Abstract

Development of lobster cultivation activities in Muna regency relatively not optimal.  Availability of feed is be expected to be an obstacle in the development of lobster cultivation.  This Research aims to determine the effect of feed ingredients on growth and survival of spiny lobster (Panulirus versicolor).  The Research was conducted in December 2017 to March 2018, located in Bahari Village, Towea District, Muna Regency, Southeast Sulawesi Province using a randomized block design with three levels of feed ingredients treatment namely treatment A = blood clam meat, treatment B = white shrimp and treatment C = trash fish. The results showed that the highest specific growth rate was obtained in treatment A which was 1.69 ± 0.09 %/day, then treatment C (1.13±0.09 %/day), and the in lowest treatment B (1.09±0,06 %/day). The highest absolute growth was obtained in treatment A of 606.67 ± 15,28 g/individual then treatment C was 336.67±15,28 g/individual and the lowest was in treatment B of 300.00±10.00 g/individual. Survival of sea lobster is 100% in all three treatments. Analysis of variance at the 95% confidence level (α0.05) showed that different feed ingredients had a significantly different effect on the daily growth rate, and the absolute growth of sea lobsters (P. versicolor).

Abstract

The objective of this study is to determine the impact of feeding tempeh dregs at varying doses on tilapia growth and survival (Oreochromis niloticus). The study was conducted from March to May 2023 in Wataliku Village, Kabangka District, Muna Regency. The study employed a completely randomized design with four treatments that involved the administration of tempeh dregs in the diet. These were designated as follows: treatment A (control) was commercial feed; treatment B was 10% tempeh dregs; treatment C was 15% tempeh dregs; and treatment D was 20% tempeh dregs. Each treatment was replicated three times. The data were subjected to analysis of variance (ANOVA) at a confidence level of 95% (α0.05). The study results demonstrated that the highest specific growth was observed with the addition of 20% tempe dregs, with an average of 2.97% per day. This was followed by 15% tempe dregs (2.47% per day), 10% tempe dregs (2.28% per day), and commercial feed (2.00% per day). The highest absolute growth was observed in the treatment that included 20% tempe dregs, with an average of 1.04 g per individual. This was followed by the treatment that included 15% tempe dregs (0.87 g per individual), the treatment that included 10% tempe dregs (0.80 g per individual), and the treatment that included commercial feed (0.00 g per individual). It should be noted that survival was 100% in all treatments. Analysis of variance (α0.05) demonstrated that administration of tempe dregs at varying doses had a statistically significant impact on the specific and absolute growth of tilapia larvae (Oreochromis niloticus).

Abstract

Catfish has various advantages, including fast growth, high adaptability to the environment, delicious taste, and high nutritional content.  As a source of nutrition for reared fish, feed is a factor that plays a very important and decisive role in the success of fish farming.  The research aims to determine the effect of feeding frequency on the growth and survival of sangkuriang catfish larvae (C. gariepinus). The study was conducted from June to July 2020 at the Abelisawa Fish Seed Center (BBI), Sampara District, Konawe Regency, South East Sulawesi Province using a Completely Randomized Design with three frequencies of feeding treatment, namely treatment A feeding twice a day, treatment B feeding 3 times a day and treatment C feeding 4 times a day with 3 replications.  Data were analyzed using Analysis of Variance (ANOVA) at 95% confidence level (a 0,05).  The results obtained the highest daily growth in treatment B of 3.11 ± 0.04% per day, followed by treatment A of 2.58 ± 0.05% per day and the lowest in treatment C of 2.53 ± 0.03% per day.  The highest absolute growth was obtained in the frequency of feeding 3 times a day at 37.27 ± 0.20 g per individual, followed by 2 times a day at 27.64 ± 0.40 g per individual and the lowest at feeding 4 times a day at 26.51 ± 0.92 g per individual. Survival in all 3 treatments reached 100%.  Analysis of variance (α 0.05) shows that different feeding frequencies significantly affect the daily growth rate (0.05>0.00) and absolute growth (0.05>0.00) sangkuriang catfish larvae (C. gariepinus).

Abstract

Crab (Portunus pelagicus) is a fishery export commodity, especially to Japan, the European Union and the United States. On the other hand, the crab part, namely the shell, is still not utilized optimally so it becomes waste. To make crab shells valuable, several studies have revealed the presence of useful substances known as chitin and chitosan. Therefore, this research was carried out with the aim of knowing the effect of deacetylation temperature on the quality of chitosan and the optimal deacetylation temperature so as to produce good quality chitosan. Method: This study employs an experimental methodology based on Fully Randomized Design (CRD) analysis. Several deacetylation temperature treatments (00C, 900C, 950C, 1000C, 1050C, 1100C, 1150C, 1200C) were repeated three times in this study's design. Analyses of yield, moisture content, ash content, protein content, and acetyl content serve as test parameters. Result: The results showed that the treatment using different deacetylation temperatures had a very significant effect (Fcrit > Ftable 1%) on water content, ash content, protein content, acetyl content and had no significant effect (Fcrit > Ftable 5%) on the yield. The optimal deacetylation temperature was 1200C, with a yield of 19.050%, water content of 8.340%, ash content of 0.022%, protein content of 0.198%, and acetyl content of 84.870%. Conclusion: The conclusion based on analysis that the best temperature deacetylation in producing quality chitosan crab is 1200C.

Abstract

Seaweed possesses the potential to serve as a functional food or supplement, being nutrient-dense and a source of food and medicine due to its abundance of minerals, vitamins, and antioxidants. In Indonesia, seaweed is extensively utilized due to its advantageous properties for multiple industries, including agriculture, animal husbandry, pharmaceuticals, chemicals, and medicine. This study seeks to discover a specific component of sea grape (Caulerpa racemosa), which is prevalent in the waters of Lohia Village, Lohia District, Muna Regency, Southeast Sulawesi. The composition of sea grape (Caulerpa racemosa) was analyzed utilizing an X-ray Fluorescence Spectrometer (XRF) due to its capacity to detect nearly all minerals in a single measurement. The study's findings indicated that sea grapes (Caulerpa racemosa) at stations 1, 2, and 3 contained Chlorine (Cl), Calcium (Ca), Potassium (K), and Bromine (Br), along with several trace elements including Iron (Fe), Phosphorus (P), Strontium (Sr), Silicon (Si), and Titanium (Ti) in minor quantities. At stations 4, 5, and 6, sea grapes (Caulerpa racemosa) predominantly exhibited Chlorine (Cl), Potassium (K), and Magnesium (Mg), whereas Calcium (Ca) and Bromine (Br) were present in lesser quantities. Despite the considerable benefits of sea grapes (Caulerpa racemosa) for humans, caution is imperative in their use. Sea grapes (Caulerpa racemosa) possess the capacity to absorb minerals and bioaccumulate heavy metals from seawater, resulting in the presence of trace elements.
