Abstract Telkom University is one of the educational institutions that implement asynchronous learning through its Learning Management System (LMS). Based on preliminary research conducted with 37 respondents, just 13. 5% of the participants LMS using a smartphone, because responsiveness The Discussion Forum is a frequently used feature with high student interaction. However, this feature has several shortcomings, such as the lack of responsiveness in the mobile web interface and the limited interaction between users and professors. This research will employ the Design Thinking methodology and adopt the Felder Silverman Learning Style (FSLS). The evaluation of the prototype design resulted in a System Usability Scale (SUS) testing score of 72. 22 for the LMS Celoe website and 85. 65 for the proposed UI/UX application. The SUS testing score for the LMS Celoe website falls within Quadrant C, indicating an acceptable level of acceptance with a grade C scale and a rating of "Good. " On the other hand, the SUS testing score for the proposed UI/UX application falls within Quadrant B, with an acceptable level of acceptance, a grade B scale, and an "Excellent" rating.

Felder Silverman Learning Style INTRODUCTION elkom University, through its Learning Management System (LMS), supports the achievement of learning competencies and benefits in online learning through online discussion forums. Learning through forums can help solve problems, enhance the understanding of specific realities, foster respect for otherAos opinions, and provide various types of learning variations. It is known to enhance learning motivation, stimulate students' thinking abilities, and offer flexibility in terms of location, time, and learning style . According to a preliminary research validation survey conducted with 37 respondents, 86. 5% of the participants accessed Telkom University's LMS discussion forum using a PC, while 13. 5% preferred to access it through a Therefore, a less-responsive LMS interface on smartphones significantly affects user experience (UX). However, an interactive and well-designed UI/UX can increase user engagement and satisfaction when Received on 06 Jul 2023. Revised on 14 Jul 2023. Accepted and Published on 12 Dec 2023 HNW SYAHUDA NAHATMASUNI ET AL. UI/UX DESIGN FOR STUDENT DISCUSSIONA utilizing a discussion forum . In addition to the issue of the less responsive LMS interface, students expressed dissatisfaction with the forum discussion feature. The features of the LMS discussion forum were limited to each course and class. Moreover, the LMS forum is confined to formal discussions based on classes and specific course themes. These limitations restrict students from accessing information and create a narrow and rigid discussion ecosystem. To overcome the rigidity of the existing discussion forum in E-Learning LMS, previous researchers have attempted to implement and adopt features from social media within E-Learning LMS . This approach fosters interactive relationships between teachers and students. Another factor that influences the intensity of the student learning atmosphere is studentsAo learning styles. Previous researchers have adopted learning styles in elearning . , and the results have shown that incorporating learning styles into e-learning can facilitate students' reception of learning information. The challenge lies in accommodating different user learning styles in the application development process and, ensuring that users are effectively facilitated when using the application. One model of student learning style is the Felder-Silverman Learning Style Model. Based on the facts and data presented above, the researcher proposes designing a prototype mobile application for student discussion forums using the Design Thinking methodology and adopting a Felder-Silverman Learning Style (FSLS). II. LITERATURE REVIEW The design of application based on Design Thinking is capable of addressing various challenges in problemsolving . The development of web design using Design Thinking greatly facilitates users in carrying out activities on the web . Additionally. UI/UX design can enhance the attractiveness and user satisfaction when using an application, as seen in examples such as the discussion forum in the Plant Trading application . and the student discussion forum . Through the design thinking method, user experience testing can identify several issues and design solutions in the form of prototypes for the emerging problems. Azmi et al. , 2019 . and Batmetan, 2018 . have successfully addressed the identified problems. RESEARCH METHOD As mentioned earlier, the prototype application utilizes the Design Thinking methodology and adopts the FSLS learning style. Design thinking is a human-centered method for problem-solving that aims to bring forth new innovations . Design thinking