Abstract

Coffee is one of Indonesia's export commodities which has an important role ineconomic growth in Indonesia. Coffee production from 2020 to 2022 will experiencefluctuations. As for the causes of errors in post-harvest that are not appropriate to obtaingood quality coffee beans, post-harvest handling is needed by carrying out the sortingprocess, washing process, drying process and roasting process. The ADDIE method isused in developing this tool, including: Analysis stage, analyzing the need to develop aproduct and analyzing the feasibility and requirements for product development, Designstage, designing and designing a product. Development stage, development of productdesign. Implementation stage, realizing the design of a development product, testing theproduct developed in learning. Evaluation stage, evaluating the results of the productdeveloped and its application in the classroom. Validation data from three media expertson the props developed obtained an average percentage of 91.8%, meaning that they arevery suitable for use as props. And the validation results from three material experts on thetools and practice manual obtained an average percentage of 85.92%, which means it isvery suitable for use as a practice guide for teaching aids. Based on the average valuefrom the validation of media experts and material experts, the coffee bean sorting teachingaid shows that the criteria obtained are very feasible and the results of student responsesget a value with very practical criteria for use as a learning medium. The choice of materialsand design in making practical equipment has been taken into account, apart from usingmaterials that are not easily damaged, the shape is also made simple.

Abstract

Differentiated teaching modules are designed to provide learningexperiences that are more appropriate to students' learning styles and focus onstudent-centered learning. Therefore, students with different interests andtalents can obtain learning material in the same class but in different ways, oneof which can be identified by looking at the learning style of each student. Theaim of this research is to determine the level of feasibility and user response toteaching modules to assist differentiated learning in sound wave material. Thistype of research is descriptive quantitative with the development model used isADDIE, which involves five stages: Analysis, Design, Development,Implementation, and Evaluation. The instruments used were interview sheetsand assessment questionnaires in the form of validation from media experts,material experts, summative tests and user responses. Researchers used theresults of assessment questionnaires and interviews to make it easier to drawconclusions. Based on the analysis results, the average percentage value ofthe three validations is 86.2%. The teaching module developed is very worthyof the valid category. The results of responses from users of the teachingmodule for learning differentiation of sound wave material from physics subjecteducators at SMA Negeri 1 Batanghari, SMA Negeri 1 Metro, and MAMuhammadiyah Metro obtained an average percentage score of 88.1% with thecriteria "very good".

Abstract

Abstract: The purpose of this study was to determine the application of problem based learning can improve problem solving skills This study used classroom action research, using 2 research cycles with each cycle being implementation, application, observation, and reflection. The research instruments used were lesson plans, and student worksheets. The implementation of learning is done through five stages. Stage 1: Directing students to the problem, stage 2: Organizing students during the learning process, stage 3: Assisting independent and group investigations, stage 4: Developing and presenting work and exhibitions, stage 5: Evaluating and reflecting on the learning process. This application has assessment results taken from the value of student worksheets in cycle I is 75.00, 81.25, and 87.50 with each of these values then included in the good category. Whereas in cycle II the values were 87.50 and 93.25 in the very good category. The application of problem-based learning can improve the problem solving ability of students in class XI IPA SMA Muhammadiyah 2 Metro on light waves material in the form of understanding problem-based concepts.
