Abstract

Charcoal was the residue of the decomposition of wood from heating process whereas the chemical component was carbon. One of the charcoal production methods used was a kiln drum with carbonisation mixed system. This research aimed to identify and analyse the quality of teak wood charcoal made by carbonisation mixed system with the addition of sawdust teak using kiln drum method. Teak wood pieced in 5-10 cm diameter were charred by the addition of sawdust (70:30) to maintain the temperature process ranged between 4000C and 4500C. The parameters that were observed were yield, water content, volatile substance content, ash content, bonded carbon content, the percentage of charcoal that retained at 6.35 cm sieve and that passed the 3.18 cm sieve, calorific value, density and color. The results were then analyzed descriptively and been compared to the SNI 01-1683-1989. The yield of teak charcoal in this experiment was 21.3%, while water, volatile substance and ash content were 3.93%, 16.57%, and 3.25%, respectively. The percentage of charcoal retained at 6.35 cm sieve was 88,68%, and the ones passed 3.18 cm sieve was 1, 96%. The charcoal’s bonded carbon content was 80.18%, it’s calorific value was 7141 cal / g; and the color was black.Keywords: carbon, sawdust, carbonization temperatures

Abstract

The development of a wound dressing is necessary to accelerate wound closure, promote tissue growth, and reduce scar formation. Hydrogel can be used as an ideal wound dressing. There are many materials that can be used as ingredients in the manufacture of hydrogels such as glucomannan and xanthan gum. The addition of antibacterial compound to wound dressing hydrogels such as sappan wood extract can be used to further improve the wound healing process, and avoid skin infections. In this study, hydrogel glucomannan-xanthan gum was prepared using a concentration of 1% xanthan gum: glucomannan (50:50 and 60:40), 2% xanthan gum: glucomannan (50:50 and 60:40) with the addition of 2% sappan wood extract. Furthermore, the water content, FTIR and antibacterial activity were determinate. The data showed that the hydrogel had excellent physicochemical and antibacterial properties. All the formulation of xanthan gum and glucomannan can formed hydrogels at 37° C and lower. The FTIR result showed the formation of new hydrogen bonds between glucomannan and xanthan gum. The hydrogel added with secang extract was able to inhibit E. coli and S. aureus with an inhibition zone of 7.0 -7.5 mm and 16.25-18.50 mm, respectively. Hydrogel was suitable for application as a wound dressing.

Abstract

Bangkal bark is one of the plant materials widely used by local people of South Borneo for medicine and beautycare. The limited research explores the extraction process and biological activity of bangkal bark for this use, especiallyfor acne treatment. This study was conducted to determine the difference of extraction methods and solvent polarity tophytochemical contents, antibacterial and radical scavenging activities of bangkal bark extracts. Bangkal bark wasextracted by maceration, percolation and soxhletation methods with various solvents, namely water, 96% ethanol, 70%ethanol and ethyl acetate. Total phenolic content by Folin ciocalteu, total flavonoids with AlCl3, and total tannins withvanillin were determined. Free radicals scavenging activity was determined with DPPH free radicals and antibacterialwith agar diffusion method. Soxhlet method with 96% ethanol solvent showed the highest phenolic content about81.12±1.66 mg/gr GAE. The highest flavonoid content was found on the percolation method with ethyl acetateabout 24.24± 0.057 mg/gr QE. Total tannin content was found on percolation methods with 96% ethanol about36.92±0.81 mg/gr CE. All of 70% ethanol extract showed high inhibitory strength of DPPH radical above 87%at a 1 mg/ml concentration. Antibacterial activity in the extract showed that all methods and solvents had inhibitoryproperties against P. acne with various inhibitory zones. In contrast, only ethyl acetate and water extracts were able toinhibit P. acne and S. aureus both.

Abstract

Bangkal bark is used as a cosmetic raw material by residents of South Kalimantan and has been proven to havegood pharmacological activity as an antibacterial and free radical scavenger. Phenolic is one of the compounds found inbangkal plants. It can be used as markers to standardize and determine the extract stability that will be developed aseffective and safe materials. This study aims to observe antibacterial and free radical scavenging active materials thatstable and safe from bangkal bark for application in pharmaceutical and cosmetic products. The extraction process useda percolation method with distilled water, then standardized according to the PPOMN reference and tested for stabilityusing the accelerated stability method with a total phenolic marker. The extract was tested for free radical scavengingactivity against DPPH, and antibacterial activity was tested against Propionibacterium acne and Staphylococcusaureus by disc paper diffusion method. The results showed that bangkal extract was stable during testing at 40°C and75% RH for 12 weeks. Total phenolic range between 7.18 ± 0.31−7.43 ± 0.21 µg/mg. Antiradical scavengingactivity showed a value of IC50 of 3,158.3 μg/ml, and antibacterial activity testing showed MIC value of the angkalextract against P. acne and S. aureus at ≥ 100,000 ppm and 100,000 ppm. Extract standardization results showedthat the bangkal wood extract met the quality standard and could be used as a raw material for cosmetic materials.
