Abstract

The purpose of this research was to determine the condition of mangrove forest habitat in Membuke village, Poso Pesisir Utara District, Poso regency.  The method of this research is descriptive. The location for sampling soil was determined by purposive sampling method. Based on field observations, it was found that there were four types of stands, namely Rhizophora apiculata, Sonneratia alba, Avicennia marina and Xylocarpus granatum. Soil samples were taken at each of stands and analyzed in Laboratory of agricultural faculty, Tadulako University. The results of the research in the field and on the analysis of eight parameters observed showed that soil pH ranged from 5.33 to 6.29, the dominant soil color is black. soil texture from the four observation points was dominated clayey loam to sandy clay, the salinity ranged 26,9 ppt to 31,6 ppt, water pH ranged from 5.93 to 6.52, Nitrogen (N-total) ranged 0.33% to 0.39%, Phosphorus (P-total) ranged 25.72 (mg / 100g)  to 53.76 (mg / 100g). The KTK value ranged 15,20 to 28.76 (cmol (+) kg-1). The depth of the mud in the mangrove forests in four different observation site were different, in which the depth of mud under Rhizophora stand was 45 cm, under Rhizophora was 30 cm, under avicenia marinna stand was 41 cm, and under Xylicarpur Granatum stands have very deep mud that was 143 cm.

Abstract

Lore Lindu National Park (LLNP) is one of Biosphere Reserves, the habitat of various types of potential medicinal plants as an asset of biodiversity that should be managed properly for the welfare of the local communities and the ecosystem sustainability. The objective of this study was to determine the potential of medicinal plants in the area of Lore Lindu National Park, precisely in Namo Village, Kulawi Sub-district, Sigi District. Continuous strip sampling was opted as the research method by carrying out purposive sampling in the site where medicinal plants were discovered firstly, by establishing 5 (five) lines with a length of 100 m per line, each line consisted of 4 (four) plots, the distance between the line was 25 m. Total plots were 20 plots with 20 m x 20 m in size per plot. The study found out there were 18 species of medicinal plants that consisted of 14 families in Namo Village, Kulawi, Sigi. The potential of medicinal plants at the tree level is 43 stems / Ha, poles are 40 stems / Ha, sapling are 54 stems / Ha and seedlings and herbs are 296 stems / Ha. Medicinal plant dominated the area at the tree level was Pterospermum celebicum Miq. with Importance Value Index (IVI) of 97.64%, at the pole level of was Huka (Gnetum gnemon L.) with IVI of 84.64%, at the sapling level of Huka (Gnetum gnemon L.) with IVI of 72.69%, and the seedlings and understorey level was Naho (Pandanus sp.) with IVI of 19.50%.
