Abstract
This study aimed to assess the condition of the electrical wiring system at Cebu Technological University (CTU) during the fiscal year 2019-2020, serving as the basis for proposing a cost-effective electrical wiring system. The research was conducted specifically at CTU-Tuburan Campus (CTU-TC), utilizing the energy audit and descriptive research methods. To gather the necessary data for analysis, an inventory of electrical loads, electrical wirings, and circuit breakers was conducted. Electrical engineering computations were performed to calculate relevant data related to capacity, cost savings, and safety during the inventory process. The findings revealed that the existing electrical conductors and circuit breakers were inadequate to handle the total load of 483.285 kilowatts. Consequently, it was concluded that the current electrical wiring system at CTU-Tuburan is neither cost-effective nor safe, and it lacks the capacity to accommodate the existing electrical loads. Therefore, it is strongly recommended to implement a proposed electrical wiring system alongside a regular maintenance program. The proposed electrical wiring system aims to address the identified shortcomings by ensuring cost-effectiveness, safety, and improved capacity to handle the electrical loads. The regular maintenance program will help maintain the system’s functionality and longevity, ensuring its sustained effectiveness. Implementing these recommendations will result in an optimized electrical infrastructure for CTU-Tuburan, supporting the efficient and safe operation of its electrical systems.

Abstract
In 2020, COVID-19 forced several communities to isolate, and radio stations stepped up as leaders in communication and media during the pandemic, especially in rural communities where internet access is lacking. This study examines the vital role for disseminating information among urban and rural communities and improving services for clients who do not have access to the internet or television news updates. Specifically, this study analyses the demographics of the listeners of Bulawanong Tinubdan (BT) Radio 98.1 FM, a radio station of the Cebu Technological University-Tuburan campus and an affiliate of the Philippine Broadcasting Service (PBS), a government-owned network. It delves into the community perspective of the station’s programs, as BT Radio 98.1 FM endeavors to be an avenue for communication as well as teaching-learning platform during unexpected lifestyle changes like the COVID-19 pandemic. In addition, this study seeks to ascertain how listeners perceive the role of BT Radio programs in assisting the community in becoming more connected despite these constraints. The results show that the station captures the majority of the younger audiences in the community, while also highlighting how a campus-based FM radio station promotes community awareness across different age groups. This strengthens the position of the radio program as a learning environment that is widely accessible and that promotes information in the community.

Abstract
Cebu Technological University (CTU), with more than ten external and satellite campuses, has taken its outstanding share in alleviating the threats posed by mishandling solid wastes, including e-waste. Across the province of Cebu, the CTU administration has stretched out the responsible solid waste segregation and disposal campaign. It has taken steps toward helping the community become aware of sound solid waste management. However, no measures have been taken to properly handle unusable compact discs (i.e., CDs, DVDs), chargers, and other electrical and electronic wastes. Hence, there is a need to start seriously considering the proper forecasting and handling of these potentially harmful wastes by gathering enough evidence to support establishing an E-waste Management Center. This study aimed to design and test a system that will store Electrical and Electronic Equipment information in a database upon acquisition for proper tracking and ewaste volume forecasting. It provided an estimate for Recycling, Reusing, and Reducing opportunities. In developing the software, the researchers used the Agile Model, which consists of the following phases such asplanning, analysis, design, implementation, testing, deployment, tracking, and monitoring. The software application features included Supply Office Inventory, Maintenance Inventory, E-waste Inventory, Adding New Item to Inventory, Update Information, and Update Status from Inventory, Update Status from Maintenance, Update Status from E-waste, and Report Generation Module.Updating the status for Inventory and Maintenance means tagging the equipment as working, for repair, or salvage. Updating the equipment status from e-waste means tagging it for recycling, reuse, or salvage. The software application testing was done and resulted in the successful implementation of the needed features and functionalities.

