Abstract

Kratom leaves (Mitragyna speciosa) are traditionally used as a natural remedy and are known to contain various secondary metabolites with antioxidant potential. This study aimed to activate the antioxidant activity of the aqueous fraction of kratom leaves in vitro. Kratom leaves were extracted using methanol, then liquid-liquid fractionation was performed to obtain the air fraction. Phytochemical screening was performed qualitatively, while antioxidant activity was evaluated using the DPPH, ABTS, and FRAP methods. The phytochemical screening results showed that the air fraction contained alkaloids, phenolic compounds, tannins, quinones, saponins, and steroids/terpenoids, but no flavonoids were detected. Antioxidant activity tests showed that the air fraction exhibited strong antioxidant activity in the DPPH and ABTS methods, with IC₅₀ values of 66.69 ppm and 79.99 ppm, respectively, while the FRAP method showed moderate activity with an IC₅₀ value of 210.88 ppm. The difference in activity between the methods indicates that the air fraction is more effective as a free radical scavenger than as a reducing agent. Based on these results, the air fraction of kratom leaves has potential as a natural antioxidant source. However, further research is needed to identify specific active compounds and to assess biological activity in vivo.

Abstract

Kesehatan menjadi fondasi penting bagi anak untuk merespons tantangan berbagai penyakit di era ini. Anak perlu distimulasi sedini mungkin untuk membangun karakter peduli kesehatan diri sendiri dan lingkungan. Meskipun saat ini informasi mudah diakses, kemampuan anak dalam menyaring informasi masih kurang sehingga perlu edukasi secara langsung. Kegiatan ini bertujuan untuk meningkatkan pemahaman pelajar SDN Akar Bagantung, Kabupaten Banjar, Kalimantan Selatan terkait perilaku hidup bersih dan sehat (PHBS) serta kefarmasian. Sebanyak 32 pelajar menjadi responden. Teknik edukasi menggunakan pembelajaran aktif yakni ceramah interaktif, video pembelajaran, dan simulasi. Tingkat pengetahuan siswa diukur menggunakan kuesioner sebelum (pretest) dan setelah pembelajaran (posttest). Hasil evaluasi menunjukkan sebanyak 68,75% siswa SDN Akar Bagantung menunjukkan peningkatan pengetahuan terkait PHBS dan kefarmasian. Nilai rata-rata gabungan pelajar setelah diberi edukasi adalah 95,31. Edukasi menggunakan pembelajaran aktif efektif dalam meningkatkan pengetahuan pelajar SDN Akar Bagantung mengenai perilaku hidup bersih dan sehat serta kefarmasian.
