Abstract

This study investigates the dynamics of water level (TMA), electrical current, power, and battery voltage in a data loggerbased monitoring system designed for peatlands. Data collected from October 30 to December 4, 2024, highlight significant fluctuations influenced by environmental factors, load surges, and voltage disruptions. Scenario simulations, including changes in rainfall, sudden load increases, and voltage system disturbances, were performed to evaluate the system's operational efficiency and stability. The findings indicate that TMA is highly influenced by hydrological conditions, where a 50% reduction in rainfall significantly decreases TMA, impacting the stability of current and power. A 50% load surge drives the current and power close to the system's maximum capacity, while voltage disruptions lead to a 20% increase in current and a 20% reduction in power, revealing system imbalances. Energy efficiency remains stable under normal conditions (0.0022) but drops significantly during disruptions. The study underscores the need for integrating protective technologies, such as Automatic Voltage Regulators (AVR), Overcurrent Protection, and balanced load management, to mitigate risks and maintain system stability. Additionally, improved water management in peatlands contributes to stabilizing TMA and reducing environmental impacts on electrical parameters. This research highlights the importance of a holistic approach, combining technology, hydrological management, and data-driven simulations, for sustainable operations. The findings offer practical recommendations for system enhancement, risk mitigation, and the development of future energy monitoring tools. Opportunities for renewable energy integration are also explored to ensure long-term operational efficiency and environmental sustainability.

Abstract

Public speaking is an essential part of communication skills that is not easily mastered by everyone. Public speaking anxiety often prevents individuals from developing their public speaking skills. The negative impact can be seen from the physical and emotional health problems they experience. The solution lies in public speaking training that is fun and builds confidence in public speaking. Through seminar methods and public speaking practice, Community Service activities (PKM) are carried out. This approach helps in improving the public speaking skills of SMA Santo Yakobus students. This method is applied as the most effective form of public speaking training, in which discussions can be held with students, and ends with public speaking practice. Seminar at SMA Santo Yakobus showed an increase in participants' understanding of public speaking concepts as well as a significant increase in their understanding of goals, important factors, benchmarks for success, and preparation in public speaking after attending the seminar. Factors that influence communication effectiveness, such as understanding, satisfaction, influence on attitudes, and better relationships, are important in understanding public speaking success. ABSTRAK Public speaking merupakan bagian esensial dari kemampuan komunikasi yang tidak mudah dikuasai oleh semua orang. Kecemasan berbicara di depan umum seringkali menghambat individu untuk berkembang. Dampak negatifnya dapat terlihat dari gangguan kesehatan fisik dan emosional yang mereka alami. Solusinya terletak pada pelatihan public speaking yang menyenangkan dan membangun kepercayaan diri dalam berbicara di depan umum. Melalui metode seminar dan praktik public speaking, kegiatan Pengabdian Kepada Masyarakat (PKM) dilaksanakan. Pendekatan ini membantu dalam meningkatkan kemampuan public speaking siswa SMA Santo Yakobus.. Metode ini diaplikasikan sebagai bentuk yang paling efektif dalam pelatihan public speaking, di dalamnya dapat dilakukan diskusi dengan siswa, serta diakhiri dengan praktik public speaking. Seminar di SMA Santo Yakobus menunjukkan peningkatan pemahaman peserta terkait konsep-konsep public speaking serta peningkatan signifikan dalam pemahaman mereka tentang tujuan, faktor penting, tolok ukur keberhasilan, dan persiapan dalam public speaking setelah mengikuti seminar. Faktor-faktor yang mempengaruhi efektivitas komunikasi, seperti pemahaman, kepuasan, pengaruh pada sikap, dan hubungan yang lebih baik, menjadi penting dalam memahami keberhasilan public speaking
