PENGARUH KOMBINASI PAKAN ALTERNATIF DENGAN PERSENTASE YANG BERBEDA TERHADAP TINGKAT KELANGSUANG HIDUP DAN PERTUMBUHAN BENIH LOBSTER AIR TAWAR (Cherax quadricarinatus) DI UPR KURNIA KABUPATEN MAROS
Freshwater lobster (Cherax quadricarinatus) is a high-value aquaculture commodity with rapid growth and strong adaptability. However, the high cost of feed—accounting for 60–70% of total production expenses—remains a major constraint for farmers. The use of alternative plant–animal feed combinations offers a potential solution to reduce production costs without compromising nutritional quality. This study aims to analyze the effect of different proportions of alternative feed combinations on the absolute weight gain of freshwater lobster juveniles, determine the most optimal feed composition, describe growth patterns, and evaluate water quality as a supporting factor. The research was conducted for four weeks using an experimental method with a Completely Randomized Design (CRD) consisting of five treatments and five replications. The results showed that feed combinations had a highly significant effect on growth. Treatment D (25% plant-based + 75% animal-based feed) produced the highest absolute weight gain of 10 g, indicating that animal protein plays a dominant role, while plant-based nutrients remain essential for balanced nutrition. Overall, plant–animal alternative feed combinations effectively enhanced the growth of freshwater lobster juveniles and present a cost-efficient alternative to commercial feed for farmers.

ANALISIS DAMPAK SOSIAL EKONOMI PEMBANGUNAN BREAKWATER PADA KOMUNITAS PESISIR DI PELABUHAN PERIKANAN BEBA, TAKALAR, SULAWESI SELATAN
Breakwater construction in coastal areas is essential for enhancing port stability and ensuring the safety of fisheries activities; however, the construction phase often generates socio-economic pressures on communities dependent on port operations. This study aims to analyze the impacts of breakwater development at Beba Fishing Port, Takalar District, with a focus on changes in fishermen’s income, local economic dynamics, and social disturbances during construction. The research employs a mixed-methods approach with an explanatory sequential design, which integrates quantitative and qualitative analyses in a sequential manner. The initial phase involved a survey of 40 respondents—including fishermen, fish traders, small-scale entrepreneurs, and nearby residents—followed by in-depth interviews and field observations based on Participatory Action Research. Chi-square analysis was used to assess the relationship between demographic characteristics and levels of impact. The findings indicate that fishermen’s income decreased by 11% during construction due to operational disruptions at the port but increased by 6% after the breakwater became fully functional. Economic impacts were more pronounced among fishermen and fish traders (χ² = 8.0; p < 0.05). Socially, communities experienced conflict, pollution, and environmental discomfort, particularly in areas affected by heavy-equipment traffic. Inferential analysis revealed significant associations between age (χ² = 11.73; p < 0.01) and education level (χ² = 8.10; p < 0.05) and conflict experiences, with younger and less-educated groups being the most affected.

PENGELOLAAN PESISIR DAN KELAUTAN DALAM STUDI KASUS PENGELOLAAN EKOSISTEM BAKAU DI KOTA PARIAMAN
Mangrove ecosystems are an important component of coastal areas that have strategic ecological functions, including acting as natural coastal protection from abrasion, providing habitat and seeds for fisheries, and absorbing carbon that plays a role in mitigating climate change. However, the existence of mangrove ecosystems in various coastal areas of Indonesia, including Pariaman City, faces serious pressure due to human activities and weak coastal area governance. The problem formulation in this study includes the factors causing problems in the mangrove ecosystem in Pariaman City and how the central role of coastal area governance can strengthen the ecological function of mangroves as coastal protection, providing seeds for fisheries, and absorbing carbon. This study aims to analyze the role of management and protection of coastal ecosystems, especially mangrove forests, in the governance of the coastal area of ​​Pariaman City. The research methodology uses a literature review method with a descriptive analysis approach, which examines 15 selected articles. The results of the study indicate partial to significant degradation of mangrove areas due to land conversion, reclamation, logging, and industrial and household pollution. Human pressures such as shrimp pond expansion, coastal infrastructure development, and land reclamation also exacerbate abrasion and reduce the productivity of the mangrove ecosystem. On the other hand, mangroves have significant potential as an instrument for climate change adaptation and mitigation through increasing blue carbon and coastal rehabilitation. Therefore, this study emphasizes the importance of community-based governance policies, mangrove restoration programs, and cross-sector partnerships to maintain the sustainability of Pariaman City's coastal ecosystem.
