Abstract

The community's need for clean water is a complex matter in meeting needs such as washing, cooking, bathing and other needs, so the quality and quantity need to be maintained. The Jalan Parit Wagattak area still uses drilled well water to fulfill daily needs because there is no distribution route from PDAM. The quality of iron (Fe) parameters at the research location does not meet the quality standards, namely still 1.52 mg/L. This research aims to make the drilled well water used suitable by processing it using a coagulation-filtration process. The optimum dose of chlorine obtained from the Jar Test results was 5 mg/L with a maximum stirring time of 30 minutes. The zeolite filter media used has a height of 20 cm with a PVC pipe container diameter of 3 inches. The results of the allowance for turbidity parameters from 221 NTU to 12.67 NTU (94.26%), color from 32.9 Pt-Co to <1.45 Pt-Co (95.59%), iron (Fe) 1.52 mg/L decreased to 0.04 mg/L (97.36%), Escherichia coli 16 MPN/ml to 0.89 MPN/ml (94.43%), pH increased from 6.4 to 7.2, and the remaining free chlorine (Cl2) from 0.03 mg/L to 0.04 mg/L. Based on the research carried out, it is necessary to determine the contact time between water and zeolite to eliminate turbidity and Escherichia coli happens to the maximum.

Abstract

Laundry business activities produce waste water from the washing process and have the potential to pollute water bodies. The number of domestic laundry activities is currently experiencing significant growth, as these activities increase, the amount of waste water released is also increasing. So far, the waste water produced has been directly discharged into the environment. Initial testing of the sample showed that the results did not meet the threshold according to East Java Governor Regulation No. 72 of 2013, so it is necessary to treat waste water effectively. In this research, laundry wastewater was treated using an oxidation ditch. The multilevel modified Parit Oksidasi is made from an activated sludge unit. Seeding and acclimatization takes 14 days to obtain optimum processing. The best variation uses 3 wavemaker units to reduce COD by 91.87%, phosphate by 98.49% and TDS by 57.21%. Apart from that, other contents in the sludge were also identified, namely oxygen (44.28%), carbon (21.25%), sodium (9.73%), calcium (7.11%), silica ( 4.46%), Sulfide (4.36%), Magnesium (2.73%), Chlorine (2.68%), Potassium (1.59%), Iron (0.61) and Phosphorus (0.07 %).

Abstract

Tourism is an activity that is of concern to Indonesian people, especially beach tourism, such as at Siring Pagatan Beach, Tanah Bumbu Regency, South Kalimantan. This tourism is dominated by culinary, religious, and transportation activities which have an impact on increasing the creative economy of the community. However, these activities also have the potential to cause environmental and health problems due to gas emissions and noise. To avoid the impact, it is necessary to identify and analyze the ambient air quality and noise levels at Siring Pagatan Beach. This study is essential, considering the vast potential and development of tourism activities in the research area, which is close to residential areas. In the study area, the ambient air quality, in terms of total particulates; PM10; PM2.5; NO2; SO2; and CO were measured using Indonesian National Standard No. 19-7119.6-2005 in four locations, while noise levels were carried out in 2 two locations according to Indonesian National Standard No. 8427-2017 in the study area. The results showed that the total amount of total particulates; PM10; PM2.5; NO2; SO2; and CO are 60.23-90.15; 25.07-70.02; 14.66-48.01; 0.95-5.31; 14.46-26.48; and 1917.14-1382.86 g/m3. Meanwhile, the noise obtained was 52.00-52.20 dBA. The value of these environmental components is below the threshold value in Indonesia. However, with ongoing tourism infrastructure development activities, there is the potential for increased pollutant concentrations and noise levels at the research location, which may impact the surrounding community in the long term.

