Abstract

The development of the times demands an increase in the quality of human resources, including in the field of education. Students need to have a well-facilitated learning experience to make it easier to understand the material. Understanding learning materials can be made easier through reflection activities as a support for the repetitive method. Through reflection activities, students can recall the material and even the learning process that has been passed, so that the material will be more embedded in memory. The purpose of this study was to determine student responses to reflection activities. The research method used is a quantitative research method. The researcher used a questionnaire with a Likert scale rating as a research instrument. The data collection technique is in the form of a questionnaire technique. The researcher used purposive sampling technique and got 23 students who contracted the Educational Psychology course at the Science Education Department, Manado State University. The results showed that the students strongly agreed with the implementation of reflection activities in learning.

Abstract

The research aims to improve the learning outcomes of grade 9.7 students of Manado 7 Public Middle School through the implementation of problem based learning multimedia learning models. The lack ability of students to think, understand, and solve problems, exacerbated by the situation after the Covid-19 pandemic resulted in disrupted learning activities, so learning multimedia is needed that can optimize learning outcomes and facilitate the learning process. Using the classroom action research method, the research subjects were 34 students. Conducted in two cycles with four stages: planning, action, observation, and reflection. Data were analyzed using the formula P=????/????x100%. The results of the analysis show an increase in learning outcomes, as well as the ability to solve problems. This increase can be seen from the increase in classical completeness in each cycle, from an average of 65 cycles I to 82 in cycle II. Increasing the percentage of learning outcomes is 26%. The number of students fulfilling the minimum completeness criteria is 67% or 23 students (cycle I), to 94% or 32 students (cycle II). Student completeness from cycle I to cycle II increased by 27%.

Abstract

This study aims to develop teaching materials in the form of comic media for excretory system material, grade VIII junior high school in science subjects. This development research uses the ADDIE model which consists of the stages of analyze, design, development, implementation, and evaluation. From the results of the study in the form of a percentage of product validity from the validation sheet obtained from the test results by material experts, media experts, teachers and limited trials on students at SMP Negeri 3 Tompasobaru. The validation results from material experts show that the level of validity of the product that has been developed with a percentage of 96% which is in the very feasible category, media experts with a percentage of 95.29% which is in the very feasible category, from teachers with a percentage of 92% which is in the very feasible category and the results of a limited trial with a percentage of 96.66% in the very good category. So it can be concluded that the teaching materials in the form of comic media on excretory system material for class VIII junior high school students are very valid and feasible to use

Abstract

This research aims to investigate students' interest in learning through the project-based learning model. The study was conducted at the Department of Biology Education and the Department of Science Education at Manado State University. The research method employed was quantitative descriptive. The subjects consisted of 20 students participating in project-based learning in the instructional media course. Data were collected through a learning interest questionnaire distributed at the end of the semester and measured using a Likert scale. The results indicated that for 12 statement items, the percentage fell within the range of 81%-100%, indicating a high level of interest among all respondents. Therefore, it can be concluded that the implementation of the project-based learning model effectively stimulates and optimizes students' learning interest.

Abstract

Spent coffee grounds are an abundant organic waste material. Spent coffee grounds have significant potential as an environmentally friendly alternative energy source in bio-battery technology. This study aims to analyze the effect of KOH molarity concentration on the electrical properties of coffee ground-based bio-batteries. Variations in KOH molarity solutions of 1M, 3M, and 5M, each mixed with 50 grams of spent coffee grounds, were utilized to evaluate their effect on the electrical properties, including current, voltage, and power output. The results indicate that increasing the molarity concentration significantly enhances the bio-battery's performance, as evidenced by increased voltage and maximum power output. The highest electrical power output, 97.2 mW, was achieved at a 5M KOH concentration. The study concludes that selecting the appropriate molarity concentration is a key factor in optimizing the performance of coffee ground-based bio-batteries. This research contributes to the advancement of renewable energy development from organic waste.
