Abstract

The aim of this research was to determine the anatomy, physical and mechanical properties, drying characteristics and treatability of kemiri wood. The observed paramaters were macroscophic and microscophic characteritics, moisture content, specific grafity, shrinkage, strength properties, drying quality, and the retention and penetration of wood preservative. Tests were run according to IAWA List, SNI and JIS. The heartwood colour is white to yellowish white and it is not clearly demarcated to the sapwood. Wood texture is rather coarse, stright grain, rather rough and rather glossy surface. The vessels are oval, diffuse porous, simple perforation plates. Parenchyma type is incomplete borders to the vessels and short tangential lines. Rays heterocellular are uniseriate and biseriate. Its fiber length is medium long size. Kemiri wood is classifed to strength class IV-III. Retention and penetration of wood preservative after 5 days in cold water treatment was met to SNI standard. The air drying test indicated the need of 8 days to achieve of the moisture content 12,29%. Wood defects due to the air drying test can be occured in the forms of check, bowing, discolouration and blue stain.

Abstract

Nipah (Nypa fruticans Wurmb.) produces sap that can be obtained by tapping process from fruit stem. In fresh condition of nipah sap taste sweet cause of including relatively high of sugar. This liquid is a fertile medium for the growth of microorganisms, so that nipah sap is potentially used as a raw material to produce nata. Nata is a food that classified in food dissert. Experimental of nata fruticans production bold by fermenting process used fresh nipab sap that with sugar in level of 0, 50, 75 and 100 g/l of nipah sup. By using fresh nipah sap that add with sugar in vary level yielded nata fruticans with producing recovery an average of 86.05% (76,52-90,97%). The addition of sugar in the fresh nipah sap is not affect significantly on the producing recovery of nata fruticans. Using fresh nipah sap without sugar addition yielded nata fruticans with producing recovery an average of 83,74%.

Abstract

This paper excamined the anatomical and physical properties of two wood species from West Sulawesi's natural forest, i.e. kambelu (Baccus rolfir Vidal.) and kanduruan (Phoebe cuneata Blurne). The results show that the major anatomical structure of kambelu are reddish brown beurtunod, pink greyish sapwood (2-3 cm in thickness), distinct growth rings, bard, interlocked fiber, moderately fine texture and medium lustrous surface. Wbile, kanduruan anatomical properties includes brawn greyish beartwood, light brown sapwood with 5-7 cm thickness, moderately fine and uneven texture. interlocked fiber and medium lustrous surfaces, slightly slippery, hard, no specific wood pattern and odoserless. The fiber of both wood species are classified long while the cell wall thickness are medium. Both are classified as quality 1 class for pulp and paper. Kambelu and kunduruan wood densities are 0.62 and 0,63 respectively and grouped into strength class of III-1. Shrinkage percentage of kambelu is less than kanduruan wood.

Abstract

In general, pine resin yield is affected by various factors i.e. pine tree species, growing environment and tapping method. This paper studies pine resin tapping yield by drilling method using H₂SO₄ stimulant. Tapping point is designed in the depth of 4, 6 and 8 cm and sloping 25°. Three stimulant concentrations (0, 15%, 30%) were brushed in the tapping point and the treatments were repeated 10 times. Experimental design based on 3 × 3 factorials in completely randomized design. The first factor is the depth of drilling holes, the second factor is the concentration of H₂SO₄ stimulant used and repetition of 10 times. Pine resin yields were analyzed using analysis of variance and further test was conducted by honestly significant difference test. Results show that tapping pine by drilling and stimulant addition produced pine resin between 15.5 to 109.3 g / tree / collection (56.3 g / tree / collection on average) or between 2.6 to 18.2 g / tree / day (9.4 g / tree / day on average). Pine resin yield is significantly influenced by drilling hole depth and H₂SO₄ stimulant concentrations. The deeper the drilling hole, the more pine resin yield, and the higher the concentration of H₂SO₄ stimulant the higher pine resin yield. Pine resin yield of 8 cm tapping depth is 65.96% higher than 4 cm tapping depth, and 30% H₂SO₄ improved the yield by about 56.45%. The largest pine resin yield is achieved from tapping point of 8 cm depth and 30% H₂SO₄ that yiled about 90.7 g / tree / collection in average.

Abstract

Activated charcoal is charcoal product obtained through activating process which possesses better adsorption properties and wider uses than charcoal. The common sources of activated charcoal feedstocks are coal, wood and agricultural by-products such as nutshells and fruitpits. This research was carried out to develop processing technology of cundienut shell activated charcoal. Candlenut shell (Aleurites moluccana Willd) were carbonised in drum kyln to produce charcoal, then the charcoal was activated in electrical retort beating duration of 90 and 120 minuts at temperatur of 550 C, 650 C and 750 C. Properties evalnation were assessed in a accord with the Indonesia National Standard (SNI) 06-3730-1995. Results indicated that the activation treatment bad direct affect on the activated charcoal properties. The activated charcoal that efforded highest adsorption capacity on lodine number of 758,70 mg/g wat optained by steaming activation could meet at temperatur of 750 C. This activated charcoal properties the requirements of SN106-3730-1995,

Abstract

This research was carried out to cocamine hatic wood properties (anatomical structure, physical and mechanical properties and machining aspect of three lesser-known species from natural forest in Sulawesi ie. sama-sama (Ponteria firma Bachni), palade (Aglaia sp.) and kumsa batu (Manilkaru merrilliana H.J.L.). Appropirate pood utulization war determined by considering their basic properties and uses which the locally community bave currently end Results revealed that sama-sama beartwood is dark brown to black with irregular black lines bandi; rather fine texture and glasry surface; rather beary; moderate in dimenzional shrinkage; strenght class IV-III; good grade for machinery, fiber grade is good for pulp/paper manufacture; probable utilization are for light construction material in bouse building and certain ship omponents, peeling venter, glulam, pallet, pulp and paper. Palado beartwood is light brown to grayish brown colour, straight grain; rather fine tecture; rather beavy; moderate in dimensional shrinkage; strenght class III; good grade in machinery, fiber grade is good for pulp/paper manufacture; probable utilization are for light construction material in hours building and certain ship components, cheap furniture, moulding, glaulam, peeling veneer, bandicraft, pulp and paper. Kumna batu beartwood is reddish brown colour, greath rings diffuse and sometimes appeared clear with figures of decurative surface as parallel lines on radial section; grain straight; toctare fine and glosty zarface; remarkably beary, high in dimensional shrinkage; strenght class 11; very good grade in machinery: fiber grade is poor for palp/paper manafactureprobable utilization are for beary construction material in bowse and ship building, vehicular(track bodypower line poles, furniture, moulding, slicing veneer, tool bandies, handicraft and charcoal.
