      Abstract
      Salah satu penghambat produktivitas perkebunan sawit adalah gulma. Beberapa gulma termasuk dalam kategori tumbuhan invasif. Penyebaran serta pertumbuhan dari tumbuhan invasif yang tidak terkendali dapat menyebabkan kerugian serta ancaman secara ekonomi maupun ekologi. Penelitian ini bertujuan menganalisis keragaman tumbuhan invasif di kawasan kebun kelapa sawit PT Perkebunan Nusantara II. Sampel tumbuhan diambil dengan membuat petak contoh pada 3 blok yang berbeda dan ditempatkan secara purposive sampling. Selanjutnya, dilakukan identifikasi spesies dan analisis data yang mencakup Indeks Nilai Penting (INP), indeks keanekaragaman, indeks kesamaan dan indeks kemerataan. Spesies tumbuhan invasif yang ditemukan sebanyak 20 dari 61 spesies gulma yang berasal dari 13 famili. Spesies invasif yang ditemukan memiliki habitus herba, semak dan perdu. Spesies invasif didominasi oleh tumbuhan dari famili Poaceae dan Asteraceae. Jenis Asystasia gangetica, Mitracarpus hirtus, Peperomia pellucida dan Phyllanthus urinaria ditemukan dalam tiga blok. Namun, berdasarkan nilai INP hanya tiga spesies yang dapat tergolong memiliki pengaruh pada komunitasnya yaitu Phyllanthus urinaria, Setaria plicata dan Peperomia pellucida.
       
      Several species of weeds which are categorized as invasive plants are one of the causes of inhibiting plantation productivity. The uncontrolled spread andgrowth of invasive plants can cause economic and ecological losses. This study aimed to analyze the diversity of invasive species in the palm oil plantation area of PT Perkebunan Nusantara II. Plant samples were taken by making sample plots in 3 different blocks and placed by purposive sampling. Furthermore, species identification and data analysis were carried out including the Important Value Index (IVI), diversity index, similarity index and evenness index. There are 20 invasive species from 61 weed species belonging to 13 families. The invasive species have a habitus of herbs, bushes and shrubs. Invasive species are dominated by species from the families Poaceae and Asteraceae. Asystasia gangetica, Mitracarpus hirtus, Peperomia pellucida and Phyllanthus urinaria species were found in all three blocks. However, based on the IVI value, only three species can be categoried affecting the community, namely Phyllanthus urinaria, Setaria plicata and Peperomia pellucida.
