      Abstract
      Peningkatan produktivitas hutan alam dapat dilakukan dengan menerapkan teknik tanam rumpang. Tujuan dari teknik tanam rumpang adalah untuk merehabilitasi hutan alam terdegradasi dengan penanaman fast growing species lokal non Dipterocarpaceae yang berdaur pendek (5-8 tahun) di dalam areal rumpang. Penelitian ini bertujuan untuk mendapatkan informasi erosi tanah yang terjadi akibat tanam rumpang pada kondisi areal hutan alam, simpukan dan jalur tanam. Penelitian dilakukan pada bulan Mei 2021. Penelitian dilakukan pada dua kelas kelerengan yaitu kelas datar-landai dan kelas sedang. Hasil uji statistik menunjukkan tidak berbeda nyata antara besarnya erosi tanah pada kelas lereng datar-landai dan kelas lereng sedang. Hasil penelitian menunjukan besar erosi tanah yang terjadi secara berturut-turut dari yang terbesar ke terkecil adalah di areal hutan alam, di areal jalur tanam dan di areal jalur simpukan.
       
      Increasing the productivity of natural forests can be done by applying the gap planting technique. The purpose of the gap planting technique is to rehabilitate degraded natural forests by planting local intolerant fast-growing species with short cycles (5-8 years) in the gap area. This study aims to obtain information on soil erosion that occurs due to gap planting activities on the condition of natural forest areas, erosion barrier strips, and planting strips. The study was conducted in May 2021. The study was conducted on two slope classes, the flat to sloping class and the moderate class. The result of statistical tests showed that the magnitude of erosion on the flat to sloping class and moderate class was not significantly. The results showed that the amount of soil erosion that occurred successively from the largest to the smallest was the area of natural forest, planting area, and erosion barrier area.
