Pengembangan Fitur Absensi Pengenalan Wajah Menggunakan Model Facenet pada Aplikasi Buku Tamu Desa
The FaceNet model is one of the deep learning-based face recognition methods capable of transforming facial images into feature vectors (embedding) that represent the unique identity of each individual. In previous studies, this model is often combined with classification methods such as Support Vector Machine (SVM) or K-Nearest Neighbor (K-NN). Although accurate, these approaches require high computation and complex inference processes, making them less suitable for applications that require fast response and efficiency, such as real-time attendance systems. This research proposes an alternative approach using cosine similarity to compare similarity between face vectors. Cosine similarity measures the similarity of two vectors based on the angle between them, with values ranging from 0 (not similar) to 1 (identical). The system was developed by combining FaceNet and cosine similarity models, without any additional classification. Test results showed that faces registered in the system produced cosine similarity values between 0.83 and 0.96 (closer to 1 indicates a high match), with an average of 0.90, while unregistered faces had values between 0.42 and 0.67, with an average of 0.53. By setting the threshold at 0.7, the system successfully differentiated between recognized and unrecognized faces with 100% accuracy on 30 respondents. This approach significantly reduces the computational burden, enables implementation on devices with limited specifications, and provides a practical and accurate solution for face recognition-based digital attendance systems.

A Computational Enhancement Of Base64 Algorithm Using Residue Number System Algorithms
A significant part of information security has been played by cryptography techniques. Today's daily existence depends heavily on the advancement of data, information, and communication technologies. Consequently, there is a huge increase in the need for data and information. In communicating data over a public network, data security is a necessity that must be carefully taken into consideration. Thus, Base64 algorithm has been used in numerous security applications for ensuring data confidentiality, integrity and authentication. However, research shows that there is security vulnerabilities in most widely used Base64 algorithm due to the absence of key mechanism. To address this concern, this research employs residue number system algorithms for the enhancement of base64 algorithm because of its cryptographic features whereby strengthen the transformation of the existing base64 algorithm to produce a novel symmetric-based cryptographic algorithm. The developed algorithm generates a symmetric key by shuffling the original key with the textual data, making the transformation of each character of the data better each time it is shuffled. Therefore, the research bridges the security gap in Base64 cryptographic algorithm by factoring key mechanism of RNS based algorithm into the newly developed algorithm. In addition, the developed symmetric-based cryptographic algorithm is more robust than the existing Base64 cryptographic algorithm because of the planned pattern and confusion produced during the methodology procedure thereby safeguards the data more effectively as shown in the cipher text generated.

Performance Analysis of The Last Significant Bit (LSB) Method in Steganography for Data Hiding in Image Data
Technology as a means of conveying information can have significant implications for the security and confidentiality of data and information content. When a sender wishes to convey a message to someone and does not want the message to be easily visible, the concealment of this message becomes crucial for the sender. One commonly used method for data concealment is the Least Significant Bit (LSB) method in steganography. The LSB method is preferred for its simplicity, fast process, and greater capacity. Messages are embedded by replacing the least significant bit in the host image with the message bits, with the rule that the number of message bits does not exceed the number of bits in the host image. Based on research findings, the results of steganography are difficult to distinguish from the original content through visual observation. Therefore, it can be concluded that the steganography method is highly effective for concealing a message.

Analysis and Utilization of the Base64 Algorithm for Image Encryption and Decryption Security in Web-Based Images
Data is often the target of irresponsible people for misuse. The theft is done is to benefit from the person who has the data. In addition to theft of work files, theft is also carried out on image files. The purpose of this file theft is to find out what the image contains. Someone has a private image that cannot be known by others. Misuse of image files will be fatal for the owner of the image. Cryptographic techniques are needed in securing images and one of the methods used to secure these images is using the base64 algorithm. The Caesar Cipher algorithm can help users secure the image file. The Base64 algorithm can be used to change the ASCII 256 format to Base64 so that it is easy to send or store on a storage medium. By applying the Base64 algorithm to image files, the security and confidentiality of these files will protect data from irresponsible people.
Clustering Tweets Data on Twitter Social Media using K-Means Method
Twitter, as a popular social media with millions to billions of global users, stores a wide variety of information. This study focuses on the use of Text Mining to analyze tweet content through the application of clustering techniques, specifically using the K-Means algorithm. The implementation process involves several stages of text processing, including casefolding, tokenizing, stopword removal, and stemming. Feature extraction is performed to provide input for the K-Means algorithm. The clustering evaluation uses the Silhouette coefficient method. The test results show that different K values result in a variation of the silhouette value. In a particular test scenario, a value of K=2 resulted in a silhouette of 0.5000421, K=5 had a value of 0.0501051, and K=9 had a value of 0.501893. From these values, the data structure of the dataset taken can be categorized as medium structure, because the silhouette value is in the range of 0.5 to 0.7. These results show that cluster quality is influenced by the K value, with the silhouette value being the main determinant.
