Cerithidea quadrata (suction snail) is a gastropod species from the Sungsang coastal area and is a marine biota that has potentially toxic secondary metabolite compounds. The presence of this species in the Sungsang coastal area is quite dominant compared to other species so that it has great potential to be utilised as a medicinal material. The research was conducted to analyse the toxicity le…

Ecosistem of mangrove represent switchover ecosistem between land and sea that have a habitat, spawning ground, nursery ground and feeding ground from kind of fish, as crustacea, mollusc. Gastropods represent amount of mollusc that have a habitat in mangrove forest. This research is detain to see a relationship between gastropods density and mangrove density which is done on march 2006 whitch t…
Bivalves and gastropods serve as bioindicators of the aquatic environment to identify pollution in a coastal area. It is suspected that there is a decrease in biodiversity in the waters of the Alor Islands, East Nusa Tenggara due to anthropogenic activities that cause an area to be indicated as degraded. The purpose of this study was to identify the morphology, composition, abundance of bivalve…
The number of antioxidant activity test methods can provide diverse test results. Commonly used methods include DPPH, ABTS, and FRAP methods. The study was conducted in September-December 2022 using samples from the gastropod and crustacean classes. Test solutions that have been made according to their respective concentrations are measured using a UV-Vis spectrophotometer, then calculated the …
