Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh pengelolaan kelas terhadap prestasi belajar Negeri terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019. Jumlah populasi dalam penelitian ini adalah 102 orang dimana sampel penelitian yang diambil sebanyak 34 orang. Skor rata-rata prestasi belajar Negeri terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019 adalah 80,18. Untuk mengetahui besarnya korelasi antara pengelolan kelas terhadap prestasi belajar Negeri terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019 dihitung dengan mengunakan rumus korelasi product moment, hipotesis diuji dengan signifikan dari korelasi statistika student atau uji -t pada taraf signifikan 0,05 dan untuk mengetahui besarnya kontribusi antara variabel X dan variabel Y dihitung dengan rumus determinasi. Besarnya koefisien korelasi pengelolaan kelas terhadap prestasi belajar Negeri terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019 yaitu r = 0,71. Dari hasil pengujian hipotesis dengan uji t, diperoleh t hitung = 5,74 pada taraf nyata α = 0,05 dan dk = 32 diperoleh t-tabel = 1,70. Jadi harga t-hitung lebih besar daripada harga t-tabel (t hitung = 5,74 > t-tabel = 1,70), maka Ho ditolak dan Ha diterima, artinya ada pengaruh yang signifikan antara pengelolaan kelas terhadap prestasi belajar Negeri Terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019. Besarnya kontribusi/pengelolaan kelas terhadap prestasi belajar NEGERI terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019 adalah sebesar 50,41%. artinya prestasi belajar Negeri Terpadu siswa sebesar 50,41%. Dari hasil penelitian ini disimpulkan ada pengaruh pengelolaan kelas terhadap prestasi belajar Negeri terpadu siswa kelas VII SMP Negeri 1 Bandar Masilam Tahun Pelajaran 2018/2019 .

Abstract

Hypertension in the elderly increases the risk of cardiovascular disease and reduces quality of life. In addition to pharmacological therapy, garlic (Allium sativum) as a complementary herbal therapy has the potential to lower blood pressure through its allicin and S-allylcysteine ​​content, which act as vasodilators, antioxidants, and angiotensin-converting enzyme inhibitors. This study aims to systematically review the effectiveness of garlic therapy in lowering blood pressure in the elderly with hypertension. The research method used was a literature review with a narrative-descriptive approach. Articles were searched through PubMed, ScienceDirect, Google Scholar, and Scopus databases for publications from 2020 to 2025. A total of 19 articles that met the inclusion criteria were analyzed, including randomized controlled trial designs, quasi-experimental, and pre-experimental. The variables studied included dosage form, dose, duration of administration, changes in systolic and diastolic blood pressure, and side effects. Results showed that various forms of garlic, such as tea, decoction, capsules, black garlic, and aged garlic extract, consistently lowered systolic blood pressure by 10–30 mmHg and diastolic blood pressure by 5–20 mmHg in older adults with hypertension. Reported side effects were generally mild. It was concluded that garlic is potentially effective and safe as a complementary therapy for hypertension in older adults, although further standardized research is needed.
