Daftar Isi:
- Timber harvesting activities generally use heavy equipment which has an impact on the ecological aspects, one of which is damage to the soil. Damage to the soil leads to changes in soil biology resulting in reduced or loss of nutrients contained in the soil as well as disruption of the life of biota in the soil which causes reduced fertility in the soil. The purpose of this research is to determine the impact of forest harvesting on the biological properties of soil in the plot of 10D RPH Rejosari BKPH Sengguruh KPH Malang. This research was conducted in the 10D plot of Rejosari FPR Sengguruh RFMU Malang FMU, Forestry Laboratory and Agrotechnology Laboratory of the University of Muhammadiyah Malang, which was conducted from May to July 2018. The random sampling of soil samples, random sampling of earthworms by hand sorting method and isolation of fungi and bacteria using agar plates. The analysis used is by qualitative, quantitative and descriptive methods. From the research, it was found that there was a decrease in soil organic matter content on the land after harvesting from the rather high to low grade, found three types of worms, namely Pheretima, Pontoscolex, and Microscolex which decrease in individual density at post harvesting from 39,54 individuals/m2 to 16,87 individuals/m2. The total of fungi and bacterial colonies post-harvest experienced a decrease in fungal colonies from 2,54 x 104 CFU / ml to 0,88 x 104 CFU / ml and to bacterial colonies from 22,58 x 105 CFU / ml to 17,6 x 105 CFU / ml.
