Abstract
This study is a developmental research of Chemistry Practicum Guidebook Integrated Problem Based Learning Model (PBL). This study aims to obtain (1) The feasibility of Chemistry Practicum Guidebook Class SMA/MA published by two different publishers, (2) the validity of Chemistry Practicum GuidebookIntegrated Problem Based Learning Model (PBL)which developed on Chemistry material Class XI in Odd semester, (3) the differences of increasing student learning outcomes using Chemistry Practicum Guidebook Integrated Problem Based Learning Model (PBL)with student learning outcome using practicum guidebook in school, (4) the differences in improving student learning outcomes in terms of science process skills, and (5) the interaction between the implementation of Chemistry Practicum Guidebook Integrated Problem Based Learning Model (PBL) and conventional chemistry practicum guidebook with the level of science process skills in affecting student learning. The population in this study were all students of class XI MAN 2 Deli Serdang. The sample selection in this study used purposive sampling technique. The sample in this study were students of class XI MIA 2 as an experimental class and XI MIA 1 as a control class. Validator of Chemistry Practicum Guidebook Integrated Problem Based Learning Model (PBL) that has been developed is two lecturers ofUnimed Postgraduate Chemistry Education and two teachers in MAN 2 Deli Serdang. The study results showed that: (1) the results of the chemistry practicum guiding validation obtained an average of 3.13 for publisher A and an average of 3.26 for publisher B; 2) the validation of chemistry practicum guidebook developed by integrating Problem Based Learning Model (PBL)obtained an average of 3.66 is very valid (very feasible) to be used; (3) the improvement of student learning outcome using Chemistry Practicum Guidebook Integrated Problem Based Learning Model (PBL)are different with student learning outcome using practicum guidebook in school with a significances level (sig.) <&
