Abstract

Haliclona sp. is a genus of demosponges in the family Chalinidae. Demospongiae are a type of sponge that lives in marine environments and is known for its unique, often branching skeletal structure. The use of antibiotics has led to the selection of pathogenic microorganisms in humans that are more resistant to many types of drugs, resulting in poorer treatment outcomes in cases of infection. Bacteria can become resistant to antibiotics due to improper dosing, inaccurate diagnosis, and inappropriate use of antibiotics against the causative bacteria. This study aims to determine the antimicrobial activity of the methanol extract of Haliclona sp. as an inhibitor of pathogenic microbes. This research employs a descriptive method with antagonistic testing. The results of the methanol extraction process of the symbiotic bacteria in Haliclona sp. produced a thick, dark brown extract. The results of the antagonistic test showed that the clear zones formed on the three test microbes were categorized as strong.

Abstract

Yayasan Ekosistem Lestari (YEL) in Bahorok Research Station in Bahorok Sub-district, Langkat District, is a very important location for this work. The hilly terrain of the area provides a beautiful landscape and varied flora and fauna with the main attraction being the corpse flower (Amorphophallus sp). With a preserved natural environment and unique ecological features, this research station allows other parties to participate in protecting the area in various conservation campaign, one of which is the installation/establishment of conservation information boards. Conservation information boards can raise public awareness about the importance of protecting forests and their natural environment. Information on ecosystems, flora, fauna, management, and the importance of conservation can be conveyed through these information boards. Information boards are widely used as an educational tool for local communities and visitors to the forest at the research station. They can learn about forest ecology, the negative impacts of deforestation, and sustainable ways of utilizing forest resources. They can learn about forest ecology, the negative impacts of deforestation, and sustainable ways of utilizing forest resources. Information boards can also be used to invite community participation in conservation efforts, which is expected to improve the quality of knowledge and understanding of conservation areas for communities, researchers, and tourists. Therefore, the installation/establishment of conservation information boards needs to be carried out at Bahorok Research Station, Batu Katak as one of the campaign and solutions to maintain the natural conditions in the forest and river.
