Abstract

Pengembangan Energi Baru dan Terbarukan (EBT) merupakan salah satu pilar penting dalam mendukung transisi energi nasional yang berkelanjutan. Dalam rangka mendukung hal tersebut, diperlukan peningkatan literasi dan keterampilan generasi muda, khususnya siswa Sekolah Menengah Kejuruan (SMK), yang memiliki potensi besar sebagai calon tenaga terampil di bidang energi. Program pengabdian masyarakat ini bertujuan membangun kolaborasi strategis dengan SMKN 2 Gerung dalam bentuk pelatihan, pendampingan, dan penguatan jejaring mitra. Hasil kegiatan ini didapatkan kesepahaman kegiatan yang disepakati meliputi penyuluhan mengenai energi terbarukan, pelatihan teknis sederhana (seperti desain pembelajaran berbasis PLTS dan pelatihan pengukuran potensi energi terbarukan), serta pendampingan pengembangan proyek berbasis EBT oleh siswa. Serta terjalinnya hubungan kemitraan berkelanjutan antara pihak sekolah dan tim pengabdi. Program ini diharapkan menjadi model kolaboratif yang dapat direplikasi di sekolah-sekolah kejuruan lainnya.

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

Integrasi Renewable Energy (RE) pada sistem tenaga listrik memberikan dampak terhadap karakteristik operasi jaringan, khususnya pada profil tegangan dan rugi daya. Meskipun RE mampu meningkatkan efisiensi sistem melalui suplai daya lokal, integrasi yang tidak terkontrol dapat menyebabkan ketidakstabilan tegangan, frekuensi. Penempatan RE pada titik tertentu dalam jaringan dapat memodifikasi pola dan arah aliran daya pada saluran transmisi. Penelitian ini bertujuan untuk menganalisis pengaruh integrasi RE terhadap profil tegangan dan rugi daya sistem tenaga listrik menggunakan PowerWorld Simulator. Sistem dimodelkan berdasarkan sistem uji standar IEEE 6-Bus dengan metode aliran daya Newton–Raphson. Simulasi dilakukan pada beberapa tingkat penetrasi RE yaitu 10%, 20%, 30%, dan 40% dari total beban sistem. Parameter yang dianalisis meliputi tegangan tiap bus serta total rugi daya aktif dan reaktif. Hasil simulasi menunjukkan bahwa integrasi RE meningkatkan tegangan minimum Bus 5 dari 0,9595 pu menjadi 1,0017 pu (mode PV) dan 0,9838 pu (mode PQ) pada penetrasi 120 MW. Rugi daya aktif menurun dari 13,42 MW menjadi 3,07 MW (PV) dan 3,81 MW (PQ), atau berkurang hingga 77,12% dan 71,61%. Namun, penetrasi tinggi menyebabkan tegangan mendekati batas nominal, sehingga diperlukan pengendalian daya reaktif. Secara kuantitatif, integrasi RE meningkatkan efisiensi dan margin kestabilan sistem secara signifikan.
