Abstract

Bintang pomfret is an introduced fish from Taiwan and has quite good prospects in the Asia Pacific region with quite high prices. This Final Practical Work Activity (KPA) aims to carry out a t-test and to determine the effect of water quality on growth, the correlation coefficient (r calculation) is calculated. The water quality parameters observed included temperature, pH and salinity. The t-test results showed that t calculated (0.008) < t table (), this means there was no significant difference between the two growth patterns in length and weight. Meanwhile, the results of the correlation coefficient between water quality and growth show that there is no real influence between the water quality parameters observed on the growth of the pomfret.

Abstract

This study was conducted to understand the growth pattern of tilapia (Oreochromis Niloticus) when cultivated in earthen ponds with a fixed net cage system. The location of the practice is at PT. Suri Tani Pemuka Rengasdengklok, Karawang, West Java. The main focus of this activity is to see the relationship between the length and weight of fish during the maintenance period, as well as to assess the comparison of the growth of length and weight of fish for each sampling and the survival rate (SR) of fish. From the results of the observation, it is known that the b value in the analysis of length and weight is 0.72220, which indicates that growth is negative allometric - meaning that fish grow faster in length than in weight. In addition, the survival rate of fish reached 76.4%, which is quite high and indicates that the maintenance conditions are running quite well. Fixed net cages (KJT) are a fish maintenance method that has several advantages, namely it can avoid water predators and is able to limit the circulation of fish so that it facilitates harvesting, but the growth rate is still influenced by other factors including water quality and feed. With this method, fish can grow more safely and optimally. It is hoped that the results of this practice can be an illustration and reference for other cultivators who want to apply similar methods.

Abstract

Kualitas air pada budidaya ikan sangat mempengaruhi pertumbuhan ikan yang dibudidayakan. Penurunan kualitas air disebabkan oleh limbah organik dari sisa pakan yang tidak termakan dan hasil metabolit ikan, limbah tersebut umumnya didominasi oleh senyawa nitrogen dan senyawa fosfor. Solusi untuk mengatasi masalah dalam memperbaiki kualitas air adalah fitoremediasi (upaya pengolahan air limbah menggunakan tanaman). Tanaman yang berpotensi sebagai fitoremediator adalah W. arrhiza. Tujuan penelitian adalah untuk mengetahui pengaruh fitoremediasi W. arrhiza terhadap kinerja budidaya ikan nila. Penelitian ini menggunakan pendekatan kuantitatif, dengan menggunakan tanaman uji W. arrhiza dengan yang jumlah berbeda yaitu P0 (kontrol), P1 (50 g/m2), P2 (150 g/m2) dan P3 (250 g/m2), ikan uji yaitu Ikan Nila. Penelitian dilaksanakan di Kelompok Pembudidaya Ikan Cing Mina Fish Farm Kabupaten Bogor. Hasil penelitian yang dilakukan selama 30 hari menunjukkan bahwa pemeliharaan ikan nila dengan sistem fitoremediasi menggunakan W. arrhiza memberikan pengaruh nyata terhadap tingkat kelangsungan hidup dan rasio konversi pakan (P<0.05), akan tetapi tidak berpengaruh nyata terhadap pertumbuhan panjang baku, pertumbuhan berat mutlak dan laju pertumbuhan harian (P>0.05). Perlakuan P3 menunjukan nilai tertinggi pada parameter tingkat kelangsungan hidup dan rasio konversi pakan dengan nilai 94,17±0,76% dan 1,3±0,09. Sedangkan pertumbuhan berat mutlak dan laju pertumbuhan mutlak tanaman uji mempunyai nilai tertinggi terdapat pada perlakuan P1 dengan nilai 834±97,68 g dan 27,80±3,26 g.
