Ramania fruit ( Bouea macrophylla Griffith) is a tropical plants, as a new natural source of polyphenols. The content of these polyphenols is very abundant, especially in the seeds. The polyphenol content is widely used in the pharmaceutical world, as antibacterial ingredient. The development of natural antibacterial compounds from plants is needed to be used as a therapeutic treatment for bacterial infectious diseases. The purpose of this study is to determine the potential of ramania seed extract, seed coat and pulp against several types of pathogenic bacteria ( Escherichia coli, Enterococcus aerogenes, Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella thypimurium, and Propionibacterium acnes ) that generally cause disease in humans. Ramania fruit is divided into three parts, such asseeds, seed coatand pulp. Antibacterial testing was done by agar diffusion method. The concentration of the extract for antibacterial tests were 1000 ppm, 500 ppm and 250 ppm.The MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) values were calculated using the microdilution method using 96-well micro-titre plates. The results showed that ramania seed extract had the highest antibacterial activity compared to seed coat extract and pulp. Inhibitory zone of Ramania seed extract ranged from 23-30 mm at a concentration of 1000 ppm and still had inhibition effect up to concentration of 250 ppm. MIC value of seed extract with methanol solvent was 78.13 μg/mL against three types of bacteria ( P. aeruginosa, P. acnes, and S. thypimurium ).

Galam l iquid smoke is a liquid product derived from c arbonization process of Galam wood (Malaleuca leucadendra) which can be used as natural preservative to fish. The incorporated edible film packaging with l iquid galam wood is a good alternative to inhibit the deterioration of fish qua lity during storage. This study aims to determine the effect of liquid smoke of galam wood in corporated into edibl e film to the deterioration of catfish (Pangasius sp) quality. The treatment factors used were (i) the edible film - gelatin e formulation (G), g elatin e - pectin (G - P), liquid smoke - gel atine (G - AC) and gelatine - pectin - liquid smoke (G - P - AC). It was compared with control (without treatment). The other factors were (ii) storage duration of 0 hour, 2 hours, 4 hours and 6 hours. The observed degradation p arameters were Total Volatile Base - Nitrogen (TVBN) and microbiological testing. After being stored for 6 hours , t he highest value of TVBN was found in the control without treatment ( 54 mgN/100g ), while the lowest TVBN value was g elatine - pectine - liquid smok e (1 8 mgN/100g ) . T he microbiological test showed that the highest TP value was found in the control which reached 1 . 6x10^9 , while the gelatine, gelatine - pectin, gelatine-l iquid smoke and gelatine - pectin - liquid smoke were log 5 . 7x10^8 ; 1 . 0x10^8 ; 3 . 5x10^8 ; and 7 . 0x10^8 respectively. The gelatin e - pectin - liquid smoke (G - P - AC) treatment is able to inhibit the decrease of catfish quality on TVBN value at 6 hours of storage, while TPC value is more stable on gelatine - smoke treatment (G - AC) at 2 to 6 hours. The results of this study indicate that the addition of liquid smoke is able to inhibit the declining quality of catfish.

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.

Acacia mangium knot is 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 400 o C 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 10 o C/ min showed the pyrolysis reaction at temperature of 200 o C-750 o C 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.

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.
