      Abstract
      Tumbuhan asing invasif merupakan tumbuhan yang bukan berasal dari suatu wilayah, namun spesies tumbuhan tersebut mampu bertahan hidup pada wilayah baru serta dapat mengancam spesies tumbuhan asli. Penelitian ini bertujuan mengetahui keanekaragaman spesies tumbuhan asing invasif dan sebarannya di Bumi Perkemahan dan Graha Wisata Pramuka (BUPERTA) Cibubur. Pengambilan data dilakukan dengan metode kuadrat dengan penempatan plot sengaja (purposive sampling). Plot utama berukuran 10 m x 10 m dibuat pada lokasi perkemahan 1, lokasi perkemahan 2, dan arboretum. Setiap plot utama dibuat 3 subplot contoh berukuran 2 m x 2 m. Data vegetasi dianalisis untuk mendapat indeks nilai penting (INP), indeks keanekaragaman Shannon-Wiener (H’), indeks kesamaan (IS), indeks dominansi (D), dan indeks kemerataan (E). Hasil analisis vegetasi menunjukan spesies tumbuhan asing invasif yang ditemukan pada lokasi penelitian terdapat 9 spesies yang termasuk ke dalam 8 famili. Spesies tumbuhan asing invasif yang mendominasi pada dua dari tiga lokasi penelitian, yaitu Asystasia gangetica, Mimosa pudica, dan Stachytarpheta indica.
       
      Invasive alien species is a plant that does not originate from a region. However, these plant species can survive in new areas and threaten native species. This research was conducted to determine the diversity and distribution of invasive alien plant species in Bumi Perkemahan dan Graha Wisata Pramuka (BUPERTA) Cibubur. Data collection was taken using the quadrat method with purposive sampling. The main plot measuring 10 m x 10 m was made in campsite 1, campsite 2, and arboretum. For each main plot, 3 sample plots measuring 1 m x 1 m were made. Vegetation data were analyzed to determine the Important Value Index (IVI), Shannon-Wiener diversity index (H'), similarity index (IS), dominance index (D), and evenness index (E). The vegetation analysis showed that 9 species and 8 families of invasive alien plant species were found at the research locations. Invasive alien plant species dominated in two of the three study locations, Asystasia gangetica, Mimosa pudica, and Stachytarpheta indica.
