Penelitian ini merupakan pengembangan dari makalah yang telah dipresentasikan pada Seminar Internasional namun menggunakan tipe cermin yang berbeda dan berbasis Graphical User Interface (GUI). Penelitian ini bertujuan untuk menghasilkan simulasi pembentukan bayangan pada cermin cembung sebagai media pembelajaran Fisika yang dapat digunakan secara mudah dan efektif. Penelitian ini bersifat studi literatur, dengan menggunakan metode komparatif antara hasil simulasi dan hasil analitik. Simulasi dalam penelitian ini dibuat menggunakan aplikasi Scilab 5.5.0 dengan GUI Builder versi 3.0, dengan memanfaatkan konsep Fisika dan Matematika, di mana cermin cembung disimulasikan menggunakan persamaan parametrik untuk lingkaran, sedangkan sinar-sinar istimewa disimulasikan menggunakan persamaan garis lurus dengan gradien tertentu. Dalam penelitian ini disimulasikan pembentukan bayangan dari sebuah benda dengan tinggi 7cm yang diletakkan pada jarak 15cm dari sebuah cermin cembung yang memiliki radius kelengkungan -30cm. Cermin cembung yang disimulasikan dalam penelitian ini diasumsikan sebagai sebuah permukaan datar. Simulasi yang telah dibuat dapat berjalan dengan baik pada Scilab 5.5.0. Dari hasil simulasi ini, diperoleh tinggi bayangan sebesar 3.5cm dan jarak bayangan sebesar -7.5cm. Hasil perhitungan ini dibandingkan dengan hasil perhitungan secara analitik, dan diperoleh error perhitungan sebesar 0%, dengan kata lain hasil tersebut sama dengan hasil yang diperoleh dengan cara analitik, dan sekaligus membenarkan pernyataan bahwa proses pembentukan bayangan pada cermin cembung lebih mudah untuk digambarkan apabila cermin tersebut dianggap sebagai sebuah permukaan datar. Dengan demikian, simulasi ini dapat digunakan dalam proses pembelajaran Fisika.References
