| dc.description.abstract | Peningkatan aktivitas transportasi di Kota Bogor berpotensi meningkatkan
konsentrasi PM2.5 yang dipengaruhi oleh kondisi meteorologi, terutama angin dan
curah hujan. Penelitian ini bertujuan menganalisis fluktuasi temporal PM2.5,
hubungannya dengan volume kendaraan dan angin, serta mengestimasi kontribusi
sumber emisi menggunakan metode Hybrid Single-Particle Lagrangian Integrated
Trajectory Concentration Weighted Trajectory (HYSPLIT-CWT). Data yang
digunakan adalah konsentrasi PM2.5 dan parameter meteorologi dari CCROM
SEAP IPB University Kampus IPB Baranangsiang serta data volume kendaraan
tahun 2024 di Gerbang Tol Baranangsiang dari PT Jasa Marga. Data dianalisis
menggunakan analisis fluktuasi temporal, wind rose, polar plot, analisis korelasi,
dan HYSPLIT-CWT. Hasil analisis memberi gambaran bahwa pada tahun 2024
konsentrasi PM2.5 rata-rata sebesar 20 µg/m³, dengan nilai tertinggi 59 µg/m³ pada
bulan Agustus. Konsentrasi meningkat pada musim kemarau, bersamaan dengan
curah hujan rendah dan kecepatan angin lemah. Volume kendaraan menunjukkan
pola mingguan meningkat pada menjelang akhir pekan (Jum’at dan Sabtu) yang
sejalan peningkatan PM2.5, dengan nilai koefisien determinasi sebesar R² = 0,4936.
Kecepatan angin menunjukkan korelasi negatif terhadap konsentrasi PM2.5, dengan
korelasi terkuat pada musim hujan (r = -0,61) dan terlemah pada musim kemarau
(r = -0,06). Analisis polar plot dan HYSPLIT-CWT mengidentifikasi arah angin
dominan serta menunjukkan adanya kontribusi sumber emisi lokal dan dari wilayah
lain terhadap PM2.5. yang terukur di Baranangsiang. | |
| dc.description.abstract | Increased transportation activity in Bogor City has the potential to raise PM2.5
concentrations, which are also influenced by meteorological conditions,
particularly wind and rainfall. This study aims to analyze the temporal fluctuation
of PM2.5, its relationship with vehicle volume and wind, and to estimate the
contribution of emission sources using the Hybrid Single-Particle Lagrangian
Integrated Trajectory Concentration Weighted Trajectory (HYSPLIT-CWT)
method. The data used consist of PM2.5 concentrations and meteorological
parameters from CCROM-SEAP, IPB University, Baranangsiang Campus, as well
as 2024 vehicle volume data from the Baranangsiang Toll Gate provided by PT Jasa
Marga. The data were analyzed using temporal fluctuation analysis, wind rose,
polar plot, correlation analysis, and HYSPLIT-CWT. The results show that in 2024,
the average PM2.5 concentration was 20 µg/m³, with the highest value of 59 µg/m³
recorded in August. Concentrations increased during the dry season, coinciding
with low rainfall and weak wind speed. Vehicle volume exhibited a weekly pattern
that increased toward the weekend (Friday and Saturday), consistent with the rise
in PM2.5, with a coefficient of determination of R² = 0.4936. Wind speed showed a
negative correlation with PM2.5 concentration, with the strongest correlation
observed during the rainy season (r = -0.61) and the weakest during the dry season
(r = -0.06). Polar plot analysis and HYSPLIT-CWT identified the dominant wind
directions and revealed contributions from both local and regional emission sources
to the PM2.5 concentrations measured at Baranangsiang. | |
