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.

Abstract

The increase in greenhouse gases in the form of CO2 gas as vehicle exhaust emissions contributes to climate change. Technological approaches and alternative fuels continue to reduce fuel consumption, but this is not enough. Another method is to use eco-drive behavior, one of which is related to replacing the air filter. This study is purposed to provide guidelines for motorized vehicles operating in selected areas in Lampung Province in the behavior of eco-driving. The results of the fuel consumption test using the full-to-full method found that at each filter distance (8,000 km, 12000, and 16,000 km), vehicles operating in Mesuji with the highest deficiency, followed by Tanjung Bintang and Krui areas. In line with eco-drive behavior, for vehicles operating in Mesuji, the air filter replacement period must be faster than the other two areas, followed by Tanjung Bintang and Krui.
