Abstract

Energy sustainability is crucial for mitigating climate change and reducing dependence on fossil fuels. This research evaluates a hybrid renewable energy system combining photovoltaic (PV) technology and wind turbines to meet the electricity demand of Wahid Hasyim University's Faculty of Engineering, totalling 555,000 VA. Using HOMER Pro software, the study identifies the optimal configuration based on technical, economic, and environmental aspects. The hybrid system integrating PV, wind turbines, batteries, and converters achieves the lowest Net Present Cost (NPC) of $214,877 and a Levelized Cost of Energy (LCOE) of $0.0185/kWh, outperforming grid-only systems. Environmentally, the system significantly reduces carbon dioxide (CO2) emissions, from 559,226 kg/yr in conventional systems to 62,452 kg/yr. Solar energy contributes 56% of electricity generation, leveraging stable solar radiation of 4.28–5.54 kWh/m²/day. Additionally, an annual surplus of 156,350 kWh can be sold back to the grid, enhancing operational efficiency. This study demonstrates that hybrid renewable energy systems deliver long-term cost efficiency and significantly mitigate climate impacts. It provides a sustainable energy model for campuses in Indonesia and worldwide, particularly in regions with abundant solar resources.

Abstract

Separator baterai yang terbuat dari keramik zeolit telah dilakukan. Separator ini dimungkinkan menjadikan baterai yang stabil dan tahan lama. Penelitian ini bertujuan untuk menganalisis tegangan yang dihasilkan dari aki yang separatornya diganti dengan keramik zeolit alam. Penelitian ini menggunakan metode eksperimental. Teknik analisis data menggunakan analisis kuantitatif dan kualitatif. Hasil penelitian menunjukkan proses persiapan bahan dengan pengayakan serbuk zeolit dan tepung jagung dengan ayakan mesh 30. Serbuk zeolit ditambahkan 2, 5 dan 8 % berat tepung jagung. Bahan serbuk zeolit-tepung jagung dicetak berbentuk prisma segi empat dengan tekanan 15 MPa. Green keramik dibakar dengan furnace selama 4 jam dengan suhu 900 ⁰C. Keramik berpori di assembling ke baterai bersama anoda katoda kemudian dirangkai secara seri. Cairan  sebesar 10 ml digunakan untuk mengisi rongga keramik berpori tersebut. Hasil pengujian tegangan listrik menunjukkan semakin tinggi penambahan tepung jagung semakin rendah voltase yang dihasilkan. Berdasarkan pengujian secara visual dan mikro di dapat bahwa semakin banyak persentase campuran tepung jagungnya maka semakin banyak pula pori yang terdapat pada keramik serta mengurangi kerapatan pada keramik. Implikasi penelitian ini diharapkan separator keramik zeolit alam dapat dipakai pada baterai aki dengan peningkatan sifat sifik dan ionik konduktifitas.
