Abstract

Salah satu peran penting ekosistem lamun yaitu sebagai penyerap karbon yang berasal dari atmosfer. Pulau Bintan merupakan salah satu pulau dengan hamparan padang lamun yang cukup luas. Penelitian ini bertujuan untuk mengestimasi kandungan karbon pada padang lamun yang berasal dari seluruh jenis lamun dan sedimen yang berada di perairan Berakit dan Dompak Pulau Bintan. Penentuan potensi cadangan karbon dilakukan dengan melihat estimasi cadangan karbon di dalam sedimen dan biomassa lamun meliputi bagian atas (daun dan pelepah daun) dan bagian bawah lamun (rhizome dan akar). Pengukuran stok karbon pada sedimen lamun dilakukan dengan menggunakan metode pengabuan kering atau Loss on Ignation (LOI) dan kandungan karbon pada biomassa lamun diukur menggunakan metode konversi dengan konstanta. Hasil penelitian menunjukkan pada stasiun Berakit estimasi total cadangan karbon sedimen sebesar 91 Mg Corg ha-1 dan 10,58 Mg C/m2 untuk estimasi kandungan karbon lamun, sedangkan stasiun Dompak nilai estimasi total cadangan karbon pada sedimen berkisar103,80 Mg Corg ha-1 dan 3,34 Mg C/m2 untuk estimasi kandungan karbon bagian lamun. Kandungan karbon pada substrat dipengaruhi oleh komposisi sedimen dan kandungan karbon pada lamun dipengaruhi oleh kerapatan lamun.

Abstract

Pengudang Village, Bintan Regency, Riau Islands, is a coastal area that hosts seagrass ecosystems with high biodiversity. However, this area is increasingly experiencing degradation pressures due to climate change and anthropogenic activities. The limited public knowledge regarding the condition of seagrass ecosystems has become a major obstacle to community-based conservation efforts in the region. This community service activity aimed to disseminate information on seagrass density mapping results using the Object-Based Image Analysis (OBIA) technology to the coastal community of Pengudang. The mapping was conducted at 59 survey points distributed across the shallow waters of Pengudang Village in October 2025. The results identified seven seagrass species with a total coverage area of 344.26 hectares, of which approximately 92% fell into the high-density category. The dissemination of the mapping results was carried out in December 2025 using an interactive outreach method supported by visual media and infographics, and was evaluated through questionnaires distributed to 10 respondents. The evaluation results showed that all assessment indicators were within a score range of 3.7–4.0, categorized as Very Good, with no respondents expressing disagreement regarding either the material or the implementation of the activity. This activity demonstrates that a dissemination approach based on modern mapping technology, delivered through participatory and contextual methods, is effective in improving public understanding, awareness, and conservation motivation among coastal communities toward seagrass ecosystems.
