Abstract


Penelitian bertujuan untuk mengetahui jenis, populasi, frequensi, dan dominansi tanaman lidah buaya telah dilaksanakan di D. I. Yogyakarta, mulai bulan Maret hingga September 2012. Penelitian menggunakan metode analisis vegetasi, survei lokasi, dan pengambilan sampel tanaman dari lokasi kalurahan, kecamatan dalam kabupaten di wilayah Provinsi D. I. Yogyakarta. Untuk mengetahui jenis tanaman menggunakan metode deskripsi dengan kunci identifikasi metode dichotomi.Variabel pengamatan meliputi jenis tanaman, frequensi, dan dominansi tanaman. Analisis sidik ragam jenjang nyata lima persen, untuk mengetahui beda nyata antarkabupaten atau kecamatan. Hasil penelitian menunjukkan bahwa di D. I. Yogyakarta  ditemukan tiga jenis tanaman, yaitu: Aloe ferox Mill, Aloe vera (chinensis) L. dan Aloe barbadensis. Populasi tertinggi, baik di kabupaten atau provinsi Aloe vera (chinensis) L., populasi terendah adalah Aloe barbedensis. Frequensi jenis Aloe vera L dan Aloe ferox mill sama, yaitu 100 persen, sedangkan Aloe barbadensis paling rendah, yaitu 80 persen. Dominansi tertinggi dari jenis Aloe vera L.
