Abstract

Penelitian ini bertujuan untuk memperoleh data latar belakang pendidikan orangtua dan data prestasi belajar siswa untuk mengetahui hubungan latar belakang pendidikan orangtua terhadap prestasi belajar siswa pada masa pandemi  Covid-19 di SMP N 1 Ronggurnihuta. Analisis yang digunakan dalam penelitian ini adalah analisis statistik, bersifat kuantitatif dengan menggunakan analisis data yang berupa angka-angka yang akan diolah. Kegiatan memperoleh data dalam penelitian  ini adalah menggunakan intstrumen pengumpulan data dengan metode dokumentasi yang terkait dalam penelitian. Data yang dikumpulkan berupa data pendidikan orang tua dan prestasi belajar siswa pada masa pandemic Covid-19,kemudian dilakukan pengujian hipotesis dengan uji korelasi dalam mencari korelasi penelitian.Hasil Penelitian yang dilakukan memperoleh korelasi dimana  rxy atau rhitung sebesar 0,65 %  kemudian di interpretasikan kedalam tabel dengan jumlah sampel 23, pada taraf 5 % diperoleh r tabel sebesar 0,396, menunjukkan berada pada koefisien korelasi antara 0,600 sampai dengan 0,800 dengan interpretasi kuat dan tinggi.

Abstract

econdary metabolites are bioactive plant constituents that contribute to antioxidant, anti-inflammatory, and anti-microbial activities, making them valuable for functional food and nutraceuticals applications. This study aimed to characterize the secondary metabolites present in powdered Moringa oleifera leaves, red galangal (Alpinia purpurata (Vieill) K. Schum) rhizomes, and their combination. The 85:15 ratio used in the mixed powder was selected based on preliminary material composition considerations. Metabolite identification was conducted using Ultra High Performance Liquid Chromatography Tandem High Resolution Mass Spectrometry (UHPLC-HRMS). Data processing and compound annotation were performed using ChemSpider and mzCloud. A total of 21 metabolites were identified in moringa leaf powder, 16 compounds in red galangal rhizome, and 17 compounds in the combined preparation. Flavonoid were the dominant class in moringa leaves with quercitrin, 4-aminobenzoid acids, and pheophorbide A as the most abundant constituents. In contrast, phenolic compounds, particularly benzoic derivatives were predominant in red galangal, where menadiol, abietin, and sweroside were the major metabolites. The combined formulation retained key constituents from both plants, including cinnamaldehyde, 4-aminobenzoic acid, and pheophorbide A, and additionally showed an increased level of nictoflorin. These findings provide preliminary compositional evidence demostrating the distinct and complementary phytochemical profiles of moringa leaves and red galangal rhizomes. This information may guide future studies into potential functional food or nutraceutical formulations for further validation through bioactivity, bioavailability, and interaction studies.
