Abstract

The Wali Nibhi Reading House Group, also known as the Yoboi Reading House, was established in November 2019 in Yoboi Village, Sentani, Papua, with a focus on literacy improvement and women's empowerment. The group is predominantly composed of women, making it well-suited to develop skills in producing snakehead fish chips. However, they still face challenges in terms of skills and facilities. The existing skills are not yet sufficient to process fish into value-added products. The community's high dependence on the fisheries sector makes the local economy vulnerable to fluctuations in catch and environmental impacts. Training on processing snakehead fish into low-calorie chips through baking could address these issues. The method used is community-based training. Training in the production of fish stick chips and atom crackers has provided the community with new knowledge and skills. This program is crucial for local economic empowerment, teaching processing techniques and entrepreneurial skills that can increase income and well-being. The training utilizes local natural resources and strengthens the community's self-reliance and competitiveness in a broader market.

Abstract

The red devil fish (Amphilophus spp.) is a carnivorous fish from Nicaragua that is considered a pest due to its predatory nature toward smaller fish. Although it does not have high economic value, this fish reproduces rapidly and threatens the endemic fish population in Lake Sentani, Papua. The endemic fish population has declined due to the increasing population of red devil fish that live in colonies in the littoral zone. Despite its high amino acid content, this fish is less favored due to the abundance of bones. One way to increase its consumption is by processing it into crackers. The method used involves training the community. The goal of this activity is to increase the consumption of red devil fish among the community. The results and achievements of this activity show that the women of Yoboi village successfully utilized the previously underutilized red devil fish by processing it into crackers. This has had a positive impact on maximizing local potential and creating new business opportunities, thereby improving economic welfare. This activity has also enhanced food processing skills within the community.

Abstract

The natural tourism area of Teluk Youtefa in Jayapura City is known for its mangrove forests, rich in biodiversity, particularly Avicennia alba. Mangroves serve as coastal buffers, pollutant filters, and habitats for various flora and fauna. However, climate change, pollution, and human activities can affect the ecological balance and bioactive compound content of A. alba, which has long been recognized as a potential source of medicinal and natural antioxidant compounds. Fluctuations in water quality, invasive species, and land-use changes may disrupt both the ecosystem and the complexity of its bioactive constituents. Understanding the impact of environmental factors on both aspects is crucial for effective and sustainable conservation. This study aims to explore the relationship between environmental factors and the production of bioactive compounds in mangroves. The research investigates how environmental changes influence the ecological balance and bioactive content of Avicennia alba, and their implications for the sustainability of the Teluk Youtefa mangrove tourism area. Sampling was conducted using a purposive sampling method, focusing on environmental parameters such as temperature, salinity, pH, dissolved oxygen (DO), biological oxygen demand (BOD), and total suspended solids (TSS), along with laboratory analysis of bioactive compounds. The results show that the site with poor environmental quality (Site 1) recorded DO at 3.2 mg/L, BOD at 5.8 mg/L, and Pb at 0.07 mg/L. In contrast, the site with better environmental conditions (Site 3) showed DO at 5.5 mg/L, BOD at 2.1 mg/L, and salinity at 32.4 ppt. The bioactive compounds identified include Wagner’s alkaloids, Dragendorff’s alkaloids, flavonoids, terpenoids, saponins, and tannins. The polluted site (Site 1) yielded only three compounds—flavonoids, terpenoids, and saponins—whereas the conservation site (Site 3) revealed the full set of six bioactive compounds, including alkaloids and tannins. These findings indicate that environmental quality has a direct influence on the complexity of bioactive compounds and the ecological potential of mangrove ecosystems.
