Abstract

Penelitian ini bertujuan untuk membuat Lembar Kerja Siswa matematika dengan pendekatan Brain Based Learning yang valid, praktis, dan efektif untuk memfasilitasi kemampuan pemahaman konsep matematis siswa pada materi matriks. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Penelitian dilakukan di SMA Negeri 12 Pekanbaru dengan subjek penelitian yaitu siswa SMA Negeri 12 Pekanbaru. Sampel penelitian adalah kelas XI IPS 6 sebagai kelas eksperimen dan kelas XI IPS 2 sebagai kelas kontrol. Objek penelitian adalah lembar kerja siswa matematika dengan pendekatan Brain Based Learning. Instrumen pengumpulan data berupa angket dan soal tes. Data yang diperoleh dianalisis dengan teknik analisis data kualitatif dan kuantitatif. Hasil penelitian menunjukkan kualitas lembar kerja siswa dengan pendekatan Brain Based Learning yang dikembangkan tergolong dalam kategori sangat valid (89,02%) dan sangat praktis untuk kelompok kecil (88,24%) dan untuk kelompok besar (87,20%). Sedangkan berdasarkan hasil uji inferensial diperoleh thitung sebesar 4,47 dengan  dan taraf signifikan 5% atau 0,05 sehingga Ha diterima dan H0 ditolak. Artinya terdapat perbedaan hasil tes kemampuan pemahaman konsep matematis antara siswa kelas eksperimen dengan nilai rata-rata postes 86,93 dan siswa kelas kontrol dengan nilai rata-rata postes 77,5. Hal tersebut menunjukkan bahwa LKS matematika dengan pendekatan Brain Based Learning ini telah valid, praktis, efektif dan memfasilitasi kemampuan pemahaman konsep matematis siswa pada materi matriks

Abstract

Public investment is one of the main instruments of fiscal policy in encouraging economic growth in developing countries. However, its effectiveness often shows results that vary between countries. This study aims to analyze the role of public investment in economic growth by emphasizing the aspects of investment amount, management efficiency, and expenditure composition. The approach used is qualitative descriptive by utilizing secondary data from several developing countries. The results of the analysis show that countries with higher levels of public investment tend to have better economic growth, although the relationship is not linear. Investment management efficiency has proven to be a key factor that determines success, where countries with higher levels of efficiency are able to produce more optimal growth. In addition, the composition of investment also plays an important role, especially the allocation in the infrastructure sector which correlates with an increase in economic performance. These findings confirm that the success of public investment is not only determined by the size of the budget, but also by the quality of management and the accuracy of allocation. Therefore, fiscal policies in developing countries need to be focused on improving the efficiency and quality of public spending to achieve sustainable economic growth.
