<![CDATA[This research aims to determine the application of problem based learning (PBL) learning models on acid-base material for class XI science at SMA Negeri 1 Tenga. This research was conducted in class XI SMA Negeri 1 Tenga with a sample of 25 people. The research design used was the post-test-only control group design experimental method. The experimental class uses a problem based learning (PBL) model and the control class uses conventional learning. Analysis of hypothesis testing using t-test with a significant level of = 0.05 and success (dk) = 48. The test results obtained show that the results of tcount > ttable or 3.62 > 2.010, thus H0 is rejected and Ha is accepted, and the average the average student learning outcomes of the experimental class were 81.92, which was greater than the learning outcomes of the control class was 72.96. This shows that there is a significant difference between the average score (post-test) of the experimental group and the control group. So it can be concluded that there is a difference in the average learning outcomes of students who use the problem based learning (PBL) learning model with the learning outcomes of students who use conventional learning on acid-base materials.]]>

<![CDATA[Blended learning is mixed learning, namely online and face-to-face learning. Because it is still during the Covid-19 pandemic, learning is currently still being carried out online. To support the online learning process, the Zoom Cloud Meeting application is used. The learning process can also be carried out offline but in accordance with the protocol from the government. This study aims to determine student learning outcomes after being given treatment can exceed the KKM value. The study used an experiment with a one shoot case study research design. This research was conducted at SMA Negeri 1 Tutuyan for the academic year 2020/2021 with 29 students in class X MIA 1. The data collection technique was a posttest and the instrument used to measure learning outcomes was a multiple choice test. The results of this study used the t-test one sample t-test with the results of ttable 1.701 and tcount 28.8476 with a significant level of 5% and therefore ttable was smaller than tcount. Thus, it means that H1 is accepted and H0 is rejected. So it was concluded that student learning outcomes after being given treatment can increase and exceed the KKM value.]]>

<![CDATA[This research is an experimental research with Mastery Learning model. This study aims to determine the effect of the Mastery Learning model on student learning outcomes on the mole concept material. This research was conducted in class X SMA Negeri 1 Remboken with a sample of 57 people. The research design used is the post-test-only control group design experimental method. The experimental class uses a complete learning model and the control class uses a conventional learning model. Analysis of hypothesis testing using t-test with a significant level = 0.05, because with a two-way test then the value of a/2 = 0.025. The test results obtained show that the results of t arithmetic > t table or 9.02 > 2.05, thus H0 is rejected and H1 is accepted, this indicates that there is a significant difference between the average value (post-test) of the experimental group and the experimental group. control group experiment. So it can be concluded that there is a difference in the average learning outcomes of students who are taught the mastery learning model with the learning outcomes of students who are taught conventional learning on the mole concept material.]]>

<![CDATA[The demonstration method is a method that can make students' attention more focused on what is being taught so that students are more active and do not feel bored in learning. This study aims to see the effect of the demonstration method on student chemistry learning outcomes on colloidal system material at SMA Negeri 1 Tutuyan in the 2020/2021 academic year. This research is a pre-experimental research with one group pretest-posttest design. The population in the study were all students of class XI IPA and the sample taken was class XI IPA MIA 1, totaling 30 people. Testing the hypothesis using the t-test formula at the significant level = 0.05. Based on the data analysis, the value of tcount = 23.90 and ttable = 2.045. The value of tcount > ttable then H1 is accepted and H0 is rejected, so it can be concluded that H1 is accepted, which means there is a significant difference between student learning outcomes on colloidal system material before and after using the demonstration method because there are differences. student learning outcomes. To find out how much the effectiveness of using the demonstration method is continued with the N-Gain test and obtained is 0.76 with high criteria.]]>
