Abstract

The utilization of natural fibers such as banana stem fiber and coconut fiber is still not widespread even though both have good mechanical properties. This study aims to compare the tensile strength of the two types of fibers using the hanging load test method. The study was conducted experimentally at the Physics Education Laboratory of Syiah Kuala University using four specimen groups with 20 samplesin each group (n = 20). The process includes drying the fibers indoors, cutting samples with a size of 20 cm for single fibers and 15 cm for bundles, measuring the diameter using a screw micrometer, and applying a load gradually until the fiber breaks. A total of 80 specimens were tasted using a purposive sampling technique, consisting of sigle banana fibers, sigle coconut fibers, banana fiber bundles, and coconut fiber bundles with relatively similar physical characteristics and diameters. The data obtained were analyzed descriptively using average values of stress, strain, and elastic modulus. The results showed that single coconut fiber had the highest stress of 4.49×10⁶ Pa, an elastic modulus of 2.30×10⁸ Pa, and a strain of 0.0210. Meanwhile, single banana fiber had a stress of 4.34×10⁶ Pa, a modulus of 3.57×10⁸ Pa, and a strain of 0.0017. Coconut fiber bundles showed a stress of 1.76×10⁶ Pa, a modulus of 1.29×10⁸ Pa, and a strain of 0.0145, while banana fiber bundles produced a stress of 1.77 × 10⁶ Pa, a modulus of 6.91 × 10⁸ Pa, and a strain of 0.0033. Coconut fiber was more elastic and less prone to breaking during testing, while banana fiber was stiffer and more prone to breaking. The results of this study concluded that coconut fiber is better suited for applications requiring flexibility, while banana fiber is better suited for applications requiring high stiffness.

Abstract

AbstractChanges in teaching and learning practices during and after the pandemic have highlighted the need for instructional materials that support independent learning, enhance student engagement, and foster critical thinking skills. However, physics instruction in schools is still largely dominated by conventional teaching methods, resulting in suboptimal student achievement, particularly in the topics of temperature and heat. Therefore, this study aimed to investigate the effect of a self-regulated learning (SRL)-based learning module integrated with the inquiry learning model on students’ learning outcomes. This study employed an experimental method using a pretest-posttest control group design. The research sample consisted of two classes, namely an experimental class and a control class, each comprising 10 students selected through cluster random sampling. The research instrument was a set of 12 validated essay questions. Data were analyzed using normality tests, homogeneity tests, hypothesis testing, and N-Gain analysis at a significance level of 0.05. The results of the hypothesis test revealed a significant effect of the inquiry-based learning model and the self-regulated learning module on students’ learning outcomes. The obtained t-value (4.974) at the 0.05 significance level was higher than the t-table value (2.024), indicating that H0 was rejected and H1 was accepted. The difference in learning outcomes between the experimental and control groups was also supported by the N-Gain scores, where the experimental class achieved a score of 0.50, higher than the control class score of 0.32. These findings indicate that learning using self-regulated learning modules is more effective than conventional teaching methods. Overall, the module had a significant effect on improving students’ understanding of temperature and heat concepts.Keywords: learning module; self-regulated learning; inquiry learning model; learning outcomes. AbstrakPerubahan praktik pembelajaran selama dan pascapandemi menuntut adanya bahan ajar yang mampu mendukung pembelajaran mandiri, meningkatkan keterlibatan siswa, serta mengembangkan kemampuan berpikir kritis. Namun, pembelajaran fisika di sekolah masih didominasi metode konvensional yang menyebabkan hasil belajar siswa pada materi suhu dan kalor belum optimal. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh modul pembelajaran berbasis self regulated learning (SRL) dengan menggunakan model inquiry learning terhadap hasil belajar siswa. Penelitian ini menggunakan metode eksperimen dengan desain pretest-posttest control group design. Sampel penelitian terdiri atas dua kelas, yaitu kelas eksperimen dan kelas kontrol yang masing-masing berjumlah 10 siswa dan dipilih menggunakan teknik cluster random sampling. Instrumen penelitian berupa tes esai sebanyak 12 soal yang telah divalidasi oleh ahli. Teknik analisis data menggunakan uji normalitas, uji homogenitas, uji hipotesis, dan uji N-Gain pada taraf signifikansi 0,05. Hasil uji hipotesis menunjukkan adanya pengaruh signifikan penggunaan model pertanyaan dan modul pembelajaran self-regulated terhadap hasil belajar siswa. Nilai thitung (4,974) pada taraf signifikansi 0,05 lebih besar dibandingkan ttabel (2,024), sehingga H0 ditolak dan H1 diterima. Perbedaan hasil belajar antara kelas eksperimen dan kontrol juga didukung oleh nilai N-Gain, di mana kelas eksperimen memperoleh skor 0,5, lebih tinggi dari skor 0,32 pada kelas kontrol. Temuan ini menegaskan bahwa pembelajaran berbasis modul self-regulated lebih efektif daripada metode konvensional. Secara keseluruhan, modul tersebut berpengaruh signifikan dalam meningkatkan pemahaman siswa mengenai materi suhu dan kalor.Kata kunci: modul pembelajaran; self regulated learning; model inquiry learning; hasil belajar.

Abstract

Abstract The low physics learning outcomes of students are triggered by the use of conventional learning models and the minimal use of innovative learning media. This study aims to review whether the learning outcomes of students taught using the guided inquiry model with Powtoon media are higher than the learning outcomes of students taught using conventional learning models on the material of work and energy at SMA Negeri 2 Percut Sei Tuan. The research method applies a quasi-experimental two-group pretest-posttest design. The research sample with simple random sampling includes two classes, namely class X-G as an experimental class taught using the guided inquiry model assisted by Powtoon and class X-H as a control class using conventional learning. The research instrument in the form of a multiple-choice test of 15 questions was given through a pretest and posttest to review student learning outcomes. Data collection techniques were carried out through tests. Data analysis techniques applied normality tests, homogeneity tests and hypothesis tests. The results showed that the average post-test score for the experimental class was 81.437, while the control class was 71.875. A one-tailed hypothesis test then conducted, showing a significant difference in the learning outcomes of students in the experimental and control classes, where the average post-test score for the experimental class was higher than that of the control class. This shows that the implementation of the guided inquiry model assisted by Powtoon is effective in improving student learning outcomes. Therefore, the use of innovative learning models supported by interactive media can be an appropriate alternative to improve the quality of physics learning in schools.Keywords: guided inquiry; powtoon; learning outcomes; physics education; work and energy. AbstrakRendahnya hasil belajar fisika siswa yang dipicu pemanfaatan model belajar konvensional dan minimnya pemanfaatan media belajar inovatif.
