Get PDFAbstract
The purpose of this research is to calculate the binding energy and disintegration energy with the binding energy liquid drop model approach. This research is modeling research. The steps: 1) prepare supporting materials for research on stability and elements in the radioactive process; 2) reviewing materials that have been obtained previously; 3) do calculation simulation; 4) analyze and discuss the results of calculations; 5) conclude the results of the study. The calculation results show that the element has the largest binding energy of 1805,1 MeV and has the smallest binding energy per nucleon that is equal to 7,584 MeV, while the resulting child nuclide has the smallest binding energy of 1612,2747 MeV and has the largest binding energy per nucleon of 7,8266 MeV, so that the binding energy has a decreased graph while the binding energy per nucleon has a rising graph. The biggest disintegration energy in the uranium series decay process occurs at decay of alpha to be which is equal to 5,1037 MeV while the smallest disintegration energy occurs at beta decay becomes which is equal to -0,2639 MeV.

ANALISIS KEMAMPUAN BERPIKIR KRITIS SISWA PADA PEMBELAJARAN KIMIA: Materi Reaksi Redoks dan Elektrokimia MENGGUNAKAN MODEL PROBLEM BASED LEARNING
Get PDFAbstract: This study aimed to analyze the learning activities of students inthe chemistry learning process by using the problem base learning (PBL)learning model. This research was an experimental study using ControlGroup Design on 12th grade science students at High School TegaldlimoBanyuwangi, East Java. As a control class was class 12 IPA-1 and as anexperimental class was class 12 IPA-2. Learning chemistry of redox andelectrochemical reaction materials in the experimental class used theproblem base learning model, while learning in the control class did not usethe problem base learning model. Aspects of critical thinking skills reviewedinclude 3 aspects: (1) Elementary clarification (giving basic explanations),which was about what known and what the core problem; (2) The basis forthe decision (determining the basis for decision making), namely the rightreasons as the basis before a step was taken; (3) Inference (drawingconclusions), namely drawing correct conclusions must be based on reasonsthat are reasonable or logical. Student learning activities during the studywere also observed to include: 1) involvement in discussion, 2) involvementin carrying out practicum, 3) discipline in learning, 4) responsibility. Theresults of the analysis using the t-Test statistical analysis with a 95%confidence level proved that the students' ability to provide explanations,decision making, and the ability to draw conclusions in the experimentalclass students were significantly higher than those in the control class.Keywords: Problem Based Learning Model, Critical Thinking Abilit

Get PDFAbstract
This research is development research. This study aims to examine expert validation, describe student learning outcomes, and describe the effectiveness of Contextual LKS Based Process Oriented Guided Inquiry Learning (POGIL) Class X Motion Material. The research subjects were 39 students of SMAN 1 Gambiran class X. Data on expert validation was obtained from five the validator is two lecturers of the University of Jember Physics Education Program, and three high school Physics study teachers in the development test. Data on learning outcomes are obtained from the results of post tests conducted after the learning is complete. The results showed that quantitative data validation logic from five validators for Contextual LKS Based on Process Oriented Guided Inquiry (POGIL) of 3.53 with a fairly valid category. This assessment is the average of the assessment of conformity components of 3.5; the effectiveness component is 3.875, and the feasibility component is 3.22. Cognitive domain assessment gets the lowest score among the other domains at 63. Classically the average student learning outcomes are 73.61 and are categorized as being moderate. The conclusions obtained from this study are 1) Validation results from 5 validators consisting of two physics education lecturers and 3 Public High School 1 Gambiran teachers Contextual LKS Based on Process Oriented Guided Inquiry Learning (POGIL) categorized as quite valid, 2) Student learning outcomes after using Contextual LKS Based on Process Oriented Guided Inquiry Learning (POGIL) in physics learning as a whole is 73.61 and categorized as moderate, and 3) Effectiveness based on learning outcomes can be seen in high criteria. These results can be used as a reference for validation of good literary audiences so that the Contextual LKS Based on Process Oriented Guided Inquiry (POGIL) can be said to be effective. This study can be used to identify factors that influence the level of mastery of concepts and student learning attitudes so that teachers can determine worksheets that suit the needs of students.
