Abstract

English

This study aims to develop a problem-solving-based Electronic Student Worksheet (E-LKPD) in the form of an APK file for Android users and to test its validity, practicality, and effectiveness in improving students' mathematical problem-solving abilities. This study uses a research and development method with data collection instruments in the form of validation sheets, practicality questionnaires, and mathematical problem-solving ability test questions. Product validation was carried out by material experts and media experts. The results of the analysis show that the average validation in the material aspect is 98.66% with the category of "very valid" and in the media aspect is 84.61% with the category of "valid". The practicality test conducted at SMA Negeri 5 Padang obtained a percentage of 88.60% with the category of "very good". The results of the effectiveness test based on the N-Gain analysis showed an average value of 0.6594 or 65.94% with the category of "quite effective". Based on these results, it can be concluded that the developed problem-solving-based E-LKPD meets the criteria of being valid, practical, and quite effective so that it is feasible to be used as an alternative digital learning medium to support the improvement of students' mathematical problem-solving abilities.

Penelitian ini bertujuan untuk mengembangkan LKPD Elektronik (E-LKPD) berbasis problem solving dalam bentuk file APK untuk pengguna Android serta menguji tingkat validitas, praktikalitas, dan efektivitasnya dalam meningkatkan kemampuan pemecahan masalah matematis siswa. Penelitian ini menggunakan metode penelitian dan pengembangan (Research and Development) dengan instrumen pengumpulan data berupa lembar validasi, angket praktikalitas, dan soal tes kemampuan pemecahan masalah matematis. Validasi produk dilakukan oleh ahli materi dan ahli media. Hasil analisis menunjukkan bahwa rata-rata validasi pada aspek materi sebesar 98,66% dengan kategori “sangat valid” dan pada aspek media sebesar 84,61% dengan kategori “valid”. Uji praktikalitas yang dilaksanakan di SMA Negeri 5 Padang memperoleh persentase sebesar 88,60% dengan kategori “sangat baik”. Hasil uji efektivitas berdasarkan analisis N-Gain menunjukkan nilai rata-rata sebesar 0,6594 atau 65,94% dengan kategori “cukup efektif”. Berdasarkan hasil tersebut, dapat disimpulkan bahwa E-LKPD berbasis problem solving yang dikembangkan memenuhi kriteria valid, praktis, dan cukup efektif sehingga layak digunakan sebagai alternatif media pembelajaran digital untuk mendukung peningkatan kemampuan pemecahan masalah matematis siswa.
