Abstract

This study is a development study that uses the 4-D model (define, design, develop, desiminate). Where the results of this study are learning media that can help students understand the material, especially on reflection material. The media developed is Canva media which has passed the validation stage of the readability test and the product cona test until Canva media can be said to be feasible as a learning media that can be distributed to students. The research location is SMP Negeri 1 Telaga Biru, where this media was developed there due to the lack of limited use of learning media and students tend to be taught using books in the absence of other learning resources. This attracted researchers to conduct research at the school. based on the results of the study, the Canva reflection media that has been developed gets a positive response from teachers and students with a teacher response of 100% and students 95%

This study intends to develop interactive learning media based on relationships and functions. The type of research used is development research that aims to produce a product. This study uses the Plomp development model. The sample of this study was eighth-grade students at Public Middle School 1 Bonepantai. The media development instruments in this study were validation sheets for media experts, validation sheets for material experts, and response questionnaire sheets for students and teachers. Data analysis uses quantitative descriptive analysis. The results of the study indicated that validation from media experts and material experts showed that the media met the criteria for being worthy of being tested. In addition, the results of the student response questionnaire on the interactive learning media developed were also positive; this can be seen from the average percentage of the student response questionnaire, which reached 90% with an excellent category, and the results of the teacher response questionnaire reached 91% with an excellent category. Therefore, interactive learning media meets practicality and learning merit criteria.

Abstract

This study aims to investigate the influence of electronic worksheets based on live worksheets on student learning outcomes in the material of systems of linear inequalities with two variables. This research is an experimental study with research subjects classified into two groups: X-Gusdur class as the experimental group and X-ir. Soekarno, as the control group with the population, is SMA Negeri 1 Momunu, using a pre-test and post-test control group research design. Data collection techniques were test instruments based on indicators after the learning process. Pre-tests and post-tests were used to measure student learning outcomes. Data processing used descriptive analysis, showing that the average student learning outcomes in the experimental class were higher than in the control class. The results of the inferential analysis showed that both data were normally distributed and homogeneous; thus, the covariance analysis (ANACOVA) was continued, and results were obtained where Ho was rejected and H₁ was confirmed.From the descriptive analysis, it can be seen that the average learning outcome score in the experimental group was 79.96, which was significantly higher than the average score in the control group, which only reached 69.19. Likewise, the results of hypothesis testing using the ANACOVA test also showed more favorable results for the experimental group with 𝛼 = 0.05 obtained by FcountFtable (12.024.04). Therefore, the research findings in heate that student learning outcomes are higher after being taught using ce on live worksheets than printed worksheets.

Abstract

Noise is a sound that is not desired because it is not in accordance with the context of activity, space, and time so it can cause disturbances to comfort and even human health. Twoof the basic ingredients of a silencer are husk and bran. This research aimed to determine the effect and model of the relationship of the density of the sample mixture of husks and bran on acoustic waves' reflection coefficient and transmission coefficient. The method used in this research is experimental, using a mixture of husk and bran samples whose density consists of 5 variations. The results showed that the husk and bran mixture's sample density strongly affected the reflection coefficient (r = 0.947 to r = 0.966) and the transmission coefficient (r = -0.962 to r = -0.999). These resultsshow that the greater the sample density of the husk and bran mixture, the greater the absorption intensity fraction produced. Statistically, the level of influence is indicated by the correlation coefficient, whose value is around r = 0.95 to r = 0.99. Based on the results, the reflection and transmission coefficients are influenced by the density of the mixture of husk and bran samples.

Abstract

This study aims to enhance the motivation and learning outcomes of high school students at SMA Negeri 7 Gorontalo for the 2022/2023 Academic Year through implementing android-based learning media on temperature and heat materials. The research method is a quasi-experimental design with a one-group pretest-posttest research design. The research sample consisted of 3 classes: class X IPA 2 as the experiment class and class X IPA 3, and X IPA 4 as a replica class. This research begins with preparing learning tools to implement learning media based on Android material on temperature and heat. The results of the validation show that the learning tools are valid and can be used in the learning process. Implementing the learning process in this study is in the very good category. It can increase student motivation and learning outcomes, where the N-Gain scores for the experimental and replica classes are in the high category.
