Abstract

The science advancement in this century is such that in the future it will enter the nano technology. More specifically in the forest products field, the nano technology that can be developed is among others nano carbon derived from lignocelulosic stuffs. In relevant, this research aims to provide information and technology on the charcoal processing from lignocellulosic stuffs into nano carbon. The lignocellulosic stuffs used in this research consisted of teak wood and bamboo, further carbonized into charcoal at 400-500°C using drum kiln. The resulting charcoal was examined of its physical and chemical properties, crystalinity degree and dielectric characteristics, and then purified by re-carbonizing it at 800°C for 60 minutes. Prior to the purification, the charcoal sustained the doping (intercalation) process with Zn, Ni and Cu metals each respectively. After the purification, the charcoal was ground to very tiny particels using HEM (high energy machine) device for 48 bours. In this way, the charcoal with high crystalinity was yielded, and further sintered using spark plasma at 1,300 C into the nano carbon. The qualities and structure of all the resulting carbon (carbonized charcoal, re-carbonized charcoal, intercalated charcoal and sintered nano carbon) were evaluated using nano scale device (Py-GCMS, SEM-EDX and XRD), and examined as well of their dielectric characteristics. In turns out that the best quality charcoal was obtained from teak wood charcoal carbonized at 800°C, intercalated with Ni atoms at the ratio 1:5. The resulting charcoal afforded high crystalinity (78.98%), low electric resistance (0.17 2), and high conductivity 175.52 2'm Qualities of the corresponding nano carbon (after sintering) were such that its crystalinity spectaculary reached 81.87%, resistance (R) 0.01 & with very bigh conductivity 1067.262'm'. The nano carbon that resulted seems favorably prospective for bio-censor, bio-battery, and bio-electrode. Accordingly futher related research deserves carrying out.

Abstract

Commercial biodiesel of oil palm is controversial as the palm oil is classified as food oil and palm plantation utilizesfertile land. One potential type of vegetable oil as biodiesel raw material is kemiri sunan (Reutealis trisperma(Blanco) Airy Shaw) oil. This research aimed to prepare a heterogeneous solid catalyst in the form of an impregnatedSiO2by CaO catalyst (CaO/SiO2), to study the effect of the esterification stage on free fatty acid (FFA) content ofoil, and to test the activity of the CaO/SiO2catalyst during the trans-esterification stage for biodiesel formation. CaO/SiO2catalysts were prepared by sol-gel method made from natural materials (egg shells and rice husk). The FFAcontent of kemiri sunan oil was determined through various esterification stages namely 1; 1.5; and 2 hours in thepresence of H2SO4catalyst. While the trans-esterification stage was carried out under reaction temperature of 60°C,oil to methanol ratio of 1:9, reaction time of 2 hours and CaO/SiO2catalyst content of 3%. The results showed thatthe esterification stage for 1; 1.5; and 2 hours reduced the FFA content from 12.5% (without esterification) to 0.65%;0.58%; and 0.54% respectivaly. Biodiesel made from kemiri sunan oil which was synthesized with the addition ofCaO/SiO2catalyst at optimal conditions of trans-esterification stage fulfilled SNI 7182-2015: Biodiesel based ondensity, viscocity, moisture content, iodine number, and cetane number.

Abstract

Illipe nut in Indonesia still serves as one of the essential export commodities from the group of non-wood forest products. These nuts unfortunately are traded only in form of the dried fruits. Attempts are necessary to enhance the added value of illipe nuts. Among them is through the processing of the fruit into fat. One manner to extract the fat portion from the illipe- nut fruits is using organic solvent. In relevant, research was conducted on the extraction of illipe-nut fat from its fruit of 4 specier Shorea spp which was originated from the experiment station in Bogor, West Java. Fat extraction was conducted using bexane as the sohvent. The resulting fat was then examined for it physical-chemical properties and sustained the GC- MS (Gas Chromathography-Mass Spectrometry) analysis. The result revealed that the illipe-nut fat from 4 tree species varied in fat yield and its physical-chemical properties (Le. moisture content, acid number, free fatic acid and ind number). The GC-MS analysis indicated that illipe-nut fat contained various saturated fatty acid as well as unsaturated and other chemical compounds, such as phenol, aldebryde, bydrocarbon (aliphatic and cyclic) and hexane (presumably from the organic solvent). Oleic acid is dominant chemical component of S. stenoptera and S. parvifolia, metbyl oleate in S. pinanga and methylene-(4-trimethylsilanyl-phenyl)-amine in S. mecisopteryx.

Abstract

Thirty wood species originated from various regions in Indonesia were tested against powder-post beetle. Representative wood samples with the dimension of 7.5 cm x 5 cm x 2.5 cm were taken from each tree species and tested against powder post beetle (Heterbostrychus aequalias Waterh) for six weeks. Observation was carried out on the tested specimens, and the observed parameters comprised of the weight loss percentage and the survival rate of powder-post beetles. Besides, subjective observation was also performed on regard to the degree of the attack. The obtained data (i.e. wood-weight loss, beetles' survival rate, and degree of attack were further classified into five categories based on the resistance characteristics. Based on wood-weight loss revealed that as nine of the 30 wood species were regarded as class I (29.99%), three species as class II (9.97%), eight species as class III (26.67%), six species as class IV (19.99%), and four species as class V (13.33%). Pertaining to beetles survival rate, five species were categorized as class I (16.67%), three species as class II (9.99%), 12 species as class III (39.99%), eight species class IV (28.67%), and two species as class V (6.67%). Further, with regard to the degree of beetle attack, five species belong to the criteria of severely attacked (16.67%), whereas consecutively 16 species were classified as moderately attacked (53.33%) and nine species as slightly attacked (30%).

Abstract

This paper presents to the resin content and the chemical composition in agarwood with several quality using gas chromatography mass spectrometry. The agarwood qualities as tested were those super and kemedangan classes originated from Bangka, Papua and Assosiation of Indosnesia's Agarwood Exportry Enterprise (Asgarin). Results revealed the resin yield of super quality agarwood was higher than that of kemedangan-quality counterpart. Agarwood with high resin content was regarded a high (super) quality, and its chemical composition was predominantly chromone and gamma gurjunene. On the contrary, agarwood with low quality (kemedangan) chemicallyy comprised 2.5 furandione, 3-dodecenyl and agarospirol. Further super-quality agarwood chemically contained more sesquiterpene than kemedangan-quality. Sesquiterpene and chromone compound were indicatively responsible the fragrant arome revealed by agarwood. The quality of agarwood in the same quality class but originated from different regions revealed the resin content as well as chemical composition which was different fromeach other.
