Abstract

Rural areas are generally synonymous with better air quality than urban areas. However, if there is an agricultural activity, it has the potential to release nitrogen from the soil, be oxidized and form NO and NO2 in the air. These two gases encourage the formation of secondary PM2.5 particulates in the air of rural areas. This study aims to analyze fluctuations in PM2.5 concentration in rural areas, the effect of its precursor NOx, and the influence of meteorological factors. The location used as a case study is the Cibeureum area, Puncak, Bogor Regency. The data used are PM2.5, NO, NO2, NOx concentration data (per 3 hours), rainfall, air temperature, wind speed and direction in 2019 and 2020, which were analyzed using correlation and linear regression and the open-air package provided by RStudio. The results showed that the concentration of PM2.5 with NOx as a precursor had a significant positive correlation in 2019 (r = 0.68) and 2020 (r = 0.63). Cumulative precipitation affects the concentration of PM2.5 and NOx in the air. Meteorological factors have a small correlation value to fluctuations in PM2.5 concentration and NOx concentration except for air temperature (r = 0.3).

Abstract

ABSTRAKPeningkatan aktivitas industri dan transportasi menjadi pemicu timbulnya potensi pencemaran udara yang berdampak pada kesehatan masyarakat, terutama di sekitar wilayah industri dan kota-kota besar. Pengenalan daerah yang rawan terhadap pemaparan konsentrasi pencemar udara maksimum perlu dilakukan untuk mengantisipasi dampak terhadap kesehatan masyarakat dan lingkungan. Studi ini bertujuan untuk menganalisis sebaran pencemar udara di sekitar wilayah industri dan menentukan lokasi yang berpotensi terpapar pencemar udara dengan konsentrasi maksimum, khususnya partikulat (dalam hal ini PM10) dan sulfurdioksida (SO2). Lokasi studi adalah wilayah Jakarta dan Tangerang, yang merupakan daerah padat transportasi juga industri. Analisis dispersi menggunakan model Weather Research Forecasting / Chemistry (WRFChem) dengan ukuran grid 4 x 4 km, selama periode 5 hari (120 jam) masing-masing pada bulan Agustus dan Desember. Hasil analisis model menunjukkan lokasi yang rawan terpapar pencemar PM10 maupun SO2 dengan konsentrasi maksimum adalah Jakarta Pusat dan Jakarta Utara, secara umum terjadi pada tengah malam hingga pagi hari. Pada siang hari konsentrasi maksimum cenderung terjadi di sekitar Jakarta Selatan, Tangerang Selatan, serta Kabupaten Tangerang. Secara temporal terjadi fluktuasi konsentrasi pencemar udara, konsentrasi siang hari rendah dan meningkat menjelang malam hari hingga dini hari. Faktor meteorologi terutama pola angin sangat mempengaruhi pola sebaran pencemar di wilayah studi, dan keberadaan garis pantai juga mempengaruhi terakumulasinya pencemar di sekitar wilayah Jakarta.ABSTRACTIncreasing industrial and transportation activity were associated with air pollution, especially in urban and industrial area. The air pollution is associated with significant adverse health effects. Understanding the potential implications of the air pollution to human health, developing strategies to mitigate the pollution should be seen as a serious attention. The purpose of this study was to analyze air pollutant dispersion within industrial area and to determine the locations that potentially exposed to maximum pollutant concentrations, especially PM10 and SO2.The evaluation was conducted within Jakarta and Tangerang using a well known modelling tool ‘WRFChem’. The WRFChem was simulated for the period of 5 days (120 hours) in August and December using the grid size of 4 km x 4 km. The model shows that the maximum concentrations of PM10 and SO2 occurred within Central Jakarta and the North Jakarta, frequently found from the midnight to morning. While during the day time, the maximum concentration tend to occur within the region of South Jakarta, South Tangerang, and Tangerang Regency. Diurnal fluctuation shows the pollutant concentrations are increased at night and decreased after sunrise. Meteorological factors, mainly wind direction, affects the pollutants dispersion in the area of study, and the existence of the shoreline also affects pollutants accumulation around Central Jakarta.

