Abstract

The design aims to produce mass cracker production on a homa scale industry that is effective and efficient i order to meet consumption needs. The cutting machine has on a 50cm length of aluminium strip plate, a roll knife made of stainless stell, 1,5mm thick, 45mm diameter, 5mm middle axle hole, with letter L shape support. With 12 knives the roll has a distance of 4cm. Testing on a thick dough of 1-1,5mm width 46cm square with the help of a 10mm thick pvc mattress 50cm wide square using a stopper right and left in the shape of an angle of 3mm thick iron plate the work process of scratching a roll knife into the dough on the mat with a reference to the stopper of longitudinal and transverse movements for effective and efficient results, testing five times gets an average time of 00:49 seconds in the previous test while in the renewable machines it gets an average time of 00:22seconds. So the results of the analysis can be said to be effective and have more efficiency than previous machines.

Abstract

One of the reasons for the air pollution that occurs at this time is the emission of the motorcycle exhaust. According to some sources, the trembesi leaves can absorb the level of exhaust emissions. By making extracts from trembesi leaves and added to the exhaust part of the motorcycle. Because the exhaust part is the last place of discharge of combustion waste from the combustion process that occurs on motorcycles and the result is that when the motorcycle has not been added trembesi leaf extract can produce a level of emission of Nitrogen Oxide (Nox) exhaust gases of 0.21 ppm. While the results are different when already added trembesi leaf extract can produce a level of emission of Nitrogen Oxide (NOx) exhaust gases of 0.16 ppm So it can be concluded that trembesi leaf extract can absorb or reduce the level of emission of Nitrogen Oxides (NOx), and meet the requirements of nitrogen oxide (NOx) exhaust emission levels applied in Indonesia, which is 0.17 for speeds below 1300 rpm.
