ABSTRACT


This study aims to develop an E-learning system for the Graduate Program to address teaching-learning issues. This system is a significant tool in helping instructors, students and department heads as they can manage and monitor classes online with facility, effectiveness, and efficiency. The system for the Graduate Program includes course management, classroom management, learning management, online assessment management, monitoring message board for communication, course feedback for instructors, and virtual classroom for discussion. RAD (Rapid Application Development) was applied in developing this system. This model is a team-based technique that focuses on fast information system development for the construction of prototypes which allow users to examine a working model as early as possible, to determine if it meets their needs, and to suggest necessary changes. The model includes phases of planning, analysis, prototype cycle, design, implementation and deployment. After the system was done, a questionnaire was given to the respondents. The questionnaires were taken from ISO standard questionnaires for evaluating systems functionality, reliability, usability, efficiency, maintainability, and portability. After the evaluation was done, it was found out that all aspects of the system were rated above the average which indicates that the system complies with all the necessary functionality and features of an E-Learning System. Thus, the system can be implemented in the Graduate Program of Central Philippine University.

ABSTRACT


This paper is an assessment of the outcome of research collaboration between 4th year De La Salle University (DLSU) Civil Engineering students major in Transportation Engineering and 4th year Civil Engineering students of Central Philippine University (CPU), Iloilo City. Specifically, it aims to identify issues and concerns in terms of time, communication, computation knowledge and tools, and logistics/resources during the research collaboration process, gather feedback from those involved and recommend improvements. Three undergraduate thesis groups from DLSU-Manila composed of eleven (11) students and four (4) groups from CPU-Iloilo City composed of twelve (12) students were asked to rate the research collaboration between the institutions as the students worked together under the guidance of their thesis advisers from both universities. Out of the original four (4) groups composed of twelve (12) students from CPU-Iloilo City, only two (2) groups involving six (6) students were able to conduct studies on transportation engineering. The data gathered by two other groups were utilized in the completed research of both institutions. The collaboration has helped the student groups from both institutions to finish their civil engineering projects on time. It has provided opportunities to help a local community as well as disseminate information to other communities through the presentation of the research papers in national and international conferences. Overall, the research collaboration was considered successful.

ABSTRACT


This study focuses specifically on the determination of electrical noise or harmonic level generated by the variable frequency drive controller in terms of its amplitude and frequency. The central area of concern is the effect of harmonics on the power quality of the electrical supply of Central Philippine University at the point of the pump-motor equipment.Based on the results of the tests, the harmonics of the supply voltage was 2.25%. Running the 5-HP motor directly produced a lower harmonics of 2.10%. When the controller was used to run the motor, the controller in itself produced a significant level of harmonics of 8.42%which interferes with nearby electronic appliances within a very close proximity. A substantial part of the harmonics produced by the controller is filtered from going out of the device itself, so that the harmonic level at the source terminal was about 3.93 %, showing an increase of 1.83% compared to running the motor without the use of the controller. The value is within the acceptable limits of 5% for electronic circuits and systems, but not acceptable for medical and other related highly sensitive instruments, which require a total harmonic distortion (THD) of not more than 3%.

ABSTRACT


Cooperative Education or Co-op is an immersion program which allows engineering students to gain professional work experience while still in college. Co-op work experience provides students with the opportunity to explore career interests and goals, use the workplace as their classroom, and gain professional development. This paper describes how the CPU College of Engineering Six Year Engineering program integrates Co-op education into its curriculum. This paper is intended to give the description, mechanics and evaluation of the impact of the six-year degree program herein referred to as the Co-operative Education Program. Co-op Education students are allowed to enroll in this engineering program by selection criteria of top (20) percent of the class. Overall student evaluating Co-op experience was 47.78 percent (good). The six-year engineering curriculum and teaching approaches are aligned with and responsive to the needs of the industry.

ABSTRACT


The production and consumption of ready-to-drink health beverages have increased in recent years because of greater demand for health benefits. Central Philippine University (CPU) engaged in a study of lemongrass (Cymbopogon citratus Stapf.) with Kalamansi-Ginger formulation to determine its sensory, chemical and microbial characteristics. Methodology involved sensory analysis in terms of turbidity, flavor and general acceptability; chemical analysis in terms of citral content, titrable acidity and anti-oxidant activity; and microbiological analysis in terms of total counts of bacteria and fungi, as well as shelf-life. Generally acceptability mean scores for sensory evaluation of beverage samples decreased with longer storage period in both room temperature and controlled temperature. Chemical analysis on citral content, titrable acidity and antioxidant activity changed through time, with freshly prepared beverages having the highest values. Microbial analysis revealed fungi count but no bacterial count for a formulation stored in glass bottles. Shelf-life is 17 days for both ambient room conditions at 27ºC average temperature and at controlled incubator temperature. These characteristics make lemongrass acceptable as a ready-to-drink beverage product for production and consumption.

ABSTRACT


Understanding basic electrical circuit principles can be difficult for students taking up basic electrical engineering course. Enhancing learning methodologies requires experiments with adequate laboratory equipment. The lack of basic equipment required for these laboratory experiments hinder students from learning and fully comprehending their lessons. Affordable and locally designed equipment is needed as a substitute for the expensive technology that many schools in the Philippines cannot afford. This study is aimed to design, construct and test a low cost Three-Phase Low Voltage Variable Power Supply for Electrical and Electronics Laboratory with the following components: three-phase high voltage power supply of 220VAC, low voltage variable three-phase AC power supply with an output of 3V, 4.5V, 6V, 9V, 12V and DC output of ±12V, +5V, ±1.25V – ±12V. Central Philippine University College of Engineering requires laboratory subjects to facilitate and enhance learning methodologies. All output was provided with overcurrent circuit protection to protect the circuits and the components from overload and accidental short circuit. Result shows that all data have met the requirements for reliable, accurate and ready-to-use power supply equipment. The construction of the circuit was completed, thereby meeting the needs of the electronics and electrical students for a Three-Phase Low Voltage Power Supply.
