      Abstract
      Apokad (Persea americana Mill.) menjadi salah satu buah pilihan masyarakat karena memiliki rasa yang enak, kandungan antioksidan tinggi, kaya akan serat, dan nutrisi. Apokad merupakan buah klimakterik dimana proses pemasakannya akan terus berlangsung setelah buah dipanen dari pohon. Salah satu tantangan global yang harus dihadapi petani apokad saat ini adalah menawarkan produk kepada konsumen dengan tingkat kemasakan homogen. Penelitian ini bertujuan mengetahui karakteristik awal buah apokad, menemukan konsentrasi ethephon yang tepat dan efektif untuk mempercepat dan menyeragamkan kemasakan apokad serta mengetahui pengaruhnya terhadap mutu buah. Rancangan penelitian yang digunakan adalah rancangan kelompok lengkap teracak (RKLT) faktor tunggal berupa penambahan ethephon dengan konsentrasi 0, 500, dan 1000 ppm. Parameter yang diamati yaitu kadar air, kelunakan, edible portion, susut bobot, PTT, ATT, vitamin C, diameter, panjang, warna daging dan kulit buah yang diamati hingga 15 hari setelah perlakuan (HSP). Hasil penelitian menunjukkan ethephon dengan konsentrasi 500 ppm dapat mempercepat pemasakan 3 hari lebih cepat dibandingkan dengan perlakuan kontrol, serta dapat mempertahankan mutu lebih lama dibandingkan dengan perlakuan ethephon 1000 ppm sampai dengan 12 HSP.
       
      Avocado (Persea americana Mill.) is one of the people’s choice fruit because it has a good taste, high antioxidant contents, is rich in fiber and nutrients. Avocado is a climacteric fruit where the ripening process will continue after the fruit is harvested from the tree. One of the global challenges that avocado farmers have to face today is offering consumers products with homogeneous ripeness levels. This study objective is to determine the initial characteristics of avocados, obtain the appropriate and effective ethephon concentration to accelerate and uniform avocado ripening as well as determine its effect on fruit quality. The research design used was a single factor randomized complete block design in the form of ethephone concentrations of 0, 500, and 1000 ppm. The parameters observed were moisture content, softness, edible portion, weight loss, TSS, TTA, vitamin C, diameter, length, flesh and skin color of the fruit which were observed up to 15 days after treatment (DAT). The results showed that ethephon with a concentration of 500 ppm could accelerate ripening 3 days faster than the control treatment, and could maintain quality longer than the 1000 ppm ethephon treatment up to 12 DAT.
