Biodiversities and Dynamics of Soil Macrofauna in Pekalongan, Central Java, were documented. Five land uses were studied i.e. tea (Camellia sinensis) plantation, coffee (Cciffe canephora) plantation, corn (Zea mays L.) plantation, clove (Eugenia aromatica O.K.) plantation and sengon (Paraserianthes falcataria L. Nielson) stand. The aims were to clarify the effect of land use patterns on population and diversity of soil macrofaunas and their dynamics related to the different land use systems. The study was done by using monolith of 25 cm x 25 cm in size, vertically divided into 4 layers-depth; organic layer, 0-10 cm, 11-20 cm, and 21-30 cm depth. All macrofauna found in the monoliths were identified, and counted. The collected data were analyzed using index of diversity, index of important value, statistic-F test and LSD test. Result showed that Arachnid and some ordo of Hexapods (Orthoptera, Coleoptera, Diptera, Lepidoptera dan Hymenopterc) were found very significant on soil surface and in organic layer. Where as in deeper soil layer only Oligochaeta dominated. The biodiversity tend to be lower with the increasing soil depth. The changes of types of land uses from traditional pattern to tea plantation will generally lower the biodiversity, especially in organic layer and in 0-10 cm soil depth. The number of soil macrofauna on tile surface and organic layers were fluctuated along the year; as shown by Arachnids and some ordo of Hexapods which were significant. Although some macrofauna in the soil relatively more stable. Biodiversity in all strata tend to be lower early in rainy season and then increase gradually toward the end of rainy season.
