Analisis Risiko Asupan Oral Pajanan Mangan dalam Air terhadap Kesehatan Masyarakat

Manganese that can be found ubiquitously in the air, soil, and water is an essential nutrient for humans and animals. Inadequate intake or over exposure can cause adverse health effects. Although manganese is an essential nutrient at low doses, chronic exposure to high doses may be harmful. Regardless, the nervous system has been determined to be the primary target organ with neurological effects generally observed. The objective of the study is to assess the health risk of manganese exposure from the well drinking water intake. This study was done in Final Disposal Site Rawakucing area and outside of this area. The number of subjects were 114 who lived inside the site and 177 who lived outside the area, respectively. Study design is cross-sectional with hypotheses testing. The result showed that the average manganese concentration was 4.3 mg/l (SD=2.8873), 0.300 mg/l (SD=0.1888) respectively. The result was significant different statistically (p<0.05) for manganese concentration from two study area. The average RQ showed 0.2347 (SD=0.5095) for RQ in Disposal Site Area and 0.2955 (SD=0.2465) for RQ outside Disposal Site Area. The result was statistically significantly different (p<0.05) for RQ value, with OR=8.109 (95% CI = 2.668-24.650)

The Effect of Toluene Exposure on Central Nervous Disorder Among Printing Workers

Background: The use of toluene in printing dominates the use of metal chemicals. Toluene is used in 75% of printing work activities. Accumulation of toluene concentrations in printing can cause health problems to workers. The purpose of this study was to analyze the effect of toluene exposure on central nervous system disorders in printing industry workers.Subjects and Method: This study was cross-sectional in the printing industry in Medan, North Sumatra. The population consists of 50 people with consecutive sampling technique sampling. Data on subjective symptoms of central nervous system disorders were measured by the German version of the Q18 questionnaire. The data were analyzed using multiple logistic regression tests.Results: Subjective symptoms of central nervous system disorders increased with tenure ≥2 years (OR = 4.19; p = 0.018) and smoking (OR = 8.91; p = 0.001). Subjective symptoms of central nervous system disorders decreased with age ≤30 years (OR = 0.17; p = 0.004), female sex (OR = 0.50; p = 0.002).Conclusions: The most dominant variable affecting the subjective symptoms of central nervous system disorders is the smoking habit variable with a probability value of 0.92 or 92%.Keywords: subjective symptoms, central nervous system disorders, workers, a printing industryCorrespondence: Samuel Marganda.

Waste Management Analysis in Subulussalam, Aceh

Background: The Ministry of Environment noted that the average Indonesian population produces about 0.5 kg of waste per day or 125 million kg of waste from the total population of Indonesia. This condition will continue to grow in accordance with environmental conditions. The World Bank data showed that the amount of solid waste produced nationally reached 151,921 million kg of garbage per day, of which 80 percent was only collected, the rest was polluted by the environment. Waste management that is not sanitary can lead to environmental pollution. Waste generated by Subusalam municipal communities and transported to the landfill was 126 m3/ day, with service level 42% of the total amount of waste generation 542 m3/ day. This study aimed to analyze waste management in Subulussalam, Aceh, 2017. Subjects and Method: This was a descriptive qualitative study conducted at Subulussalam final waste disposal in 2017. A sample of 40 informants who worked at sanitary office was selected for this study. The data were collected by in-depth interview, questionnaire, direct observation and document review. Results: Waste management had not been based on the creation of a healthy environment due to: (1) No separation between organic and inorganic waste; (2) Waste that was not transported became a cause of accumulation. The final waste disposal system should prevent people from disturbing public health and not polluting water sources. In terms of financing, the final waste disposal showed an increasing waste management levy with an average increase of 25.2% per year. The increase in revenue from this levy should be offset by an improved waste management in the landfill. Conclusion: Waste management conducted by Subulussalam City Government as a whole has been good but not environmentally sound. Keywords: waste management, environmental, analysi
