Abstract

Penelitian ini dilatarbelakangi oleh rendahnya minat dan hasil belajar siswa pada sub materi bilangan oksidasi kelas sepuluh, MAN 1 Kubu Raya, akibat kurangnya pemahaman konsep reaksi redoks. Oleh karena itu, diperlukan model pembelajaran yang tepat untuk meningkatkan pemahaman siswa. Penelitian ini bertujuan untuk menganalisis perbedaan minat dan hasil belajar siswa serta efektivitas pembelajaran berbantuan Ludo Kimia dengan model TGT pada materi reaksi redoks. Menggunakan desain Non-equivalent Control Group, tes awal dilakukan pada kelompok kontrol dan eksperimen. Hasil analisis menunjukkan perbedaan signifikan antara pretest dan posttest dengan nilai gain 0,84, yang menunjukkan efektivitas model TGT berbantuan Ludo Kimia.

Abstract

Penelitian ini bertujuan untuk mengetahui validitas, kepraktisan, dan keefektifan modul larutan penyangga berbasis Higher Order Thinking Skills (HOTS) di kelas XI MAN 3 Pontianak. Penelitian menggunakan metode Research and Development (R&D) dengan model pengembangan 4D (Define, Design, Develop, Disseminate) yang dibatasi sampai tahap develop. Subjek penelitian adalah 8 siswa kelas XI MAN 3 Pontianak. Teknik pengumpulan data menggunakan lembar validasi ahli, angket respon siswa dan guru, serta tes Higher Order Thinking Skills (HOTS). Data dianalisis menggunakan analisis persentase dan effect size (Cohen’s d). Hasil penelitian menunjukkan bahwa modul memiliki tingkat validitas sangat tinggi, dengan persentase aspek bahasa 97%, media 89%, dan materi 82,5%. Modul juga dinilai praktis dengan rata-rata respon siswa 83,7% dan guru 80,3% sehingga menunjukkan bahwa modul mudah digunakan dan menarik serta mendukung pengembangan High Order Thinking Skills (HOTS) siswa. Uji keefektifan menunjukkan peningkatan hasil belajar dari rata-rata 22,5 (pretest) menjadi 79,25 (posttest) dengan effect size (Cohen’s d) sebesar 6,09, yang termasuk kategori sangat besar. Dengan demikian, modul larutan penyangga berbasis HOTS terbukti valid, praktis, dan sangat efektif digunakan dalam pembelajaran kimia untuk meningkatkan hasil Higher Order Thinking Skills siswa.

Abstract

This study aims to develop a Triplet Card learning media for hydrocarbon material for Grade XI students of SMA Negeri 1 Bonti. The study employed the ADDIE development model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were Grade XII students of SMA Negeri 1 Bonti who were involved in the media trial. The trials were carried out in two stages, namely a small-group trial involving 6 students and a large-group trial involving 30 students in one class. The instruments used consisted of validation sheets from material experts, media experts, and language experts, as well as response questionnaires for teachers and students. Data collection techniques were conducted through expert validation and the distribution of questionnaires in both trial stages. The results showed that the Triplet Card learning media obtained a high level of validity, with an average score of 88% for the material aspect, 93% for the media aspect, and 91% for the language aspect. The practicality test also indicated very positive responses, with 97% from the teacher and 88% from students. Thus, the Triplet Card is declared valid and practical based on the practicality test conducted.

Abstract

This study aims to develop an Environment-Based Practicum E-Module for green chemistry and to evaluate its validity, practicality, and effectiveness. The study employed a Research and Development (R&D) method using the three-dimensional (3-D) development model, which consists of the Define, Design, and Develop stages. The participants were 28 tenth-grade students from Class X-A at SMAS Mujahidin Pontianak. Data were collected through interviews, classroom observations, expert validation sheets, student response questionnaires, and pretest–posttest assessments. The effectiveness evaluation in the Develop stage employed a one-group pretest–posttest design, with students completing a pretest before using the e-module and a posttest after the learning intervention. The data were analyzed using percentage analysis to determine the validity and practicality of the e-module, while its effectiveness was evaluated using the Normalized Gain (N-Gain) index. The results indicated that the developed e-module achieved average validity scores of 96% from material experts, 98% from media experts, and 98% from language experts, all of which were classified as highly valid. The practicality evaluation yielded an average score of 84%, indicating that the E-Module was highly practical. In addition, the effectiveness test produced an average N-Gain score of 0.86, which falls within the high category, as reflected by the increase in students' mean scores from 85 on the pretest to 98 on the posttest. These findings demonstrate that the Environment-Based Practicum E-Module is valid, practical, and effective, making it a suitable digital instructional resource for supporting green chemistry learning, particularly in schools with limited laboratory facilities.
