Opis:
Many tropical plants have interesting biological activities with potential therapeutic applications. Garcinia mangostana Linn. (GML) belongs to the family of Guttiferae and is named “the queen of fruits”. It is cultivated in the tropical rainforest of some Southeast Asian nations like Indonesia, Malaysia, Vietnam, Philippines, and Thailand. This research aims to determine the concentration of solution mangosteen rind (Garciana mangostana) which is the most effective to healing of black tilapia juvenile (Oreochromis niloticus Bleeker) when infected by A. hydrophila bacteria to produce the highest survival of black tilapia juvenile. This research used experimental method and experimental design by including a complete randomized design (CRD) with five treatments and three replications. The used treatment was soaking black tilapia juvenile for 24 hours in mangosteen rind. The sample infected by A. hydrophila bacteria as much as 0.1 mL/fish at concentration of 108 cfu/mL with intramuscular injection method was used. The concentrations of mangosteen rind solution were 0, 500, 600, 700, and 800 ppm. The parameters observed were clinical symtoms, fish response to feed, fish response to shock, recovery process, and water quality. Data of the clinical symtoms, response fish to feed, response fish to shock, recovery process and water quality were analysed descriptively, while the survival rate data of black tilapia juvenile were analysed using F test at 95% confidence level and continued with Duncan test. The results showed, the use of mangosteen rind solution with 600 ppm concentration was effective to treat tilapia juvenile which infected by A. hydrophila bacteria resulted in the fastest recovery on the third day and the highest survival rate of 91.76.

Opis:
The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1, 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.

The purpose of this study was to distinguish histopathological changes in carp fish (Carassius auratus) infected by Aeromonas hydrophila with different densities. Five treatments were used in the survey for this research method. The treatments used were bacterial infusion of A. hydrophila in the test fish through intramuscular injection with various densities, namely: A. without infection, B: 105 CFU/mL, C: 106 CFU/mL, D: 107 CFU/mL, and E: 108 CFU/mL. The parameters observed were histopathological changes in gill organs, kidneys and hearts of carp fish (gold fish). Data from histopathological observations were analyzed descriptively. The results present gill organs, liver and kidneys of carp fish infected with the bacteria A. hydrophila at various densities experiencing histopathological changes in the form of hemorrhages, necrosis and congestion and hyperplasia of the renal tubules. Other changes that occur were in the kidney organ experiencing a melanomacrophage center (MC). Tubules were coated with connective tissue and lymphocyte infiltration. The most severe organ damage that occurs in carp fish infected with the bacteria A. hydrophila at a density of 108 CFU/mL (treatment E) is shown by a low survival of 5%.

Opis:
Using water hyacinth as a phytoremediation agent produces abundant biomass due to periodic harvesting in the system. One of the alternative uses of water hyacinth biomass can be a bio-sorbent to absorb metal contamination in the waters. This study aims to determine the quality of activated water hyacinth bio-sorbent, potentially reducing metal cadmium (Cd). The research was conducted from January to April 2022. The results showed that the parameters of water content, iodine absorption, and methylene blue in water hyacinth bio-sorbent had met the quality standard of activated carbon based on SNI No. 06-3730-1995. In contrast, the ash content still did not. In water, hyacinth stem bio-sorbents (stems + ZnCl2 and stems 300 °C + ZnCl2) obtained higher ash content (25.87 and 73.30%) than the ash content of water hyacinth root and leaf bio-sorbent with the same activation treatment. The optimum adsorption capacity (Qe) for the roots + ZnCl2 occurred at a contact time of 45 minutes which was 8.13 mg/g with an absorption efficiency (Ef) of 34.20%. For the root 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours, namely 9.08 mg/g and 38.66%, respectively. The optimum adsorption capacity and absorption efficiency of the leaves + ZnCl2 occurred at a contact time of 4 hours, namely 7.63 mg/g and 32.12%, respectively. Meanwhile, at the leaves 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours with a value of Qe = 11.84 mg/g and Ef = 49.35%.
