The purpose of this study was to determine the total phenol content and antioxidant activity of Sonneratia alba mangrove fruit dried at 50°C in a cabinet dryer with different extraction times. The method used in this study was exploratory, the data were analyzed descriptively, the treatment used was the extraction time of 5, 10 and 15 minutes in boiling water, the test parameters used were the total phenol content using the Folin-Ciocalteau method and antioxidant activity using the DPPH method (1,1-diphenyl-2-picrylhydrazyl). The results obtained were as follows: the highest total phenol value was found in the 10-minute extraction time treatment, namely 23.7851 mg GAE/g; the strongest antioxidant activity was found in the 10-minute extraction time, namely 5.25 ppm. From the data obtained, it can be concluded that the best treatment is the extraction time in boiling water for 10 minutes.

Tujuan penelitian ini adalah mengetahui kandungan total fenol dan aktivitas antioksidan buah mangrove Sonneratia alba yang dikeringkan pada suhu 50°C di dalam kabinet dryer dengan lama ekstraksi yang berbeda. Metode yang digunakan dalam penelitian ini bersifat eksploratif, data dianalisis secara deskriptif, perlakuan yang digunakan adalah lama ekstraksi 5, 10 dan 15 menit dalam air mendidih, parameter uji yang digunakan adalah kandungan total fenol menggunakan metode Folin-Ciocalteau dan aktivitas antioksidan menggunakan metode DPPH (1,1-difenil-2-pikrilhidrazil). Hasil penelitian yang diperoleh adalah sebagai berikut: nilai total fenol tertinggi ditemukan pada perlakukan lama ekstraksi 10 menit yaitu 23,7851 mg GAE/g; aktivitas antioksidan terkuat ditemukan pada lama ekstraksi 10 menit yaitu 5,25 ppm. Dari data yang diperoleh dapat disimpulkan bahwa perlakuan yang terbaik adalah lama ekstraksi dalam air mendidih selama 10 menit.
