Sponge organisms produce bioactive compounds that are toxic as a means of self-defense. The compound is known to have the potential as an antibacterial and anti-UV which can absorb sunlight with the potential to be used as a material for making sunscreen. The purpose of this study was to obtain antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria and anti-UV activity from crude extracts and sponges fractions. The antibacterial test done by agar diffusion method (Kirby and Bauer diffusion disc) and the crude extract and the active fraction of antibacterial compounds were tested in a UV spectrophotometer to see its anti-UV activity. As a result, 4 species of sponges were extracted and partitioned into water fractions, methanol fractions, and n-hexane fractions. All samples were tested for antibacterial activity and the results showed antibacterial activity against S. aureus by Plakortis sp. in crude extract (9 mm) and water fraction (8.6 mm), Agelas sp. in crude extract (7 mm) and in E. coli bacteria shown by Plakortis sp. in crude extract (12.6 mm) and water fraction (9 mm), Liosina sp. in the water fraction (7.6 mm), Haliclona sp. in the water fraction (8 mm) and Agelassp. in crude extract (10.3 mm). Crude extracts and water fractions were tested using a UV spectrophotometer for anti-UV testing, the results showed that crude extract and all the water fractions of four species sponge could absorb UV-B (λ 290-320 nm) and UV-A (λ 320-400 nm).Keywords: sponges, antibacterial, partition, anti-UV

Marine bacteria have a lot of potential in exploring the enzyme that can be developed, such as a producer of proteorhodopsin, act as hydrocarbon chlorlastic and can degrade oil. This study aims to obtain isolates and can characterize the bacterial morphology. Malalayang Waters is one of the marine bacterial habitats that has potential area to be studied. This study aims to isolate marine bacteria from Malalayang Waters. These marine bacteria first were diluted into sea water before they were grown on Nutrient Agar (NA).

The purpose of this study was to determine the type, dimensions and composition of nematocytes in Scleractinia, Acropora florida and Acropora divaricata. This research was conducted in South Motandoi Beach, East Pinolosian District, South Bolaang Mongondow Regency, North Sulawesi for five (5) months; from February to June 2019. The method of this research was observation using student-t statistical data analysis. Microbasic p-Mastigophore type-II (MpM-II) and Holotricous isorhiza (HI), while A. divaricata only has type-II Microbasic p-Mastigophore (MpM-II) nematocytes. The nematocytes dimension showed an average capsule length of MpM II in A. florida of was 262.32 µm and A. divaricata was 125.15 µm, mean capsule width of MPM II in A. florida was 67.01 µm and A. divaricata was 31.95 µm, and the average length of mpM II on A. florida was 154.44 µm, and A. divaricata was 70.97 µm. Nematocytes composition showed that MPM II in A. florida was 95.56% and HI was 4.44%, while the composition of MPM II nematocytes in A. divaricata was 100% and HI was 0%. Student t-test showed that the ratio of 2 average values of capsule length, capsule width, and MPM II stem length from two populations of A. florida and A. divaricata were not significantly different (P> 0.05). It can be concluded that both types of A. florida and A. divaricata corals have different types and composition of nematocytes however their size dimensions are not significantly different. Further studies are important to examine genetic and environmental factors to find out how much the kinship relationship between the two types of those coral.Keywords: Acropora florida, Acropora divaricata, HI, Scleractinia coral, MpM II, nematocytes

ABSTRACTBioactive compounds that are suspected of having anticancer activity are first tested for activity by means of a toxicity test. The purpose of this test is to obtain data on the ability of the activity of a bioactive compound to kill cells at small doses so as to obtain a lethal concentration or lethal data. These two measurements are often called LC50 or LD50, concentrations that can kill 50% of test animals. This study aims to test the cytotoxic activity of Thalassia hemprichii seagrass extract using the Brine Shrimp Lethality Test (BSLT) method.The results of the study showed that the mortality of Artemia salina larvae was influenced by the concentration of the test, meaning that the higher the concentration the more test animals died. Furthermore, the results of the probit analysis contained the toxicity activity of bio active compounds from seagrasses where the LC50 was 3.95 mg / l. A substance is declared to have the potential for cytotoxic activity if it has a value of LC50 at concentrations <1000 ppm for extracts and at concentrations <30 ppm for a compound. Keywords: Cytotoxic Activity, Thalassia hemprichii, Brine shrimp Lethality Test (BSLT)

