Abstract

Tumbuhan paku adalah tumbuhan perintis yang dapat ditemukan di setiap tipe kawasan hutan dan memegang peranan penting dalam menyusun ekosistem hutan. Kawasan hutan dapat mengalami perubahan fungsi yang antara lain diakibatkan oleh perbedaan kondisi di tepi hutan dengan di dalam hutan. Dampak dari bertemunya dua kondisi lingkungan yang berbeda tersebut terhadap tumbuhan dan hewan dapat disebut efek tepi (edge effect). Penelitian dilakukan di Cagar Alam Bantarbolang Pemalang, Jawa Tengah. Tujuan dari penelitian ini untuk mengetahui keanekaragaman dan faktor lingkungan tumbuhan paku terestrial di Cagar Alam Bantarbolang. Data yang diperoleh dianalisis menggunakan Indeks Nilai Penting (INP), Indeks Keanekaragamaan (H’) Shannon-Wiener, Indeks Kemerataan Spesies (e), dan Indeks Kesamaan Komunitas (IS). Hasil penelitian di Cagar Alam Bantarbolang diperoleh tumbuhan paku terestrial sebanyak 10 spesies yang terdiri dari 400 individu termasuk dalam 6 familia. Spesies yang paling banyak ditemukan yaitu Stenochlaena palustris dengan 205 individu. Cagar Alam Bantarbolang dipengaruhi oleh efek tepi, karena semakin ke dalam hutan jumlah spesies tumbuhan paku terestrial semakin sedikit. Faktor lingkungan yang berpengaruh terhadap jumlah spesies tumbuhan paku terestrial yaitu suhu, intensitas cahaya dan pH tanah.

Abstract

Wild flowering plants that are included in the understorey are plant communities that make up lower stratification near the surface of the ground. Effects of forest boundaries can be seen from gradual changes in microclimates and vegetation patterns from the edge of the forest to the forest. The impact of meeting these two different environmental conditions for plants and animals is called edge effect. Forest boundaries also have an impact on changes in environmental factors including temperature, humidity, light intensity, soil pH and canopy cover. These factors are thought to influence the diversity of wild flowering plants. The results of the study showed that there were 43 species of wild flowering plants in Bantarbolang Nature Reserve with a total of 978 individuals included in 22 families. The most common type is Piper caducibrachteum as many as 183 individuals. The edge effect has an effect on the diversity of wild flowering plants as evidenced by the increasing number of species obtained tends to be less. Wild flowering plants that have the highest index of importance are Piper betle (66.55%) followed Piper caducibrachteum (52.44%) and Ageratum conyzoides (46.17%). The most influential environmental factors in wild flowering plant diversity are light intensity. The intensity of the light getting deeper into the forest is lower because the sunlight entering the forest is blocked by tree canopies.
