Abstract

The goal of this research is to know the diversity of Arbuscular Mycorrhizal Fungi on Tri Dharma Forest University of North Sumatra. The samples of soil and roots of plants taken from the land of Tri Dharma Forest University of North Sumatra. This research use soil separating method to obtain spores and root coloring method to find out root colonization.The results show that an increase in the average density of spores from the field on the results of trapping, for the percentage of Arbuscular Mycorrhizal Fungi colonization in the roots of plants at 56,5% include grade 4 or high categories. Found 2 genus, namely Genus Acaulospora and Genus Glomus. Of the field found as many as 20 types of spores by average spore density 27 spores/50 g soil and trapping results are found as many as 26 types of spores by average spore density 102 spores/50 g soil.Key words: Mycorrhizal Fungi Fungi, Tri Dharma Forest

Abstract

Volcanic dust expelled while eruption have 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 it’s cellulose activity. This research aims to study the presence of selulolitic fungi contained on land under forest stands are former eruption of Sinabung Mountain in Karo District. Soil sampling was done with diagonally composite. Soil samples exposed to the eruption consisted of two samples that volcanic dust with a depth of 0-5 cm and mixed with volcanic dust 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 isolation of fungi and identification were done in the laboratory of Soil Biology, Agroecotechnology, Faculty of Agriculture, University of Sumatera Utara. This research was carried out from March 2015 until May 2015. The results showed that there were 4 types of selulolitic fungi found in soil samples affected by volcanic dust and are not affected by volcanic dust, namely Aspergillus, Penicillium, Rhizopus, and Trichoderma.Keywords : volcanic dust, former eruption land, cellulose, selulolitic fungi

Abstract

The activity of mining has negative effects to the soil both physical, chemical, and biological. In Physically the structure of the soil, its texture, and porosity will be broken. Mine waste (Tailing) will influence in plant growth because the tailing contained mercury (Hg), lack of micro and macro nutrition and lack of organic substances. Reclamation activities are needed. As a starting point on reclamation, it is a need to be known what locally ground cover which can live in a mining field will be recommended to be planted. This research purposing on knowing what the type of ground cover vegetation which exist on field area of ex civillian gold mining in Kecamatan Naga Juang Kabupaten Mandailing Natal, knowing soil chemical condition for parameter pH, organic-C, available-P, KTK, choose cover vegetation potential for reclamation actifity. Vegetation data collection done in 20 m x 20 m plot purposively arranged, then the K (density), KR (relative density), F (frequency), FR (relative frequency), and INP (important value index) will be analyzed. Result of the research showing that there are 23 type of ground cover vegetation; Paspalum conjugatum, Micania micrantha, Acmella uliginosa, Paspalum comemersorili, Ageratum conyzoides, Crassocephalum crepidioides, Bidens sp, Sida rhombifolia, Solanum torvumn, Ipomea hederaceae, Diplazium esculentum, Calopogonium mucunoides, Borreria sp, Centrosema pubescens, Andropagu aciculatus, Borreria laevis, Amaranthus sp, Cucumis sp, Colocasia esculenta, Chrysopogon sp, Physalis anguleta, Urena lobata, Polygala paniculata. Condition for parameter pH: somewhat acid, organic-C: low, available-P: moderate, KTK: moderate. From those 23 type, there are 5 ground cover potential as pioneer plant based on the highest INP; Paspalum conjugatum (INP: 73,108), Micania micrantha (INP: 36,757), Acmella uliginosa (INP: 10, 968), Paspalum comemersorili (INP: 10,067), Ageratum conyzoides (INP: 9,016). Keywords: gold mining, field reclamation, ground cover

Abstract

The mycorrhizal is affected by biotic and abiotic factor. The purpose of this research is to explore the mycorrhizal on the soil of former gold mine community in Mandailing Natal so that we know the types of native mycorrhizal of the area. The data got from this research used to helps land reclamation efforts by the application of mycorrhizal on land mine. This activity will improve the condition of the damaged environment or increase productivity of the land. This research use soil separating method to obtain spores and root coloring method to find out root colonization. Result from this research is 2 genus spores are found they are genus Acaulospora 5 types of spores / 10 g soil and genus Glomus 11 types of spores / 10 g soil. The percentage of mycorrhizal colonization on former gold mine community in  Mandailing Natal is revolve between 8,12% - 28,55% .Key words: Mycorrhizal, genus Acaulospora and genus Glomus, former gold mine land community
