Abstract

The Unit X of Protection Forest Management Unit of Central Sulawesi Province with an area of 97,157.66 ha is one of the FMUs in Indonesia for the purpose of sustainable forest management. The FMU located in Poso District has a protected forest area of 68.17% and limited production forest of 31.83%. The objective of the study was to analyze spatial distribution and the number of natural rattan regeneration of the relationship with the habitat condition in protected forests of sub-mountain rain zones. Spatial analysis method used in the data of natural rattan inventory results in 2018 with the help of geographic information system technology. From the analysis result, it is known that the distribution of natural rattan regeneration of three types of rattan (tohiti, symbol and stem) is determined by land cover / vegetation factor, soil type, land system, geology, slope aspect with correlation value (r) 0.93 - 1 (strong positive correlation); other contributing factors are slope class and altitude with correlation value (r) 0.59 – 0.79 (medium positive correlation); while the precipitation is weakly correlated positively with the value (r) 0.16. Of the three types of rattan analyzed, rattan lambang have high adaptability compared to the other two types of rattan (rattan batang and rattan tohiti).Keywords: Natural rattan regeneration, sub-mountains rain zone, spatial analysis.

Abstract

The Bajakah plant (Poikilospermum suaveolens (Blume) Merr) is a plant that grows a lot in the tropics, in Indonesia itself is known for its tropical climate. traditions and community beliefs. Bajakah plants can be found in Sulawesi, to be precise, in Kapiroe Village, Palolo District, Sigi Regency, Central Sulawesi Province. This research was conducted from November to December 2020 for 96% ethanol solvent and continued in March 2021 for n-hexane solvent at the Research Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Tadulako University. The method used in this study was the manufacture of Bajakah leaf powder (Poikilospermum suaveolens (Blume) Merr), analysis of the moisture content of the Bajakah leaf samples, extraction of the Bajakah leaf samples by maceration and identification of the chemical content of the maceration results of the Bajakah leaves using phytochemical tests such as the flavonoid test, test alkaloid, saponin test, tannin test, carotenoid test, terpenoid test and steroid test. The results of the water content of the leaves of bajakah (Poikilospermum suaveolens (Blume) Merr) were 11.26%. The phytochemical test analysis contained in the leaf extract of bajakah (Poikilospermum suaveolens (Blume) Merr) using 96% ethanol solvent is positive for alkaloid compounds, saponins, tannins, terpenoids while for positive n-hexane solvent contains tannins, steroids and carotenoids.Keywords:phytochemical analysis, extract, Poikilospermum suaveolens (Blume) Merr
