Penelitian yang dilakukan ini tentang pemodelan dan eksperimen dengan pengering rak menggunakan pemanas gas memakai produk daun wasabi. Tujuan yang diambil yaitu memperoleh data pengeringan waktu dan suhu. Membuktikan perubahan laju pengeringan terhadap pengaruh waktu dan suhu pengeringan. Mempelajari model lapisan tipis untuk mendapatkan pemodelan kurva pengeringan. Metode penelitian faktor pertama melakukan pengeringan selama 7,5 jam dan faktor kedua menggunakan suhu 60, 80, 100, 120oC. Variabel meliputi kandungan kadar air % (kg/g). Hasil penelitian ini menghasilkan nilai efisiensi energi = meningkat dari 30,9%-35,9%, konsumsi energi = dari 9,07 x103–1,91 x 105 kj/kg, moisture content= dari 2,2 –85,28%, moisture ratio = dari 0,02– 0,98, diffusifitas efektif = dari 2,49 x 10-6-4,11 x 10-6 m2s-1, energi aktivasi = 8,53 kj mol-1. Model Newton suhu 80oC adalah model yang terbaik karena model tersebut memperlihatkan hasil nilai yang sesuai dengan nilai observasi yang tidak terlalu jauh. Pada suhu 80oC memberikan nilai X2 dan RMSE = 0,0230-1,1267, R2 = 0,975. Kata kunci: Daun wasabi, Diffusivitas, Efisiensi, Energi aktivasi, Moisture ratioDownloads
