Abstract

This study aims to develop teaching materials in the form of Student Activity Sheets (LKPD) which are integrated in Science, Technology, Engineering, Arts and Mathematics – Project-Based Learning (STEAM-PjBL) on Acids and Bases material and are used to determine the level of validity and practicality of the LKPD that is used. developed. This research is a research (R&D) with a 4-D development model. This 4-D model has four stages, namely the stages of define, design, develop and disseminate. However, the dissemination stage was not carried out. This study used instruments in the form of content and construct validation questionnaires, teacher and student response questionnaires. This LKPD was validated by five experts consisting of a Chemistry lecturer (FMIPA UNP) and a chemistry teacher. The validation data obtained were analyzed using the v Aiken scale, while the practicality data were analyzed using a comparison of students' scores with students' maximum scores. Based on the validation questionnaire that has been analyzed, it can be concluded that the LKPD developed is valid with a v value of 0.86 with a very valid category. While the practicality of teachers and students obtained NP values of 0.85 and 0.89 with very practical categories.

Abstract

Penelitian ini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) Hakikat Ilmu Kimia berbasis Etnosains terintegrasi STEAM (Science, Technology, Engineering, Arts and Mathematics) pada pembelajaran di SMA dan mengungkapkan kategori validitas dan praktikalitas LKPD yang dihasilkan. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan 4-D (Define, Design, Development and Disseminate) namun tahap disseminate tidak dilakukan. Instrumen pengumpulan data menggunakan lembar validasi yang diberikan kepada 5 validator serta angket praktikalitas kepada 2 orang guru kimia dan 25 peserta didik. Data validitas diolah menggunakan rumus skala Aiken’s V dan data praktikalitas diolah menggunakan rumus %NP. Hasil penelitian validitas diperoleh rata-rata sebesar 0,897 dengan kategori valid, sedangkan hasil praktikalitas terhadap guru dan peserta didik diperoleh presentase rata-rata 94% dan 95% dengan kategori sangat praktis. Sesuai dengan hasil penelitian disimpulkan bahwa LKPD yang dikembangkan valid dan praktis sehingga bisa diterapkan pada pembelajaran.
