Abstract

Peningkatan volume dan kompleksitas transaksi keuangan digital mendorong meningkatnya risiko fraud yang bersifat dinamis dan adaptif. Penelitian ini bertujuan merancang Enterprise Architecture (EA) sistem deteksi fraud transaksi keuangan berbasis TOGAF ADM yang terintegrasi dengan model Deep Learning Long Short-Term Memory (LSTM). Dataset publik fraud detection dari Kaggle digunakan untuk memastikan reprodusibilitas penelitian. Model LSTM dievaluasi menggunakan metrik accuracy, precision, recall, dan F1-score. Hasil pengujian menunjukkan performa yang sangat baik dengan accuracy 99,25%, precision 96,40%, recall 92,80%, dan F1-score 94,55%. Integrasi LSTM dalam EA memastikan keselarasan antara kebutuhan bisnis, arsitektur data, aplikasi, dan teknologi. Penelitian ini tidak hanya menghasilkan model deteksi fraud yang akurat, tetapi juga blueprint EA yang terstruktur, scalable, dan siap diimplementasikan pada organisasi keuangan modern.

Abstract

Theuse of data mining techniques presently help business owners to facilitate the promotion of their product marketing. One of the most techniques is well-known as association analysis. This association analysis aims to find the relationship between the goods purchased by customers. This kind of association analysis is commonly known as market basket analysis. Market basket analysis uses customer data that has been stored in the database to find new information in it. The apriori algorithm, is applied an algorithm for conducting market basket analysis, which aims to find the most frequently purchased items. This apriori algorithm produces an association rule that is useful for business actors. By analyzing the association a priori algorithm can be seen that customers’ data can be used as input for business owners to determine sales strategies for their business.

Abstract

The title of this research is the analysis of the thesis theme clustering algorithm using the k-means method. The main problem is how we can find out which theme is most in demand by thesis students at the Faculty of Engineering, University of Muhammadiyah Bengkulu. This clustering uses the K-means method. The K-Means method was chosen because this method is one of the non-hierarchical data clustering methods that seeks to partition data into two or more clusters with the same characteristics included in the same cluster. The purpose of this research is to help prospective students who will write their thesis in knowing which themes are more interested in them.

Abstract

The development of technology is currently growing very rapidly which allows us to access various kinds of data and information, but there are lots of people who abuse this ability, for example phishing activities that often target data and information owned by individuals and companies. Loss of data and information is very detrimental to individuals and companies, where the data and information can be used as a tool for extortion, used as a fraud tool and even the information can be traded. The main reason for the importance of maintaining the security of information is to protect information from online crimes. One of the techniques designed to protect important and confidential information is a cryptographic technique using the Blowfish algorithm and also a QR Code which functions as second line security. where data and information that has been converted into a QR Code cannot be changed. The purpose of this study is to apply the Blowfish Algorithm for Encryption and Decryption of the QR Code into an android-based application system. The results of this study are: The blowfish algorithm can be implemented into an android-based application. Plaintext which is converted into ciphertext using the blowfish algorithm can be used as a QR Code using a QR Code generator. A QR code is up to 7089 numeric digits and 4296 alphanumeric characters. The amount of information will affect the QR Code module, so the symbols in the QR Code will become more complicated. This application has received an assessment from respondents from users with an average value (6.5) with the category of choice "agree".

Abstract

Rendering is the final stage of the modeling or animation process. It is during this rendering that the polygons that make up a model will be computed on the computer to form an image. Along with the times, there are many rendering provider applications for 3D animation, one of which is Mental Ray. The formulation of the research problem is How long does it take to render a 3D animated film using mental ray and analyze the size of the rendered using mental ray? The development model in this study uses the Multimedia Development Life Cycle (MDLC) development which is the Luther version of the development method. Data collection by taking two finished or ready-to-rendering 3D films. The results show that the average length of time needed to render of The Little Human animation is 8.3 minutes, while the animated film Go Alex is 8.8 minutes. While the average size of the 12 rendered scenes of The Little Human animation is 17.3 mb and the animated film Go Alex is 17.8 Mb. Computer specifications will affect the performance of the rendering engine itself. This test only uses one type of computer, so to really test the performance of the rendering engine, a similar test is needed using several different types of computers and sepsis. When using the Autodesk Maya 2019 application, it is recommended to use incrementalSave to find out every step of the changes made, because it is to remember the steps to be taken if you forget and anticipate unexpected things such as blackouts.

Abstract

Diabetes Mellitus is associated with long-term damage, dysfunction, and failure of various organs, especially the eyes, kidneys, nerves, heart, and blood vessels. Naive Bayes is a classification method that can predict the probability of a class, thus generating decisions based on learning data. The Naive Bayes method is used to classify Diabetes Mellitus. To predict a disease using a data mining approach, symptoms accompanied by clinical data are required. Therefore, the problem is formulated how the Naive Bayes method compares with Bayesian regularization neural networks for classifying types of Diabetes Mellitus. With the RapidMiner tool, it becomes educational information in providing information on Diabetes Mellitus based on Type 1 Diabetes, Type 2 Diabetes, and Gestational Diabetes

Abstract

The face recognition process aims to identify some of the basic requirements of the system and learn the techniques required for the development of a realtime face recognition system. Facial recognition is one of the pattern recognition approaches for the purpose of identifying a person's face with a biometric approach. In this case Haar Feature is one of the methods to identify face recognition, Haar feature is used to recognize objects based on the simple value of a feature, not the pixel value contained in the object image. In testing this system, it is known that the success rate in the Confusion Matrix calculation on the image is between the actual and predicted values with a Precission value of 93%, meaning that the level of accuracy between the information requested by the user and the answer given by the system is the same. Recall results from the Precission value tend to be inverse to the results of the Recall value. If the Precission result is small then the Recall result is large, because the success rate of the Recall system in finding back a given information is 98%. Precission and Recall results are not the result of Accuracy. The difference is the level of closeness between the predicted results and the actual results of Precission and Recall. Where the actual results are the results found / relevant (True Positive) and the absence of true results / not found (True Negative) and these results are calculated based on the results found. The prediction results that users want, then the result of Accuarcy is 93% which is obtained based on the addition of actual results divided by the prediction results.
