Abstract

Illipe nut in Indonesia serves as one of the essential export commodities from non-wood forest products group. Illipe nut through the extraction can be processed into high-economic valued fat that could function as cocoa butter substitute (CBS), obtained through extraction of illipe nut Illipe nut's fat that results from extraction process can not be directly used, but should be previously refined. In this study, refining of illipe nut's fat was conducted through degumming and neutralization process. Degumming process was carried out by adding acids (acetic, citric and phosphoric) each with 20% strength at 0,4% (w/w) to the fat that has been previously heated. The results showed that degumming using phosphoric acid produced a better quality fat compared to that with citric acid and acetic acid. NaOH was used for neutralization process. The resulting neutralized fat was then examined for its physical-chemical properties which revealed that such properties were not so far different from those of commercial illipe nut's fat. The GC analysis as conducted on the refined illipe nut's fat showed that it consisted of various saturated fatty acid as well as unsaturated and other chemical compounds. All of the examined illipe nut's fat in this research showed that oleic acid is the dominant component.

Abstract

Delignification signifies as the crucial stages in converting lignocelluloses into ethanol. It affects further hydrolysis and fermentation processes. This paper looks into the effects of three different delignification processes (physical-, chemical-, and biological- treatments) of lignocellulosic biomass (i.e sawdusts of sengon and oil-palm petioles) on cellulose hydrolysis and fermentation. Physically, biomass was pressurized in an autoclave which has been set for 121°C, 1 atm for 30 minutes. Chemically, 1% H₂SO₄ was added during pressurized process. Biologically, pressurized biomass was inoculated using microorganism MD-14 FB.1 obtained from INTROF-CC collection For the control, biomass stuffs without chemical, physical, and biological treatments, sustained the hydrolysis/fermentation process as well. Delignification properties with regard to α-cellulose, lignin, hemicellulose contents in the treated as well as control biomass were examined according to the ASTM procedures. The amount of glucose exhibited from cellulose hydrolysis was determined by 3,5-dinitrosalicylic acid method, while the ethanol content was determined by potassium dichromate method. Results show that in general, chemical delignification is more effective than physical and biological treatments. It shows greater yield of lignin decomposition and sugar liberation in hydrolysis. Chemical delignification treatment produced about 0.0022 - 0.4046% ethanol from the substrate fermentation. The enzyme produced from the isolations has not significantly optimized the ethanol fermentation. Further research is needed in finding the compatibility between lignocellulose biomass and enzymes which were developed from microbe isolates.

Abstract

This research aims to examine the quality of manglid (Manglieta glauca Bl.) sawn boards through two sawing patterns, based on the defective shape and fiber separation. Samples of manglid logs were taken from community forest in Sodongbilir village, Tasikmalaya Regency, West Java. A total of 35 sawn boards from each of live sawing pattern and semi-quarter sawing pattern were taken as specimens. The research results show that type of shape defects occurred were twisting defect (55,91%), curving defect (53,57%) and arcing defect (41,35%). In terms of the fiber separation defects, all of defect types occurred including closed rupture (18,25%), opened rupture (14,13%) and splitted (2,82%). The arcing and twisting defects are significantly different between the two sawing patterns. The curving defect, closed rupture, opened rupture, and splitting are relatively similar between the two sawing patterns. Sawn boards from live sawing pattern bave a lower arcing defect and percentage of fresh sapwood, but have a bigber curving defect than those from semi quarter sawing pattern. Based on those defective shape and fiber separation defects, sawn board exctracted from live sawing patterns show's better quality than those of semi quarter refering to the Indonesian National Standard.

Abstract

Asteromyrtus brassi, is one of the cajuput oil tree species in Wasur National Park, Merauke, Papua. However, the information on the chemical compound and physical properties (qualities) of cajuput oil produced from this species is still limited. This research aimed to measure the chemical compound and physical properties of cajuput oil distilled from the leaves of A.brassi trees which grow at the Wasur National Park. Chemical compound analysis is using Gas Chromatography and Mass Spectrometer method (GC-MS method). The analysis on the physical properties was applied to the cajuput oil distilled using steam method. The distillation lasted for 4-5 hours, and every interval of 30 minutes the distilled cajuput oil collected cumulatively and the total collected oil was examined for the yield and physco-chemical properties. The qualities of the overall cajuput oil from A. brassi- tree leaves couldn’t satisfy the standard (SNI 06-3954-2006) because of the specific gravity is below 0.9 and optical rotation of 9.8. Analysis result with GC-MS show there are 29 peak, with 5 of them has the higher intensity identified as 1,8 cineole (34,88% concentration), Trans-Beta-Ionon-5,6-Epoxide (21,26%), Formamide (CAS) Methanamide (11,20%), Acetic acid (CAS) Ethylic acid (8,14%) and Alpha pinene (4,39%).

Abstract

This study examined characteristics of insulation board manufactured from the mixture of wood astes from Eucalyptus bybrid plantation forest (PF) logging and activated charcoal, and the adhesive as used was chitosan derived from the shrimp exoskeleton. PF-logging's wood wastes were reduced in size to chips, then made into pulp using open bot soda chemical process at the condition being alkali (NaOH) concentration at 8%, wood to liquor ratio 1:8 (w/v), and maximum cooking temperature 100C held for 3 hours. Insulation-board mat was formed using the wet process from the miscture of PF logging's wood wastes and activated charcoal at the proportions (w/w) consecutively 100% +0%, 97,5% + 2,5%, 95% + 5%, 92,5% +7,5%, dan 90%+10%. Prior to mat forming, to the miscture were added 2 kinds of adhesives separately (i.e. chitosan and tapioca as the comparison) 5% each. Physical and mechanical properties of the resulting insulation board with tapioca were better than those with chitosan. The greater the portion of activated charcoal mixed to the PF-logging's wood wastes, the lower the density and the strength (MOR), the more increased the moisture content, but the more improved the dimensional stability. The insulation board which revealed the most promising prospects and could favorably meet the JIS specification was the one from the mixture proportion of PF-logging's wood wastes and activated charcoal at 97.5%+ 2.5%, uring tapioca adhesive, and the one from solely 100% PF-logging wastes (without activated charcoal) using chitosan.

Abstract

The excperiment has been done to look into the utilization of Jatropa curcas oil for biodiesel as the alternative of the fossil-based diesel oil through the estrans (esterification and transesterification) process and the use of antiocidants. The estrans process brought about favorable changes in the oil characteristicus (eg, the decreases in density, viscosity, acid number, and iod number), thereby enhancing its performance as biodiesel. Three kinds of antioxidants were used (i.e. TBHQ, BHT, and Formula X), each with varying concentrations (0.03- 0.10%), and storage duration were imposed from the first until fourth week. The examined responses comprised of peroxide number, acid number, and kinematic viscosity. Reaching the fourth week, however, the wcidation process still occurred to the biodiesel oil despite using antioxidants (slight increases in peroxide number, acid number, and kinematic viscosity), but with the intensity far less than that of the control biodiesel (without antioxidant). The antioksidant regarded as the most effective inhibiting, such oxidation was TBHQ, followed in decreasing order by BHT and Formula X. However, the Formula X could expectedly perform as effectively as TBHQ and BHT, but with higher concentration (0.10%). The characteristics of biodiesel either the control or with antisocidants (up to the fourth week duration) could still satisfy the SNI criteria and those of fossil-based diesel oil.
