Abstract

This community service program was conducted to enhance the entrepreneurial capacity of junior high school students by strengthening their technical literacy in catfish aquaculture, a fisheries commodity with substantial economic value. The activity was implemented from 3–7 November 2025 at SMP Sumbarrang, Gowa Regency, and was delivered in a theoretical format due to limited facilities for practical aquaculture activities. The training materials covered the concept of youth agropreneurship, household-scale catfish farming techniques, feed management, community-based marketing strategies within the school environment, business feasibility analysis, and the development of entrepreneurial action plans. The methods employed included interactive lectures, group discussions, business plan simulations, and pre–post test evaluations. The results indicated a significant improvement in students’ technical literacy, reflected by a 49–50% increase in understanding related to farming techniques, feed management, and market opportunities. Entrepreneurial motivation also increased among 78% of participants, demonstrated by greater willingness to express business ideas and heightened awareness of their family’s economic potential. Support from schools and parents was identified as a key factor strengthening the sustainability of the program. Overall, this activity produced a replicable empowerment model for cultivating young agropreneurs in rural school settings, contributing to local economic development through the fisheries sector.

Abstract

Microplastics are emerging pollutants widely detected in freshwater ecosystems, including rivers that act as major pathways for plastic waste transport to the ocean. This study aimed to analyze the abundance and characteristics of microplastics in water, sediment, and fish from the middle section of the Kahayan River and to assess their implications for the sustainability of floating net cage aquaculture. Sampling was conducted at five stations representing different levels of anthropogenic activity. Water, sediment, and fish samples were processed using the wet peroxide oxidation (WPO) and NaCl density separation methods, followed by microscopic identification. The results revealed that microplastics were widely distributed across all environmental compartments, with mean abundances of 3,14 particles/L in water, 7,31 particles/kg-dw in sediment, and 3,63 particles/individual in fish. The highest concentrations were found in stations with intensive aquaculture, dense settlements, and active trading areas. The dominant types were fibers and fragments, mainly white, blue, and black/gray in color. Particles <300 µm predominated in water and fish, whereas those >1000 µm were more abundant in sediment. These findings indicate the transfer of microplastics from abiotic to biotic components, suggesting potential bioaccumulation within the aquatic food chain. The presence of microplastics in aquaculture environments may degrade water and fish quality, posing threats to aquaculture sustainability and food safety for local communities along the Kahayan River.
