Abstract

Regularly monitoring uric acid levels is essential for preventing and managing gout, where excess uric acid accumulates in joints and causes pain and swelling. Traditionally, invasive blood sample methods are used for this measurement, which can be uncomfortable and increase medical waste. This community service project, organized by the Physics Department of Universitas Islam Negeri Walisongo Semarang in collaboration with the Ngabdi Neliteni Ngabekti (N3) community organization, compares invasive and non-invasive approaches for uric acid level assessment among residents in Karonsih, Semarang. A newly developed non-invasive device was evaluated alongside standard invasive methods based on participant comfort, accuracy, and feedback. Results indicate that, although the non-invasive device showed a mean error rate of 40.52%, it was preferred for its comfort and non-invasive nature. These findings highlight the potential of non-invasive technology in community health monitoring and underline the importance of regular health check-ups facilitated by collaborations between community organizations, educational institutions, and government bodies.

Abstract

This community service program implemented a science play activities mentoring initiative at Himawari Early Childhood Education Center (TPA-KB-TK Himawari) in Semarang, Indonesia. The program aimed to introduce basic science concepts to young children through enjoyable play-based activities while providing parental education on supporting science learning at home. The intervention involved 30 participants including children, parents, and educators. The program utilized simple, safe materials for hands-on experiments such as color mixing, light refraction with CDs, and creating mini lava lamps. Results demonstrated high engagement from children and positive responses from parents regarding the importance of early science introduction. The initiative successfully bridged the gap between theoretical knowledge and practical application in early childhood science education while strengthening university-community partnerships. This program contributes to community development by enhancing educational quality and promoting scientific literacy from an early age.

Abstract

This community service activity aimed to enhance students' academic competency and preparedness for the National Science Olympiad (OSN) 2023 in Mathematics and Natural Sciences at elementary and junior high school levels. The program, organized by the Physics Department of Universitas Islam Negeri Walisongo Semarang in collaboration with the Association of Madrasah Science Enthusiasts (Perkumpulan Pegiat Sains Madrasah), was conducted online via Zoom Meeting. The training covered eight comprehensive sessions including Kinematics and Mechanics, Forces, Rotational Dynamics, Oscillations and Waves, Electricity and Magnetism, Solar System, Optics, and Temperature and Heat, along with two simulation sessions. Despite challenges such as network connectivity issues and varying participant readiness levels, the program successfully provided intensive coaching to OSN participants and their supervising teachers from elementary (SD/MI) and junior high school (SMP/MTs) levels. This initiative demonstrates the importance of systematic academic preparation and highlights the role of higher education institutions in supporting K-12 education excellence through collaborative mentoring programs.

Abstract

Vital signs, namely oxygen saturation (SpO₂), heart rate (HR), and body temperature, are fundamental physiological indicators of overall health status. Their periodic monitoring in the general population supports early identification of oxygenation disorders, cardiovascular conditions, and infection or inflammation before these progress to more serious conditions. This research-based community service activity carried out a free vital-sign screening for residents of RT 005 RW IV, Kelurahan Gondoriyo, Ngaliyan, Semarang, on 28 June 2026, using a pulse oximeter for SpO₂ and HR and a non-contact infrared thermometer for body temperature. Twenty community members were screened, with duplicate SpO₂ and HR measurements taken for each participant; the second reading of each was used as the analysis reference after the first-attempt readings were assessed as reflecting an initial probe signal-stabilization phase. Results showed a mean SpO₂ of 96.8% (range 79–100%), with 90% (18 of 20 participants) within the normal range (≥95%) and one participant showing severe hypoxemia (79%) requiring urgent referral. Mean HR was 59.2 beats per minute (range 35–100), with only 35% (7 of 20) within the standard resting range of 60–100 bpm; two participants showed severe bradycardia (35 and 37 bpm) requiring immediate electrocardiographic evaluation. Mean body temperature was 35.65°C (range 34.5–36.3°C), a pattern consistent with the known sensitivity of non-contact infrared thermometry to outdoor ambient conditions. The activity produced individualized referral recommendations for participants with critical findings and supports periodic, six-monthly community vital-sign screening, particularly for residents above 40 years of age.
