Abstract
ABSTRAK
This research aims to produce PjBL model students^ worksheets to develop students^ science process skills in Calorimeter teaching material in the context of making tape from sweet potatoes. The research method used is the Design and Development Research method, including analysis, planning, production and evaluation stages. At the analysis stage, an analysis of the basic competencies in the 2013 curriculum was carried out. At the planning stage, LKS designs were made. At the production stage, experimental optimization was carried out, namely making tape from sweet potatoes, developing LKS using the PjBL model and developing science process skills. Optimization was carried out to determine the optimum results of the experiment in making tape from sweet potatoes to be used as a basis for developing the PjBL model worksheet on calorimeter material. Based on the optimization results, the most optimum temperature was obtained, namely the temperature that was easy for students to read in the tape fermentation experiment. As an evaluation stage, the worksheet that had been developed was tested for suitability by 2 lecturers and 1 chemistry teacher, followed by a comprehension test involving 20 class XI students at SMAN Margahayu. The results of the LKS feasibility test showed that the LKS developed was very feasible with a score of 98.1%. The comprehensibility test results obtained a score of 99%, indicating that almost all students can understand the worksheet in developing students^ science process skills.
