Abstract This research aims to know the influence of contextual teaching and learning (CTL) combined with peer tutoring toward learning achievement on human digestive system concept. This research was conducted at one of State Senior High School in South Tangerang in the academic year of 2016/2017. The research method was quasi experiment with nonequivalent pretest-postest control group design. The sample was taken by simple random sampling. The total of the sampels were 86 students which consisted of 44 students as a controlled group and 42 students as an experimental group. The research instrument was objective test which consisted of 25 multiple choice items of each pretest and posttest. The research also used observation sheets for teacher and students activity. The result of data analysis using t-test on the two groups show that the value of tcount was 2.40 and ttable was 1.99 on significant level α = 0,05, so that tcount > ttable.. This result indicated that there was influence of contextual teaching and learning (CTL) combined with peer tutoring toward learning achievement on human digestive system concept.Keywords: Contextual Teaching and Learning, Peer Tutoring, Learning Achievement, Human Digestive System

This study aims to improve the learning outcomes with the use of Project Based Learning (PjBL) model on the concept of environmental pollution. The research method used was Classroom-based Action Research (CAR) with data collection techniques in the form of learning result test, observation sheet, and field notes. This research was a research conducted in two cycles. Each cycle consisted of planning, implementing, observing, and reflecting. The subjects of the study were the students of class X MIPA 1 SMAN 9 Tangerang Selatan in academic year 2016/2017 with the number of students was 38. The research instruments used were test and non-test instrument. Instrument test was in the form of multiple choices (30 questions), while the non-test instruments were in the form of observation sheets and field notes. The data analysis technique was by using N-gain test. The result of this research showed that the improvement of learning outcome in the concept of environmental pollution with the use of learning model based learning (PjBL) in each cycle was 47.37% in the cycle I, and 94.73% in the cycle II. The learning activity of the students showed the increase of activity with the use of learning model Project based learning (PjBL) in the cycle which was 72% in cycle I, and 78% in cycle II. The result of N-gain analysis showed the increase of N-gain from pretest to posttest in which the average of N-gain value in cycle was 0.32 in cycle I and 0.53 in cycle II. Thus it can be concluded that there is influence from the application of the model of Project Based Learning (PjBL) to improve student learning outcomes on the concept of environmental pollution.
