PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK PURIGAMI BERBASIS PROBLEM BASED LEARNING PADA MATERI PERUBAHAN LINGKUNGAN UNTUK MELATIH KETERAMPILAN PEMECAHAN MASALAH SISWA KELAS X

STUDENTS' WORKSHEETS DEVELOPMENT PURIGAMI BASED ON PROBLEM BASED LEARNING ON ENVIRONMENTAL CHANGE MATERIAL TO TRAIN PROBLEM SOLVING SKILLS OF GRADE X STUDENTS

Pembelajaran Problem Based Learning (PBL) banyak diterapkan di sekolah pada materi perubahan lingkungan dengan menggunakan permasalahan kontekstual untuk melatih keterampilan memecahkan masalah. Salah satu sumber belajar yang dapat di manfaatkan peserta didik adalah buku panduan pengelolaan kompos berjudul Purigami (Pupuk Organik Limbah Jerami) dalam kegiatan PPK ORMAWA tahun 2022. Sumber belajar tersebut belum dilengkapi dengan LKPD, sehingga perlu dikembangkan LKPD yang dapat membantu kelancaran pembelajaran. Tujuan penelitian ini mengembangkan LKPD Purigami dalam pembelajaran PBL pada materi perubahan lingkungan untuk melatih keterampilan pemecahkan masalah. Parameter validitas yang diukur meliputi aspek penyajian, aspek isi, keterkaitan dengan PBL, keterkaitan indikator pemecahan masalah, dan aspek bahasa. Metode penelitian ini menggunakan model pengembangan 4D (Define, Design, Develop, Disseminate) mencakup analisis kebutuhan, desain struktur LKPD, pengembangan konten, dan evaluasi. Data dianalisis secara deskriptif kuantitatif.  Hasil penelitian ini memperoleh LKPD yang memiliki kekhasan yaitu fitur Let’s Find Out, Let’s Quest. Let’s Inves, Let’s Convery, Let’s Reflect, Eco-Detect, Eco-Hypothesize, Eco-Investigate, Eco—Conclusion sehingga peserta didik dilatih keterampilan pemecahan masalah terkait perubahan lingkungan dengan langkah-langkah PBL baik materi maupun praktiknya. Hasil validasi LKPD berdasarkan aspek penyajian sebesar 100% kategori sangat valid, aspek isi 97,7% dengan kategori sangat valid, aspek keterkaitan dengan PBL sebesar 100% kategori sangat valid, keterkaitan dengan indikator pemecahan masalah sebesar 100% kategori sangat valid, dan aspek bahasa sebesar 100% kategori sangat valid. Diperoleh rata-rata validitas semua aspek 99,5% kategori sangat valid. Kesimpulan penelitian adalah telah dikembangkan LKPD Purigami yang dapat melatih keterampilan memecahkan masalah terkait limbah jerami dengan pembuatan kompos organik dan layak digunakan dalam pembelajaran sesuai dengan Kurikulum Merdeka.

Problem Based Learning (PBL) learning is widely applied in schools on environmental change material using contextual problems to train problem-solving skills. One of the learning resources that can be utilized by students is a compost management guidebook entitled Purigami (Organic Fertilizer for Straw Waste) in the 2022 PPK ORMAWA activities. This learning resource is not yet equipped with LKPD, so it is necessary to develop LKPD that can help smooth learning. The purpose of this study is to develop LKPD Purigami in PBL learning on environmental change material to train problem-solving skills. The parameters measured include presentation aspects, content aspects, relevance to PBL, relevance to problem-solving indicators, and language aspects. This research method uses the 4D development model (Define, Design, Develop, Disseminate) including needs analysis, LKPD structure design, content development, and evaluation. The data were analyzed descriptively quantitatively. The results of this study obtained LKPD which has the characteristics of Let's Find Out, Let's Quest. Let's Invest, Let's Convert, Let's Reflect, Eco-Detect, Eco-Hypothesize, Eco-Investigate, Eco-Conclusion so that students are trained in problem-solving skills related to environmental change with PBL steps, both in terms of material and practice. The results of the LKPD validation based on the presentation aspect were 100% in the very valid category, the content aspect was 97.7% in the very valid category, the aspect of relevance to PBL was 100% in the very valid category, the relevance to problem-solving indicators was 100% in the very valid category, and the language aspect was 100% in the very valid category. The average validity of all aspects was 99.5% in the very valid category. The conclusion of the study is that the Purigami LKPD has been developed which can train problem-solving skills related to straw waste with the making of organic compost and is suitable for use in learning according to the Merdeka Curriculum.
