Penelitian ini bertujuan untuk mengetahui preferensi penempatan mating ring oleh kuau raja (Argusianus argus Linnaeus, 1766) terhadap kerapatan tajuk vegetasi berbasis NDVI dan kelerengan di Stasiun Penelitian Soraya. Metode yang digunakan dalam penelitian ini adalah metode analisis NDVI dan analisis kelerengan. Analisis NDVI dan analisis dilakukan untuk mengetahui preferensi penempatan mating ring berdasarkan kerapatan tajuk vegetasi dan kelerengan, kemudian diolah menggunakan ArcGIS. Penempatan mating ring kuau raja dinilai berdasarkan peluang penempatan pada lima kelas NDVI dan kelerengan di sekitar mating ring. Kelima kelas NDVI tersebut dikelompokkan berdasarkan tingkat kehijauan, yaitu kehijauan tinggi, kehijauan sedang, kehijauan rendah, kehijauan sangat rendah, dan lahan tidak bervegetasi. Sementara kelima kelas kelerengan dikelompokkan berdasarkan kondisi topografi, yaitu datar, landai, agak curam, curam, dan sangat curam. Selanjutnya, distribusi mating ring dilihat berdasarkan penempatannya dalam kelas NDVI dan kelas kelerengan. Hasil penelitian yang diperoleh berdasarkan analisis NDVI menunjukkan bahwa kuau raja (Argusianus argus) lebih cenderung menempatkan mating ring pada wilayah yang memiliki kehijauan tinggi dan analisis kelerengan menunjukkan bahwa kuau raja (Argusianus argus) lebih cenderung menempatkan mating ring pada wilayah yang memiliki topografi landai dan agak curam, diikuti dengan topografi datar.

This study aims to determine the preference for mating ring placements by the great argus (Argusianus argus) on canopy density based on NDVI and slope at the Soraya Research Station. The methods used in this study were NDVI and slope analysis methods. NDVI and slope analyses were carried out to determined the preference for mating ring placements based on canopy density and slope, then processed by using ArcGIS. The placements of the great arguses’ mating rings was assessed based on the their placement in five classes of NDVI and slope around the mating rings. The five NDVI classes are grouped based on the level of greenness, namely high greenness, moderate greenness, low greenness, very low greenness, and non-vegetated land. While the five slope classes are grouped based on topographic conditions, namely flat, sloping, slightly steep, steep, and very steep. Furthermore, the distribution of mating rings was seen based on their placement in the NDVI and slope classes. The results obtained based on NDVI analysis show that the great arguses (Argusianus argus) were more likely to place their mating rings in areas with high greenery and the slope analysis shows that the great arguses (Argusianus argus) was more likely to place their mating rings in areas with gentle and slightly steep topography, and followed by flat topography.
