Abstract

Studies of timber extraction was carried out in steep areas by using the prototype Expo-2000 Generation II withengine of 13 HP. Cable line stretching of about 400 m with slope of about 50%. Logs of rasamala of 2-4 m length anddiameter ranged of 20-40 cm were extracted to landing around a tower. The machine was placed on the hill located in themiddle of two cable stretches.The first cable stretch was used for pulling logs upward and the second cable stretch for pullingdownward. The cost for machine investment was about Rp 110 millions with operation costs of Rp 111.975 /hour. Logsextraction productivity is 0.59 m /hour, and the extraction cost was about Rp 189,788 per m .

Abstract

Biocharcoal is a specific charcoal that can store carbon in soil almost permanently, and be able to improve its humidity aswell as fertility. This paper observes the use of biocharcoal and wood vinegar to stimulate jabon and sengon seedlings.Biochar and wood vinegar were made of sawdust, charcoal, compost charcoal (a mixture of sawdust charcoal and compost)and wood vinegar (the condensed gas/vapor fractions that evolved during sawdust carbonization). Sawdust and compostcharcoals were mixed thoroughly and evenly with the top soil for jabon and sengons media. Wood vinegar in 2%concentration was then poured and sprayed onto the planted seedlings. Similar seedlings were also planted on the untreatedsoil media as a control. After five months seedlings growth characteristics (i.e. height and diameter) were observed andmeasured. Results show that in general, height and diameter of the seedlings planted in treated media are improved.Seedlings of Jabon are increased by 16.38 , 21.05 , and 62.74 times in height as well as 1.70 and 3.10 times in diameterthan those of control. Seedlings of Sengon are increased by 22.50, 21.10, 40.80 times in height as well as and 1.04 and1.03 in diameter than those of control.

Abstract

Dryobalanops aromatica is a woody plant that produces non timber forest product such oil and crystal. Thechemical composition information is important for oil utilization and specific marker of the material. Traditionally, oilquality was grouped based on its colour. The whiter the colour, the better the quality. This paper examines the chemicalcontent of four oil groups and two kinds of crystal. The examination was carried out in Gas Chromatography MassSpectrometry (GCMS). The results show that the oil of Dryobalanops aromatica 1 contains borneol up to 26.02%, D. aromatica 2 contains 13.95%, D. aromatica 3 contains 24.03%, and D. aromatica 4 contains 1.09% in longiborneol form. Meanwhile, crystal 1 contains 92.70% of borneol and crystal 2 contains 90.73%. Borneol compoundcan act as chemical marker of Dryobalanops aromatica.

Abstract

Smoke liquid is a condensation product of raw material combustion containing cellulose, hemicellulose and lignin. Itproduces many compounds that have antimicrobial, antibacterial, and antioxidant effect such as organic acids and itsderivatives. Bintaro fruit shell is a waste of oil processing bintaro that are not utilized. Generally, latex coagulation usesformic acid or acetic acid that it's expensive and less environmentally friendly. Bintaro shell pieces is unused material andcontaining cellulose, hemicellulose, and lignin made into smoke liquid that is acidic and could reduce pH so the latex willcoagulate faster. The purpose of this study was to use smoke liquid of shell bintaro fruit shell as an alternative coagulant forrubber latex material.Smoke liquid wasmade using a modified drum kiln with a temperature of 400 C for 7 hours. Smoke liquid is purifiedby distillation up to 200 C. Smoke liquid that has been purified, further analyzed of its physical properties such as watercontent, viscosity, specific gravity, pH, acidity and phenol. Application of smoke liquid as rubber coagulant where doneusing smoke liquid concentration of 5%, 10%, 15%, 20%, while smoke liquid from coconut shell was used as acomparison. The results showed that the best results for coagulating was obtained from bintaro shell concentration of 20%and the fastest time for coagulating obtained from coconut shell smoke liquid concentration of 5%. Bintaro shell smokeliquid can be used as a rubber coagulant but for coagulation time isnot as fast as coconut shell smoke liquid.

Abstract

Due to limitation of resources the availability offossil fuel is become decreasing, an alternative fuel is needed such as Aleurites trisperma Blancoseed before of big potential as source for plantation, the composition of seed kernel hasa highlevel of oil (43.3%).Biodiesel production process was done in the laboratory, its objective to establish the optimum condition. The addition ofcatalyst H PO (degumming process) of 0,5%, 0,75%, 1%. The esterification treatment use a methanol catalyst mixtureof 10%, 15%, 20% with HCl and H SO of 0,5%, 0,75% and 1%. The transestrification treatment use a methanolcatalyst mixture of 10%, 15% and 20% with KOH and NaOH of 0,2%, 0,4%, 0,6%. Optimum results will beapllied to biodiesel production in large scale.In making Aleurites trisperma Blanco biodiesel which meet the Indonesian National Standard quality (SNI),chemical used were mixture of methanol 20% (v/v) and catalys NaOH 0.6% (w/v), where resulting in biodiesel withmoisture content 0.05 %, acid number 0.76 mg KOH/g, free fatty acid content 0.38 %, density 865 kg/m , kineticviscocity at 40 C of 5.41 mm /s (cSt), base number 101.49 mg KOH/g, alcyl ester content 104.55% massa, iodnumber 109.73 g I /100 g, cetana number 59,08, and yield of biodiesel oil 79.92 %.

Abstract

Pine resin is one kind of non wood forest products (NWFP) that has passably potency and Indonesia occupies thirdrank in the world as a producer pine resin after China and Brazil. The good market opportunity of gondorukem pushedmanagement of forest to increase pine resin production. This paper aims to give information about harvesting of pine resinusing three tapping techniques. The tapping techniques depends on tapping tool is used, namely mujitech, drill and kedukul.The results showed that the highest production of resin was obtained from the technique using kedukul, 18.0g/quare/collection whereas from Mujitech dan drill was 11.5 g/quare/collection and 11.2 g/quare/collectionrespectively. From visual observation, resin obtained by drill technique was cleaner than Mujitech and kedukul techniques.The content of impurities in pine resin that produced by drill technique was 4% on average. Nevertheless, drill tappingtechnique is not preferred by farmers to apply as less effective.The application of tapping techniques at a certain location were influenced by the customs of the local communities.And those customs were not easy to be changed with new technique although that can produce the tapping more thanmanually technique.

Abstract

This research aimed to look into the hydocracking potential of CNSL into fuel fraction with the aid of catalyst. Thebased materials of catalyst as used were Y-zeolite from Japan and Nickel metal (E-Merck). NiO/ZY catalyst wasprepared with wet impregnation method using salt precursor Ni(NO ) .6H O into Y-zeolite as a supporting stuff.Catalyst characterization was determined by gravimetry method to examined acidity of catalyst with pyridine base as aadsorbate base and catalyst porosity using Surface Area Analyzer (NOVA-1000). Hydrocracking process was carriedout in a fixed-bed system reactor using NiO/ZY catalyst at temperature of 400°C with H flow rate of 20mL/min, andthe ratio of feed/catalyst equal to 4. The results product was analyzed using Gas Chromatography (GC). Results showedthat CNSL hydrocracking with NiO/ZY catalyst brought out liquid product as much as 80.03% in portion withselectivity on gasoline, diesel and heavy oil are 38,47%, 25,88% and 15, 74%, respectively.
