In the global agricultural sector, corn-soybean intercropping offers significant long-term benefits for increased productivity, improved agroecology, and land management. While the impact of intercropping on corn and soybean yields has been studied extensively, information on their sustainability is limited. This study aims to analyse the status and sustainability determinants of the intercropping model on smallholder oil palm land through multidimensional analysis which includes economic, social, cultural, environmental, technological and institutional dimensions. Utilising a multi-dimensional scaling method with RAPFISH’s modified software, called Rapid Appraisal for Palm Oil. The analysis results show that the sustainability index for oil palm plantations using the corn-soybean intercropping model has a good status in the economic dimension, with price-sensitive production attributes for smallholders. The value of the sustainability index in the socio-cultural dimension of good status with sensitive attributes of community access to replanting requirements. The continuous index value in the environmental dimension of the status is very good with the attribute of sensitive pest disturbance. The value of the sustainable index in the technology dimension is in good status with sensitive attributes of post-harvest handling. The value of the sustainable index in the institutional dimension is in good status with sensitive attributes of smallholder’s group access to banking.
