Abstract

Hydrodeoxygenation (HDO) reaction of furfural derivatives have widely studied because these reaction produce saturated alkane which potensial for renewable fuels. Nickel based catalyst impregnated in to ZrO2-SiO2 (Ni/ZrO2-SiO2) was prepared and its activity is evaluated for HDO of furfurilidene aceto (FAc) and difurfurilidene acetone (F2Ac). Ni/ZrO2-SiO2 catalys was prepared from Ni(NO3)2.6H2O with 10% Ni loading over ZrO2-SiO2 by wet impregnation method. Characterization using X-ray showed the diffraction of Ni detected at 2θ = 44.42, 51.73, and 76.26. Catalyst activity for HDO of FAc and F2Ac was carried out at 200oC for 2 hours in batch system. According to gas chromatography analysis, the conversion of product is 100% with selectivity for 2-octanol and dodeka-6-ene is 88,22% and 2,99%, respectively.

Abstract

Introduction: The presence of landfills can threaten groundwater quality because the decomposition process of waste containing hazardous chemicals can cause surrounding groundwater pollution. As the amount of waste increases, the risk of environmental pollution around the landfill also increases, especially to groundwater sources used by the local community. The study aims to analyze family health problems related to the use of groundwater located near landfills. Methods: The study used a cross-sectional design around the Kebon Kongok landfill, West Lombok, West Nusa Tenggara (WNT), Indonesia. The sample amounted to 300 respondents who met the inclusion criteria. Data analysis was performed descriptively, chi-square test, and binary logistic regression by analyzing the adjusted odds ratio (AOR) results, p-value <0.05, and 95% confidence interval. Results: 164 respondents (54.7%) used well water for their daily needs. The results of the study based on binary logistic regression tests showed a significant relationship between history of diarrhea in children (p=0.002; AOR=3.65), nutritional status of the child (p=0.001; AOR=3.95), maternal history of fetal miscarriage (p<0.001; AOR=4.08), family history of skin disease (p=0.010; AOR=2.75), family history of ARI (p=0.011; AOR=2.72), disability status in the family (p<0.001; AOR=4.10), family history of chronic disease (p<0.001; AOR=4.79), history of mother giving birth to a low birth weight (LBW) infant (p=0.003; AOR: 2.97), and history of mother giving birth to a premature infant (p=0.009; AOR=2.64) with the use of groundwater in families around the landfill. Conclusions: Groundwater use near contaminated waste disposal sites is closely related to family health issues related to diarrhea, nutritional status, fetal miscarriage, skin diseases, ARI, disability, chronic diseases, LBW, and history of mother giving birth to a premature infant. This indicates the need for significant health and environmental interventions to protect surrounding communities from the health risks of using polluted groundwater.
