The purpose of this study is to analyze the effect of the application of the guided inquiry learning model on activities of students, the products of student learning, students' skills in critical thinking, and student reactions to chemical equilibrium material. The design of this study applies a one-group pretest-posttest design. Thirty students of the eleventh grade at Kemala Bhayangkari 1 Surabaya Senior High School were used as the subject of this study. The percentage of application of each phase of the guided inquiry learning model are meetings 1, 2, and 3 was 96.9%, 98.6, and 100%, respectively. Student activities support the application model with a percentage of the total relevant activities of 92.69%. Student learning outcomes on factors that affect the shift in the direction of chemical equilibrium with n-gain obtained a score of 80%, which is high in the category. The results of students' skills in critical thinking in every phase with a high n-gain score are 53.33% interpretation, 40% inference, 63.33% analysis, 60% explanation, and 80 % evaluation. The student responses have a very good category with 99.15%.

This study aims to analyze the effectiveness of the guided inquiry learning model on the student's critical thinking skills on the sub-material factors that affect the rate of reaction. The research uses a quantitative method of pre-experimental type with the one-group pretest-posttest design. The instrument used implementation observation sheets, student learning activities, skills pretest-posttest questions, cognitive pretest-posttest questions, and response questionnaires. The research showed some findings. Firstly, the guided inquiry learning model implementation at the first meeting got a percentage of 97.4%, the second meeting it was 93.4%, with a very good category. Secondly, student activities during the learning process that get a larger percentage are more relevant than those that are not relevant—thirdly, improving critical thinking skills based on the significance of 0.000 below 0.05 so that it is accepted. Fourth, the cognitive domain learning outcomes of 11th grade MIPA 4 students at SMAN 19 SURABAYA score 75, which is declared complete with an average n-gain value of 0.85 and classical completeness of 100%. Finally, student responses to the applied learning model were very good, with a percentage of 99.6%.

In the study, the basic material for making bioplastics was corn starch with the addition of kaolin, microcrystalline cellulose, and chitosan as filler variations, as well glycerol as a plasticizer. The method used was the blending method. The characterization included the absorption test for water resistance, biodegradation test, tensile and elongation strength test, and functional group analysis using FTIR. Among fillers, the best bioplastic characteristic bioplastic was obtained with filler kaolin with the water absorption value of 88.62%, a tensile strength value of 1.44 x10-3 MPa, and the elongation strength value of 5.04%. Nearly 80% of the material was degraded in 15 days. Spectra of FTIR showed the appearance of some functional groups from starch, filler, and plasticizer, which meant that the process of bioplastic manufacturing was physical mixing.
