Abstract

Indonesia's rapid population growth and industrial expansion have significantly increased electricity consumption over the past decades. However, the COVID-19 pandemic has had a profound impact on the energy sector, causing a sharp decline in electricity demand. This disruption not only altered electricity consumption patterns but also forced a downward revision of the national electricity consumption target by approximately 10% compared to the government's initial projection. Understanding these shifts is crucial for ensuring sustainable energy planning and policy development. This study aims to analyze the impact of the pandemic on electricity consumption and forecast electricity demand in Indonesia from 2021 to 2045 using the Autoregressive Integrated Moving Average (ARIMA) method. Two forecasting scenarios are examined: one incorporating data from 2020 and another excluding it. The results indicate that excluding the 2020 data yields a more realistic projection, estimating electricity consumption to reach 610,807.8 GWh by 2045. The predictive performance of the ARIMA model is validated with statistical metrics, achieving an RMSE of 2,807.25, MAE of 1,481.25, and MAPE of 5.47%, with an overall accuracy of approximately 94.53%. These findings demonstrate that the ARIMA method is a robust and reliable tool for long-term electricity demand forecasting in Indonesia. The insights gained from this study provide valuable guidance for policymakers and energy planners in designing resilient and adaptive strategies to accommodate future electricity demand while considering the impacts of unprecedented disruptions such as pandemics.

Abstract

Program pengabdian Masyarakat ini bertujuan untuk meningkatkan wawasan dan pemahaman siswa SMKN 6 Bandung yang mengambil jurusan elektronika tentang Energi Baru Terbarukan (EBT) melalui pemahaman terpadu. Aktivitas dilaksanakan dengan metode penyuluhan interaktif yang mencakup presentasi visual, dan demonstrasi alat Pembangkit Listrik Tenaga Surya portable, dan sesi diskusi untuk memaksimalkan keterlibatan para peserta. Peningkatan pemahaman siswa dikaji melalui pre-test dan post-test, sementara perubahan sikap dan motivasi diukur lewat wawancara mendalam. Hasilnya menunjukkan peningkatan rata-rata skor pemahaman sebesar 10,64 poin, dari 50,21 di pre-test menjadi 60,85 di post-test serta antusiatisme siswa mengalami peningkatan setelah demonstrasi alat yang menunjukkan pengubahan energi matahari menjadi Listrik. Program ini juga menghasilkan materi edukatif dalam bentuk modul dan video dokumentasi yang dipublikasikan di YouTube. Kegiatan ini diharapkan dapat mendorong siswa berperan dalam mendukung peralihan energi berkelanjutan di sekolah ataupun lingkungan sekitar.
