Abstract
This study aims to develop problem-solving based teaching materials (LKPD) with to business and energy materials. This type of research is development research / research and development. The development model used in this research is the 4D model, namely define, design, develop, and disseminate. Testing of problem solving-based student worksheet development products with a scientific approach is carried out through validation from material experts, media experts, subject matter teachers, and student questionnaire responses. The data technique used non-test (questionnaire and expert validation sheet). The technique of analyzing data from the distribution of questionnaires was carried out by tabulating the data from each validator, calculating the average score, and comparing the total score with a scale of five. Based on the results of 3 material experts, it shows that the quality of the LKPD is in the feasible category with a percentage value of 80%. Meanwhile, the results of 3 media experts show that the quality of LKPD is in the decent category with the proportion of the value of 77.15%. And based on the results of 2 subject teachers, it shows that the quality of the LKPD is in the decent category with a proportion of 82.5%. Meanwhile, the cost of student responses is in the very good category with an actual score of 78.4.

Summary
Sejarah Artikel Diterima: Oktober 2020 Direvisi: Desember 2020 Dipublikasi: Desember 2020. Penelitian ini bertujuan untuk mengembangkan bahan ajar (LKPD) berbasis problem solving pada materi usaha dan energi. Pengujian produk pengembangan LKPD berbasis problem solving dengan pendekatan saintifik dilakukan melalui validasi dari ahli materi, ahli media, guru mata pelajaran, dan angket respon siswa.Teknik pengumpulan data menggunakan non-tes (angket dan lembar validasi ahli). Dan berdasarkan hasil penilaian dari 2 orang guru mata pelajaran menunjukkan bahwa kualitas LKPD termasuk dalam kategori layak dengan persentase nilai 82,5%. B. (2020), Pengembangan Bahan Ajar (LKPD) Berbasis Problem Solving pada Materi Usaha dan Energi. Faktor lain yang menyebabkanya juga yaitu kurangnya kesiapan sekolah, guru dan peserta didik untuk melakukan problem solving dalam pembelajaran. Salah satu faktor yang dapat meningkatkan semangat belajar siswa yaitu penggunaan bahan ajar LKPD berbasis problem solving dengan pendekatan saintifik, karena materi pembelajaran dibahas berdasarkan aktifitas sehari-hari siswa sehingga siswa dapat memecahkan masalah dengan mudah. Untuk menganalisis data yang didapatkan, peneliti menggunakan konversi skor aktual menjadi skala 5, sebagai berikut: Tabel 1.Konversi Skor Aktual Menjadi Skala 5
