Abstract

installation of Groundstrap on spark plug wires as grounding spark plug wires so that the fire voltage from the coil will focus on the spark plugs. The increase in power and torque occurs because the groundstrap is a type of Ignition Booster whose function is to stabilize the electric current produced by the coil so that the spark plugs can be bigger and more stable, remove stray frequencies or indeterminate voltages from the coil, focus and narrow the current, so that it becomes a firing point towards the spark plug for use as a combustion flame. A steady current produces a good fire, so that the combustion explosion is complete. The method used in this study is the experimental method (direct trial) by making a Groundstrap circuit to determine power and torque in a motorcycle gasoline engine using a Dynotest tool for adding Groundstrap to spark plug wires. In this study using copper wire with a diameter of 0.6 mm and there were 3 variables for the number of turns of the groundstrap wire, namely 60 turns, 90 turns, and 120 turns. In 2008 there was an increase in general, the maximum power and torque yields for standard conditions were 8.3 HP and 8.79 NM, the test on winding 120 experienced the most significant increase of 1.7 HP from standard conditions to 10.0 HP and the torque reaches 3.95 NM from standard conditions to 12.74 NM Keywords: Groundstrap, Copper Wire Coil, Power and Torque

Abstract

Abstract The combustion of fuel inside the combustion chamber takes place as an explosion. This process occurs very quickly and makes a very loud or noisy sound. The function of the muffler is as a silencer and regulates the flow direction of combustion gases to flow regularly. The construction of the free flow exhaust is an exhaust without barriers with relatively wasteful fuel consumption, both working on engines with high revs. Previous researchers replaced the exhaust with a size of tenths of a centimeter of a meter, while in this final project used a fifth of a centimeter. The goal to be achieved by the author in writing this final project is to find out the use of free flow exhaust on power and torque on Yamaha Byson 150cc motorcycles. This final project is carried out by the method of taking test data from the dynotest, using the dynotester tool. The test results are the influence of free flow exhaust measuring 25 cm, 30 cm and standard exhaust, resulting in the most optimal increase in power and torque on a 30 cm free flow exhaust with maximum power data of 13.1 HP at 6750 RPM, and maximum torque reaching 15.35 Nm at 4500 RPM, this is due to the influence of silencer length and without any obstacles, namely the catalic converter which makes the vehicle's breath longer so that it can get peak power at engine speed higher ones.

Abstract

This study examined roles of iron oxide/porous carbon material (Fe/C) for removing metronidazole in simulated wastewater by adsorption and then followed by a degradation using advanced oxidation process (H2O2, O3 and combination of H2O2/O3). Fe/C was produced by an impregnation of iron oxide precursors during resorcinol-formaldehyde synthesis followed by pyrolysis at 800 °C. For comparison, blank carbon (without iron loading) was also synthesized. The properties of porous carbon were investigated by SEM-EDX and N2-sorption analyzer. Blank carbon and Fe/C featured the specific surface area of 755 m2g-1 and 394 m2g-1, respectively. The loading of iron oxide altered the pore structures of material. The adsorption isotherm data were followed by the Langmuir isotherm model with metronidazole uptake up to 46.07 mg g-1 and 39.97 mg g-1 at 30oC by Fe/C and blank carbon. The degradation study was then carried out with catalyst dosage of 0.1 g/100 mL solution and 120 min reaction time at 30 oC. It is noticeably that, the degradation of metronidazole was better when a combination of H2O2/O3 was employed, compared with an individual of H2O2 or O3. Regarding the stability, Fe/C maintained its high activity upon four consecutive runs.
