GI, TPI, single sclerotinia, multiple sclerotinia


Sclerotinia as maceral from Group Inertinite is a mycelia mushroom, containing black melanin in the form of black cells. The fungus is rich in melanin to form sclerotinia cells. Sclerotinia is oval or circular consisting of single cells (single sclerotinia) and multiple cells (multiple sclerotinia), which has high reflectivity (Stach et al., 1982). The purpose of this study was to determine the condition of the peat swamp facies or changes in the swamp water level in Seam-B coal in the Marapi area, Lahat, South Sumatra. Changes in the water level of peat swamps in tropical climates affect the growth system of sclerotinia fungi on the peat surface. This condition can be seen from the Gelification Index (GI) values between 0.01 - 0.15 and various Tissue Preservation Index (TPI) between 8.68 - 36.50 (Diessel, 1986). The Seam-B coal facies in the Marapi area of South Sumatra consist of: limnic, limo-telematic, and marsh, these terms are used to determine the depositional environment based on the classification of the hydrological regime according to water level depth (Mitsch and Gosselink, 1986). Based on the results of the coal facies study (Diessel, 1986), there are variations of Seam-B coal facies which are deposited in limnic (wet / very humid) conditions where the sclerotinia fungus develops colony to form multiple sclerotinia in sample B (2), while sample B ( 1), B (3) and B (4) are deposited in conditions of marsh facies (moist soil) to limbo-telematic (relatively dry) so that some of the sclerotinia fungi develop separately to form a single sclerotinia (in relatively dry conditions) and some live independently colonize.
