Abstract

Goldfish (Carassius auratus L.), one of the most popular and freshwater ornamental fish to be cultivated in Indonesia. One obstacle in the cultivation of Carassius auratus L. is the high feed cost (60-70%) of the total production cost. The natural food source for fish Carassius auratus L. is Tubifex sp. which has a high nutritional content. The aim of the study was to determine the dosage of Tubifex sp. best for the growth and survival rate of goldfish (C. auratus L.). This research was conducted at the Laboratory of Water Quality and Aquatic Biology, Faculty of Animal Husbandry and Fisheries, Tadulako University for 2 month (January to March 2020). The experimental design used a Completely Randomized Design (RAL) with 5 treatments and 4 replications. The treatment in this study was the administration of silk worms with different doses (A = 6%; B = 8%; C = 10%; D = 12%; E = 14%). The variables measured included absolute weight growth, survival and water quality. Data were analyzed by analysis of variance (ANOVA), with further tests BNJ using Excel 2010 and Minitab 16 application programs. The results showed that the natural feed (Tubifex sp.) shows a significant growth in absolute weight, but has no effect on survival. The absolute growth of goldfish seeds was the highest in the feeding of Tubifex sp. with a dose of 12% of 14.82 ± 2.76 g with a survival rate of 90.63% ± 6.25. Water quality (temperature, pH, dissolved oxygen and ammonia) is still in accordance with the growth needs of goldfish fry.

Abstract

This study was conducted to determine the ability of aquaponic systems using different numbers of water spinach (Ipomea aquatica) clumps in reducing ammonia in tilapia (Orechromis niloticus) culture. This study was designed in a Completely Randomized Design (CRD) with 5 treatments and 4 replicates, namely Treatment A (without water spinach), B (3 clumps of water spinach), C (6 clumps of water spinach), D (9 clumps of water spinach) and E (12 clumps of water spinach). This study was conducted for 60 days in November-December 2018 at the Fish Reproduction Laboratory, Brawijaya University, Malang. The results showed that the use of different numbers of water spinach clumps in the aquaponic system had a significant effect (P<0.05) on the reduction of ammonia and nitrite concentrations, but had no significant effect (P>0.05) on the reduction of nitrate and absolute growth of tilapia. The highest ammonia and nitrite reduction concentrations were found in the treatment of 12 water spinach clumps 84.31% and 69.88%, respectively.

Abstract

The purpose of this study was to determine the nutrient content of the bioconverted palm oil sludge using Rhizopusoligosporus so that it is suitable as functional feed. The used materials were oil palm mud flour and Rhizopusoligosporus fungus. The research design used a factorial completely randomized design with 8 treatments and 3 replications. The treatment consisted of two factors, the first factor was 4 concentrations, namely (0%, 5%, 10% and 15%) and two fermentation times, namely (60 and 96 hours). All treatments were analyzed for nutrient content including dry matter content (BK), crude protein (PK) and crude fiber (SK) fermented palm sludge. The results of the analysis of variety showed that the treatment had a very significant effect (P <0.01) on the content of BK, PK, SK and there was an interaction between the concentration of fungi and fermentation time on SK. The highest dry matter content for BK was obtained in W2K15 treatment (83.24%), PK on W2K15 (18.44%), and SK on W2K15 (24.00%).

Abstract

This study aims was to determine the effect of giving turmeric flour (Curcuma Domestica Val) in the rations on the percentage of super native chicken carcass.In this study, 80 super native chickens were placed in 20 cages with 4 chickens in each cage. The method used in this study was the completely randomized design method (CRD) with 4 treatments and 3 replications. The treatments used in this study were A (without turmeric flour or control), B (2% turmeric flour), C (4% turmeric flour), and D (6% turmeric flour). The variables observed were live weight, carcass weight, and carcass percentage. The results showed that the addition turmeric flour (Curcuma Domestica Val) had no significant effect on live weight, carcass weight, and carcass percentage of super native chicken. Giving turmeric flour to a level of 6% did not affect live weight, carcass weight, and carcass percentage.
