The increase in annual demand for sugar products in Indonesia is facing challenges, particularly in terms of sugarcane supply, the raw material for the sugar agro-industry. Sustainability assessment has been widely conducted using various approaches; however, it has not accounted uncertainty of future conditions in the analyses. This study aims to develop a model for assessing the sustainability of sugarcane supply using a Multiaspect Sustainability Analysis (MSA) approach. It involves analyzing the situation and conditions of raw material supply, determining the key aspects and factors for the sustainability assessment model, and implementing the model to assess the sustainability of sugarcane supply. The model included three primary aspects (economic, social, and environmental) comprising 22 factors. Two- year data from a West Javan sugar mill, along with potential future conditions, were used for the analysis. The findings show that the sugarcane supply sustainability has improved from being "Moderate sustainable" to "Sustainable". The economic aspect is suggested as the priority for improvement, with five sensitive leverage factors. This study effectively integrated both current and possible future conditions into the analysis. The simulation resulted in Scenario 2 showing the best improvement. These findings serve as a basis for developing strategic plans to improve the sustainability.
