Abstract

Mantangan (Merremia peltata (L.) Merr.) is a woody liana. Nowadays, it has become invasive in Bukit Barisan Selatan National Park. The objectives of this research were to analyze: 1) effect of light intensity on the growth of mantangan in natural and artificial shade, 2) effect of sand addition to the soil media and trimming on the growth rate of mantangan. Forest profile was made at the field in three locations with three light intensity levels: low, moderate, and high. A completely randomized design by three factors: shade, soil media and trimming were used. Parameters measured were stem length, leaf and buds number, fresh and dry weight. Forest profile analysis showed that high light intensity forest was dominated bay mantangan. In contrast, growth of mantangan was inhibited in low light intensity (75% shade), with lower dry weight (1.50 g). Soil media and trimming did not affect significantly on growth of mantangan.

Abstract

Indonesia is a high-abundance tropical forests country. It plays a very important role for world life because of its species richness than others. One of the forest resources in Indonesia is indigenous forests. Indonesia is rich of local wisdom such as that possessed by indigenous peoples. Indigenous peoples have a potential of the biological resources conservation. As a sustainable management tradition, communities around indigenous forest also have the efforts to preserve the forest.  The data collection of community knowledge about plants was conducted by interviews and direct-field observation. Data were analyzed using index of cultural significance. The results showed that there are 48 species of plants utilized by communities in Hiang Indigenous Forest, 27 species are used as firewoods, 15 species as building materials, 7 species as medicinal plants, 6 species as traditional handicraft ingredients and 4 species as secondary foods and traditional ritual materials. Most of widely-used plants by the community are Altingia excels, and Styrax benzoin is used as incense in a traditional ritual.

Abstract

The study aims to know the productivity of litter and litter decomposition rate in karst ecosystem. This study was conducted on three altitude of 200 meter above sea level (masl), 250 masl and 300 masl in karst ecosystem at Gunung Cibodas, Ciampea, Bogor. Litter productivity measurement performed using litter-trap method and litter-bag method was used to know the rate of decomposition. Litter productivity measurement results showed that the highest total of litter productivity measurement results was on altitude of 200 masl (90.452 tons/ha/year) and the lowest was on altitude of 300 masl (25.440 tons/ha/year). The litter productivity of leaves (81.425 ton/ha/year) showed the highest result than twigs (16.839 ton/ha/year), as well as flowers and fruits (27.839 ton/ha/year). The rate of decomposition was influenced by rainfall. The decomposition rate and the decrease of litter dry weight on altitude of 250 masl was faster than on the altitude of 200 masl and 300 masl. The dry weight was positively correlated to the rate of decomposition. The lower of dry weight would affect the rate of decomposition become slower. The average of litter C/N ratio were ranged from 28.024%--28.716% and categorized as moderate (>25). The finding indicate that the rate of decomposition in karst ecosystem at Gunung Cibodas was slow and based on C/N ratio of litter showed the mineralization process was also slow.
