Pengaruh Media Sedotan Plastik Terhadap Keterampilan Guling Depan Siswa Kelas V MI Islamiyah Tulungagung
No full textThe main difficulty in learning forward rolls in elementary school gymnastics often lies in incorrect head and neck positioning, which prevents rotation and increases the risk of injury. This study aims to examine the effect of using plastic straws as a learning aid to improve students' forward roll skills. The method used is a quasi-experiment (pre-experiment) with a one-group pretest-posttest design. The research subjects were 30 fifth-grade students at MI Islamiyah Tulungagung who were given treatment during six meetings with the help of plastic straws placed between the chin and chest as an indicator of head position. Skill data were assessed through an observation test covering initial attitude, process, and final attitude aspects, then analyzed using a paired sample t-test and Cohen's d effect size calculation. The results showed an average skill improvement from 60.13 (pretest) to 70.83 (posttest), with a significant difference (p = 0.001). The effect size was categorized as moderate (d = 0.65). Based on these findings, it can be concluded that plastic straws are effective and have a significant influence in improving students' forward roll skills, particularly through improving head position during rotation. This medium is recommended as a simple, inexpensive, and direct feedback-based learning alternative for physical education teachers in elementary schools.Tujuan dari penelitian ini adalah untuk mengidentifikasi dampak dari pemakaian media sedotan plastik terhadap keterampilan guling depan siswa kelas V MI Islamiyah Tulungagung.

Model Hibrida K-Nearest Neighbors Berbasis Genethic Algorithm untuk Prediksi Penyakit Ginjal Kronis
Get PDFChronic Kidney Disease, which is often abbreviated as PGK, is a serious disease that is of major concern to society and the medical world. This disease can cause various serious complications if not treated properly and early. Therefore, accurate prediction of CKD is very important to support early intervention that can slow disease progression, prevent further complications, and increase the patient's chances of recovery. This research aims to increase the accuracy of PGK predictions by developing a hybrid model that combines the K-Nearest Neighbors (KNN) algorithm with optimization using the Genetic Algorithm (GA). In this approach, the KNN algorithm is used to build a prediction model, while GA acts as an optimization tool that improves model performance. The effectiveness of the optimized model is evaluated using key metrics such as accuracy, precision, recall, and area under the curve (AUC). The results show a significant increase in performance, with accuracy increasing by 17.75%, precision increasing by 23.84%, and recall increasing by 5.34%. This research makes an important contribution to the development of data mining technology for clinical applications and opens up opportunities for further improvements in the future in increasing the prediction accuracy of chronic diseases such as CK
Prediksi Diabetes Menggunakan Algoritma K-Nearest (KNN) Teknik SMOTE-ENN
Get PDFNowadays, diabetes is a common disease affecting millions of people worldwide, and it is generally more prevalent among women. Recent health research has adopted various innovative and advanced technologies to diagnose individuals and predict diseases based on clinical data. One such technology is Machine Learning (ML), which enables more accurate diagnosis and prediction. The data used in this study is the Pima Indian women diabetes dataset from Kaggle and the UCI data repository. This study focuses on predicting diabetes using the KNN algorithm model by applying optimization to the dataset using the SMOTE-ENN technique to enhance prediction accuracy for Pima Indian women. The dataset was trained and tested with five different splits using Jupyter Notebook to determine the best accuracy for the KNN algorithm model. Parameters such as classification accuracy, classification error, and the ROC curve were evaluated, along with identifying the variables influencing the risk of diabetes. The results showed that applying SMOTE-ENN optimization to the research dataset significantly improved the prediction accuracy using the KNN algorithm model. With a 70% training and 30% testing data split, the model achieved a classification accuracy of 0.96, a classification error of 0.04, and an AUC of 0.95. These predictions indicated that Pima Indian women are more likely to develop diabetes due to factors such as age above 33 years, the number of pregnancies, excessive sugar consumption, blood pressure, skin thickness, insulin levels, BMI (Body Mass Index), and genetic predisposition to diabete
Abstraction level of van Hiele’s theory: Occurrence of side effects in GeoGebra integration
Get PDFOne of the obstacles to teaching geometric transformation is the complex procedures that require a broad base of prerequisite knowledge. This complexity often leads students to focus on rote memorization and procedural calculations instead of understanding the underlying context. This study aims to overcome these challenges by developing a hypothetical learning trajectory (HLT) and using GeoGebra to enhance visualization and understanding. The case study involved ten university students in Indonesia who tackled the abstraction level in the Transformation, Isometries, and Reflection topics. The researchers analyzed students' worksheets, activity observations, and learning obstacle tests to extract their geometric thinking. Qualitative analysis of the data revealed that seven out of ten participants met three of the four abstraction level indicators. The use of GeoGebra in HLT helped overcome epistemological obstacles. However, integrating GeoGebra into the HLT introduced a new issue: a GeoGebra-centric habit characterized by an excessive dependence on GeoGebra in solving geometric transformation problems
