Penggunaan Biji Kelor (Moringa oleifera) Dengan Bentuk Yang Berbeda Sebagai Filter Terhadap Konsentrasi Amoniak Pada Budidaya Ikan Nila (Oreochromis niloticus) Dengan Sistem Resirkulasi

Abstract

This study aims to determine the use of moringa seeds (moringa oleifera) with different forms as a filter for ammonia concentrations in tilapia (Oreochromis niloticus) culture with a recirculation system. The method used in this study was a completely randomized design (CRD) with 4 (four) treatments and 3 (three) repetitions, namely treatment A = Filtration using dry moringa seed flour, treatment B = Filtration using coarse dry moringa seeds, and treatment C = Filtration using dry moringa seeds. The variables measured were ammonia concentration and water quality, such as measurement of temperature, pH, and dissolved oxygen. Data analysis used analysis of variance (ANOVA). If it has a real effect, then proceed with the Honest Significant Difference (BNJ) test at the level α = 0.05. The results showed that the effect of using moringa seeds (Moringa oleifera) in different forms as filters in the recirculating system for tilapia (Oreochromis niloticus) cultivation had no significant effect on ammonia concentrations. L. Temperature measurements during the study ranged from 26.3-28.0 ^oC.  Dissolved oxygen values ​​during rearing ranged from 4.65–5.08 mg/l. During the research, the pH value in this treatment, namely 6 ppm, was still tolerated by tilapia.
