Abstract

Sub watershed of Latoma has to be considered as an area of the important regions in South East Sulawesi, because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which has been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Latoma sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Run-off Curve Number (CN) model based on Geographical Information Systems (GIS). The result of the research revealed that the run-off curve number is 70,34. It showed that maximum potential water retention or infiltration rate is 107,10 mm. Restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability objectives. Keywords : Watershed, land use, run-off curve number (CN), GIS

Abstract

The effect of preservative treatment using carbon dioxide as a carrier solvent on wood physical properties and dimensional stability had been observed on three commercial wood species (Agathis sp., Palaquium sp., and Heritiera sp.). For the purpose of the study, wood samples measuring 1,5 (R) x 1,5 (T) x 15 (L) cm were prepared. Treatment was conducted at elevated temperature (50C - 350C) and increased pressure (60 - 80 kgf/cm2) on one occasion with five replicates using two specimens of each wood species for each treatment. The final treatment condition was maintained for three different periods (10, 20, 30 minutes). Results indicated that the physical properties and dimensional stability of the preserved wood were not significantly affected by the application of CO2 impregnation as carrier solvent. Key words: Preservative treatment, Carbon dioxide, Carrier solvent, Wood physical properties, Wood dimensional stability

Abstract

The study aims to determine the distinguishing plant species within a plant community forest in the karst area of Maros-Pangkep. Plots of 20 meters by 20 meters were purposively established on 40 different locations representing proportionally facies of massif, porous, leyered and metamorphosed carbonate rocks. Tree dimensions in terms of height and diameter of trees in every plot were measured. The data were examinated through table method and principal component analysis (PCA). The study indicated that the distiguishing plant species determined by table method, only could diffrenciate between the group of communities over massif, porous rock facies and the group of communities over layered, metamorphosed rock facies. Whereas, determining plant species characteristic by PCA method gave sharper interpretation about the distiguishing plant species of plant communities among massif, porous, layered and matamorphosed rock facies. Keywords: Karst area, South Sulawesi

Abstract

The anatomical characteristics were studied to collect information for wood identification of Gyrinops versteegii from Gorontalo. Anatomical characterisics were determined from microtome sectioned samples and macerated samples. Observation of anatomical structure in accordance to IAWA List included vessel (diameter, height, grouping, frequention, porosity, arrangement, perforation plates, deposits, and pits), rays (type, height, width and frequention), parenchyme, and fiber (diameter, diameter of lumina and wall thickness). The research results obtained are G. versteegii has included phloem, diffuse porous, radial multiple 2-4(7), 90 µm in tangential diameter, 14 per sq.mm, simple perforation plates, intervessel pit alternate and no deposites in vessel. Rays uniseriate, heterocellular and 8,4 rays per mm. Axial parenchyma diffuse or associated with included phloem and there are fusiform parenchyma cells. Intercellular canals absent. This wood has short size and very thin walled fiber. Keywords: Agar wood, wood anatomy, included phloem, G. versteegii

Abstract

A study on the contribution of community forest to the community income in Tana Toraja Regency was implemented with the aim of identifying the community forest contribution to owners income and formulating the effort that can be carried out for enhancing the contribution. As the result, the community forest contribution to owners income is still very low (2.94% in average). Based on analysis result, the potencial revenue of community forest farming in Tana Toraja Regency can be 2.3 larger than the present obtaining revenue. The mentioned potencial revenue can be more increased by developing a more proportional allocation of the revenue to the related farmers (related communities) Key words : Community forest, contribution, community income, forest product and benefit

Abstract

The wood species used in this research was gmelina wood from community forest, Maros Regency and jati wood from community forest, Barru Regency. For objective of the research, parts of the tree were taken a short cut (5 cm) from root, branch and top of the tree. All samples were tested their chemical component (cellulose, hemicellulose, lignin and extractives) and fiber dimensions with it’s derivates fiber. The results showed that root, branch and top of the tree of gmelina wood and jati wood from community forest can be used as a raw material for pulp and papers. Key words: Chemical content, Fiber Dimension, Gmelina Wood, Jati Wood, Community Forest

Abstract

The fiber of sugar-palm tree Arenga pinnata Merr., locally known as ijuk, is frequently harvested after the tree age of 5 years and traditionally used as covering to protect ground-contact wood construction materials against organism attack, particularly subterranean termites. The effectiveness of sufar-palm tree fiber extract of marketed formation using acetone and and hexane againts subterannean termites (Coptotermes sp.) has been observed. The results showed that mortality of termite after 2 weeks is 100% on samples given the sugar-palm tree fiber extract, compared with the mortality of controls (without sugar-palm tree fiber extract) is 7,07% after 3 weeks. The consumption rate of termites opposited with the mortality value, due to the existence of bioactive components or chemical compounds having inhibitor or toxic against termites activities. Key words: Sugar-Palm Tree Fiber, Arenga pinnata, Antitermiticidal activities, Coptotermes sp.
