Abstract

The research was conducted in August – November 2013. The purpose of this study was to determine the content of heavy metals of Pb, Cu, Zn and Ni in the sediment and its organic matter content in the east coast of Sumatera. The method used was survey method in wich the East coast of Sumatera coastal waters was used as the location of sampling.The results showed that different sediment fraction had different concentration of heavy metals. The sediment fraction of >250 μm had higher concentration than the fraction <63 μm and 63 μm – 250 μm. The concentration of Pb, Cu, Zn and Ni in the sediment were 7.29, 12.91, 8.69 and 14.57 μg/g respectively. Simple linier regression analysis showed of negative corelations for Pb, Cu, and Zn. and positive corelations for Ni with the content of organic matter in the sediment. The Pb, Cu, Zn and Ni concentrations were still below the value of ERL and ERM.Keywords : heavy metals, sediment, organic matter, east coast of Sumatera

Abstract

Abstrak The objectives of this study was to find out whether or not there was a significant effect of the using Think-Pair and Share technique at seventh grade students’ reading comprehension of Junior High School Satu Atap Bertam. This research was conducted at first grade students of Junior high school Satu Atap Bertam. This school is located in Muaro Jambi, there are two classes of seventh grade students, and this school uses school based curriculum. In conducting the research, the writer used the experimental research, and the design of the experimental research was a quasi-experimental research. The result of the research found two things: First, the writer has computed the two means score by using t -test formula; the value of t-test was higher than the value of t-table. It indicated that there was a different on the students’ reading comprehension that was taught by using Think Pair and Share technique. Second, the result of the analysis indicated there was a significant difference between the students’ reading comprehension taught by using Think Pair and Share technique and those who were not. Keywords: Think-Pair and share technique; reading comprehension

Abstract

The objectives of this study were to determine whether or not there was a significant effect of using REDW ( Read, Examine, Decide, Write ) strategy on reading comprehension and to know the significant difference of reading comprehension between students who are taught by using REDW (Read, Examine, Decide, Write) strategy and those who are not . The study was conducted at Islamic Junior High School Tarbiyah Islamiyah Jambi. The population in this study were all eighth graders, each class consisted of less than 30 students. The researcher used REDW strategy in class 8B as the experimental class and class 8A used conventional method as control class. This research used quantitative – experimental approach. The design of study was quasi-experimental design, it was the pretest-posttest non- equivalent group design. The data was collected by a test as research instruments, there were two test: pre-test and posttest. From the results of the test, the independent t-test calculation in posttest score in both groups showed that the significant value was higher than level of significance (0.870 > 0.05). It indicated that there was the significant difference between experimental and control group. Moreover, the paired t-test calculation showed the result of paired sample t-test (5.949 < 0.05) in which there was a significant effect of using REDW strategy on students reading comprehension.
