Pemanfaatan Karbon Aktif Kulit Pisang Kepok (Musa Acuminate L.) Pada Sistem Filtrasi Budidaya Ikan Nila (Oreochormis Niloticus)

Abstract

Banana peel production increases every year, but the utilization of banana peels is not optimal yet. Banana peel contains cellulose which can be used to absorb pollutants including heavy metals. The purpose of this research was to determine the best thickness of the activated carbon of banana peel in filtration system of tilapia (Oreochromis  niloticus) culture. This research used the Completely Randomized Design (CRD) with 4 treatments and 3 replications. Treatment were differences thickness of activated carbon of banana peel i.e (P1) control, (P2) thickness of 5 cm (P3) thickness of 10 cm, (P4) thickness of 15 cm. The results showed that the most efficient treatment was P₃ in 30 days cultivation with pH 7.0, temperature 28.6 ^oC, dissolved oxygen 4.10 mgL^-1, ammonia 0.09 mgL^-1, turbidity 42.65 mgL^-1, Zn 0.03 mgL^-1, Fe 0.29 mgL^-1, 86% of survival rate, 2.53 cm of absolute length growth, 3.33 gram of absolute weight growth and 72.92% of feed efficiency.
