Abstract

Utilization of various types of feed raw materials that have good nutritional value is an important part of fish farming activities. One type of raw material for fish feed, namely yeast (Saccharomyces Cerevisiae), has the potential as an immunostimulant to accelerate the growth of tilapia (Oreochromis niloticus). This study aims to determine the growth of tilapia (O. niloticus) by adding yeast Saccharomyces cerevisiae to tilapia (O. niloticus) commercial feed. The research was conducted for 60 days, at the Fish Seed Production Laboratory, Aquaculture Program, Faculty of Fisheries and Marine Sciences, Dayanu Ikhsanuddin University, Baubau. The test feeds used were the yeast Saccharomyces Cerevisiae and the commercial feed FF-999. The organism were tilapia (O niloticus) 5 – 7 cm measuring, in an aquarium 50 cm x 30 cm x 35 cm with a density of 10 individuals. The research design used a Completely Randomized Design, 4 treatments and 3 replications. The treatments consisted of treatments A (0% yeast), B (2% yeast), C (4% yeast) and D (6% yeast). The results showed that the highest absolute growth of tilapia occurred in treatment D (6% yeast) of 24.02 ± 1.64 grams and the lowest absolute growth in treatment B (2% yeast) namely 17.81 ± 1.84 grams. The best feed conversion in treatment D (6% yeast) was 2.49 ± 0.30. The highest survival rate was in C treatment (4% yeast) and D treatment (6% yeast), namely 93.33%. Based on the results of the analysis of variance, the addition of yeast to the feed affected the growth of tilapia (P<0.05). However, it had no effect on feed conversion and survival rate of tilapia (P>0.05).

Abstract

Cassava leaves (Manihot utilissima Pohl), like soybeans (Glycine max), have good nutritional to be used as raw material for alternative fish feed. The research was to determine the effect of cassava leaf flour (Manihot utilissima Pohl) and soybean (Glycine max) flour as artificial feed on the growth of tilapia (Oreochromis niloticus). It was conducted for 60 days at the Agricultural Extension Center, South Buton Regency. The organisms were gift tilapia seeds, weighing 5 – 7 grams, reared in plastic containers with a capacity of 40 liters, with a density of 10 fish/container. The feed made from cassava leaf flour, soybean flour, shrimp meal, fish meal, tapioca flour, vitamin mix, and mineral mix, was given as much as 5% of the total fish weight/day. The research design was a completely randomized design with 3 treatments and 3 replications, namely A treatment (15% cassava leaf flour and 25% soybean flour), B (25% cassava leaf flour and 15% soybean flour), C (35% cassava leaf flour and 5% soybean flour). The results showed the highest absolute growth and specific growth in B treatment (25% cassava leaf flour and 15% soybean flour) namely 17.38 ± 0.31 gram, and 2.24 ± 0.02%/day. The best FCR was 2.24 ± 0.02 in B treatment (25% cassava leaf flour and 15% soybean flour).

Abstract

The success of the aquaculture business is closely related to the optimum environmental conditions for the survival and growth of the fish being reared, so it is necessary to improve the aquatic environment. One of the filters that can be used to purify water is by utilizing activated carbon from kapok banana peels. Banana peels contain pectin and cellulose. The purpose of this study was to determine the effect of various uses of activated carbon from kapok banana skin (Musa acuminate L.) with different doses as a filter in a recirculation system on ammonia concentrations in tilapia (Oreochromis niloticus) aquaculture. The fish-rearing containers used were basins with a diameter of 50 cm and a height of 30 cm, totaling 12 pieces, while the filter containers in the form of PVC with a diameter of 3” were 12 pieces. 120 test organisms were used with a size of 5-7 cm. Feeding with a protein content of 25-30% is carried out 2 times a day at 08.00 and 16.00 WITA with a dose of 5% of body weight. This study used a completely randomized design (CRD) with 4 treatments and 3 replications, namely Treatment A (Usual Filtration), Treatment B (Filtration using activated carbon of kapok banana peels as much as 5 g), Treatment C (Filtration using activated carbon of kapok banana peels as much as 10 g) and Treatment D (Filtration using 15g of kapok banana skin activated carbon). The use of activated carbon in kapok banana peels can reduce ammonia levels and increase the survival rate in tilapia cultivation when compared to without the use of activated carbon in kapok banana peels.

Abstract

NASA POC is a liquid organic fertilizer that contains macro and micro nutrients, growth regulators and soil microorganisms. Because of this, NASA POC can be used as a raw material for feed to increase fish growth. Another local feed raw material that has high nutritional value and is relatively cheap and easy to obtain is tofu dregs flour. Purposeful research determine the growth and survival of tilapia when using Nasa POC and tofu dregs flour at different doses. This research was conducted for 8 weeks at the FPIK Research Ponds, Dayanu Ikhsanuddin University. The maintenance containers are made of 12 pieces of 18 liter plastic which are equipped with aeration. The test organism used tilapia (Oreochromis niloticus) seeds measuring 5-7 cm and weighing 5-6 grams originating from local fish farming ponds, with a density of 10 fish/container. The study used a completely randomized design with 4 treatments and 3 replications, namely A (0 ml POC Nasa and 0% tofu dregs flour), B (30 ml POC Nasa and 25% tofu dregs flour), C (20 ml POC Nasa and 30% flour tofu dregs), D (10 ml POC Nasa and 35% tofu dregs flour). The results showed that the use of POC Nasa and tofu dregs had an effect on the growth of tilapia (O. niloticus) (P<0.05). The highest absolute growth was in C treatment (20 ml POC Nasa and 30% tofu dregs flour) namely 7.91 ± 0.30 gr, and the lowest was in B treatment (30 ml POC Nasa and 25% tofu dregs flour) namely 6.11 ± 0.15 gr. The highest specific growth (% per day) was in C treatment (20 ml POC Nasa and 30% tofu dregs flour) namely 1.64 ± 0.06, and the lowest was in B treatment (30 ml POC Nasa and 25% tofu dregs flour) namely 1 .38±0.06. The survival rate for all treatments was 100%.

Abstract

Kadia Liya is one of the seaweed-producing areas in Wakatobi Regency, Southeast Sulawesi Province. Seaweed farming activities in this area continue to grow. The development of aquaculture activities continues to grow because it is influenced by fairly good water conditions. Remote sensing mapping technology is the best alternative for monitoring the condition of oceanographic parameters on a regional scale. This study aims to map oceanographic parameters including salinity, dissolved oxygen, and acidity in the Kadia Liya seaweed cultivation area, Wakatobi Regency, sampling has been carried out at 20 station points spread across the cultivation area. The satellite imagery used is the Sentinel-2A satellite imagery. The method used in data processing is the interpolation method used, namely Inverse Distance Weighting (IDW) using the ArcGIS 10.8 application. The results of observations of water conditions include salinity with a range between 30.3 - 37.1 per mile (‰), dissolved oxygen (DO) which is 4.7 mg / l - 9.5 mg / l, and acidity (pH) which is 6.0 - 8.5. In general, the condition of oceanographic parameters such as salinity, dissolved oxygen, and acidity at the research site is still relatively suitable for seaweed cultivation activities.
