Abstract

Porang (Amorphophallus muelleri Blume) as a non-timber forest product (NTFP) has many advantagescompared to other food crops. In order to the cultivation aspect and excellence of the flour, it made this commodity afood sources in the future. Today, technical post-harvest processing become the current problems especially in gettingoptimum glucomannan. With increasing levels of glucomannan, it made the utilization and marketing of flour will bewider. This study aims to optimize of purification techniques of glucomannan. The research method is through soakingtechniques with ethanol (30%, 40% and 50%) and sodium bisulfite (2%, 3% and 4%). The results showed that theleaching technique ethanol made a significant effect on the increase in glucomannan levels. The immersion technique with50% ethanol and 2% sodium bisulfite can increase glucomannan from 32.65% to 83.96%. The process of soakingwith ethanol not affects the content of ferrum (Fe) and calcium (Ca) in porang flour.

Abstract

Pine resin is obtained from a process of tapping the pine tree (Pinus merkusii Jungh. & de Vriese). After processing, pineresin will produce gondorukem and turpentine. Currently, the utilization of turpentine is mainly for cosmetic, paint, a mixture ofsolvents, antiseptics, and pharmaceuticals. Due to an increase in the added value of the turpentine product, turpentine wassynthesized into borneol. This study aimed to analyze the characteristics of borneol produced from the synthesis of α-pinene usingNaOH and KOH bases. The method was carried out by synthesized α-pinene into borneol through sodium reduction using twoalkali e.i KOH and NaOH. The compounds were characterized by FTIR, NMR and GCMS. The results showed that onFTIR analysis of 12 samples of the borneol synthesized showed fairly similar absorption peaks with peaks appearing on standardborneol FTIRs. The NMR analysis of both HNMR and CNMR, compared with the standard NMR compounds α-pinene,champor and borneol, show that the peaks still show differences. The GCMS result showed the formation of the compound ofborneol compound with the percentage of 0.12 to 2.2% relatives. The type of base and origin of the turpentine used did not showany difference in borneol yield.

Abstract

Biomass resource mainly from forest industries waste such as oil palm empty fruit bunches (TKKS) is abundantly available, Currently, the utilization of TKKS as pyrolysis products is still limited to charcoal product, activated charcoal and charcoal briquettes. On the other hand, research on bio-oil manufacturing from biomass using fast pyrolysis method may increase hydrocarbons and calorific values, however the amount of catalyst used is higher than the biomass. This paper observes data and information on the characteristics of bio-oil made from oil palm empty fruit bunches through the addition of Ni/NZA as a catalyst. The optimal results (yield 30.27%, pH 2.94, specific gravity 1.068, viscosity 44 cSt and calorific value 29.38 MJ/kg with flame in medium category) were obtained with the addition of 6% catalyst. The bio-oil produced was dominated by acetic acid, phenol and benzene or toluene, and there were also alkene hydrocarbons compound, for instance hexadecene and aromatic hydrocarbons naphthalene.

Abstract

There are about 4,000 timber producing trees grow naturally in Indonesia, which comprise of commercially and lesser known wood species. Wood chemical component analysis is one indicator for timber utilization. This paper studies the chemical components of five lesser-known wood species originated from West Java namely ki bugang (Arthophyllum diversifolium Bl.), sempur lilin (Dillenia obovata Hoogl.), cangcaratan (Lithocarpus sundaicus Bl.), ki pasang (Prunus javanica Miq ), and ki langir (Othophora spectabilis Bl). The analysis was conducted according to the testing standard of Norman Jenkin, Indonesian National Standard (SNI) and TAPPI. Results show that Ki bugang has the highest content of both of cellulose and pentosan about 52.57% and 21,37%, respectively. Cangcaratan wood has the highest lignin content about 31.84 %. Ki langir has the highest solubility in cold water, alcohol benzene and NaOH about 3.34%, 2.75%, and 22.17%, respectively. In addition, sempur lilin has the highest solubility in hot water about 8.56%. The highest ash content is 3.60% belongs to Ki langir and the highest silica content is 1.92% belongs to sempur lilin. Based on the chemical content, cangcaratan wood is recomended for pulp and energy purposes and ki bugang wood is recommended for bio-ethanol.

Abstract

Hydrocracking of cashew-nut shell liquid (CNSL) into energy-affording fractions has been investigated using catalyst of acid-actiated natural zeolite (ZAA), to which were further impregnated unimetal (NiO) and bimetal (NiOMo) elements, thereby comprising two catalyst types (NiO/ZAA and NiOMoO/ZAA). This research aimed to examine how potential was the conversion of CNSL into energy-affording fractions, and to look into such metal impregnation into ZAA catalyst on the performance of hydrocracking reaction. Catalyst characterization included determining consecutively acidity using ammonia-base adsorption, and crystallinity using X-ray diffraction (XRD). Acid activation and metal impregnation increased the catalyst acidity and its crystallinity. The hydrocracking was carried out in a fixed-bed reactor employing the temperature 450°C, the CNSL feed/catalyst ratio of 6, and flow rate of H₂ at 20 ml/minute. The hydrocracking converted the CNSL into products that comprised the liquid-phase, gas-phase, and solid-phase (cokes) fractions, which in all afforded energy, and the conversion of each was examined. The liquid-phase product was further analyzed using gas chromatography (GC), which revealed that the GC's eluted liquid fraction were predominantly gasoline, diesel oil, and heavy oil. Each eluted fraction was further examined for its selectivity based on the elucidated GC area for each fraction over the total GC area for the overall liquid fractions. The hydrocracking performed optimally using NiOMo/ZAA catalysts. Which converted as much 75.42% (the greatest) of the CNSL as the liquid product, with also the greatest in selectivity towards gasoline and diesel-oil fraction at 38.45% and 19.87%, respectively. The impregnation of metal element, particularly bimetal (NiOMo) into ZAA catalyst indicatively enhanced the hydrocracking performance.
