The research has been conducted to figure out the use of virtual laboratories on students' conceptual understanding of acid-base titration subject at SMAN 1 Tambusai. The study was an experimental research with one group pretest-posttest design. The sample consisted of one class, XI IPA2, a class that was treated with a virtual laboratory. The data analysis technique used was the t-test. Based on the results of the final data processing using the t-test, it was obtained that sig 5 ≤ 0.05; where 0,000 ≤ 0.05; so it was concluded that there were significant differences between the mean scores of the pretest and posttest. This shows that there is an increase by the use of virtual laboratories towards the students' conceptual understanding

Through this research, it is hoped that acid-base titration learning will be more meaningful and can contribute to student creativity. PjBL model is an integrated learning that is carried out cooperatively through projects that develop student skills, so that student creativity will increase. The project given in this research is making of soap from the wrinkled oil. In the process can be attributed to the application of acid-base titration material by calculation of acid numbers and saponification numbers on the cooking oil before being processed into soap. The results of data analysis shows data significance> 0.05 which means that the data is normally distributed for pretest and posttest. The data of paired sample t-test shows that the significance obtained is 0,000 <0.05 which means that there is a significant difference between the mean value of the integrated creativity test with the acid-base titration concept before treatment is given after treatment is given. Creativity improvement were calculated using the N-Gain value resulting in an average achievement rate of 0.50 and belonging to the moderate category. Posttest results indicate that the implementation of project-based LKP is effective in improving student creativity with classically average is 81.5%.

The research was an experimental study to identify differences on process skills and student’s achievement by using real and virtual laboratories in acid base titration. The subject was students of 11st science class at Wachid Hasyim 2 Taman Sidoarjo High School. The research used 4 classes with real laboratory learning class as a control class while 3 classes given by the virtual laboratory as an experimental classes. Design of research was Control Group pre-test-post-test design. The result was a feasibility lesson plans on using real laboratory showed similar results with learning using virtual laboratory were categorized very wel l, student activity during the learning process using real and virtual  laboratory showed the same result were an increase in inquiry activities. The average value of the process skills of students used real laboratory on control class is 79,12 and virtual laboratory on experiment class 1, 2, and 3 were 80,18; 79,88; and 81,16 respectively.  The average value the results of student’s  achievement  used real laboratory on control class is 78,25 and virtual laboratory on experiment class 1, 2, and 3 were 79,48; 79,63; and 80,26 respectively. Process skills showed correlation with student’s achievement in use real and virtual laboratories. The conclusion was there are no differences in the skills process and student’s achievement by using real and virtual laboratories in acid base titration therefore virtual laboratory could be used as simulation media in schools with computing facilities before students learn using real laboratory. The virtual laboratory were not a competitor and didn’t function to replace the real laboratory.Penelitian ini merupakan penelitian eksperimental yang bertujuan untuk mengetahui perbedaan keterampilan proses dan hasil belajar siswa dengan menggunakan laboratorium real dan laboratorium virtual materi titrasi asam basa. Subyek penelitian adalah siswa kelas XI IPA di SMA Wachid Hasyim 2 Taman Sidoarjo. Uji coba penelitian menggunakan 4 kelas dengan pembagian 1 kelas diberikan pembelajaran dengan laboratorium real sebagai kelas kontrol sedangkan 3 kelas diberikan pembelajaran dengan laboratorium virtual sebagai kelas eksperimen. Penelitian ini menggunakan rancangan penelitian Control Group pre-test-post-test Design. Hasil dari penelitian ini adalah keterlaksanaan RPP pada pembelajaran menggunakan laboratorium real menunjukkan hasil yang sama dengan pembelajaran menggunakan laboratorium virtual yaitu berkategori sangat baik, aktivitas siswa selama pros es pembelajaran menggunakan laboratorium real dan laboratorium virtual menunjukkan hasil yang sama yaitu mengalami peningkatan dalam kegiatan inkuiri. Nilai rata-rata keterampilan proses siswa yang menggunakan laboratorium real pada kelas kontrol sebesar 79,12 dan menggunakan laboratorium virtual pada kelas eksperimen 1, 2, dan 3 berturut-turut sebesar 80,18; 79,88; dan 81,16. Nilai rata-rata hasil belajar siswa yang menggunakan laboratorium real pada kontrol sebesar 78,25 dan menggunakan laboratorium virtual pada kelas eksperimen 1, 2, dan 3 berturut-turut sebesar 79,48; 79,63; dan 80,26. Keterampilan proses menunjukkan adanya korelasi dengan hasil belajar produk pada pembelajaran yang menggunakan laboratorium real dan laboratorium virtual. Simpulan dari penelitian ini adalah tidak ada perbedaan pada keterampilan proses dan hasil belajar siswa dengan menggunakan laboratorium real dan laboratorium virtual materi titrasi asam basa sehingga laboratorium virtual dapat digunakan sebagai media simulasi pada sekolah yang memiliki fasilitas komputasi sebelum siswa belajar menggunakan laboratorium real.

This study aims to determine the effectiveness of CSM strategies on comprehension reading skills in classes V Padokan 2 Elementary School. The research method used is a quasi-experimental method. In this study the subjects of the study were VA class students as the control class and V C as the experimental class with 28 VA and VC class students. Quantitative data analysis technique used is the calculation of independent sample t-test. Based on data analysis and discussion, researchers can conclude that CSM strategies are more effective than conventional methods of reading comprehension learning. The results of this study indicate that there is a significant difference between the experimental class and the control class as evidenced by the results of the independent sample t-test obtained by the value of Asymp. Sig (2-Tailed) 0.014 <0.05. CSM strategy is an effective learning strategy seen from the average value of the experimental class posstest which is 81.61 higher than the control class average value of 72.96.

Visionary leadership is a capability to make changes by having new visions and ideas, thinking ahead, carrying out stages of mutual interconnection that can influence and motivate teachers and their students. This research aims to find out the effect of leadership of Madrasah Principal Visionary to Teacher Discipline. The type of this research is quantitative research. The population in this study were all 60 teachers in MAN 2 Samarinda. The data of this research is obtained from questionnaire, observation and documentation. The data analysis technique uses product moment correlation formula, determinant coefficient (R²) and t test. The results of this study shows the results of the t-test value of 3.5090> t table 2.00172, which means that Ho is rejected and Ha is accepted. The meaning is there is a correlation between variable X and Y, product correlation 0.416. That means there is a strong correlation between visionary leadership variable and teacher discipline variable. Percentage of visionary leadership for teacher  discipline is 17.30% (strong enough), the factors that cause these results include: giving the best performance without analyzing / following new era, inability to change teachers knowledge into strategy, and treating teachers differently causing conflicting duties. The supporting and inhibiting factors in managing teacher discipline include: teacher personalitty, the headmaster teachers supervision.
