Dengue Hemorrhagic Fever (DHF) remains a major public health problem in Indonesia, particularly in densely populated areas. Control efforts require accurate data and spatial analysis to understand disease distribution patterns. Geographic Information System (GIS) is an effective tool for visualizing case distribution and supporting surveillance and planning of control programs at the primary healthcare level. This study aims to describe the spatial distribution of Dengue cases based on medical record data and produce a geographic distribution map to support Dengue control efforts at the Puskesmas level. This study used a quantitative descriptive design with secondary data from medical records at Karangsari Health Center. The sample consisted of 255 DHF patients in 2025, selected using a total sampling technique. Data were processed through editing, geocoding patient addresses, and spatial analysis using QGIS software.The results showed 255 Dengue  cases in 2025 with fluctuating monthly trends, peaking in April and lowest in December. Case distribution was uneven and tended to cluster. High-risk areas accounted for 15.7%–21.2%, moderate-risk areas 9.8%–15.7%, and low-risk areas 7.1%–9.8%. Megu Cilik Village had the highest proportion of cases, while other villages were categorized as moderate and low risk. This pattern indicates that Dengue incidence is influenced by environmental conditions, vector density, host factors, rainfall, and Aedes aegypti presence. GIS provides clearer spatial visualization, helping identify high-risk areas and supporting targeted public health interventions.

Dengue Hemorrhagic Fever (DHF) remains a significant public health problem in tropical countries, including Indonesia. The presence of Aedes aegypti larvae is an important indicator of dengue transmission risk and is influenced by environmental factors, particularly temperature and humidity. This study aimed to analyze the relationship between temperature and humidity and the presence of mosquito larvae in Meteseh Village, Tembalang District, Semarang City. This analytical observational study employed a cross-sectional design involving 100 households selected through quota sampling. Data were collected through direct observation and measurement of temperature and humidity using a thermo-hygrometer, then analyzed using the Chi-square test. The results showed a significant association between temperature and the presence of mosquito larvae (p=0.000), while humidity was not significantly associated with larvae presence (p>0.05). Temperature was identified as a more influential environmental factor in supporting mosquito larvae existence than humidity in the study area. These findings highlight the importance of environmental-based vector control strategies, particularly through management of microhabitat temperature conditions, to support dengue prevention.

Dengue remains a major vector-borne disease worldwide, and the increasing resistance of Aedes aegypti to synthetic insecticides has encouraged the exploration of environmentally friendly botanical larvicides. This study aimed to systematically evaluate scientific evidence regarding the larvicidal potential of endemic Kalimantan plants against Aedes aegypti and to identify priority candidates for future research. A systematic literature review was conducted following the PRISMA 2020 guidelines. Literature searches were performed across Scopus, PubMed, ScienceDirect, SpringerLink, Web of Science, MDPI, Wiley Online Library, Garuda, SINTA, and Google Scholar for studies published between January 2016 and January 2026. A total of 925 records were identified, and after duplicate removal, screening, and eligibility assessment, 88 studies were included in the final synthesis. The results showed that botanical larvicides rich in alkaloids, flavonoids, terpenoids, phenolics, limonoids, and sulfur compounds demonstrated significant larvicidal activity against Aedes aegypti. However, no direct larvicidal studies were identified for endemic Kalimantan species, including Fibraurea tinctoria, Arcangelisia flava, Dacrydium beccarii, Agathis borneensis, and Scorodocarpus borneensis. These findings highlight substantial evidence gaps and indicate that Kalimantan biodiversity represents a promising source of novel larvicidal agents for sustainable dengue vector control.

The increasing adoption of cloud native microservices has brought about significant improvements in scalability, flexibility, and resilience. However, these advancements also introduce substantial security challenges, particularly in distributed environments where traditional perimeter-based security models prove inadequate. This paper proposes a secure architecture for cloud native microservices that integrates Zero trust Network Access (ZTNA) and multi layered encryption techniques to address these security concerns. The architecture operates on the principle of "never trust, always verify," ensuring that access to resources is strictly controlled and continuously monitored. By incorporating multi layered encryption methods such as RSA and AES, the architecture ensures data protection both in transit and at rest, significantly reducing the risk of data breaches and unauthorized access. Through experimental evaluations, the proposed architecture demonstrated its effectiveness in preventing lateral movement, mitigating data leakage, and resisting common attack vectors such as man-in-the-middle (MITM) attacks and privilege escalation. Additionally, the performance of the system remained optimal, with minimal overhead despite the additional security layers. The architecture's scalability and robust security mechanisms make it a viable solution for real-world microservices environments, where both security and performance are crucial. This paper discusses the potential impact of this secure architecture on the broader field of distributed system security and offers recommendations for future work, including the integration of advanced machine learning techniques for real-time threat detection and automated responses, as well as the adaptation of the architecture for emerging technologies like edge computing and 6G networks.

Dengue Hemorrhagic Fever (DHF) remains a major public health problem in endemic areas, including Olat Rarang Hamlet, Labuhan Sumbawa Village. Effective dengue prevention requires active community involvement supported by entomological surveillance data. This community service activity aimed to enhance community awareness and participation in dengue prevention through the implementation of the 3M Plus Movement integrated with an entomological surveillance approach using the House Index (HI), Container Index (CI), and Breteau Index (BI) indicators. The activity was conducted on December 6, 2025, involving local community members and public health students. The methods included health education, larval surveys in houses and water-holding containers, and community-based mosquito breeding site eradication. The results indicated that houses and containers positive for Aedes larvae were still present, reflecting a moderate risk of dengue transmission. However, the implementation of the 3M Plus Movement improved community knowledge, awareness, and participation in vector control. Integrating the 3M Plus Movement with entomological surveillance is an effective promotive and preventive strategy based on community empowerment for sustainable dengue prevention.
