Effects of Fuel Type and Fuel Delivery System on Pollutant Emissions of Pride and Samand Vehicles

This research was aimed to study the effect of the type of fuel delivery system (petrol, dedicated or bifuel), the type of consumed fuel (petrol or gas), the portion of consumed fuel and also the duration of dual-fuelling in producing carbon monoxide, carbon dioxide and unburned hydrocarbons from Pride and Samand. According to research objectives, data gathering from 2000 vehicles has been done by visiting Hafiz Vehicle Inspection Center every day for 2 months. The results of this survey indicated that although there is no significant difference between various fuel delivery systems in terms of producing the carbon monoxide, carbon dioxide and unburned hydrocarbons by Samand, considering the emission amount of carbon dioxide, the engine performance of Pride in bifuel and dedicated state in GTXI and 132 types is more unsatisfactory than that of petrol state by 0.3 and 0.4%, respectively. On the other hand, consuming natural gas increases the amount of carbon monoxide emission in dual- fuel Pride by 0.18% and decreases that in dual-fuel Samand by 1.2%, which signifies the better design of Samand in terms of fuel pumps, used kit type and other engine parts to use this alternative fuel compared to Pride. Since the portion of consumed fuel and also duration of dual-fuelling does not have a significant effect on the amount of output pollutants from the studied vehicles, it can be claimed that the output substances from the vehicle exhaust are more related to the vehicle’s condition than the fuel type

Edukasi Mengenai Kesetaraan Gender di SMPN 01 Dumai Kota Demi Mencegah Diskriminasi Gender di Lingkungan Sekolah

One of the problems that occurs in the social order of society is gender inequality or gender discrimination. In fact, even though gender equality continues to be advocated, gender discrimination still continues to occur. Including in the educational sphere, especially the school environment, normalized gender discrimination still occurs. This is considered normal because middle school teenagers have little knowledge of gender equality. So the Riau University real work lecture team wants to provide education about gender equality with the main target being teenagers, namely students at SMPN 01 Dumai City to prevent gender discrimination in the school environment. With interactive socialization and discussion methods, it was assessed that the students' knowledge and level of analysis regarding gender had increased so that the objectives of implementing the activity had been achieved.
