Abstract

Air pollution is a major environmental problem in Indonesia, especially in urban and industrial areas. This study aims to identify regions potentially affected by air pollution using the WRFChem model. Simulations were conducted to analyze the distribution of PM10 pollutants in July, during the Australian monsoon. The simulation results show that most regions in Indonesia remain within safe limits, with PM10 concentrations below the threshold of 75 μg/m³. However, several major cities on the island of Java, such as Jakarta, Tangerang, Yogyakarta and Surabaya, experienced elevated concentrations exceeding the air quality standard. In addition, monsoon wind patterns caused pollutants to spread northward, increasing concentrations in the provinces of Lampung and South Sumatra. These findings highlight the importance of monitoring air quality and implementing mitigation strategies to reduce the impact of air pollution on public health and the environment.

Abstract

Antimicrobial resistance (AMR) and climate change are major global public health challenges, with growing evidence indicating interconnected relationships. This review explores the multifaceted links between climate change and AMR, focusing on how rising temperatures influence bacterial resistance mechanisms, alter pathogen distribution patterns, and affect environmental reservoirs of resistance genes. Evidence synthesized in this review indicates that rising temperatures correlate with increased AMR rates across multiple regions, with each 1°C temperature increase linked to higher resistance prevalence. Climate change affects environmental transmission dynamics via soil ecosystems, aquatic environments, and cryosphere degradation, which can release long-dormant resistance determinants from permafrost and glaciers. Rising temperatures facilitate the geographic spread of resistant pathogens, as observed in Vibrio species expanding to higher latitudes and the emergence of Candida auris as a clinically significant pathogen from environmental sources. Wildlife and livestock act as potential reservoirs, while climate-driven habitat changes increase human-animal interactions that may facilitate transmission. The bidirectional relationship between these challenges—where rising temperatures contribute to AMR spread and resistant infections may hinder climate resilience—requires integrated One Health approaches. Strategies proposed include enhanced surveillance, climate-informed antimicrobial stewardship, and ecosystem-based interventions to address these interconnected issues. Importantly, integrating climate-informed health policies that align climate adaptation with AMR control should be prioritized globally to safeguard antimicrobial efficacy amid accelerating environmental changes.

Abstract

Abstrak Mekanisme kimia polutan dan parameter meteorologi merupakan bagian penting dalam menentukan sebaran polutan. Dengan mengetahui parameter tersebut, maka dapat diestimasi arah persebaran polutan dan besaran dampak yang ditimbulkan di lingkungan. Hal ini dapat diestimasi menggunakan pemodelan numerik seperti WRF-Chem. Model ini merupakan kombinasi dari prediksi cuaca dan proses kimia atmosfer. Penggunaan mekanisme kimia yang berbeda dalam menjalankan model WRF-Chem akan berdampak pada keluaran model. Oleh karena itu, perlu dilakukan analisis lebih lanjut tentang penggunaan mekanisme kimia yang berbeda dalam model WRF-Chem. Penelitian ini memanfaatkan fire inventory untuk mekanisme kimia polutan yang dikeluarkan oleh NCAR, yaitu GEOS-Chem, SAPRC99, dan MOZART. Studi kasus yang digunakan dalam penelitian ini adalah saat kejadian kebakaran hutan di Provinsi Riau pada bulan September 2019, dengan fokus analisis pada karbon monoksida dan particulate matter (PM10). Metode yang digunakan dalam penelitian ini adalah melakukan analisis menggunakan parameter statistik, seperti korelasi, bias, dan RMSE untuk mengetahui tingkat akurasi model. Dari hasil simulasi, skema MOZART merupakan skema terbaik dengan korelasi sedang hingga kuat. Namun, seluruh skema dalam simulasi ini cenderung underestimate dan memiliki nilai error yang tinggi terhadap observasi. Hal ini menunjukkan bahwa skema kimia dari fire inventory masih mempunyai tantangan besar dalam memprediksi nilai konsentrasi polutan. Untuk arah sebaran, MOZART, dan SAPRC99 menunjukkan pola spasial yang mirip dengan citra satelit.   Abstract The chemical mechanisms of pollutants and meteorological parameters play a crucial role in determining the distribution of pollutants. Understanding these factors enables the estimation of pollutant dispersion direction and its potential environmental impact. It can be estimated using numerical models, such as WRF-Chem, a coupled system integrating weather prediction and atmospheric chemical processes. The use of different chemical mechanisms within WRF-Chem influences the model output. This study aimed to evaluate the spatial and statistical performance of the WRF-Chem model using three different chemical mechanisms—MOZART, GEOS-Chem, and SAPRC99—from the FINN emission inventory, during a forest fire episode in Riau Province in September 2019. The analysis focused on carbon monoxide (CO) and particulate matter (PM₁₀), using statistical metrics such as correlation, bias, and RMSE, along with spatial validation against Sentinel-5P satellite imagery. Simulation results showed that the MOZART mechanism provided the best overall performance, exhibiting moderate to strong correlation with observational data. However, all chemical schemes tended to underestimate pollutant concentrations and showed relatively high error margins. Spatially, MOZART and SAPRC99 demonstrated dispersion patterns closely aligned with satellite observations. These findings highlight the potential and limitations of current chemical mechanisms in accurately simulating pollutant dispersion during forest fire events.
