The West Sumatra provincial government from 2016 to 2018 implemented a new paddy field expansion programme. Currently, 73.33% of paddy fields are not managed by farmers. The paddy fields have been converted into plantations, buildings, and many are abandoned. The purpose of this study is to formulate strategies that can optimize the management of rice paddy farming in the location of new rice field expansion in the province of West Sumatra. This research uses mixed methods, combining quantitative methods with qualitative methods. The type of research used is survey research.

In addition, interview techniques were used in conjunction with direct observation activities at the research site. Secondary data were obtained through documentation techniques, which were analyzed using the content analysis method. Qualitative data were analyzed using descriptive interpretative techniques, while quantitative data were analyzed using multivariate analysis techniques in Structural Equation Modeling -Partial Least Square (SEM-PLS). The results of this study are that only 26.67% of the new rice fields are managed by farmers. Strategies that can be used to optimize rice wetland management in new wet rice-expansion areas include optimizing agricultural extension to empower farmers' institutions and competencies, improving irrigation infrastructure, and utilizing wet rice farming technology. The strategy can be an input for the government in formulating policies to optimize the management of paddy farming in the location of new rice field expansion.