Abstract

Banjir merupakan salah satu bencana yang menimbulkan kerugian bagi manusia. Bencana tersebut biasanya didahului oleh curah hujan yang tinggi (lebat) dan lama. Proses terjadinya hujan yang tinggi dan lama memerlukan kondisi atmosfer yang mendukung seperti . Tujuan utama penelitian ini adalah menjelaskan kondisi atmosfer pada saat banjir di Kabupaten Bojonegoro tanggal 26 Desember 2007 sampai 7 Januari 2008. Hasil analisis menunjukkan bahwa kondisi atmosfer saat banjir tidak stabil, kandungan uap air tinggi, pengangkatan massa udara intensif dan kecepatan angin rendah. Kondisi tersebut cukup potensial dalam menyebabkan hujan yang lebat, meskipun kondisi atmosfer tersebut belum termasuk kategori ekstrim. Dengan demikian banjir tersebut tidak hanya dipengaruhi oleh kondisi atmosfer setempat tetapi dipengaruhi juga oleh kondisi atmosfer sekitarnya dan kondisi permukaan. Flood is one of the disasters that cause harm to humans. That disaster is usually preceded by heavy and long-term rainfall. The occurrence of high and long-term rainfall requires atmospheric conditions that supported it. The main objective of this study is to explain the atmospheric conditions while flood events in Bojonegoro on December 26th, 2007 until January 7th, 2008. The analysis showed that the atmospheric conditions are unstable during floods, high moisture content and the removal of intensive air mass and low wind speeds. The atmospheric condition during the flood was sufficient to support the heavy rain but not in extreme categories. Therefore, the flood-affected by atmospheric conditions in the surrounding area and surface conditions in that area.

Abstract

Ground level ozone is known to exhibit a strong daily variation of concentration leading to long-range transport of air pollutants from urban to rural areas. Moreover, the characteristics of O3 relationship between urban, suburban, and rural sites can be explained by O3 photochemical chemistry and meteorological dispersions as indicated by the different result of O3 diurnal pattern. However, little is known about the global phenomenon of diurnal concentration of ozone, meteorological dispersion such as long-range transport, and their correlation with ozone precursors, especially in urban and rural areas. This paper attempt to compare the difference between daily ozone fluctuations in both sites and assess some factors that cause long-range ozone transport from urban and rural areas both in subtropical and tropical areas for global scale. Using systematic literature review analysis with the PRISMA method, it examined 43 peer-reviewed articles published between 2010 and 2022 globally meeting the inclusion criteria. The result showed that the fluctuation patterns of daytime ozone in urban and rural areas are different to those in tropical and subtropical regions, depending on latitude. This was primarily due to the influence of solar radiation and the presence of precursors. Conversely, a slight decrease in ozone rate at night occurs because the precursor was accumulated by the shutdown of photochemical ozone production. Some precursors of ozone from other regions can be transported and accumulated from the long-range transport process in other locations. This paper serves as an initial guideline to analysing the pattern of ozone concentration in urban and rural areas and the factors that influence it.

Abstract

Climate interaction directly correlates with an individual's comfort response. One's comfort can be quantified by perceiving environmental conditions at tourist locations. This study aims to identify climatic and non-climatic factors that affect thermal comfort based on visitor perception. In addition, the Holiday Climate Index (HCI) is modified to equalize visitors' perceptions. The research locations, namely Taman Mini Indonesia Indah (TMII), Kebun Raya Bogor (KRB), and Taman Safari Indonesia (TSI), are characterized by distinct topographies. This study identifies thermal comfort factors based on 552 questionnaire responses from purposive sampling. Analyzing factors influencing thermal comfort using ordinal logistic regression with Uncomfortable Class (0) and Comfortable Class (1). Model performance metrics, such as accuracy, precision, recall, and F1 score, are calculated using a confusion matrix. In general, the best time to feel comfortable is in the morning. Overall, climatic factors such as thermal sensation and rainfall events influence thermal comfort, while non-climatic factors have no effect. The model's implication is to provide an equation in the probability of someone feeling comfortable or uncomfortable based on the predictors. Furthermore, a modification index at TMII adjusted the HCI-urban's weighting, ratings, and comfort thresholds to match visitors' perceptions at that time. The results demonstrate that HCI-urban effectively provides comfortable and comfortable assessments. However, it has not yet been able to capture perceptions of discomfort, unlike the modified index. This research can provide added value to the tourism industry in terms of maintaining environmental comfort during the dry season.

