In Indonesia, East Java is the largest corn producer. The first symptom of the disease in corn plants is marked by small brownish oval spots which are usually caused by the fungus Helminthoporium maydis, if left unchecked, farmers can suffer losses due to crop failure. Therefore it is important to provide treatment for diseases in corn plants as early as possible so that diseases in corn plants do not spread to other plants. In this study, the dataset used was taken from the kaggle website entitled Corn or Maize Leaf Disease Dataset. This dataset has 4 classifications: Blight, Common Rust, Grey leaf spot, and Healthy. This study uses the Convolutional Neural Network method with 2 different models, namely the EfficientNet-B0 and ResNet-50 models. The architectures used are the dense layer, the dropout layer, and the GlobalAveragePooling layer with a dataset sharing ratio of 70% which is training data and 30% is validation ...

Therefore, this study aims to classify fraudulent transactions. The proposed method is Ensemble Learning which will be tested using the Boosting type with 3 variations, namely XGBoost, Gradient Boosting, and AdaBoost. Then, to maximize the performance of the model, the dataset used is optimized with the Synthetic Minority Oversampling Technique (SMOTE) function from the Imblearn library in the data train to handle imbalanced dataset conditions. The dataset used in this study is entitled "Credit Card Fraud Detection" with a total of 284807 data which is divided into two classes: Not Fraud and Fraud. The proposed model received a recall of 92% with Gradient Boosting, where the results increased by 10.37% compared to...

Everyone's typing behavior is considered unique. One of the numerous approaches to secure private information is by utilizing a password. The development of technology is trailed by the human requirement for security concerning information and protection since hacker ability of information burglary has gotten further developed (hack the password). So that hackers can use this information for their benefit and can disadvantage others. Hence, for better security, for example, fingerprint, retina scan, et cetera are enthusiastically suggested. But these techniques are considered costly. The advantage of KDA is the user would not realize that the system is using KDA. Accordingly, we proposed the combination of Naïve Bayes and MHR (Mean of Horner’s Rule) to classify the individual as an attacker or a non-attacker. We use Naïve Bayes because it is...

Brain tumors have 4 grades, namely grades 1 to 2 are benign tumor grades, and grades 3 to 4 are malignant tumor grades. Therefore, early identification of brain tumor disease is very important in providing appropriate treatment and treatment. This study uses a dataset obtained through the Kaggle website titled Brain Tumor Classification (MRI). The number of data is 3264 images with details of Glioma tumors (926 images), Meningioma tumors (937 images), pituitary tumors (901 images), and without tumors (500 images). In this study, there are 4 scenarios with different testers. This study proposes the classification of brain tumors using Hyperparameter Tuning and EfficientNet models on MRI images.

This disease is caused by respiratory tract infections, ranging from the common cold to serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). In Indonesia, there are tests to detect COVID-19, such as PCR and Rapid Test. This detector takes a long time and is less accurate in producing a diagnosis. This study aims to classify chest X-ray images using CNN and Transfer Learning methods to diagnose COVID-19. The proposed model has 4 scenarios: CNN Handcraft Model, Transfer Learning (VGG 16, VGG 19, and ResNet 50). This model is accompanied by data augmentation and data balancing techniques using undersampling techniques. The dataset used in this study is the “Covid-19 (COVID-19 and Normal) Radiographic Database” with 13,808 data divided into two classes, namely COVID-19 and Normal.

New innovations in the classification and detection of skin cancer using artificial neural networks continue to develop to help the medical and medical world in analyzing images accurately and accurately. Researchers propose to classify skin cancer pigments by focusing on two classes, namely non-melanocytic malignant and benign, where the skin cancer category which is classified into the non-melanocytic class is Actinic keratoses, Basal cell carcinoma. While skin cancers that are classified into Benign are Benign keratosis like lesions, dermatofibrama, vascular lessions. The method used in this study is Convolutional Neural Network (CNN) with a model architecture using 8 Convolutional 2D layers which have filters (16, 16, 32, 32, 64, 64, 128, 128).

This research tried to develop an application using a social media as a medium for students to learn English more efficiently. This application was in the form of a chatbot (answering robot) and designed to be capable of replacing the teacher's role in answering students' questions while they learn English. Their familiarity with the interface and navigation of social media made them easy to operate the integrated chatbot. This application was tried out on D3 students of English Study Program, State Polytechnic of Malang. The test results showed 98% of the respondents stated that the chatbot helped them learn English, 90% said that the material presented was quite interesting, and 72% stated that the chatbot application did not decrease the performance of their mobile phones. This showed that the collection of information and the help model through...

This research tried to develop an application using a social media as a medium for students to learn English more efficiently. This application was in the form of a chatbot (answering robot) and designed to be capable of replacing the teacher's role in answering students' questions while they learn English. Their familiarity with the interface and navigation of social media made them easy to operate the integrated chatbot. This application was tried out on D3 students of English Study Program, State Polytechnic of Malang. The test results showed 98% of the respondents stated that the chatbot helped them learn English, 90% said that the material presented was quite interesting, and 72% stated that the chatbot application did not decrease the performance of their mobile phones. This showed that the collection of information and the help model through...

Seiring dengan perkembangan teknologi, juga memicu berkembangnya file-file jahat atau biasa disebut dengan malware. Aktivitas berbahaya yang diakibatkan oleh malware sangat merugikan bagi para korbannya, sehingga dibutuhkan cara untuk mengatasinya. Umumnya pendeteksian malware menggunakan metode signature-basedakan tetapi metode ini mudah untuk dikelabui oleh malware yang memiliki kemampuan polimorfik. Penelitian ini bertujuan untuk melakukan pendeteksian jenis malware Android secara Dinamis dan melakukanklasifikasi jenis malware menggunakan algoritma Support Vector Machine(SVM). Metode pada penelitian ini dibagi menjadi beberapa tahapan yaitu pe...
