Abstract

The Javanese script as an Indonesian cultural asset must be preserved and disseminated to the current generation so that it is not increasingly lost from memory. Augmented reality (AR) technology has the opportunity to be used in developing interesting applications, because the nature of the technology that combines the real world with the virtual world can attract young people to use it in their daily lives. The chosen AR development method is the Multimedia Development Life Cycle method, and the software tools used are Unity and Vuforia. As a first step, a collection of marker images has been carried out from the segmentation results of the Hamong Tani manuscript on page 2. From the test results on Javanese script objects, it was found that the AR application functions properly and correctly on Javanese script images with the smallest size of 2x2 cm, and the largest at 11x11 cm. For the smallest font size, the distance from the camera to the Javanese script is a minimum of 5 cm and a maximum of 9 cm, while for the largest font size, the distance is a minimum of 18 cm and a maximum of 46 cm.

Abstract

WhatsApp is an application that is very well known in Indonesia and the world. The WhatsApp application is also known to be one of the applications with the most users to date. This application can make it easier for us to communicate remotely to help with work matters. With the many conveniences provided by WhatsApp in terms of communication, there are many modes of crime that use WhatsApp as a tool to commit digital crimes, one of which is WhatsApp Scam. One of the actions that can be taken to find out the perpetrators and how the perpetrators commit fraud is by digital forensics investigation. Digital forensics is a part of forensic science with the scope of material (data) investigations and discoveries on digital devices such as smartphones, computers, tablets, storage, and other networked devices. It includes the application of informatics for the presentation of evidence data from computer crimes that can assist the court in cybercrime evidence with a focus on maintaining integrity and maintaining a tight chain of custody. The D4I framework is expected to improve the implementation of digital forensics investigations at the stage of examining data and analyzing existing data. The investigation was carried out by combining the National Institute of Standards and Technology (NIST) method and artifacts from the cyber kill chain (CKC) to assist in the digital forensics process.

Abstract

Peeling coconut fiber generally still uses traditional equipment and some also use machines. After peeling coconuts, farmers always re-count the coconuts that have been peeled, where farmers often miscalculate the results of coconuts that have been peeled. From this problem, a tool is needed to count coconuts that have been peeled. This tool aims to help peel and count the number of coconuts that have been peeled. This tool will use an infrared sensor as a detector to count coconuts that have been peeled by a coconut fiber peeling machine. In the tool system, an Arduino Uno ATMega328 microcontroller is used to control the counter system and the research results will be displayed on a 16x2 LCD in the form of the number and maximum limit of coconuts that can be detected. The tool is designed to use a 7.4 V battery as the energy source for the tool and a buzzer as an indicator that the coconut passing through the sensor is detected. Farmers can set the limit of coconuts that will be counted by pressing the number on the keypad as desired. In the designed tool, the maximum number of coconuts that can be counted is 3000 coconut.

Abstract

Keyword Extraction is the process of identifying and extracting key words or important phrases from a text or document, aiming to quickly identify keyword information from a large amount of data. This research investigates three online news sites in Indonesia, namely Kompas.com, Detik.com, and Tempo.co. The keyword extraction process is strengthened by the TF-IDF (Term Frequency - Inverse Document Frequency) method, assigning a high weight to words that frequently appear in one document but rarely in others. The TF-IDF calculation results in different weights for each word. Many words were successfully extracted from the three sites, displaying 30 keywords from the dataset. The accuracy of the weight calculation was then tested using F1-Score, resulting in an F1-Score of 99.67%, with an accuracy rate of 99.76%.

Abstract

In the advancing digital era, digital data security has become a primary concern alongside the increasing cyberattacks and data breaches in line with the growth of information technology. The estimated global losses due to cybercrime, reaching trillions of dollars in 2023, exacerbate this phenomenon. One of the technologies that has been legally recognized in Indonesia since 2008 to safeguard digital data security is digital signatures. In the implementation of digital signatures, several cryptographic algorithms are used, such as ECDSA, EdDSA, and RSA. Although previous research has compared the performance of these three algorithms, attention to their practical applications, especially in the context of multi-signature, remains somewhat limited. Therefore, this research employs an experimental method with a quantitative approach. Within the scope of this study, signatures were applied to documents of varying sizes using the ECDSA, EdDSA, and RSA algorithms. Encryption and decryption time data were analyzed to determine the algorithm with the best performance. The research results show that ECDSA excels in terms of time performance, with an average time of approximately 0.001052 seconds. Hence, ECDSA was chosen for implementation in the multi-signature digital signature system for PDF document

Abstract

With advances in information technology, libraries are experiencing significant digital transformation. In addition to the migration of physical books to digital format, the development of advanced library systems allows unrestricted access. However, with the diversity of books available, users cannot navigate the type of book to borrow next. This problem can be solved with a recommendation system approach using the Apriori algorithm. This algorithm helps in identifying patterns that appear regularly in data, such as relationships between items in a transaction database. Data is collected from lending transactions, and through a pre-processing process to produce consistent data, the system implements the Apriori algorithm with minimal variation in support values. and minimum confidence. The results of model evaluation based on the minimum support value (0.02 to 0.07) show a decrease in the number of frequent itemsets and rules along with an increase in the minimum support value. Meanwhile, testing is based on the minimum confidence value. An increase in the minimum confidence value from 0.1 to 0.5 causes a decrease in the number of rules and frequent itemsets, indicating increasingly strict association rules. However, when the confidence value decreases from 0.3 to 0.4, the number of itemsets and rules remains constant.
