Abstract: Pada musim kemarau kualitas udara sering kali menjadi isu penting terutama di wilayah Jakarta. Peningkatan jumlah hari tanpa hujan menyebabkan berkurangnya faktor pembersih udara. Kondisi cuaca ekstrem turut mendorong peningkatan jumlah hari tanpa hujan berturut-turut atau dikenal dengan istilah Consecutive Dry Day/CDD, memberi peluang akumulasi polutan di udara termasuk partikulat. Tujuan penelitian ini adalah untuk menganalisis pengaruh panjang hari kering berturut-turut dengan fluktuasi konsentrasi Particulate Matter (PM) khususnya di wilayah Jakarta. Data pengukuran hujan harian dan konsentrasi partikulat dari 5 stasiun di Jakarta tahun 2019-2023 digunakan sebagai input untuk menganalisis karakteristik spasial dan temporal CDD dan partikulat. Hasil penelitian menunjukkan bahwa nilai CDD dan PM berbanding lurus tertinggi pada periode transisi musim (Maret-April-Mei) dengan korelasi mencapai 0,735 untuk PM10 dan 0,828 untuk PM2.5. Tren spasial bulanan dari tahun 2019-2023 menunjukkan tren positif CDD dan PM, khususnya di bagian timur Jakarta dengan nilai slope maksimum 0,62 untuk PM10 dan 0,58 untuk PM2.5. Hal ini mengindikasikan bahwa semakin panjang hari tanpa hujan, berkontribusi terhadap peningkatan konsentrasi partikulat di wilayah Jakarta. Dari penelitian ini didapatkan bahwa ketika deret hari kering melebihi 17 hari untuk PM10 dan 21 hari untuk PM2.5, perlu diwaspadai konsentrasi partikulat yang berpotensi melebihi Baku Mutu Udara Ambien 24 jam
In the dry season, air quality is often an important issue, especially in the Jakarta area. The increase in the number of days without rain leads to a reduction in factors that help clean the air. Extreme weather conditions also encourage an increase in the number of consecutive days or known as a series of consecutive dry days (CDD), providing opportunities for the accumulation of pollutants in the air, including particulates. The purpose of this study is to analyze the effect of the length of consecutive dry days with fluctuations in Particulate Matter (PM) concentrations, especially in the Jakarta area. Data on daily rainfall measurements and particulate concentrations from 5 stations in Jakarta in 2019-2023 were used as inputs to analyze the spatial and temporal characteristics of CDD and particulate. The results showed that the values of CDD and PM were directly proportional to the highest in the seasonal transition period (March-April-May) with a correlation reaching 0,735 for PM10 and 0,828 for PM2.5. Monthly spatial trends from 2019-2023 show positive trends in CDD and PM, especially in the eastern part of Jakarta with a maximum slope value of 0,62 for PM10 and 0,58 for PM2.5. This indicates that the longer the day without rain can contribute to the increase in particulate concentration in the Jakarta area. The study also found that when the series of dry days exceeds 17 days for PM10 and 21 days for PM2.5, it is necessary to be aware of particulate concentrations that have the potential to exceed the 24-hour Ambient Air Quality Standard.
