BIOMASSA DAN KARBON TUMBUHAN BAWAH SEKITAR DANAU TAMBING PADA KAWASAN TAMAN NASIONAL LORE LINDU
Get PDFGenerally, at the growth phase of the forest, plants, for example ground plant can absorb CO2more higher than climax forest. This study was aimed to determine biomass and ground plants carbon around Tambing lake. Research was carried out in Tambing lake, Lore Lindu National Park area, from August through October 2013. Quantifying biomass was done by destructive method by collecting all ground plant samples in plots. Ten plots (1m x 1m) were established in south, east, north, and west part of the lake with distance between the plot is 10 m. The results showed that the biomass average were 0.26 ton ha-1, 0.48 ton ha-1, 1.12 ton ha-1and 0.93 ton ha-1 in south, east, north and west part of the Tambing lake, respectively. Hence, the average number of carbon were 0.12 ton ha-1, 0.22 ton ha-1, 0.52 ton ha-1 and 0.44 ton ha-1 in south, east, north and west part of the Tambing lake, respectively.

EFEKTIVITAS BAHAN PENGAWET ALAMI DARI TANAMAN TEMBELEKAN (Lantana camara L) PADA BEBERAPA JENIS KAYU TERHADAP SERANGAN RAYAP TANAH (Coptotermes sp.)
Get PDFMany favorable properties of wood are available in almost all parts of the world, easily obtained in different shapes and sizes, relatively easy to process, as well as very decorative appearance. However, wood also has a weakness that could be damaged by a variety of factors either biological, physical, mechanical or chemical. In reality, the main factors causing damage to the wood are fungi, bacteria, insects and marine animals (marine borer). The organisms might damage the wood because they make as a shelter or as feed. Therefore, there should be conducted wood preservation to overcome the unfavorable properties of the woods. Wood preservation aims to extend the use of low-class durability of timber species such as Bayur (Pterospermum sp), Durian (Durio zibethinus) and Benuang (Octomeles sumatrana Miq). This study aimed at determining the effectiveness of a natural preservative tembelekan (Lantana camara L). The research was conducted at the Forestry Sciences Laboratory, Department of Forestry, Forestry Faculty, Tadulako University and Talise Mantikulore Sub-district, started from May to July 2013. The study was designed with the method of completely randomized design (CRD) with three wood species treatment, namely bayur, durian and benuang. Each was preserved with a natural preservatives of tembelekan extract with a concentraation of 13,04%. There were 10 samples of each type of wood, consisting of 5 test samples preserved and 5 controls (without preserrvatives). There were 30 test samples. The parameters observed were preservative effectiveness of the sample weight after feeding on soil termites. The study shows that highest natural preservative effectiveness on benuang wood was preserved with the sample weight loss of 2,25% and the lowest on bayur wood was preserved with the sample weight loss of 3,47% when they were compared with the control sample (without preservative). Using tembelekan extract might increase wood resistance to soil termite attacks. Keywords: Captotermes sp, Durio zibethinus, Lantana camara L, Octomeles sumatrana Miq, tembelekan

Get PDFThis research aimed to know carbon stock in the soil around Tambing Lake, Lore Lindu National Park area, Sedoa village, Lore Utara district, Poso regency, Central Sulawesi. The collection of soils samples was conducted in June-August, 2013. This study uses survey method two lines with size 20 m x 100 m were place in two sites, in the Lake buffer zone (distance 10 m from the lake shore) and outside of the Lake buffer zone (distance 150 m from the lake shore). Soil sampling was done in three depth layers ; 0-10 cm, 10-20 cm and 20-30 cm. Soil samples was divided into two types, namely undisturbed and disturbed soil. The soil carbon was estimated by analyzing bulk density and soil organic carbon by Walkley-Black method. The results showed that the average carbon stock in the soil around buffer zone of Tambing Lake were 130.95 ton ha-1, 62.02 ton ha-1, 42.71 ton ha-1, in the depth layer 0-10 cm, 10-20 cm and 20-30 cm, respectively. Further, at out buffer zone, the average carbon stock in the soil were 144.51 ton ha-1, 53.55 ton ha-1, 20.71 ton ha-1, respectively. Keywords : Soil carbon, Tambing Lake, Lore Lindu National Par

This study was aimed to know direct and indirect benefits of mangrove forest by analyze and quantify its value to Indonesian currency (IDR). The study was conducted at Sausu Peore village, Sausu sub-district, Parigi Moutong regency, Central Sulawesi, from March through May 2014. The method used in this study was based on the market price. Respondents were selected by purposive sampling method. Identification and quantification of the use natural resources was done by assessment on the market and replacement price. The results showed that direct benefits of the mangrove forests in this area are firewoods, wood as construction materials, fishs, shellfish, crabs, and bats, while indirects benefits of the mangrove forests is as a buffer on coastal aberration. The economic value of direct benefits was IDR. 513,499,753, while the value of indirect benefits was IDR. 499,655,240, so the total value of all benefits was IDR.1,013,164,993.

Get PDFNowadays, utilization ofnon-durable wood species in Indonesia is one alternative to meet the needs ofthe wood. Use natural preservatives such as Orthosiphon aristatus in natural wood preservation processis highly recommended as environmentally friendly.This study was aimed to determine retention and the effects of Orthosiphon aristatus leaves extracts as preservation material of Durio zibethinus wood on the Coptotermes sp. Attacks. Regency and the laboratory of Forestry Science, Tadulako University, from May to June 2013. The study was using completely randomized design with factorial pattern. The treatment of study was applying two factors. First, concentration of Orthosiphon aristatus extracts with three levels, namely; 9.09% (A1), 16,67% (A2), and 23,07% (A3). Second, Dipping time with three levels,namely: 1 day (B1), 3 days (B2), and 5 days (B3). The results showed that the highest retention value (3,538g/cm3) was achieved by the combination treatment between concentration 23,07% and dipping time 5 days (A3B3) while the lowest retention value (0,562g/cm3) was achieved by the combination treatment between concentration 9,09% and dipping time 1 day (A1B1). Hence, the lowest effectivity of preservation materials indicated by the highest weight loss,was achieved by A1B1 combination treatment (3,37%) while the lowest (highest effectivity) was achieved by (A3B3) combination treatment (1,88%).
