Karakteristik Morfometrik Collembola Pada Lahan Perkebunan Kelapa Di Kecamatan Tinanggea Kabupaten Konawe Selatan

Abstrak

This research aims to determine the morphometric characteristics and differences in Collembola in coconut plantations with different planting ages in Tinanggea District, South Konawe Regency. The type of research used is quantitative descriptive research using purposive sampling with direct observation and sampling at the research location. Soil samples were collected at each observation station based on three transects, with each transect consisting of five plots. Sampling was conducted using a 5 cm diameter soil ring sampler at a depth of 10 cm, followed by sample extraction using a Tullgren Funnel. Morphometric measurements of Collembola were performed using a Leica DFC310 FC stereo microscope. Environmental parameters measured included light intensity, air temperature and humidity, soil temperature and pH, soil moisture content, and organic matter content. The results of the study showed that there were three dominant Collembola species across each stasiun, namely Cyphoderopsis sp., Folsomia candida, and Folsomides parvulus. Parameters measured included body length (BL), antenna length (AL), and furcula length (FL), with averages: Cyphoderopsis sp. (BL = 0.49 mm; AL = 0.13 mm; FL = 0.17 mm), Folsomia candida (BL = 0.56 mm; AL = 0.10 mm; FL = 0.08 mm), and Folsomides parvulus (BL = 0.74 mm; AL = 0.11 mm; FL = 0.08 mm). The results of the ANOVA test showed that there were significant differences (p-value < 0.05) in the three morphometric parameters of Collembola measured at different plant ages.
