Abstract

Penelitian yang telah dilakukan bertujuan untuk memodifikasi pori keramik berpori berbahan dasar pasir silika dan lempung menggunakan anodizing technique. Pembuatan keramik dilakukan secara manual dengan pengeringan selama 5 hari dan pembakaran pada suhu 945oC serta penahanan selama 2 jam. Setelah proses fabrikasi, dilakukan proses anodizing dengan lima variasi waktu yaitu 10 menit, 15 menit, 20 menit, 25 menit, dan 30 menit dengan menggunakan tegangan 20 volt serta kerapatan arus 25 mA/cm2. Hasil penelitian menunjukkan nilai porositas dan laju alir keramik mengalami peningkatan masing-masing dalam rentang 0,39% hingga 0,66% dan 6,67% hingga 8,87% setelah diberi perlakuan anodizing. Keramik dengan lama waktu anodizing 20 menit menghasilkan nilai porositas dan laju alir optimum yakni 32,37% dan 0,159 mL/menit.
