      Abstract
      Pemanasan global berdampak pada timbulnya gas rumah kaca yang berpengaruh terhadap kehidupan manusia. Pengukuran biomassa perlu dilakukan untuk mengetahui besaran potensi cadangan karbon. Penelitian ini bertujuan menentukan model terbaik dalam menduga karbon berdasarkan variabel nilai leaf area index (LAI) pada areal Perizinan Berusaha Pemanfaatan Hutan (PBPH) PT RAPP. Nilai LAI diperoleh menggunakan metode hemispherical photography. Analisis regresi dilakukan untuk menganalisis hubungan kandungan karbon permukaan atas tanah dengan nilai LAI. Model regresi yang digunakan berupa model regresi linear dan non-linear dengan variabel independen berupa nilai LAI dan variabel dependen berupa karbon permukaan atas tanah. Model terbaik dipilih berdasarkan parameter uji keberartian model, yaitu nilai R^2 dan nilai SE. Hasil penelitian menunjukkan bahwa model terbaik yaitu model C=1,48+10,75×ln?(LAI) dengan nilai R^2 sebesar 30,18% dan nilai SE sebesar 1,71.
       
      Global warming impacts the emergence of greenhouse gases that affect human life. Biomass measurements need to be conducted to determine the amount of potential carbon stocks. This study aims to determine the best model for estimating carbon based on the leaf area index (LAI) values variable in the PBPH area of PT RAPP. LAI values are obtained using the hemispherical photography method. Regression analysis was conducted to analyze the relationship between aboveground carbon with LAI values. The regression models used are linear and non-linear regression models with LAI values as the independent variable and aboveground carbon as the dependent variable. The best model is selected based on the model significance test parameters, namely R^2 value and SE value. The result shows that the best model is C=1.48+10.75×ln?(LAI) with R^2 value of 30.18% and SE value of 1.71.
