Abstract
Teluk Kendari merupakan bagian wilayah Kota Kendari yang sangat strategis sebagai pusat kegiatan masyarakat. Berbagai macam aktivitas pembangunan di Teluk Kendari menyebabkan hutan mangrove sangat rentan terdegradasi. Hutan mangrove yang terdegradasi akan berdampak pada penurunan stok karbon mangrove secara signifikan. Mangrove sangat berperan dalam mitigasi perubahan iklim, karena memiliki kemampuan penyerapan karbon yang tinggimelalui proses fotosintesis dan diubah menjadi bahan organik dan tersimpan di dalam sedimen. Penginderaan jauh dan pemodelan spasial dapat digunakan untuk memperkirakan degradasi stok karbon mangrove. Pemodelan spasial InVEST(Integrated Valuation Of Ecosystem Services And Tradeoffs)dapat digunakan untuk memprediksi stok karbon mangrove yang terdegradasi pada waktu tertentu akibat perubahan penggunaan lahan. Tujuan penelitian ini adalah untuk mengkaji degradasi stok karbon total mangrove berdasarkan data penginderaan jauh dan model spasial InVEST tahun 1982, 2000, 2019 di Teluk Kendari serta mengkaji prediksi stok karbon total mangrove berdasarkan model spasial InVEST tahun 2040 di Teluk Kendari. Data yang digunakan untuk melihat perubahanstok karbon total mangrove adalah data citra penginderaan jauh satelit Landsat danreferensi nilai stok karbon total mangrove. Hasil penelitian menunjukkan bahwa stok karbon total mangrove di Teluk Kendari mengalami degradasi sebesar 2.964.830 tonCO2 dari tahun 1982 sebesar 4.454.922 tonCO2menjadi 1.490.091 tonCO2pada tahun 2019. Stok karbon total mangrove di Teluk Kendari dari tahun2019 di prediksi akan mengalami peningkatan sebesar 27.302tonCO2 menjadi 1.517.393 tonCO2 di tahun 2040 dengan asumsi luas area mangrove dari tahun 2019 hingga 2040 tetap. Kata Kunci : Karbon, Mangrove, Teluk Kendari, InVEST, Degradasi, Prediksi Kendari Bay is part of the Kendari City area which is very strategic as a center for community activities. Various kinds of development activities in Kendari Bay make mangrove forests very vulnerable to degradation. Degraded mangrove forests will have an impact on reducing mangrove carbon stocks significantly. Mangroves play a very important role in mitigating climate change, because they have the ability to absorb high carbon through the process of photosynthesis and are converted into organic matter and stored in sediments. Remote sensing and spatial modeling can be used to estimate the degradation of mangrove carbon stocks. InVEST (Integrated Valuation Of Ecosystem Services And Tradeoffs) spatial modeling can be used to predict mangrove carbon stocks that are degraded at a certain time due to land use changes. The purpose of this study was to assess the degradation of total mangrove carbon stock based on remote sensing data and InVEST spatial models at 1982, 2000, 2019 in Kendari Bay and to assess the prediction of total mangrove carbon stock based on InVEST spatial model at 2040 in Kendari Bay. The data used to see the change in total mangrove carbon stock are remote sensing imagery data from the Landsat satellite and reference to the value of total mangrove carbon stock. The results showed that the total carbon stock of mangroves in Kendari Bay was degraded by 2,964,830 tonnes of CO2 from 1982 of 4,454,922 tonnes of CO2 to 1,490,091 tonnes of CO2 in 2019. The total carbon stock of mangroves in Kendari Bay from 2019 is predicted to increase. amounting to 27,302 tonnes of CO2 to 1,517,393 tonnes of CO2 in 2040, assuming the area of mangrove from 2019 to 2040 ispermanent.
