Abstract

The population growth in Bogor City is increasing every year, which can be seen from the population data from 2018 to 2022, increasing by 84,934 people with a population growth percentage of 2.07%. As the population grows, the demand for clean water will increase. This will also have an impact on the amount of domestic wastewater produced. In 2021, access to adequate sanitation in Bogor City will only be 75.35%, while it should reach 100% to achieve the SDG targets. Therefore, in order to achieve adequate sanitation, it is necessary to have a domestic wastewater treatment plant (WWTP) and assess IPAL so that the domestic wastewater produced can be safely discharged into the environment. A WWTP consists of several treatment units such as an intake building, an anaerobic pond, an aerobic pond, a facultative pond, a maturation pond and a sludge drying bed. The WWTP can be evaluated by comparing the effluent after treatment with quality standards, namely the Minister of Environment and Forestry Regulation No. 68 of 2016. The evaluation results show that several parameters still do not meet the quality standards for effluent to be discharged into the environment. These parameters are BOD and total coliform. Meanwhile, the percentage of TSS parameter removal was 57.14%, BOD 26.34%, COD 64.28%, Ammonia 69.88% and Total Coliform 99%.

Abstract

One of the causes of global warming is the presence of carbon emissions in the atmosphere. Carbon emissions trapped in the atmosphere will cause the Earth's average temperature to rise. Therefore, it is necessary to calculate and map carbon footprints to anticipate the effects of global warming, one of which is in the city of Bogor. The energy sector is the sector that contributes 43.83% compared to other sectors. The calculation of the carbon footprint is based on IPCC formulas. Meanwhile, data collection is carried out through the distribution of questionnaires and direct interviews with the residents of Bogor City in 6 sub-districts. The calculated carbon footprint of the energy sector comes from residential activities, namely the use of fuel for cooking, fuel oil for motor vehicles and electricity used during 1 month. The results of the energy sector carbon footprint in Bogor City were then mapped at different levels using QGIS. The calculation of CO_2 emissions in Bogor City resulted in 2,244,809.6 tons/year and was dominated by North Bogor District as the largest contributor of CO_2 emissions.
