Abstract

Telkom University through the Covid19 task force team urges all employees to comply with health protocols while in the campus environment. Facilities such as masks, hand sanitizers, temperature scanners, and gate sterilizers have been provided to protect the campus community. The entire campus community is encouraged to isolate if there are symptoms of a Covid-19 virus attack. This Vending Machine was developed to provide health protocol facilities in the campus environment with the support of interactive multimedia technology. The development of this tool uses the Prototyping method which focuses on the main functions. The result of the Vending Machine development is that transactions can be used through the Android mobile application device directly through the desktop application contained on the screen at the Vending Machine. The results of the Vending Machine test state that 100% of the functions run according to the procedure and the device User Interface gets a value of 76.9 from the System Usability Scale test method.

Abstract

Artificial intelligence in a game plays a vital role in enhancing the player's gaming experience, especially in single-player games. NPCs are the primary means of interaction in single-player games, assisting and guiding players like interactions with other players. Chaos Crossing requires pathfinding technology for optimal NPC movement, allowing them to navigate the environment grid-based while avoiding static obstacles. The Dijkstra algorithm and the A-Star algorithm need to be compared because, based on previous research, the Dijkstra algorithm has proven effective for calculating the shortest distance to the destination point in a static environment based on a two-dimensional grid with characters moving in it, as well as the A-Star algorithm can avoid a static environment based on grid and is used to determine the shortest distance to the destination point in the character's movement. This quantitative research aims to find a solution that optimizes NPC movement by testing and comparing Dijkstra's and A-Star's algorithms in a static environment grid based on the game Chaos Crossing. The test results and comparative analysis show that the A-Star algorithm performs a faster route search with an average value of 36.37 seconds than Dijkstra's algorithm with an average matter of 20.76 seconds and utilizes memory more efficiently with an average value of 20.19 MB than Dijkstra's algorithm with a value 22.17 MB on average. However, Dijkstra's algorithm produces a slightly shorter track distance, with an average value of 42.26 units, compared to the A-Star algorithm, with an average value of 42.39 units.

Abstract

Improving localization accuracy and reducing development costs are pivotal keys and main issues in managing and administrating wireless sensor networks (WSNs). This paper considers a modern and qualified algorithm that leverages advanced optimization techniques to localize nodes deployed in outdoor environments. The proposed algorithm, named Intelligent Water Drops with Simulated Annealing (IWDSA), combines two powerful optimization methods: Intelligent Water Drops (IWD) and Simulated Annealing (SA). IWD is a qualified stochastic optimization tool adept at minimizing objective functions. In IWDSA, SA is integrated to enhance solution quality and prevent IWD from getting trapped in local minima. This paper ensures that internal distances between nodes are calculated using Received Signal Strength Indicator (RSSI) measurements. The paper aims to achieve two primary goals. First, it addresses the challenge of low accuracy in RSSI measurements by employing IWDSA. Second, it aims to achieve highly accurate localization of unknown sensor nodes in WSNs. IWDSA enhances localization precision due to its flexible implementation of IWD and SA, combined with the cost-free utilization of RSSI. Simulation results demonstrate the reliable performance of the proposed algorithm in solving the low accuracy of RSSI measurements and localizing unknown nodes with high accuracy. Additionally, simulation results confirm that the proposed algorithm IWDSA exhibits outstanding performance compared to other algorithms utilizing optimization techniques, including genetic algorithms, bat algorithms, ant colony optimization, and swarm optimization. This exceptional performance is evident across various evaluation metrics, including localization error, localization rate, and simulation runtime.

Abstract

Currently, there are many applications of technology-based financial funding, and some have even been legalized by the Financial Services Authority (OJK), which is called fintech. In reality, it is still burdensome for business actors because of the difficulty in paying the installments that must be borne, whereas the business will have funds only if the goods they are selling are sold. In the Siliwangi University campus environment, students are required to take entrepreneurship lectures. So far, the learning process activities have only been in the form of concepts and theories; this has become an obstacle to field practice. In the field of entrepreneurship, these students become business actors. However, there is a difficulty in practicing entrepreneurship since students' capital is limited. On this issue, the campus is obliged to facilitate the creation of an entrepreneurial learning process as an investor. To connect the entrepreneurship learning process, information technology is needed. The application is intended to assist in the process of providing business capital by applying the concept of Islamic economics, namely the Islamic peer to peer financing model. This model provides flexibility between business actors and investors in providing financial assistance with potential profits and losses shared together. Based on the above problems, to support student entrepreneurship programs, it is necessary to apply financing for entrepreneurship program assistance based on the Islamic peer to peer financing model. From the results of testing the application can be applied to support the student entrepreneurship learning process based on the respondent's score of 82.08333 which indicates that the System Usability Scale value for this application is Acceptable.

Abstract

As one of the most widely spoken languages globally, English plays a pivotal role in academia, digital communication, and numerous professional domains. English proficiency is vital for academic pursuits, international communication, and careers. The profound impact of artificial intelligence on our daily lives is exemplified by techniques such as chatbots and speech recognition. Leveraging these techniques (i.e., Chatbot and speech recognition), the paper aims to create a user-friendly mobile app to enhance English-speaking proficiency at minimal cost. This study employs three conversational AI models- ChatGPT, Blenderbot, and DialoGPT as chatbots, and uses Google's speech-to-text/text-to-speech models for voice recognition and generation. The developed app and the used models are evaluated through questionnaires and response time measurements, highlighting user satisfaction with the system's realism, accuracy, and user-friendliness. ChatGPT and Blenderbot emerge as top performers in response quality, while DialoGPT excels in response speed.

Abstract

This research focuses on the design of a two-dimensional-based control system using Roblox Studio, a metaverse platform that has been proven to provide learning facilities in engineering. This research is conducted using two testing methods: direct testing in the Roblox application and testing using the Black Box testing method in the Roblox Studio. The testing is performed step by step, starting from testing user interactions with the system, testing GUI's ability to respond to user inputs, testing the ability to implement mathematical functions and display them in text form, and testing Roblox's capability to display these functions in simple graphic form. The design results can then be tested by analyzing the system's output in the form of mathematical calculations and how these results are shown through the designed two-dimensional interface. There is no direct correlation between mathematical calculation results and the aesthetics or comfort of the systems' GUI. Errors in such simple mathematical operations can be one factor in the occurrence of errors in open-loop systems. Roblox is highly recommended to provide more dynamic functions on BillboardGUI so that developers can have more options in their design activities.
