Abstract
The widespread use of Liquefied Petroleum Gas (LPG) in households and industries presents a significant risk due to its highly flammable nature, making early detection of leaks for preventing accidents. Traditional LPG detection methods often rely on manual monitoring, which may not provide timely alerts or automatic responses to prevent accidents. The Internet of Things (IoT) refers to a network of physical objects, or “things,” embedded with sensors, software, and other technologies that enable them to connect and exchange data with other devices and systems over the internet. The advantage of the Internet of Things (IoT) offers new opportunities to safety systems through real-time monitoring and remote alerts. By integrating IoT technology with LPG leak detection, it is possible to create a responsive and reliable safety system. This device focuses on the development of an IoT-based LPG tank leakage detection system with alarm and auto-off system, designed to detect leaks, sound an alarm, and automatically shut off the gas supply or even remotely turn off the valve through an android-based application to prevent accidents. The system uses IoT for real-time data transmission and remote monitoring, allowing users to receive instant notifications and take immediate action, even when away from the premises. The system uses gas sensors to continuously monitor LPG levels, triggering an immediate response in the event of a leak. Integrated with IoT technology, the system provides real-time alerts to users via android-based application, ensuring prompt action.

Abstract
In the Philippines, a country characterized by mountainous landscapes and frequent intense weather events such as typhoons and monsoons, the issue of slope failures has become increasingly pressing. This study investigated the impact of soil cohesion on slope stability using numerical modeling. The SLOPE/W software and Morgenstern-Price method were employed to simulate various slope scenarios with varying cohesion values. Results indicated a strong positive correlation between cohesion and factor of safety (FOS), highlighting the critical role of cohesion in slope stability. Analysis of Variance confirmed the statistical significance of cohesion variations on Factor of Safety. The findings underscore the importance of incorporating cohesion in geotechnical design and slope management, especially in regions like the Philippines with diverse topography. Future research should explore the combined effects of other soil properties and validate numerical results through field testing. By considering cohesion, engineers can optimize slope safety and minimize the risks of slope failures.

Abstract
A sustainable electronics engineering program effectively prepares graduates to tackle the changing technological, environmental, and societal challenges. In this context, this study examines the relationship between Outcome-Based Education (OBE), quality assurance mechanisms, and student performance in the Electronics Engineering Licensure Examination with the goal of enhancing the development of the program and making it more sustainable. To do this, the paper analyzed a five-year dataset to examine key factors such as accreditation by the Philippine Technological Council (PTC), international rankings (QS and THE), and recognition as Centers of Excellence (COE) or Centers of Development (COD) by the Commission on Higher Education (CHED). Regression modeling of the data gathered revealed that the linear interaction model most effectively predicts student performance, with an R-squared value of 0.85, highlighting the emphasis on OBE and quality assurance to improve academic results. The study concluded that emphasizing interactions among program attributes can guide curriculum revisions to enhance student success and ultimately, its sustainability. It suggested that future studies integrate machine learning (ML) techniques to improve the predictive capabilities of model to enhance quality assurance measures. This may be done by utilizing ML methodologies from related fields such as human detection systems and ECG analysis and apply it to educational research. Such an implementation can enhance data-driven decision-making processes, thereby improving the quality of education and student performance in the Electronics Engineering Licensure Examination and ultimately, making the program more sustainable.

Abstract
Rice is one of the essential food crops consumed by every Filipino due to it being a good source of energy and protein. However, well-milled rice mostly encounters rice weevil (Sitophilus oryzae) invasion during their prolonged storage, causing severe damage to rice grains. Several solutions have been proposed to address the problem, but these solutions may harm the consumers and oftentimes, lengthy, and tedious. This study developed an automated rice sieving device (ARSD) with a heat-controlled system for the reduction of Sitophilus oryzae, programmed in Arduino IDE (C++) for automation and genetic algorithm using Python for optimum angle of inclination for sieving. Results showed that the device can effectively and efficiently separate rice weevils and rice grains at sieving inclination of 15 degrees and can eliminate rice weevils within 1 minute at constant temperature of 54°C, exhibiting a 100% mortality rate. The optimum angle of inclination at 15.7° is obtained from the genetic algorithm using Python. Furthermore, at optimum angle of inclination and 1 minute heating time, the device is reliable in sieving 1 to 3 kilograms in four rice varieties namely Malagkit, Denorado, Angelica and Sinandomeng with an average percentage value of 97.9167, 96.1458 and 92.6042 with respect to their respective rice weights (1 kg, 2 kg, and 3kg), proving that ARSD is a potential solution in addressing rice weevil problems.

