Abstract

Kesehatan masyarakat sangat penting dalam membangun desa. Salah satu cara nyata untuk melakukannya adalah melalui KKN Tematik Kesehatan yang langsung mengunjungi warga. Kegiatan ini diadakan di Desa Sukapura, Kecamatan Kertasari, Kabupaten Bandung. Fokus utamanya adalah meningkatkan kesadaran warga mengenai penyakit Tuberkulosis (TBC), stunting, serta penyakit tidak menular seperti hipertensi dan diabetes. Metode yang digunakan meliputi penyuluhan kesehatan dengan uji pengetahuan awal dan akhir, pemeriksaan kesehatan gratis, serta kunjungan rumah untuk memberikan edukasi tambahan kepada pasien TBC. Hasil menunjukkan peningkatan pemahaman masyarakat mengenai penyebab, cara penyebaran, dan pencegahan TBC serta stunting. Hal ini terlihat dari peningkatan skor pengetahuan setelah mengikuti penyuluhan. Selain itu, dari pemeriksaan kesehatan diketahui sebagian besar penduduk mengalami tekanan darah tinggi dan beberapa dalam kondisi pradiabetes hingga diabetes, menyiratkan perlunya edukasi tentang gaya hidup sehat. Kegiatan ini juga membuka ruang komunikasi antara masyarakat, mahasiswa, dan tenaga kesehatan serta menekankan pentingnya pendekatan promosi dan pencegahan yang berkelanjutan. Dengan demikian, program ini dianggap berhasil dalam membangun kesadaran awal, namun diperlukan intervensi jangka panjang agar perubahan perilaku dapat berlangsung terus menerus.

Abstract

This study aims to analyze the Indonesian capital market's reaction to the political demonstrations on August 29, 2025, as a form of non-electoral political risk that could potentially impact stock market performance. In the context of increasing financial market sensitivity to socio-political uncertainty, this study uses a quantitative explanatory approach with an event study method to test for abnormal returns (AR) and cumulative abnormal returns (CAR) on the Indonesian Stock Exchange (IDX) during the observation period. Secondary data were obtained from the daily closing prices of the IDX with an estimation window from July 1 to August 22, 2025, and a seven-day event window surrounding the event. The analysis results show that although no significant abnormal returns were found on the day of the event, there was a statistically significant negative cumulative abnormal return during the observation period, indicating that the political demonstrations exerted accumulative pressure on the stock market. These findings indicate that the Indonesian capital market reacts negatively to non-electoral political events, with an indirect and cumulative adjustment pattern, reflecting the characteristics of an emerging market with semi-strong efficiency. This research contributes to expanding the literature on political risk in emerging markets and provides practical implications for investors and policymakers to strengthen risk mitigation strategies and maintain market stability amidst domestic political uncertainty.

Abstract

Abstract Micro and ultra-micro enterprises have an important role in the community’s economy; however, they still face limitations in maintaining systematic financial transaction records. This activity aimed to analyze the effectiveness of a seminar and training program on single-entry financial transaction recording for micro and ultra-micro entrepreneurs through the Impactful Thematic Community Service Program (KKN Tematik Berdampak) of Universitas Al-Ghifari in 2026 in Lampegan Village, Ibun District, Bandung Regency. The activity employed a pre-experimental approach using a one-group pretest-posttest design involving 17 participants. Measurements were conducted across three dimensions: affective, cognitive, and psychomotor. Data were analyzed using descriptive statistics, the Shapiro-Wilk test, the Wilcoxon Signed Rank Test, effect size, and N-Gain Score. The results showed an increase in the mean affective score from 3.59 to 7.18, cognitive score from 3.18 to 6.59, and psychomotor score from 2.94 to 5.47. The Wilcoxon test indicated significant differences across all dimensions (p ≤ 0.001), with a large effect size (r = 0.835–0.900). The N-Gain results indicated high effectiveness in the affective and cognitive dimensions and moderate effectiveness in the psychomotor dimension and overall score. Thus, the seminar and training effectively improved participants’ attitudes, knowledge, and skills in single-entry financial transaction recording.
