AKTIVITAS MIKROORGANISME PADA TANAH BEKAS ERUPSI GUNUNG SINABUNG DI KABUPATEN KARO
ABSTRACT: Volcanic
ash released when the eruption has an acidic pH, thus affecting the amount and
activity of microorganisms in the soil. Therefore conducted this study to
determine the activity of soil microorganisms in the former eruption of Mount
Sinabung in Karo. Measurement of total soil microorganisms was done by Agar
Cawan method, while the measurement of the activity of soil microorganisms was
conducted jar and titrimetic method. The result of the research showed that the
higher of the pH, the colony of microorganism will be much and the reverse. The
higher of C- organic, the activity of micoorganism will be high within the
soil, and the reverse. Respiration value on land affected by volcanic ash at a
depth of 0-5 cm was 0,96. Respiration value on land affected by volcanic ash at
a depth of 5-20 cm was 1,16. Respiration value on land that was not affected by
volcanic ash was 1,52.
