Abstract

This study aims to develop e-module based on Problem Based Learning (PBL) on hydrocarbon materials using the Kvisoft Flipbook Maker application. This research is a development research with 4-D development model. The data obtained came from 6 validators (3 material experts and 3 media experts), 4 chemistry teachers and 12 students from four high schools namely SMA Negeri 8 Pekanbaru, SMA Negeri 5 Pekanbaru, SMA Negeri 3 Pekanbaru and SMA IT Al-Fityah Pekanbaru. Data collection techniques used in the form of documentation and questionnaires. The data analysis technique is by calculating the percentage score of the validation assessment and user responses. The results showed that the e-module developed fulfilled very valid criteria with a percentage of 85.39% by material experts and 97.02% by media experts. The results of the chemistry teacher and student response test showed that the e-module developed fulfilled very practical criteria with a percentage of 92.60% by chemistry teachers and 89.60% by students

Abstract

Air pollution gives a negative impact to human health due to pollutants released by motor vehicles. From the several kinds of pollutants generated, CO is one of the most pollutants released by motor vehicles. Lead can contaminate the environment and can poisoning the living organisms. Lead can cause various disorders to the body and also organs such as hematopoietic system, neurological, endocrine, renal, gastrointestinal, hematological, and reproduction. This study aims to analyze the comparison of the levels of lead (Pb) in fried foods sold on Jalan Sam Ratulangi with fried foods sold on the edge of Jalan Purwodadi, Pekanbaru City. This research is descriptive quantitative. Samples in the form of bakwan which were taken by one trader by using a total sampling of 6 samples. The sample will then be examined quantitatively to determine the level of lead in the sample using the atomic absorption spectrophotometric method. The results of the lead level examination will then be compared with the maximum limit of metal contamination according to the standards set by the Directorate General of Drug and Food Control No. 00.06.1.52.4011 Year 2009 to find out whether the fried foods sold in that location meet the Threshold Value (NAB), and compared using the SPSS t test. The results of the research after analysis using the t test, it is known that the p value is 0.216 when compared with a= 0.05, then p>a, so there is no significant difference between the fried foods sold on Jalan Sam Ratulangi and Purwodadi, Pekanbaru City, all samples exceed The threshold value set by the Regulation of the Director General of Drug and Food Control Number HK.00.06.1.52.4011 of 2009 is 0.25 mg/kg.

Abstract

The aim of this research is to know the effect of CORE (Connecting, Organizing, Reflecting and Extending) learning models to students concept understanding of atomic strukture. This research is quasi experimental research with a nonequivalent control group. The population in the research is class X SMA Negeri 1 Kampar Timur. The samples in the research was X MIPA 2 as an experimental class and class X MIPA 5 as a control class which was determined randomly. The experimental class was treated with the implementation of CORE learning model while the control class with a scientific approach. Data was collected using essay test instruments. The data obtained from test were analyzed descriptively and statistically by the test-t right side. The results of data analysis obtained tcount = 5,63 and ttable = 1,66 with α = 0,05, dk = 74. Tcount > ttable is 5,63 > 1,66 meaning that the implementation of CORE learning model can improve students concept understanding on the subject of atomic structure in the class X MIPA SMA Negeri 1 Kampar Timur. Criteria students concept understanding in the experimental class with an average N-gain of 0,80 while the average N-gain in the control class is 0,69.
