Kurniati C, Irwanto RR. 2015. Evaluation on APTI and API values of Swietenia macrophylla and Agathis dammara in ITB Ganesha Campus, Bandung. Pros Sem Nas Masy Biodiv Indon 1: 1610-1614. The vegetations of various forms of life, such as trees, shrubs, and herbs contribute to create the function and ecological benefits and improve the environment. Each species of plant have different susceptibility to air pollution. This study was conducted to evaluate APTI (Air Pollution Tolerance Index) and API (Anticipated Performance Index) of Swietenia macrophylla and Agathis dammara growth in Campus ITB, Ganesha. Singh and Rao (1983) have developed the Air Pollution Tolerance Index (APTI), which is based on four biochemical properties of leaves i.e ascorbic acid, total chlorophyll, relative water content and pH leaf extract. Based on APTI index, the various plant species can be grouped as tolerant plants (APTI grades 30-100), intermediate tolerant plants (APTI grades 17-29), and highly sensitive plants (APTI grades < 1). API (Anticipated Performance Index) measured based on APTI index add by biological and socio-economic characters. The results showed that APTI value of S. macrophylla was 7,02, while APTI value of A. dammara was 8,54. Therefore, those plants can be grouped as sensitive plant species. API value of S. macrophylla was 41,18% so can be categorized as poor performers. API value of A. dammara was 54,94% so can be categorized as moderate performers.
