The research was conducted in Bangka Belitung Province which is the center of national pepper production. The farmer sample included 259 respondents taken using the multistage random sampling method. Survey, observation, interview, and questionnaire methods were applied to collect data. The data was examined with Covariance-based Based Structural Equation Modeling (CB-SEM). The research model is built based on an exogenous construct consisting of the role of extension workers, personal factors, and environmental factors, while the endogenous construct is an increase in the implementation of Good Agricultural Practices - Muntok White Pepper. The results of the study show that the strategy model for improving the implementation of Good Agricultural Practices - Muntok White Pepper (GAP-MWP) by increasing the capacity of the role of agricultural extension workers includes education, as well as increasing personal factors including motivation and perception. Increasing the capacity of extension workers technically includes land selection and cultivation as well as integrated cultivation management, in addition to the importance of increasing motivation and changing negative perceptions of farmers.
