Hyperuricemia is a condition of increased uric acid levels in the blood that can develop into various metabolic disorders, including gouty arthritis and kidney disease. Physical activity is known to play an important role in controlling uric acid levels by increasing excretion and inhibiting purine production. This activity uses the Plan-Do-Check-Act (PDCA) approach which includes checking uric acid levels using the Point-of-Care Testing (POCT) method in 91 productive-age individuals, as well as education about the importance of physical activity. The results were obtained directly and presented to the participants along with interpretive explanations and preventive recommendations. The average uric acid levels of the participants were recorded at 3.78 ± 0.60 mg/dL with a range of 2.5 to 5.6 mg/dL. All participants (100%) had uric acid levels within the normal range. Physical activity contributes to the regulation of uric acid levels, so proper education remains important even though the examination results show normal values. Education-based interventions play a role in strengthening primary prevention.

The program follows the Plan-Do-Check-Act (PDCA) approach, encompassing planning for education and screenings, conducting information sessions and cholesterol measurements, evaluating program effectiveness, and implementing follow-up actions for continuous improvement. Education on a healthy lifestyle, which includes a balanced diet, physical activity, and avoidance of alcohol and smoking, plays a vital role in maintaining normal cholesterol levels. Routine screenings are also essential for the early detection of high cholesterol risks. This initiative is expected to promote healthy behaviors and support improved workplace health by raising awareness about the importance of cholesterol prevention in the work environment.

Vitamin D is an essential steroid hormone that plays a role in calcium and phosphorus regulation and has the potential to affect sleep quality. Vitamin D deficiency in the elderly often occurs due to minimal exposure to sunlight and age-related physiological changes, which contribute to the high incidence of sleep disorders, including insomnia. This community service activity aims to screen vitamin D levels in the elderly as a cause of insomnia through the Plan-Do-Check-Act (PDCA) approach. The activity was carried out at Panti Bina Bhakti, South Tangerang, involving 93 elderly participants aged > 65 years. The results showed that the average vitamin D levels among the age groups 61-70 years, 71-80 years, 81-90 years, and 91-100 years were 7.6 mg/dl, 7.2 mg/dl, 7.6 mg/dl, and 13.9 mg/dl, respectively. Interventions through vitamin D supplementation, sunlight exposure, and education in the form of sleep hygiene are effective in improving the health and sleep quality of the elderly.

Dermatoporosis is a chronic skin fragility syndrome common in the elderly, characterized by thinning of the skin that increases the risk of injury, bruising, and delayed wound healing. Chronic hyperglycemia and poor glycemic control have been reported to be associated with an increased risk of dermatoporosis. This community service activity aims to screen blood sugar levels, HbA1c, and dermatoporosis and educate the elderly using the Plan-Do-Check-Act (PDCA) method at Panti Bina Bhakti, South Tangerang. This activity involved 93 elderly participants aged >65 years. Meanwhile, based on the results of the HbA1C examination, 52 people had moderate glycemic control and 24 people had poor glycemic control. The results of the dermatoporosis examination have not been included. Early intervention through education and monitoring of blood sugar levels can reduce the risk of dermatoporosis, improve the health of the elderly's skin, and reduce the burden of health care.
