Main Components

The chemical constituents of essential oils obtained from resin and bark of Agathis borneensis were analysed using capillary gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometer (GC/MS). The resin essential oil dominated by α-pinene (30.93%), δ-limonene (17.79%), β-pinene (11.28%) and terpinen-4-ol (8.35%). The main components in the bark essential oil were β-pinene (8.68%), terpinen-4-ol (8.54%), α-pinene (8.50%) and α-terpineol (8.48%).

The carbon isotope can be used to evaluate volcanism phenomenon of volcano. The study of carbon isotope of CO2 and CH4 was carried out in western Dieng Plateau by mass-spectrometer. Before analysis, sampel was separated by gas chromatography using a Porapak-Q column and a FID (Flame Ionization Detector) detector. The gas was oxidized by copper oxide at 850oC before being ionized in mass-spectrometer for isotope analysis. The CO2 content in Candradimuka crater (-4.10 O/OO), indicated that the gas may be as volcanic gas. The other CO2 from Sumber and western Gua Jimat, had isotope value  of -10.05 and -12.07 O/OO, respectively, indicating contamination from crustal and subduction material. The carbon isotope of CH4 gas from Pancasan village was -63.42 O/OO, that may be categorized as biogenic gas.   Keywords: isotope, CO2, CH4, Dieng.
