Abstract

This development research aims to develop LKM green chemistry physics chemistry practical worksheet based on case method as supplementary teaching materials for students of the Chemical Education study program at Sriwijaya University using the 4STMD (Four Step Teaching Materials Development) method. The steps of the 4STMD method, namely the first stage is the selection stage, carried out by analyzing needs, curriculum and analyzing the material by looking for references in various sources. The second stage, namely the structuring stage, is carried out by adding or subtracting material and compiling the material. The third stage is the characterization stage, carried out by developing the results of material analysis. The fourth stage is the didactic reduction stage, but the researcher did not carry out the didactic reduction stage. Data collection techniques used in the form of interviews, pre-research questionnaires and validation questionnaires. In the material validation test, the validity of teaching materials was obtained based on the Aiken coefficient of 0.75 which was categorized as high. Based on these results, it shows that the development of LKM Green Chemistry Physics Chemistry Practical Worksheet Based on Case Method has met the valid criteria.

Abstract

This study alims to analyze consumer standards for Amanda Brownies product packaging using the BackMarking and House of Quality methods. The results of the study indicate that there are 19 criteria that are consumer standards for the product packaging. In competitor analysis, BackMarking identified the malin competitors in the Amanda Brownies UKM product packaging category. Based on the results of the House of Quality analysis, the normalized ralw weight value shows the grealtest demand from consumers regarding Amanda Brownies packaging design, with al value range between 0.013. Several criteria that are consumer priorities in packaging design are Attractive Packaging Shape (B1), Packaging that Displays Expiration Date Clearly (B7), Packaging Material Thickness (B16), and Packaging that Displays Slogan/Tagline (B19). In designing packaging products, the technical elements that are the malin priority are Letter Color Variants (Priority 1), Writing Font Dimensions (Priority 2), Color Variants (Priority 3), and Tagline Description (Priority 4). These findings provide important insights for the development of Amanda Brownies product packaging that suits consumer needs and preferences.
