Pada kondisi eksisting total GRK yang dihasilkan pada Kecamatan Medan Johor adalah 1.889,305 ton CO2e dan Kecamatan Medan Helvetia 1.848,375 ton CO2e. Skenario 1 menurunkan 23,25% emisi GRK pada Medan Johor dan 19,12% pada Medan Helvetia. Skenario 2 menurunkan 3,89% emisi GRK pada Medan Johor dan 2,75% pada Medan Helvetia. Skenario 3 menurunkan 40,53% emisi GRK pada Medan Johor dan 35,82% pada Medan Helvetia. Kata kunci: CH4, CO2, Gas Rumah Kaca, IPCC, Sampah Rumah Tangga ABSTRACT Household waste is one of the contributors to greenhouse gas (GHG) emissions into the atmosphere which can cause global warming and have an impact on climate change. GHG emissions generated from household waste are CH4 and CO2. This study aims to calculate the CH4 and CO2 GHG emissions from the household waste sector in Medan Johor District and Medan Helvetia District and to determine the scenario for reducing GHG emissions. There are 3 scenarios to reduce GHG emissions from the household waste sector, scenario 1 is the processing of waste at the source by composting, scenario 2 with the reduction of waste from Waste Bank community, and scenario 3 with the reduction of waste from the Integrated Waste Treatment Facility (TPST). The calculation of GHG emissions is carried out by referring to the calculation method by the Intergovernmental Panel on Climate Change (IPCC) 2006. In the existing condition, the total GHG emissions produced in Medan Johor District is 1.889,305 tons CO2e and 1.848,375 tons CO2e in Medan Helvetia district. Scenario 1 reduces 23,25% of GHG emissions in Medan Johor district and 19,12% in Medan Helvetia district. Scenario 2 reduces 3,89% of GHG emissions in Medan Johor district and 2,75% in Medan Helvetia district. Scenario 3 reduces 40,53% of GHG emissions in Medan Johor district and 35,82% in Medan Helvetia district. Keywords: CH4, CO2, Greenhouse Gas, Household Waste, IPCC

Abstract

The discrepancy between the use of vehicle fuel types and the vehicle's technical specifications is expected to affect exhaust emissions. This study aims to examine the effect of using four types of fuel with different octane number specifications on two four-wheeled motor vehicles with an EFI fuel delivery system on exhaust gas emission parameters of carbon monoxide (CO), hydrocarbon (HC), carbon dioxide (CO2) and non-emitting gases Oxygen (O2). With a quantitative experimental approach method using the Automotive Emission Analyzer and simple linear regression analysis, the results showed that the use of variations with octane numbers RON 98, RON 92, RON 90, and RON 88 fuels at the same time as variations in engine speed (1000 – 3000) RPM showed an effect on concentration. HC and CO emissions decreased with each increase in the octane number of fuel, RON 92 fuel with the lowest average CO / HC (0.0013% / 0.46 ppm) and RON 98 with the lowest average CO / HC (0.0026% / 0 ppm). The use of RON 92 fuel is more effective and inexpensive to apply to vehicles with an EFI fuel delivery system (with compression of 1:10/10.2) compared to RON 98 fuel which emits higher CO and HC emissions at low engine speed (1000 -1500) RPM.

Abstract

School sanitation is one of the development priorities included in the Sustainable Development Goals (SDGs), namely goal 4a is to build and improve educational facilities that are child-friendly, persons with disabilities, gender and provide a safe, non-violent, inclusive, and effective learning environment for all. The Development Private Elementary School is a private elementary school located in Patumbak District. This school is prioritized for the economically weak community whose parents work as laundry workers, construction workers, motorcycle rickshaw drivers and others. The foundation collects a tuition fee of Rp. 10,000/month, which is certainly not sufficient for school operational costs so that the development of school facilities and infrastructure is not up to standard. Environmental sanitation conditions in this school such as the availability of clean water is lacking, bathrooms are damaged, waste handling is not optimal, there is no place for washing hands. Based on these problems, the solution given is to improve proper sanitation conditions in the school by making boreholes with a depth of ± 10 m equipped with a pump to meet the water needs in the bathroom, renovating the bathroom, providing segregated trash cans and portable hand washing stations. In addition to providing in kind, this community service activity also provides socialization related to proper sanitation and clean and healthy living behavior to students.
