Batik culture is very strong in Indonesia, this is the reason that batik can be found throughout the archipelago, with unique characteristics that distinguish it in each region. However, people are often confused and find it difficult to recognize one type of batik from another. One of the famous types of batik motif is Batik Parang. This research aims to establish a Convolutional Neural Network (CNN) model to classify Batik Parang and help people distinguish it from other batik motifs. Deep learning, particularly CNN, was chosen because it has a high accuracy rate in image classification. A quantitative Experimental design is used, using a dataset of 100 batik images evenly divided into two classes, namely Batik Parang and not Batik Parang. The dataset is divided into two categories, namely training data and testing data, with a data ratio of 80:20. Thus, by using Convolutional Neural Network (CNN), the classification between Batik Parang and not Batik Parang produces an accuracy of 95%, with the use of epoch = 118 and batch_size = 100.

The Effect Of Use Of Lung Mask Fixation On The Accuracy Of Targeted Irradiation In Lung Cancer Intensity Modulated Radiation Therapy (Imrt) Technique In The Department Of Radiation Oncology, Jakarta General Hospital. Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. While normal cells in the lungs usually develop and reproduce to form healthy lung tissue, these abnormal cells actually reproduce more quickly and are never able to become normal lung tissue. As a result, lumps of cancer cells are formed, which are often referred to as tumors. (4) Radiotherapy is a form of therapy that has been proven to be useful in treating cancer. The aim of radiotherapy is to provide safe, accurate and efficient radiation doses to treat various types of cancer and also non-malignant disorders (7). Carrying out radiotherapy for lung cancer involves the use of immobilization devices, one of which is a thermoplastic mask. This mask functions to reduce the patient's body movements, including movements caused by breathing (9). Verification is a critical stage in the radiotherapy process. The purpose of this verification is to ensure that there are no significant differences in the exposure carried out (14). Giving the right dose of radiotherapy radiation is very necessary to achieve successful therapeutic treatment. The accuracy of dosing and the accuracy of the patient's position influence the dose distribution that will be received by the patient. This verification is based on the International Atomic Energy Agency (IAEA) Human Health Series No. 31 of 2016 with a displacement value of 0.3cm (15). EPID (Electronic Portal Imaging Device) is an additional device connected to the LINAC (Linear Accelerator) radiotherapy device. EPID functions as a verification tool for radiation dose and geometry which is very important in the radiotherapy process (16). The accuracy of the patient's position during radiation treatment greatly influences the accuracy of the IMRT technique. Before irradiation, verification is carried out using an EPID (Electronic Portal Imaging Device) to ensure the correct target position on the tumor. This helps measure the x, y, and z axis coordinates along the radiation area before the radiation procedure begins.

Butterflies’ recognition serves a crucial role as an environmental indicator and a key factor in plant pollination. The automation of this recognition process, facilitated by Convolutional Neural Networks (CNNs), can expedite this task. Several pre-trained CNN models, such as VGG, ResNet, and Inception, have been widely used for this purpose. However, the scope of previous research has been somewhat constrained, focusing only on a maximum of 15 classes. This study proposes to modify the CNN InceptionV3 model and combine it with three data augmentations to recognize up to 100 butterfly species. To curb overfitting, this study employs a series of data augmentation techniques. In parallel, we refine the InceptionV3 model by reducing the number of layers and integrating four new layers. The test results demonstrate that our proposed model achieves an impressive accuracy of 99.43% for 15 classes with only 10 epochs, exceeding prior models by approximately 5%. When extended to 100 classes, the model maintains a high accuracy rate of 98.49% with 50 epochs. The proposed model surpasses the performance of standard pre-trained models, including VGG16, ResNet50, and InceptionV3, illustrating its potential for broader application.

Abstract.Network anomaly detection is a situation that occurs in network traffic that causes conditions to become abnormal. This research aims to analyze the performance of various machine learning algorithms in network anomaly detection and compare the performance of single classifier algorithms with ensemble learning. This ensemble learning technique has advantages such as increased accuracy and performance, can reduce the risk of overfitting and underfitting by using different subsets and features of data, and can turn weak learning into strong learning. However, on the other hand, this ensemble learning technique also has disadvantages in its use, namely that this ensemble method may not work well with high variance models, as the ensemble method may not be optimized for anomaly detection and that this method can be computationally expensive and time consuming due to the need to train and store multiple models. Some of the techniques used are deep learning, eager learning, lazy learning, bagging, feature selection, boosting, and stacking. In addition to this, this machine learning algorithm has weaknesses, including if any of the data used is incomplete, it will result in inaccurate completion data, making the programming process quite time-consuming. This research can help develop a more effective and efficient network anomaly detection system. The results of this research show that using ensemble learning and feature selection techniques can improve anomaly detection performance by reducing the processing time of redundant data and classification, as well as increasing precision values.
