<![CDATA[This study aims to determine the effect of the composition comparison of the PVA-Enzyme urease coating PVC-Plastisizer KTpClPB membrane with memmbran characterization using FTIR and analyze membrane electrodes with XRD. The method used is the potentiometric method using the Electrode Selective Ion (ISE), where the polymer used is PVA and PVC as a coating with a composition ratio of PVA: PVC is 1: 1. The same PVA and PVC were used, namely 0.0350 g, with 2 mg of enzyme and 0.0500 g and 0.0120 g of KTpClPB plasticizer. The best composition result is the PVA-Enzyme PVC-Plastisizer coating enzyme KTpClPB 0.0500 g membrane electrode characterization using XRD shows the highest intensity value is at an angle of 2θ = 44.020 which is 1,626 count second (cts) and membrane characterization using FTIR shows that there is a functional group OH, CH, C≡C, NH, CO and CH. The addition of PVA-Enzyme coating will reduce or even eliminate the amount of Wolframm and can reduce the amorphous properties of the membrane electrodes.]]>

<![CDATA[Practical methods are very rarely used in learning physics so that Students have difficulty understanding concepts. Student Worksheets are needed to support practical work. Student Worksheets used in learning are not feasible. Fulfillment of the feasibility test in learning in this study is intended to test and determine the level of feasibility of Student Worksheets Based on the Starter Experiment Approach (SWBSEA). The design of the SWBSEA is based on curriculum needs, Student knowledge, and Student skills. Testing the level of feasibility and application of SWBSEA is given to Students during learning and submits a questionnaire to assess the feasibility of use. The results showed that SWBSEA in Physics learning was considered feasible in terms of Content Display, Subject Display, Component Completeness, and Grammar.]]>

This research is an exploratory type of research that aims to find out the difficulties experienced by students in mathematics physics lectures and solutions to overcome them. The method used is quantitative and qualitative research methods with data collection instruments in the form of questionnaires and interview sheets. The number of samples set by the researchers amounted to 30 students as the subject of distributing the questionnaire and 10 students as the subject of the interview. The sample in this study was selected by purposive sampling technique. The data analysis carried out by the researcher was using statistics while the data analysis from the interviews was carried out with 3 main activities, namely data reduction, data presentation, and drawing conclusions. The result of this research is that students have difficulty understanding the material in my mathematics lectures because of the use of books that are less varied and the main books used in English and the derivation of formulas are not presented in detail. Therefore, researchers are encouraged to develop electronic modules where 43.3% of students agree and 23.3% of students strongly agree to develop electronic modules in mathematics practicum I lectures.Keywords: development; electronics module; mathematical physics I]]>

<![CDATA[Learning motivation is crucial in the learning process. The motivation to learn will also be able to affect their academic abilities, and this will be one of the supporters of the success of the learning process. Judging from the importance of the function of learning motivation, the purpose of this study is to measure the level of learning motivation through self-assessment instruments with the aim of knowing how high learning motivation is in learning physics. The object of this research was the students of class X SMA 1 Kalasan, with a total of 60 respondents. This research is development research with a 4D design, namely define (definition), design (planning), develop (development, and disseminate). The data collection method in this study uses a questionnaire method with a Likert scale. Based on the results of the analysis, the self-assessment instrument has validity and is quite good with numbers above 0.330. And the reliability is quite high with the number 0.492. Based on this data, the self-assessment instrument can be said to be valid and reliable, so it is feasible to use it to measure the learning motivation of students.Keywords: Instruments; Self-assessment; Learning motivation ]]>

<![CDATA[This study aims to determine the effect of the discovery learning model on learning outcomes in the material Temperature and Heat in class XI SMAN 1 Sibolangit T.P 2022/2023. The type of research used is a quasi experiment. The population in this study were all students of class XI SMA N 1 Sibolangit. Sampling was done by cluster random sampling by taking 2 classes out of 6 classes randomly, namely XI MIA 3 as the control class, totaling 30 people and XI MIA 2 as the experimental class, totaling 32 people. The instrument used to determine student learning outcomes is a student learning outcomes test. In testing the normality of the pretest values in the experimental class, it was obtained Lcount < Ltable, so the data for both classes were normally distributed. In the homogeneity test obtained Fcount <Ftable, then both samples come from homogeneous groups. Then given a different treatment, the experimental class with the discovery learning model and the control class with conventional learning. After learning was given, the average value of the posttest experimental class was higher than the average value of the control class. The results of the t test obtained tcount > ttable, so ha was accepted. Thus, it was found that there was an influence of the discovery learning model on student learning outcomes in the subject of temperature and heat in class XI SMAN 1 Sibolangit T.P 2022/2023.]]>
