Kampung Muka, terletak di Kelurahan Ancol, Jakarta Utara, menjadi lokasi penelitian karena adanya dugaan risiko kesehatan akibat pajanan PM2,5, seperti yang juga ditemukan di wilayah lain di DKI Jakarta. Studi sebelumnya di Kepulauan Seribu, Jalan Daan Mogot, dan Terminal Kampung Rambutan menunjukkan nilai RQ>1, menandakan potensi bahaya kesehatan akibat polusi udara. Penelitian ini bertujuan mengestimasi risiko kesehatan pada balita yang tinggal di Kampung Muka akibat pajanan PM2,5. Penelitian dilakukan menggunakan desain Analisis Risiko Kesehatan Lingkungan dengan pengukuran di empat titik sampling dan melibatkan 81 responden. Hasil penelitian memperlihatkan bahwa konsentrasi PM2,5 di Kampung Muka, setelah dikonversi menjadi pajanan 24 jam dengan metode Canter, masih di bawah baku mutu yang merujuk pada PP No. 22 Tahun 2021 (≤55 µg/m³), dengan nilai tertinggi sebesar 44,4 µg/m³. Karakterisasi risiko rata-rata realtime dan lifetime menunjukkan RQ1 pada penghitungan pajanan realtime individu, berkisar antara 1,010 hingga 2,257 di beberapa titik. Hasil ini mengindikasikan adanya potensi risiko kesehatan pada kelompok balita meskipun rata-rata konsentrasi PM2,5masih memenuhi standar, sehingga diperlukan pemantauan lanjutan.

Kampung Muka, located in Ancol Sub-district, North Jakarta, was chosen as the study site due to suspected health risks from PM2.5 exposure, similar to findings in other areas of DKI Jakarta. Previous studies conducted in Kepulauan Seribu, Daan Mogot Road, and Kampung Rambutan Terminal reported RQ values greater than 1, indicating potential health hazards from air pollution. This study aimed to estimate health risks among toddlers living in Kampung Muka due to PM2.5 exposure. The research used an Environmental Health Risk Assessment design, with PM2.5 measurements taken at four sampling points and involving 81 respondents. The results showed that PM2.5 concentrations in Kampung Muka, after conversion to 24-hour exposure using the Canter method, remained below the quality standard set by Government Regulation No. 22 of 2021 (≤55 µg/m³), with the highest value recorded at 44.4 µg/m³. Risk characterization for average realtime and lifetime exposure indicated RQ values below 1. However, eight toddlers were found to have individual realtime RQ values greater than 1, ranging from 1.010 to 2.257 at various points. These findings suggest potential health risks among toddlers, even though the average PM2.5 concentration still meets regulatory standards, highlighting the need for continued monitoring.
