Abstract

Students' misunderstandings and low level of active involvement in learning chemical equilibrium and the incomplete application of problem-based learning models. This study was motivated by students' misconceptions and low active involvement in learning chemical equilibrium material. In addition, the implementation of the problem-based learning model has not been fully realized, and students still experience difficulties in connecting and applying chemical concepts to everyday life. The purpose of this study is to develop a problem-based learning e-worksheet with prompting question techniques on chemical equilibrium material that is valid and practical. The method used is research and development (R&D) with the Plomp model, which includes the preliminary research and prototyping phases. Validity analysis techniques were analyzed using Aiken's V scale, and practicality analysis techniques were analyzed using a percentage formula. The validity analysis yielded an average score of 0.925, which is considered valid. The practicality test results showed that the e-worksheet is highly practical, with an average score of 94.375% from teachers and 89.38% from students. Based on the results of the study, it can be concluded that the development of an e-worksheet based on problem-based learning with prompting question techniques on chemical equilibrium material is valid and very practical.

Abstract

Although environmental sustainability issues have received increasing attention in consumer behavior studies, studies that specifically discuss the effectiveness of green marketing strategies in influencing Generation Z’s purchase intention in nonmetropolitan areas remain limited. This study aimed to analyze the influence of green marketing, green brand trust, and green brand image on Generation Z’s purchase intention for Miniso products in Padang City. This study used a quantitative approach with a survey design, involving 190 respondents selected using purposive sampling. Data were collected using a questionnaire and analyzed through multiple linear regression using SPSS. The results showed that green marketing had no significant effect on purchase intention, whereas green brand trust and green brand image had positive and significant effects. This finding contributes to the development of the Theory of Planned Behavior and expands understanding of consumer behavior in the context of sustainable marketing. Thus, this study affirms that trust and environmentally friendly brand image play an important role in shaping Generation Z’s purchase intention, so companies need to strengthen their environmental credibility and positioning to improve the effectiveness of sustainable marketing strategies.
