Over the last few decades, tremendous strides have been made to reduce the incidence and mortality of cervical cancer by implementing a variety of prevention and treatment strategies. The aim of writing scientific articles is to find new anticancer compounds, which are very important for the treatment of cancer from seaweed, because seaweed is one of the largest marine products sources of active chemical metabolites. The literature search used keywords, Sargassum sp., cervical cancer, HPV, cervical anticancer drugs. The method of collecting literature uses an electronic data base: PubMed, Web of Science, Science Direct, Elsevier, Springer, Google and Google Scholar. The results obtained were mechanism of anticancer compounds against viruses, cytotoxic activity of seaweed against HeLa cells and several types of anticancer drugs. It can be concluded that Sargassum sp. has cytotoxic activity against HeLa cells, so that it can be used as a source of cervical anticancer drugs. Seaweed Sargassum sp. which grows abundantly in Indonesia can be used in medicine to reduce the rate of cases and deaths from cancer.

However, there still needs to be more research that scientifically discusses its medicinal effects. This study evaluates the antimicrobial properties and cytotoxicity of several locally made Minyak Sumbawa in Sumbawa Regency, West Nusa Tenggara, Indonesia. Minyak Sumbawa from Batu Lanteh (BTL) showed the highest antimicrobial properties against Salmonella thypi, Listeria monocytogenes, Escherichia coli, Staphylococcus aureus compared to those from Lunyuk (LNK), Pernek (PRN), Taliwang (TLW), Utan (UTN) and from Sumbawa Besar (SBW). In contrast, Minyak Sumbawa from Labuan Badas (BDS) has the highest activity against Staphylococcus epidermidis. Using the BSLT method, all samples showed low toxicity. The result showed that Minyak Sumbawa has various activit...

The ecological condition of the Tiu Kele river is an ideal environment for Stiphodon fish to live and breed. Therefore, this study focused on identifying the species of Stiphodon sp. (Gobiidae), whose presence has not been recorded in West Nusa Tenggara. There is still no literature study related to the Gobiidae family, especially the genus Stiphodon in the waters of the Tiu Kele river, which makes this research very important to do. This research was conducted from September 13 to October 13, 2021, in Tiu Kele river, Marente village, Sumbawa. The tools used are net, dipper, aquarium, sampling tubes, thermometer, pH meter, and camera, while the material used is 96% alcohol for specimen preparation. The identification results stated that Stiphodon atropurpureus had clearly visible characteristics. It had a bright blue body from th...

This rare finding represents the first-ever known record of F. oxyrhyncha in Malaysian waters, and only the fourth record in Southeast Asia besides former records of F. oxyrhyncha from Thailand, Cambodia, and Indonesia. Further study and monitoring is needed to asses the possibility of the importance of Pahang River as habitat of F. oxyrhyncha.

One that has the potential for mangrove development is Dusun Prajak, located in the Saleh bay area which is directly adjacent to the Moyo Tambora biosphere zone that has a major influence on the preservation of marine natural resources such as coral and whale sharks. The purpose is to provide skill in making natural dyes made from mangroves to community. The method is observation, interviews, practice and assistance with the Participatory Rural Appraisal (PRA) approach. Furtermore, mentoring and evaluation are carried out. The survey result show that weaving based on natural dyes from mangroves has never been done, so it is important to carry out demonstrations of making mangrove dyes. The training program received high appreciation from the community because it was uniqe and hope that program would continue and community would be assisted.

This finding is considered as a first inland record of C. leucas in Celebes, and fourth inland records in Indonesia after Papua, Sumatra and Borneo. Monitoring is needed to asses the possibility of Celebes as a migration route and breeding ground of C. leucas.

In the present paper, we reported on the presence of R. baliensis, which was collected from several new rivers in Java and East Lesser Sunda Islands. The specimen was identified as R. baliensisbased on the number of scales on the lateral line 26 and on the predorsal 12;the upper head and body are light brown while the lower jaw and belly are silver; mid-lateral stripe from opercle to caudal base light blue; dorsal, caudal, and anal fins yellowish; and pectoral and ventral fins hyaline. The paper also showed the current distribution range of this species. The new records of native freshwater fish are important contributions to understanding species diversity and biogeography.

S. auxilimentus is amphidromous that live in both freshwater and marine environments. This species is currently listed as Vulnerable (VU) within the IUCN Red List Status. The specimen was identified as male S. auxilimentus based on the coloration of the preserved specimen: background yellowish; scale edges brown; posterior flanks and caudal peduncle orange; first dorsal fin black, second dorsal fin dusky black; pectoral fin slightly brown; ventral fin slightly dusky; anal fin blackish; caudal fin dusky brown. Specific morphological features were as follows: the base of the first dorsal fin was not connected to the second dorsal fin base; distance between the base of first and second dorsal fin was generally less than half of eye diameter; ventral fin rays were fused to belly only between fifth rays; posterior margin of caudal fins rays was rounded; scales were all ctenoid; scales appeared on the caudal peduncle, and between anal and second dorsal fins; anterior to which, scales became widely spaced and did not imbricate. Meristic characters were as follows: first dorsal fin rays VI; second dorsal fin rays I+9; ventral fin rays I+5; pectoralfin rays 14; anal-fin rays I+9; caudal-fin rays 13; scales in lateral series 13; scales in zigzag series 7; scales in transverse series backward 7; scales in transerves series forward 4. This finding is considered the first record in Sulawesi and the fifth from Indonesian waters after findings in Halmahera, Java, Bali and Lombok. This record enhances the understanding of the distribution of S. auxilimentus in Indonesian waters. Monitoring is needed to assess the possibility of Sangihe Island being a growth ground, spawning ground, and/or on the migration route of S. auxilimentus. In the Laine waterfall, Sangihe island, freshwater conditions were as follows: salinity 3.5 psu, temperature 23-25°C, and dissolved oxygen 7.7-9.2 mg/l, which were ideal habitat for S. auxilimentus. S. auxilimentus from Sangihe Island, had 0.000 genetic distance than from S. auxilimentus from Bali, while the next closest genetic distance was S. zosterophorus at genetic distance of 0.090. In addition to onsite conservation, domestication programs are needed to increase commercial availability without depending on natural catches.
