Abstract

Di era sekarang ini dunia telah memasuki revolusi industri 4.0. Pesatnya perkembangan teknologi tersebut berdampak pada peningkatan aktivitas manusia akan kebutuhan material terbarukan sebagai pengembangan dalam kehidupan sehari-hari. Anodic Aluminium Oxide (AAO) diperkenalkan sebagai material dengan permukaan berpori ukuran nano yang memiliki fungsi spesifik dalam berbagai disiplin ilmu. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh variasi beda potensial terhadap struktur permukaan dan ukuran pori pada material Anodic Aluminium Oxide. Variasi beda potensial yang digunakan 40 Volt, 50 Volt dan 60 Volt selama 10 jam. Pada penelitian ini AAO disintesis menggunakan metode Mild Anodizing dengan prinsip two-step anodization menggunakan Material Al-6061. Material hasil proses sintesis dilakukan pengujian SEM, Untuk struktur permukaan didapat variasi perbedaan yang mencolok di setiap variabelnya. Persebaran pori terbanyak didapatkan pada rata-rata 377.753 pada 40 volt, 510.137 pada 50 volt dan 872.195 pada 60 volt. Terjadi peningkatan rata-rata pori terbanyak seiring peningkatan potensial. Hasil ukuran pori yang diperoleh dari penelitian dapat digunakan sebagai bahan membran dasar pembuatan nano-desalinator untuk aplikasi desalinasi air laut. ========================================================================================================== In this new era, the world has entered the 4.0 Industrial Revolution, The rapid development of these technologies has an impact on increasing human activity in renewable materials used as a development for needs in daily life. Anodic Aluminum Oxide (AAO) was introduced as a nano-sized porous surface material that has specific functions in various disciplines. The purpose of this research are to synthesize and to analyze the effect of variations in potential differences on the surface structure and pore size of the Anodic Aluminum Oxide material. The potential difference variations used are 40 volts, 50 volts and 60 volts for 10 hours. In this study, AAO was synthesized using the Mild Anodizing method with the principle of two-step anodization using Material Al-6061. The material produced by the synthesis process is tested for SEM. For the surface structure, there are striking variations in each variable. The highest pore distribution was found at an average of 377,753 at 40 volts, 510,137 at 50 volts and 872,195 at 60 volts. There is an increase in the average pore most with increasing potential. Pore size results obtained from the study can be used as a basic membrane for the manufacture of nano-desalinator for seawater desalination applications.
