Thinning on the Growth of Red Jabon Trees (Anthocephallus Macrophyllus) in the Industrial Plantation Forest Area

This study aims to observe the growth of red jabon (Anthocephalus macrophyllus) plants at various thinning intensities. Red jabon is a native Indonesian plant species that have the potential to develop forest plantations and reforestation ex-mining land. The research measured stem diameter and plant height at each thinning intensity. The study results are expected to provide information on the potential of red jabon cultivation and become a recommendation for red jabon wood farmers to improve the quality of company and farmer income. This research is expected to contribute to the development of thinning activities in improving the quality of red jabon tree stands, as well as providing a better understanding of this plant's cultivation and potential benefits. The thinning intensity applied 6 months the growth of Red Jabon trees in the Industrial Plantation Forest Area of PT. Global Citra Lestari showed a significant effect on stem diameter increment, 40% intensity treatment has a promising potential to enhance both stem diameter and height growth

Ethnopharmacology Potentials of Mangrove Bulalo, North Gorontalo

Ethnopharmacology is the study of the practical utilization of mangrove plants which have been used as a source of traditional medicine by people living in certain areas since ancient times for generations. This study aims to determine the diversity of mangrove species as the ethnopharmacology of Bulalo, Kwandang District, North Gorontalo. The research was conducted from March to May 2023. The method used in this study was semi-structured interviews. The results showed that species that have the potential for ethnopharmacology are widely used by local people as traditional medicines. Based on the results of interviews with the local community, of the 14 ethnopharmacological species found in Bulalo Village, 7 species have medicinal properties and have been used as traditional medicines by the community for generations, such as Avicennia alba, Bruguiera gymnorriza, Ceriops decandra, Rhizophora apiculate, Rhizophora mucronate, Rhizophora stylosa, and Sonneratia casseolaris, which has been used as a medicine containing phytochemical compounds such as alkaloids, saponins, terpenoids, flavonoids, and phenols. The parts used in traditional medicine are the fruit, leaves, and sap. The ways to use it include hypertension, hepatitis, asthma, flatulence, recovering energy after giving birth, mouth sores, malaria, dysentery, ulcers, cholera, sore eyes, itching, internal injuries, boils, healing burns, and bruises

STRUKTUR VEGETASI MANGROVE DI PESISIR PANTAI DESA DAMBALO KECAMATAN TOMILITO KABUPATEN GORONTALO UTARA

Mangroves are tropical coastal vegetation communities dominated by several unique tree species that can be affected by tides. Damage to mangrove forests can be caused by two main factors, namely human activity factors and natural factors. The purpose of this study was to analyze the structure of mangrove vegetation by looking at density, frequency, Impact Value Index (IVI) and species diversity (H ') on the coast of Dambalo Village, Tomilito Sub-district, North Gorontalo District. The method used is a combination of the path method and the checkered line method so that measuring squares are created within the paths. The results showed that the number of mangrove diversity was 11 species, with the Importance Value Index at the tree level of the Rhizophora apiculata species having the highest value of 61.28% and the seedling phase with the same species Rhizophora apiculata having the highest index of importance of 29.80%. The main conclusion from this research is that the mangrove vegetation structure has an abundant level of species diversity. This shows that the index of species diversity in mangrove vegetation is H '= 2.2692 that species diversity is abundant
