Abstract

Sumber pemanas merupakan aspek penting dalam proses pengeringan padi, hal ini bergantung pada analisis temperatur optimal untuk digunakan pada proses pengeringan selanjutnya. Pengeringan padi merupakan proses penurunan kadar air awal padi. Padi pasca panen pada umumnya memiliki kadar air awal sekitar 20% - 26%. Metode pengeringan terdiri dari dua macam, yaitu pengeringan konvensional (dijemur di sinar matahari) dan menggunakan mesin pengering. Pada umumnya, proses pengeringan padi harus mencapai 14%. Percobaan ini menggunakan kapasitas 50 kg dan 100 kg gabah basah. Berdasarkan data yang didapatkan, nilai temperatur yang paling optimal kedua kapasitas ini adalah 600 C. Pada kapasitas 50 kg, pengeringan optimal membutuhkan waktu 36 menit dan 3 detik, dengan hasil kualitas putih dan utuh. Begitu pula pada kapasitas 100 kg yang membutuhkan waktu 1 jam 35 menit dan 20 detik. ======================================================================================================== Heating source is a priority in the rice drying process, it is necessary to analyze the optimal temperature used in the subsequent drying process. Paddy drying is the work to decrease post harvesting paddy moisture. Post harvesting paddy typically has high moisture contents ranging from 20 % - 26 %. There are two kinds of paddy drying method, that are conventional (relaying on the sun) and using dryer. Generally, paddy drying process must reach moisture level at 14% to generate the best quality standard. The methods of this experiment are designing and building, and then doing experiment about the effect of the increasing temperature to decrease moisture contents based on time needed to reach moisture level at 14%. This experiment uses 50 kg and 100 kg of wet rice. Based on the data obtained, the temperature optimum value of both capacities(50 kg and 100 kg) is 600 C. For 50 kg capacity, the optimum drying time is 36 minutes 3 seconds with white and intact quality of rice, as well as the 100 kg capacity, its drying time is 1 hour 35 minutes 20 seconds.
