The influence of solar tunnel dryer on the quality of karupuak jangek (case study: Aulia MSME in Jorong Aro Kandikia, Tilatang Kamang Agam Regency)

This study aimed to determine the influence of drying time on the quality of karupuak jangek with solar tunnel dryer to protein content, fat content, texture test and organoleptic test. The raw material of this research was cowhide obtained from Animal Slaughterhouse in Bukittinggi, by using 50 kg of Simmental Crossbreed, aged 2 years. The research method used Completely Randomized Design consisting of 4 treatments. The treatments were drying time A (1 day), B (2 days), C (3 days), D (4 days). The results showed that the influence of drying time on quality of karupuak jangek with solar tunnel dryer on 3 days gave best result of protein content of 58.88%, fat content of 13.69%, texture test with average 210.92 N/cm², a colour organoleptic test 2.06, flavour 2.02 and texture 2.12 showed quite like.
