Because of rapid urbanization and population increase, Clean water sources have become limited. There are concerns for all residents, businesses, and institutions in Nabua, Camarines Sur. Furthermore, this situation is intensely felt in learning institutions like the Camarines Sur Polytechnic colleges because not only will the water supply coming from the Local water district decrease, but the water demand will also increase due to an increase in student population annually. A multi-water source approach can be utilized to mitigate this water shortage on the campus. Several water sources, such as rain and groundwater, still need to be fully utilized. Considering these multisource water systems, some challenges facing where Automation should be best applied include Water Source control, Water distribution system Operation management, and Cost Reduction. However, before adopting these Multisource-water supply automated control systems, it is crucial to assess their effectiveness to maximize the benefits of their performance, and various elements should be considered. Integrating Automation is highly effective in controlling pressure, which means that within the distribution pump capacity, the automated system can control the pressure within the specified control limit at any water flow rate without affecting the adequacy of the end user's demand. A prototype simulating the function and features of multi-water source automation is built to show how the control system will perform in different conditions depending on the available water source and end-user water demand.</p> Christopher Gutierrez Copyright (c) 2025 Journal of Engineering and Emerging Technologies https://creativecommons.org/licenses/by-nc-nd/4.0 2024-12-30 2024-12-30 3 1 1 15 10.52631/jeet.v3i1.287 https://journals.cspc.edu.ph/index.php/jeet/article/view/281 <p>Concrete has been long used in the field of construction. Coarse aggregate is a major component of concrete, and its size can vary. Abrasion resistance is one of its properties, which depending on the source and size of the aggregate, can impact concrete strength. Throughout the use of concrete, only abrasion resistance of concrete is correlated to the strength of concrete. Thus, this study aims to create a mathematical relation between the abrasion resistance of coarse aggregates and the compressive strength of concrete, considering two nominal maximum sizes from different quarries in Camarines Norte. Experimental methods such as the Los Angeles Abrasion Test, Paired t-test Analysis, The One-Way Analysis of Variance, and Bivariate Correlation Analysis were employed to investigate the substantial correlation between the abrasion resistance of coarse aggregate and the compressive strength from three different quarries, with reference to ASTM and ACI standards governing concrete. The result shows that among the three quarries, only Calabasa attained the standard abrasion resistance of coarse aggregate of 50%. Hence, only in One-Way Analysis of Variance resulted a significant relationship but not in Paired t-test Analysis and Bivariate Correlation.</p> Kurt Juden Pardo Frances Angelique Cereno Vincent Jerome Cereno Micco Limuel Malaluan Neil Villafuerte Copyright (c) 2025 Journal of Engineering and Emerging Technologies https://creativecommons.org/licenses/by-nc-nd/4.0 2024-12-30 2024-12-30 3 1 16 26 10.52631/jeet.v3i1.281
