The reality shows that there are still teachers who do not have role models, especially in terms of pedagogy. Teachers often start lessons late for various reasons. This problem was discovered by researchers at SMP Negeri 1 Juwiring. After the questionnaire is distributed to respondents (students), the names of teachers who are often late will be collected. One way to overcome this problem is to provide training to increase teacher motivation to come to class on time. In this training, the Reward and Punishment method was applied with a positive work culture. When teachers (participants) have achieved the specified indicators, they will receive a reward, while teachers who have achieved the indicators will receive a punishment. The indicator of success in this research is that 100% of participants always arrive on time when starting lessons. This research uses the spiral method from Kemmis and Taggart. Kemmis and Mc model action research design. According to Taggart, there are four stages of action research, namely planning, action, observation and reflection. The data collection instruments were in the form of observation sheets for researchers and assessment sheets for participant attendance levels. The results of the research were that after carrying out positive culture training at SMP Negeri 1 Juwiring in cycle I, none of the participants had completed it. There is no participant who has succeeded 100% in not being late, but there is 1 participant whose accuracy level has reached 93%, this means that the participant has experienced improvement. Meanwhile, the accuracy rates for the other 4 participants ranged between 55%, 58%, 2% and 77%. After carrying out cycle II while continuing to use Reward and Punishment with a positive culture, 5 participants completed it.

The purpose of this study is to discuss and find out about the concept of accountability in contemporary educational institutions. This research method uses literature review, by studying from literary sources that are relevant to the material discussed. Accountability is the obligation to provide accountability for a mandate or responsibility assigned to related parties, especially the party providing the mandate. The application of accountability in educational institutions is a must to increase public trust in educational institutions. Forms of implementing accountability in contemporary educational institutions include: Decisions must be made in writing and available to every citizen who needs them, accuracy and completeness of information, explanation of policy objectives taken and communicated, feasibility and consistency, and dissemination of information regarding a decision. One of the accountability models applied in contemporary educational institutions is administrative accountability, which includes traditional accountability, managerial accountability, program accountability and process accountability.

One mathematical model in the form of a system of nonlinear ordinary differential equations is the predator-prey model. The predator-prey model explains population changes of one prey population and one predator population due to changes in time. The radial basis function network method is used to find a numerical solution to the predator-prey model. The radial basis function network method can directly approximate the function and derivative of the prey-prey model using a basis function. The basis function used is a multiquadric basis function. Numerical solutions using the radial basis function network method obtained from this research show high accuracy and low error. The absolute error obtained from the two simulations with Δt = 0.01 each is 0.0066 in the first simulation and 0.022 in the second simulation. The errors obtained are relatively small because each only represents 0.66% of the initial value of the first type and 0.5% of the initial value of the second type. This shows that the radial basis function network method is efficient in calculating the predator-prey model solution.

Convolutional neural network (CNN) is a deep learning (DL) model that has significantly contributed to medical systems because it is very useful in digital image processing. However, CNN has several limitations, such as being prone to overfitting, not being properly trained if there is data duplication, and can cause unwanted results if there is an imbalance in the amount of data in each class. Data augmentation techniques are used to overcome overfitting, eliminate data duplication, and random under sampling methods to balance the amount of data in each class, to overcome these problems. In addition, if the CNN model is not designed properly, the computation is less efficient. Research has proved that data augmentation can prevent or overcome overfitting, eliminating duplicate data can make the model more stable, and balancing the amount of data makes the model unbiased and easy to learn new data as evidenced through model evaluation and testing. The results also show that the custom convolutional neural network model is the best model compared to ResNet50 and VGG19 in terms of accuracy, precision, recall, F1-score, loss performance, and computation time efficiency
