Keanekaragaman Lichen pada Pohon Peneduh pada Tiga Stasiun Pengamatan di Kota Semarang

---

ABSTRAK

Lichen merupakan simbiosis antara fungi dari kelompok Ascomycetes dan Basidiomycetes, dengan alga dari kelompok Cyanobacteria atau Chlorophyceae. Struktur morfologi lichen tidak memiliki lapisan kutikula, stomata dan organ absorptif. Sensitifitas lichen terhadap pencemaran udara dapat dilihat melalui perubahan keanekaragamannya. Tujuan dari penelitian ini adalah untuk mengkaji keanekaragaman jenis lichen, mengkaji kondisi lingkungan dan pohon peneduh sebagai habitat lichen di Kota Semarang. Penelitian dilaksanakan pada bulan Oktober hingga November 2017 menggunakan metode purposive sampling pada penentuan stasiun pengamatan, penentuan plot sampling serta pemilihan pohon peneduh. Sampling dilakukan di tiga stasiun pengamatan, yakni: Terminal Mangkang, Kawasan Simpang Lima dan Kampus Undip Tembalang. Berdasarkan hasil penelitian di ketiga stasiun pengamatan, diperoleh 18 spesies lichen, 13 spesies berhasil diidentifikasi dan 5 spesies belum teridentifikasi. Lichen yang diperoleh sebanyak 8 famili yakni Arthoniaceae, Caloplacaceae, Physciaceae, Graphidaceae, Lecanoraceae, Lecidellaceae, Leprariaceae dan Parmeliaceae. Jenis lichen tersebut termasuk dalam kelompok talus foliose dan crustose. Nilai indeks keanekaragaman jenis lichen di ketiga stasiun pengamatan yaitu: Terminal Mangkang (1.88), Kawasan Simpang Lima (2.95) dan Kampus Undip Tembalang (3.71). Jumlah jenis dan jumlah individu tertinggi terdapat di Kampus Undip Tembalang, dengan total 17 spesies dan 295 individu lichen. Dirinaria spp. merupakan spesies yang paling banyak ditemukan di ketiga stasiun pengamatan. Pohon peneduh yang paling banyak ditumbuhi lichen adalah Mahoni (Swietenia mahagoni).

ABSTRACT

Lichen is a symbiosis between fungi of the Ascomycetes and Basidiomycetes groups, with algae from the Cyanobacteria or Chlorophyceae groups. The morphological structure of lichen has no cuticle, stomata and absorptive organs. The sensitivity of lichen to air pollution can be seen through their changes in diversity. The purpose of this study is to examine the species diversity of lichens, to examine the environmental conditions and shade trees as habitat for lichens in the city of Semarang. The research was conducted from October to November 2017 using the purposive sampling method in selection of observation stations, selection of sampling plot and selection of shade trees. Sampling was conducted at three observation stations, namely: Mangkang Terminal, Simpang Lima Area and Undip Tembalang Campus. Based on the results of research at the three observation stations, 18 lichen species were obtained, 13 species were identified and 5 species were not identified. Lichen obtained as many as 8 families, they are Arthoniaceae, Caloplacaceae, Physciaceae, Graphidaceae, Lecanoraceae, Lecidellaceae, Leprariaceae and Parmeliaceae. These types of lichen belong to the thallus group foliose and crustose. Diversity index value of lichen types in the three observation stations are: Terminal Mangkang (1.88), Simpang Lima Area (2.95) and Undip Tembalang Campus (3.71). The highest number of species and individuals is at the Undip Tembalang Campus, with a total of 17 species and 295 individuals lichen. Dirinaria spp. is the most found species in all three observation stations. The shade trees that are most overgrown with lichens are Mahogany (Swietenia mahagoni).
