<![CDATA[Hydroponic cultivation has become an important agricultural innovation for addressing land limitations and improving resource efficiency; however, community interest in adopting this technology remains influenced by cognitive and psychological factors. This study examines the effects of technological knowledge and attitudes on community interest in hydroponic cultivation from a risk management perspective. A quantitative research design with a cross-sectional survey approach was employed involving 180 respondents. Data were collected through structured questionnaires and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS. The results indicate that technological knowledge has a positive and significant effect on community interest in hydroponic cultivation (β = 0.611; p < 0.001), while attitudes also demonstrate a positive and significant effect (β = 0.116; p = 0.037). Technological knowledge represents the stronger determinant, indicating that understanding technical aspects of hydroponic systems plays a crucial role in reducing uncertainty and increasing willingness to engage in agricultural innovation. The findings conclude that strengthening technological knowledge and developing positive attitudes are essential strategies for promoting community-based hydroponic cultivation. This study contributes to technology adoption literature and provides practical implications for designing training and empowerment programs to support sustainable agricultural development.]]>
