Pemanasan global telah menyebabkan terjadinya perubahan iklim yang ekstrim. Pembangunan hutan rakyat merupakan salah satu contoh nyata dari mitigasi perubahan iklim. Dalam hal ini hutan rakyat mempunyai peran penting sebagai penyerap karbon dioksida (CO2) melalui proses fotosintesis. Desa Nampeldento merupakan salah satu desa di Kecamatan Salaman, Kabupaten Magelang yang menerapkan praktik hutan rakyat dengan sistem agroforestri kopi. Informasi terkait potensi hutan rakyat sebagai penyerap karbon belum pernah dilaporkan secara detail. Oleh karena itu, penelitian ini dilakukan dengan tujuan untuk mengetahui potensi biomassa, simpanan karbon, serapan CO2, dan nilai ekonomi serapan CO2 pada tegakan penyusun hutan rakyat. Dalam penelitiani ini, pengukuran biomassa dilakukan menggunakan metode non-destructive sampling. Selanjutnya, pendugaan biomassa dilakukan dengan persamaan allometrik berdasarkan jenis pohon. Pendugaan simpanan karbon dihitung menggunakan asumsi bahwa 47% biomassa pohon tersusun dari karbon dan untuk serapan CO2 diperoleh dari konversi dengan konstanta 3,67. Serta taksiran ekonomi serapan CO2 dilakukan menggunakan metode benefit transfer dengan mengalikan nilai serapan CO2 dengan harga jual karbon. Hasil penelitian ini menunjukkan bahwa potensi biomassa, simpanan karbon, dan serapan serapan CO2 untuk agroforestri kopi di hutan rakyat Desa Nampeldento, Kecamatan Salaman, Kabupaten Magelang berturut-turut sebesar 1.002,77 ton/ha; 471,3 ton/ha; 1.729,68 ton/ha. Nilai ekonomi serapan CO2 agroforestri kopi hutan rakyat Desa Nampeldento dengan luasan 20 ha sebesar 69.332,92 USD atau setara dengan Rp 1.072.833.319,39. Dengan besaran nilai ekonomi tersebut kiranya perlu dipertimbangkan bahwa agroforestri kopi hutan rakyat Desa Nampeldento berpeluang diajukan dalam skema perdagangan karbon dunia.

Global warming has caused extreme climate change. Community forest development is one clear example of climate change mitigation. In this case, community forests have an important role as carbon dioxide (CO2) absorbers through the process of photosynthesis. Nampeldento Village is one of the villages in Salaman District, Magelang Regency that implements community forest practices with a coffee agroforestry system. Information on the potential of hutan rakyat as a carbon sink has never been reported in detail. Therefore, this research was conducted with the aim of determining the potential of biomass, carbon storage, CO2 sequestration, and the economic value of CO2 absorption in stands that made up community forests. In this research, biomass measurements were carried out using nondestructive sampling methods. Furthermore, estimation of biomass was carried out with allometric equations based on tree species. The estimation of carbon storage was calculated using the assumption that 47% of tree biomass was composed of carbon and for CO2 uptake obtained from conversion with a constant of 3.67. The economic estimation of CO2 absorption was carried out using the benefit transfer method by multiplying the value of CO2 absorption by the selling price of carbon. The results of this research showed that the potential of biomass, carbon storage, and CO2 absorption for coffee agroforestry in the community forest of Nampeldento Village, Salaman District, Magelang Regency was respectively 1.002,77 tons / ha; 471,3 tons/ha; 1.729,68 tons/ha. The economic value of CO2 absorption of coffee agroforestry in Nampeldento Village with an area of 20 ha was 69.332,92 USD or equivalent to Rp 1.072.833.319,39. With this amount of economic value, it was necessary to consider that the coffee agroforestry of the Nampeldento Village community forest had the opportunity to be proposed in the world carbon trading scheme.
