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.

Objective: The aim of this study is to map out the distribution and composition of the main active components found in stingless bee propolis from various regions in Indonesia. Methods: The stingless bee propolis used was obtained from ten different provinces in Indonesia and the active components analysis using Gas Chromatography-Mass Spectrometer (GC-MS) pyrolyzer. Results: This study found 85 main types of active components with concentrations of ≥ 1%. The most frequently found active component was alpha-d-glucopyranoside, which had an average concentration of 28.20%. Conclusion: There were differences between the main active components found in 14 samples of stingless bee propolis obtained from 10 provinces in Indonesia, which was due to the variety of bee species and plant origin.
