Abstract

Mathematics, particularly trigonometry, is often perceived by high school students as abstract and difficult to understand due to the complex spatial visualization it requires. Conventional teacher-centered instruction, which primarily emphasizes memorizing formulas, frequently fails to foster a strong conceptual understanding, resulting in low student motivation. This study aims to design, develop, and evaluate an interactive educational game called TrigoSolver as an alternative learning medium for trigonometry. The application was developed using the Unity Engine with the C# programming language and the Agile (Scrum) software development methodology, which supports iterative and adaptive development. The game incorporates a Pythagorean Triples algorithm based on Euclid's formula to dynamically generate trigonometry problems through Procedural Content Generation (PCG) while avoiding irrational numbers. It also includes an automatic fraction-answer validation feature to improve the learning experience. The system was evaluated through Black Box Testing to verify functional correctness and a User Acceptance Test (UAT) using a Likert-scale questionnaire developed based on the ISO/IEC 25010 software quality standard and the Technology Acceptance Model (TAM). The Black Box Testing results confirmed that all game functionalities operated as intended without errors. The UAT, involving seven subject-matter and media experts, yielded an overall feasibility score of 82.57% (classified as "Feasible") with excellent instrument reliability (Cronbach's Alpha = 0.922). These findings indicate that TrigoSolver is a feasible alternative learning medium for helping students visualize abstract trigonometric concepts, including sine, cosine, and tangent. Nevertheless, further improvements to the user interface and navigation are recommended to enhance the overall user experience.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengevaluasi software Visual Studio Code, serta untuk menilai dan menganalisis seberapa baik Visual Studio Code memenuhi berbagai aspek usability menurut kriteria yang dikemukakan oleh Jakob Nielsen. Tujuan utama dari pengukuran usability adalah untuk memastikan bahwa perangkat lunak dapat digunakan dengan efisien, efektif, dan memuaskan oleh pengguna yang dituju. Penelitian ini menggunakan metode Nelsen's Attributes of Usability terdiri dari aspek learnability, efficiency, memorability, error, serta satisfaction. melibatkan 93 responden berjumlah 34,8% perempuan dan 65,2% laki laki. Data dikumpulkan melalui kuesioner yang dibagikan kepada pengguna Visual Studio Code. Hasil penelitian menunjukkan bahwa Visual Studio Code memiliki nilai learnability, efficiency, dan memorability yang tinggi. Namun, nilai errors dan satisfaction masih tergolong rendah. Dari perolehan keseluruhan total evaluasi usability terdapat 3,06 % (Netral) dari penilaian sekala likert. Berdasarkan penelitian yang dilakukan, dapat disimpulkan bahwa software visual studio code mudah untuk digunakan, hanya saja perlu sedikit perbaikan pada tampilan yang dimiliki saat ini.
