PENGEMBANGAN LKPD BERORIENTASI PENDEKATAN STEM

PADA MATERI PERTUMBUHAN DAN PERKEMBANGAN TANAMAN

UNTUK MELATIH KETERAMPILAN BIO-ENTREPRENEURSHIP

THE DEVELOPMENT OF STUDENT WORKSHEET INTEGRATED BY STEM APPROACH

IN PLANT GROWTH AND DEVELOPMENT MATERIAL

TO TRAIN BIO-ENTREPRENEURSHIP SKILLS

Lembar Kerja Peserta Didik (LKPD) pendekatan Science, Technology, Engineering, and Mathematic/ STEM dikembangkan sebagai alternatif bahan ajar baru yang dapat memberikan pengalaman hidup bertema wirausaha biologi terkait hidroponik Wick. Tujuan penelitian ini menghasilkan produk LKPD pendekatan STEM materi pertumbuhan dan perkembangan tanaman untuk melatih keterampilan bioentrepreneurship ditinjau dari kelayakan teoretis dan empiris. Penelitian pengembangan menggunakan model 4D yaitu tahap define, design,  develop, dan disseminate. Parameter penelitian meliputi kelayakan teoretis berdasarkan validitas produk, sedangkan kelayakan empiris merujuk hasil penerapan LKPD pada kelompok kecil peserta didik kelas XII berdasarkan level keterbacaan grafik Fry dan angket respons. Hasil pengembangan LKPD pada kelayakan teoretis mendapatkan validitas sebesar 3,65 dengan kategori sangat valid. Kelayakan empiris berdasarkan ujii keterbacaan menghasilkan level 12 menunjukkan informasi dalam LKPD mudah dipahami peserta didik kelas XII dan mendapatkan respons positif sebesar 95%. LKPD ini memenuhi aspek kelayakan teoretis dan empiris sehingga dapat digunakan sebagai alternatif bahan ajar biologi pendekatan STEM untuk melatih keterampilan bioentrepreneurship peserta didik.

Kata kunci : LKPD, STEM, bioentrepreneurship, pertumbuhan perkembangan tanaman, hidroponik Wick.

The student worksheet based on Science, Technology, Engineering, and Mathematics / STEM approach was developed as an new teaching materials that can provide life experiences with the theme of biological entrepreneurship related to Wick hydroponics. This research aim was to produce student worksheets based on the STEM approach in plant growth and development material to train Bio-entrepreneurship skills in terms of theoretical and empirical feasibility. The development research used the 4D model started from define, design, develop, and disseminate. The research parameters measured from theoretical feasibility based on product validity, while empirical feasibility based on the results of the worksheet implementatiton in a small group of the 12^th-grade student based on the level of Fry graph readability and the questionnaire responses. The results of the worksheet development on theoretical feasibility got a validity score of 3.65 with a very valid category. Empirical feasibility results based on the readability test at the 12^th level, indicated that the information in the student worksheet was easily understood by 12^th-grade students and got 95% of positive responses. This worksheet occupied the theoretical and empirical feasibility aspects so it was able to be used as an alternative teaching material developed using the STEM approach to trained students' Bio-entrepreneurship skills.
