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%. © 2014 Prodi Pendidikan IPA FMIPA UNNES Semarang.
