Abstract

This research was motivated by the importance of a learning media that can improve students chemical literacy skills by connecting additive material with phenomena that occur in everyday life. This study aimed to produce an educational game in the form of chemical adventure media which has characteristics such as modified game rules from adventure games and monopoly, equipped with questions, obstacles in chemical literacy-oriented games which include the use of additives, impacts, consumption limits and Islamic view of good foods for consumption. This study used the Design Based Research (DBR) method. The validation test results of the chemical adventure media product were valid with an average rcount of 0.80, with 0.84 on the presentation aspect of the material content and 0.76 on the display aspect. This shows that the chemical adventure media is valid and can be used as a learning media.

Abstract

Chemistry subject is an abstract and theoritical material. One of them is in the nomenclature of inorganic compounds. Student will find it difficult to understand the material if the learning process uses inappropriate learning media. Thus, it can reduce student attractiveness and interest in learning. The use of cheminosmart media can help students understand the nomenclature of inorganic compounds. Students will collaborate and be fully involved in a cheminosmart game match. The purpose of this study was to describe the appearance of the product and to analyze the results of the cheminosmart media validation test on the nomenclature of inorganic compounds. The research method used was Design Based Research (DBR) using flowchart instruments, story boards and validation questionnaires. The results of the validation test showed that the average value of rcount was 0.87, so that the cheminosmart game media is declaired valid and can be used as an effective learning media.

Abstract

This study aims to describe the preparation of project-based worksheets on the manufacture of facial toner from lime peel distillate (Citrus aurantifolia) and to analyze the results of the validity test of the Worksheet format on making facial toner from lime peel distillate (C. aurantifolia). The method used is Design. Based Research (DBR), with three stages 1) Analysis 2) Design 3) Development. The instrument used was a validation test questionnaire using the correlation technique. The results of the project-based worksheet validation test are declared valid with an average value of rcount of 0.85 which is included in the high validity category, thus the worksheet can be used to help the learning process on cosmeseutical material.

Abstract

This study aims to describe the appearance of project-based worksheet products and to analyze the results of project-based worksheet validation tests on the utilization of fermented date palm waste as raw material for date coffee drinks. This research method is Design Based Research (DBR), with three stages, namely analysis, design, development. These stages include analysis of fermentation chemicals, analysis of literature on the content of date seeds, literature analysis of fermented coffee processing research, analysis of steps on project-based worksheets and then linking experimental procedure design to developing project-based worksheets. The instrument used was a validation test questionnaire using the correlation technique (r). The results of this research are in the form of a project-based worksheet product on the use of fermented date coffee waste as raw material for date coffee drinks, with a validation test result of a mean count of 0.87. Thus the resulting project-based worksheets are declared valid and worthy of being used as learning media.

Abstract

The experiment in making innovative products that have benefits for everyday life is one of the efforts to face the challenges of the 21st century. One of the innovative products related to the concept of colloids and which can be made easily by students is antimicrobial liquid soap. During its development, the experiment required worksheets to direct students to the concepts to be studied and make it easier for students to carry out experiments. As for answering the challenges of the 21st century, the experimental worksheets that are made must be able to construct students' critical and creative thinking skills. To achieve this goal, the experimental worksheet is arranged with problem-based learning stages. This study aims to describe the stages of the development of problem-based worksheets on the manufacture of antimicrobial liquid soap from lemon zest (Citrus limon) extract and to analyze the results of the validation test. The research method used is design based research (DBR) and literature. Worksheets are arranged through analysis and development stages. The design stage is replaced by the library method. The worksheets that are arranged have a display in the form of discourse and questions that are arranged based on the stages of problem-based learning. Based on the results of the validation test, an average rcount of 0.76 was obtained, which means that the worksheets prepared were valid and could be used in Basic Chemistry practicum on colloid material.
