Abstract

Komunitas fauna tanah merupakan bagian dari ekosistem tanah yang kehidupannya dipengaruhi oleh berbagai faktor lingkungan yaitu faktor biotik dan faktor abiotik. Faktor biotik salah satunya meliputi kondisi vegetasi, sedangkan faktor abiotik dapat meliputi kondisi iklim dan kondisi tanah. Tumbuhan atau vegetasi merupakan jembatan antara ekosistem yang ada di atas dan di dalam tanah, oleh karena itu menurut Tilman (2001) perubahan keragaman vegetasi tentu saja akan mengubah fungsi ekosistem di atas dan di dalam tanah. Tujuan dari penelitian ini adalah untuk mengetahui struktur komunitas fauna tanah berdasarkan tipe vegetasi yang berbeda di Taman Safari Indonesia II, Prigen Jawa Timur. Metode yang digunakan adalah Pitfall Trap dan Barlese Tullgren Funnel. Faktor lingkungan yang diukur meliputi faktor biotik (analisis vegetasi) dan abiotik (suhu tanah,kelembaban tanah, pH tanah, intensitas cahaya, kadar NPK serta C organik). Analisa data menggunakan metode deskriptif kuantitatif, metode ordinasi dengan menggunakan program Canoco for Windows 4.5. Hasil penelitian menunjukkan bahwa hutan campuran memiliki struktur komunitas fauna tanah yang lebih stabil dengan memiliki keanekaragaman spesies (H’) yang paling tinggi, kemerataan spesies (E) yang lebih merata dan dominansi spesies (C) yang paling rendah. Kesamaan komunitas fauna tanah (CMH) tertinggi terdapat di hutan Pinus dan hutan campuran serta beberapa spesies fauna tanah terbukti dipengaruhi oleh parameter fisika dan kimia lingkungan tertentu ============================================================================================= Soil fauna community is part of the soil ecosystem whose lives are influenced by various environmental factors including biotic and abiotic factors. One of the examples of biotic factors is the condition of vegetation, while the abiotic factors include climatic conditions and soil conditions. Plants or vegetation are a bridge between the existing ecosystem above and inside the soil, therefore, according to Tilman (2011) the changes in vegetation diversity will change the function of ecosystem above and inside in the soil. The purpose of this research was to determine coummunity structure of soil fauna by different vegetation types in Taman Safari Indonesia II Prigen East Java. The method that use is Pitfall traps and Barlese tullgren funnel. The measured environmental factors include biotic factors (analysis of vegetation) and abiotic factors (soil temperature, soil moisture, soil pH, light intensity, levels of NPK and organic C). The data was analyzed by using descriptive methods and ordinative methods by using Canoco program for Windows 4.5. The result showed that the mixed forests have soil fauna community structure more stable by having the highest species diversity (H’) , the more equitable species evenness (E) and the lowest dominance of species (C). The similarity of the highest soil fauna communities (CMH) is in the pine forest and mixed forests as well as several species of soil fauna is shown to be affected by physical and chemical parameters of specific environment.
