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.

Abstract

Staurastrum is a microalgae from the family of Desmidiaceae which is abundant in freshwater. The purpose of this study was to determine the diversity of Staurastrum and the abundance of the population of Staurastrum in the Sentani Lake Jayapura. The study was conducted in March 2018 in the Sentani Lake Jayapura. The sampling method used was the survey method by sampling water in 6 locations (Kampung Yakonde, Ifale, Hobong, Kalkhote, Ayapo, Puay) on the edge and center of the lake. The results showed that 4 species of Staurastrum on the Sentani Lake were S. arachne, S. diacathum, S. gracile and S. incisum The abundance of the Staurastrum population highest at the location of Ayapo (103), Puay (94), Hobong (89), Kalkhote (81), Ifale (77) and Yakonde (8). In terms of the similarity index, there are 7 sampling points that are very similar, 23 that are similar, 20 that are dissimilar, and 16 that are very dissimilar. The difference in sampling location shows that sampling in the central part of the lakes has a higher population abundance compared to edge of the lake. In conclusion there are 4 species of Staurastrum, the location of Ayapo is higher in abundance, and the central part of the Lake is higher in abundance.    Key words: Desmidiaceae; Jayapura; Lake; Sentani; Staurastrum.
