Abstract
The research was done to obtain the isolates of soil borne fungi isolated from mangrove rhizosphere which were capable of degrading petroleum hydrocarbon compounds. The soil samples were collected from South Sumatra mangrove forest which was contaminated by petroleum. The isolates obtained were selected based on their ability to survive, to grow and to degrade polycyclic aromatic hydrocarbons in medium containing petroleum residue. There were 3 isolates of soil borne hydrocarbonoclastic fungi which were able to degrade petroleum in vitro. The 3 isolates were identified as Aspergillus fumigates, A. parasiticus, and Chrysonilia sitophila. C. sitophila was the best isolate to decrease total petroleum hydrocarbon (TPH) from medium containing 5-20% petroleum residue. Keywords: Hydrocarbonoclastic fungi, hydrocarbon compounds, mangrove rhizosphere

Nature on Soil Phisical, Chemical and Ftir Spectrophotometry of Hydrophobic Peat From Central Kalimantan
This water-loving character is altered to water-repellent character in hydrophobic peat soils
Artificial hydrophobic peat soils were yielded by oven-drying the native hydrophobic peat soils at 50 oC
Summary
Pengambilan contoh gambut dikondisikan sesuai dengan keadaan aslinya yaitu mewakili gambut hidrofilik dan hidrofobik. Gambut hidrofobik diambil dari wilayah Berengbengkel, Palangkaraya, Kalimantan Tengah, merupakan lahan yang telah diolah secara intensif dengan kondisi hidrofobik (G1), sample gambut hidrofobik yang lain diambil dari desa Kalampangan dengan kondisi lahan bero bekas terbakar tahun 2005-2006 (G2). Untuk mewakili gambut hidrofilik diambil dari desa Kelampangan, di lokasi bekas Blok C Proyek Lahan Gambut Sejuta Hektar (G3). Kondisi gambut Kelampangan hidrofobik (G2) merupakan campuran hidrofobik dan hidrofilik sehingga untuk memperoleh gambut yang semuanya hidrofobik maka gambut Berengbengkel (G4) dan Kelampangan (G5) dikering oven pada suhu 50 oC selama 10 jam (Masganti, 2003). Dengan demikian ada lima kondisi gambut yaitu G1 (Berengbengkel hidrofobik alamiah), G2 (Kelampangan hidrofobik alamiah), G3 (Kelampangan hidrofilik), G4 (Berengbengkel hidrofobik buatan), dan G5 (Kelampangan hidrofobik buatan). Selanjutnya gambut yang dibuat pelet dianalisis gugus-gugus penyusunnya dengan FTIR Spektrofotometer dan interpretasi menurut Flaig et al (1975)
