Abstract

Excessive exposure to ultraviolet (UV) radiation can cause various adverse effects on the skin, including erythema, premature skin aging, and an increased risk of skin cancer. One of the most effective preventive measures is the proper use of sunscreen selected according to its Sun Protection Factor (SPF) value and individual skin characteristics. However, adolescents' knowledge regarding appropriate sunscreen selection remains limited. This community service program aimed to improve students' knowledge and awareness of selecting appropriate sunscreen based on SPF variation and skin type characteristics. The program employed a participatory educational approach through health education sessions, interactive discussions, demonstrations, and skin condition assessments using a skin analyzer. The activity was conducted at Wirahusada Health Vocational High School, Medan, involving 20 students as participants. The educational materials covered UV radiation, skin types, SPF classification, sunscreen types, and the correct application of sunscreen. Skin condition assessments were performed to determine participants' skin moisture levels as the basis for providing appropriate sunscreen recommendations. The assessment results revealed that 11 participants (55.5%) had normal skin moisture, 7 participants (35.0%) had dry skin, and 2 participants (10.0%) had moist skin. Throughout the program, participants demonstrated high enthusiasm and active engagement during the educational sessions and discussions. The integration of health education with skin condition assessment effectively enhanced participants' understanding of selecting sunscreen according to their individual skin characteristics. Overall, this community service program successfully improved students' knowledge and awareness regarding the appropriate use of sunscreen as an essential strategy for protecting skin health from the harmful effects of ultraviolet radiation.

Abstract

Diabetes mellitus is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin secretion or action. The use of synthetic antidiabetic drugs has a variety of side effects, so the search for alternatives from natural ingredients is constantly being carried out. Yakon leaves (Smallanthus sonchifolius) are known to contain flavonoids such as quercetin which have antidiabetic activity through antioxidant mechanisms and inhibition of glucose-decomposing enzymes. To determine the effectiveness of yakon leaf ethanol extract (EEDY) in lowering blood glucose levels (KGD) in male rats of the Wistar strain induced by nicotinamide and streptozotocin, and to compare it with the positive control of glibenclamide. The experimental study used 25 mice divided into 5 groups: negative control (Na-CMC), positive control (glycenchalamide 0.45 mg/kgBB). and three treatment groups with EEDY doses of 100, 200, and 400 mg/kgBB. Induction of diabetes is carried out with streptozotocin and nicotinamide. KGD was measured before and after treatment and was performed on days 4, 8, 12, 16, 20, 24, and 28. The administration of EEDY showed a significant reduction in KGD (p<0.05) compared to negative controls. The dose of 400 mg/kgBB provides the greatest decreasing effect, approaching the effectiveness of glibenclamide. Statistical analysis showed that there was a significant difference between the negative control group and the treatment.
