Antibacterial activity test Staphylococcus aureus and Salmonella typhihas been performed by microencapsulation product of rogo essential oil (Premnaserratifolia Linn). This study aims to determine rogo oil activity test and microencapsulation results as antibacterial S. aureus and S. typhi. The results of antibacterial activity of rogo liquid oil to S. aureus and S. Typhi bacteria showed different inhibitory power of each concentration variation of 12.5%, 25%, 50% and 100% with 100% concentration as the best inhibitor for both bacteria. While the antibacterial activity test of S. aureus and S. typhi from microencapsulated rogo oil: maltodextrin showed the difference of each variation of concentration 1:10; 1:12; 1:14; 1:16 and 1:18 with a 1:14 composition of S. aureus and 1:18 in S. typhi as the best ratio of activity power. The antibacterial activity test between liquid rogo oil and microencapsulated result shows the difference, but it can be concluded that the inhibitory power of rogo oil from microencapsulation is more inhibited than 100% rogo oil.

This research examines the characteristics of microwave assisted pyrolysis products of cashew nutshell waste (CNS). The pyrolysis process of CNS conducted with microwave heating of 400 W for 60 minutes. Pyrolysis product such as bio-gas, bio-oil and bio-char were identified using proximate and ultimate analysis, scanning electron microscope (SEM), thermogravimetric analysis (TGA/DTG), gas chromatograph-mass spectrometer (GC-MS) and Fourier Transform InfraRed (FTIR) Method. There is a significant increasing in volatile matter and fixed carbon of derived bio-char and the porous structure was observed in a range of macropore after pyrolysis. The TGA profile reveals CNS sample lost about 71.25% of mass before reached 750℃. The highest decomposition rate on the DTG profile was 0.57 mg/min and 0.56 mg/min as observed at about 261.2℃ and 340.3℃. Bio-oil yield has density of 1.036 gr/ml, viscosity of 19.5 cst after water removing, flash point of 138℃ and HHV of 21.7 MJ/kg. The GC-MS of the bio-oil shows about 53% phenol, 19% palmitic and oleic acid, 11% cyclobutene, 14% ethyl and methyl ester, and cyclopentene and cyclohexane in small amounts in accordance with FT-IR results.

Grapsus albolineatus is one of marine crustaceans which have carotenoid (astaxanthin) pigment. This research was conducted to analyze carotenoids (astaxanthin) extracted from G. albolineatus, and evaluate their in vitro antibacterial activity. The research was done in March-July 2002. Samples were collected from Manado Gulf, North Sulawesi. The result indicated that the carapace contained 4 carotenoids namely ß-caroten, ecinenon, astaxanthin diester, and astaxanthin monoester. In addition, the epidermis contained free astaxanthin. In vitro antibacterial activity test indicated that astaxanthin had low bacteriostatic activity against Psedomonas aeruginosa, Enterobacter cloacae, Staphylococcus aureus, and Proteus stuartii.

Skin infections most often found in developing countries, especially in the tropics, are purulent skin inflammation (pyoderma), the main cause of Staphylococcus aureus. The increasing number of cases of bacteria that are resistant to antibacterial can encourage the extraction of sources of antibacterial drugs from natural ingredients. One of the plants that is thought to have the antibacterial activity of Staphylococcus aureus is the Neem plant. In this study an antibacterial activity test was carried out with the well diffusion method from 96% ethanol extract of Mimba leaves extracted by percolation method. Previously 96% ethanol extract from Mimba leaves had been identified by secondary metabolites by phytochemical screening and standardized extract testing. Standarization using non-specific parameters (moisture content, ash content and drying losses) found that 96% ethanol extract of Mimba leaves entered a range of standard parameters and in phytochemical screening tests obtained 96% ethanol extract of Mimba leaves containing alcaloid, saponins, tannins, steroids / terpenoids and flavonoids. The results of the study on the antibacterial activity test showed a concentration of 75% ethanol extract of 96% Mimba leaves classified as having strong activity, at a concentration of 50% and 25% classified as having moderate activity. Based on this study it can be concluded that the three concentrations of 96% ethanol extract of Mimba leaves were able to inhibit the growth of Staphylococcus aureus bacteria.
