Inovasi dalam pengembangan bahan ajar diperlukan untuk mendukung pembelajaran yang bermakna dan kontekstual bagi peserta didik. Penelitian ini bertujuan mengembangkan handout berbasis Phenomenon Based-Learning (PhBL) 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. 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 handout. Pada tahap develop, dilakukan validasi ahli terhadap produk, hasil validasi ahli menunjukkan rata-rata persentase kevalidan sebesar 87% (kategori sangat valid). Selain itu, perhitungan validitas isi juga menggunakan pendekatan CVI (nilai i-CVI dan s-CVI sebesar 1,00 dengan kategori sangat tinggi), serta analisis konsistensi antar penilai menggunakan uji IRA (nilai 0,63; kategori tinggi). Setelah revisi produk, dilakukan penyebaran angket tanggapan kepada guru (92%; kategori sangat baik) dan peserta didik (89%; kategori sangat baik) di SMAN 1 Meukek. Dengan demikian, handout berbasis PhBL ini dinyatakan valid dan layak digunakan sebagai bahan ajar pendukung dalam pembelajaran kimia.

Innovation in the development of teaching materials is necessary to support meaningful and contextual learning for students. This research aims to develop a handout based on Phenomenon Based-Learning (PhBL) on Green Chemistry topic as a supporting teaching material. The method used is Research and Development (R&D) with the 4D model (define, design, develop, disseminate), limited to the develop stage. The define stage was conducted thru teacher interviews and the distribution of student needs questionnaires, followed by concept analysis and the formulation of learning objectives. The design stage involves preparing the content structure and creating the initial design of the handout. In the develop stage, Expert validation of the product was performed, along with the results of the validation. showing an average validity percentage of 87% (very valid category). In addition, the content validity calculation also used the CVI approach (i-CVI and s-CVI values of 1,00 with a very high category), as well as the inter-rater consistency analysis using the IRA test (value of 0,63; high category). After the product revision, a response questionnaire was distributed to teachers (92%; perfect category) and students (89%; perfect category) at SMAN 1 Meukek. Thus, this PhBL-based handout is declared valid and suitable for use as a supporting teaching material in chemistry education.
