Kelimpahan Fauna Tanah dan Hubungannya dengan Karakteristik Tapak pada Vegetasi Submontana di Taman Nasional Gunung Gede Pangrango

Fauna tanah merupakan komponen biotik tanah sebagai bioindikator kesuburan. Perbedaan ketinggian di Taman Nasional Gunung Gede Pangrango diduga mempengaruhi kelimpahan fauna tanah. Penelitian bertujuan mengidentifikasi perbedaan kelimpahan mesofauna dan makrofauna tanah di lokasi penelitian dan menganalisis hubungan faktor klimatis serta edafisnya. Analisis vegetasi dilakukan pada petak contoh 20 m x 20 m yang ditempatkan secara purposive sampling pada ketinggian 1.250, 1.350, 1.450 m dpl dan lahan terbuka (1.200 m dpl). Pengambilan sampel tanah dan pengukuran faktor lingkungan dilakukan pada sub-petak contoh berukuran (1 m x 1 m). Hasil uji beda kelimpahan fauna tanah menunjukkan bahwa pada lokasi 1.250 dan 1.450 m dpl tidak berbeda nyata, 1.350 m dpl dan lahan terbuka menunjukkan perbedaan nyata. Kelimpahan fauna tertinggi terdapat pada lokasi 1.350 m dpl (265 individu/m2). Kelimpahan fauna terendah ditunjukkan pada lahan terbuka (11 individu/m2). Hubungan kelimpahan fauna tanah dengan faktor klimatis berupa suhu lingkungan dan intensitas cahaya memiliki nilai korelasi negatif, sedangkan kelembaban menunjukkan nilai korelasi positif. Faktor edafis seperti pH, Kapasitas Tukar Kation, memiliki nilai korelasi negatif dengan kelimpahan fauna tanah, sedangkan berat serasah, respirasi dan porositas tanah menunjukkan nilai korelasi positif. Kata kunci: edafis, fauna tanah, kelimpahan, klimatis, submontanaSoil fauna is a biotic soil component that can be used as fertility bio-indicators. This altitude difference is thought to affect the soil fauna. This research aims to identify differences in the abundance of soil mesofauna and macrofauna at the study site and to analyze the relationship between climatic and edaphic factors. Sampling measuring 20 m x 20 m was placed by purposive sampling at 1.250, 1.350, 1.450 m asl, and open area (1.200 m asl) for vegetation analysis and subplots were carried out by purposive sampling on three sample subplots measuring (1 m x 1 m) for soil samples and environmental factors. The highest soil fauna was found at an altitude of 1.350 m asl (265 individual / m2) and the lowest was in the open area (11 individual / m2). The different test results showed that the altitude of 1.250 and 1.450 m asl was not significantly different, while the altitude of 1.350 m asl and in open area showed a significant difference. The relationship between the population of soil fauna and climatic factors such as ambient temperature and sunlight intensity has a negative correlation value, while humidity shows a positive correlation value. Edaphic factors such as pH, and cation exchange capacity, have negative correlation, while litter weight, respiration, and soil porosity show positive correlation values.
