No full textpplying the right training methods can lead to optimal athlete performance. The use of one training method is common, and the use of a combination of two training methods is something new in training. The purpose of this study was to reveal the effectiveness of the combination of split jump training as a plyometric exercise with short sprint training on the leg muscle power capacity and agility of volleyball players. The research method in this research is a quasi experiment involving 40 samples (age: 20.85 ± 0.89 years, height: 178.69 ± 6.51 cm, and weight: 72.47 ± 8.02 kg). This study used a modified randomized pre-test and post-test design without a control group. The population of this study were volleyball players at Universitas Pendidikan Ganesha (Undiksha). Purposive sampling was chosen to determine the sample, namely 40 male student players.The sample was given training combining split jumps with short sprints for 4 weeks with details of 12 training sessions (3 times a week). The Jumpa DF and agility t-test were chosen as instruments to measure leg muscle power and agility. The collected data was analyzed using a paired t-test with a significance level of 5%. Before testing the hypothesis, start by testing the normality of the data using the Kolmogorov-Smirnova test and the homogeneity of the data using Levene\u27s with the help of SPSS 16.0. The results achieved show that there is a significant influence on the leg muscle power (sig \u3c0.05) and agility (sig \u3c0.05) of volleyball players. Based on the results of this data analysis, it can be concluded that the combination of split jump and short sprint training for 4 weeks has a significant effect on the results of leg muscle power and agility in male volleyball players. Seeing the findings above, it is hoped that volleyball coaches can apply this training method, specifically in the pre-competition phase, which requires a short time to improve leg muscle strength and agility at the same time

Classification of Corn Seed Quality using Residual Network with Transfer Learning Weight
No full textCorn is one of the main ingredients in farm animal feed. Currently, corn is preferable because widely available and cheaper in the market than others. However, it needs quality control on corn production. The company that manufactures animal feed has certain quality standards to receive corn material. On the other hand, the quality of corn produced varies greatly. Thus, quality control when receiving corn from suppliers greatly affects the quality of animal feed. The quality of feed ingredients is classified into physical properties and analytical values. Physical properties are determined so that the resulting corn can be accepted or rejected, while the analytical value is used as the basis for formulating the diet. The physical properties of corn are determined by the human senses, such as sight and smell, while the analytical value is by chemical analysis. Physical quality control by relying on human senses is certainly limited and takes time. Based on these problems, it needs to make a classification system of corn seeds automatically. This study uses corn seed images as classification data. The system uses public data from Naagar which consists of four classes: pure, discolored, silk cut, and broken. Image classification uses a Convolutional Neural network (CNN) with ResNet152v2 architecture. The hyperparameters used consist of a learning rate of 0.001, a batch size of 512, and an epoch of 25. Adaptive Moment Estimation (Adam) for the optimizer. Percentage of data training vs validation 80:20. The validation results show an accuracy of 65%, precision of 66%, and recall of 64%

No full textThis research aims to determine the effectiveness of the PhET-assisted creative problem solving model on creative thinking abilities and student learning outcomes in vibration, wave and sound materials. In this research, the samples taken were determined based on the characteristics of the two classes which were almost the same (homogeneous). The characteristics used are the average UAS scores of two classes which are close to the same and the science teacher who teaches in the same class. The sample chosen was class VIII with class A as the control class and class B as the experimental class with a total of 16 students in each class. This research uses an experimental method with a nonequivalent control group design. Data on students\u27 cognitive learning outcomes were taken using a test method in the form of 15 multiple choice questions, while students\u27 creative thinking abilities used a test method in the form of 5 descriptive questions which had been tested for validity and reliability with a significance level of 5%, resulting in rcount \u3e rtable. Research data was obtained from pretest-posttest scores and analyzed using the MANCOVA statistical test. The results of the multivariate analysis show that the sig value is \u3c0.05, namely 0.001 \u3c0.005, which means that there is a significant influence. The N-gain results show an increase in creative thinking abilities by 56.57% and an increase in students\u27 cognitive learning outcomes by 57.08% which is included in the medium category. Therefore, it can be concluded that the use of the creative problem solving model assisted by PhET significantly increases students\u27 creative thinking abilities compared to conventional learning. In addition, there is a significant increase in the cognitive learning outcomes of students who use this model. The implementation of PhET as an interactive learning tool opens up opportunities for students to understand science concepts in a more in-depth and contextual way. Implications of these findings include increased student engagement, development of innovative learning models, and emphasis on problem-based learning. This research contributes to educational practitioners and researchers in understanding the potential of the PhET-assisted creative problem solving model as a practical approach to improving students\u27 learning outcomes and creative thinking abilities in the context of science learning
