Abstract
Cost production efficiency through modified tunnel driyer by using the economizer so that the cost of fuel component eliminated. This study aimed to determine the performance of modified tunnel driyer associated with the quality of the product produced related to achived drying rate . From 3 (three) experiments conducted with variations in the hot air flow velocity of 0.5 m / sec, 0.7 m / sec, and 0.9 m / sec, it was found that only the first experiment occurred condensation and the resulting drying product was declared NG . From the results of the hypothesis independent sample t-test concluded the level of dryness of the results of the 3rd experimental product is better than the results of the 2nd experimental product. Thus, setting a hot air flow rate of 9 m / sec produces the most optimal modified dryer performance.

Summary
Kemas Muhammat Abdul Fatah* Program Studi Teknik Mesin, Universitas Sang Bumi Ruwa Jurai Jln. Imam Bonjol No.486. Efisiensi biaya produksi melalui modifikasi oven pengering dengan memanfaatkan economizer sebagai sumber panas proses pengeringan, sehingga komponen biaya bahan bakar solar dihilangkan. Penelitian ini ditujukan untuk mengetahui unjuk kerja oven pengering hasil modifikasi yang dikaitkan dengan mutu produk yang dihasilkan yang diukur dari tingkat kekeringan yang dicapai. Dari 3 (tiga) eksperimen yang dilakukan dengan variasi pada kecepatan aliran udara panas yaitu 0.5 m/dtk, 0,7 m/dtk, dan 0,9 m/dtk, ditemukan bahwa pada hanya eksperimen pertama terjadi kondensasi dan produk hasil pengeringan dinyatakan NG. Dari hasil hipotesis independent sample t-test menyimpulkan tingkat kekeringan produk hasil eksperimen ketiga lebih baik dari produk hasil eksperimen kedua. Sehingga, setting laju aliran udara panas sebesar 9 m/dtk menghasilkan unjuk kerja oven pengering hasil modifikasi yang paling optimal
