Institutional visibility is key to achieving success and sustainable growth in today's digital era. Developing a responsive web profile increases visibility by providing optimal user experience across various devices and screen resolutions effectively. The prototyping method was the primary approach in developing this responsive web profile. It allows developers to create initial models that can be tested and evaluated before the full development of the web profile. The research explains the steps in developing a responsive web profile using prototyping. The results show that this method offers an efficient and practical approach to creating a responsive web profile, ensuring user satisfaction, and meeting the increasing expectations of users. Therefore, institutions should consider applying this prototyping method to strengthen their visibility through innovative, responsive web profiles. Responsive web profiles enable institutions to reach and engage their target audience through different devices, enhancing user engagement and providing consistent user experiences. The result shows that prototyping enhances institutional web profiles, improves user experience, and effectively increases visibility with high satisfaction, with an average of 83.2.

INTRODUCTION The internet has become integral to human life in today's digital era. More people are searching the internet for information about specific institutions such as schools, colleges, or companies [1]. In this context, responsive web profiles have become one of the media to promote these institutions [2]. However, many institutions still need to maximize their responsive web profiles' potential fully. This research aims to enhance institutional visibility by implementing the prototyping method [3], [4] in responsive web profiles. The prototyping method is essential because it can assist institutions in developing ideas and creating more efficient and effective designs before implementing them in responsive web profiles [5],[6]. As a result, institutions can create more engaging, informative, and user- friendly responsive web profiles. In education, responsive web profiles can serve as a medium to introduce institutions to prospective students and parents. By providing comprehensive and accurate information, institutions can expand their reach and enhance their reputation in the public eye. Moreover, responsive and user-friendly profiles can influence prospective students' perceptions of institutions and increase their interest in joining [7]. Several articles serve as relevant references in exploring the application of prototyping techniques in developing responsive web profiles for institutions. This study [8] discusses web development and design techniques that enhance user experience and institutional visibility. The use of the prototyping method in web design, which can improve the efficiency and effectiveness of developing web profiles, was explored in this paper [9]. Additionally, innovation challenges in user experience design with a new, relevant method, as the prototyping method can enhance institutional visibility
