Abstract: The aim of  this research was to increase critical thinking skill on the subject digestion system grade VIII junior high school. This research was conducted at the Laboratory of Biology Department of the University of Riau PMIPA FKIP and SMPN 23 Pekanbaru in March to September 2016. The research is a research development by using ADDIE model of integration to the stage of development. There are 5 LKS developed. Instruments of data collection in this study is the validation sheet LKS, and questionnaire responses of learners. After LKS developed, validated by 4 validator then the tests I in the 4th semester 20 students of biology education FKIP UR, and a second trial on 20 students of Class VIII SMPN 23 Pekanbaru. The tests showed the average score feasibility aspects of the content of 5 LKS developed very valid category is 4.21, the average score 4.34 categories designing aspect is very valid, and the mean score of the pedagogic aspect is 4.69 very valid category. The mean overall score of the fifth aspect is 4.41 LKS very valid category. I trial results showed the average score 4.21 with very good category. II trial results showed a mean score of 4.57 in very good categories. The results of the analysis of the answers to the second trial showed a mean value of 87 in good categories. LKS oriented discovery learning model can increase the understanding and knowledge about the digestion system and can increase critical thinking skill of student.

Abstract

Tujuan penelitian ini adalah untuk mengetahui perbedaan hasil belajar siswa pada materi Wujud Zat dan Perubahannya di kelas VII Mts Nahdhatul Atfhal Sungai Ambawang sebelum dan setelah di terapkan model pembelajaran Generatif dengan Kerangka Kerja TPCK. Metode yang digunakan yaitu Pre-Experimental Design dengan rancangan One Group pretest-posttest design. Instrumen dalam pengumpulan data adalah tes tertulis dalam bentuk Essay yang di ujikan kepada 27 orang siswa yang dipilih dengan teknik pengambilan sampel yang digunakan yaitu Cluster Random Sampling. Dari hasil penelitian diperoleh bahwa rata-rata hasil belajar siswa sebelum diterapkan model pembelajaran generatif dengan kerangka kerja TPCK sebesar 48,00 dengan standar deviasinya 13,29 dan rata-rata hasil belajar siswa setelah diterapkan diterapkan model pembelajaran Generatif dengan kerangka kerja TPCK 72,96 dengan standar deviasinya 10,40. Dari hasil analisis menggunakan Uji Wilcoxon diperoleh  yaitu 4,54 > 1,645. Simpulan dari penelitian ini adalah model pembelajaran Generatif dengan Kerangka Kerja TPCK dapat meningkatkan hasil belajar siswa.

Abstract

Background: Diarrhea is still a major health problem in Indonesia. This is due to the lack of knowledge about society hygiene and sanitation as well as there are still many people who haven't got health access. Guava (Psidium guajava) is a plant that has long been known by locals as traditional medicine. Some research has shown that extracts of the guava flesh is effective as an antidiarrheal. In addition, guava possessed efficacy as an anti-inflammatory, anti-mutagenic, anti-microbial and analgesic. Objective: To determine the effect of various concentrations of guava infusion leaves inhibiting E. coli growth in vitro. Methods: Third, fourth and fifth leaf from the tip were used as the materials. Leaves infusion concentration used was 20%, 40%, 60%, 80% and 100%. Each concentration infusion loaded into wells of Mueller-Hinton (MH) agar media. Radical zone around the wells measured as bacterial growth inhibition. The data were analyzed using one way analysis of variance (One-way ANOVAs). Results: There is the influence of infusion of guava leaves (Psidium guajava) on the growth of E. coli in vitro with a mean diameter of the smallest concentration of radicals zone which is 20% of 15.3 mm and the greatest concentration of 100% by 22 mm. Conclusion: Infusion of guava leaves have a strong influence in inhibiting E. coli growth as it has antibacterial chemical components.

Abstract

The increase in household electrical energy causes shrinkage of energy so that efforts are needed to conserve energy, especially electrical energy. One attempt to reducing the scarcity of electrical energy is by changing behavior. Changes in the behavior of electricity consumption can be influenced by psychological factors (norms, awareness, etc.), demographic factors (age, gender, income, etc.), and other factors such as regulations or policies from the government to conserve energy. This study seeks to determine the effect of psychological and regulatory factors on the behavior of household electricity consumption based on age. The method used was to conduct a survey by distributing questionnaires, the respondents obtained were 808 respondents. The results of the questionnaire were processed using the Structural Equation Model Partial Least Square (SEM-PLS) using the Smart-PLS software. The results of this study indicate that psychological and regulatory factors can explain their effect on the behavior of electrical energy consumption for ages <30 years of 50.9%. For 30-50 years old it is 49.5% while those> 50 years old are 59.3% and the rest is explained by other factors / variables outside those that have been studied so that it can be concluded that psychological factors and regulatory factors have a significant and significant influence. positive behavior towards household electrical energy consumption at all ages. it is expected that the results of this study can become the basis for making stronger regulations or policies in the field of energy conservation.
