Abstract

Free radicals due to UV exposure, pollution, and the environment damage the skin and accelerate premature aging, so natural antioxidants are needed. This study aims to formulate and evaluate antioxidant body lotion from ethanol extract of yacon leaves (Smallanthus sonchifolius). Semi-quantitative laboratory experimental research used old yacon leaves from Wonosobo as a purposive sample (1,897 g of dried simplicia). Instruments include a UV-Vis spectrophotometer for DPPH (515 nm) test, a Brookfield viscometer, and a pH meter. Data analysis used IC₅₀ regression and physical quality standards (SNI). The results showed that the IC₅₀ of the extract was 28.08 ppm (very strong, <50 ppm), positive phytochemical screening (phenolics, flavonoids), and all lotion formulas (F0-F3: 0-10% extract) met physical standards (pH 4.6-6.2, viscosity 2,187-9,230 cps, O/W emulsion). Formula F1 (2.5%) was optimal overall. The conclusion is that yacon leaf extract has strong potential for the development of a stable body lotion.

Abstract

Hypertension is the most common non-communicable disease in Indonesia with a prevalence of 34.1% in adults aged 18 years and above, with the elderly at high risk due to physiological changes such as decreased kidney function and arterial stiffness. This study aims to identify predictors of antihypertensive drug (ADH) therapy failure and dominant factors in elderly patients at the Sangkrah Surakarta Community Health Center. A quantitative analytical observational study with a cross-sectional design involved 96 elderly respondents (≥60 years) with ADH therapy for at least 3 months, selected the Lemeshow formula and total sampling. Medical record data and questionnaires covering demographics, knowledge, adherence (MMAS-8), lifestyle, were analyzed univariately, bivariately (Chi-Square), multivariate (logistic regression) using SPSS. The results showed 72.9% were male, 71.9% had good knowledge, 80.2% were compliant; Age (p=0.629), gender (p=0.622), and education (p=0.559) were not significant, but knowledge significantly influenced adherence (p=0.011). Low knowledge was the main predictor of therapy failure (BP ≥140/90 mmHg). Intensive education is recommended to improve adherence.
