Abstract

ABSTRACT This study aims to analyze the concentration of metals in PM2.5 and the environmental health risks due to metal exposure to residents. The PM2.5 measurement using Low Volume Air Sampler (LVAS) tool with a sampling time of 3; 6; 9 hours. Meteorological conditions were measured by using the PCE-FWS-20 Weather Station tool. Analysis of metal concentrations using the Inductively Coupled Plasma-MS (ICP-MS) tool. The Environmental Health Risk Analysis (ARKL) method was used to estimate the risk of exposure. Based on the measurement results, the concentration of PM2.5 in ambient air was 25.82 µg / Nm3 and in the house was 25.73 µg / m3. The results of PM2.5 concentration measurements did not exceed quality standards based on Republic of Indonesia Government Regulation No.41 of 1999 and Minister of Health Regulation No.1077 of 2011. Three metals (Cr, Ni and Mn) which have RfC and SF values followed by ARKL calculations. The average lifetime Excess Cancer Risk (ECR) value of carcinogenic Cr metal and Ni metal that was ECR> 10-4 means that the concentration of carcinogenic Cr metal and Ni metal in the house were inhaled unsafe for occupants of adult homes and children. The average lifetime RQ value of non-carcinogenic Cr metal and Mn metal shows an RQ value> 1 meaning that the concentrations of non-carcinogenic Cr metal and Mn metal in the house were inhaled insecure for adult respondents and children. Keywords: PM2,5, risk analysis, Cr, Mn, Ni, residential ABSTRAKPenelitian ini bertujuan untuk menganalisis konsentrasi logam dalam PM2,5 dan risiko kesehatan lingkungan akibat pajanan logam terhadap penghuni rumah.

Abstract

PM 10 Pollutant is an air particulate that cannot be detected by a nose hair. It contains carcinogenic and non-carcinogenic chemical components. This study, therefore, aims to quantify the concentration of PM 10 and identify the risks of the non-carcinogenic type’s exposure to the public’s health in the commercial area of Pasar Jambi sub-district. Measurement of PM  concentration was performed on Sunday (weekend) and Monday (weekday) using high volume air sampler (HVAS). Furthermore, questionnaire and interviewing were implemented on 95 people amounting to 12% of the total population. The result shows that PM 10  concentrations were observed to have exceeded ambient air quality standards of 196.9 µg/m3 on weekend and 2.094 µg/m3 weekday. Further- more, the average concentration of Al and Mn in PM 10  were 1.69384 µg/m3 and 0.04191 µg/m3 respectively. Although the public health activity was already at the risk of PM10 non-carcinogenic exposure in the commercial district (i.e RQ 1), there has notbeen any environmental health risks for the non-carcinogenic metals (Al and Mn) to the society. Therefore, risk management is carried out to protect the population from PM risks. Risk management comprises calculating the safe concentration, duration, frequency, and time of exposure on these weekend and weekday

Abstract

AbstractBiopore Infiltration Hole (BIH) Composting is influenced by the compost raw material's type, composition, and size, the addition of additives and activators, soil texture, land use, and weather conditions. Composting performance can be improved if these factors can be optimized. This study aims to analyze the performance of BIH composting in terms of location, season, and additives. Composting is done by varying the location/season, type, and weight of additives. For locations/seasons, composting is carried out in protected areas representing the dry season and open areas representing the rainy season. Variations of additives consist of no additives, 100% sawdust, 100% rice husks, and a mixture of sawdust and rice husks with variations in the weight of additives of 1.5% and 3% of the weight of the compost raw material. The analysis was carried out on the maturity test, the quality of physical and macro elements, and the quantity of compost. The results showed that all variations of composting had met the quality standards of domestic organic waste compost according to SNI 19-7030-2004 to test the maturity and quality of compost. The addition of additives can speed up the composting time by 2-6 days and increase 7.15-35.71% the quantity of solid compost. Composting with the addition of 100% rice husk additives at 1.5% of the weight of the compost raw material and carried out in protected locations (dry season) is the most optimal BIH composting.Keywords: additives, composting, Biopori Infiltration Holes (BIH), location, season
