RIONALDO MELVIN SILALAHI: Keberadaan Fungi Selulolitik pada Tanah Bekas Kebakaran di Kabupaten Samosir, Sumatera Utara. Dibawah bimbingan DELVIAN dan DENI ELFIATI.
Penelitian ini bertujuan untuk mempelajari keberadaan fungi selulolitik pada tanah bekas kebakaran di Kabupaten Samosir serta sifat kimia dan biologi tanah yang mempengaruhi keberadaannya. Penelitian dilakukan di Laboratorium Biologi Tanah dan Laboratorium Sentral, Fakultas Pertanian, Universitas Sumatera Utara, dimulai dari Oktober 2013 sampai Januari 2014. Sampel diambil berdasarkan 5 kelompok yaitu: Kontrol (yang tidak terbakar), tanah dari bekas kebakaran tahun 2010, 2011, 2012, dan 2013. Hasil analisis sifat kimia termasuk dalam kategori rendah dan jumlah dari total mikroorganisme tanah pada sifat biologi tanah yaitu 100,68 x 103 SPK/ml. Hasil pengamatan secara makrokopis dan mikrokopis yaitu pada sampel K T1P1, K T1P3, K T1P4, K T2P5, 10 T1P1, 10 T1P4, 10 T2P3, 11 T2P2, 11 T2P5, dan 12 T2P5 menunjukkan bahwa fungi selulolitik termasuk dalam genus Aspergillus.

RIONALDO MELVIN SILALAHI: The Existence of Cellulolytic Mushroom on
Land of Former Fires in Samosir Regency, North Sumatra. Under guidance of
DELVIAN and DENI ELFIATI.
This research aims to study the presence of cellulolytic mushroom on land of fire in Samosir Regency as well as chemical and biological soil properties that affect its existence . The study was conducted at the Laboratory of Soil Biology and Central Laboratory , Agriculture Faculty, University of North Sumatra, starting from October 2013 until January 2014 . Samples were taken based on 5 groups: control ( unburned ), the land of the former fires in 2010 , 2011, 2012 , and 2013. The results of the analysis of chemical properties are included in the low category and the total number of soil microorganisms on the biological properties of the soil that is 100.68 x 103 SPK / ml . Observations in makrokopis and mikrokopis for the K sample T1P1 , T1P3 K , K T1P4 , T2P5 K , 10 T1P1 , T1P4 10 , 10 T2P3 , T2P2 11 , 11 T2P5 , and T2P5 12 showed that cellulolytic mushroom belonging to the genus Aspergillus .
