Data collection in smallholder sugarcane plantations is still very sensitive to the subjectivity of informants and data collectors. In the meantime, the problem with data collection on sugarcane plantation companies is a low response rate. This situation can reduce the precision of the estimates that are produced. Consequently, the goal of this research is to recognize sugarcane fields using the machine learning models on Sentinel-2A satellite imagery in Kediri Area that covering Kediri Regency and Kediri Municipality, East Java. Along with developing machine learning algorithms, this research will evaluate how well LightGBM performs when compared to other algorithms, including CART, SVM, Random Forest, and XGBoost. Each model employed hyperparameter tuning with random search and stratified 10-fold cross validation to avoid overfitting. The process of labelling satellite imagery using images from Google Street View, then predictor variables used are NDVI, NDWI, NDBI, EVI, and elevation. The most accurate classification model obtained was LightGBM, with a 98% accuracy and a cohen’s kappa of 97.7% . The estimated area of sugarcane plantations in the Kediri Regency and Kediri Municipality in September 2022 is 18,897.6 ha and 571.87 ha.  \nKeywords: remote sensing, CART, SVM RBF kernel, SVM polynomial kernel, Random Forest, XGBoost, LightGBM  \n1 INTRODUCTION  \nSugarcane (Saccharum officinarum) is a member of the Gramineae family, which includes grasses. The sugar and monosodium glutamate (MSG) industries utilize the water extracted from sugarcane stalks as a raw ingredient. (Syathori & Verona, 2020) . Thousands of factory workers and sugarcane farmers depend on the sugarcane and MSG industries for a living. Furthermore, sugar has become a necessity for most Indonesians (Sulaiman et al. , 2018) .  \nIndonesia's annual sugar  \nconsumption continues to rise (BPS, 2022) . However, the sugarcane plantations area did not rise considerably; in fact, it decreased because of land conversion. As part ofits attempts to establish national food security, the Indonesian government is  \nattempting to attain self-sufficiency in sugar production (Sulaiman et al. , 2018) .  \nAccurate and up to date data on sugarcane plantations is required to progress sugarcane plantations in Indonesia. Statistical Agency (BPS) and the Directorate General of Plantations are the two primary data sources for sugarcane plantations in Indonesia. BPS obtained data related to sugarcane plantation companies using Computer Assisted Web Interviewing (CAWI)-based self-enumeration and by interviewing companies that had not filled out the form. (BPS, 2022) .  \nMeanwhile, the Directorate General of Plantations collects statistics on smallholder plantations through field officers' estimations. Officers will collect data on planting methods, population density per hectare, land area (distinct from planting area), and other factors.  \nThe sources of information included planters, farmer groups, village officials, and others. Officers will estimate the area based on this data in accordance with the Guidelines for Implementing Plantation Commodity Data Management (PDKP) (Kementrian Pertanian, 2013) .  \nHowever, until recently, data gathering on smallholder plantations was very sensitive to informant and data collector subjectivity (Ruslan & Prasetyo, 2021) . The guidelines for creating predictions that are not up to date can provide estimates that are not in agreement with the present circumstance. Moreover, the problem with data gathering on sugarcane plantation companies is a l","cbCaitbA5z8jLggS","https://ap.wps.com/l/cbCaitbA5z8jLggS","pdf",1736998,1,14,"English","en",105,"# Abstract\n# Introduction\n## Data sensitivity and response-rate limitations\n## Need for up-to-date plantation data\n## Remote sensing and machine learning background\n# Methods (from abstract)\n## Machine learning models and comparison\n## Feature labeling and predictor variables\n## Hyperparameter tuning and cross validation","[{\"question\":\"What is the best-performing model and the estimated sugarcane area?\",\"answer\":\"LightGBM is the most accurate, reaching 98% accuracy with Cohen’s kappa 97.7%.
