Abstract

As time goes by and technology advances, any information can be easily obtained from many media, both from various print media or digital electronic media. One of the fastest growing digital media and the main choice for individuals or agencies to get fast and accurate information is the website. One of the benefits of the website is that it can be used as an effective promotional media because it can be accessed by anyone and at any time. This study discusses the evaluation of school websites with a case study at the SMK Muhammadiyah 1 Banjarmasin using the WebQual 4.0 and Importance-Performance Analysis (IPA) methods. This study aims to measure user ratings of performance and expectations of users/visitors to the website of the SMK Muhammadiyah 1 Banjarmasin. The data in this study were obtained from the questionnaire using a sample of web visitors themselves, both through online based questionnaires and offline questionnaires with paper. This study uses data processing software, namely Structural Equation Modeling (SEM) 2.0. It can be concluded that in this study the results are measured by the level of performance (actual) and the level of importance (expectations) which shows that there is an overall gap for all dimensions -0.38 ie the website needs improvement and tends to still not be as expected. The biggest gap is in the Usability dimension with the largest value being -1.07 on USE5 variables, which means that the appearance of this website tends to be unattractive, not in line with expectations, and needs improvement. Then the acquisition of the value of R Square for the variable user satisfaction is 0.61, which means that the value indicates that the variable user satisfaction can be explained by usability, information quality, and service interaction with a value of 67.7%, while the remaining 32.3% is influenced by variables others not found in the research model.

Abstract

The importance of expertise in the field of programming today makesVocational High Schools as early as a possible incorporate curriculum that canlearn skills in programming, which is then called basic programming subjects.These subjects are the initial foundation, to study other productive subjects thatmust be studied by students in the field of ICT expertise. However, in reality,students tend to dislike these subjects because they feel difficulties inunderstanding and learning them. Therefore, we try to present a solution toovercome this problem by developing basic programming educational media,especially in the material of branching control structures by embedding thesyntax of problem-posing learning models in the type of open-posing into theinteraction flow. This educational media is called TOLSYASUPI-EduMed. Theresearch and development method (R&D) was used as the main method in thisstudy. The model for system development uses ADDIE by adapting the R&Dmethod. A/B testing methods are used to validate the initial selection ofeducational media design. The form of design until the development stage isvalidated by media and material experts as much as 3 iterations, to ensure thatthe educational media can look for effects on the effectiveness of learning. Atotal of 36 students were involved in the use of this educational media.Evaluation of the use of educational media to determine aspects of satisfactionand usability using the Computer System Usability Questionnaire (CSUQ)method. The results of the study stated that 90.9% of experts agreed that VeryStrong to choose design B to continue at the advanced design, development,and implementation stages. The results of the validation of media and materialexperts state that it is feasible to use. Based on functional requirementsspecifications, all features function properly, and non-functionally 94.49% withpredicates Very Strong that end-users (students) are satisfied and feel theusefulness of this TOLSYASUPI-EduMed.
