Knee osteoarthritis (OA) is one of the leading causes of disability among the elderly population. This degenerative joint disease is characterized by progressive damage to the articular cartilage and structural alterations of the knee joint, resulting in pain, reduced mobility, and diminished quality of life. This Community Service Program (PKM) aimed to promote early detection of knee OA through simple radiological screening as a preventive strategy to reduce the risk of musculoskeletal disability. The activity was conducted at Asisi Church, South Jakarta, involving 87 participants aged 54–87 years (mean 70.77 ± 7.32 years). Radiological examination was performed using standard anteroposterior knee X-rays, and results were classified according to the Kellgren–Lawrence grading system. Findings revealed that 98.9% of participants exhibited radiological signs of OA, predominantly grade II (60.9%), followed by grade III (21.8%), grade I (11.5%), and grade IV (4.6%), while only 1.1% showed normal results. Female participants (74.7%) predominated across all OA grades, indicating hormonal and biomechanical influences on disease progression. The mean age increased with OA severity, supporting the degenerative theory that aging leads to decreased chondrocyte function and cartilage elasticity. In addition to screening, participants received education on weight management, muscle strengthening exercises, and injury prevention. The results demonstrate that simple radiological screening is an effective, practical, and cost-efficient community-based approach for early detection of knee OA. Integrating such preventive strategies within primary care systems could significantly reduce the burden of disability among the elderly population.

Significant temperature changes make the body unable to adjust properly, which eventually leads to disease, affects the immune system, and increases the risk of developing viruses and bacteria. Empowerment of family medicinal plants in the cultivation and utilization of TOGA can be a way to overcome these problems, especially in the city of Surabaya. The purpose of this community service is to increase public understanding of the efficacy of TOGA and to create facilities for nature conservation, especially the cultivation of TOGA greenery. The form of community service activities is providing education, giving and planting TOGA, and monitoring TOGA maintenance. The resulting output is increasing public understanding of the efficacy of TOGA and creating facilities for nature conservation, especially cultivating reforestation for special TOGA gardens (Kencur, turmeric, temulawak, and binahong) so that they can help realize preventive and promotional communities in overcoming disease problems that often arise during the transition season.
