Air pollution is one of the main issues faced by urban areas. Therefore, morphological characteristic and colony coverage of lichen growing at different scale air-polluted area could become as a bioindicator of their air quality. This research aims to determine the condition of lichen in spots located at near and far from the main road (width ± 29 meter) in urban area at Banjarbaru town. This research used descriptive method with purposive sampling technique. Sample were obtained from 2 plots those were far and near the main road, each plot represented by samples from 5 different trees (densed canopy with minimum DBH at 25 cm). Lichens were taken at 50-150 cm above ground level using 20x20 cm quadrant plastic frame. Observation variables include the number and shape of colonies, color and type of thallus, and percentage of thallus cover. We determined 13 colonies from spots far from the main road (500-600 meter from main road). Lichen dominated by green to bluish color, thallus consist of crustose and foliose, and the average percentage of thallus cover was 28.01%. While from that near the main road (14-250 meter from main road), we determined 14 colonies predominantly consisted of white crustose lichens, and the average percentage of thallus cover was 10.01%. Traffic intensity showed to have significant effect on lichens community. The main difference can be seen from morphology and colony coverage. Based on this result, lichen can be used as bioindicator of air quality, especially air pollution caused by motorized vehicles. Keywords arboretum, crustose, foliose, pollution, thallus
Ulasan mengenai kualitas air dari hasil penelitian di Pulau Jawa dan Kalimantan telah dilakukan untuk mendapatkan ilustrasi mengenai tingkat pencemaran air (air minum isi ulang, air PDAM, dan air sumur) oleh bakteri Coliform. Data diperoleh dari sumber sekunder berupa hasil penelitian dari beberapa daerah di Pulau Jawa dan Kalimantan. Hasil perbandingan kualitas air dari kedua pulau disajikan dalam bentuk persentase. Berdasarkan hasil yang ada, tingkat pencemaran air di Pulau Jawa lebih tinggi dibandingkan Pulau Kalimantan. Persentase rata-rata cemaran Coliform pada air di Pulau Jawa yaitu 61,42% dan hanya sebesar 42,26% di Pulau Kalimantan. Tingginya persentase cemaran air oleh bakteri Coliform di Pulau Jawa dikarenakan Pulau Jawa memiliki keberadaan sumber pencemar yang lebih tinggi. Keberadaan sumber Coliform dipengaruhi oleh jumlah penduduk dan perumahan serta produksi sampah organik.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