Abstract
This study centers on the essential role played by Speech-Language Pathologists (SLPs) in the diagnosis and treatment of speech and language disorders within the Philippines. It underscores the significant difficulties resulting from the limited availability and effectiveness of Augmentative and Alternative Communication (AAC) tools, particularly in the context of the Filipino language. These limitations impede the progress of Filipino children struggling with speech delay disorders. The study aims to develop AAC software integrated with an intelligent tutoring system in Filipino. This innovative approach incorporates Filipino AAC tools such as AAC boards, assessments, client management, and identification of rapidguessing behavior on AAC assessments on different difficulty levels using a decision tree algorithm, providing a structured and personalized therapy approach. The software was evaluated using FURPS with a total of 50 participants, whom are the 30 or 60 % speech-language pathologists, 8 or 16 % Information Technology and Computer Science (IT/CS) professionals, 2 or 4 % CS Professors, and 10 or 20 % Parents/Guardians. The computed Cronbach's alpha (α
) was 0.95 which indicates the FURPS instrument has excellent internal consistency. The grand mean of the software evaluation was rated at 4.63 which highlights the generally positive evaluation of the system. Precision, recall and F1-score assess the model's performance in binary classification. For the class labeled “0,” the model achieved a precision of 0.99, a recall of 1, and an F1 score of 0.99. This indicates that the model has high accuracy in predicting instances belonging to class “0.” For the class labeled “1,” the model achieved a precision of 0.95, a recall of 0.92, and an F1-score of 0.93, indicating slightly lower performance than class “0.” The findings of this study and the developed software have significant implications in the field of AAC. Additionally, this study's contribution serves as a foundation for future advancements in AAC-related technologies, driving innovation and improvement in the field.

Abstract
The use of Cocos nucifera (coconut shell) ash as a supplementary cementitious material has shown potential in enhancing the compressive strength of concrete. However, the optimal calcination temperature and duration for producing effective ash remain uncertain. This study employs a Central Composite Design (CCD) to investigate the effect of calcination on concrete strength. Nine combinations of temperatures 550°. to 800°C) and durations (1 to 3 hours) were tested, producing 13 samples, which were cured for 28 days before compressive strength testing. X-ray Fluorescence (XRF) analysis identified 15 elements, with iron significantly influencing strength. The highest compressive strength (24.9 MPa) was achieved at 675°C for 2 hours, where iron content reached 16.63 %. A full quadratic regression model was developed, with an R2 of 79.47 %, and backward elimination refined the model to a predicted R2 of 67.32 %. Sensitivity analysis revealed temperature as the most significant factor, with a sensitivity value of 14.53 compared to 1.48 for duration. Optimization indicated the ideal calcination temperature to be 672.81° C. This study supports sustainable development goals by advancing innovative materials for infrastructure and by promoting the use of agricultural waste, reducing the environmental footprint of concrete production.

Abstract
Navigating to find attractions can be challenging for tourists due to the lack of navigation websites that pinpoint any tourist attractions within Metro Manila. The lack of navigation websites may lead to fewer tourists visiting the place and hinder tourism in the area. To resolve this issue, the researchers developed ‘SpotN’Go: An interactive web-based platform promoting the best places to visit in the city of Manila.' This website promotes various attractions including historical sites, old churches, and parks where visitors can enjoy their visit. By blending educational content with an entertaining format, the platform helps users understand the history and appreciate the beauty of the places they visit. The study uses an Input-Process-Output (IPO) design. Users (input) provide information and feedback throughout development. This information is used to improve the web platform (process), which showcases Manila's attractions. The enhanced platform is then beta tested (output) to identify and fix errors before the final launch. A survey assessed the system's quality using the FURPS model (Functionality, Usability, Reliability, Performance, Supportability). Public users (tourists) rated it ‘Strongly Agree’ overall, while IT administrators rated it ‘Agree’ across all aspects (average score: 4.06). This suggests the system meets its goals for both user groups. The study concludes that SpotN'Go successfully achieved its goals by creating a web platform that showcases Manila attractions through information, videos, photos, and maps. The researchers recommend further development to promote various tourist spots that will have a positive impact on Philippine tourism and tourist attractions.

Abstract
Research on affinity spaces in the Philippines is lacking, namely the subjects-the online communities of vtubers, furries, and fanfiction. As such, the research objective includes to gain a better understanding of these affinity spaces, and implement them to the research's audience through informative explainer videos coupled with a narrative. There is also a digital campaign, and an animated music-video to act as a climax to the aforementioned narrative. The research is conducted in the perceived context of having these affinity spaces largely related to the nature of the multimedia space and contemporary world in general, as well as being related to the study of online community behaviors. Once project context and related literature are gathered, the output commences in production, then a formative evaluation is conducted, followed by a summative evaluation after sampling project demonstrations. The methodology used for the data gathering employs a mixed method approach, with a qualitative approach used mainly for interviews with experts on the fields, and quantitative on surveying the respondents about the project. Purposive nonprobability sampling will be used when dealing with quantitative data, purposive sampling for gathering substantial amounts of information from point persons, and Slovin's formula for unbiased samples respectively. The population sample will be gathered from third year students currently enrolled in the Multimedia Arts from FEU Institute of Technology, while clustering ages 16-25 in gen z. A majority of the data gathered from the evaluations yields satisfactory categories in surveys from summative testing, compared to a lower score on formative, which entails a success when deducing how audiences would learn more about these affinity spaces. Thus far, the research adds available academic information regarding these topics in the Philippine context, to which any interested party may source from.
