TREES PHYSIOLOGICAL RESPONSES TO AIR POLLUTION IN TAMAN MARGASATWA RAGUNAN AND UI DEPOK CAMPUS

Air pollution is a common environmental problem. Planting trees can minimize the adverse effects of air pollution. Plants absorb and accumulate pollutants through stomata. Biochemical changes in leaves will appear as physiological response plants to that be known by calculating APTI (Air Pollution Tolerance Index) value. This study aimed analyze differences responses five tree species Taman Margasatwa Ragunan (TMR) South Jakarta Universitas Indonesia (UI) Depok Campus well find out proper planted areas with high levels The (Hevea brasiliensis, Manilkara kauki, Artocarpus heterophyllus, Ficus septica, Mangifera indica) were used examine effect parameters (relative water content, leaf extract pH, total chlorophyll ascorbic acid content) observed from each species. value parameter was calculated into equation. H. F. M. indica categorized moderately tolerant plants, kauki included intermediate A. heterophyllus sensitive plant both locations. highest values Thus, recommended polluted area indica.
