Javanese Edelweis (Anaphalis javanica) is a pioneer plant that has enormous ecological benefits. This plant is living on volcanic ash deposits and crater soils as on Mount Papandayan. The presence of Javanese Edelweis are endangered. This study aims to: (1) compare the density of Javanese Edelweis on Mount Papandayan especially in Tegal Alun, Tegal Bungbrun and Pondok Saladah; (2) knowing the effect of abiotic factors (temperature, light intensity and soil pH) on the density of Javanese Edelweis. The method used in this research is quantitative descriptive research method. Data collection was carried out using the 100 meter belt transect method with a width of 5 meters in three sample locations: Tegal Alun (28 transects), Tegal Bungbrun (3 transects) and Pondok Saladah (10 transects). The results indicate that there is a difference in the density of Javanese Edelweis between TegalAlun, Tegal Bungbrun and Pondok Saladah. The density value in Tegal Alun is 2275.7 trees/hectare, Tegal Bungbrun 946.7 trees/hectare and Pondok Saladah 366 trees/hectare. Whereas for abiotic factors it is known that air temperature, light intensity and soil pH simultaneously influence the density of Javanese Edelweis with R value 85% and influence 70%.
