Kemampuan Pemecahan Masalah Pembuktian Siswa SMP Berbantuan Geogebra
Get PDFProof problem solving ability is an important part of the independent curriculum. However in reality, this ability is difficult for students to master because students are still unable to connect known facts with the elements to be proven so the need for the use of tools to improve students' problem solving skills. Geogebra can also facilitate students in every stage of solving proof problems. This research is a qualitative descriptive research that aims to describe the problem solving ability of Geogebra-assisted junior high school students. The subjects of this study were 4 students including 2 students with high ability and 2 students with moderate ability. The results showed that at the stage of understanding the problem, students with high and medium mathematical abilities could identify the information given. Although at first students with moderate ability experienced misunderstandings, these students could realize the misunderstanding with the help of Geogebra. Geogebra is very useful in helping students to understand the meaning of the problem and makes it easy to make visualizations quickly and accurately. At the stage of developing a solution plan, students can make several plans. With the help of Geogebra, students with moderate ability can determine the solution steps that are more precise and easy to understand. In addition, with Geogebra students can help to bring up concept ideas in problem solving. At the stage of implementing the plan, students with moderate ability have difficulty in implementing the plan, but with the help of Geogebra, students with moderate ability can re-examine the visualization results to get a new plan. Students use Geogebra to explore the plans that have been made to find the solution steps. At the stage of re-examining the solution, only students with high ability see the correctness of the results for all situations
Penerapan Model Pembelajaran Discovery Learning Berbantuan GeoGebra untuk Meningkatkan Hasil Belajar Materi Fungsi Kuadrat
Get PDFQuadratic function is important for students to understand because they are useful for everyday life. In reality, most students still face difficulties in solving quadratic function problems. Meanwhile, quadratic function material is needed to understand subsequent material topics such as integrals, derivatives and linear programming. Apart from that, the results of observations on quadratic function material, students do not understand the visualization of quadratic function graphs and students tend to memorize formulas so that when faced with a problem, students forget which formula to use. The application of discovery learning combined with the use of GeoGebra has the potential to stimulate student understanding so that it has a positive effect on learning outcomes. Therefore, the aim of this research is to implementation discovery learning model assisted by GeoGebra to find out actions that can improve learning outcomes. This research uses Classroom Action Research (PTK) guided by the Mc. Taggart and Kemmis design with research stages which include planning, action, observation, and reflection. The subjects in this research consisted of 35 students from class X-K MAN 1 Trenggalek. Data is obtained by observing and administering tests at the end of each cycle. The research results reported that the average value of student learning outcomes after participating in Cycle I learning activities was 67.13 and 74.64 after participating in Cycle II learning activities. Apart from that, the results obtained in Cycle I of student learning completion were 65.71% and in Cycle II it was 77.14%. Student learning outcomes on the topic of quadratic functions can be improved through learning that applies discovery learning assisted by GeoGebra

Sentiment Analysis of 2024 Election Fraud Using SVM and Naïve Bayes Algorithms
Get PDFElections are one of the main pillars of democracy, where the people's voice is the main determinant in government formation. Election fraud not only harms political competitors but also undermines public trust in democracy. The role of social media Twitter in widely disseminating information and disinformation adds to the challenge of maintaining election integrity. Sentiment analysis is the process of collecting and understanding individual opinions related to an event. Support Vector Machine (SVM) and Naïve Bayes algorithms are often used in this analysis due to their effectiveness and efficiency in text classification. This research aims to analyze public sentiment related to the 2024 presidential election fraud and compare the effectiveness of SVM and Naïve Bayes in sentiment classification. The study was conducted quantitatively, involving the stages of data collection, preprocessing, labeling, TF-IDF weighting, classification, and evaluation. The results of the sentiment analysis of public opinion on the 2024 presidential election fraud showed 42.5% negative sentiment, 38.6% neutral, and 18.9% positive. The dominance of negative sentiments reflects the public's concerns about election integrity. The high neutral sentiment indicates public doubt. To overcome this, transparency, strengthening supervisory institutions, electronic election technology, and strict law enforcement are needed. The SVM algorithm with RBF kernel produces 58% accuracy, better than Naïve Bayes with 51%
Analysis of Factors Influencing Acceptance of the Online Population Administration Information System in Mojokerto Regency Using Technology Acceptance Model (TAM 3)
No full textThis research investigates factors influencing the acceptance of the POSKeTanMu online population administration system in Mojokerto Regency using the Technology Acceptance Model (TAM 3). POSKeTanMu (Pelayanan Online Sistem Kependudukan Tanpa Ketemu) is a self-service online population administration system for residents of Mojokerto Regency. A quantitative approach with Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied, analyzing data from 159 respondents through questionnaires. Findings indicate that Behavioral Intention (BI) significantly influences user independence and responsibility. Key factors affecting technology acceptance include perceived usefulness, ease of use, social influence, and experience, while computer anxiety and system usability showed no significant impact. Additionally, the study explores the implementation of the Double Track program using a qualitative case study approach, guided by Thomas Lickona’s character-building theory. Data collection involved interviews, observations, and documentation, analyzed using Miles and Huberman’s framework. Results highlight ease of use, perceived benefits, and social perceptions as major drivers of technology adoption. Positive user experiences and social support play crucial roles in enhancing e-government adoption. This research contributes to the development of POSKeTanMu and provides strategic recommendations for the government to strengthen digital service implementation. Findings offer valuable insights for policy formulation to improve e-government services and promote broader technology adoption in society