Abstract
Portfolios are time-tested and teacher-trusted methods for assessing student learning. It is a tool for the students to keep their hard work. When they graduate they will be able to refer to their web-based portfolios with ease because they have been building them ever since entering college. The availability of graduates’ portfolios will become a ready marketplace for employers where they could find candidates who are a good fit for their needs based on validated reviews from faculty members who have witnessed the transformation of students from learners to qualified applicants. Employers and significant stakeholders will be able to provide comments and ratings to portfolios, which would provide valuable feedback to theuniversity to upgrade instruction and other practices relevant to the various programs. The objective of this study is to develop and test a web-based system that will provide an avenue for students to actively maintain a portfolio where they can have a ready e-portfolio that they can use and update according to their professional journey and thus would aid in the graduate tracer endeavor of the university, serve as an added functionality to the university website, thereby increasing the website traffic, ranking, and visibility, allow employers to find qualified and good fit candidates based on validated reviews from faculty members, and aid instructional improvement based on students’ employability and employers’ feedback. The software application was developed using the Agile Method. Testing was done using the test cases identified. The needed features were successfully implemented and tested. Based on the survey on measuring the system’s usability with the USE Questionnaire, respondents were satisfied with the features and ease of the system of use and they agreed that the system is useful for the university.

Abstract
Water stress in plants due to the effects of climate change resulted in reduced growth and yield of coffee in the tropics. Efficient use of water through the use of SMART irrigation systems available provides a promising solution to address such a problem. Thus, a study utilizing a combined climate- based and soil moisture SMART irrigation system has been conducted to assess its effects on the growth of Robusta coffee seedlings compared to practiced manual irrigation. The experimental design utilized a Complete Block Design (CBD) approach. Additionally, water consumption was measured to determine any significant differences. Over the course of the two-month experiment, 20 replications per treatment, it was observed that coffee seedlings subjected to the automated irrigation system (T1) exhibited significant improvements in both plant height and number of leaves, with growth rates of 72.56% and 65.29%, respectively, compared to manually irrigated plants (T0). Although the water savings achieved under the automated system were not statistically significant, there was an 18.95% reduction in water consumption. These findings highlight the potential benefits of automating irrigation systems using an IoT approach, specifically in terms of enhancing coffee seedling productivity. By utilizing real-time data from sensors, the SMART irrigation system effectively optimized water usage and resulted in improved growth and yield. This research underscores the importance of implementing such technological advancements to mitigate the adverse effects of climate change on coffee cultivation in tropical regions.

Abstract
This study aimed to evaluate the performance of the Biometric Attendance System (BAS) of Cebu Technological University-Tuburan Campus during the calendar year 2018 as basis for a proposed system improvement. This study used the quantitative research employing descriptive method that assessed the performance of the Biometric Attendance System as to timeliness, accuracy, graphical user-interface and system maintenance. The study was conducted at Cebu Technological University-Tuburan Campus, Tuburan, Cebu. There were 96 teaching staff and 48 non-teaching personnel who were chosen randomly to evaluate the performance of the Biometric Attendance System. Weighted mean was used to analyze and interpret the data. This study revealed the following findings: the BAS has six (6) features which are touch-screen user interface (TUI), system setup, administrators, finger registration, clock configuration and DTR pint menu. The overall performance of the biometric system was very satisfactory in terms of timeliness, accuracy, and graphical-user interface. Hence, biometric system has always ensured employees’ timeliness, provided accurate employee attendance record, and accommodated well the employees in their daily use of the biometric. Thus, it utilized a corrective form of maintenance only for emergency cases or is done after the problem occurred such as system reboot for downtime related issues and database backup. Lastly, “employees forget to log in/out” is found out to be the number one (1) problem in the daily use of biometric system. Formulation of a proposed system improvement on the lapses of the performance of the current biometric attendance system is the output of this study.

