Abstract

Indonesia is an agrarian country with an environment that strongly supports agricultural processes. Because of this, crops are one of Indonesia’s main commodities and choosing a right crop to cultivate becomes a crucial process. Nowadays, lots of recommendation system has been made to help with decision making. A crop recommendation system is one of them and prove to be helpful in helping farmers decide what crop to plant based on the condition of the environment. An idea of implementing particle swarm optimization on a crop recommendation system occurred. Particle swarm optimization can be implemented to choose the presumably best parameter for a Gaussian Naïve Bayes model. The result of implementing particle swarming optimization to find the best smoothing parameter is the accuracy of the model reaching 99.5%. However, this is not different to the result of the model without particle swarm optimization which reach the accuracy of around 99.5% too.

Abstract

As a response to increasing safety and efficiency problems, utilizing the Package Tracer simulation, this research aims to create a smart garage that provides a new solution to the public to provide warnings to avoid fires, vehicles are not left in closed garages for too long so that things don't happen. dangerous things and to increase garage efficiency. This research uses experimental and quantitative methods, which are the methods used to design a system. With this system, garages will avoid theft and fires to quickly apply sensor advances in various situations, with a focus on vehicles that stay too long in the garage and smartphone-enabled garages, which is an important problem in many homes. Utilizes Packet Tracer simulation, emphasizing factors such as placement, sensitivity settings, and effective use. This article provides valuable insight into potential opportunities for future research and innovation in the field of smoke detection. This research highlights the importance of proper use and maintenance in maximizing the capabilities of smoke detectors.

Abstract

This study aimed to design an interface for the Soul Notes application using design thinking methodology, focusing on mobile-based applications. The study employed a qualitative approach, involving 5 participants who were asked to use the application and provide feedback. The results showed that the participants found the application easy to use and appreciated its features, such as mood tracking and relaxation techniques. The study also found that the participants valued the application's ability to provide a platform for expressing emotions freely and securely. The results of the study were analyzed using the Single Ease Question (SEQ) method, which indicated a high level of ease of use, with an average score of 6.52 out of 7. The study's findings suggest that the Soul Notes application can effectively support mental well-being and emotional management, and that its design should prioritize user experience and security

Abstract

The advancement of Internet of Things (IoT) technology has significantly contributed to various aspects of modern life, particularly in smart home applications. One essential feature of a smart home is a remote light control system that enables users to manage household lighting more efficiently. This research simulates an IoT-based light control system using Cisco Packet Tracer, focusing on the design and implementation of a smart home network topology. The system consists of a Wi-Fi router, multiple smart lights, and a smartphone as the primary control device. The methodology includes network topology design, device configuration, and communication testing to evaluate system performance. The test results indicate that the system successfully operates according to the predefined scenarios, where smart lights respond to commands from a smartphone quickly and reliably via a Wi-Fi network. Additionally, the system demonstrates stable communication between IoT devices, even under network variations. This simulation highlights the potential of IoT-based light control systems in enhancing energy efficiency and providing greater convenience in home automation. Future research can expand this system by integrating sensor-based automation and cloud connectivity to improve flexibility, security, and scalability.

Abstract

The decline in children's interest in learning due to easy access to games is the main reason I designed game-based learning. To make learning more engaging, presenting materials in an interactive way is essential. Game-based learning addresses this issue by packaging educational content attractively, increasing children's interest in learning. This game will introduce the world of IT to children, particularly cyber security. One key concept is cryptography, using the Caesar cipher algorithm due to its simplicity and suitability for children. The Caesar cipher enables both encryption and decryption processes, making it perfect for teaching cryptography basics. By designing the game as an interactive mystery, it aims to enhance children's learning interest and introduce them to cyber security effectively, making learning both fun and educational.
