Abstract

The number of environmental pollution phenomena that occur in nature has resulted in environmental damage. The cause of environmental pollution is inappropriate waste treatment, one of number is batik industrial wastewater. The factor of awareness and the lack of public knowledge regarding waste management are the things that support this natural damage. So that we need worksheets as a medium in learning that can teachers used to learn how to treat waste properly and correctly. So this study aims to describe the arrangement of student worksheets and to analyze the results of the validation test. The steps used in the student worksheets on the manufacture of biosorbents from papaya seeds (carica papaya l) for the absorption of dyestuffs from the batik industry^s liquid waste based on guided inquiry. The method used is Design Based Research (DBR) by using three stages, namely 1) Analysis, 2) Design, and 3) Development. The instrument used in this study was a validation questionnaire using correlation analysis techniques and a student worksheet based on guided inquiry. The results of the student worksheet validation test obtained an average value of 0.80 which states that the student worksheets are valid and can be used as a medium for learning or practicum activities.
