摘要：Integrated Cropping Calendar Information System (ICCIS) is an application used to convey innovative research results related to cropping patterns, varieties, fertilization, pest attacks, agricultural tools and machinery. This study aims to identify the influencing factors and communication models in the implementation of ICCIS in the North Sumatra region. Data analysis uses the Partial Least Squares Structural Equation Modelling (PLS-SEM) method. The result showed that the ICCIS Task Force Team (TGT Katam), characteristics of farmers, and characteristics of ICCIS have positive effects on the level of implementation of ICCIS by farmers, with variable significance values of 3.902, 3.851, and 8,296, respectively. In related to the level of application of ICCIS by farmers, the analysis results have a positive effect on the added value of the use of ICCIS with a significance value of 6.509. TGT Katam received ICCIS information from the central cropping calendar team and the technical implementation unit that oversees it. TGT Katam in the North Sumatra region delivered ICCIS information to farmers through socialization and demonstration plots. Interpersonal communication and the demonstration plot media encouraged farmers to implement ICCIS recommendations. Satisfy the local wisdom, compatibility, data accuracy, trialability, observability, and relative advantage are indicators that farmers can implement ICCIS.
