Abstract

Air pollution comes from construction activities in the development of educational infrastructure buildings because it has an impact on changes in green open space and an increase in air pollution, especially Carbon Monoxide (CO) emissions in the air. The contribution of increasing CO2 and CO emissions can be sourced from all activities of workers who use energy such as procurement of building materials, use of transportation fuels, electricity use activities, and LPG use activities. Carbon footprint is a measure of the total amount of carbon dioxide (CO2) emissions that come from activities or accumulations from daily activities. This study aims to determine the amount of carbon Monoxide (CO) and CO2 emissions as indicators of air quality at the Miftahun Najah Islamic Boarding School. Measurement of Carbon Monoxide (CO) parameters was carried out for one week with 7 samplings in the morning and samplings in the afternoon in situ. Measurements using the Lutron GCO-2008 CO meter and carbon footprint calculations using the IPCC 2006 method. The measurement results were obtained in the afternoon with a total of 9,926 mg/Nm3 and the lowest in the morning was 1,102 mg/Nm3. Air temperature in the morning to evening ranged from 29oC – 36oC. The results showed that the concentration of Carbon Monoxide in the development of Islamic boarding school buildings was still below the quality standards set according to Government Regulation No. 22 of 2021, namely10,000 μg / Nm3.

Abstract

One of the biggest environmental issues today is plastic waste. This waste cannot be avoided and continues to increase which in its decomposition takes 50-100 years and will be fragmented into smaller forms called microplastics. Microplastic measuring < 5 mm with various shapes. The people of the Nipah Panjang area dispose of plastic waste into the Batanghari River which is likely to cause microplastic content. To determine the number of microplastics, it is necessary to identify the abundance of microplastics found in the Nipah Panjang area on the Batanghari River using quantitative methods. The tool used is Planktonet mesh 150 with a diameter of 20 cm. The sampling process was carried out for one day with two samplings, namely in the morning at low tide at 09.00-11.00 WIB and in the afternoon at high tide at 15.00 WIB. The study's results were sampling in the morning at low tide with 327 microplastic particles and the highest in the afternoon at high tide, namely 443 microplastic particles. The temperature in the morning and evening ranges from 29°C - 32°C. The results showed that four types of microplastics were found, namely the type of fiber, filament, fragment, and granule. From the four locations of Sungai Air samples, the most microplastic fragments were found with a total of 353 particles, the second most were filament types with a capacity of 191 particles, the third type of fiber with a total of 186 particles, and the least types of granules with a total of 40 particles. Microplastic at low tide is lower than at high tide. The abundance of microplastics from the four sampling locations of river water is 25,666.67 particles/m3.

Abstract

Biochar is a solid material formed from the carbonization of biomass. Biochar is the result of the conversion of organic waste by using the incomplete combustion method with a limited oxygen supply (pyrolysis). Meanwhile, the rubber scrap waste from the production of crumb rubber has not been utilized much other than as a mixture of fertilizer in the soil. This study aims to analyze the effectiveness of biochar as a peat water filtration media and the effect of biochar thickness on removal efficiency. Variations used are 100% biochar, 75% biochar – 25% silica sand, 50% biochar – 50% silica sand with three times repetation in each variation. with peat water test parameters are pH, color and organic matter (KMnO4). Parameters tested were pH, color and organic matter (KMnO4). The results showed that biochar was effective in neutralizing pH where the initial pH increased to 7.2, 4.2, color removal up to 75% and organic matter (KMnO4) up to 83%. The best variation is achieved at a ratio of 50% biochar – 50% silica sand. Variations that use 100% biochar actually provide lower removal efficiency. The combination of biochar with silica sand can further improve pollutant removal in filtration system.

Abstract

The laundry business is one of the household-scale businesses that is currently developing in Jambi City. This is possible because the number of laundry business customers is increasing along with the increase in the population in the city of Jambi and the increasingly diverse activities of the people of the city of Jambi. The laundry business in Jambi City is more than 300 units, so if the laundry waste is not treated first, it will have the potential to cause environmental pollution because of the compounds it contains. This study aims to determine the efficiency of the electrocoagulation process to decrease parameters in laundry wastewater, while the parameters observed are pH, COD (Chemical Oxygen Demand), and Phosphate (PO4). Cause pollution to the surrounding environment, especially in receiving water bodies. Variable voltage (voltage) in the electrocoagulation process is 9 volts, 12 volts, and 15 volts with a reactor capacity of 12 liters with a time of 30 minutes and 60 minutes at each voltage. Decreasing parameters were analyzed by comparing pH, COD (Chemical oxygen demand), and Phosphate (PO4) before and after the study, as well as the effect of voltage (voltage) and contact time on the effectiveness of decreasing parameters. The highest percentage of COD reduction efficiency is 80%, Phosphate Parameter is 92%. Voltage (voltage) and contact time also affect the results of parameter removal.

Abstract

Leachate resulting from the decomposition of organic waste is still a challenging problem, especially in landfill management.  Constructed wetlands (CW) are effective, economical, and environmentally friendly options to treat landfill leachate. Biochar added into CW as a pollutant adsorbent in leachate treatment.  This study aimed to determine the effectiveness of sub-surface flow CW amended with biochar in reducing leachate pollutants. Biochar was synthesized from crumb rubber scrap waste using pyrolysis. The variation biochar in CW i.e. CW0 without biochar as a control system, CW1 10% biochar, CW2 20% biochar, and CW3 30% biochar.  Leachate samples flowed into each CW reactor for 10 days of retention time.  The scanning electron showed that the biochar pores ranged from 5-10 կm, containing elements of C, O, Ca, N, Mg, Al, Si, and Fe.  Some elements have greater cumulative mass and atomic percentage values i.e. C 34.51%, O 26.54%, and Ca 21.85%.  The result of CW treatment showed that the CW system was able to remove 76-88% BOD5, 70-87% COD, and 67-81% TSS.  The addition of biochar in CW increased pollutant removal by 7-14%, showing that biochar is able to increase pollutant adsorption in wastewater and improve CW performance. Furthermore, converting organic waste into biochar is highly recommended as a sustainable way to generate useful resources.
