KEVALIDAN LKPD BERBASIS ETNOSAINS UNTUK MELATIHKAN KETERAMPILAN PROSES SAINS SISWA

THE VALIDITY OF ETHNOSCIENCE-BASED LKPD TO TRAIN THE SCIENCE PROCESS SKILLS OF JUNIOR HIGH SCHOOL STUDENTS

Penelitian ini dilakukan dengan tujuan mengembangkan Lembar Kerja Peserta Didik (LKPD) yang berbasis etnosains untuk melatihkan keterampilan proses sains siswa. Peneliti menggunakan Research & Development (R&D) sebagai jenis penelitian. Batasan penelitian hanyasampaipada uji validitas internal dari perangkat pembelajaran dan LKPD yang dikembangkan. Teknik pengumpulan data yang digunakan peneliti berdasarkan validitas hasil telaah berupa saran dari dosen pembimbing serta hasil revisi oleh peneliti. Sedangkan tehnik analisis data berdasarkan rekapitulasi hasil validasi dari dua validator dengan membandingkan seluruh hasil point kriteria yang diperoleh kemudian dianalisis secara deskriptif kuantitatif. Hasil data validasi berupa penskoran terhadap perangkat pembelajaran dan LKPD berbasis etnosains untuk melatihkan keterampilan proses sains yang dikembangkan. Secara keseluruhan skor rata-rata hasil penelitian berdasarkan validitas memperoleh persentase rata-rata sebesar 88,55 % dari total persentase validasi silabus 88,16%, persentase validasi RPP 90%, dan persentase validasi LKPD 87,5%. Kesimpulan dari penelitian ini adalah LKPD berbasis etnosains layak digunakan sebagai sarana membantu melatihkan keterampilan proses sains siswa.

This research was conducted by the authors with the aim of developing EbSW (Ethnoscience-Based Students Worksheets) to train students' science process skills. Researchers use Research & Development (R&D) as a type of research model. Data collection techniques used by researchers based on the validity of the results of the study in the form of input and suggestions from the supervisor and revision results by the researcher. While the data analysis technique is based on the recapitulation of the results of the validation of the two validators by comparing all the results of the criteria points obtained then analyzed descriptively quantitative. The results of the validation data are scoring of learning tools and ethnics-based LKPD to practice the science process skills developed. Overall the average score of the results of the study based on validity obtained an average percentage of 88.55%. The conclusion of this study is that ethnoscience-based LKPD is appropriate to be used as a means to help train students in the science process skills.

Keywords: LKPD, Ethnoscience, and Science Process Skills.
