Abstract

Processing activities of oil palm fruit into CPO produce liquid waste that can pollute the environment, so it is necessary to process liquid waste in palm oil mills. This study aims to design the filtration to overcome the existing pollution in the palm oil mill. The table shows the formation of 3 filter ABC formations has the highest speed of 6.419 m/s. When we place a large meshing hole on the first level, the speed and speed are smaller, this can be seen in the CBA, CBAC and CBACB formations. The meshing formation with a small size in the first position can increase the speed and pressure, we can see this in the ABC, ABCA and ABCAB formations so that the oil palm wastewater filtration process can run smoothly without a decrease in fluid velocity.

Abstract

In a combustion engine, to generate torque, a combustion and compression process is required. Apart from obtaining mechanical energy, the combustion results also produce exhaust emissions, which can result in a polluted environment. This research aims to determine the influence of torque and exhaust gas emission modeling by using variations in the number of filters using simulation software. This research is descriptive and quantitative research with an experimental method. This research uses a Dyno test tool and a Gas Analyzer from this research to find out data from the exhaust that has been varied. The addition of a filter reduces the torque value by 1.7%. The presence of a filter on the catalytic converter has been proven to reduce levels of exhaust emissions that are harmful to the environment (CO, HC). Of the variations in the number of catalytic converters, filter number 2 is the best, producing 9.71 hp with CO emission levels of 1.7% and HC 553 PPM.
