IDENTIFIKASI MAKROFAUNA DIBAWAH TEGAKAN BALANGERAN (Shorea balangeran Burck) DI KHDTK TUMBANG NUSA KALIMANTAN TENGAH

Abstract

Macrofauna is soil fauna that has a body diameter of 2-20mm. In general, macrofauna plays a major role in the decomposition process, carbon flow, nutrient redistribution, bioturbation and soil formation. This research aims to, Identify types of soil macrofauna in Balangeran stands, Analyze the distribution of soil macrofauna in Balangeran stands, and Calculate the soil macrofauna diversity index in Balangeran stands in KHDTK Tumbang Nusa, Central Kalimantan. This research uses a purposive sampling technique to determine observation points, so that they can be representative conditions to achieve research objectives, then identify the types of soil macrofauna using the Pitfall Trap and Hand Sorting methods as well as measuring soil pH, air humidity and air temperature, and then analyzed using the calculation of the Importance Value Index, Species Diversity Index and Species Evenness Index. This research was conducted under Balangeran stands in KHDTK Tumbang Nusa, Central Kalimantan, Jabiren Raya District, Pulang Pisau Regency, Central Kalimantan Province. The macrofauna found under the Balangeran stand were 17 species from 15 families with a total of 105 individual macrofauna. The level of macrofauna control under the Balangeran stand has the highest types of INP values, namely red ants (18.1%) and spiders (31.76%). The diversity index in soil macrofauna under the Balangeran stand is absolute (medium) with a value of 2.592.
