Title : The Lichen Type Identification as a Bioindicator of Air Quality of Sukolilo District In Surabaya, Indonesia

Abstract :

Bioindicators are organisms or biological responses that indicate the entry of certain substances in the environment. Lichen (Moss Crust) is an indicator plant that is sensitive to air pollution. One of methods to determine the condition of pollution in an area is to look at the macroscopic appearance of Lichen (moss crust) attached to trees or rocks in an area. The aim of this research is to investigate the level of air pollution in Sukolilo District, Surabaya, Indonesia using a bioindicator (lichen). A total of 7 villages (Klampis Ngasem, Menur Pumpungan, Nginden Jangkungan, Gebang Putih, Semolowaru, Medokan Semampir, Keputih) in Sukolilo District were selected as sampling points. Two methods are used to determine air quality in Sukolilo District, namely by biomonitoring the presence of Lichen as well as by measuring the size of Lichen found. Data analysis was performed by identifying the results of both methods with the The Hawksworth and Rose Index indicator table to determine air quality. The results showed that there were two types of Lichen identified in Sukolilo District, namely Lichen Crustose and Folilose with an average size of Lichen 4-6 cm. So it can be concluded that air quality based on the presence of Lichen is classified as Poor and air quality based on Lichen's size is classified as moderate. Therefore, it is concluded that the level of air pollution can be measured by using a Lichen bioindicator
