Evaluasi Efektivitas Kinerja Teknologi Modifikasi Cuaca (Tmc) Terhadap Indeks Kekeringan Dengan Metode Normalized Difference Drought Index (Nddi) (Studi Kasus : Kabupaten Ketapang)
ABSTRACT
This study aims to evaluate the effectiveness of Weather Modification Technology
(WMT) in influencing rainfall, hotspots, burned area, and drought index in
Ketapang Regency, West Kalimantan, over the period 2019–2023. The data utilized
in this study include rainfall data from CHIRPS, hotspot data from NASA’s FIRMS
system, burned area assessed using the Differenced Normalized Burn Ratio (dNBR)
method, and drought index calculated using the Normalized Difference Drought
Index (NDDI) derived from Sentinel-2 satellite imagery. The results indicate that
the implementation of WMT in Ketapang Regency from June 28 to July 10, 2023,
was highly effective in increasing rainfall across all districts (100%), with the
highest increase observed in Simpang Hulu (1.5847). WMT also successfully
reduced hotspots in 17 out of 20 districts (85%); however, it was ineffective in Hulu
Sungai, Matan Hilir Selatan, and Pemahan. Nevertheless, the effectiveness of WMT
in reducing burned area remained limited, with only 6 out of 20 districts (30%)
experiencing a decrease, particularly in Muara Pawan (PLS = 0.17) and Matan
Hilir Utara (PLS = 0.23), whereas Air Upas (PLS = 10.33) and Hulu Sungai (PLS
= 5.04) recorded an increase in burned area. Additionally, the drought index
(NDDI) decreased in 14 districts (70%), most notably in Hulu Sungai (from 0.0670
to 0.0089), but increased in Sungai Laur and Pemahan. Therefore, further
evaluation of TMC implementation strategies is required to optimize its
effectiveness and ensure a more uniform impact across Ketapang Regency.
