Abstrak. Penelitian ini bertujuan untuk mengetahui stomata daun mangga (Mangifera indica) di daerah dengan kondisi lingkungan yang berbeda. Penelitian bersifat deskriptif analisis. Pengambilan sampel dilakukan melalui survey secara acak di Cagar Alam Pananjung Pangandaran dan salah satu ruas jalan di Kecamatan Pangandaran Kabupaten Pangandaran. Paramater yang diamati adalah kerapatan dan kerusakan stomata. Selain itu diukur juga luas daun, berat partikel debu yang menempel di daun, serta beberapa faktor lingkungan fisik seperti intensitas cahaya, suhu, dan kelembaban udara. Hasil penelitian menunjukkan bahwa kerapatan dan kerusakan stomata daun mangga (Mangifera indica) yang tumbuh di pinggir jalan yang banyak dilalui kendaraan bermotor lebih besar dibanding di Cagar Alam.Kata kunci: stomata, Mangifera indica Abstract. The study aims to determine the stomata of the leaves of mango (Mangifera indica) in areas with different environmental conditions. The research is descriptive analysis. Sampling was done through a random survey in Pananjung Pangandaran Nature Reserve and one of the roads in Pangandaran Sub District, Pangandaran District. The observed parameters are the density and stomatal damage. Moreover measured the leaf area, weight of the particles of dust off the leaves, as well as some physical environmental factors such as light intensity, temperature, and humidity. The results showed that the leaf stomatal density and damage to mango (Mangifera indica), which grows in the street that many passed the motor vehicle is greater than in the Nature Reserve.Keywords: stomata, Mangifera indica
