Abstract

Energi baru terbarukan berkembang pesat seiring dengan peningkatan pemberdayaan energi baru terbarukan. Sebagai salah satu upaya pemenuhan 100% elektrifikasi di Indonesia, berbagai jenis sumber daya baru terbarukan dikelola untuk menghasilkan listrik. Di Indonesia, potensi energi matahari sangat besar. Solar panel, ke depannya menjadi salah satu alat konversi energi yang banyak dikembangkan di Indonesia. Solar panel generasi ketiga yang sedang banyak dikembangkan adalah Dye-Sensitized Solar Cell (DSSC) di mana menggunakan pewarna alami sebagai dye. SMA Nurul Fikri, Depok dipilih karena pengembangan metode konstruktif pengalaman belajar yang diadopsi pada kurikulum mereka. Dari hasil pelatihan, 100% peserta mampu membuat DSSC sederhana. Selain itu, telah terjadi peningkatan pengetahuan yang ditunjukkan dengan peningkatan persentase jumlah siswa yang mengetahui proses DSSC berdasarkan hasil pre-test dan post-test.

Abstract

Stainless steel is widely utilized across industries due to its robust resistance to corrosion. Stainless Steel 201 (SS201), characterized by a lower nickel content compared to grade 304, is valued for its cost-effectiveness and strong mechanical properties. However, SS201 is more prone to pitting corrosion in aggressive environments than SS304. This research aims to enhance SS201’s resistance to pitting corrosion through surface treatment involving nitric acid. Cyclic voltammetry was conducted using nitric acid concentrations of 1, 2, and 3 M. The findings indicate that higher concentrations of nitric acid improved corrosion resistance, with 3 M resulting in a pitting depth of 23.667 μm. The application of citric acid contributed to enhanced resistance against pitting corrosion by fostering a chromium-rich surface.

Abstract

Perkembangan teknologi robotika memberikan peluang besar untuk memperkaya proses pembelajaran di tingkat sekolah menengah, khususnya dalam penguatan keterampilan abad ke-21. Namun, minimnya akses terhadap pengalaman praktik membuat siswa kesulitan memahami konsep robotika secara aplikatif. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mengenalkan konsep dasar robotika industri kepada siswa SMAK Tunas Bangsa Gading Serpong melalui praktik langsung dalam merakit dan menguji robot pengikut garis (line follower). Metode pelaksanaan kegiatan dibagi menjadi tiga tahap, yaitu persiapan, pelaksanaan, dan evaluasi, yang secara implisit mengikuti tahapan dalam model pengembangan instruksional ADDIE (Analysis, Design, Development, Implementation, Evaluation). Peserta dibimbing dalam perakitan tiga jenis robot: Analog A, Analog B, dan Digital. Evaluasi dilakukan melalui survei pre-test dan post-test, pengujian performa robot, serta kuesioner kepuasan peserta. Hasil menunjukkan adanya peningkatan rata-rata pemahaman dari 68,15% menjadi 84%. Peningkatan paling signifikan terlihat pada aspek teknis seperti pengenalan sensor dan penggunaan perangkat lunak Arduino IDE. Dari segi performa, robot Analog A memiliki waktu tempuh tercepat (18,70 detik) dan konsumsi daya terendah (0,64%), sedangkan robot Digital lebih kompleks namun belum optimal dalam lintasan uji terbatas. Survei kepuasan menunjukkan 98% peserta merasa puas terhadap kegiatan. Kegiatan ini terbukti efektif dalam meningkatkan literasi teknologi dan memberikan pengalaman belajar berbasis praktik yang bermakna, serta relevan dalam mendukung implementasi SDGs poin 4 tentang pendidikan berkualitas.

Abstract

The global discussion on conserving energy's importance has persisted, paralleling the surge in energy use over two decades. This rise presents challenges for local energy supply to diverse buildings. Designing energy-efficient buildings has become crucial in reducing energy usage and promoting sustainability. This research comprehensively analyzed and assessed thermal-cooling loads within an airport building using Panasonic software. The investigation primarily focuses on evaluating cooling load and thermal dynamics within the airport facility, emphasizing enhancing energy efficiency, and ensuring thermal comfort. Additionally, duct sizing design was conducted to achieve a comprehensive HVAC installation. From the result of the investigation, it was found that the highest Cooling Load at the airport occurs at 4:00 PM, aligning with the peak temperature resulting from heat transmitted into the building, reaching 263,591 Watts for the Airport Lounge and 82,202 Watts for the Luggage Room. Building energy management must be undertaken to minimize the energy consumption during that period. By thoroughly examining thermal-cooling loads within an airport building, this research contributes to decision-making for designing and operating HVAC systems, thereby advancing sustainable building practices.
