Abstract

Ecological research for inventory of plant and vegetation structure was conducted at Nahuang forest, Muller Mountains, Central Kalimantan. Seven plots of observation of 20 x 50 m2 were established based on the existing altitude. The result show that for tree category Shorea, Vatica, and Dipterocarpus are the dominant taxa while for seedling and sapling Callophyllum, Sterculia, Syzygium, and Gluta are the dominant genera. The density of tree is relatively high i.e. 557/ha whereas the average of bole diameter is low. There are only 7 trees having bole diameter more than 60 cm. This result is important for management authority as a basic knowledge to protect forest from destructive activities.Keywords : Vegetation structure, Dipterocarpaceae forest inventory, Central Kalimantan virgin forest

Abstract

The research were carried out to study the potency of Salvinia molesta D.S. Mitchell (Kiambang), Limnocharis flava (L.) Buchenau (Genjer) and Monochoria vaginalis (Burm.f.) Presl (Eceng) for Hg phytoextraction on paddy field contaminated with Hg from illegal mining. The plants were grown on contaminated media from paddy field in Pongkor (68.269 ppm Hg) added by NPK fertilizer (0, 3 and 6 g/pot) and ammonium thiosulphate chelating agent (0, 20 ppm). The result showed that the growth of kiambang,eceng, genjer and padi are significantly different. Chelating agent did not significantly affect the plant growth, meanwhile fertilizer significantly affected the plant growth. Thetreatments resulted in different Hg concentration in the plants. Fertilizer increased plant biomass and so plant Hg content since Hg contents is a function of total biomass and Hg concentration. It can be concluded that based on the criteria of accumulator plant,kiambang is the most potentially Hg accumulator followed by genjer and eceng.Key words: Phytoextraction, Hg, Salvinia molesta, Limnocharis flava, Monochoriavaginalis
