    (2013-07-17) Putra, Muhammad; Wawan; Wardati
    The purpose of this research is to identify the soil macrofauna, calculate the density of population and determine the potential soil macrofauna for Biotillage. The research was conducted by survey method. The results of the research showed that the soil macrofauna identified on the oil palm circle is the kind of Hymenoptera (ants), Olighochaeta (earthworms), Coleoptera (beetles land), Dermaptera (cecopet), Araneida (spiders), Chilopoda (centipedes), Orthoptera (dog the ground), Strepsiptera (flea dirt) and Blattodea (cockroaches ground). While the soil macrofauna identified on oil palm die path is the kind of Hymenoptera (ants), Olighochaeta (earthworms), Coleoptera (beetles land), Dermaptera (cecopet), Araneida (spiders), Chilopoda (centipedes), Strepsiptera (ticks), Isoptera (termites) and Scorpiones (scorpions). The increasing age of the oil palm obtains decrease in soil macrofauna species, increase in the number of soil macrofauna, increase in the number of all kinds of population density soil macrofauna and the stability relative of the soil macrofauna relative density identified on the oil palm circle and on oil palm die path and led to the correlation caused the soil density level decreased of Ultisols. While the potential soil macrofauna for Biotillage in this research is the kind of Hymenoptera (ants) and Olighochaeta (earthworms).
