Analisis Spasial Model Pendugaan Karbon Menggunakan Unnamed Aerial Vehicle (UAV) Di Mangrove Lubuk Kertang

Abstract

Mangrove forest is a deep forest ecosystemigenerallyilocated at the mouth of the river tidal areailow tide and seaside,The most abundant and main carbon stocks in mangrove forests are found to come from measurements and results from the wet tropics. This study aims to obtain a carbon estimation model using the Lubuk Kertang mangrove UAV, the data collection method was carried out by purposive sampling while still paying attention to the representativeness and limitations of the data and age class as many as 79 observation plots measuring carbon content using allometric equations. Making VARI, GLI, VIgreen and canopy cover spatial models as variablesifree and amount of carbon as the dependent variable, the carbon potential estimation model was chosen based on VARI, GLI, Vigreen and canopy cover. The results showed that the linear regression model with canopy cover had the highest equation value y = 20.023x + 30.241 , R2 = 34.9% with RMSE value = 5.11, and had uniformity between models with an average carbon measurement in the field of 39.459 tonnes/ha .
