Abstract

Flavonoid compounds obtained from natural products could reduce the risk of cancer. Akway plants (Drimys beccariana, Gibbs) are endemic plants in the Papuan highlands, especially in Manokwari. D. beccariana has been widely used in traditional medicine in West Papua. This study aims to determine the cytotoxic activity of flavonoid from D. beccariana bark against T47D breast cancer cells. Pure compound form isolation was characterized using UV and IR spectrophotometers, and tested cytotoxic activity against T47D breast cancer cell using the Sulforodamine B. method. The D. beccariana stem bark (2.5 kg) was extracted with methanol solvent which was then partitioned with n-hexane and ethyl acetate solvents. Ethyl acetate fraction was separated and purified by column chromatography method to yield pure compound (7.1 mg). The UV-Vis spectrum of pure compound showed two bands at λmax 287 (I) and 205 nm (II), as well as the addition of AlCl3 shifting reagents with the addition of 7 and 5nm wavelengths, specific to the -OH and C=O groups in flavonoid compound. The infrared spectrum of pure compound (KBr) showed the presence of –OH stretch (3422 cm-1), C=O (1659 cm-1), C= C aryl (1463 cm-1), and C-O (1060 cm-1) which is typical for flavonoid. The pure flavonoid compound obtained from the of D. beccariana bark showed cytotoxic activity against T47D breast cancer cells with IC50 values of 3.2 µg/mL. D. beccariana is a promising source of breast anticancer agents.

Abstract

Lignocellulose biomass is a raw material for developing various promising products, such as wood waste, which can be used as raw material for the production of activated carbon as a catalyst. This research aims to characterize activated carbon for hydrolisis catalyst. In this study, the process of making activated carbon from mixed camphor and meranti wood was made through pyrolysis process at temperature of 500°C, followed by sulfonation using H2SO410N on reflux. The sulfonated activated carbon product (KA-SO3H) was then characterized according to Indonesia National Standard (SNI) including recovery value, moisture content, ash content, fly ash, fixed carbon, iodine absorption, while acidity and functional groups were measured using amonia adsorption and FTIR analysis, respectively. Furthermore, the sulfonated activated carbon was tested for its application in the hydrolysis reaction of rice husks using microwave with vary rice husk weight namely 2, 4 ,6 ,8, and 10 g at 400 and 600 W for 5, 7, and 9 minutes, respectively. The filtrate was then analyzed for its glucose levels using the DNS method (Dinitrosalycilic acid). The optimum condition of the hydrolysis reaction using sulfonated activated carbon catalyst were 400 W power, 1:8 ratio of rice husk and catalyst in 9 minutes duration. The optimum condition produced 330.51 ppm glucose levels with glucose yield percentages was 61.97%, and required energy was 216 kJ.

Abstract

Properties and quality of fibreboard products are much influenced by quality of the fiber materials, pressing process, and the amount and type of the used adhesive. The use of malic acid adhesives in the manufacture of medium density fibreboards (MDF) from mahang wood has low mechanical properties, especially modulus of static value. This paper studies on the effect of adding long fibers of pine wood and petung bamboo to improve the properties of MDF mahang wood with malic acid adhesives. The compositions ratio of mahang wood, pine wood, and petung bamboo fiber are 100/0/0, 90/10/0, 80/20/0, 90/0/10, 80/0/20, and 80/10/0, malic acid content of 25 wt % based on dry weight fibers and hot pressing at 180ºC for 10 minutes. Physical and mechanical tests were accomplished according to JIS 5905-2003 testing standard. Result shows the addition of long fibers of pine wood and petung bamboo increased the mechanical value of MDF from mahang wood. The best mixture of fiber is 90% mahang wood fiber and 10% petung bamboo, with value internal bonding 0.7 MPa, modulus of rupture 9.11 Mpa, and modulus of elasticity 2.5 GPa.

Abstract

Krasikarpa wood (Acacia crassicarpa A. Cunn.) is one of the fast growing peatland species for pulp and paper production. Pulp and chemical properties of krasikarpa wood under 4 years old have not been studied intensively. This paper examines pulp and chemical properties of krasikarpa wood during 1–4 years growth. Wood samples were taken from peatland area of Industrial Plantation Forest, PT. Arara Abadi, Riau. Chemical content examined includes extractives content in the solubility of ethanol benzene, lignin, and cellulose contents, while pulp properties studied were basic density, pulp productivity, and wood consumption. Wood samples were cooked using kraft pulping method with 18% alkali active, 25% sulfidity, wood to liquor ratio of 1:4, and temperature of cooking at 165°C for 3 hours. Experiment was designed based on Completely Randomized Design. Results showed that the age factor had a significant effect on all aspects studied. Based on further testing of LSD (Least Significant Differences), the significant effects included: extractive content at 4 years old, cellulose and lignin at 1 years old, pulp yield at 1 year old, density at 4 years old, wood productivity, and wood consumption at age 1, 3, and 4 years. After two years, extractive content start to increase, the lignin and cellulose content start to stabilize, and the pulp yield start to decline. Wood consumption decreases with age, the older the tree age, the lower the wood consumption.

Abstract

The presence of heavy metal chromium wasted from electroplating industry could harm human health, such as posing cancer and kidney failure. In order to overcome this problem, the effluent treatment was carried out by means of adsorption of chromium using wood activated charcoal. This paper aims to study the benefits of Muntingia calabura wood activated charcoal, especially seeking its optimal conditions for adsorption test and the ability of Escherichia coli bacteria to turn out chromium (VI) biodegradation into chromium (III) on chromium waste of electroplating industry. Wooden charcoal was produced after heating wood at 500°C for an hour and it was activated using hot water vapor at 800°C for 70 minutes and pressure 120 mBar. The adsorption test was conducted in variation of 20−100 mg/L of adsorbate initial concentration, contact time 45−105 minutes, and stirring speed of 100−300 rpm. Biodegradation test was conducted using Escherichia coli bacteria which was incubated in nutrient broth containing of adsorption waste. Results showed that the optimal conditions of the adsorption test was recorded at the initial concentration of 70 mg/L, 150 rpm stirring speed, 75 minutes contact time, and 86.7% adsorption effectivity. The biodegradation effectivity for turning chromium (VI) into chromium (III) was recorded at 98.6%.

Abstract

Wastes generated from processing of jabon wood (Antochephalus cadamba Miq.) and andong bamboo (Gigantochloa pseudoarundinacea (Steudel) Widjaja) were used as raw material for particleboard manufacture. The aim of this research was to investigate the effect of particle weight ratio of jabon wood and andong bamboo on physical and mechanical properties of particleboard. Laboratory scale particleboards with the dimension of 35cm x 35cm x 1.2 cm were fabricated using liquid phenol formaldehyde adhesive with six different compositions of particle weight ratio of jabon wood and andong bamboo (100:0, 70:30, 60:40, 50:50, 40:60, and 30:70). Results showed that the physical and mechanical properties of these particleboards were significantly affected by particle weight ratio compositions. Thickness swelling of jabon wood particleboard decreased by 11.19−40% resulted from the addition of andong bamboo particles in particleboard manufacture. The addition of 40% andong bamboo particles improved the MOR value of jabon wood particleboard by 11.49%. All particleboards studied meet the Indonesian and Japanese Standard requirements of particleboard except MOE value.
