Abstract: The research on application of active learning strategy planted questions to improve learning achievement of learners on the subject of solubility and solubility results in class XI MIPA SMAN 1 Kampar on April. Form of research is experimental research with pretest-posttest design. The sample consist of two class, namely class XI MIPA 1 as the experimental class and class XI MIPA 3 as control class which randomly selected after had tested normality and homogeneity. Experimental class is a class that implemented of active learning strategy planted questions while the control class used discussion information methods. Data analysis technique used is the t-test. Based on the results of the final data processing using t-test formula obtained tcount > ttable (4,615 > 1,669) means the application of active learning strategy planted questions can improve student achievement on the subject of solubility and solubility results in class XI MIPA SMAN 1 Kampar, with an increasing percentage of 23,851% .Keywords : Active learning strategy planted questions, Learning Achievement and solubility and solubility.

Abstract: This research aimed to increase student achievement by application ofcooperative learning model POE (Predict, Observe, Explain) on learning topic ofthermochemical in XI IPA SMA N 9 Pekanbaru. This is an experimental research withrandomized control group pretest-posttest design. Subject of this research are XI IPA 4as the experimental class, XI IPA 3 as the control class which were determinedrandomly after conducting normality and homogeneity test. The experimental groupwas treated with the application of cooperative learning model POE (Predict, Observe,Explain) while the control group without the application cooperative learning modelPOE (Predict, Observe, Explain). The data analysis to test the hypothesis was using ttestright side. Based on the data analysis, it is obtaine tcount = 3,53 and ttable = 2,00 withα=0,05, dk = 73, tcount > ttable is 3,53 > 2,00, It’s mean that the application ofcooperative learning model POE (Predict, Observe, Explain) can improve studentsachievement on the subject of thermochemical in XI IPA SMA Negeri 9 Pekanbaru.

Abstract: This study aims to determine the difficulties and factors that cause learning difficulties of students on the ion balance and pH of salt solution in class XI MIPA 3 SMAN 1 Kuantan Mudik. This research is a descriptive study with a qualitative case study approach, the population of class XI with a sample size of 35 people in class XI MIPA 3. The data collection technique uses the technique of test questions and questionnaires, and interviews, while the data collection tools use test questions and questionnaire sheets. The results showed that the students had difficulty learning in determining the pH of the salt solution with high and very high categories of learning difficulties. Internal factors that affect students 'learning difficulties are motivational aspects with indicators of learning efforts about ionic balance and pH of salt solution and students' attention to learning these materials with percentage effects of 59.28% and 57.85%, respectively, while external factors which affects learning difficulties in the aspects of teacher teaching 59.86% respectively. The conclusion of this study is that there are learning difficulties of students on the matter of ionic equilibrium and the pH of the salt solution and there are both internal and external factors that affect the learning abilities of students.Key Words: Analysis, Ionic Equilibrium and pH of Saline Solution, Learning Difficulties for

Abstract

Proses asimilasi dan adaptasi pada pengendalian dari persebaran COVID-19 berdampak pada fenomena tingginya stres kerja guru kimia di Provinsi Riau dalam menghadapi proses pembelajaran daring. Penelitian ini bertujuan untuk menganalisis pengaruh efikasi Diri dan penguasaan konsep kimia terhadap stres kerja guru kimia pada masa pandemi COVID-19 di Provinsi Riau. Metode Penelitian ini adalah kuantitaif dengan teknik korelasional pada pengaruh langsung. Populasi dalam penelitian ini adalah semua guru Kimia SMA di Provinsi Riau khususnya pada empat kabupaten/Kota yaitu Pekanbaru, Siak, Indragiri Hilir, dan Indragiri Hulu dengan jumlah populasi sebanyak 224 orang guru kimia, sedangkan sampel dalam penelitian diambil dengan teknik proportionate random sampling sehingga diperoleh 144 guru kimia. Pengumpulan data dilakukan dengan kuesioner online dengan menggunakan skala efikasi diri, penguasaan konsep kimia dan stres kerja guru kimia. Kuesioner telah dinyatakan valid dan reliabel dalam uji coba terhadap 23 orang sampel guru kimia. Teknik analisis data dilakukan dengan analisis regresi linier berganda. Hasil penelitian menunjukkan bahwa efikasi diri, dan penguasaan konsep berpengaruh negatif signifikan terhadap stres kerja guru kimia pada masa pandemi COVID-19. Penelitian ini memberikan rekomendasi bahwa guru kimia dalam meningkatkan indikator keyakinan dalam mengajar (efikasi diri), kemahiran (penguasaan konsep kimia). Selain itu, penelitian ini juga memberikan saran agar guru memiliki strategi koping dalam menghadapi stres terutama yang bersumber dari sistem sekolah, tuntutan pengembangan diri dan fasilitas perangkat keras sekolah
