Rancang Bangun “Alsycode” Dengan Pendekatan Problem Based Leraning Untuk Pembelajaran Algoritma Pemrograman Di SMKS Antartika Surabaya

Abstract

Abstrak:  Pembelajaran Informatika di SMKS Antartika Surabaya masih didominasi pendekatan teacher-centered learning, ditambah dengan  keterbatasan fasilitas komputer di laboratorium sekolah, sehingga siswa kurang memperoleh kesempatan belajar mandiri dan praktik dalam memahami konsep algoritma pemrograman yang bersifat abstrak. Kondisi tersebut menunjukan perlunya media pembelajaran yang dapat digunakan secara fleksibel, mencakup aspek pembelajaran sekaligus praktik. Penelitian ini bertujuan mengembangkan media pembelajaran berbasis web Alsycode (Algoritma Learning System) pada materi Algoritma Pemrograman serta menguji kelayakan dan pengaruhnya terhadap hasil belajar siswa. Media dikembangkan menggunakan model ADDIE dengan pendekatan Problem Based Learning (PBL) dan teknologi Laravel 11, PHP 8.2, MySQL, Tailwind CSS 4, serta Skulpt. Penelitian menggunakan desain one-group pretest-posttest dengan sampel 24 siswa kelas X TKJ 2. Hasil validasi memperoleh persentase 83% dari ahli media dan 84% dari ahli materi dengan kategori sangat layak. Respon siswa berdasarkan Technology Acceptance Model (TAM) mencapai 87% (sangat positif). Nilai rata-rata pretest meningkat dari 43,96 menjadi 85,42, dengan N-Gain 0,73 (tinggi). Uji paired sample t-test menunjukkan Sig. (2-tailed) = 0,000 < 0,05, sehingga Alsycode layak dan efektif meningkatkan hasil belajar algoritma pemrograman.

Abstract:  Informatics learning at SMKS Antartika Surabaya is still dominated by a teacher-centered learning approach, coupled with limited computer laboratory facilities, resulting in limited opportunities for students to engage in independent learning and practice in understanding the abstract concepts of programming algorithms. These conditions indicate the need for a flexible learning medium that supports both learning activities and practical implementation. This study aimed to develop a web-based learning medium called Alsycode (Algorithm Learning System) for the Programming Algorithm topic and to evaluate its feasibility and effect on students' learning outcomes. The media was developed using the ADDIE model with a Problem-Based Learning (PBL) approach and implemented using Laravel 11, PHP 8.2, MySQL, Tailwind CSS 4, and Skulpt. The study employed a one-group pretest-posttest design involving 24 tenth-grade students of the TKJ 2 class. The validation results showed scores of 83% from the media expert and 84% from the subject matter expert, both categorized as highly feasible. Student responses based on the Technology Acceptance Model (TAM) reached 87%, indicating a very positive level of acceptance. The average pretest score increased from 43.96 to 85.42, with an N-Gain score of 0.73 (high category). The paired-sample t-test yielded a significance value of 0.000 (p < 0.05), indicating that Alsycode is feasible and effective in improving students' learning outcomes in programming algorithms.
