Abstract

Normally, a rural region in the developing countries, which is undergoing transformation process from agricultural economy to industrial economy, is followed by environmental degradation such as deforestation, deterioration of air quality and micro-climate. Besides, it is also acompanied by the change in family behavior in relation to their adaptaion which also leads to the prevalence of various diseases including Dengue Hemorrhagic Fever (DHF). These phenomena are being experienced by many villages in South Lampung Regency especially in the suburban area of the capital city, Bandar Lampung. This research aims to investigate the influence of environmental factors, sex, the age of toddlers and the family’s habit on toddlers’ immunity against DHF. The research was conducted from July to October 2016 in South Lampung Regency especially in the 7 districts with a relatively high number of DHF cases on toddlers namely Natar Agung Jati, Bakauheni, Ketapang, Tanjung Sari, Sidomulyo, and Katibung. The data analysis was conducted at the Forest Resource Inventory Laboratory, Faculty of Agriculture, The University of Lampung, Indonesia. The macro environmental variables investigated are the level of regional urbanism, the amplitude (maximum-minimum) of air temperature [TEMP_AM], average rainfall [RAIN], forest and agroforestry acreage [RTH_AGRF] as well as fishpond and other water bodies such as dyke, pond, retention basin and the like [RTH_POND]. The [RTH_AGRF] and [RTH_POND] data are provided through the record of Landsat satellite image interpretation that recorded on June 21, 2016, on path123/row 064 segment followed by field validation. The climate data are obtained from the Board of Climatology, Meteorology and Geophysics of Lampung especially from Branti, Panjang and Bakauheni Stations. Case data on toddlers who have been medical tested as positive for DHF on the basis of laboratory tests for the period of January 2015 to June 2016 were obtained from Health Department of South Lampung. Each case was surveyed to conduct observation on the family’s habit. The same observation was also conducted on 1 –3 families with uninfected (immune) toddlers who lived around the case location. To test the hypothesis,the log-linear model postulate is used, whose the resistant toddlers are scored by Y=1 and the affected ones are scored by Y=0. Optimization of 15 model parameters was done with Minitab 17 software at 15% of the real level. The conclusions of the variables that significantly influence are air temperature amplitude (every increase of 10C the resistance decreased to 1/1000); the area of green open space (each 1,000 ha reforestation, the resistance increased 25.05 times); the area of fishponds and ponds (every increase of 1,000 ha, the resistance increased 24.03 times), toddlers’ sex (male is 2.21 times more resistant than female); inner family’s habits: (a) using mosquitoes repellent, (b) cultivating fish, and (c) not hanging clothes where the toddlers of those who have mentioned habits are more resitant consecutively 11:48; 2.95; and 10.62 times than those who do not do the habits. It is suggested that to conduct research in other regencies as well as integrate the nutritional status and another disease history before the toddlers are affected by dengue hemorrhagic fever (DHF).
