Abstract

Kurangnya minat dan pemahaman siswa terhadap kimia, terutama materi Persamaan Reaksi Kimia yang abstrak, menjadi masalah utama di SMA Swasta Sta. Familia. Penelitian ini bertujuan menganalisis efektivitas model Pembelajaran Berbasis Masalah (PBL) dalam meningkatkan hasil dan respon belajar siswa. Menggunakan pendekatan kuantitatif deskriptif (One-Shot Case Study) pada 22 siswa kelas X-1, data dikumpulkan melalui observasi guru, penilaian hasil belajar (tugas, latihan, diskusi), dan angket respon. Hasilnya, kemampuan guru mengelola PBL berkategori baik (reliabilitas 98%). Rata-rata hasil belajar meningkat menjadi 82,5 (melebihi KKM 75) dengan ketuntasan 100%, dan respon siswa sangat positif (83,81%). Disimpulkan bahwa PBL efektif meningkatkan pemahaman dan keterlibatan siswa pada materi kimia abstrak.

Abstract

Limbah tekstil berupa kain bekas merupakan permasalahan lingkungan yang serius akibat sulit terurai dan volumenya yang terus meningkat seiring pertumbuhan penduduk. Inovasi pengolahan limbah rumah tangga melalui pembuatan pot bunga dari kain bekas (Pot Kain Sarbet) hadir sebagai solusi kreatif dan edukatif. Kegiatan yang dilaksanakan di SMA Swasta Sta. Familia Sikumana ini menggunakan pendekatan kualitatif deskriptif dengan metode eksperimen langsung melalui program vokasi. Hasilnya menunjukkan bahwa pot berbahan dasar handuk dan kain perca yang dipadukan dengan semen berhasil dibuat dengan struktur kokoh dan estetika yang baik. Selain mampu mengurangi timbunan limbah tekstil, kegiatan ini juga berhasil mengintegrasikan pembelajaran vokasi dengan pendidikan lingkungan, mengasah kreativitas, ketelitian, serta kemampuan pemecahan masalah peserta. Dengan demikian, inovasi ini tidak hanya menawarkan solusi praktis pengelolaan limbah, tetapi juga mendukung terwujudnya sumber daya manusia yang kreatif, inovatif, dan berwawasan lingkungan.

Abstract

This study aims to examine the effectiveness of Ethnoscience-Based Student Worksheets (EbSWs) on the subject matter of the nature of physics and the scientific method. The research subjects were 10th-grade students at SMAK Sint Carolus Penfui. This is a descriptive quantitative study using tests to measure cognitive learning outcomes and Science Process Skills (SPS), while questionnaires were used to measure student perceptions (attitudes, skills, and knowledge). The results showed that EbSW were effective in optimizing students' SPS, with an overall average score of 83.90 (very skilled) and a high consistency of results (standard deviation/SD = 3.61). Student perceptions were very positive, with knowledge (average 83.7) and attitude (average 82.1) aspects categorized as very good. SPS perception results (average 77.9) were categorized as good and showed an increase in higher-level cognitive skills. Cognitive learning outcomes showed a level of mastery (mean = 80.67) with a cognitive SD of 19.07, indicating a gap in mastery of the material among students, especially in higher-order thinking skills (HOTS). Overall, EbSW are effective for understanding basic concepts and developing SPS evenly but need to be improved to address varying levels of HOTS mastery.

Abstract

This study aims to evaluate the effectiveness of a training project using the Project-Based Learning (PPjBL) model in enhancing elementary school teachers’ competencies in writing and documenting best practices into book chapters. This study employs a mixed-methods approach with a pre-experimental design (one-group pretest–posttest design). The study participants consisted of 9 elementary school teachers selected using saturation sampling. Quantitative data were obtained through pretest and posttest assessments of writing skills, while qualitative data were collected through observations of the implementation of the PPjBL model and perception questionnaires. The results showed a significant improvement in teachers’ writing skills after the training (p < 0.01), particularly in the aspects of content, structure, and academic language. The implementation of the PPjBL model fell into the “mostly implemented” category with an average score of 3.25, indicating that the model’s stages were carried out fairly optimally. In addition, teachers’ perceptions of the PPjBL model fell into the “very positive” category, with an average score of 3.54, particularly regarding the aspects of relevance and the ability to produce tangible outputs in the form of books. These findings indicate that PPjBL is effective and relevant as a project-based training model focused on publication-oriented outputs. This study contributes to the development of a professional teacher training model that not only enhances competencies but also produces tangible outcomes that can be utilized within the educational community.
