Liken Lobariaceae Sebagai Bioindikator Pencemaran Udara di Balai Konservasi Kebun Raya Cibodas

Abstract

Lichen is a natural bioindicator agent that is often used as an air pollution alarm. The conservation center of the Cibodas Botanical Garden (CBG) is a nature reserve with the type of exitu conservation. Lichen as a biodiversity that is rarely researched is very much found in the KRC Conservation Center. The purpose of the study is to create a digital track record of the Lobariaceae family for 10 years which is presented quantitatively.. The research was conducted from May 2014 – May 2024. The observed likens of the Lobariaceae family are Lobaria pulmonaria, L. retigera, Pseudocyphellaria argyracea, P. crocata, P. aurata and Sticta. The discovery point of L. pulmonaria increased by one point, namely on the trunk of the Araucaria angustifolia tree, P. argyracea increased by two points, namely the trunk of the Rhadermachera and Lithocarpus pallidus, Sticta there was no addition of the discovery point. The result of a talus transplant that survived up to 10 years, namely L. pulmonaria with an indicator that had a talus size twenty times with the original size of 1 cm2 to ± 20 cm2. The results of the transplantation of talus P. crocata and Sticta did not survive, so further transplantation for L. pulmonaria can be attempted to remain sustainable. The conclusion of the study was that L. pulmonaria is a talus that can be propagated to increase air pollution bioindicator agents, Pseudocyphellaria is the most resistant to air pollution, Sticta is the most sensitive to pollution.
