Abstract

Maintaining health is an obligation and an important investment in order to live a productive and meaningful life. To maintaining and improving health, various health methods and products have attracted public attention. One product that is getting more attention is rubbing oil. The aim of this activity is to provide knowledge and skills to the community of Lok Bahu Region in producing rubbing oil independently. An educational approach is used to explain the ingredients, manufacturing process, and benefits of using the rubbing oil. The results of this service activity show a significant increase in public knowledge about the health benefits of using rubbing oil. Apart from that, service participants also demonstrated increased skills in making rubbing oil which can be implemented independently in the household environment. Evaluation of this activity shows that this program has succeeded in increasing public awareness of the use of natural ingredients for health.

Abstract

Oxidative stress drives many degenerative conditions, motivating the search for safe, plant-based antioxidants. Sago (Metroxylon sagu Rottb.) leaf is comparatively underexplored. This study evaluated its antioxidant activity and related it to phenolic and flavonoid contents. A 96% ethanolic leaf extract was assayed for radical-scavenging activity by DPPH using ascorbic acid as the positive control; IC50 values were obtained from linear regression of % inhibition versus concentration (2.5–10 ppm). Composition was profiled by total phenolic content (TPC; Folin–Ciocalteu, expressed as mg gallic acid equivalents per g, mg GAE/g) and total flavonoid content (TFC; AlCl3 colorimetry, expressed as mg quercetin equivalents per g, mg QE/g). The extract showed very strong DPPH activity (IC50 = 11.873 ± 0.025 µg/mL), while ascorbic acid yielded 3.166 ± 0.025 µg/mL; both fall within the <50 µg/mL category. The extract contained TPC = 1.61% w/w (~16.1 mg GAE/g) and TFC = 3.05% w/w (reported on the quercetin-equivalent scale). These indices are consistent with the low IC50 and support a phenolic-driven antioxidant profile. Metroxylon sagu leaf extract exhibits very strong radical-scavenging activity, supported by appreciable levels of phenolics and flavonoids, which identify M. sagu leaves as a promising natural antioxidant source. The findings provide a concise quantitative basis for follow-up work focused on targeted phenolic/flavonoid profiling, as well as broader antioxidant evaluations.
