Abstract

Serang Regency, with an area of 1,467.35 km2 in 2020 had a population of 1,622,630 people. By referring to SNI 19-3983-1995, the waste capacity produced on average is 2.25 liters per person per day, so the potential waste in Serang Regency in 2020 is around 1,212,903.7 m3 /year, while the amount of waste that can be transported to the final waste processing site (or TPA) is 98,339 m3 . Based on this data, waste services in Serang Regency have only reached 7.37%, far from the target of the Serang District Regional Policy and Strategy (Jakstrada) of 74% as stated in the Serang Regency Regulation No. 6 of 2021. On the other hand, there are still many roadside piles of waste in Serang Regency, which indicates that there is still a lack of community participation in waste management. Waste management involves several factors, including institutions or organizations, laws, regulations, management financing, technical and operational waste, as well as community attention and participation. Looking at the phenomenon, analysis of waste management factors in Serang Regency was carried out so that the dominant factors in improving waste management performance could be identified for further planning of strategies to optimize waste management, both through waste handling and waste reduction. Based on the analysis carried out using SPSS, it can be stated that factors of operational technical, organizational, legal, and regulatory, as well as factors of financing and community participation are suitable to be used as a policy combination to improve waste management performance in Serang Regency.

Abstract

One of the risks associated with climate change is carbon dioxide (CO2) emission, which can negatively affect human health and the ecosystem. The CO2 emission can lead to a decline in urban area quality that surpasses the environment's carrying capacity. This research aimed to investigate the relationship between CO2 Emissions from Transportation (X1), Household (X2), and Business Sector (X3) with the CO2 reduction of green open space (Y). The hypothesis is that there is a negative correlation between CO2 emissions from transportation, households, and businesses and CO2 reduction from green open spaces. A quantitative research design was adopted using the Slovin formula and cluster random sampling. The Normality and Homogeneity Tests are used to analyze research data. The study yielded the following results: first, the coefficient of determination (r2) = 0.003 indicates a relationship between CO2 emissions from transportation with CO2 reduction from green open space, with a 0.3% contribution. The second finding is that there is a 0.1% contribution from CO2 reduction from green open space to the CO2 emissions of households, as indicated by the coefficient of determination (r2) = 0.001. Third, a correlation of 0.1% between CO2 reduction from green open space and CO2 emissions from the Business Sector is indicated by the coefficient of determination (r2) = 0.001. Thus, using the regression equation Y = 2320.432 – 0.16X1 – 0,25 X2 – 0,007 X3, there is an overall significant relationship between CO2 emissions from transportation, CO2 emissions from households, and CO2 emissions from the business sector with the reduction of CO2 from green open space. Salah satu risiko yang terkait dengan perubahan iklim adalah emisi karbon dioksida (CO2), yang dapat berdampak negatif terhadap kesehatan manusia dan ekosistem. Hal ini dapat mengakibatkan penurunan kualitas kawasan perkotaan hingga melampaui daya dukung lingkungan. Penelitian ini bertujuan untuk mengetahui hubungan Emisi CO2 dari Transportasi (X1), Rumah Tangga (X2), dan Dunia Usaha (X3) dengan penurunan CO2 pada Ruang Terbuka Hijau (Y). Hipotesisnya adalah terdapat korelasi negatif antara emisi CO2 dari transportasi, rumah tangga, dan dunia usaha dengan penurunan CO2 dari ruang terbuka hijau. Dengan menggunakan rumus Slovin dan cluster random sampling, desain penelitian yang digunakan adalah kuantitatif. Uji Normalitas dan Homogenitas digunakan untuk menganalisis data penelitian. Penelitian ini menghasilkan hasil sebagai berikut: pertama, koefisien determinasi (r2) = 0,003 menunjukkan adanya hubungan antara emisi CO2 dari transportasi dengan penurunan CO2 dari ruang terbuka hijau, dengan kontribusi sebesar 0,3%. Temuan kedua, terdapat kontribusi penurunan CO2 dari ruang terbuka hijau terhadap emisi CO2 rumah tangga sebesar 0,1% yang ditunjukkan dengan koefisien determinasi (r2) = 0,001. Ketiga, korelasi sebesar 0,1% antara penurunan CO2 dari RTH dengan emisi CO2 dari Dunia Usaha ditunjukkan dengan koefisien determinasi (r2) = 0,001. Dengan demikian, dengan menggunakan persamaan regresi Y = 2320.432 – 0.16X1 – 0,25 X2 – 0,007 X3, secara keseluruhan terdapat hubungan yang signifikan antara emisi CO2 dari transportasi, emisi CO2 dari rumah tangga, dan emisi CO2 dari dunia usaha dengan penurunan emisi CO2 dari ruang terbuka hijau.