is also known as a comprehensive thinking process that focuses on creating solutions by starting with empathy towards specific needs of the intended users, resulting in sustainable innovations based on user needs. In its implementation, this method consists of five stages: . Emphatize: Questionnaire. Emphaty Mapping Diagram Define: User Persona and Affinity Mapping Diagram Ideate: Requirement Analysis and Conceptual Diagram Prototype: Userflow. Color Component and Style Guildelines. Wireframe and Mockup Testing: SUS Testing In the testing evaluation, the researcher used SUS testing. The System Usability Scale (SUS) is one of the most popular usability testing methods. SUS was first introduced by John Brooke in 1986. Testing with SUS can generate a usability scale for an application that is effective, reliable, and cost-efficient to use. In the testing process. SUS presents 10 questions with 5 answer choices. Users can respond by selecting a score from 1 to 5. INTL. JOURNAL ON ICT VOL. NO. DECEMBER 2023 ranging from strongly disagree to strongly agree. The minimum possible score for SUS is 0, while the maximum score is 100 . The System Usability Scale has three advantages. First, the testing process is easily understandable by Second, it can involve a small sample size yet yield maximum results. Third, it can clearly differentiate between usable and unusable applications. The System Usability Scale follows a clear calculation procedure for evaluating applications, ensuring that the testing results have accuracy and accountability . The method adopted in the design of LMS is FSLS learning style. Adoption of FSLS, student can use LMS by the background student behaviour profile, so by using LMS will make precisely targets its user. The Felder Silverman Learning Style Model (FSLS) is a learning style created by scientists Felder and Silverman . The model was initially developed by Felder and Solomon . , with the Felder Silverman model making modifications to the original model, particularly in terms of the dimensions of student learning. These dimensions are divided into four categories: the active-reflective dimension . ow students process informatio. , the sensing-intuitive dimension . ow students perceive informatio. , the visual-verbal dimension . he type of information input that is easily understood by student. , and the sequential-global dimension . ow students achieve understandin. In the design process, the researcher used Figma. The stages begin with Empathize, followed by Define. Ideate. Prototype, and Testing. During the Ideate stage, the researcher developed ideas for integrating the FSLS into the application prototype using a Conceptual Diagram. IV. RESULTS AND DISCUSSION As mentioned in the previous section, there are five stages when using Design Thinking methodology . The following provides an overview of each stage: Emphatize The researcher distributed questionnaires to 53 respondents using open- and closed-ended questions. From the questionnaires, 11 main problem points were identified: LMS Celoe . imited features, lack of response feedback, lack of guidance for users, especially novice users, unresponsive mobile web display, unattractive appearance, and feature limitation. , and discussion forums . imited posting features, lack of interaction or response from other users regarding the post by the thread starter, issues with discussion post notifications, inability to view previous discussions, difficulty in finding desired discussion forums, and unattractive/inactive discussion forum.

UI/UX DESIGN FOR STUDENT DISCUSSIONA After distributing the feedback questionnaire for the LMS Celoe, the researcher administered a follow-up questionnaire called the Index of Learning Style (ILS), consisting of 44 questions commonly used to identify a student's learning style model. Of the eight indicators, with four indicators for each result, combinations were calculated, resulting in 70 indicator combinations. From the data analysis of the ILS questionnaire, only 15 learning style models were identified, as shown in TABLE 1. Furthermore, the researcher designed an Empathy Map based on the collected feedback to visualize the existing problems. Fig. Primary User Persona Define At this stage, a User Persona is created to obtain a definitive understanding of the problems by utilizing an imaginary user profile that aligns with the scope of the issues faced by users in the field. In designing the User Persona, the researcher developed three personas, including one Primary User Persona and two Secondary User Personas. The example of User Persona, such as Primary User Persona as shown in Figure 1. Additionally, the researcher depicts the problems by mapping them using an Affinity Map Diagram as shown in Figures 2 and 3. Fig. Part of Affinity Map #1 INTL. JOURNAL ON ICT VOL. NO.
