Abstract

The amount of tobacco waste produced by the cigarette industry reaches 20 tons/day has the potential to pollute the environment if it is not processed first. Tobacco waste content is dangerous because there is heavy Arsenic metal that not in accordance with environmental quality standards, which is 24.19 ppm. Therefore, further technological and waste management approaches need to be taken to become a product that is beneficial and safe for the environment. The processing that can be done is to convert tobacco waste into biochar (Bio-Charcoal) using a Torefication equipment. In the Torefication process there are factors that influence, including temperature and time treatment. Determination of the right temperature and time will determine the quality of biochar produced. The purpose of this reseach was to determine the optimal temperature and time in achieving the best performance of Torefication equipment in the biochar production process from tobacco waste. Changing variables used were temperature (400oC, 450oC, 500oC, 550oC and 600oC) and time (30 minutes, 35 minutes, 40 minutes). The research parameters are % yield, missing components and equipment performance. The result of this reseach showed that the highest and lowest of % yield is 58.37% and 26.27%, the highest and lowest missing components are 73.73% and 41.63% and the highest and lowest equipment performance is 58.2 g/(jam.m) and 19.7 g/(jam.m). Based on statistical analysis the optimal temperature and time is at 450oC and 30 minutes.

Abstract

In the implementation of the siphon system it is used to prevent failure of rising groundwater levels that flow in the highlands including mountain slopes. The siphon system experiences greater drop pressure along with the increase in the height of the siphon, which should have higher pressure with a constant flow and an increase in the height of the siphon to achieve greater siphon system efficiency. To find out the value of pressure drop and the cause of the pressure drop on the siphon system, three methods are used, namely theoretical calculation, simulation of CFD ANSYS and actual measurements using pressure gauge water of bordoun type analogous with variations of valve opening 100% full opened, 66,67% opened, and 33,33% opened and the heights of the siphon are 1 meter, 1,5 meters and 2 meters. From the results of the three methods, the average water flow rate varies based on the height of siphon 1 meter, 1,5 meters and 2 meters is 0,0000854 m3/s to 0,0002716 m3/s and the average pressure of 111.736,7 N/m2 to 88.899,57 N/m2. While the average value of siphon based on variations in valve openings with the same height of siphon is obtained 83.939,634 N/m2 to 130.400,615 N/m2. In addition, an error value between theoretical calculation and CFD simulation of 0,03% to 1,18% and error of the between theoretical calculations and actual measurements is 0,08% to 1,10%.
