      Abstract
      Penambangan menimbulkan dampak negatif bagi lingkungan, seperti berkurangnya keanekaragaman hayati, terganggunya habitat satwa, pencemaran lingkungan, serta hilangnya area serapan karbon dan pemasok oksigen. Area yang terdampak dapat dipulihkan melalui rehabilitasi, sehingga diperlukan penilaian keberhasilan rehabilitasi. Penelitian ini bertujuan mengetahui keanekaragaman jenis tumbuhan, nilai serapan CO2, serta menganalisis keberhasilan rehabilitasi melalui keanekaragaman tumbuhan (H’), indeks kesamaan jenis tumbuhan (IS), tutupan tajuk, dan serapan CO2. Analisis data dilakukan dengan mengkaji komposisi tumbuhan, indeks keanekaragaman jenis tumbuhan, indeks kesamaan jenis tumbuhan, serapan CO2, forest canopy density, dan tingkat keberhasilan rehabilitasi. Hasil penelitian menunjukkan bahwa nilai H’ tertinggi terdapat pada rehabilitasi tahun 2001 dengan nilai 2,203. Secara umum, nilai H’ meningkat dari tahun termuda hingga tertua dan tergolong kategori sedang. Nilai serapan CO2 tertinggi terdapat pada rehabilitasi tahun 2009 dengan nilai 707,29 ton/ha. tingkat keberhasilan rehabilitasi tertinggi, yang paling mendekati hutan alam, adalah tahun 2001 dengan nilai 0,878 dan yang terendah adalah tahun 2017 dengan nilai 0,764.
       
      Mining has negative impacts on the environment, such as reduced biodiversity, disruption of animal habitats, environmental pollution, and loss of carbon sequestration and oxygen supply areas. Affected areas can be restored through rehabilitation, so it is necessary to assess the success of rehabilitation. This study aims to determine the diversity of plant species, the value of CO2 uptake, and analyze the success of rehabilitation through plant diversity (H'), plant species similarity index (IS), crown cover, and CO2 uptake. Data analysis was carried out by examining plant composition, plant species diversity index, plant species similarity index, CO2 uptake, forest canopy density, and rehabilitation success index. The results showed that the highest H' value was found in the 2001 rehabilitation with a value of 2,203. In general, the H' value increased from the youngest to the oldest year and was classified as moderate. The highest CO2 absorption value was found in the 2009 rehabilitation with a value of 707,29 tons/ha. The highest rehabilitation success index, which is closest to natural forest, was 2001 with a value of 0,878, while the lowest was 2017 with a value of 0,764.
