research design one group pretest and posttest design. Samples were 19 eighth
grade students MTsN Meureudu school year 2013/2014. Data collected by pretest
and posttest to determine the effect of the application of PBL models and
observation sheets to determine the feasibility of learning. The results showed
that affects the application of PBL model of PPP and understanding the concept
of chemical substances in food MTsN Meureudu eighth grade students. The
influence can be seen from the results of hypothesis testing, the value is
significantly smaller than α (0.05). In addition, the ability of a class VIII
student representation MTsN Meureudu after application of PBL models on
chemical substances in food material for the better. The ability of the student
representation on enactive is 74%, 63% iconic, and symbolic 68%.
