Abstract

Callyspongia sp. is one type of sea sponge that produces secondary metabolites in the form of steroids, alkaloids, flavonoids, and terpenoids which can be used as antibacterial agents. This reseach aims to determine whether or not there is an inhibitory power of sea sponge extract Callyspongia sp. on the growth of bacterial isolates on Eucheuma cottonii seaweed that is infected by ice-ice disease. This type of research is an experimental laboratory. Extract of Callyspongia sp. is the result of Callyspongia sp. extraction which has been dried and then macerated using a polar ethanol solvent. Inhibition test with the modified Kirby-Bauer method used wells to measure the zone of inhibition formed by the extract of the Callyspongia sp. The test was carried out to observe the presence or absence of an inhibition zone of Callyspongia sp. extract against bacterial isolates (Isolates I, II and III) that is infected by seaweed that is infected by ice-ice disease after 24 hours of incubation. The results showed that an inhibition zone was formed in bacterial isolates. Treatment with extracts of Callyspongia sp. shows the diameter of the highest inhibition zone that is 16.67 mm which is classified as a strong inhibitory force, so that Callysponia sp. extract has the potential in overcoming ice-ice in Eucheuma cottonii seaweed.

Abstract

Begonia kelimutuensis is an endemic species of Kelimutu National Park, Ende Regency, East Nusa Tenggara. Since it was designated as an endemic plant, this species has become one of the attractions for visitors to the Kelimutu National Park. However, research studies on this species are not widely known, so further research is needed. This study aims to determine the structure of the vegetation, the composition of plant species in the habitat of Begonia kelimutuensis and the Important Value Index (INP). The research method used is the plotted line method, with 20m x 20m plots used to collect tree species data, 10m x 10m plots used to collect pole type data, 5m x 5m sample plots used to collect sapling type data, and sample plots The size of 2m x 2m was used to collect data on the type of seedling with a distance between plots of 20m, which was placed along the observation path. Data analysis was carried out using the vegetation analysis method that calculates frequency, density, dominance, relative frequency, relative density, relative dominance, and Important Value Index (INP). The results showed that the composition of tree species in this area consisted of 44 species with a vegetation structure consisting of trees, poles, saplings and seedlings. The highest INP at the seedling level was Suregada sp. by 72.33%; at the sapling level is Suregada sp. by 83.86%; at the pole level is Chyathea contaminans of 79.15%; and at the tree level is Schfflera lucida by 58, 33%.
