Abstract

This research aims to describe the influence of Syndicate Group Learning Instruction on the improvement of activities and physics learning outcomes of 8th-grade students at SMPN 18 Mataram. The research design employed is an experimental study. The population of this study comprises all 8th-grade students at SMPN 18 Mataram. The sample consists of 22 students from class VIIIA as the experimental group and 24 students from class VIIIC as the control group selected using a random sampling technique. Data for this study were obtained through pre-tests and post-tests given to the sample class students. Data collection techniques involve using observation sheets and formative tests that have been validated for validity, reliability, differential power, and difficulty index. Based on the data analysis, the average pre-test score for the experimental group is 56.13; for the control group, it is 46.66, categorized as homogeneous and normally distributed. The post-test results show an average of 69.31 for the experimental group and 58.54 for the control group. The final test data of the sample class students were analyzed using the t-test, resulting in a calculated t-value of 2.160 and a tabulated t-value of 2.016. The calculated t-value is greater than the tabulated t-value at a 5% error level, thus rejecting the null hypothesis (Ho). It can be concluded that the use of Syndicate Group Learning Instruction has a significant influence on the activities and physics learning outcomes of 8th-grade students at SMPN 18 Mataram.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh metode concept map terhadap hasil belajar siswa dalam mata pelajaran fisika di MA NW Kotaraja. Penelitian ini menggunakan desain eksperimen dengan dua kelompok, yaitu kelompok eksperimen yang diberikan pembelajaran menggunakan metode concept map dan kelompok kontrol yang diberikan pembelajaran dengan metode konvensional. Sampel penelitian terdiri dari 56 siswa kelas X yang dibagi menjadi dua kelompok: 31 siswa di kelompok eksperimen dan 25 siswa di kelompok kontrol. Hasil penelitian menunjukkan bahwa rata-rata nilai post-test siswa di kelompok eksperimen adalah 75 dengan standar deviasi 10, sementara di kelompok kontrol rata-rata nilainya adalah 57 dengan standar deviasi 9. Uji hipotesis menunjukkan bahwa thitung sebesar 7,148 lebih besar dari ttabel sebesar 1,671 pada taraf signifikansi 95%, yang berarti terdapat perbedaan signifikan antara kedua kelompok. Temuan ini mengindikasikan bahwa metode concept map secara signifikan meningkatkan hasil belajar siswa dibandingkan dengan metode konvensional. Rekomendasi untuk penelitian lanjutan termasuk penggunaan peta konsep dalam mata pelajaran lain dan integrasi teknologi dalam pembelajaran. The Influence of Concept Map Method on Student Learning Outcomes at MA NW Kotaraja Abstract This study aims to analyze the influence of the concept map method on student learning outcomes in physics at MA NW Kotaraja. The research employed an experimental design with two groups: an experimental group that received instruction using the concept map method and a control group that received conventional teaching methods. The sample consisted of 56 tenth-grade students, divided into two groups: 31 students in the experimental group and 25 in the control group. The results showed that the average post-test score for students in the experimental group was 75 with a standard deviation of 10, while the control group averaged 57 with a standard deviation of 9. Hypothesis testing revealed that the t-value of 7.148 exceeded the critical value of 1.671 at a 95% confidence level, indicating a significant difference between the two groups. These findings suggest that the concept map method significantly enhances student learning outcomes compared to conventional methods. Recommendations for future research include the application of concept maps in other subjects and the integration of technology in teaching.

Abstract

This study aims to examine the effect of varying vegetable oil compositions (coconut, palm, and olive) on the physical and chemical qualities of solid soap, specifically in terms of hardness, cleansing ability, and moisture content. This study used a laboratory experiment with five soap formulas combining various vegetable oil compositions. The results showed that the formula with a combination of 60% coconut oil and 40% palm oil produced the soap with the highest hardness, while the formula with a combination of 60% coconut oil and 40% olive oil provided the best moisture content. The soap with a composition of 60% coconut oil and 40% palm oil also demonstrated better cleaning ability, thanks to the lauric acid content in coconut oil, which has antibacterial properties. This study recommends the use of a combination of coconut and palm oils to produce soap with the best quality in terms of hardness and cleansing ability, and coconut and olive oils for soap with greater skin moisturizing properties. It is hoped that this research will contribute to the development of the natural soap industry in Indonesia, reduce dependence on imported raw materials, and increase the competitiveness of natural soap products in the global market.
