Abstract

Paku litofit adalah salah satu jenis paku yang biasa ditemukan di dinding lembab bangunan perkotaan. Kemampuan paku untuk hidup di wilayah urban kemungkinan didukung oleh karakter perkembangbiakannya. Dalam satu kotak spora mengandung banyak spora yang dapat terbang dan menyebar ke tempat baru. Sebagian dari spora urban mungkin akan terdeposisi di dinding bangunan. Penelitian ini bertujuan untuk mengetahui nama jenis spora, jumlah jenis spora, dan frekuensi jenis spora paku pada sampel dari tiga macam dinding di kawasan BUPERTA Cibubur. Dinding diambil sebanyak 90 sampel dinding dan dibagi menjadi tiga kategori; dinding bercat, dinding tidak bercat, dan dinding berlumut. Penelitian dilakukan dari bulan September-Desember 2021 di Laboratorium Struktur Perkembangan Tumbuhan UNJ dan Kawasan BUPERTA Cibubur. Metode yang digunakan adalah metode deskriptif dan pengambilan data dilakukan dengan teknik purposive sampling. Dari pengamatan mikroskop dengan perbesaran 400x, didapatkan hasil adanya 4 jenis spora dari total 90 sampel dinding. Spora yang ditemukan adalah spora Nephrolepis biserrata, Ophioglossum sp., Lepisorus mucronatus, dan Platycerium bifurcatum. Frekuensi tertinggi dipegang oleh Nephrolepis biserrata dengan total 7% dan sporanya ditemukan di 6 dinding sampel, spora Ophioglossum sp. ditemukan di 2 dinding sampel, spora Lepisorus mucronatus dan Platycerium bifurcatum ditemukan di 1 dinding sampel. Tidak ada perbedaan frekuensi spora pada dinding setelah dilakukan uji chi-square. *********************************** Lithophytic ferns are one of the most common types of ferns found on the damp walls of urban buildings. The ability of ferns to live in urban areas is probably supported by their reproductive characteristics. In one spore box contains many spores that can fly and spread to new places. Some of the urban spores may be deposited on the walls of the building. This study aims to determine the species name of spores, the number of species of spores, and the frequency of the fern spores in samples from three types of walls in BUPERTA Cibubur area. The research was conducted from September to December 2021 at the Plant Development Structure Laboratory of UNJ and Cibubur BUPERTA area. The total number of samples is 90 walls and divided into 3 categories; painted walls, unpainted walls, and mossy walls. The method used is descriptive method and data collection is done by purposive sampling technique. From observations with a microscope with a magnification of 400x, it was found that there were 4 types of spores from a total of 90 samples of walls with 3 types of walls. The spores found were spores of Nephrolepis biserrata, Ophioglossum sp., Lepisorus mucronatus, and Platycerium bifurcatum. The highest frequency was held by Nephrolepis biserrata with a total of 7% and its spores were found in 6 sample walls, Ophioglossum sp. found in 2 sample walls, spores of Lepisorus mucronatus and Platycerium bifurcatum were found in 1 sample wall. There wasno difference in the frequency of spores on the wall after the chi-square test was performed.
