Abstract

Mangroves are forest vegetation that grows between the tidal lines, so mangrove forests are also called tidal forests. The existence of mangrove forests in the ecosystem is very important because it has ecological and economic potential. The location of the mangrove ecosystem in a transitional area between sea and land areas causes mangroves to frequently experience disturbance for human purposes and results in mangrove areas experiencing damage and land narrowing which has an impact on decreasing their diversity. This research aims to analyze the structure of the mangrove community in the research area. The method used in this research is the quadratic method (Quadrat Sampling Technique) by creating 6 plots facing each other. Observation of mangrove vegetation uses a plot measuring 10 x 10 meters for trees, 5 x 5 meters for saplings and 2 x 2 meters for seedlings. The results that can be concluded from this research are that the mangrove forest community in Teluk Buo consists of Rizophora apiculata, Lumnitzera littorea, Brugeira gymnorhiza, Setaria palmifolia, Euterpe oleracea mart, Nypa Fruticans, and Bruguiera cylindrical. The Rhizophora apiculata species dominates in the study area, characterized by the highest importance at all growth levels. INP at tree level was 166%, sapling 219% and seedling 127%. The diversity index (H') value in the study area is low (1.749) with a high level of uniformity (0.8986).

Abstract

Amorphophallus has 176 species spread throughout the world, 25 of which are found in Indonesia. Of the 25 species found in Indonesia, 8 of them are endemic to Sumatra. One type of Amorphophallus found on the island of Sumatra is Amorphophallus titanum, whose survival in its natural habitat is threatened by deforestation and forest degradation. As an endemic plant, A. titanum is also more vulnerable to anthropogenic threats and environmental change, and therefore faces a greater risk of extinction than more widespread species. To prevent species extinction and as a form of biodiversity conservation, information is needed that presents the population status of A. titanum in its natural habitat. This article aims to provide information about the population of corpse flowers (Amorphophallus titanum Becc) in Sumatra. The research method used is a literature review. Data was obtained from journals and articles published from 2005 to 2023. Based on research conducted, it is known that A. titanum is often found in Bengkulu, Lampung, Jambi, North Sumatra and West Sumatra. The highest population of A. titanum is in Muara Hemat Village, South Kerinci Resort, Kerinci Seblat National Park, Jambi, with a total of 83 individuals. In Bengkulu, A. titanum is found in several locations; in KHDTK (Forest Areas with Special Purposes) as many as 64 individuals. At Ketapang Water, Jufi Hill and Datar Lebar Waterfall there were 56 individuals. In the Mount IV Kepahiang Nature Reserve there are 56 individuals. In Tebat Monok, Air Selimang and Palak Siring the number is 52 individuals. Meanwhile in North Sumatra, specifically in the Sibolangit Nature Reserve, Sibolangit Nature Reserve, Dolok Sipirok Nature Reserve, and Namo Suro Baru Village, 32 individuals were found. In Palupuah, Agam Regency, and South Solok, West Sumatra, there are 24 individuals, and also in the Liwa Botanical Gardens, Lampung, there are 4 individuals.
