      Abstract
      Teknik pertambangan terbuka merupakan metode penambangan dengan cara mengupas lapisan tanah. Penelitian ini bertujuan menganalisis karakteristik vegetasi dan kimia tanah pada area revegetasi di lahan reklamasi pascatambang bauksit, serta membandingkan karakteristik vegetasi dan kimia tanah pada lahan revegetasi dengan ekosistem referensi (area zona penyangga) di sekitar area lahan pascatambang bauksit. Penelitian ini dilakukan dengan membuat plot berukuran 100 m x 20 m dengan metode jalur berpetak dengan menetapkan lokasi penelitian secara purposive sampling, sedangkan pengambilan sampel tanah untuk analisis sifat kimia tanah dilakukan dengan mengambil sampel tanah di dalam sub-plot sebanyak 5 titik. Karakteristik vegetasi pada area zona penyangga memiliki jenis tanaman yang lebih beragam dibandingkan area revegetasi umur 5 tahun. Hal tersebut dikarenakan pada area revegetasi umur 5 tahun hanya ditanami 4 jenis tanaman saja. Karakteristik sifat kimia tanah pada area revegetasi umur 5 tahun cenderung lebih rendah dibandingkan dengan area zona penyangga. Hal ini disebabkan pada kegiatan penambangan bauksit dilakukan pengupasan lapisan tanah atas sampai ke dalam tanah yang mengandung bauksit.
       
      Open pit mining is a mining method that involves stripping layers of soil. This study aims to analyze the characteristics of vegetation and soil chemistry in the revegetation area of post-bauxite mining reclamation land, as well as to compare the vegetation and soil chemistry characteristics of the revegetation area with the reference ecosystem (buffer zone area) around the post-bauxite mining land. The research was conducted by creating plots measuring 100 m x 20 m using a quadrat transect method, with the research locations selected through purposive sampling. Soil samples for chemical analysis were taken from five points within the sub-plots. The vegetation characteristics in the buffer zone area had a more diverse plant species compared to the 5-year-old revegetation area. This is because the 5-year-old revegetation area was only planted with four types of plants. The soil chemistry characteristics in the 5-year-old revegetation area tended to be lower compared to the buffer zone area. This is because during bauxite mining activities, the topsoil layer was stripped down to the soil containing bauxite.
