Abstract

Mangosteen peel (Garcinia mangostana) is known for its high concentration of bioactive compounds, particularly flavonoids, which possess various health benefits such as antioxidant, anti-inflammatory, and antimicrobial properties. This study aims to identify and quantify the flavonoid content extracted from mangosteen peels sourced from Mataram, West Nusa Tenggara. Using ethanol as a solvent, the extraction process was carried out through maceration, followed by qualitative and quantitative analysis using Fourier Transform Infrared Spectroscopy (FT-IR). The FTIR analysis confirmed the presence of key functional groups associated with flavonoids, including hydroxyl (-OH), ether (C-O), and aromatic C=C groups. Quantitative analysis revealed a significant flavonoid content. Additionally, the extract showed potential antibacterial properties against Aeromonas hydrophila, suggesting its application as a natural antimicrobial agent.

Abstract

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.
