Phytochemical screening and antibacterial efficacy of Musa acuminata x balbisiana (saba banana) peel crude ethanolic extract against meat spoilage-causing bacteria
Full text linkAbstract onlyMusa acuminata x balbisiana (saba banana) is a perennial herbaceous plant that has high phytochemical content in its different plant parts. However, 15-60% of its fruit remains underutilized. Banana fruit peels which is equivalent to up to 40% of the total weight of fresh banana comprise a significant quantity of wastes produced from saba banana processing. This study evaluated the antibacterial activity of the crude extract of saba banana peels against meat-spoilage-causing bacteria, Escherichia coli and Staphylococcus aureus. Disk diffusion assays showed the inner peel extract had zones of inhibition (ZOI) ranging from 22-38 mm against S. aureus and 30-36 mm against E. coli, comparable to the whole peel extract (34-37 mm against S. aureus and 30-34 mm against E. coli). Amoxicillin was used as a positive control, showing zones of 39-56 mm. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extract were determined using concentrations ranging from 37.5 to 600 ppm. The ethanolic crude extract of saba banana inner peel had a MIC of 75 ppm and MBC of greater than 600 ppm. The promising antibacterial activity shown by the treatment may be attributed to the presence of alkaloids, tannins, saponins, proteins, phenols, flavonoids, glycosides, carbohydrates, and terpenoids found using qualitative phytochemical analysis. Thus, the ethanolic crude extracts of saba banana inner peels may be used as an antibacterial agent against meat-spoilage-causing bacteria. This study has identified an important potential antimicrobial agent obtained from what is generally considered waste from the food production sector. Considering its strong inhibition activity against common spoilage-causing bacteria, E. coli and S. aureus, saba banana peel extract offers a new avenue for further research as it may have potential applications in food safety, handling and preservation of meat products, and improving human health.Include bibliographical referencesBachelor of Science in Biolog

Optimization of protection coordination in the power system (OPCIPS) of Central Philippine University
Full text linkAbstract onlyCentral Philippine University (CPU) is a well-established school that has expanded over the years, resulting in increased demand for a reliable and efficient power system. However, its current protection coordination scheme is outdated and not adequate for the latest energy needs. The goal of the study is to build up an optimized protection coordination system for CPU power supply to improve its reliability. To initiate the study, the team conducted an extensive assessment of the current electrical system, reviewing historical fault records and component-level contributions to system failure. On the other hand, CPU still uses old electrical drawings which resulted in errors in coordination of fuse protection. The researchers then used the ETAP simulation software to examine the fault performance of the system. The findings were vast majority of coordination problems were located at Feeder 2 (65A, pole P03), RMA (100A, pole P15FDR2), JHS (40A, pole P26FDR2-T9), and near Mary Thomas building (50A, pole P32FDR2). In addition, a few locations were noted as having high fault potential, such as areas close to the Senior High parking area, LHB and Mary Thomas, Theology, Elementary, Engineering, LDT, and CHM buildings. Based on the analysis of the results from the fault identification survey and ETAP tests, the researchers proposed modifications were; change the fuse size of FDR2 UGym Iso 65A from 65A to 100A, FDR2 RMA Iso 100A from 100A to 80A, FDR2 Iso 40A located at pole P26FDR2-T9 from 40A to 50A, FDR2 MT Iso 50A located at pole P32FDR2 from 50A to 40A, installation of isolation fuse at pole P5FDR1 T-2 with rating of 30A, and installation of isolation fuse at pole P18FDR2 with rating of 65A. These modifications were already tested in ETAP to make sure the desired outcome are met.Includes bibliographical referencesBachelor of Science in Electrical Engineerin
Prototype development of a fogging evaporative cooler for indoor thermal comfort in the CPU Engineering student council office
Full text linkAbstract onlyThis research tackles the growing issue of indoor thermal discomfort in tropical regions by designing, assembling, and evaluating a fogging evaporative cooler prototype for the Engineering Student Council Office at Central Philippine University in Iloilo City. Due to increasing global temperatures and elevated humidity in the Philippines, traditional air conditioning systems consume a significant amount of energy and are expensive. The evaporative cooler with fogging features a 50-liter water reservoir, a 12-head ultrasonic mist generator (8.4 kg/hr fog production), a chassis fan, and a stand fan, designed as an energy-saving option. The cooling load for the office was determined to be 4405.18 W (5.91 HP) utilizing psychrometric analysis and evaluations of thermal load.
