Abstract
Spora tumbuhan paku tersimpan dengan baik berada di bawah tanah dan biasanya disebut dengan bank spora. Bank spora terestrial tersebar dan dapat ditemukan di beberapa kemiringan tanah di wilayah urban. Penelitian dilakukan pada tiga variasi tanah yaitu A. 0°– 20°, B. 21°– 40° dan C. 41°– 60°. Bertujuan untuk mengetahui jenis spora paku yang jatuh dan potensi bank spora paku terestrial pada tiga variasi kemiringan tanah di kawasan Bumi Perkemahan Cibubur. Penelitian dilakukan dari bulan September-Desember 2021 di Laboratorium Struktur Perkembangan Tumbuhan UNJ dan Kawasan Bumi Perkemahan Cibubur. Metode penelitian yang digunakan deskriptif dan pengambilan data dilakukan dengan teknik purposive sampling. Sampel tanah sebanyak 90 titik lokasi diambil pada setiap variasi kemiringan tanah yang berbeda, ditempat vegetasi lapangan rumput terbuka. Spora paku diamati menggunakan mikroskop cahaya dengan perbesaran 1000x. Data penelitian di analisis menggunkan uji Chi-Square dan Kruskal Wallis. Jumlah keseluruhan jenis spora paku yang ditemukan pada tiga variasi kemiringan tanah sebanyak 24 jenis. 10 jenis spora paku ditemukan pada kemiringan A. 0°– 20°, 9 jenis spora paku ditemukan pada kemiringan B. 21°– 40° dan 9 jenis spora paku pada kemiringan C. 41°– 60°. Tidak terdapat perbedaan frekuensi keberadaan spora paku pada kemiringan A. 0°– 20°, B. 21°– 40° dan C. 41°– 60° dengan nilai signifikansi lebih dari 0,05. Hasil uji Kruskal Wallis dari kemiringan A. 0°– 20°, B. 21°– 40° dan C. 41°– 60° memiliki perbedaan nilai yang signifikan (Asymp. Sig < 0,05). Kelembapan tidak menentukan banyaknya spora pada kemringan A. 0°– 20°, B. 21°– 40° dan C. 41°– 60°. ************************************** Fern spores are well stored underground and are usually called spore banks. Terrestrial spore banks are scattered and can be found on some slopes in urban areas. The research was conducted on three soil variations, A. 0°– 20°, B. 21°– 40° and C. 41°– 60°. The purpose of this study was to determine the type of fern spore that fell and the potential of terrestrial fern spore bank on three variations of soil slope in Bumi Perkemahan Cibubur area. The research in September-December 2021 at the Plant Development Structure Laboratory of UNJ and Bumi Perkemahan Cibubur Area. The research method used is descriptive and data collection with purposive sampling technique. Soil samples from 90 locations, were taken at each different variation of the slope of the soil, in an open grass field vegetation. The spike spores were observed using a light microscope with a magnification of 1000x. The research data were analyzed using the Chi-Square and Kruskal Wallis test. The total number of types of fern spores found in the three variations of the soil slope was 24 species. 10 types of fern spores were found at a slope of A. 0°– 20°, 9 types of fern spores were found at a slope of B. 21°– 40° and 9 types of fern spores were found at a slope of C. 41°– 60°. There was no difference in the frequency of the presence of fern spores on the slopes of A. 0°– 20°, B. 21°– 40° and C. 41°– 60° with a significance value of more than 0,05. The results of the Kruskal Wallis test of the slopes of A. 0°– 20°, B. 21°– 40° and C. 41°– 60° have significant differences in values (Asymp. Sig < 0.05). Humidity does not determine the number of sporesat a slope of A. 0°– 20°, B. 21°– 40° and C. 41°– 60°.
