evaluate the effectiveness of APAR training and awareness campaigns among active laboratory students. The training method applied an andragogical approach with the PASS technique (Pull, Aim, Squeeze, Sweep), accompanied by pre- and post-tests, simulated fire suppression, and participatory observation. Results showed a significant improvement in students’ understanding, with the average score increasing from 18.75% to 88.38% and the standard deviation decreasing from 9.22 to 6.16, indicating more uniform comprehension among participants. A paired t-test revealed a highly significant difference (p < 0.0001), and one-way ANOVA supported that the training had a measurable effect on all evaluated aspects. Beyond cognitive gains, students also demonstrated positive affective and psychomotor responses through active participation and practical suggestions, such as improving extinguisher placement and adding usage instructions. These findings indicate that the APAR training program not only enhances technical knowledge but also cultivates a culture of safety within the academic environment. It is recommended that such training be institutionalized as part of the laboratory's integrated OSH management system

Abstract

Jelantik Village faces environmental problems, especially waste generation from agricultural and household activities. The main livelihood of the people of Jelantik Village is livestock and farming. Because farming is the main livelihood, the people of Jelantik Village really need fertilizer for their agricultural needs, so it is very profitable if they are able to process organic waste into fertilizer. However, the people of Jelantik do not yet understand how to use waste to make fertilizer. This activity aims to help the people of Jelantik Village understand how to process waste, especially organic waste from agriculture, livestock, the tofu and tempeh industry, and household waste, into useful compost. The socialization was carried out using counselling methods and the direct practice of making compost using straw and an EM4 activator. The counselling was attended by at least 25 participants in a warm atmosphere and without any difficulties. The team has been able to share knowledge with the Jelantik Village community about the principles and stages of making proper compost fertilizer, so it is hoped that this can reduce the waste problem while producing quality compost fertilizer.

Abstract

The theory and application of external lightning protection systems for buildings are not included in the curriculum of the Electrical Engineering Department. Instead, this material is introduced to students through skill training outside regular class schedules, with a focus on components of external lightning protection systems such as finials, down conductors, and grounding. The obligation to install lightning protection systems on buildings is mandated by Law No. 28 of 2002 and Government Regulation No. 36 of 2005. Protection from lightning requires precise planning to be effective in safeguarding buildings. Analysis of lightning strike phenomena and their consequences can be conducted by applying theoretical principles, such as electric fields, magnetic fields, induction voltage, and various theorems related to lightning strike phenomena. Students are provided with an understanding of the concept of lightning strikes, the potential dangers, and the damage they can cause to buildings, living beings, and electronic equipment both inside and outside the building that is affected by lightning strikes. In this simulation, each group is given images of buildings with varying roof shapes and sizes. The buildings are equipped with external lightning protection systems, including the number and placement of finials on the roof, which are then simulated. The effectiveness of the finials placed in these locations is tested to analyze the extent of protection, to ensure that the building is protected from the dangers of lightning strikes.  A total of 40 students participated in this activity, divided into 8 groups. Five groups successfully simulated the installation of finials to achieve an effective level of protection against lightning strikes, while the remaining three groups could only determine the extent of the protection area without being able to plan the installation efficiently. This training provides a benefit by enhancing the knowledge and skills of the students. The students' enthusiasm is reflected in active discussions and question-and-answer sessions that contribute to problem-solving.

Abstract

Base Transceiver Station (BTS) towers are highly vulnerable to lightning strikes. A lightning strike is a moving electric charge that generates an electric field and a magnetic field, both of which are vector quantities, and induces voltage around the tower. The closer to the tower, the greater the values of the electric field, magnetic field, and induced voltage generated. A 49-meter highs tower in Mataram City is located 25 and 300 meters from residential areas and public facilities. The metabolism of living organisms, such as blood circulation, nerve function, heart rate, lung function, cell growth, and cell division, are also vector quantities. Exposure of living organisms to external electric fields exceeding the threshold of ≥10 kV/m can disrupt their metabolism. It is crucial to determine the magnitude and direction of the electric field vector caused by lightning strikes on BTS towers and how it affects living organisms around the tower. Observations are based on Coulomb's Law and its derivative theories on electric fields. The peak lightning current in tropical areas ranges from 10 to 100 kA, with a frequency of 200 kHz. The electric field intensity at distances of 25 and 300 meters is 58.30, 584.50, 4.86, and 48.71 kV/m, respectively. These results indicate that a distance of 25 meters from the tower is not safe from exposure to high electric field intensity values.

Abstract

Penelitian ini membahas analisis kinerja dua strategi modulasi pulsa lebar (PWM), yaitu Phase Opposition Disposition PWM (PODPWM) dan Alternate Phase Opposition Disposition PWM (APODPWM), dalam upaya meminimalkan Total Harmonic Distortion (THD) pada sistem inverter tiga fasa. Simulasi dilakukan menggunakan MATLAB/Simulink dengan parameter identik untuk kedua metode, mencakup tegangan DC sebesar 100 V, frekuensi pembawa 5 kHz, dan beban R–L. Analisis dilakukan terhadap bentuk gelombang keluaran, spektrum harmonisa, dan nilai THD berdasarkan hasil Fast Fourier Transform (FFT). Hasil menunjukkan bahwa metode APODPWM secara konsisten menghasilkan nilai THD yang lebih rendah dibandingkan PODPWM pada seluruh rentang indeks modulasi. Pada Ma=1.0, THD PODPWM mencapai 10%, sedangkan APODPWM hanya 8,3%. Setelah diterapkan filter LC (L = 5 mH, C = 22 μF), nilai THD menurun drastis menjadi 2,1% untuk PODPWM dan 1,2% untuk APODPWM, memenuhi batas standar IEEE Std. 519-2014. Selain itu, APODPWM menunjukkan bentuk gelombang keluaran yang lebih halus dan nilai RMS tegangan yang lebih tinggi, menandakan efisiensi konversi daya yang lebih baik. Hasil penelitian ini menegaskan bahwa strategi APODPWM lebih unggul dalam menghasilkan kualitas daya yang tinggi pada inverter tiga fasa dan dapat diimplementasikan secara efektif pada sistem penggerak motor, konversi energi terbarukan, serta kendaraan listrik.
