Abstract

The sustainability of vannamei shrimp (L. vannamei) aquaculture activities is very dependent on the health of the vannamei shrimp being reared, the health of the vannamei shrimp is greatly influenced by biotic (pathogenic bacteria) and abiotic (environmental stress) factors which together affect their survival. This study aims to analyze the relationship and distribution of salinity, dissolved oxygen, and pH variables for the distribution of Vibrio sp. The results show that the salinity has a strong effect on the presence of Vibrio sp. in the shrimp pond area with a value of 0.008495, while pH and dissolved oxygen did not have a strong influence on the presence of Vibrio sp. bacteria with values ​​​​of 0.470479 and 0.663797 respectively. Therefore, it was concluded that it is important to control the salinity value so that it is not too high or too low with a value in the range of 18 – 20 ppt. Then even though pH and dissolved oxygen do not affect the presence of bacteria, these two parameters greatly affect the vannamei shrimp immune system which can make it easier for Vibrio sp. bacteria to develop and infect.

Abstract

The primary challenge encountered in the production of tilapia is a bacterial disease that is induced by the bacterium Aeromonas hydrophila. Crop failure and the mortality of cultured animals are among the consequences. Certain herbal plants contain antioxidants that can exert a therapeutic effect against the A. hydrophila bacterium. The objective of this investigation is to ascertain the survival of fish following infection with A. hydrophila bacteria and their behavior and morphology prior to and following immersion in purple sweet potato leaf extract (Ipomoea batatas). In the initial stage, the survival rate was assessed through the challenge test with A. hydrophila 108 bacteria. The second stage involved the observation of the behavior and morphology before and after immersion in purple sweet potato leaf extract (I. batatas). This research was conducted in two phases. The treatment concentrations were as follows: treatment A (without extract / 0 mg/L), treatment B (40 mg/L), treatment C (60 mg/L), and treatment D (80 mg/L). In the research, abnormal behavioral changes, including the presence of red sores on the tail and a decline of appetite, were observed. The fish maintained an appetite, exhibited normal body movements, and swam actively when treated with D. Conversely, treatment A demonstrated a subpar response until the conclusion of the observation period. The effective inhibition of mortality in Nile tilapia was demonstrated by the survival rate of Nile tilapia larvae infected with A. hydrophila bacteria after treatment with a solution of purple sweet potato leaf extract (I. batatas) for 24 hours. The survival rate was observed over a 7-day period.

Abstract

The potential of the vast ponds is not comparable to the production of the Totobo Mandiri Sejahtera group's partners. The priority problems are sub-optimal pond fertilization, inadequate provision of fish feed, and poor cultivation management. Through the Community Partnership Empowerment program, the implementing team conducted training on composting and making independent fish feed, and demonstrated tilapia and milkfish cultivation in ponds. The raw materials for compost include chicken manure, bran, lime, and EM4. The compost fermentation process lasts three weeks. The compost produced in this activity is 2,100 kg. The production of independent fish feed uses raw materials such as corn, bran, dried fish, and EM 4. Corn flour is used at 36%, fine bran at 36%, fish flour at 28%, and EM 4 at 1% or more. The farmer group partners produce 600 kg of fish feed. This PKM activity also created a demonstration plot for tilapia and milkfish cultivation, 10,000 tilapia and 5,000 milkfish. Tilapia is harvested after 3-4 months, and milkfish after 4-5 months. The target production of tilapia and milk fish is 500-800 kg/ha

Abstract

The exploration and research abilities of students were substantially enhanced through training in mangrove data collection techniques conducted along the coast of Kendari Bay. The effectiveness of the theoretical sessions and field practice is evidenced by an increase in theoretical understanding scores from 65.8 to 82.4 and practical skills scores from 2.2 to 4.1. The training, which was attended by 45 students, produced a comprehensive database comprising 135 vegetation plots, identification of 12 mangrove species, as well as water quality and substrate data from three locations. In addition to improving technical skills, the training facilitated the formation of study groups and the development of collaborative research proposals, which in turn increased motivation and research collaboration among participants. The resulting data have been submitted to the Kendari City Environmental Agency as a foundation for mangrove management. The success of this program demonstrates that experience-based methodologies are effective in enhancing human resource capacity and supporting the sustainable conservation of mangrove ecosystems.

Abstract. Indrayani I, Haslianti H, Asmariani A, Muskita WH, Balubi M. 2020. Growth, biomass and lipid productivity of a newly isolated tropical marine diatom, Skeletonema sp. UHO29, under different light intensities. Biodiversitas 21: 1498-1503. Light is one of the important factors affecting growth and biochemical composition of microalgae. The aim of this study was to determine growth, biomass and lipid productivity of a newly isolated marine diatom, Skeletonema sp.UHO29 under different light intensities. The Skeletonema sp. was cultured in 300 mL conical flasks containing 150 mL of f/2 medium under three different light intensities (28, 60 and 110 ?mol photons m-2 s-1 ) with three replications. The cultures were incubated under ambient room temperatures, and a cycle of 12 hours light and 12 hours dark, in batch modes for two weeks. The results showed that the highest specific growth rate (0.56 d-1) was achieved at the highest light intensity (110 ?mol photons m-2 s-1) and the lowest (0.11 d-1) was obtained at the lowest light intensity (28 ?mol photons m-2 s-1). The highest biomass yield (0.62 g L-1) and biomass productivity (0.34 g L-1 d-1) was achieved at the highest light intensity. However, the highest lipid yield (0.175 g L-1), lipid content (28.78% ash-free dry weight) and lipid productivity (0.067 g L-1 d-1) were achieved at medium light intensity. The alga prefers high light intensity for higher growth rate and biomass productivity but it produces more lipids at medium light intensity. This study indicated that the Skeletonema sp.UHO29 is a potential species for outdoor mass cultivation and is a promising microalgal strain for use as a biodiesel feedstock due to its high growth rate, high biomass and lipid productivity.
