PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) SUHU DAN KALOR MENGGUNAKAN MEDIA PEMBELAJARAN GOOGLE SITES BERBASIS PROBLEMBASED LEARNING (PBL) UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH 

DEVELOPMENT OF STUDENT WORKSHEETS (LKPD) TEMPERATURE AND HEAT USING GOOGLE SITES LEARNING MEDIA BASED ON ROBLEMBASED LEARNING (PBL) TO IMPROVE PROBLEM-SOLVING SKILLS

Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis Problem-Based Learning (PBL) dengan memanfaatkan media pembelajaran Google Sites pada materi suhu dan kalor guna meningkatkan kemampuan pemecahan masalah siswa SMP. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan 4D (Define, Design, Develop, Disseminate). Subjek penelitian melibatkan siswa kelas VII di SMP Negeri 1 Ngoro dan Al-Akbar Junior High School. Hasil penelitian menunjukkan bahwa LKPD yang dikembangkan memenuhi kriteria valid, praktis, dan efektif. Validitas LKPD dinilai oleh validator dengan persentase kevalidan mencapai 93%, sementara kepraktisan LKPD terlihat dari keterlaksanaan pembelajaran yang mencapai 90-98%. Efektivitas LKPD dibuktikan melalui peningkatan nilai N-gain kemampuan pemecahan masalah siswa, dengan rata-rata N-gain sebesar 0,310 pada indikator memahami masalah. Selain itu, respon siswa terhadap LKPD juga positif, menunjukkan bahwa LKPD berbasis Problem-Based Learning dengan Google Sites dapat menjadi alternatif pembelajaran yang menarik dan efektif.

This study aims to develop Problem-Based Learning (PBL)-based Learner Worksheets (LKPD) by utilizing Google Sites learning media on temperature and heat material to improve junior high school students' problem-solving skills. The research method used is Research and Development (R&D) with the 4D development model (Define, Design, Develop, Disseminate). The research subjects involved seventh-grade students at SMP Negeri 1 Ngoro and Al-Akbar Junior High School. The results showed that the developed LKPD met the criteria of valid, practical, and effective. The validity of the LKPD was assessed by validators with a percentage of validity reaching 93%, while the practicality of the LKPD was seen from the implementation of learning which reached 90-98%. The effectiveness of the LKPD is evidenced by the increase in the N-gain value of students' problem-solving skills, with an average N-gain of 0.310 on the indicator of understanding the problem. In addition, students' responses to the LKPD were also positive, indicating that Problem-Based Learning LKPD with Google Sites can be an interesting and effective learning alternative.
