Abstract

Logam berat merupakan satu dari banyaknya zat yang dapat mengkontaminasi suatu perairan yang tidak dapat dilarutkan bahkan dihilangkan oleh mikroorganisme sehingga dapat menyebabkan penumpukan dan pengendapan hingga ke dasar perairan. Akumulasi logam berat di perairan berdampak pada penurunan kualitas lingkungan yang dapat mengganggu ekosistem dan biota didalamnya seperti terumbu karang ikan karang, makrozobenthos, lamun dan lain-lain. Dampak tersebut menjadi salah satu potensi risiko kesehatan manusia akibat konsumsi ikan dan hidangan laut lainnya yang terakumulasi logam berat. Dalam dua dekade terakhir, penelitian logam berat telah banyak dilakukan oleh peneliti secara global, termasuk penelitian logam berat di Pelabuhan. Penelitian ini mengkaji tingkat kesusaian perairan akibat logam berat berdasarkan standar baku mutu perairan di pelabuhan Indonesia berdasarkan literatur yang tersedia.

Abstract

Feed is one of the important factors in fish farming, because it can account for 60–70% of the total operational costs of cultivation. The purpose of this study was to analyze the effect of providing water hyacinth (Eichhornia crassipes) fermented with Aspergillus niger as feed on the growth performance of tilapia (Oreochromis niloticus). This study used an experimental method and a Completely Randomized Design (CRD) consisting of five treatments and three replications, with the composition of P0 (commercial pellets) as the control, P1 (30% unfermented water hyacinth flour), and P2 (10%), P3 (20%), and P4 (30%) fermented water hyacinth flour. The results of this study showed that the addition of water hyacinth flour fermented with Aspergillus niger had no significant effect (P > 0.05) on tilapia protein retention. It was also known that the water quality in the tilapia maintenance media was within the optimal range.