Abstract

PT. Candi Jaya Amerta is an industry that produces fly ash from coal combustion in boilers and wastewater from its production processes. The utilization of fly ash in this industry has not been well optimized, and the wastewater is characterised by elevated concentrations of organic matter, primarily generated from shrimp cracker production. High organic content in wastewater can lead to environmental pollution. Goal of this research is to determine the effect of sampling time on the reduction of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels in the wastewater of PT. Candi Jaya Amerta using fly ash adsorbent through a column adsorption process system, employing the Yoon-Nelson, Adam-Bohart, and Thomas approaches. The variables employed in this study are sampling times of 20, 40, 60, 80, and 100 minutes, and adsorbent heights of 9, 13, 17, 21, and 25 cm. The research findings show that the optimal adsorbent height for reducing COD is 21 cm, with a reduction percentage of 88.2705% and a COD adsorption capacity of 7.2593 mg/g at a sampling time of 60 minutes. Meanwhile, the optimal adsorbent height for reducing BOD is 25 cm, with a reduction percentage of 98.1509% and a BOD adsorption capacity of 87.4255 mg/g at a sampling time of 60 minutes.

Abstract

Citarum River, the largest and longest river in West Java Province, is heavily polluted due to human activities such as domestic, agricultural, and industrial. This condition causes heavy metal pollution that endangers the ecosystem around the waters. This study aims to identify the level of dissolved heavy metal contamination in the upstream Citarum River, particularly in Bandung Regency, using the X-Ray Fluorescence (XRF) method, an analytical technique used to identify chemical elements in a sample by measuring the X-rays emitted after the sample is excited by primary X-rays. The test results show the concentration of heavy metals in the sediments of the upstream Citarum River, namely Fe between 67,924.8 - 47,584 ppm, Mn 406.1 - 2,107.1 ppm, Cu 54.5 - 59.7 ppm, Pb 18.8 - 22 ppm, Cr 24.4 - 29.1 ppm, and Cd 17.7 - 20.4 ppm. Sediment treatment is required when heavy metal concentrations exceed the established quality standards, especially in reducing heavy metals in industrial activity wastewater. In the deconstruction process for cadmium analysis, it is necessary to pay attention to the amount of HCL reagent solution used, because cadmium is easily dissolved by HCL. Excessive dosage can reduce or eliminate the concentration of cadmium in the sample. This research highlights the need for better waste management to maintain the water quality of the Citarum River.

Abstract

In developing countries, municipal solid waste remains a major unresolved problem. One way to manage municipal solid waste is to produce biomass. Biomass management from solid waste involves a natural or mechanically assisted biological drying process using bulking agents. This study employed natural and mechanical biodrying systems with blower assistance and corn starch industrial wastewater bulking agents. A blower expedites the process of reducing waste weight. The reactor with the blower exhibited the largest decrease in water content under the bulking agent addition conditions when the water content fell below 15%. Using a blower in the biodrying process reduces the drying time of biomass raw material by 50% compared to the non-blower method, which takes up to 12 days. 1 L of the bulking agent is the most effective biodrying dose. The percentage carbon value in the biodrying process was 42.02% higher when a bulking agent was used than a non-bulking agent (35.98%) and a blower was not used (40.82%). Including a bulking agent during biodrying enhances the composition's elemental value and speeds up the reduction and evaporation or drying of waste.

Abstract

Health facilities in East Surabaya consist of 78 facilities, but only 6 have incinerators for processing B3 solid medical waste. Health facilities that do not have incinerators collaborate on transportation and processing with other health facilities that have incinerators or third parties. A dynamic system application is applied to calculate potential Green House Gas (GHG) emissions from the transportation and processing of B3 solid medical waste from health facilities in East Surabaya using a causal loop approach. The research was carried out by measuring medical solid waste generation for 8 days and collecting secondary data. The research includes calculating the weight of medical solid waste and greenhouse gas emissions. The research results show that the weight of medical solid waste increases from year to year with the need for 16 trips per day. The generation of B3 solid medical waste from health facilities in East Surabaya is 5,019 tons/year. With this large generation, the GHG potential from transporting and processing hazardous solid medical waste from health facilities in East Surabaya is 8,200,521 tons CO2e/year.
