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

Sigi Regency in 2019 has been a flood disaster that submerged several villages around it and brought mud and wood from around the river. The study aims to spatially analyze the spread of flood-prone zones and their causes in Sigi Regency. Spatial analysis method is used in the result data using scoring and weighting methods in five map parameters namely slope, soil type, rainfall, drainage and land cover. From the results of spatial analysis it is known that the distribution of the occurrence of flood-prone zones there are 5 parameters namely not prone to 51.77%, somewhat prone to 28.14%, quite prone to 9.39%, prone to 6.92% and very prone to 3.78%. The main cause of flooding is that changes in land cover each year are increasing and reducing vegetation cover will cause rain water to run off directly to the soil.Keywords: Map parameters, flood-prone zones, changes in land cover, spatial analysis.
