VALIDITAS DAN KEPRAKTISAN LKPD BERBASIS KETERAMPILAN PROSES SAINS DASAR MATERI KEANEKARAGAMAN HAYATI KELAS X SMA

VALIDITY AND PRACTICALITY OF STUDENT WORKSHEETS BASED ON BASIC SCIENCE PROCESS SKILLS OF BIODIVERSITY TOPIC FOR SENIOR HIGH SCHOOL GRADE 10^TH

Abstrak

Materi keanekaragaman hayati membahas objek-objek yang telah dikenal oleh peserta didik karena berada dekat di sekitar peserta didik. Oleh karena itu, lebih mudah mengajarkan keterampilan proses karena objek yang dipelajari dapat dijumpai di kehidupan sehari-hari. Namun hingga saat ini belum ada LKPD untuk materi keanekaragaman hayati yang sekaligus melatihkan keterampilan proses. Penelitian ini bertujuan untuk mengembangkan LKPD berbasis keterampilan proses sains dasar materi keanekaragaman hayati kelas X SMA yang valid dan praktis. Penelitian pengembangan ini merujuk pada model pengembangan 4-D (define, design, develop, and disseminate), tanpa tahap disseminate. Validitas LKPD ditinjau berdasarkan validasi para ahli, yaitu ahli materi, ahli pendidikan, dan ahli media. Kepraktisan LKPD ditinjau berdasarkan penilaian guru (n = 5) dan respons peserta didik (n = 16). Data dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa LKPD berbasis keterampilan proses sains dasar yang dikembangkan pada materi keanekaragaman hayati mendapatkan skor rata-rata keseluruhan aspek validitas sebesar 93% yang tergolong dalam kategori sangat valid. Selanjutnya pada hasil respons oleh peserta didik mendapatkan skor rata-rata 98% dan hasil respons guru biologi mendapatkan skor rata-rata 97% yang tergolong dalam kategori sangat baik. Oleh karena itu, LKPD berbasis keterampilan proses sains dasar materi keanekaragaman hayati yang dihasilkan sangat layak untuk digunakan pada pembelajaran biologi untuk materi keanekaragaman hayati.

Kata Kunci: validitas LKPD; kepraktisan LKPD; keterampilan proses sains dasar; keanekaragaman hayati

Abstract

The material on biodiversity discusses objects that are already known by students because they are located near students. Therefore, it is easier to teach process skills because the object learned can be found in everyday life. However, to date there is no worksheet for biodiversity topic that also processes skills. This research aimed to develop worksheet based on the science process skills of basic biodiversity materials for grade X high school, which is valid and practical. This development research referred to the 4-D development model (define, design, develop, and disseminate), without the disseminate stage. The validity of worksheet was reviewed based on the validation of experts, namely material expert, education expert, and media expert. The practicality of worksheet was reviewed based on teacher assessment (n = 5) and student responses (n = 16). Data were analyzed descriptive-quantitatively. The results showed that the worksheet based on basic science process skills developed on biodiversity material gained an average score of all aspects of validity of 93%, which was classified as very valid. Furthermore, the results of responses by students get an average score of 98% and the results of responses of biology teachers got an average score of 97%, which was classified as very good. Therefore, the worksheet based on the basic science process skills of the biodiversity material produced was very feasible to be used in learning biology for biodiversity material.

Key words: worksheet validity; worksheet practicality; basic science process skills; biodiversity
