Kelimpahan Makrofauna Tanah pada Beberapa Tutupan Lahan di Kabupaten Balangan, Provinsi Kalimantan Selatan
Abstract
Keberadaan makrofauna tanah memiliki peran penting dalam
mempertahankan dan mengembalikan kesuburan tanah. Penelitian ini bertujuan
menganalisis kelimpahan makrofauna tanah dan pengaruh jenis vegetasi, serta
lingkungan terhadap kelimpahan makrofauna tanah pada beberapa tutupan lahan di
Kabupaten Balangan, Kalimantan Selatan. Pembuatan petak dengan ukuran 20 m ×
20 m secara purposive sampling. Analisis data dilakukan dengan uji Beda Nyata
Terkecil (BNT) dan uji korelasi Pearson. Kelimpahan makrofauna tanah secara
keseluruhan terdiri atas 15 ordo dan 27 famili dengan total individu sebanyak 370
individu/m². Hasil uji BNT menunjukkan kelimpahan makrofauna tanah berbeda
nyata di hutan sekunder dan lahan kosong, sedangkan kelimpahan makrofauna
tanah tidak berbeda nyata antara hutan meranti dan kebun karet. Berdasarkan uji
korelasi Pearson, faktor klimatis kelembapan tanah memiliki hubungan positif yang
sangat kuat terhadap kelimpahan makrofauna tanah, serta faktor edafis seperti
porositas, C-organik, respirasi, berat basah, berat kering, dan kadar air juga
memiliki hubungan positif yang sangat kuat terhadap kelimpahan makrofauna tanah. The existence of soil macrofauna has an important role in maintaining and
restoring soil fertility. This study aimed to analyze the abundance of soil
macrofauna and the influence of vegetation type, as well as the environment on the
abundance of soil macrofauna in several land covers in Balangan Regency, South
Kalimantan. Plots measuring 20 m × 20 m were made using purposive sampling.
Data analysis used the Least Significant Difference (LSD) test and Pearson
correlation test. The overall abundance of soil macrofauna consists of 15 orders and
27 families with a total of 370 individuals/m². The BNT test results showed that the
abundance of soil macrofauna was significantly different in secondary forests and
empty land, while the abundance of soil macrofauna was not significantly different
between meranti forests and rubber plantations. Based on the Pearson correlation
test, the climatic factor of soil moisture has a very strong positive relationship with
the abundance of soil macrofauna, and edaphic factors such as porosity, C-organic,
respiration, wet weight, dry weight, and moisture content also have a very strong
positive relationship with the abundance of soil macrofauna.
