ABSTRACT
(Salakory. Melianus.,MKes. Program Doktor FK. UGM - 2010)
Up to the year of 1979 Geohelminth (GH) infection remains the public illness with high prevalence in tropical countries, particularly on low income families in rural areas (Moetrarsi et al., 1980).
In Ambon islands, the data on GH collected from monthly village health center reports since 2004, 2005, and July 2006 showed the varied results: there is village health center with the highest and lowest prevalance, and the other with prevalence report on the position in between highest and owest prevalance. It is also seen in the areas with certain geographical conditions having the highest prevalance in particular GH infection and vice versa.
The study on GH by using the eco-epidemiologic approach which is supported by the remote sensing data and the Geographic Information System (GIS), and hoped the symptom of the varied GH infection occurance can be explained through the laboratory experiment supported by the field survey. This research focuses on the particular GH widespread in relation to the GH eggs and larvae concentrations on soil and its effect on the GH prevalence infection in society.
The aim of this research is to undestand distribution of the GH eco-epidemiologic conditions, the dynamic of the infective eggs and larvae population in rural areas of Ambon islands, the GH prevalence rural population in this region, as well as determinant factors toward the dynamic of eggs and GH larvae development on the soil and GH prevalance on the population of Ambon islands.
The research design uses experimental at laboratory supported by the field survey with cross sectional method.
The result of research: (1) from the outcome of culture at laboratory found out six growth of dynamic formulas and 63 growth index formulas for each type of egg and larvae based on its dish. Dish media is soil based on its type which is continuously wet (rainy season) and dry (drought season) and moist (2) The distribution of GH eco-epidemiologic conditions, dynamic of infective GH egg and larvae population on the soil, and GH prevalance on the population.(3) Determinant factors to the dynamic of egg population and GH larvae on the soil, GH prevalance on the population. The similarity regression of variables provided contribution to dynamic of egg development and GH larvae on the soil described below:
Y (T&L.GH)= -4.228(Const)+2.698(BD/X1)+0.129(KT/X2)+0.454(pH/X3)+
0.017(KAL/X4)+0.012(TDI.Al/X5)+0.017(TDI.Tt.X6)+
0.082(TID.Hw/X7)
R. Square number on Model Summaryb output is 0,57.
The similarity of regression of varibels provided contribution to GH infection prevalance on the population of Ambon islands can be seen as follows
Y (Prev.GH)= 0.012(Const)+0.850(TEL/X1)+0.29(AKTV/X2)+0.862(LR/X3)+
1.214(Br.H/X4)+0.376(CT/X5)+ 0.084(MPT/X6).
R square number on output Model Summaryb is 0.96
4. The spatial distribution map of GH eco-epidemiologic conditions (risk factor), GH, population dynamic on the soil based on the land unit, as well as GH prevalence on rural population based on land unit of Ambon islands
Key Words: eco-epidemiology, GH population dynamics, prevalence
