      Abstract
      Sistem silvikultur Tanam Rumpang Tebang Rumpang (TRTR) diharapkan menjadi salah satu sistem silvikultur untuk merehabilitasi hutan alam terdegradasi. Penelitian ini bertujuan mengetahui pertumbuhan jabon putih yang ditanam dalam rumpang serta mengetahui pengaruh kemiringan lapangan terhadap pertumbuhan jabon putih. Metode penelitian menggunakan cara sensus dan pengukuran diameter dan tinggi total pohon jabon putih yang terdapat dalam 16 buah rumpang dengan luas masing-masing rumpang 2000 m^2. Hasil penelitian menunjukkan bahwa ukuran diameter berumur dua tahun adalah 7,42 cm dan tinggi total pohon rata-rata mencapai 651,11 cm. Uji statistik menunjukkan terdapat perbedaan nyata pengaruh kelerengan dengan jabon putih. Jabon putih tumbuh lebih baik pada kelas lereng curam dibandingkan dengan kelas lereng datar -landai dan sedang.
       
      The Gap Planting and Gap Cutting silvicultural system (TRTR) is expected to be one of the silvicultural systems to rehabilitate degraded natural forests. This study aims to determine the growth of white jabon planted in gaps and to determine the effect of slope on the growth of white jabon. The research method used the census and measured the diameter and total height of the white jabon trees contained in 16 gap plots of stump with an area of 2000 m^2 each. The results showed that the diameter at two years old was 7,42 cm and the average total height of the trees was 651,11 cm. Statistical tests showed that there were significant differences in the effect of slopes on white jabon growth. White Jabon grows better on steep slopes compared to flat-sloping and moderate slopes.
