The rupiah plays a vital role as a symbol of national identity and sovereignty, but awareness among rural communities about its function and importance is often limited. In Kutalimbaru Village, the main challenges identified are low monetary literacy, which results in physical damage to money and a lack of awareness about counterfeit money. Through the Real Work Lecture (KKN) program, community service efforts were carried out with the aim of internalizing the values of “Love, Pride, Understanding (CBP) of the Rupiah.” The approach used was community-based education through interactive workshops and practical demonstrations on money care techniques and an introduction to the security features of the Rupiah. Findings in the field show a transformation in the community's attitude; from being indifferent to being more careful in handling paper money and better understanding the role of the Rupiah in economic stability. This program has succeeded in increasing the financial literacy of citizens while strengthening the spirit of nationalism through appreciation of the national currency.

This study aims to analyze the role of local Micro, Small, and Medium Enterprises (MSMEs) in utilizing lemongrass (Cymbopogon citratus) as the main ingredient for mosquito repellent products and its contribution to improving the economy of the community in Timbang Jaya Village. Lemongrass contains essential oils that function as a natural insect repellent, making it a potential raw material for value-added products such as mosquito repellent sprays, aromatherapy candles, and herbal lotions. This research employed a descriptive qualitative method with data collected through interviews, observations, and literature studies. The findings indicate that local MSMEs play a significant role in the production process, product innovation, and marketing of lemongrass-based products. Besides generating additional income, this development also creates new job opportunities and supports the village’s economic independence. However, several challenges remain, including limited capital, lack of processing technology skills, and competition with chemical-based products. The recommended solutions include capacity building through training and mentoring, better access to funding, and strengthening digital marketing strategies. Therefore, the development of mosquito repellent products from lemongrass by MSMEs not only contributes to the community’s economic growth but also provides an environmentally friendly alternative beneficial for public health.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

Financial literacy is a fundamental skill that should be introduced from an early age to shape wise financial behavior. Elementary school students need to understand basic financial concepts to recognize the value of money, distinguish between needs and wants, and develop saving habits. However, many children still lack adequate financial literacy. This activity aims to improve financial literacy among elementary school students through a saving habituation strategy at SD Negeri 040530 Bunuraya, Bunuraya Village, Tigapanah District, Karo Regency, North Sumatra Province, Indonesia. The methods used included observation, teacher interviews, financial literacy socialization, and hands-on assistance in saving activities. The strategies implemented involved simple financial education, pocket money management simulations, creating piggy banks, and conducting regular saving programs at school. The results showed an improvement in students’ understanding of money functions, the importance of saving, and positive changes in financial behavior. Students became more accustomed to setting aside their pocket money and demonstrated more frugal and responsible attitudes. This activity indicates that consistent and structured saving habituation can be an effective strategy for improving children’s financial literacy from an early age.

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.

This study examines the role of KKN students in supporting the economic development of Micro, Small, and Medium Enterprises (MSMEs) through bazaar activities in Selayang Village. The bazaar programs facilitated by KKN students proved effective in improving product marketing, expanding business networks, increasing public awareness of local products, and ultimately raising the income of MSME actors. In addition to their economic impact, the bazaars functioned as promotional platforms and spaces for social interaction that strengthened relationships between community members and local entrepreneurs. Despite facing internal challenges such as limited funding, inadequate human resources, and a lack of product innovation, the initiative demonstrated positive outcomes. Collaboration among KKN students, local government, and the community is considered essential to ensure the sustainability of such empowerment programs. Overall, the findings indicate that bazaar activities represent an effective strategy for rural economic empowerment, contributing to the long-term competitiveness and growth of MSMEs while fostering community participation and local economic resilience.

The rapid rise of short-form social media platforms, particularly TikTok, among adolescents has raised concerns regarding excessive use and potential behavioral addiction that may negatively affect mental health and academic functioning. This community engagement program aimed to screen the risk of TikTok addiction among secondary school students in West Jakarta and provide education on healthy digital practices. The program was conducted at one private school in Jelambar, involving 306 students aged 11–18 years. Screening was performed using the TikTok Addiction Scale (TTAS) followed by digital literacy education. A Plan–Do–Check–Action (PDCA) framework was applied to ensure systematic implementation. The mean TTAS score was 39.97 ± 14.24 (range 20–84), indicating diverse levels of TikTok engagement. Female students demonstrated higher scores and wider distribution, suggesting greater vulnerability to excessive social media use. Digital hygiene and screen-time management education enhanced students’ awareness regarding social media addiction risks and appropriate preventive strategies. This program demonstrated the feasibility and effectiveness of TTAS-based screening for early identification of TikTok addiction risk. It highlighted the importance of integrating digital health promotion into school-based mental health programs to support adolescent well-being.

Chronic kidney disease (CKD) is a growing global health concern that frequently remains undiagnosed until advanced stages. Early detection through simple laboratory screening is essential to prevent disease progression and associated cardiometabolic complications. This community service program aimed to assess kidney function using serum creatinine and estimated glomerular filtration rate (eGFR), while increasing public awareness regarding CKD prevention. A total of 59 participants were included, with a mean age of 39.15 ± 15.39 years (range 16–75 years), predominantly female (74.58%). The mean serum creatinine level was 1.0 ± 0.19 mg/dL, and the mean eGFR was 91.08 ± 20.53 mL/min/1.73 m². Most participants demonstrated normal kidney function (28.8%) or mild decline (21.6%). A progressive reduction in eGFR with increasing age was observed, reflecting the physiological decline in nephron mass and renal perfusion. The program also provided education on kidney-protective practices, including optimal blood pressure control, diabetes management, adequate hydration, and avoidance of nephrotoxic agents. This intervention improved participants’ understanding of CKD risk factors and the importance of regular screening. In conclusion, serum creatinine and eGFR evaluation offer simple, accurate, and practical tools for early CKD detection, supporting promotive–preventive strategies to slow disease progression and enhance quality of life in at-risk populations.
