      Abstract
      Hutan berperan penting dalam siklus karbon dunia karena mampu menyerap karbon dioksida (CO2) dari atmosfer melalui proses fotosintesis, kemudian menyimpan karbon tersebut dalam biomassa tanaman dan tanah. Salah satu penyimpan cadangan karbon di hutan adalah kayu mati. Pengukuran cadangan karbon kayu mati perlu memperhatikan metode inventarisasi yang optimal. Penelitian ini bertujuan untuk menduga kerapatan kayu mati tiap tingkat pelapukan, penentuan transek optimal, serta menduga besar biomassa tersimpan. Metode pengukuran yang dilakukan dengan metode Line Intersection Sampling dengan teknik pengambilan data dengan purposive sampling. Besar nilai kerapatan kayu mati pada berbagai tingkat pelapukan memiliki nilai yang berbeda yakni kelas lapuk, agak lapuk dan tidak lapuk masing-masing bernilai 0,223–0,603 g/????3. Penentuan transek optimal menghasilkan alternatif desain terbaik yakni desain D8 dengan panjang transek 30 meter kearah utara selatan, timur barat. Pendugaan Biomassa dan cadangan karbon kayu mati terbagi dalam dua strata hutan. Hutan terdegradasi memiliki nilai cadangan karbon yang lebih tinggi dibandingkan dengan hutan primer.
       
      Forests play an important role in the global carbon cycle because they are able to absorb carbon dioxide (CO2) from the atmosphere through photosynthesis, then store the carbon in plant biomass and soil. One of the carbon reserves in forests is dead wood. Measuring dead wood carbon reserves requires consideration of the optimal inventory method. This study aims to estimate the density of dead wood at each decay stage, determine the optimal transect, and estimate the amount of stored biomass. The measurement method used was the Line Intersection Sampling method with data collection using purposive sampling. The density values of dead wood at various decay levels varied, with decayed, slightly decayed, and undecayed classes having values of 0.223–0.603 g/m³. Determining the optimal transect resulted in the best design alternative, namely design D8 with a transect length of 30 metres in a north-south, east-west direction. The estimation of biomass and carbon reserves of dead wood was divided into two forest strata. Degraded forests had higher carbon reserves than primary forests.
