Abstract

Penelitian ini mengkaji efektivitas implementasi Kurikulum Merdeka terhadap prestasi belajar siswa di SMAN 1 Samaturu. Pendekatan kualitatif dengan metode wawancara, observasi, dan analisis data akademik digunakan untuk mengidentifikasi dampak penerapan kurikulum yang berpusat pada peserta didik dan berbasis proyek. Hasil penelitian menunjukkan bahwa Kurikulum Merdeka berhasil meningkatkan motivasi belajar, keterampilan berpikir kritis, kreativitas, dan hasil akademik siswa, khususnya pada mata pelajaran eksplorasi dan penelitian. Peran guru sebagai fasilitator dan dukungan orang tua menjadi faktor penting dalam keberhasilan implementasi. Meski demikian, adaptasi siswa dan guru terhadap sistem baru serta ketersediaan bahan ajar menjadi tantangan yang perlu diatasi. Sekolah berupaya melakukan pelatihan guru dan sosialisasi kepada orang tua untuk memaksimalkan efektivitas kurikulum. Temuan ini memberikan gambaran penting bagi pengembangan kurikulum dan strategi pembelajaran inovatif dalam menghadapi tuntutan pendidikan abad ke-21.

Abstract

This study aims to analyze the implementation of the principal's academic supervision in improving the performance of Islamic Religious Education (PAI) teachers at MTs Al Mawaddah Warrahmah Kolaka. The research method used was descriptive qualitative with academic supervision approach. Data collection was conducted through interviews, observations, and documentation with the principal and PAI teachers as the main subjects of the research. The results showed that the academic supervision conducted by the principal has been running well, using various techniques such as clinical supervision, class visits, class observations, teacher meetings, evaluations, and follow-ups. Clinical supervision is the main method in providing guidance to teachers, while classroom visits and observations help in assessing teaching effectiveness. Evaluation is conducted periodically to assess the impact of supervision on improving teachers' professionalism. Follow-up in the form of individual coaching and additional training is also provided to teachers who still have shortcomings. The results of this study are in line with the theory of academic supervision which emphasizes the importance of guidance and monitoring in improving the quality of learning. Therefore, the implementation of systematic and sustainable academic supervision needs to be continuously developed to support the improvement of the quality of education in madrasah.

Abstract

Penelitian bertujuan mengevaluasi efektivitas penggunaan Polyurethane (PU) grouting injeksi dalam memperbaiki beton retak melalui uji laboratorium dan aplikasi lapangan. Tujuan utama penelitian adalah menilai pengaruh PU dengan variasi konsentrasi 25%, 50%, dan 75% terhadap kuat tekan beton K-250 serta daya tahan terhadap rembesan air. Hasil uji laboratorium menunjukkan bahwa PU 50% paling efektif mengurangi rembesan air dengan kadar 1,87%, dibanding PU 25% (2,54%) dan PU 75% (3,20%). Namun, semua variasi PU tidak meningkatkan kuat tekan beton, yakni berkisar antara 4,33–4,58 MPa, lebih rendah dari beton normal K-250. Studi lapangan pada pelat lantai II Fakultas Teknik Universitas Andi Djemma menunjukkan metode injeksi PU spoid efektif menutup retakan <2 mm dan lebih praktis serta ekonomis dibanding metode tekanan tinggi. Kesimpulannya, PU grouting cocok untuk perbaikan beton non-struktural yang fokus pada pengurangan rembesan air, tetapi tidak direkomendasikan untuk meningkatkan kekuatan tekan. This study evaluated the effectiveness of Polyurethane (PU) injection grouting in repairing cracked concrete through laboratory tests and field applications. The main objective of the study was to assess the effect of PU with various concentrations of 25%, 50%, and 75% on the compressive strength of K-250 concrete and its resistance to water seepage. Laboratory test results showed that 50% PU was the most effective in reducing water seepage with a content of 1.87%, compared to 25% PU (2.54%) and 75% PU (3.20%). However, all PU variations did not increase the compressive strength of concrete, which ranged from 4.33–4.58 MPa, lower than normal K-250 concrete. Field studies on the second floor slab of the Faculty of Engineering, Andi Djemma University showed that the PU spoid injection method was effective in closing cracks <2 mm and was more practical and economical than the high-pressure method. In conclusion, PU grouting is suitable for non-structural concrete repairs that focus on reducing water seepage, but is not recommended for increasing compressive strength.
