Background. Malaria was endemic disease in Papua which it’s prevalence from the past until present was still similar. Malaria disease was the number one of the death cause in Papua although the local government had strived for some restraints methods for malaria such as using mosquitoes’ net, larva eradicating, and routine medical treatment for the malaria sufferers, but these efforts didn’t work. This research was aimed to know and analyze the correlation between: (1) physical environment risk and malaria spreading, (2) biotical environment risk and malaria spreading, (3) social factor risk and malaria spreading, (4) condition of location of mosquitoes’ and larva’s propagation, and buffer zone (malaria potential area) as the location of mosquitoes’ distribution and malaria spreading in Sentani Lake area. Method. Population in this research were all population in Sentani District in the number of 47.758 persons. Sample in this research were 200 persons from 4 villages: Yoboi/Kehiran Village, Hobong Village, Ifar Besar Village, and Ifale Village, from each village it were taken 50 persons. The sampling technique was done randomly. The data collecting used questionnaire, observation, interview, and documentation. The analysis method used bivariate analysis, statistic test of Chi-Square, and logistic regression test. Result. Based on the analysis result, it could be known that physical environment had meaningful correlation with malaria incident that showed with Chi-square value of 7.531 with p = 0.006 < 0.05 and logistic regression result with OR value of 4.132 with p = 0.009 < 0.05. Biological factor had meaningful correlation with malaria incident that showed with Chi-square value of 16.328 with p = 0.000 < 0.05 and logistic regression result with OR value of 2.117 with p = 0.017 < 0.05. Social factor had correlation with malaria incident that showed with Chi-square value of 9.737 with p = 0.002 < 0.05 and logistic regression result with OR value = 3.704 with p = 0.014 < 0.05. The using of GPS in spatial analysis had meaningful correlation toward the coordinate measurement of place of mosquitoes’ and larva’s propagation that could help the restraint of malaria mosquitoes in Sentani Lake area. Conclusion. Result of hypothesis test showed that factors of physical, biological, and social environments were significantly influenced toward malaria incident in Sentani Lake area. Suggestion. It was needed to give counseling to the societies especially in order to change their attitude and behavior in using the mosquitoes’ net, closed clothes at the night, and using anti mosquitoes’ lotion. Else, it was needed to reorder the settlements, and plant zodia in front of the house. Key words: Environment (Physical, Biotical, Social), Spatial Analysis, And Malaria Incident.
