Abstract: The research aimed to improve the achievement of learners on termochemistry subject in XI MIA class SMAN 1 Tanjungpinang. This research was a kind of experimental research with pretest-posttest design. The research was conducted in SMAN 1 Tanjungpinang the samples of the research were the students of XI MIA1 class as the experimental class and students of XI MIA2 class as the control class which were determined randomly after doing normality test and the homogeneity test. The learning process of experimental class and control class used scientific approach which was based on the curriculum in 2013. Experimental class was a class which was given the treatment that used cooperative learning model snowball throwing while the control class was not.

Abstract

Abstract : The research about use of media monopoly game has been applied to improve students learning result on the subject of hydrocarbon in class X SMAN 3 Pekanbaru. Form of research is experiment research with randomized control group pretest-posttest design. The population consisted of three classes, that is X1, X2, and X3. The sample used, that is X2 as experiment class and X1 as control class that randomly determined after testing normality and homogeneity. Experiment class was given treatment with using media monopoly game while the control class without use media monopoly game. Analysis of data used t-test. Results of the analysis it was found that tscore > ttable (3,06 > 1,67), it means that the use of media monopoly game can improve students learning result on the subject of hydrocarbon in class X SMAN 3 Pekanbaru. The category improvement of students learning achievement in experiment class was high category (N-gain =0,75) and in control class was medium category (N-gain =0,69).Key Words : Media Monopoly Game, Learning Result, Hydrocarbon

Abstract

Lactalbumin is a major protein found in milk which has great function to human body. It is a component of wheyprotein in milk. Lactalbumin was isolated from cow’s milk of Fries Holdstein breed by centrifugation at high speed9500 rpm and gel filtration chromatography using sephadex G-50 produced Lactalbumin dissolved in Tris buffersolvent. Characterization of Lactalbumin by measuring the UV absorbance spectrum at 240 – 320 nm comparedwith the spectrum of standard Lactalbumin showed maximum peak at the same wavelength, 280 nm. Lactalbumincontent in milk determined by Lowry method was about 0,66 mg/ml in milk or 9,2% of whey.

Abstract

This study aims to produce an assessment instrument to assess the ability to think creatively on hydrocarbon material and determine the validity of the assessment instrument. The research method used the research and development model of Borg and Gall. This research stage was carried out until the development stage. The assessment instrument developed in this study consisted of twenty-four items in the essay test, which referred to creative thinking indicators, which consisted of 4 indicators. Validation of the instrument for assessing the ability to think creatively was carried out by three validators with expert validity and validation of the measurement of creative thinking skills by experts measured using the Guttman scale. Based on the validity according to the expert, namely the material, construction and language aspects with the Aikens formula, it was obtained that the average expert validation ranged from 0.87 to 0.94 for the very good category, and 12 questions were declared valid. The validity of measuring the ability to think creatively using the Guttman scale obtained the results of 97.2% declared valid. 12 The developed test instrument is considered valid so that it can be used as a measuring tool to determine students' creative thinking abilities.

Abstract

Penelitian ini bertujuan untuk mengembangkan media komputer program eXe Learningdengan Strategi Pembelajaran Berbasis Masalah (SPBM), sebagai usaha untuk meningkatkan hasilbelajar dan hubungannya terhadap motivasi mahasiswa pada matakuliah Kimia Dasar I. Populasi dalampenelitian ini adalah seluruh mahasiswa tingkat pertama Jurusan PMIPA FKIP UR angkatan 2014 yangterdiri dari empat program studi, yaitu program studi pendidikan biologi, fisika, kimia dan matematika.Sampel penelitian diambil secara acak. Uji persyaratan analisis data digunakan uji kolmogorov-smirnovuntuk uji normalitas dan analisis varians untuk uji homogenitas. Pengujian hipotesis data motivasi belajardan hasil belajar menggunakan Independen sampel T-test SPSS-17. Hipotesis motivasi dan hasilbelajar diperoleh Sig. (2-tailed) < á =0,05 maka Ha1 dan Ha2 diterima, jadi terdapat perbedaan yangsignifikan motivasi dan hasil belajar mahasiswa yang diajarkan menggunakan strategi pembelajaranberbasis masalah dibandingkan dengan motivasi dan hasil belajar mahasiswa yang diajarkan menggunakanstrategi pembelajaran berbasis masalah yang diintegrasikan media komputer program eXe learning.Pengujian hipotesis hubungan motivasi dengan hasil belajar mahasiswa menggunakan CorrelationsSPSS 17. Pada kelas yang diajarkan dengan strategi pembelajaran berbasis masalah diperoleh Sig.(2-tailed) > á =0,05 yang artinya Ha3 ditolak, jadi tidak terdapat hubungan yang signifikan antaramotivasi dan hasil belajar. Sementara pada kelas yang diajarkan dengan strategi pembelajaran berbasismasalah yang diintegrasikan dengan media komputer program eXe learning diperoleh Sig. (2-tailed)< á =0,05 maka Ha4 diterima, jadi terdapat hubungan yang signifikan antara motivasi dan hasil belajar.Kata Kunci: Hasil belajar, motivasi belajar, media eXe Learning, strategi pembelajaran berbasismasalah