Coral reefs are coastal ecosystems with the highest level of diversity. Corals are invertebrates that are included in the Phylum Coelenterata (hollow animal) or Cnidaria. Whereas coral reefs are a collection of millions of polyps. Natural phenomena and various anthropogenic activities threaten the health and presence of Mantehage Island coral reefs and the lack of information about the health conditions of coral reefs on Mantehage Island. The purpose of this study is to determine the condition of coral reefs andto provide baselines data on Mantehage Island. Data collection was done by using UPT method (Underwater Photo Transect). Underwater Photo Transect carried out by underwater shooting using a digital camera that was shielded (housing). Image analysis were done using the CPCe software (Coral Point Count with Excel extensions). The results of coral reef health conditions at four stations on Mantehage Island shows, coral reef cover at each station as follows, station 1 (one) 53.00% were in good condition, station 2 (two) 25.40% were in a moderate condition, station 3 (three) 16.49% were in poor condition, and station 4 (four) 42.07% were in a moderate condition. From the four stations, the condition of Mantehage Island's coral reefs were in the moderate category with a percentage of 34.24%.Keywords:. Mantehage Island, Terumbu Karang, UPT, CPCe

This study is intended to find out the fish that are cultured into the mangrove area of Tasik Ria beach, Mokupa, Minahasa Regency. Fish is obtained through gill jarring at high tide. The fish that were identified were Archamia fucata, Lutjanus fulvus, Lutjanus eherenbergii, Lethrinus ornatus, Scolopsis lineate, Sargocentron diadema, Epinephelus merra and Scorpaenopsis oxycephala. The fish are generally carnivorous, and are nocturnal.Key words: Tasik Ria Beach, the fishes, carnivorous, mangroves

Bacteria are found to be highly associated with various marine organisms, such as sponges. Sponges are known as the product of bioactive compounds. However, some of the compounds produced by sponges are obtained by the simbion-bacteria. Therefore this situation enables sponges simbion bacteria to play a major role in producing bioactive compounds that have been isolated from the sponge. The purpose of this study is to isolate and determine the characteristics of morphology of spongy simbion bacteria resembling Cribochalina sp, which was taken from Malalayang waters, North Sulawesi. Sponge simbion bacteria grow on NB media. Initially, a free-breeding colony was being done before bacteria were accrued in the NA media by 2% sponge broth (patent SID201906301) by means of Strike Plate methods. Based on to this study we had isolate five spongy simbion bacteria that resembling the Cribochalina sp. All five of these isolations have different characteristics of morphology in terms of color, shape, size, and elevation. Keywords : bacteria, isolation, simbionts, sponges

The octopus in Manado language is called Boboca, while the local Talaud community is called Urrita. Octopus is used as food and bait. Information on octopus biology needs to be known as basic information in the management of octopus resources. This study aims to identify and provide information on octopus habitat in the waters of Salibabu. Collecting specimens using arrows (jubi). The morphology of the example octopus is identified as Octopus cyanea Gray, 1849. In the arms of the octopus there are white-colored spots. On the left and right side of the crown of the arm are two false eyes (ocellus). On the face of the ventral arm is a dark pole pattern above the pale or creamy base color. Characteristics of female morphomes generally have a larger size compared to males. Specimen habitats are found outside the nest at night and in the nest during the day time.Keywoeds: Octopus, Biology, Identify, Morphology, Morphometric, Habitat
