Kulit putih semangka diekstraksi dengan metode infusa dan dilanjutkan pengentalan dengan destilasi vakum. Penyari yang digunakan aquadest. Infusa kulit putih semangka dibuat dalam sediaan granul effervescent dengan konsentrasi 10% tiap formula dan diformulasikan dengan kombinasi sumber asam dari asam sitrat dan asam tartrat dengan konsentrasi 30%, 31% dan 32%. Setelah dilakukan pembuatan, dilanjutkan uji mutu fisik meliputi kecepatan alir, sudut diam, waktu larut, pH, ketinggian buih, uji tanggapan rasa, bau dan kejernihan. Dari hasil uji fisik didapat rata-rata ketiga formula memiliki kecepatan alir kisaran 7,27-9,21 detik yang memenuhi syarat, sudut diam 11,30°-15,94° menyatakan baik, waktu larut yang memenuhi syarat yakni 2 menit 16 detik-2 menit 25 detik, ketinggian buih yang meningkat kisaran 5-9,5 cm dan pH dari formula I sampai III mengalami penurunan 6,17-5,41.
