Abstract

Dengue Hemorrhagic Fever (DHF) was a vector-borne disease that spreads rapidly and could cause death. Weather changes and climate change indirectly affects the incidence of dengue hemorrhagic fever. Conducive tropical weather and climate elements such as rainfall, air temperature and air humidity that are supported by the existence of habitat for Aedes aegypti mosquito could increase the risk of dengue cases. The purpose of this study was to determine the relationship between weather variability and the incidence of DHF in Tegal Regency during the period of 2012-2018. The design of this study was ecological study whereas unit analysis of the study is at population level. The data obtained was analysed by using correlation test spearman to identify correlation of the moran index on weather variability and dengue morbidity rates. The results of variability analysis were rainfall (p = 0,879; r = 0,071), air temperature (p = 0,023; r = -0,821) and air humidity (p = 0,879; r = -0,071). It was showed that the significant risk factors for the incidence of DHF in Tegal Regency was air temperatures. The study concluded that Tegal Regency has weather variability conditions that have the potential to increase the chances of dengue fever therefore intervention such as mitigation are expected to stifle the pace of climate change, and adaptation are needed to facing future impacts that related to the eradication of DHF.

Abstract

One of the water treatment efforts is disinfection. Disinfection aims to kill pathogenic microorganisms that can cause health problems for humans. One of the disinfectants that is commonly used is chlorine because chlorine is easily available and affordable. The use of chlorine as a disinfectant must meet the appropriate dosage requirements and techniques. Pelindo Semarang reservoir is disinfected with 250 grams of chlorine and is repeated once a month. This study aimed  to identify Total Coliform and E. coli on the day immediately after affixing, 7th, 14th, 21st and 28th days at the Pelindo Reservoir, Nusantara Pier Hydrant, Passenger Terminal Reservoir, Samudera Pier Hydrant, TPKS Pier Hydrant and TPKS Reservoir. Result found that the condition of the Pelindo Reservoir as the main reservoir in an open state, there is garbage around the reservoir and no drainage is carried out. Total Coliform meets the quality standard of 16.7%. Meanwhile, E. coli meets the quality standard of 13.3%. Addition of chlorine at one time is considered less effective in reducing coliforms or eliminating E coli.

Abstract

Use of groundwater as a water source in South Jakarta is quite high with a usage value of 3,768,226 m3. Most of the shallow groundwater in RW IV Bangka village are at a depth of <25 mbgl, so they have the potential to be polluted.. Moreover that village categorized as slums area, where there is high risk to be polluted by poor environment. . This study aims to analyze the level quality of Fe and CaCO3 pollution and their correlation with the risk factors in shallow well water in RW IV Bangka Village. This type of research is analytic observational with a cross sectional approach. The research population was the total number of wells in the residential area of RW IV, with the research sample using purposive random sampling of 30 shallow wells. The results showed that 100% of the samples met the requirements for pH (x̄= 8,0) and CaCO3 (x̄= 253 mg/l) levels. Meanwhile, for Fe (x̄= 0,29 mg/l) value , there were 7 samples (23,2%) that did not meet the requirements. Chi-square statistical analysis showed that there was no relationship between latrine distance (p=0,666), distance of other pollutants (p=0,675), standing water around the well (p=1,00), and SPAL conditions (p=0,304) with the Fe quality in shallow well water. However, based on the prevalence ratio (PR), the highest risk was found in other pollutant distance factors compare to others (PR=1,524).  The conclusion that, although the levels of Fe and CaCO3 in shallow well water are quite high, statistical analysis shows that there is no correlation from environment risk factors for these two value levels by reason, most of well type for sampling is bore well type which is low for contamination.
