This research aims at improving of physic teachers’ professionalism and students’ critical thinking through lesson study guidance. This research was action research through lesson study. The research subjects were teachers and students of the tenth graders of physic subject. The data collection was conducted in making requirement guidance and teaching learning process. After collecting data, the data analysis used was descriptive statistics. Based on the results of data analysis, there was improvement of physic teachers’ professionalism conducted each cycle and also students’ critical thinking was improvement each cycle. Even though, in the third cycle was decreasing, the fourth cycle was significantly improvement. It can be seen from the mean score of critical thinking indicators of each cycle: the first cycle was 26, the second cycle was 64, the third cycle was 54, and the fourth cycle was 74. Penelitian ini bertujuan meningkatkanprofesionalitas guru fisika dan keterampilanberpikir kritis siswa melalui pendampingan lesson study.Penelitian ini menggunakan penelitian tindakan dengan lesson study. Subyek penelitian ini adalah guru dan siswa kelas X mata pelajaran Fisika, Pengumpulan data dilakukan pada saat pendampingan pembuatan perangkat pembelajaran dan pada saat proses pembelajaran, setelah data terkumpul kemudian dianalisis menggunakan statistik deskriptif. Berdasarkan hasil analisis; terjadi peningkatan profesinalitas guru fisikapada setiap siklus pembelajaran yang dilakukan.Hal ini ditunjukan dengan semakin baiknya perangkat pembelajaran sebelum dilakukan diskusi plan, proses pembelajaran, dan evaluasi pembelajaran yang dilakukan. Demikian juga dengan keterampilanberpikir kritis siswa terjadi peningkatan pada masing-masing siklus pembelajaran,walaupun pada siklus ketiga terjadi penurunan tetapi dapat tertutupi oleh siklus keempat yang mengalami peningkatan cukup signifikan. Hal ini dapat dilihat dari rata-rata penguasaan indikator berpikir kritis siswa pada masing-masing siklus sebagai berikut, siklus pertama 26, siklus kedua 64, siklus ketiga 54, dan siklus keempat 74.

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.

This study aims to determine the increase in students' ability to analyze by applying modeling instruction and simulation media PhET. The research method used is a quasi experimental method with one group pretest posttest design. In this study, samples were taken as many as 33 people. The instrument used in the study was a multiple choice test. This test consists of 5 questions in the analyze category. Data analysis in this study used the Gain Normality Test. From the calculation results obtained an average value of N-gain of 0.7, it can be concluded that the application of modeling instruction and simulation media PhET can improve the ability to analyze students.
