      Abstract
      Durian (Durio zibethinus) merupakan salah satu komoditas dengan produksi yang terus meningkat setiap tahunnya, menyebabkan adanya peralihan fungsi lahan hutan, dan dapat menurunkan stok karbon wilayah tersebut. Penelitian ini bertujuan menjelaskan kondisi stok karbon daerah perkebunan durian, menganalisis kondisi vegetasi daerah perkebunan durian melalui indeks NDVI, serta menentukan kesesuaian model estimasi stok karbon dari NDVI yang telah ada sebelumnya. Penelitian dilakukan selama bulan Januari – Mei 2024. Analisis dilakukan dengan beberapa tahapan, yaitu analisis NDVI dengan data satelit Landsat 8 (band 4 dan band 5), evaluasi kesesuaian 9 model estimasi stok karbon yang ada (Lombok Barat, Banyumas, dan Wonosobo) melalui nilai RMSE dan korelasi pearson, serta penerapan model terbaik untuk estimasi stok karbon 2017 – 2023. Hasil analisis menunjukkan bahwa data lapangan stok karbon di perkebunan durian cenderung mengalami peningkatan seiring meningkatnya umur pohon. NDVI di wilayah perkebunan durian bervariasi pada rentang 0,2911 – 0,3929. Evaluasi model stok karbon menghasilkan galat yang cukup besar dengan korelasi pearson yang lemah disebabkan oleh komoditas yang berbeda. Penerapan model terbaik, C = 422.33(NDVI)^3,0547 menunjukkan adanya kecenderungan peningkatan stok karbon dari tahun 2017 – 2023.
       
      The production of durian (Durio zibethinus) has been increasing annually, resulting in the conversion of forest land functions and a reduction in the carbon stock of the region. This research aims to elucidate the carbon stock status of durian plantations, analyze the vegetative condition of durian plantations through the NDVI index, and ascertain the suitability of existing carbon stock estimation models based on NDVI. The research was conducted over the period from January to May 2024. The analysis was conducted in several stages. Initially, NDVI analysis was performed using Landsat 8 satellite data (bands 4 and 5). Subsequently, the suitability of nine existing carbon stock estimation models was evaluated (West Lombok, Banyumas, and Wonosobo) through RMSE and Pearson correlation values. Finally, the most suitable model was applied for carbon stock estimation from 2017 to 2023. The results of the analysis indicate that the field data of carbon stocks in durian plantations tend to increase with increasing tree age. The NDVI in the durian plantation area exhibited a range of 0.2911 to 0.3929. The evaluation of the carbon stock model yielded considerable errors with a weak Pearson correlation due to the differing commodities. The application of the optimal model, C = 422.33(NDVI)^3.0547, demonstrated an increasing trend in carbon stocks from 2017 to 2023.