Abstract
Eggplant is one of the high-value vegetable crops in the country that has been studied for growth and yield improvement due to its nutritional and medicinal benefits to the consumer. Thus, a study was conducted utilizing the Sargassum polycystum seaweed extract as foliar fertilizer for eggplants to assess its growth and yield responses. The study was arranged in a randomized complete block design. Treatments were control (no foliar application of seaweed extract), recommended commercial fertilizer (10 g of 14-14-14), 0.5% v/v, 1.0% v/v, and 1.5% v/v seaweed extract in water. Results show improvement in eggplant growth and yield parameters applied with seaweed extract (P < 0.05). Application of 1.0% v/v seaweed extract resulted in the highest plant height (44.00 ± 7.28 cm) and root length (21.61 ± 4.83 cm) for eggplant, comparable to all plants applied with commercial fertilizer (39.06 ± 10.32 cm, 20.28 ± 3.64 cm), 0.5% v/v (42.33 ± 11.11 cm, 20.78 ± 3.84 cm) and 1.5% v/v (42.06 ± 10.56 cm, 20.11 ± 4.50 cm) of seaweed extract, respectively. A similar result was observed for leaf number and leaf width. Moreover, 1.0% v/v of seaweed extract application got the highest number of fruits per plant (3.00 ± 0.49), fruit length (16.00 ± 0.77 cm), fruit circumference (10.92 ± 0.67 cm), and fruit weight (97.22 ± 37.27 g). Hence, the foliar application of 1.0% v/v seaweed extract is recommended for more profitable and sustainable eggplant production.

Abstract
Andrographis paniculata (Burm.F.) Wall ex. Nees is an important medicinal plant in ASEAN countries that drives a high demand in the worldwide medicinal plant trade due to its andrographolide content. To find out optimum lighting and culture conditions in vitro, seed cultures were grown on photoautotrophic (sucrose- free) and photomixotrophic (3% sucrose) media. Blue and red monochromatic LED lights were used at an irradiance intensity of 40 µmol m-2 s-1 for 20 days as an energy source. Photosynthetic responses were measured in terms of chlorophyll content and net photosynthetic rate. Morphological responses were measured in terms of leaf and internode count, shoot length, number of roots, root length, fresh weight, and dry weight. Results were analyzed using SPSS 11.5 software. Gas chromatography results show that net photosynthetic rate was higher under blue light while red light resulted in taller plants. Root count and root length were higher under red light by 11% and 9.7% respectively. Sucrose reduced the net photosynthetic rate under both light spectra. Furthermore, plants under photoautotrophic conditions grew taller shoots and higher fresh weight. However, photomixotrophic blue light plants showed the highest dry matter content. Spectrum- wise, red light plants have a higher dry weight but when sucrose was involved in the growing medium, blue light plants outweighed it by as much as 7.91%. This suggested hyperhydric tissues in other cultures. Photosynthesis is constrained often by the low concentration of CO2 in photomixotrophic cultures as sucrose has been observed to act as an osmotic agent in in vitro culture systems.

Abstract
Distinct to today’s society is rapid change, exemplified in the swift demands that confront professionals and working life. As this ripple to and challenges the educational set up to mold competent individuals, changes occur as the education paradigm shifts. One such change is Constructivism which asserts learning to be an active process where learners actively build on their experiences and knowledge. Students’ perceptions of the classroom learning environment are significant and should be of interest to teachers. The study employed a Constructivist Learning Environment Survey which was responded by163 first-year college students. It was intended to assess how students perceive their Science class as taught using the Constructivist approach. It utilized the Statistical Package for the Social Sciences software to analyze data. Findings revealed that students perceived their Science class as “often” taught using Constructivism. Likewise, of the five Constructivist dimensions identified and utilized for this study, four dimensions were regarded as “often” perceived by the students in their science class, the highest often perceived dimension being Student Negotiation. Contrastingly, the only dimension perceived “seldom” by the students and scored the lowest is Shared Control. Thus, it resulted that there is no relationship between the teacher’s teaching experience and the teacher’s use of constructivist practices.

