Abstract

The purpose of this research is to design over the air programming mechanism for a node in wireless sensor network. Data are gathered from experiments of the proposed system on a constrainted environment. On this design, the Arduino that becomes the target of reprogramming has it’s bootloader modified to enable the capability to run embedded program from the SD Card. Arduino’s source code .ino file is compiled into a .hex file using the Arduino IDE. Then, it is processed using avrdude application into a ready to run firmware binary file on Arduino. A desktop application is made for this mechanism in order to control sender XBee device in transmitting data packet by packet. If the transmission was successful, the node will restart itself, and trigger the bootloader to load new program from the SD Card. The system is evaluated through preset scenarios which including testing at various distances and environments (indoor and outdoor). It was concluded that the reprogramming mechanism was uneffective in transmitting source code when at least one of the XBee devices is located inside the building which affected the transmission process. For the second testing scenario, both nodes were located outdoors with testing distance up to 15 metres, resulting with average transmission speed of 35 bytes per second for sent packet size of 60 bytes. The safest sent packet size to avoid packet loss while transmitting should not exceed 30 bytes for transmission distance up to 15 metres. Transmission speed across all test scenarios ranges between 14 bytes per second to 35 bytes per second. For indoor testing, the evaluation results showed that the designed OTAP mechanism in this study is not yet effective. This is assumed to be influenced by the transmission capability of the XBee communication module.

Abstract

Blind individuals face obstacles in identifying objects or things around them, so a tool is needed that can help overcome these obstacles. This study aims to design an Arduino-based Hand Glove prototype that can help blind people identify objects around them. Research data collection was carried out through literature studies and testing of the designed prototype. The system is designed to consist of two large parts, the first part is the hand glove used by blind individuals, consisting of Arduino, RFID reader and speaker. The second part consists of objects to be identified that have been given an identity label in the form of a RIFD Tag. The evaluation results show that the design prototype can read and identify objects such as chairs, tables, laptops, cellphones and PCs which are distinguished from the sound variations that have been set and defined using a buzzer as a notification tool.

Abstract

This study aims to design an efficient calorie counter application using Model-View-ViewModel (MVVM). The use of the Model-View-ViewModel design pattern is based on efforts to facilitate the process of reusing source code (Reusability). The design process uses flutter as an application framework. This research can be used as a reference regarding the Model-View-ViewModel, as well as providing new knowledge for researchers regarding the combination of the Model-View-ViewModel design pattern with the flutter framework on the android platform. Data collection in this study was carried out through literature studies and evaluation of the system design. The application was developed using the Dart programming language, while the evaluation of the implementation of MVVM design pattern is measured by using CK metrics. The evaluation shows that the MVVM calorie counter application can be run on Bluestacks Android Emulator successfully. The reusability degree of the application is better than the non-MVVM calorie counter apps, where the WMC parameter decreased by 4.5 points, and the DIT parameter by 0.3 points, while the CBO parameter decreased by 0.4 points, and the LCOM parameter by 31.2 points. The results indicate that the MVVM calorie counter application is easier to maintain.

Abstract

Visual novels are a genre of video games that emphasized the delivery of interactive narratives, where players engaged with the storyline through a series of choices that influenced its direction and outcomes. In the development of Mystic Pages, a mystery-themed visual novel, challenges were encountered in managing branching storylines. Conventional methods such as if-else structures and flag systems were found to be inefficient and prone to logical errors when applied to large-scale scenarios. Therefore, this study aimed to implement a Finite State Machine (FSM) as a solution to manage dynamic and structured narrative flows. The storyline was represented as states within an FSM diagram, starting from the “start dialog” state to the “dialog pack end 5” state, with narrative progression determined by player choices. The results demonstrated that the documentation and visualization of Mystic Pages’ branching storylines using FSM facilitated modifications, as developers only needed to add new states and transitions without disrupting existing logic. Furthermore, black-box testing confirmed that all transitions between states operated correctly, with no issues such as dead ends or infinite loops. All branches executed as designed, achieving a 100% success rate.

Abstract

VirCle is a mobile-based social media application that was developed as a medium for communication and interaction between fellow users. Application user data is stored in the Firebase database, without any additional security mechanisms. Even though Firebase provides security services when data is transmitted as well as access management mechanisms, because Firebase is a back-end database service, where the accessing application and the data are on a separate layer, the stored VirCle user data can still be accessed, either by other external applications through programming interfaces, or users with specific roles in the system such as administrators. On the other hand, the existence of stored user data is very important and must always be kept confidential by VirCle application service developers and service managers. Therefore, this research aims to implement the Advanced Encryption Standard (AES) algorithm for encrypting VirCle application user data so that it has an additional layer of security. The encryption design uses the AES-128bit algorithm considering the speed of the encryption and decryption process which is relatively faster than other symmetric cryptographic algorithms. The AES implementation in this study uses the Kotlin language by utilizing the BouncyCastle 128-bit AES library and CBC operating mode and PKCS5 padding to assist the encryption and decryption process. The evaluation results show that the developed VirCle application can encrypt user data (plaintext) into coded data (ciphertext) which is then stored in the Firebase database, then successfully reads and decrypts the stored ciphertext data from the database for reuse. Evaluation of application performance from the speed aspect shows that the encryption and decryption process time for user data is quite fast with an average total time of 1.35 milliseconds for the encryption process, and 1.53 milliseconds for the decryption process. Apart from that, evaluating the Avalanche Effect (AE) from the results of the AES-128 bit encryption algorithm used, an average percentage of 50.36% was obtained, this shows that the level of data randomness is considered good.
