Abstrak gajah sumatera (elephas maximus sumatranus) merupakan satwa yang dilindungi dan berada dalam status terancam punah. salah satu aspek penting dalam upaya konservasi adalah memahami kondisi fisiologisnya, termasuk kadar hormon progesteron yang berperan dalam sistem reproduksi. penelitian ini bertujuan untuk mengetahui kadar progesteron plasma pada gajah sumatera betina di lima conservation response unit (cru) di provinsi aceh serta hubungannya dengan faktor cuaca, yaitu suhu, kelembaban, dan curah hujan. sebanyak 48 sampel plasma dari 16 ekor gajah betina dikoleksi dari cru alue kuyun, cot girek, das peusangan, sampoinet, dan trumon. pengukuran kadar progesteron dilakukan menggunakan metode elisa, sedangkan data cuaca diperoleh dari satelit nasa. hasil analisis menunjukkan bahwa terdapat perbedaan signifikan kadar progesteron antar cru (p

ABSTRACT The Sumatran elephant (Elephas maximus sumatranus) is a protected species currently classified as critically endangered. One of the key aspects of conservation efforts is understanding its physiological status, including progesterone levels, which play a crucial role in the reproductive system. This study aimed to determine the plasma progesterone levels in female Sumatran elephants at five Conservation Response Units (CRUs) in Aceh Province and to assess their relationship with weather factors, namely temperature, humidity, and rainfall. A total of 48 plasma samples were collected from 16 female elephants at CRU Alue Kuyun, Cot Girek, DAS Peusangan, Sampoinet, and Trumon. Progesterone levels were measured using the ELISA, while weather data were obtained from the NASA POWER satellite. The results showed a significant difference in progesterone levels among the CRUs (p
