The Climate Smart Agriculture program aims to educate farmers in preventing the negative impacts of climate change through the Climate Smart Agriculture Field School (SL-CSA). The success of Climate Smart Agriculture requires the level of application of SL-CSA materials and farmer participation. The study aims to analyze the level of application of SL-CSA materials and farmer participation in the Climate Smart Agriculture Field School in Ambulu District, Jember Regency. The study was conducted in Ambulu District which has the Talang and Pondok Waluh Irrigation Areas which are the requirements for the implementation of SL-CSA. Data collection methods were observation, documentation studies and interviews. The research respondents were farmers participating in the SL-CSA in Ambulu District. Data were analyzed using Scoring and Spearman Rank Correlation analysis. The results showed that the level of application of materials by SL-CSA farmers in Ambulu District was categorized as high. The level of application of materials by farmers can be seen from the materials provided in SL-CSA that have been applied by several farmers. Several farmers who did not apply were constrained by finances and farmer awareness. The level of farmer participation in SL-CSA in Ambulu District was categorized as high. The level of farmer participation in SL-CSA can be reviewed at the level of farmer attendance and activity in each SL-CSA activity. The frequency of attendance and farmer activity are significantly correlated and have a positive direction with the level of application of materials by farmers. Internal characteristics (age and education level) and external characteristics (land area, employment status, land ownership and productivity level) are not significantly correlated and have a negative direction.
