THE CORRELATION OF PHYSICAL ENVIRONMENT CONDITION TO LEVEL OF Aedes Sp LARVAE DENSITY AT AREA OF ELEMENTARY SCHOOLS OF KASIHAN SUBDISTRICT BANTUL DISTRICT

Abstract

Background: Data from the Health Service of Yogyakarta 2016 show that the highest dengue fever case is in Bantul District is precisely in Kasihan Subdistrict. One of the factors that influence the density of Aedes sp larvae is the physical environment including light intensity, ventilation, drainage, and distance between buildings. The results of larvae surveys show that from 11 containers, four are Aedes sp larvae, so that the Container Index obtained (CI) is 36% belonging to high density.

Objective: This study examined the relationship between physical environment condition and Aedes sp larvae density level.

Methods: This study was an observational analytic study with cross sectional design. The numbers of samples in this study were 30 elementary schools. The sampling technique employed total sampling. Data analysis employed kolmogorov smirnov with statistical significance (α = 0,05).

Results: Percentage of school are qualified in the physical environment of light (13.3%), ventilation (16,7%), drainage (56.7%), the distance between buildings (60.0%). There is 46,7% of school have a high density of Aedes sp larvae. There is a correlation between light intensity with Aedes sp larvae density (p value 0,0040), while factors which are not related to density of Aedes sp larvae are ventilation (p value 0,653), drainage (p value 0,193), and distance between buildings (p value 0.400).

Conclusions: There is relationship between the light intensity with the Aedes sp larvae density level.
