Abstract

Sago palm (Metroxylon sagu), a tropical plant that has functioned as a conservation plant. Sago can withstand rainwater with springs that appear around the sago stand. This plant is resistant to climate change because sago roots have a hydrological function to regulate the arrangement of water sources in the soil so that water quality is maintained and sago plants continue to produce. However, currently, the existence of sago in its natural habitat is under threat of extinction due to the clearing of sago forest which is converted into residential land, public facilities and infrastructure, rice fields, and over exploitation. The purpose of this study was to determine the regeneration potential and dispersal pattern of sago in Bajo Barat District, Luwu Regency. The method used in this research is a purposive sampling technique (nonrandom sampling). Starting from a field survey were to determine the point of sago land where data is taken, make a circular plot with a size of 20 meters with a total plot of 31 plots, taking the required data. The data were analyzed by calculating the number of individuals and density to determine the regeneration potential. But, the spatial distrubtion pattern used the Morisita Index and Dispersion Index. The results showed that the regeneration potential of sago plants in Sampean Village and Kadong-Kadong Village with density analysis experienced adequate regeneration growth (fair category). The dispersal pattern of sago palm in Sampean Village is dominated clumped by using the analysis of Morisita index and Dispersion index, while the seedling phase indicates a uniform distribution pattern. However, the dispersal pattern of sago shows the diffrent between Morisita index (uniform) and Dipersion index (clumped) in Kadong-kadong Village. To improve the existence of sago plant communities in their natural habitats, it is necessary to plant or cultivate using local types of sago plants, as well as conservation of sago from the village government and local communities.
