Abstract
Jeruk pamelo mengandung senyawa antioksidan, antihiperlipidemik, antidiabetik, protein, kalsium dan senyawa bermanfaat lainnya. Indonesia memiliki dua musim, yakni musim penghujan dan musim kemarau. Musim dan ketersediaan air mempengaruhi ketersediaan hara tanaman dan kualitas buah yang dihasilkan. Tujuan dari penelitian ini adalah mengkaji perbedaan kualitas buah pamelo yang dipanen pada dua musim, yakni musim penghujan dan musim kemarau. Penelitian ini dilaksanakan pada bulan Oktober 2018 sampai September 2019 menggunakan rancangan acak lengkap (RAL) 1 faktor yaitu musim. Bahan penelitian menggunakan kultivar Adas Duku yang buahnya dipanen pada musim penghujan dan kemarau. Pengamatan lingkungan dilakukan pada suhu, relative humidity (RH) dan curah hujan. Peubah yang diamati meliputi diameter buah panen secara membujur dan melintang (cm), bobot buah panen (g), tebal kulit buah (cm), jumlah biji (biji), bagian dapat dimakan (BDD) (%), padatan terlarut total (PTT) dalam satuan ºBrix, asam tertitrasi total (ATT) dalam satuan %, rasio PTT/ATT, Vitamin C mg/100 mL dan IC50 dalam %. Buah panen yang diperoleh berukuran lebih besar pada musim penghujan dibandingkan musim kemarau namun buah yang dipanen kemarau memiliki PTT, ATT dan kapasitas antioksidan yang lebih tinggi daripada buah yang dipanen musim penghujan.
