Abstract

Corn stalk is considered as agricultural by-products that is abundance and easy to obtain in Indonesia. Corn stalk is an agricultural by-product that highly potential to be exploited as raw material for particleboard production. The research was aimed to evaluate the use of corn stalk in the production of particleboard especially for its acoustics and physical properties. Targeted board density was 0.5 g/cm3and 0.7 g/cm3. The Adhesive used in the board production were urea formaldehyde 10%, phenol formaldehyde 10% and isocyanate (pMDI) 10% based on their solid content. Board dimension was 35 x 35 x 1 cm. The pressure used was 25 kgf/cm2, temperature of 130℃ and 150℃ for 10 minutes. After production, boards were conditioned at room temperature for 7 days prior to testing. The standard for physical and mechanical properties JIS A 5908-2003, Acoustic properties testing was according to JIS A 1405-1963. The result shows that particleboard with isocyanate adhesive both with low and medium density had the best result. Acoustic testing shows that the highest sound absorption coefficient was given by particleboard with isocyanate at frequency 1500 Hz.

Abstract

The quality of rubber cup lump is ditermined by several factors, one of them is the latex coagulant. The type of latex coagulant also affects the coagulating time. Liquid smoke is one of the most recommended latex coagulants due its save and effective operation. Deorub, the most popular liquid smoke, is made from shell of oil palm kernel. There are still many alternatives of liquid smoke materials that may have lower economic values. This study was aimed to evaluate and compare the performance of three liquid smokes produced from three alternative materials namely galam wood, rubber wood, and oil palm frond as latex coagulants. This study was performed using groups random design with two factors, namely type of coagulants and the concentrations (10% and 5%). Evalution was performed on the speed of coagulating time and also the quality of rubber cup lumps resulted by the tested coagulants, such as water content, rubber dry weight, ash content, and also the value of sensory quality (smell, color, texture, and the bubble). Liquid smoke resulted from oil palm fronds showed the best performance due to it’s lowest pH value (2.5) and the shorthest coagulating time (40 min) at concentration of 10%, which produced rubber lumps with rubber dry weight of 99.86% and ash content of 0.83%. Meanwhile, the highest yield of liquid smoke was resulted from galam wood (10%) with coagulating time of 72 minutes.

Abstract

The purpose of this study was to analyse the physical abilities and microbial contamination of modified sago starch using propylene oxide by the hydroxypropylation method. The research design used was a complete randomized design in which the fixed variable was modified propylene oxide sago starch. While the non-permanent variables used sodium tripolyphophate (STPP) at a concentration of 0.3%; 0.5%; 0.6% (b/b) and carrageenan at a concentration of 3%; 2% (b/b). This process was carried out in two stages, adding plasticizers (glycerol) and without plasticizers with a concentration of 2% (v/v). Aquadest used as a solvent with the total amount 100% (b/v). The results of testing he physical properties of the FTIR test process indicate the presence of a spectrum in the region of 3000 - 2500 cm-1 which was a specification of propylene oxide. Whereas for the solubility test of sago starch for water, acid and alike intestinal fluid it met the standards according to Farmakope Indonesia 4th ed. Testing of microbial contamination in pathogenic bacteria types, namely E. coli, Salmonella, and Staphylococcus aureus gave negative test results, whereas for the total plate value (ALT) of sago starch capsules shells showed a value of 1.5x102 cfu/g.

Abstract

Acacia mangium knotis one of the biomass reject produced from the wood chemical pulping processes. This raw material is suitable for the production of bio-oil and bio-char in competitive costs. Utilization of the knot for the production of bio-oil and bio-char makes pulp mill as a bio-refining system with many profitable products because of increased income from bio-oil and bio-char and reduced costs for solid waste disposal. This study aims to evaluate the pyrolysis of knots from the kraft pulp mill to produce bio-oil and bio-char. Pyrolysis experiments of Acacia mangium knotwere carried out using laboratory-scale fluidized bed reactors at 400oC for 30 minutes. Acacia mangium knot contains volatile matterof 69.90% (dried basis) with a calorific value of 4279 kcal/kg (dried basis) has potency to produce bio-oil through the pyrolysis process. The TG-DTG analysis with heating rate of 10oC/min showed the pyrolysis reaction at temperature of 200oC-750oC resulting in a mass decreasing from 90% to 30% or around 85% of total conversion. The yield of bio-oil from fast pyrolysis was about 47%. Bio-oil contains high various organic compounds and dominated by acetic acid (21%) and 2-propanone (28%), and produced bio-char with a calorific value of 5763 kcal/kg (dried basis). Bio-char products could be used as a solid fuel in the combustion process or gasification process.

Abstract

Ant nests (Myrmecodia sp.) are one of the medicinal plants that have many benefits for health. Ant nests are widely used as antimoicrobial, antidiabetic, anticancer and antiimplantation because ant nests usually contains chemical compounds such as flavonoids, terpenoids, saponins and polyphenol tannins. Flavonoids can be used as antioxidants, antiangiogenic, and antimicrobials. Many products can be developed from the extract, such as tea, powder and ant nest capsules. Another product innovation that needs to be developed is gum. It is important to conduct research to determine the optimum formulation of ant nest extract as an additional ingredient on candy products (gum). This study aims to determine the antimicrobial and antioxidant activities of ant nests extract and maximize the use of ant nest extractas at additional raw material for high quality gum. The ant nests were extracted using 70% ethanol. The concentrated extract was tested for antimicrobial activity in four types of pathogenic bacteriaEscherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538, Streptococcus mutans ATCC 25175, Pseudomonas aeruginosa ATCC 9027, and Salmonella typhimurium ATCC 14028); antimicrobial positive control was tested using chloromphenicol and antioxidant activity positive control was tested with ascorbic acid (vitamin C). Dried ant nest extract was added to the gum mixture as much as 0.15% and 3% and then the quality was tested based on the parameters according to the quality standard of gum. The results of this study showed that ant nest extract had effective antibacterial activity in gram-positive and gram negative bacteria with an inhibitory zone of 10-13.5 mm. The high antioxidant activity of ant nests (85.90%) proven that ant nests had the potential as an natural antioxidants added in food. The addition of 0.15% and 0.3% extracts in chewing gum generally produced gum that met the quality standards of chewing gum, although the moisture content was slightly higher than the maximum limit of the standards.
