One of the potential germplasms that has not been properly recorded on Bangka Island is indigenous mushrooms, namely Pelawan red mushrooms (Heimioporus sp.) and their potential uses. Pelawan red mushroom is a type of edible fungus that is found in the root system of Pelawan trees (Tristaniopsis merguensis) as an ectomycorrhizal fungus. Research on Pelawan red mushrooms related to yield estimation has never been carried out. This research aimed to provide information related to yield estimation of Pelawan red mushrooms in Namang Village using a remote sensing approach. The observation was conducted 2 times in 2018 and 2021. Because this mushroom exists in symbiosis with Pelawan trees as the host tree, firstly, it is necessary to determine LULC to mark the Pelawan trees area, also vegetation index, including NDVI, EVI, and SAVI in the Pelawan trees area, so that the existing area can help in yield estimation of Pelawan red mushroom for each year. The yield estimation model approach used the correlation between Leaf Area Index (LAI) and the vegetation index. The evaluation demonstrated that Root Mean Squared Error (RMSE) values, which represent the difference between the actual yield and the estimated yield based on the LAI - NDVI and LAI - EVI correlations, were consistently 0.12 and 0.11 in both 2018 and 2021. This indicates the high accuracy and reliability of the estimated models, making them suitable for practical applications. Additionally, Mean Absolute Percentage Error (MAPE) values for the LAI - NDVI correlation were 28.25% in 2018 and 23.23% in 2021, while for the LAI - EVI correlation, the MAPE values were 27.33% in 2018 and 21.44% in 2021. These values further reinforce the notion that the estimation models fall within the range of reasonable estimation, affirming their validity and effectiveness.
