      Abstract
      Keberagaman struktur tegakan rumpang di areal bekas tebangan memegang peranan penting dalam menjaga stabilitas cadangan karbon. Penelitian ini menganalisis komposisi jenis dan potensi karbon pada 18 plot rumpang dengan variasi kelerengan dan luas bukaan. Inventarisasi lapang mencatat 711 individu dari 42 jenis yang membentuk struktur kurva J-terbalik dengan dominasi jenis Shorea. Kerapatan rata-rata 652,08 individu/ha dan bidang dasar 18,89 m²/ha mengindikasikan tegakan berada pada fase pertumbuhan muda dengan akumulasi biomassa belum optimal. Cadangan karbon tegakan dipengaruhi secara nyata oleh faktor kelerengan dibandingkan ukuran rumpang. Stok tertinggi ditemukan pada topografi berbukit akibat keberadaan pohon sisa (residual stand) yang terhindar dari pemanenan. Temuan ini mengindikasikan peran topografi berbukit sebagai perlindungan alami bagi pohon induk. Rata-rata total cadangan karbon mencapai 263,09 (SD = 85,10) ton C/ha, menegaskan tingginya kapasitas penyimpanan karbon pada rumpang dalam pemulihan ekosistem hutan.
       
      The diversity of gap stand structures in logged-over areas plays a crucial role in maintaining carbon stock stability. This study analyzes species composition and carbon potential in 18 gap plots with variations in slope and gap size. Field inventory recorded 711 individuals from 42 species forming an inverted J-curve structure dominated by Shorea species. An average density of 652.08 individuals/ha and a basal area of 18.89 m²/ha indicate that the stand is in a young growth phase with suboptimal biomass accumulation. Stand carbon stocks were significantly influenced by the slope factor rather than the gap size. The highest stock was found in hilly topography due to the presence of residual trees that escaped harvesting. These findings indicate the role of hilly topography as natural protection for mother trees. The average total carbon stock reached 263.09 (SD = 85.10) tons C/ha, highlighting the high carbon storage capacity of gaps in forest ecosystem recovery.
