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

Environment through the provision of parks and green open spaces (RTH), is carried out area and number of residents spread across the Jambi. urban areas is very necessary. Parks are needed to maintain land availability, as water catchment areas, which can play a role in helping water absorption, so that the supply of water in the ground (water saving) increases and reduces the potential for flooding, by reducing the amount of water runoff. This study used a quantitative descriptive method with research from the Jambi City Statistics Center (BPS). The research was carried out in the Administrative Region of Jambi City. The results of the analysis provision of public green space based on the area need for public green open space in Jambi City is 3,617.50 ha. The available public open space area is around 779.02 ha. Based on these results, there is a difference in the area of 2,838.48 ha, and the provision of public green open space based on population according to Minister of Public Works Regulation Number. 5 of 2008 it can be seen that the need for a park area in Jambi City is 1,243.70 ha. The available garden area is approximately 188,388.27 m2 or 18.84 ha. Based on these results, there is a difference in area shortage of 1,224.86 ha. Jambi City over the past 13 years (2020-2033) Some strategies Increasing the area of public open space in fulfilling intrinsic and extrinsic functions, socializing the availability of green space functions for life and the environment and Spatial planning that is equal to 20% for public open space from the total area of the city. The area of green open space in Jambi City is only 779.02 ha and is very far from the area of Jambi City which is ± 20,538 ha.

Abstract

Domestic waste comes from households that must be treated. Based on the Minister of Environment and Forestry Regulation Number P.68/Minister Environment and Forestry-Secretary General/2016 concerning Domestic Wastewater Quality Standards, the government has set a maximum limit for waste water that can be disposed of to the environment or receiving water bodies. includes pH, TSS and COD parameters. This is useful for overcoming the problem of environmental pollution caused by wastewater. Waste water that is not managed properly will have an impact on human health. environmental pollution is harmful to humans. Domestic sewage treatment using a titanium dioxide photocatalyst shows the results of testing the pH value on domestic waste as shown below, showing that overall the concentration of parameters has increased the pH value decrease 90% from acidic to normal with the best pH value with a value of 6.57 at a contact time of 210 minutes of mass catalyst 2.5 grams. Parameter concentration decreased TSS value from initial value of 157 mg/L to normal with the best TSS value of 94 mg/L at contact time of 210 minutes with catalyst mass of 2.5 grams. COD value at contact time of 210 minutes with a mass of 2.5 grams of catalyst with a value of 2861 mg/L. COD value affects the time and mass of the catalyst (1). a decrease of 40.1% where the TSS value meets the quality standard, and the COD value has decreased by 31%. Addition of further processing to get a better COD.
