Abstract

Art exhibitions as a means of displaying creative works require innovation in the interaction between visitors to artworks. Currently, the use of augmented reality (AR) in art exhibitions is increasingly relevant and attracts attention as an interactive medium. However, challenges in its implementation still exist, including the lack of visitor engagement and limited physical space. The proposed solution is to use the marker-based tracking method in AR, which allows the integration of artworks with the environment through visual markers. This method allows visitors to interact directly with artworks through their mobile devices. In this context, the marker-based tracking method uses physical and visual markers, such as images or certain objects, to trigger AR elements. Visitors can access additional content, such as information about the artwork, multimedia interactions, or dynamic visualizations, by pointing their devices at the specified markers. This creates a new dimension in art, allowing visitors to interact directly with artworks through additional digital layers. The result is increased visitor interaction and participation in art exhibitions, resulting in a more immersive and dynamic experience. This system is expected to broaden the appreciation of art, encourage discussion, and enrich the visitor experience. The main goal is to enrich the visitor experience in understanding, appreciating, and enjoying artworks through interactive and innovative technology. Thus, the use of AR in art exhibitions with the marker-based tracking method not only creates a creative and immersive experience, but also opens up new potential in connecting art and technology to create a richer and more memorable experience. The results achieved from this study are in the form of providing a deeper experience to visitors in a painting art exhibition.

Abstract

The problem in this study is that in the implementation of the MBKM program there are still many weaknesses and shortcomings, including the fact that currently Bina Insan University does not have its own system that can be used as an information media in providing the best service to students, the current system needed is a system with the application of the Md5 algorithm, the MD5 algorithm is one of the algorithms used to find out that the message sent has not changed while on the network, this system provides registration for each existing independent campus program so that all data will be centralized in one system, on the other hand, the MBKM section also requires a system that can convert credits to programs that have been followed, where in the program each student is given the right to get a conversion of 20 credits or the equivalent of one semester. The results of this study are that with this application, it can facilitate the MBKM in processing and converting the MBKM program, as well as speeding up and streamlining the registration process and converting MBKM program values ​​and providing information to students and lecturers about MBKM.

Abstract

Virtual memory plays an essential role in contemporary operating systems like Windows 10, particularly in accommodating big data applications that need significant memory resources. This study seeks to evaluate how virtual memory optimization affects system performance using experimental techniques. Evaluations were performed utilizing benchmark software like Cinebench R20 and Unigine Heaven to assess the performance of the GPU and CPU. With virtual memory activated, the findings indicate a rise in data processing by 5-10% and a notable decrease in application response time. These findings hold significant consequences for application developers and users of systems with limited resources, since virtual memory can enhance physical memory capacity and improve overall system performance.

Abstract

Environmental health needs to be a major concern, such as air pollution which results in environmental pollution. That currently 90% of humans do their activities in closed spaces. Air cleanliness in closed spaces is important because it has a direct impact on human health. The aim of this research is to design a Remote Control and Microcontroller Based Disinfectant Fogging Spray Machine System. This tool will use Arduino – Nano as a Microcontroller and Remote Control as a driver and a Wireless IP Camera to monitor the work tool. This tool will require an NRF24L01 PA LNA 2.4Ghz as a detector signal transmitter at a distance of 10cm, an Oled LCD as an output and a GY - 906 temperature sensor that will measure the voltage and temperature that will be used by the tool. Testing CCTV cameras by controlling the Smartphone to find out the distance of the object to be sprayed. And controlling the tool via smartphone, to avoid dangerous areas. The Disinfectant Fogging System uses a CCTV camera system so that it can detect the distance to be sprayed and the cellphone will display an image or video. The remote control will hold or direct what will be sprayed, so that the disinfectant machine will release disinfectant fogging spray liquid.

Abstract

The increasing population of stray cats in urban areas demands innovative solutions to support a more efficient and transparent adoption process. This study aims to develop a web-based cat adoption application using the ReactJS framework and the Agile approach. In the development process, PIECES (Performance, Information, Economy, Control, Efficiency, and Service) analysis is used to identify system requirements and evaluate application performance. The Agile method is applied to enable iterative and adaptive development according to user needs. The ReactJS framework was chosen because of its ability to build responsive and interactive user interfaces. This application is equipped with cat gallery features, adoption profiles, adoption status tracking, online donations, and volunteer registration. The test results show that the developed application is able to increase the efficiency of the adoption process by up to 40%, increase user satisfaction based on the User Experience Questionnaire (UEQ), and support transparency in shelter management through donation and volunteer management features. PIECES analysis provides important insights to improve the performance and service aspects of the application. This application not only simplifies the adoption process but also increases public awareness of animal welfare equipped with adaptive and user-based features that integrate technology to support more effective and sustainable animal adoption.

Abstract

Cryptography is a field that is really needed in the current era of globalization where security and confidentiality of information are very difficult to maintain considering wide and open communication access. Cryptography currently has a variety of methods and techniques which are divided into two categories, namely symmetric cryptography and asymmetric cryptography where their use depends on needs and conditions. The Merkle Hellman Knapsack method is an asymmetric cryptography method that uses a public key and a private key so that tapping and cracking becomes more difficult due to the use of different keys both during encryption and during decryption. Application development using the Merkle Hellman Knapsack method generates public keys and private keys using super increasing and inverse modulo series values, making the cryptanalysis process more difficult. The system developed is able to provide an alternative in securing text data.

Abstract

In computer networks, routing protocols play an important role in determining the best path to send data packets. Enhanced Interior Gateway Routing Protocol (EIGRP) is a routing protocol based on the Distance Vector algorithm that is widely used because of its ability to quickly converge and efficiently use network resources. However, the problems faced by EIGRP performance in various network scenarios, such as topology changes and traffic density, are still challenges that need further analysis. Therefore, this research aims to analyze the Quality of Service (QoS) in EIGRP routing based on main parameters such as delay, throughput, packet loss and jitter. The method used in this research involves network simulation using simulation software, where scenarios with various variations in network topology and load are tested to evaluate EIGRP performance. The main contribution of this research is to provide deeper insight into the effectiveness of EIGRP in supporting optimal Quality of Service in various network conditions. Interim results show that EIGRP is able to provide stable performance in networks with minimal topology changes, but experiences increased delay and packet loss in high traffic conditions. It is hoped that this research can be a reference for network administrators in optimizing the use of EIGRP to support better network performance.
