Abstract

Zooxanthellae are single-celled microalgae that live symbiotically in coral tissue. The porpose of this study was to determine the abundance of zooxanthellae in massive and branching corals. The research method used was descriptive analysis. The sampling technique used direct field sampling by chisels, both on massive coral reefs or branching coral reefs. Observation of zooxanthellae was conducted in the laboratory using a microscope. The results obtained from the research indicate that massive corals have a relatively higher abundance of zooxanthellae with values of 109 x 105 cells/cm than branching corals with values of 73 x 105 cells/cm. In addition, massive corals are more resistant to bleaching than branching corals due to their large reserves of zooxanthellae and their ability to adapt to environmental stress.Keywords:AbundanceZooxanthellaeMassiveBranching

Abstract

Coral reefs are one of the ecosystems with the highest biodiversity. The purpose of this study was to determine the relationship of current velocity has on primary productivity in coral reef ecosystems. Current velocity measurements using a current meter and primary productivity measurements using the Winkler method by ƒincubated for 5 hours. The results obtained from this study are that current velocity has an effect on primary productivity in coral reef ecosystems, R value 0.895 and R Square shows 80.1%. The significance value obtained Sig = 0,04, which means less than 0.05, it can be interpreted that the effect of current velocity on primary productivity is strong category. Based on the study results obtained, more research is necessary to find out how much the velocity of the current affects the primary productivity of the coral reef.

Abstract

The pedada fruit (Sonneratia alba), locally known as posi-posi, has potential as a raw material for herbal tea with various health benefits, such as lowering cholesterol, relieving gout, providing antioxidant effects, reducing gastric acidity, and supporting organ health. However, mangrove tea has not yet been widely marketed in North Maluku, and it is not available as a local tourism souvenir. This Community Service Program (PKM) aimed to: (i) increase partners’ knowledge of mangrove fruit as a business opportunity, (ii) apply appropriate technology in tea processing, and (iii) produce high-quality mangrove tea variants with market value. The implementation stages included: (1) knowledge delivery through presentations and discussions, (2) mangrove exploration along the Guraping tourism tracking route, and (3) demonstration of mangrove tea processing. The product was developed into five variants: TeOry, Tebal, TeGo, TTM, and PosiNaga. Each variant was packaged in tea bags and boxes, then evaluated using hedonic organoleptic testing based on color, aroma, taste, and texture. The results indicated that mangrove tea has promising potential as a distinctive tourism souvenir and as a new business opportunity for local communities.
