Abstract

Tujuan penelitian ini untuk mengetahui keefektifan model pembelajaran Group Investigation (GI) berbantu media daun terhadap pemahaman konsep peserta didik pada materi bentuk aljabar. Jenis penelitian yang digunakan adalah kuantitatif eksperimen dengan desain penelitian pretest posttest control group design untuk variable kemampuan pemahaman konsep. Pengambilan sampel menggunakan teknik cluster random sampling. Teknik pengumpulan data dalam penelitian ini menggunakan metode tes, yaitu pretest dan posttest. Hasil analisis data diperoleh rata-rata kemampuan pemahaman konsep peserta didik kelas eksperimen dan kelas kontrol . Hasil uji hipotesis terhadap kemapuan pemahaman konsep peserta didik dengan taraf signifikan 5% diperoleh dan . Karena maka rata-rata kemampuan pemahaman konsep kelas eksperimen lebih baik daripada kelas kontrol. Analisis uji ketuntasan belajar menggunakan uji-t satu sampel diperoleh dan . Karena maka dapat disimpulkan kelas eksperiment secara klasikal dapat dikatakan tuntas. Jadi model pembelajaran Group Investigation (GI) berbantu media daun efektif terhadap kemampuan pemahaman konsep pada materi bentuk aljabar.

Abstract

The Rp 300 trillion tin trade mega-corruption case is one of the largest corruption scandals in the history of Indonesian natural resource management. This study aims to analyze violations of Pancasila principles and ethical governance in the tin trade mega-corruption case, and to identify threats to Indonesian natural resource management. The study uses a qualitative approach with descriptive methods. Data were collected through documentary studies of law enforcement reports, government documents, media reports, and related literature. Data analysis was conducted thematically within the theoretical framework of Pancasila, good governance, and public ethics. The findings indicate that this case violates all of Pancasila's tenets, particularly the second (Just and Civilized Humanity) and fifth (Social Justice for All Indonesian People). There were violations of governance principles including transparency, accountability, participation, the rule of law, and effectiveness. The modus operandi involved collusion between business actors, state officials, and law enforcement officers. The mega-allegations reflect a systemic failure in natural resource management that contradicts the constitutional mandate and Pancasila values. Structural reforms are needed in mining governance, enforcement of the integrity of the apparatus, and public participation in supervision.
