Abstract. Hernowo JB. 2017. Determinant factors of the Javan green peafowl (Pavo muticus muticus) Linnaeus 1758 habitat in Baluran and Alas Purwo National Parks, East Java, Indonesia. Trop Drylands 1: 50-56. There is limited understanding of the factors determining the habitat variables preferred by the Javan green peafowl (Pavo muticus muticus Linnaeus, 1758). Baluran National Park (BNP) and Alas Purwo National Park (APNP) in East Java, Indonesia are habitats of the natural distribution of the Javan green peafowl population. While they occur on various types of habitat (e.g. savanna, beach forest, and monsoon forest in BNP; and grazing area and intercropping teak plantations in APNP), it is not clear what environmental factors affecting their abundance. This research aimed to investigate the determinant factors of Javan green peafowl habitat in correlation with food, water, roosting, shelter, and nesting site. The Principal Component Analysis (PCA) was used to analyze determinant factors of habitat components. The results showed that the determinant factors of the Javan green peafowl habitat in BNP were the density of shelter, the density of food, the number of roost trees and the height of roost trees. Meanwhile, in APNP, the determinant habitat factors were the number of roost trees, the height of roost trees, and the number of continuously available water. The findings of this study highlight the importance of preserving and maintaining the discriminant components of the habitat of the Javan green peafowl in BNP and APNP.
