Abstract
Climate change is a global problem that has a major impact in Indonesia, including in Tangerang Regency. Changes in rainfall and temperature patterns due to climate change have the potential to cause drought, a condition of gradual water shortages that impact the agricultural, economic, and social sectors of society. This study aims to predict areas that are potentially experiencing drought in Tangerang Regency through analysis of rainfall and temperature data. The data used are secondary data in the form of rainfall and air temperature from the Class III Budiarto-Curug Meteorological Station and drought data from the Tangerang Regency Regional Disaster Management Agency (BPBD). The analysis was carried out temporally and spatially using the Standardized Precipitation Evapotranspiration Index (SPEI) and SPI as a comparison. The results of the study showed that the SPI index was unable to clearly indicate drought because most areas were in the normal category. On the other hand, the SPEI index showed significant drought spatially and temporally. Drought began to be identified in March and peaked in June 2024, with extreme SPEI values between -2.74 and -2.36. The affected areas include sub-districts in the western and southern parts of Tangerang Regency, such as Panongan, Curug, Jambe, Legok, Cisauk, Kelapa Dua, and Pagedangan, and extend to Sindangjaya, Cisoka, and Solear. This study shows that the combination of rainfall and temperature data through the SPEI index can provide a more accurate picture of drought and can be used as a basis for drought mitigation and water resource management.

| Additional Information: | Perubahan iklim merupakan permasalahan global yang berdampak besar di Indonesia, termasuk di Kabupaten Tangerang. Perubahan pola curah hujan dan suhu akibat perubahan iklim berpotensi menimbulkan kekeringan yaitu kondisi kekurangan air secara bertahap yang berdampak pada sektor pertanian, ekonomi, dan sosial masyarakat. Penelitian ini bertujuan untuk meramalkan wilayah-wilayah yang berpotensi mengalami kekeringan di Kabupaten Tangerang melalui analisis data curah hujan dan suhu. Data yang digunakan merupakan data sekunder berupa curah hujan dan suhu udara dari Stasiun Meteorologi Kelas III Budiarto–Curug serta data kekeringan dari Badan Penanggulangan Bencana Daerah (BPBD) Kabupaten Tangerang. Analisis dilakukan secara temporal dan spasial menggunakan indeks Standardized Precipitation Evapotranspiration Index (SPEI) dan SPI sebagai pembanding. Hasil penelitian menunjukkan bahwa indeks SPI tidak mampu menunjukkan kekeringan secara jelas karena sebagian besar wilayah berada dalam kategori normal. Sebaliknya, indeks SPEI menunjukkan kekeringan yang signifikan secara spasial dan temporal. Kekeringan mulai teridentifikasi pada Maret dan mencapai puncaknya pada Juni 2024, dengan nilai SPEI ekstrem antara -2.74 hingga -2.36. Wilayah terdampak meliputi kecamatan di bagian barat dan selatan Kabupaten Tangerang, seperti Panongan, Curug, Jambe, Legok, Cisauk, Kelapa Dua, dan Pagedangan, serta meluas ke Sindangjaya, Cisoka, dan Solear. Penelitian ini menunjukkan bahwa kombinasi data curah hujan dan suhu melalui indeks SPEI mampu memberikan gambaran kekeringan yang lebih akurat dan dapat dijadikan dasar mitigasi kekeringan dan pengelolaan sumber daya air. | |||||||||