Abstract

Salah satu zat pencemar yang berbahaya bagi kesehatan manusia akibat peningkatan volume kendaraan dan pembukaan lahan di kota Pontianak adalah Particulate Matter (PM2.5). Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis konsentrasi PM2.5 di tahun 2022-2023, yang dipengaruhi faktor meteorologi. Data yang digunakan mencakup data konsentrasi PM2.5, dan data meteorologi berupa curah hujan, suhu udara, kecepatan dan arah angin. Metode analisis yang digunakan adalah analisis deskriptif dan statistik pengaruh faktor meteorologi terhadap konsentrasi PM2.5. Hasil penelitian menunjukkan bahwa konsentrasi maksimum dan minimum PM2.5 harian tahun 2022 adalah 30,34 μg/m ³ dan 8,01 μg/m ³. Tahun 2023, nilai maksimum dan minimum PM2.5 adalah 31,31 μg/m ³ dan 12,71 μg/m ³. Hal ini menunjukkan bahwa nilai ambang batas PM2.5 harian masih di bawah NAB, yaitu sebesar 55 μg/m ³ . Konsentrasi maksimum dan minimum PM2.5 bulanan untuk tahun 2022 pada bulan Maret adalah sebesar 39,51 μg/m ³ dan 9,32 μg/m ³. Tahun 2023, konsentrasi maksimum terjadi di bulan Agustus, yaitu 82,83 μg/m ³, dan minimum terjadi pada bulan Maret sebesar 5,29 μg/m ³. Konsentrasi tahun 2022 dan 2023 dihitung sebesar 20,06 μg/m ³ dan 22,30 μg/m ³. Hasil tersebut berada di atas nilai ambang batas tahunan yang telah ditetapkan yaitu 15 μg/m ³. Berdasarkan hasil analisis regresi memperlihatkan pada tahun 2022 faktor curah hujan dan suhu udara signifikan terhadap konsentrasi PM2.5 namun tidak untuk kecepatan angin. Nilai koefisien korelasi curah hujan dan kecepatan angin adalah negatif, sedangkan suhu udara bernilai positif. Tahun 2023 curah hujan dan suhu udara berpengaruh hampir signifikan, sedangkan kecepatan angin tidak signifikan dengan nilai koefisien korelasi sama dengan tahun 2022.

Abstract

PM2.5 is a key indicator of air quality and poses serious environmental and health concern, especially in Jakarta where air quality frequently exceeds recommended standards. But researches mainly focus on surface-level pollutant, underscoring transboundary emission. This study aims to analyze the transboundary trajectory patterns of PM2.5 pollutants, and to estimate the contribution of emissions to air quality in the Jakarta for 2024. Meteorological data and PM2.5 concentrations from five air quality monitoring stations were analyzed during non-rainfall periods. Potential emission sources analysis was simulated using HYSPLIT Concentration Weighted Trajectory (CWT). Our results show PM2.5 concentrations during the wet season were ~40% lower than dry season, with an average concentration of 27.11 μg/m3 and were strongly influenced by monsoonal wind patterns in both seasons. During the west monsoon, pollutant transport was predominantly from the southwest to northeast, whereas during the east monsoon it shifted from the northwest to northeast. The trajectory patterns exhibited no substantial differences across all layers (15, 50, 100, and 200 m), although seasonal atmospheric stability influenced pollutant dispersion. In the wet season, PM2.5 primarily originated from western regions of Jakarta, while in the dry season sources were predominantly from the east, which is consistent with prevailing monsoonal winds. Several monitoring stations also indicated potential contributions from North Jakarta due to curved airflow patterns. These findings highlight the dominant role of monsoonal wind in controlling PM2.5 concentrations and transboundary transport in Jakarta within the lower troposphere.
