| dc.description.abstract | The presence of selulolitic fungi in the former eruption land of Mount Sinabung
eruption in Karo. Under guidance of DENI ELFIATI and DELVIAN.
Volcanic ash expelled in the wake of eruption has a sour potential of hydrogen
and the result led to a decrease in the diversity various and microorganism
population. The Fungi are important instrument in the process of decomposition
of organic material for all types of soil. The fungi selulolitic have the ability to
hydrolyze the cellulose naturally through its cellulose activity. This research aims
to study the presence of selulolitic fungi contained on land under forest stands are
former eruption of Sinabung Mount in Karo and soil chemical properties that
influence its existence. Soil sampling is done with diagonally composite. Soil
samples exposed to the eruption consisted of two samples that volcanic ash with a
depth of 0-5 cm and mixed with volcanic ash soil to a depth of 5-20 cm, while for
the control of soil samples consisted of a sample of the soil to a depth of 0-20 cm.
The isolated of fungi and identified in the laboratory of Soil Biology,
Agroekotecnology, Faculty of Agriculture, University of North Sumatra. This
research was carried out start from March 2015 until May 2015. The results
showed that there were several types of selulolitic fungi found in soil samples
affected by volcanic ash and are not affected by volcanic ash (control), namely
Aspergillus sp., Penicillium sp., Rhizopus sp. and Trichoderma sp. | en_US |
