Abstract

This research was carried out to find out the dynamics of climate change in the Bangka Belitung Islands, by utilizing BMKG observer station data at Depati Meteorological Station, starting in 1981 until 2022 that the official obtained from the BMKG website online. This research was conducted at the Education laboratory of FKIP Physics University of Sriwijaya. The research method used is secondary data research with a quantitative approach. Data analysis was used using the RClimDex application with the Expert Team on Climate Change Detection and Indices (ETCCDI) rules. Trend analysis was carried out with non-pithelmetry statistical tests Man-Kendall and Sens tests. The temperature indexes experience significant trends, which indicates that the longer the temperature in the Bangka Belitung Islands will increase.

Abstract

Penelitian ini dilakukan untuk mengetahui dinamika trend curah hujan ektrem di provinsi Kepulauan Bangka Belitung sebagai indikasi dari dampak pemanasan global. data  yang digunakan bersumber dari Stasiun Meteorologi Depati Amir dari periode 1981 sampai tahun 2022, yang diperoleh secara resmi dari situs web BMKG online. Penelitian ini dilakukan di laboratorium Pendidikan Fisika FKIP Universitas Sriwijaya. Metode penelitian yang digunakan adalah penelitian data sekunder dengan pendekatan kuantitatif. Analisis data digunakan menggunakan aplikasi RClimDex dengan aturan Expert Team on Climate Change Detection and Indices (ETCCDI) terkait indikator curah hujan. Analisis tren dilakukan dengan uji statistik non parametrik Man-Kendall dan Sens test. Hasil analisis menunjukkan bahwa indeks-indeks curah hujan ekstrem mengalami tren yang bervariasi secara signifikan selama 40 tahun terakhir, yang menunjukkan adanya dampak perubahan iklim sebagai dampak dari pemanasan global.

Abstract

This study aims to analyze the influence of sea surface temperature (SST), outgoing longwave radiation (OLR), and the Indian Ocean Dipole (IOD) on rainfall dynamics in the peatlands of East Sumatra’s coast. Data from ERA5 (SST, OLR), BMKG (rainfall), and a calculated IOD index (1982–2024) were analyzed quantitatively using Python and Pearson correlation. Results show SST in the Indian and Pacific Oceans correlates significantly and positively with rainfall (r > 0.6; p < 0.05), confirming the dominant roles of IOD and ENSO. OLR exhibits a strong negative correlation (r < –0.7; p < 0.05), reflecting its inverse relationship with convective activity and rainfall. The IOD index is significantly correlated with rainfall variation, particularly during positive IOD events, which are linked to rainfall deficits and increased peat fire risk. This quantitative analysis provides a basis for predicting rainfall and mitigating peatland fires.
