Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran problem based learning berorientasi green chemistry pada materi hidrolisis garam untuk mengembangkan soft skill konservasi siswa SMA. Metode penelitian ini adalah research and development (R&D). Hasil penelitian menunjukkan LKS yang dikembangkan sangat layak untuk digunakan dalam pembelajaran kimia. Perangkat pembelajaran dapat meningkatkan pemahaman konsep siswa materi hidrolisis garam dengan N-gain sebesar 0,63 (sedang). Peningkatan soft skill konservasi siswa yang berkriteria tinggi sebanyak 35,48 % sedangkan yang berkriteria sedang 64,52 %. This research has aim to developt teaching and learning instrument application on problem based learning which oriented on green chemistry on salt hydrolisys for developing conservation soft skill for student. The method of this research is research and development (R&D). The results showed a very worthy worksheets developed for use in teaching chemistry. Teaching instrument can improve the understanding of student concept of salt hydrolysis matery can get N-gain 0,63 (medium). The improving soft skill of student conservation has high criteria 35,48%. For medium has 64,52%.