Testing in both open (ventilated) and closed (sealed) setups during 8-hour operation periods showed temperature decreases of 0.6–1.1°C (for open) and 1.2–3.0°C (for closed) when compared to outdoor maximums of 31.1°C. While the desired conditions of 24°C and 50% relative humidity (RH) were not met, indoor temperatures settled between 27–30.9°C. Humidity increased to 68–73% RH (open) and 84–90% RH (closed), underscoring the essential role of ventilation in managing moisture. The system used 0.8 L/h of water (6.4 L overall) and functioned at ₱67.80/day (0.565 kW total power).
Despite its affordability and low energy consumption, the research does not recommend the prototype for practical application. Rather, it serves as an exploratory study that reveals the performance limitations of fog-based evaporative cooling in humid indoor conditions. The study provides a foundation for further investigation and refinement of low-cost cooling technologies suitable for tropical climates.Includes bibliographical referencesBachelor of Science in Mechanical Engineerin

Field testing was conducted over three days for each season, following the PNS/BAFS 325. Data were measured and calculated to determine the efficiency of the project. Results indicate that during the wet season, Pump 1 exhibited an average discharge of 108.01 m3/hr with a system efficiency of11.41% and 75.94% pump set efficiency, while Pump 2 had a lower discharge of 97.15 m3/hr with a system efficiency of 7.51% and pump set efficiency of 53.87%. On the other hand, in dry season, Pump 1 exhibited an average discharge of 98.08 m3/hr with a system efficiency of 3.99% and 65.40% pump set efficiency, while Pump 2 had a lower discharge of 87.18 m3/hr with a system efficiency of 3.69% and pump set efficiency of 49.33%. Overall, the BF-SPIS led to a 13.63% increase in rice yield, highlighting its positive impact on agricultural productivity. It is recommended to improve the conveyance and resupply project for the water reservoir, divert the excess solar energy to the grid by having hybridization of the system for it to function at night, increase the capacity of the water reservoir, and improve conveyance for water delivery in the field, reinspection and modification of the solar panel set up and lastly conducting a cost-benefit analysis for the BF-SPIS economic viability and overall benefits.Include bibliographical referencesBachelor of Science in Agricultural and Biosystems Engineerin
The relationship between personality traits and social media use of college students in a private higher education institution
Full text linkFull text availableThe study sought to investigate the correlational relationship between personality traits and social media use, utilizing a sample population of 231 college students across all years studying in a private higher education institution. The study uses the “Big Five” or “Five-Factor Theory” as a theoretical basis. The respondents were chosen through stratified random sampling and the data gathered included the respondents’ prevalent trait according to the Big Five Personality Traits, their social networking site most used, and their average daily time spent on social media. The researchers hypothesized no significant relationship between personality traits and social media use. Analyzing the relationship between respondents’ Personality Traits and Average Daily Time Spent on Social Media using the Chi-square Likelihood Ratio yielded p=0.052, thus rejecting the null hypothesis and indicating a significant relationship between the two variables, opposing the original hypothesis. Similarly, association of the Respondents' Personality Traits and Social Networking Site Used resulted in a value of 0.039, likewise suggesting a significant relationship between the two variables and contradicting the previous hypothesis. Ultimately, the researchers found that there is a positive correlation between the Big Five Personality Traits and the Average Daily Time Spent on Social Media, as well as Personality Traits and Social Networking Site Used.Includes bibliographical referencesBachelor of Science in Psycholog
Influence of specimen size on the small strain dynamic properties and strength of compacted Bentonil-WRK bentonite for nuclear waste repository
No full textJournal articleThis study examines the small-strain dynamic properties and strength of highly compacted Bentonil-WRK bentonite, a candidate buffer material for engineered barrier system (EBS) in South Korea. Free-free resonant column (FFRC) and unconfined compressive tests (UCT) were performed on specimens with varying diameter sizes (Ø), dry density (ρd), and degree of saturation (Sr). FFRC determined shear, unconstrained and constrained compressive wave velocities (Vs, Vc, and Vp, respectively), small-strain moduli, material damping in shear (Dsmin) and longitudinal (Ducmin). The influence of increasing Ø, ρd, and Sr were investigated by utilizing seismic waves to (1) determine the dynamic stiffness, (2) characterize material damping, (3) permit direct calculation of dynamic Poisson's ratio (v), and (4) develop moduli and strength correlations. An inverse size effect was observed, wherein increasing Ø reduced velocities, moduli, damping, v, and strength. Conversely, increasing ρd enhanced mechanical properties, with maximum values at around 70 % Sr. Plasticity index and mineral constituents contributed to the observed nonlinearity in Dsmin and Ducmin. Although Ø and Sr partially contributed, mechanical correlations were primarily influenced by ρd under unconfined conditions. Hence, the proposed wave-based equations enable practical assessment of bentonite buffer blocks after production and prior to installation in nuclear waste repositories

