Abstract

AbstrakTujuan Penelitian ini yaitu untukmendapatkan laju pengeringan kentang kering yang memiliki kualitas warna dan kadar air terbaik dengan perlakuan suhu dan ukuran kentang yang diujikan. Pengeringan ini menggunakan Tunnel Dehydrator untuk mendapatkan kombinasi perlakuan suhu dan ukuran kentang dengan analisis warna dan kadar air untuk mendapatkan perlakuan terbaik dan laju pengeringan. Hasil penelitian ini mendapatkanlaju pengeringan y = -0.013x + 5.0433 dan koefisien determinasi (R2) sebesar 0.9539 atau 95.39% dengan Perlakuan pengeringan terbaik pada suhu 70˚C dengan ketebalan kentang 1 x 1 x 1 cm,rendemen 14.1 %, kadar air 10.26% dan nilai chroma 23.35(baik sekali) Kata Kunci ; Laju pengeringan, Kentang Kering, Dehydrated Potatoes, Tunnel Dehydrator AbstractThe purpose of this study is to obtain the drying rate of dry potatoes that have the best color quality and moisture content by treating the temperature and size of the potatoes tested. This drying uses a Tunnel Dehydrator to get a combination of temperature and size treatment of potatoes by color analysis and water content to get the best treatment and drying rate. The results of this study get the drying rate y = -0.013x + 5.0433 and the coefficient of determination (R2) of 0.9539 or 95.39% with the best drying treatment at a temperature of 70˚C with potato thickness 1 x 1 x 1 cm, yield 14.1%, moisture content 10.26 % and chroma value 23.35 (very good) Keyword; Drying rate, Dry Potatoes, Dehydrated Potatoes, Tunnel Dehydrator
