The aim of this study was to determine the effect of butterfly pea leaf as a source of carotenoids on the quality of the color of the heads of swordtail fish. The study was conducted at the Aquaculture Laboratory, Building 4, Faculty of Fisheries and Marine Sciences, Padjadjaran University, from March to April 2019. The research method used an experimental approach with Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications. Those treatments are 0%, 1%, 6% and 12% of butterfly pea leaf meal. The parameters observed included changes in head color quality, absolute weight growth, absolute length growth and water quality. Color observation data were analyzed using Kruskal-Wallis analysis if there were differences between treatments. Multiple comparisons were performed with the Z test with a confidence level of 95%. Data on the length of growth rates and absolute weights were analyzed using analysis of variance via the F test. Here, 95% was set as the confidence level. If there were differences between treatments, this was followed by Duncan test with a confidence level of 95%. The results showed that the addition of 6% butterfly pea leaf meal in commercial feed was able to improve the best color on the part of the swordtail fish head. This saw an average color score 9.56 and color value of 82.2. Addition of carotenoids in feed, however, did not significantly influence the growth of absolute weight or length and water quality.

This research aims to determine the highest level of fermented Lemna sp. used in artficial feed to produce optimum growth rate of Nilem Carp. This research was conducted from March to July 2016, in the Ciparanje Laboratory and Aquaculture Laboratory of the Fisheries and Marine Science Faculty, Universitas Padjadjaran. The method used in this research is experimental, and is of a Completely Randomized Design (CRD). It consists of five treatments and three repetitions, providing one commercial diet (as control) and four fermented Lemna sp. levels (10%, 20%, 30%, and 40%). Collected data are analyzed with analysis of variance F-test at 95% confidence level. The parameters observed in this research are divided into four sub-parameters: nutrition changes of fermented Lemna sp., daily growth rate, feed conversion ratio and survival rate. The crude fiber content of Lemna sp. was reduced from 18.37% to 13.57%, and protein content increased from 19.37% to 23.47%, respectively, after fermentation. Based on the results of this research, fermented Lemna sp. used in fish feed at 40% level produced the best results: a daily growth rate at 0.75%, a feed conversion ratio at 3.61 and a survival rate of up to 100%.
