Malaria cases in this region are afected by local conditions, including the climate and environment of aquatic habitats.Te purpose of this study was to analyze the ef- fect of climatic factors and habitat characteristics on Anopheleslarval density in Koya Barat village. Te method used is feld observation with descriptive and statistical analy- sis approach.Te results showed that there are four parameters that signifcantly afect on larval density, namely rainfall, air temperature, water temperature and salinity. Te relationship between rainfall with the larval density in freshwater permanent habitat is negative linear. While in brackish water permanent habitat and semi permanent habitat is non-linear (2nd order polynomial). Te relationship between air temperature, water temperature and salinity with the larval density in freshwater habitat are positive linear, while in brackish water habitat and semi permanent habitat are negative linear.  Correspondence Address: Jurusan Fisika, FMIPA, Universitas Cenderawasih.

Trend of malaria incidents on Papua provice during 2012-2016 were fuctuate time to time, which is 60.56 per 1000 population in 2012 became 42.65 per 1000 population in 2013. Tere was signifcant decrease in 2014 which became 29.57 per 1000 population yet the next two years increased to 31.93 per 1000 population in 2015 and 39.93 per 1000 population in 2016 (Ministry of Health, 2017). Based on the data, malaria is cathegorized as top 10 disease on the region. It scatters on nearly all region on Papua, including Jayapura which is the capital of the Province. One area on Jayapura having highest Introduction Nowadays, malaria still become a serious community problem for some regions in Indonesia. It can reduce work productivity and resulting of mortality for high risk group which are baby, children under fve years and pregnant mother. Malaria incident rate in Indonesia during 2012 – 2016 tends to decrease with 1.69 per 1000 population in 2012 to 0.77 per 1000 population in 2016 (Ministry of Health, 2017). Tough, malaria incident rate on east region of Indonesia still quite high particularly on Papua and West Papua province. Both are malaria endemic region with high case incidence (API>5) cathegory. Refer to Annual Paracite Incidence (API) in 2016, Papua province has