Abstract
Research Aims: The present study aims to document perceptions and identify the challenges on the participation and role of technology business incubators (TBIs) of select academic institutions in Visayas, Philippines. Design/methodology/approach: It is quantitative-qualitative research, which utilized survey questionnaires and focus group discussion of twenty-five (25) key informants (KIs) from nine higher education institutions (HEIs) in the Visayas. KIs include key officials and faculty who handled research, technology transfer, business incubation, intellectual property, and/or technology licensing functions in their respective HEIs. Research Findings: All KIs were from state universities or colleges, and most KIs were female (64%), married (60%), and holders of a doctorate degree (72%). Results showed that most KIs had good knowledge of TBI operations and intellectual property rights, but acknowledged the need for developing capacities and facilities for the TBI operations. Theoretical Contribution/Originality: This study identified key challenges and concerns of the HEIs that can affect the implementation and operations of the TBI program in the Philippines which include the training needs of the faculty, lack of manpower and budget, and the sustainability of the facility/operation. The HEIs also need support from government agencies and non-government organizations. Managerial Implication in the South East Asian context: TBI can help in the improvement of the country’s innovation index, technopreneurship, and value creation. Philippine HEIs should consider the cost and sustainability of setting up TBIs as well as how they benchmark their activities against other Southeast Asian countries. Research limitation & implications: Although the sample appears to be limited, data was collected from key HEI managers and decision-makers. Therefore, this study can still provide insights for current and prospective TBIs to help address common concerns and formulate policies and strategies for the operations and sustainability of the program in their respective HEIs.

Abstract
This study examined the stress encountered and stress-coping skill used by the school principals, enabling the development of an improvement program for workrelated outcomes in educational contexts. An adapted survey questionnaire was distributed to school principals and teachers-in-charge of public schools in the Asturias district of the Cebu division in the Philippines. The first part of the survey questionnaire collected personal and professional details from school principals, while the second assessed their performance. Five categories of stressors were identified: administrative responsibilities, administrative constraints, interpersonal relationships, intrapersonal conflicts, and employers’ expectations. The respondents’ stress-coping strategies were then analyzed for their suitability and effectiveness in stress management. The data were analyzed using frequency, simple percentages, weighted means, and correlation coefficients, which revealed the extent of the stress they encountered from each of the five categories of stressors as well as the stresscoping strategies preferred by the school principal and observed by other teachers. Based on the findings, it is recommended that an improvement program be developed for work-related outcomes in educational contexts, focusing on school principals and stress management, which may be referred to as the Dynamic Administrative Performance Network.

Abstract
Waste is an unavoidable by product of human activities. Economic development, urbanization and improving living standards in cities have led to an increase in the quantity and complexity of generated wastes. There is a growing need to evaluate whether lessons learned in the classroom are practiced at home. In connection, ecological waste management should be integrated in educational instruction. With that, the researcher determined the level of ecological waste management practices among Second Year Bachelor of Elementary Education(BSED) students of the Cebu Technological University – Tuburan Campus during Summer class of Academic Year 2016 – 2017, and its relationship with their performance in Ecology subject. To achieve the purpose of this investigation, the researcher utilized a quantitative, non-experimental approach specifically the descriptive – correlational survey method with adapted questionnaire; the weighted mean was utilized to assess the ecological solid waste management while Chi Square Test was used to test the association between the performance of the respondents and their practices on solid waste management. Findings revealed that the respondents “sometimes” performed what they have learned. Results showed that there is a highly significant association between the performance of students and their ecological solid waste management practices. Ten (10) least performed practices were identified and became the basis for creating IEC materials. The study concluded that the higher the students’ grades in the Ecology subject, the more likely they will practice what they have learned. Information Education Campaign materials are, therefore recommended to further improve their level of practices.
