Pengaruh Dosis Biofertilizer Formulasi Terhadap Kelimpahan Zoobenthos Dalam Media Tanah Gambut
This research was conducted in March-April 2018 at the Peatland of
Kualu Nenas Village, Tambang, Kampar, Riau. Method of this research was
experimental method Complecetly Recommend Design (CRD) using 1 factor and
5 level of treatment (P0 without biofertilizer : control, P1: 300 g/m3, P2: 450 g/m3,
P3: 600 g/m3 and P4:750 g/m3). The best treatment in this research for increasing
abundancy of microzoobenthos was 750 g/m3 (P4) and for macrozoobenthos was
600 g/m3 (P3). The diversity index (H') value for macrozoobenthos was 1.60 and
the dominance value (C) was 0.53. The diversity index value (H') for
macrozobenthos was 1.90 and the dominance value (C) was 0.41. As for water
quality which includes temperatures ranging from 23-37 oC, pH ranges from 6-
7.5, DO ranges from 3.2-8.6 mg / L, nitrates range from 0.76-22.7 mg / L,
phosphates range from 1.41-3.91 mg / L.
