Abstract

The  purpose  of  this  research  is  to  know  the  effectiveness  of  inquiry  5e  learning cycle  model  based  on  ICT  on  learning  outcomes  and  students?  activity  in  teaching automotive chassis in class XII SMK Pancasila in 2012/2013 academic year. Related to the objective of the research, the research used experimental method. The  research  design  used  is  Quasi-  Experimental  Design  with  Pretest-  Posttest  and Control Group. The total number of population is 120 students coming from four classes. The  sampling  of  the  research  is  cluster  random  sampling.  From  the  population,  two classes/  clusters  were  taken  randomly  as  the  sample  so  there  are  two  classes  in  this research, experimental and control groups. Experimental group used inquiry 5e learning cycle model based on ICT, Control group used lecture model based on ICT. Technique  of the data collection consist of test and obsrvation letter.The data are analyzed by using t-test formula (t-test for independent sample). In this case, data which are analyzed are pre-test and post-test scores of the two groups. The result of t-test in  post-test computation shows that t observation (t0) is 3.73. Value tt with degree of freedom 48 of t table (tt) = 2.00. In this case, to = 3.73 is higher than tt = 2.00 (to  >   tt).  From  the  result,  there  are  significant  difference  learning  outcomes  between using inquiry 5e learning cycle model based on ICT and by using lecture based on ICT. Observation  result  from  observer  concluded,  there  are  significant  difference  on  the students? activity of chassis automotive between the students? taught by using inquiry 5e learning cycle model based on ICT and those taught by using lecture based on ICT. The experimental group show that students? activity better than control group.Based on the research finding above, it can be concluded that Inquiry 5e Learning Cycle  Model  Based  on  ICT  is  effective  to  learning  outcomes  and  students?  activity  in teaching automotive chassis in class XII SMK Pancasila in 2012/2013 academic year.

This  research  is  written  to  achieve  some  objectives  as  follows:  (1)  find  out  the alteration  of  ignition  timingtoward  torque  and  power  on  110  cc  Vega  R  motorcycle  year  of 2008. (2) find out the amount of torque and power  on 110 cc Vega R motorcycle year of 2008 after setting up the ignition timing.This  research  used  descriptive  quantitative  method.  The  sample  used  in  this  study  is 110 cc Vega R motorcycle year of 2008, engine numbered MH34D70028J737691. The data are obtainedfrom  the  amount  of  torque  and  power  by  using  premium  fuel  in  a  standard  ignition angle  (100BTDC/  Before  Top  Dead  Centre)  and  using  LPG  gas  fuel  performed  on  standard ignition angle (100BTDC), advanced ignition angle (130 BTDC) and backward ignition angle (70BTDC). Based on the results of this study, it can be concluded that: (1) There are differences in torque and power on 110 cc Vega R motorcycle Year of 2008 using LPG in a standard ignition angle (100BTDC), advanced ignition timing (130BTDC) and the ignition timing backdated (70BTDC).  (2)  The  torque  producedbythe  motorcycleusingLPG  gas  fuel  inadvancedignition timing(130BTDC)  is higherthan theothervariationsignition timing, that is 7.31 Nm at 6088 rpm engine speed. Torque dropped 1.34 Nm of the resulting torque by motorcycles using premium fuel  in  standard  ignition  timing  is  8.65  Nm  at  5337  rpm  engine  speed,  (3)  The  power  is produced  by  the  motorcycle  using  LPG  gas  fuel  in  advanced  ignition  timing  (130BTDC)  is higher than the other variations ignition timing, that is 6,9 HP in 7591 rpm engine speed.  The power  dropped  0.9  HP  of  the  resulting  power  by  motorcycles  using  premium  fuel  in  ignition time standard of 7.8 HP at 7344 rpm engine speed. (4) Time optimal ignition in 110 cc Vega R motorcycle Year of 2008 using LPG gas fuel is 130BTDC or advanced ignition timing. (5) The effective  engine  speed  of  110  cc  Vega  R  motorcycleyear  of  2008  that  used  LPG  gas  fuel  in advanced ignition timing is 6000 rpm up to 8000 rpm

Abstract

The purpose of this study are investigate effect of usage booster coil,  adding methanol in premium and interaction at  1500 rpm, 2500 rpm, 3500 rpm and 4500 rpm, to low CO and HC emissions on Yamaha Mio Sporty 2007. Component ware used for data analysis includes: ignition system (standard coil and installation booster coil), addition methanol (10% (M10), 20% (M20), 30% (M30) and 40% (M40)), variations of rotation engine speed (1500 rpm, 2500 rpm, 3500 rpm and 4500 rpm), and exhaust emissions (CO and HC). Based on the results of research at 1500 rpm, 2500 rpm, 3500 rpm, 4500 rpm, We can concluded that usage booster coil, addition methanol in premium and interaction can affect CO and HC emissions, so it tends to fall.
