<![CDATA[Science skills are skills that students need when they are investigating. These skills are needed by students in the process of inquiry to solve problems from a natural phenomenon that is around them. general reality many of the skills of students who tend to be passive and low. The low scientific skills of students because the learning process does not involve practicum. Therefore, this study aims to find out. Improved science skills in terms of high school student activities through inquiry training learning models. This type of research is descriptive. The instrument of this study was the activity evaluation observation sheet. Each student observation sheet consists of five indicators. The indicator is confronting the problem, verifying data, experimenting, processing data and inquiry analysis. The results showed that skills based on assessment of activity indicators increased at each meeting.]]>

<![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[Designing relevant, effective, and valid student worksheet teaching materials is the goal of this project. by utilizing a STEM strategy focused on e-learning for magnitude and units. The ADDIE model and the R&D approach were used to conduct this study. Three validators are used to determine the product's validity during the creation stage: material experts, media experts, and teachers. A normalized gain test (N-Gain) was conducted to evaluate the product's efficacy. Moreover, depending on the feedback from the students, to assess the product's practically. There are small-scale tests with 10 students and large-scale tests with 20 students used in product development. The instruments employed were expert validity questionnaires and student response questionnaires. Testing for validity, efficacy, and practicality on goods reveals that the produced LKPD is highly valid, highly effective, and highly practical as a teaching resource in learning activities.]]>
