Background: The Aedes aegypti mosquito transmits the viral disease dengue hemorrhagic fever (DHF), a significant public health problem in many tropical countries. The 1 House 1 Larva Monitoring (G1R1J) Movement, which involves every household as a mosquito larva monitoring agent, is one of the efforts to help communities control mosquito growth. Dengue Hemorrhagic Fever (DHF), transmitted by the Aedes aegypti mosquito, remains a significant public health issue in many tropical regions. The “1 House 1 Larva Monitoring” (G1R1J) movement, which mobilizes households as mosquito larvae monitoring agents, represents a community-based approach to controlling mosquito proliferation.

Objective: This study highlights a knowledge gap regarding the effectiveness of the G1R1J program with larvae-monitoring students compared to a program solely relying on larva-monitor cadres.

This study addresses a knowledge gap by comparing the effectiveness of the G1R1J program integrated with larva-monitoring students against the traditional approach relying solely on larva- monitor cadres.

Materials and methods: This study used a comparative design to compare the efficiency of the G1R1J program with the number of DHF cases in two DHF-endemic areas in Pariaman City, West Sumatra. A comparative study was designed to evaluate the efficiency of the G1R1J program concerning the incidence of DHF cases in two endemic areas in Pariaman City, West Sumatra. The researchers focused on field surveys and community attitudes because these aspects are directly linked to the implementation and success of the G1R1J program.

Results: The main results, with p=0.000 and OR 0.03, showed that comprehensive field-based interventions can significantly reduce the risk of vector presence. The study also demonstrated the importance of community attitudes in vector control, with p=0.002 and OR=0.15, suggesting that positive attitudes towards vector control practices can enhance the program’s effectiveness. Statistical analysis revealed significant results, with a p-value of 0.000 and an odds ratio (OR) of 0.03, indicating that comprehensive, field-based interventions markedly reduce vector presence. Additionally, the study highlighted the role of community attitudes, with p=0.002 and OR=0.15, underscoring that positive perceptions and practices towards vector control significantly enhance program effectiveness.

Conclusion: This study shows that integrating the G1R1J program with larvamonitoring students can reduce the density of Aedes Aegypti mosquito vectors and dengue fever incidence. In addition, it offers strategic guidance for building more sustainable and efficient vector control policies in other endemic areas. Integrating the G1R1J program with larvae-monitoring students reduces Aedes aegypti vector density and DHF incidence. This approach offers strategic insights for developing sustainable and efficient vector control policies in other endemic regions.
