Pengembangan Lembar Kerja Peserta Didik Berbasis Science, Technology, Engineering, Art and Mathematics (STEAM) pada Materi Prinsip-prinsip Kimia Hijau untuk Peserta Didik Kelas X di MAN 4 Aceh Besar. [Skripsi Universitas Syiah Kuala]. Dibawah bimbingan Dr. Sri Winarni, S.Pd., M.Pd., dan Nur Akmalia, M.Pd.

Inovasi dalam pengembangan bahan ajar diperlukan untuk mendukung pembelajaran yang bermakna dan kontekstual bagi peserta didik. Penelitian bertujuan mengembangkan LKPD Berbasis STEAM pada materi Kimia Hijau sebagai bahan ajar pendukung. Metode yang digunakan adalah Research and Development (R&D) dengan model 4D (define, design, develop, disseminate), yang dibatasi hingga tahap develop. Subjek dalam penelitian ini adalah peserta didik kelas X-2 dan guru di MAN 4 Aceh Besar. Tahap define dilakukan melalui wawancara guru dan penyebaran angket kebutuhan peserta didik, dilanjutkan dengan analisis konsep dan perumusan tujuan pembelajaran. Tahap design mencakup penyusunan struktur isi dan desain awal LKPD. Pada tahap develop, dilakukan validasi ahli terhadap produk, hasil validasi ahli menunjukkan rata-rata persentase kevalidan sebesar 99 % dengan kategori sangat valid. Selain itu, perhitungan validitas isi juga menggunakan pendekatan CVI dengan hasil perhitungan diperoleh nilai i-CVI dan s-CVI sebesar 1,00 dengan kategori sangat tinggi, serta analisis konsistensi antar penilai menggunakan uji IRA dengan nilai 0,91 kategori tinggi. Setelah revisi produk, LKPD yang sudah valid dan reliabel langsung diujicobakan kepada peserta didik di dalam kelas. Kemudian dilakukan penyebaran angket tanggapan kepada guru dan didapat hasil 97 % dengan kategori sangat baik. Penyebaran angket tanggapan kepada peserta didik didapat hasil 92 % dengan kategori sangat baik serta tingkat kepraktisan sebesar 97 % dengan kategori sangat praktis di MAN 4 Aceh Besar. Dengan demikian, LKPD berbasis STEAM dinyatakan layak digunakan untuk tahap penelitian selanjutnya yaitu uji coba skala besar dalam pembelajaran kimia.

Suraiya Samadi (2025). Development of Student Worksheets Based on Science, Technology, Engineering, Art and Mathematics (STEAM) on the Material of Green Chemistry Principles for Grade X Students at MAN 4 Aceh Besar. [Skripsi, Syiah Kuala University]. Under direction of Dr. Sri Winarni, S.Pd., M.Pd., and Nur Akmalia, M.Pd. Innovation in the development of teaching materials is essential to support meaningful and contextual learning for students. This study aims to develop a STEAM-based Student Worksheet on Green Chemistry as a supplementary instructional resource. The method used is Research and Development with the 4D model which include define, design, develop, and disseminate, limited to the develop stage. The subjects of this study were grade X-2 students and teachers at MAN 4 Aceh Besar. The define stage was conducted through teacher interviews and student needs assessments, followed by conceptual analysis and the formulation of learning objectives. The design stage encompassed the structuring of content and the initial design of the worksheet. In the develop stage, expert validation was performed on the product, where the results showed an average validity percentage of 99 percent with a very valid category. Additionally, content validity was calculated using the CVI approach with results obtained for i-CVI and s-CVI values of 1.00 with a very high category, as well as inter-rater consistency analysis using the IRA test with a value of 0.91 and a high category. After product revision, the valid and reliable worksheet was directly field-tested with students in the classroom. Then, response questionnaires were distributed to teachers with a result of 97 percent with a very good category. The distribution of response questionnaires to students obtained a result of 92 percent with a very good category and a practicality level of 97 percent with a very practical category at MAN 4 Aceh Besar. Consequently, the STEAM-based LKPD was declared suitable for use in the next research stage, namely large-scale trials in chemistry learning. Keywords: LKPD, STEAM, 4D, learning material development
