Abstract

Tujuan penelitian ini untuk mengolah sampah plastik menjadi BBM dengan metode pirolisis sebagai energi alternatif dan mengolah kembali gas hasil pirolisis sebagai sumber energi. Metode penelitian yang digunakan adalah eksperimen. Data  hasil  penelitian dianalisis  dengan  cara  mengamati secara  langsung  hasil  eksperimen,  kemudian menyimpulkan   dan   menentukan   hasil   penelitian yang  telah dilakukan dengan menggunakan teknik analisis regresi berganda. Parameter yang diamati dalam penelitian ini adalah suhu reaktor, waktu pirolisis, dan densitas minyak plastik. Pirolisis sampah plastik ini menggunakan sampah jenis PolyPropylene dan sampah plastik jenis High Density PolyEthylene. Proses  pirolisis  dijalankan  dalam  reaktor yang berisi 0,5 kg plastik dengan variasi suhu 1000 C, 1500 C, 2000 C, 2500 C, dan 3000 C. Untuk menghemat bahan bakar dalam menamaskan reaktor maka digunakan gas sisa pirolisis yang tidak dapat terkondensasi pada tabung kondensor. Hasil penelitian menunjukkan minyak hasil pirolisis terbanyak dari sampah plastik PolyPropylene dan High Density PolyEthylene diperoleh pada suhu operasi 3000 C sebanyak 110 ml dan 145 ml. Waktu tercepat proses pirolisis plastik PolyPropylene adalah 60 menit  dengan nilai densitas minyak sebesar 818,181 kg/m3dan plastik High Density PolyEthylene adalah  30 menit dengan nilai densitas minyak sebesar 714,285 kg/m3 serta 551,728 kg/m3. Densitas  minyak  hasil  pirolisis  pada plastik PolyPropylene mendekati densitas bahan bakar etanol dan solar masing-masing 777,777 kg/m3 dan 818,181 kg/m3. Sedangkan pada plastik High Density PolyEthylene nilai densitas mendekati bahan bakar bensin sebesar 714,285 kg/m3. Data analisis regresi berganda pada plastik PolyPropylene dan High Density PolyEthylene menunjukkan bahwa suhu, waktu pirolisis dan densitas memiliki hubungan yang sangat kuat dan saling mempengaruhi satu sama lain.

Abstract

This study aims to determine the effect of the NHT and TPS learning models on student achievement, the effect of motivation on student achievement, and the interaction between learning models and motivation on student achievement. This type of research is experimental research. The population in this study were all students of class VII MTs. NW Wanasaba totaling 60 people consisting of 3 classes, namely: class VIIA, VIIB and VIIC. The research sample was class VIIA and VIIB which was obtained by means of Cluster Random Sampling. The data collection technique was carried out using multiple choice objective test method. The prerequisite test used is the normality test and homogeneous test, where the normality test uses the chi-square test and the homogeneity test uses the Bartlet test. While the data analysis technique used to test the hypothesis is the Two Way ANOVA test and the Scheff test for further ANOVA testing. The results of the analysis in this study indicate that there is an influence of the NHT and TPS learning models on student achievement, there is an influence of motivation on student achievement, and there is no interaction between learning models and motivation on student achievement.

Abstract

This research aimed at improving critical thinking ability of the fourth  semester students in mechanics course of physics education at  Universitas Hamzanwadi. Method applied was  problem based learning through lesson study activity which covered open class four cycle. Media used was cut of papers contained  formula or mathematics equation which were called Cards of the formula, the cards were given in every open class activity. The data of critical thinking ability taken from critical thinking test administered by the end o, pices of f lecturing activity. Qualitative data taken from obseravtion result during the lecturing. From the activity, it was found that students’ critical ability in every element namely giving argument ability , formulating problem,  doing induction, and by doing deduction, average scores above 3 was got which were categorized into high and medium.

Abstract

This research aims to develop E-LKPD based on local wisdom of Loyok bamboo woven crafts with a project-based learning model on Newton's Law material for class X SMA/MA Science. This type of research is research and development with a 4D model (define, design, development, disseminate). Product testing is carried out through validation by material experts, media experts and physics subject teachers as well as student responses in the form of practicality tests. The data collection instrument uses expert validation questionnaires and student responses. The data analysis technique uses validator and student data tabulation, then calculates the average score, and calculates the score percentage. Based on validation from 3 material experts, it shows a percentage of 86% with a very feasible category, the assessment of 3 media experts shows that the quality of E-LKPD is included in the very feasible category with a percentage of 81%, and the results of the assessment of 2 physics subject teachers show that the quality is E -LKPD is included in the very feasible category with a percentage of 84%. Meanwhile, the response results from 11 students showed that 90.9% of respondents stated that the criteria were very practical and 9.1% of respondents stated that they were practical.