Full text linkFull text availableThis study explores the relationship between the use of self-deprecating humor in social media and its relationship with academic stress among BS Psychology students at a private higher education institution. Utilizing a quantitative research design and stratified random sampling, the survey included 237 participants to assess demographics, humor usage, academic stress levels, and the impact of social media platforms and exposure. Results showed moderate levels of self-deprecating humor utilized across genders and platforms, with significant differences linked only to the duration of social media use. Academic stress levels were also found to be moderate among participants. Lastly, a weak but significant positive correlation was identified between the use of self-deprecating humor and academic stress, indicating that greater use of self-deprecating humor may correlate with increased academic stress levels.Includes bibliographical referencesBachelor of Science in Psycholog
Health literacy, help-seeking behaviors, and resilience among student nurses in a selected private college of nursing
Full text linkAbstract onlyStudent nurses are vulnerable to psychological distress such as anxiety, depression, and stress. While they may experience less distress than frontline healthcare workers, they still face emotional challenges. This study aimed to determine the levels of health literacy and help-seeking behavior among student nurses, and how these factors contribute to enhancing their resilience. A descriptive-correlational design was used. Respondents were randomly selected student nurses from a private college of nursing in Antique, Philippines for the academic year 2024–2025. Data were collected through survey questionnaires after ethical clearance was granted by the CPU-RERB. Descriptive statistics summarized the data, and Spearman’s Rho determined the relationships between variables. Results showed that health literacy and help-seeking behavior were at moderate levels, while resilience was high. A strong positive correlation was found between health literacy and help-seeking behavior (ρ = 0.787, p = 0.000), and a moderate positive correlation between help-seeking behavior and resilience (ρ = 0.466, p = 0.007). These findings suggested that student nurses with higher health literacy are more likely to seek help, and that increased help-seeking behavior significantly contributes to stronger resilience. Promoting health literacy and encouraging proactive help-seeking can enhance student nurses’ ability to cope with psychological challenges.Includes bibliographical referencesMaster of Arts in Nursin
Support system, knowledge, and compliance with tuberculosis (TB) treatment among older persons in a selected Rural Health Unit (RHU) in Iloilo
No full textAbstract onlyThe researchers aimed to understand the support system, knowledge, and compliance with tuberculosis (TB) treatment among older persons in a selected Rural Health Unit(RHU) in the province of Iloilo. With the initial population of 212 individuals, the researchers were able to select 139 older persons with random sampling and utilizing a descriptive-correlational research design. The researcher-made questionnaire has 29items, with 8 items for the level of support system, 12 for knowledge, and 9 for compliance. A small-scale group was given a pilot test for reliability. Expert validators in the fields of public health and nursing have tested the research instrument's validity. In order to minimize potential recall bias, the collection of data was done over one month. With the assistance of appropriate statistical software, the data collected from the respondents were interpreted in a descriptive and inferential statistical analysis where the interpretations generally imply that the older persons diagnosed with Tuberculosis(TB) have a high level of support system, denoting that strong social networks a represent. The respondents reported a moderate level of knowledge regarding TB, indicating gaps in health education efforts. However, the majority of respondents exhibited a low level of compliance with treatment, suggesting potential barriers to adherence despite knowledge and support. There is a significant relationship between support system and compliance, indicating that individuals with stronger support networks are more likely to comply with treatment. There is also a significant relationship between knowledge and compliance, suggesting that better understanding of TB and its treatment is associated with improved adherence.Include bibliographical referencesBachelor of Science in Nursin
