Hutan rakyat memegang peranan yang tak kalah penting dalam aspek ekologis jika dibandingkan hutan jenis lainnya, salah satunya sebagai penyimpan karbon yang membantu dalam mitigasi perubahan iklim global. Keberadaan hutan rakyat yang termasuk bagian dari wilayah perkotaan cukup jarang ditemukan, sehingga penelitian ini perlu dilakukan mengingat lokasinya yang cukup istimewa. Penelitian ini bertujuan untuk mengestimasi simpanan karbon yang terdapat pada hutan rakyat di kawasan perkotaan Kota Bandar Lampung, Provinsi Lampung. Metode yang digunakan pada penelitian ini yaitu metode destruktif dan non-destruktif. Pengukuran simpanan karbon dilakukan pada tiga carbon pool yakni biomasa di atas tanah; nekromasa; serasah dan tumbuhan bawah. Pengukuran tersebut dilakukan dengan melakukan inventarisasi vegetasi pada 15 klaster plot yang berlokasi di hutan rakyat Kelurahan Pinang Jaya tersebut. Hasil penelitian menunjukkan bahwa rerata simpanan karbon berkisar 54,59 tC/ha dengan interval nilai 48,93 tC/ha sampai 60,26 tC/ha. Biomasa di atas tanah memegang persentase terbesar sebagai penyumbang simpanan karbon yaitu sebesar 95,71%, diikuti dengan nekromasa 4,23%, serasah dan tumbuhan bawah 0,05%.

Global climate change and forest health are currently two things that need to be studied more deeply. Forests store carbon, including in the community forests. A healthy forest can perform its function properly including as a carbon sinker as well as a carbon repository. This study aims to analyze carbon storage as an indicator of forest health in community forests in Pinang Jaya Village. The data were collected by using cluster plots based on the method of Forest Health Monitoring (FHM), totaling 15 units. The measurement method used is destructive and non-destructive. The result showed that the average carbon storage in community forests in Pinang Jaya Village is 54.59 tC/ha. The largest contribution to carbon storage was AGB with a percentage of 95.71%, followed by necromass at 4.23%, and 0.05% litter and understorey. Based on the results of the analysis, carbon storage can perform as an indicator of forest health in the community forests of Pinang Jaya Village with the bad, medium, and good categories. The plot clusters are in the Good category (70.61 tC/ha - 83.66 tC/ha), namely cluster plots 13, Moderate categories (57.55 tC/ha - 70.60 tC/ha), namely cluster plots 4 and 14, and the Bad category (44.49 tC/ha - 57.54 tC/ha), namely cluster plots 1-3, 5-12.15, with the percentage of each category of 7%, 13%, and 80%.
