The high risk of fatalities from maritime accidents in West Kalimantan waters due to extreme weather conditions requires a reliable meteorological information dissemination system for coastal communities. The BMKG Maritime Meteorology Station Pontianak launched the Maritime Info Portal as a digital safety platform, but its usability for non-expert users has not yet been formally evaluated. This study aims to evaluate the usability of the portal based on the ISO 9126 standard, focusing on four characteristics: Understandability, Operability, Learnability, and Attractiveness, using the USE Questionnaire as the measurement instrument. This study employed a descriptive quantitative method with purposive sampling involving 30 valid respondents consisting of traditional fishermen, IT academics, and general users. Statistical testing using IBM SPSS showed that all 13 questionnaire items met the validity criteria, while the instrument demonstrated high internal consistency with a Cronbach's Alpha value of 0.924. The results showed that all four usability characteristics were rated Good, with Attractiveness obtaining the highest score at 80.44%, followed by Operability at 76.22%, Learnability at 75.78%, and Understandability at 70.00%. Field observations also indicated that some traditional fishermen experienced difficulties in interpreting formal meteorological terms, particularly wind speed units such as knots. Based on these findings, practical recommendations include the use of localized terminology for fishermen, automated unit conversion, and mobile web optimization for low-bandwidth coastal areas.
