Abstract

ABSTRAK  Buruknya kualitas udara menjadi salah satu masalah yang serius untuk kota-kota besar, khususnya Jakarta. Salah satu indikator dalam polusi udara adalah Particulate Matter (PM). Penelitian ini mengkaji pengaruh populasi penduduk, kasus kebakaran, luas ruang terbuka hijau (RTH), dan kadar karbonmonoksida (CO) terhadap kadar PM 2.5 di Jakarta menggunakan metode linear mixed model (LMM). Hasil penelitian menunjukkan bahwa luas RTH memiliki pengaruh signifikan terhadap penurunan kadar PM 2.5 dengan koefisien negatif, artinya semakin luas RTH, semakin rendah tingkat polusi udara. Kadar CO juga berpengaruh signifikan terhadap PM 2.5 secara mandiri. Populasi penduduk, meskipun tidak signifikan secara langsung, menunjukkan pengaruh signifikan ketika diinteraksikan dengan variabel lain terhadap PM 2.5. Di sisi lain, kasus kebakaran tidak berpengaruh signifikan terhadap polusi udara, bahkan interaksinya dengan variabel lain juga tidak menunjukkan pengaruh signifikan. Penelitian ini dapat menjadi acuan bagi pemerintah DKI Jakarta dalam menyusun regulasi dan kebijakan untuk mengendalikan polusi udara, terutama dengan memperhatikan pentingnya memperluas RTH dan mengendalikan kadar CO sebagai upaya mengurangi PM 2.5, serta mencegah dampak buruk kualitas udara terhadap kesehatan masyarakat seperti penyakit pernapasan. Kata kunci: kebakaran, kualitas udara, LMM, pernapasan, polusi ABSTRACT Poor air quality is a serious problem for big cities, especially Jakarta. This study examines the effect of population, fire cases, green open space (GOS) area, and carbon monoxide (CO) levels on PM 2.5 levels in Jakarta using the linear mixed model (LMM) method. The results showed that the area of green space has a significant effect on reducing PM 2.5 levels with a negative coefficient, meaning that the wider the green space, the lower the level of air pollution. CO levels also have a significant effect on PM 2.5 independently. Population, although not significant directly, shows a significant effect when interacted with other variables on PM 2.5. On the other hand, fire cases do not have a significant effect on air pollution, and even their interaction with other variables also does not show a significant effect. This research can serve as a reference for the DKI Jakarta government in developing regulations and policies to control air pollution, especially by paying attention to the importance of expanding green spaces and controlling CO levels as an effort to reduce PM 2.5, as well as preventing adverse effects of air quality on public health such as respiratory diseases. Keywords:  air quality, breathing, fire, LMM, pollution

Abstract

The Probabilistic Seismic Hazard Analysis (PSHA) method was used to analyze the level of earthquake hazard in West Java Province, Indonesia, which is located between two active tectonic plates. This research integrates literature study, earthquake data collection, and data processing to explore the influence of megathrust, background, fault, and combine earthquake sources on local and national vital objects in the region, such as Pusdik Kopassus, Presidential Palace, Cirebon PLTU, Geothermal Power Plant, Peacekeeping Mission Center (PMPP TNI), PT. PINDAD, PT DAHANA SUBANG, PLM GUNUNG SAWAL, Walahar Dam, PT Indonesia Power UJP Jabar 2 Pelabuhan Ratu, which have important roles in critical infrastructure, defense, and national resilience. The analysis shows variations in maximum ground acceleration between 0.40 g to 1.00 g for background earthquake sources, and 0.00 g to 1.00 g for fault earthquake sources. The research also underscores the importance of mitigation efforts and proper planning to reduce the potential impact of earthquakes in West Java, taking into account the crucial role of national vital objects in maintaining the stability and sustainability of the region. The implications of these findings reinforce the urgency to improve coordination between stakeholders in building earthquake resilience at the local and national levels, and highlight the importance of hazard curve analysis on national vital objects to inform the future of the region.
