KEANEKARAGAMAN MAKROINVERTEBRATA PADA LAHAN GAMBUT SEBAGAI BIOINDIKATOR KUALITAS TANAH PERKEBUNAN KELAPA SAWIT DI KABUPATEN PULANG PISAU DAN KAJIAN IMPLEMENTASI SEBAGAI SUMBER BELAJAR

Oil palm is one of the plantation commodities and sources of foreign exchange, employment, and a source of welfare for farmers and planters. The rapid development of the oil palm plantation industry has led to increasingly limited agricultural productive land, the limitation of this productive land has caused extensification to marginal lands. Peat land is one of the marginal lands chosen mainly by large companies because of its relatively rare population so that the possibility of conflicts related to land use is relatively small.Continuous land use change will reduce soil nutrient availability and cause damage to the physical, chemical, and biological conditions of the soil so that soil fertility will decline, one way to see changes in a community or ecosystem is to use a bioindicator, one of which is land macroinvertebrates. the easiest to learn. The purpose of this study was to determine the soil biodiversity of macroinvertebrates on peatlands to be used as bioindicators of soil quality, which was associated with soil physical and chemical factors to be used as a study of high school biology learning resources. The type of research used was descriptive quantitative, the study was carried out on an oil palm plantation owned by PT SCP in Pulang Pisau District, Central Kalimantan, the sampling technique used was incidental sampling using plot method and hand sorting The data analysis technique used in this study is the personnel correlation to find out the relationship between soil macroinvertebrates and abiotic factors. The results showed that the types of macroinvertebrates found were Iridomyrmex, Armadillidium, Sellnickochthonius, Rhytidoponera, Dysderella, Porcellio, and Myrmica, and there was a significant correlation between abiotic environments (pH, temperature, water content) with sig values> 0.0
