Abstract

This research aims to determine the effect of using learning media assisted by Smart Apps Creator (SAC) on students' cognitive learning outcomes on the human circulatory system material at SMP Negeri 2 Suwawa. The research method used in this study was an experiment using a One Group Pretest-Posttest Design with a population of all VIII grade students of SMP Negeri 2 Suwawa. The sample consists of 3 classes, namely the experimental class, replication 1 and replication 2, with a purposive sampling technique. Data was obtained by statistical tests and inferential statistics, including normality tests, hypothesis tests, and N-Gain analysis. The results of the average acquisition of class VIII students were greater than the KKTP, shown by the average value of the experimental class of 84.48, replication class 1, 81.14 and replication class 2, 86.45, compared to the KKTP of 75. Based on the hypothesis testing criteria, where the t count in the experimental class was 10.969 compared to the t table of 2.045, replication class 1 obtained a t count of 6.710 with a t table of 2.074, and replication class 2 obtained a t count of 9.569 with a t table of 2.093. It can be concluded that the hypothesis testing in the three classes is that the tcount is greater than the ttable. This can be interpreted as the use of learning media assisted by Smart Apps Creator influences students' cognitive learning outcomes.

Abstract

The learning model can be interpreted as a whole series of material presentations that include all aspects before, during and after learning. This study aims to examine the effect of applying a cooperative model integrated with local wisdom values on the mastery of the concept of simple aircraft research at SMP Negeri 1 Telaga Biru. The research design used a One-Shot Case Study by using one class as a sample. The results showed a significant increase in student learning outcomes after being treated using a cooperative model integrated with local wisdom values. The use of cooperative models integrated with local wisdom values increases the active involvement of students in discussions and cooperation, so as to improve understanding of concepts and the ability to carry out activities that are directly related to the concept of simple aircraft material. Data analysis shows that the average posttest score is higher than the learning objectives achievement criteria (KKTP). The results showed the criteria for testing the hypothesis of a one-sample t-test, tcount ≥ ttable, with α level = 0.05 for the experimental class, t table value (2.0096). This indicates that the cooperative model integrated with local wisdom values can improve students' learning outcomes in understanding the concept of simple aircraft material. This study concludes that the application of the cooperative model integrated with local wisdom values is effective because it involves students actively in the process of cooperation and discussion, thus strengthening their understanding of the material and achieving learning outcomes.

Tegangan tembus merupakan salah satu parameter penting dalam sistem isolasi listrik yang menentukan batas kemampuan suatu medium dalam menahan medan listrik sebelum terjadi pelepasan muatan listrik (breakdown). Material elektroda yang digunakan dalam sistem bertegangan tinggi sangat mempengaruhi distribusi medan listrik dan nilai tegangan tembus yang dihasilkan. Oleh karena itu, penelitian ini dilakukan untuk mengkaji karakteristik tegangan tembus dari berbagai jenis material elektroda dalam medan listrik seragam. Studi ini secara khusus membandingkan empat jenis logam, yaitu stainless steel, aluminium, tembaga, dan kuningan, yang umum digunakan dalam aplikasi kelistrikan. Pengujian dilakukan secara eksperimental di Laboratorium Tegangan Tinggi dengan menggunakan konfigurasi elektroda bola-bola, jarum-jarum, dan pelat-pelat pada medium udara. Hasil pengujian menunjukkan bahwa material elektroda memiliki pengaruh signifikan terhadap besar tegangan tembus. Stainless steel secara konsisten menunjukkan performa terbaik dengan nilai tegangan tembus tertinggi pada semua konfigurasi, yakni 8,07 kV (bola-bola), 8,21 kV (jarum-jarum), dan 6,37 kV (pelat-pelat). Sebaliknya, tembaga menghasilkan tegangan tembus terendah, khususnya pada konfigurasi pelat-pelat sebesar 3,27 kV. Aluminium dan kuningan menunjukkan hasil yang bervariasi, namun masih di bawah performa stainless steel

Abstract

Collaborative learning has the potential to address these challenges by promoting problem-solving through collective participation within groups. This research investigates the effect of the Jire Collaborative Learning model integrated with Phylearn media on students’ learning outcomes regarding heat and temperature. The study was motivated by low student achievement, primarily attributed to conventional teaching methods to engage students in active participation. This quasi-experimental research employed a one-group pre-test-post-test design involving 25 seventh-grade students at SMP Negeri 4 Monano. The Jire Collaborative model emphasizes active student collaboration, while Phylearn provides interactive multimedia support to help visualize abstract scientific concepts. The findings reveal a significant improvement in students’ cognitive performance (levels C2-C4) after the intervention, indicating that the integrated approach effectively improves conceptual understanding. This influence is demonstrated by the difference in students’ learning outcomes before and after applying the JIRE model, where the average pre-test score of 46.4 increased to 81.05 in the post-test. The t-test results indicate that this difference is statistically significant, with a significance value of 2.10, less than 0.05. These findings confirm a significant difference between students’ pre-test and post-test scores after applying the JIRE collaborative learning model, indicating that this model effectively improves students’ learning outcomes. These results suggest that technology-supported collaborative learning is a promising strategy for improving the quality of science education at the junior high school level.
