Abstract

Battery Energy Storage Systems (BESS) have emerged as an innovative solution to enhance energy efficiency in commercial and industrial sectors, particularly through the implementation of peak shaving methods. This technology enables energy storage during periods of low demand and its utilization during peak demand, thereby reducing the load on the power grid. This study explores the integration of BESS in managing electrical loads to lower peak energy consumption while improving operational efficiency and power system stability. By utilizing daily load profile data and BESS parameters, a system is developed to regulate charging and discharging processes to achieve optimal energy balance. Simulation results indicate that BESS implementation can reduce peak loads by up to 50%, distribute energy more evenly throughout the day, and enhance the reliability and efficiency of the power grid. This technology also offers environmental benefits by reducing dependence on fossil fuel-based power plants and supporting the transition toward a more sustainable energy system.

Abstract

Artikel ini membahas ritual adat sebagai sumber belajar pada mata pelajaran Sosiologi di sekolah menengah. Kajian ini dilatarbelakangi oleh masih dominannya pembelajaran Sosiologi yang bersifat tekstual, abstrak, dan kurang terhubung dengan realitas sosial-budaya peserta didik. Melalui metode penelitian kepustakaan dengan pendekatan kualitatif deskriptif, artikel ini menelaah berbagai literatur tentang ritual adat, teori sosiologi, dan pendekatan pembelajaran kontekstual. Hasil kajian menunjukkan bahwa ritual adat memiliki potensi besar sebagai sumber belajar yang kaya nilai sosiologis, terutama dalam menjelaskan konsep solidaritas sosial, pengendalian sosial, stratifikasi sosial, perubahan sosial, dan pelestarian lingkungan. Ritual adat seperti Andingingi, Mappadendang, dan Rambu Solo memperlihatkan bahwa tradisi lokal bukan hanya warisan budaya, tetapi juga laboratorium sosial yang dapat dimanfaatkan untuk memperdalam pemahaman siswa terhadap fenomena masyarakat. Integrasi ritual adat dalam pembelajaran Sosiologi melalui pendekatan Contextual Teaching and Learning dapat meningkatkan pemahaman konseptual, kemampuan berpikir kritis, kepekaan sosial, serta penguatan karakter dan identitas budaya peserta didik. Dengan demikian, ritual adat relevan dijadikan sebagai sumber belajar yang kontekstual, bermakna, dan transformatif dalam pembelajaran Sosiologi.
