      Abstract
      Hutan Pendidikan Gunung Walat (HPGW) sebagai hutan tanaman memiliki kontribusi serasah dan humus yang cukup tinggi terhadap potensi biomassa, karbon dan emisi CO2. Hal itu dikarenakan serasah dan humus di HPGW sangat melimpah. Penelitian ini bertujuan untuk menduga potensi biomassa, karbon dan menduga emisi CO2 di HPGW. Pengambilan data di lapangan dilakukan secara destruktif dengan metode simple random sampling yaitu peletakan plot contoh secara acak agar menggambarkan dan mewakili tiap tegakan yang ada di HPGW. Plot contoh berbentuk persegi dengan ukuran (2 x 2) m dengan total plot sebanyak 83 plot dengan total sampel yang diambil sebanyak 166 sampel. Pengambilan data di laboratorium dengan mengoven serasah dan humus pada suhu 105 °C selama 24 jam. Hasil dugaan biomassa serasah dan humus secara berturut-turut sebesar 3,91 ton/ha dan 0,923 ton/ha. Pendugaan karbon serasah dan humus secara berturut-turut sebesar 1,839 ton/ha dan 0,434 ton/ha. Emisi CO2 dari proses dekomposisi serasah dan humus secara berturut-turut diperkirakan sebesar 6,74 ton CO2/ha dan 1,59 ton CO2/ha.
       
      Gunung Walat Educational Forest (HPGW) as a plantation forest has a high litter and humus contribution to the potential for biomass, carbon and CO2 emissions. because the litter and humus in HPGW is very abundant. The purpose of this research is to estimate the potential of biomass, carbon and to estimate CO2 emissions in HPGW. Data collection in the field was carried out destructively with the simple random sampling method, namely the placement of sample plots at random in order to describe and represent each stand in the HPGW. The sample plots are square with the size (2 x 2) m with a total plot of 83 plots with a total of 166 samples taken. Data were collected in the laboratory by roasting the litter and humus at a temperature of 105 °C for 24 hours. The estimated results of litter and humus biomass were 3.91 tons/ha and 0.923 tons/ha, respectively. Estimation of litter and humus carbon was 1.839 tons/ha and 0.434 tons/ha, respectively. CO2 emissions from the decomposition of litter and humus were estimated at 6.74 tons CO2/ha and 1.59 tons CO2/ha, respectively.
