Abstract

Perilaku Hidup Bersih dan Sehat (PHBS) merupakan fondasi penting dalam menjaga kualitas kesehatan, terutama di lingkungan padat seperti panti asuhan. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan pemahaman dan kesadaran tentang PHBS bagi anak-anak dan pengurus Panti Asuhan Darul Amanah di Jati Mulyo, Lampung Selatan. Panti ini mengasuh 51 anak dengan rentang usia 3–20 tahun, mayoritas berusia di bawah 12 tahun, dan diasuh oleh lima orang pengurus. Sosialisasi dilaksanakan pada Sabtu, 15 Maret 2025, dengan narasumber Dr. Rahmat Kurniawan, S.Si., dari Program Studi Kimia ITERA. Kegiatan ini diikuti oleh 27 peserta dan diawali dengan pretest, penyampaian materi interaktif, demonstrasi praktik PHBS, serta diakhiri dengan posttest. Hasil evaluasi menunjukkan adanya peningkatan pemahaman peserta dengan rata-rata nilai pretest sebesar 79,62 dan posttest meningkat menjadi 94,81. Kegiatan berjalan lancar dan peserta menunjukkan antusiasme tinggi. Temuan ini mengindikasikan bahwa edukasi PHBS secara langsung dan kontekstual efektif dalam meningkatkan pengetahuan dan membentuk kesadaran perilaku sehat di lingkungan panti. PkM ini diharapkan menjadi awal dari pembiasaan PHBS yang berkelanjutan dan diterapkan dalam kehidupan sehari-hari.

Abstract

Zinc oxide (ZnO) nanoparticles are one of the most widely studied nanoparticles for various applications and other alternatives because of their unique properties. The uniqueness of these properties depends on the technique used to synthesize ZnO nanoparticles. This study aims to synthesize ZnO nanoparticles using tomato crude extract as a capping agent and to analyze the antioxidant activity of ZnO nanoparticles using DPPH and ascorbic acid as standard solutions. The synthesized powder of ZnO nanoparticles was characterized using XRD and SEM. The results obtained for the crystal size of the capping agent and without the capping agent were 20.597 nm and 24.717 nm according to JCPDS No. 00-036-1451. The particle size of ZnO using tomato extract as a capping agent is 43.325 nm which indicates that the particles are in the nanosize range and are spherical in shape. The IC50 yield of ZnO nanoparticles using a capping agent was 133.9623 ppm which indicated that ZnO nanoparticles had moderate antioxidant activity.

Abstract

Indonesia’s rich biodiversity includes Moringa oleifera, widely used in traditional medicine. However, environmental factors such as climate, soil, and agronomic practices can influence the phytochemical composition and bioactivity of its leaves. This study aimed to investigate the phytochemical profile and antioxidant activity of acetone extracts of M. oleifera leaves sourced from South Lampung. Leaves were air-dried, powdered, and extracted via maceration in acetone. Phytochemical screening employed standard reagents (Dragendorff’s and Mayer’s for alkaloids; Mg and HCl for flavonoids; Liebermann–Burchard for steroids and triterpenoids; FeCl₃ for tannins; foam test with 2 N HCl for saponins). Antioxidant capacity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. Phytochemical screening revealed the presence of alkaloids, flavonoids, steroids, triterpenoids, and tannins, while saponins were not detected. In the DPPH assay, percentage inhibition increased with concentratio, yielding an IC₅₀ of approximately 209.4 ppm. This relatively high IC₅₀ indicates weak radical-scavenging activity under the present conditions. The findings provide the first detailed report of phytochemical constituents and DPPH-based antioxidant capacity for acetone extracts of M. oleifera leaves from South Lampung. Although secondary metabolites with known bioactivities were detected, the weak DPPH scavenging suggests that acetone may not optimally extract the most potent antioxidant compounds or that local growth conditions yield lower phenolic/flavonoid concentrations.
