Identifikasi Makrofauna Tanah pada Beberapa Jenis Vegetasi Penutup (Ground Cover) di Area Hutan Pinus dan Kebun Jeruk, Wana Wisata Alam Bedengan, Kecamatan Dau-Malang
The purpose in this study was to determine the composition of plant structure, macro-fauna structure and the relationship between diversity and soil organic content on some types in the ground cover pinus forest area and orange garden.
Pinus was known to produce allelopathic substances that could inhibit the growth other plants. However, some types of plants classified on the ground cover has been ability to survive in that condition. The ground cover has an important role because it can improve soil quality.The aims of this study to determine the structure of plant composition, soil macrofauna and relationship soil macrofauna with soil organic content.
The research was implemented in Wana Nature Bedengan, district Dau-Malang and Ecology Laboratory of Brawijaya University-Malang. The research was performed on four areas of ground cover each on area pinus-ayapana, pinus-semanggi gunung, pinus-rumput gajah, and orange garden. The data was collected by direct observation and sampling. The Data was analyzed by using the Importance Value Index (INP) and diversity index (HI).
The results of the composition of plant structure on some types in the ground cover pinus forest area and orange garden including; a). Pinus-Ayapana area was dominated by Ayapana triplinervis, Oxalis triangularis, and Mimosaceae, b). Pinus-Semanggi Gunung was dominated by Oxalis triangularis, Mimosa pudica, and Poaceae, c). Pinus-Rumput gajah area was dominated by Pennisetum purpureum, Cyperus rotundus and Artimesia sp, d). Orange garden area was dominated by Asteraceae, Comelinna difusa, dan Kylinga monocephala.
The composition of soil macrofauna structure on some types in the ground cover pinus forest area and orange garden including; a). Pinus-Ayapana area was dominated by Collembola, Formicidae, Gastropoda dan Araneidae, b). Pinus-Semanggi Gunung was dominated by Oligochaeta, Chilopoda, dan Formicidae, c). Pinus-Rumput gajah area was dominated by Oligochaeta and Formicidae, d). Orange garden area was dominated by Formicidae, Gastrophoda, and Oligochaeta. The high diversity of soil makrofauna positively correlated with soil organic content.
