PerSafS Marketing Corporation (PMC) is a micro enterprise that sells safety and health equipment such as gloves and masks. A database and a web-based application to interact with it was developed as business data grows. The application enables its employees to access and edit their data. It also has features such as printing out invoices that aid in the business’ workflow. The system received an average usability score of 78.043.

Time efficiency is crucial for users to achieve their needs using a platform. Elbishare is a web application tailored for students at the University of the Philippines Los Ba ˜nos (UPLB) for sharing, borrowing, and donating items. This study outlined the development and evaluation of Elbishare, which was designed to enhance the efficiency of sharing and discovering posts within the UPLB community. Using surveys and task analyses, Elbishare’s performance was compared to Facebook Groups, a widely used platform for similar and other purposes. The results demonstrated that Elbishare significantly reduced the time needed to find items and provided a favorable user experience, resulting in an increased time efficiency of 80.89% in searching for shared items, 89.67% for borrowed items, and 81.30% for donated items. With a System Usability Scale (SUS) score of 88.35 from the responses of the 20 UPLB students, the system was classified as having excellent usability, characterized by ease of use, efficiency, and user satisfaction

It is commonly practiced to monitor water param- eters in the aquaculture setting in order to maximize production sales and reduce post-harvest loss. However, traditional methods often require one’s presence in the body of water as well as the usage of different instruments in gathering data. In line with this, the automation of this process and remote monitoring becomes essential in order to achieve this process efficiently. This study developed an Arduino-based component, the ESP32 Microcontroller, connected to several sensors that transmits the values of water parameters to a mobile application, which not only alerts the user when a parameter exceeds the threshold but also includes an annotation feature for contextualizing and interpreting dynamic changes in the aquatic environment.

The Glory of Zion Children’s Clinic is a pediatric clinic that has been treating patients for more than 30 years. In this period, the clinic has accumulated hundreds of records making maintenance a difficult task for its staff. In this study, a web application was created that aims to create a database for the patient records and inventory for other items used around the clinic such as vaccines and medicines. The application was tested by 5 respondents, which were all the clinic’s staff. The application received a System Usability Scale (SUS) Score of 92.5, an acceptable and good score. The application also received feedback to improve the development of the application.

With the vast amounts of data being moved and communicated throughout the internet and different computer networks, a large portion of these carry sensitive and confidential information that should not be available for the public, thus the growing importance of information security. In this study, an audio steganography tool that is aimed to protect and hide sensitive information that can be inconspicuously transmitted through digital audio files is developed. It uses the Twofish encryption algorithm for the message encryption and decryption, the Spread Spectrum algorithm for the message embedding method, and the logistic chaos map for the prng of the chip-code generator. The tool’s encoding process is evaluated to have an average PSNR of 46 dB which is considerably good and preserves signal quality. It is also reliable in retrieving the message with an average BER of 0% or a retrieval accuracy rate of 100%. When tested against existing steganography tools, its output audio could not be decoded by these tools which makes it well protected against these existing methods. Lastly with an average SUS score of 91.25, the tool is considered very good in terms of effectiveness, efficiency, and user satisfaction.
