Evaluation of the Performance and Skills of the Civil Engineering Students Batch 2023 and Civil Engineering Instructors of Don Honorio Ventura State University with the Transition of Different Learning Setups

The government decided to temporarily close all educational institutions due to the COVID-19 pandemic for the protection of students, teachers, and the school community. This paper intended to evaluate the performance and skills of the Civil Engineering Students Batch 2023 of Don Honorio Ventura State University and Civil Engineering Instructors who experienced the transition of education to different learning setups. A descriptive-quantitative study design has been utilized wherein analyzing data, statistical treatments such as weighted mean, standard deviation, and analysis of variance, were used in order to identify the particular problems. Survey questionnaires were used in this study where 251 4th-year Civil Engineering Students and 14 Civil Engineering Instructors served as the respondents. The results revealed that the traditional learning setup was found to be the most effective platform for the students and instructors that suits their chosen program. While the students’ performance and skills during online learning varied in terms of adaptability and convenience. Blended Learning is the balance method between traditional and digital learning approaches. On the other hand, the level of agreement of the instructors in the Civil Engineering Department regarding the different educational setups also varied. They generally prevailed that face-to-face classes were the most efficient way to impart proficiency on certain topics and enhance students’ skills with regard to the civil engineering program. The results will serve as the foundation for developing an academic intervention program for Civil Engineering Students in order to adapt to the academic transition Keywords: Transition, Different Learning Setups, Performance, and Skills

Investigating the effect of waste cooking oil and waste engine oil on aged bitumen

In order to determine if used engine oil and used cooking oil can be used to recycle old asphalt, the impact of these substances on the improvement of the material's physical properties was investigated. Aged asphalt binders with 5 hours of aging were obtained using an indoor test simulation with the Thin Film Oven Test (TFOT) at 163°C. Then, three different dosages of waste engine oil and waste cooking oil were added to investigate performance improvements. The findings clearly demonstrated that waste engine oil and waste cooking oil could effectively soften and recover the workability of aged asphalt. Furthermore, if the content of waste engine oil or waste cooking oil was appropriate, the performance of aged asphalts could be improved to that of virgin asphalt. Overall, the good applicability would provide waste oil with a much broader range of services in the asphalt pavement recycling field. It also provided a method for creating a new rejuvenating agent using the two waste oils to improve the properties of bitumen. Furthermore, it realized waste recycling and environmental protection.

Plastic waste bottles and bamboo powder sawdust as a partial replacement for fine aggregates in the production of concrete hollow blocks

Polyethylene Terephthalate (PET) and Bamboo Sawdust take an exceptionally long time to decompose. These wastes can cause detrimental pollutants that can have an impact on the environment in the remote future. To help decrease pollution, these substances can be used as an alternative material in producing concrete hollow blocks which are a key item used in construction. The purpose of this study was to test the performance of PET particles and bamboo sawdust as an example partial replacement for the use of fine aggregates in the manufacture of concrete hollow blocks. PET plastics were cut into small pieces at least 1 mm in diameter and bamboo powder sawdust was collected. Both the compressive strength and weight classification percentage were determined by testing the hollow blocks. Four set-ups with differing percentages of PET particles (0, 5%, 10%, 15%) with BSD (1%) were prepared to partially replace the volume of sand. The block dimension was 4in x 20cm x 40cm and a 1:4 cement-to-sand ratio having a 0.5 to 0.55 water-cement ratio was used. Forty-eight (48) hollow blocks were produced and underwent curing times of 7, 14, and 28 days and were examined afterward. According to the findings of the study, it was seen that as the alternative materials in the blocks decrease, their respective compressive strength increases. There were no consistent results observed with the density. The CHB with 5% PET and 1% bamboo sawdust cured for 7 days was discovered to be the desirable proportion in producing CHB as it obtained the highest average compressive strength and greatly reached the required average tensile strength of the Department of Public Works and Highways (DPWH) and ASTM C129

Competency-based assessment of the civil engineering program under the new learning modalities: A multi-perspective triangulation analysis

In a rapidly advancing world, civil engineering students should be able to adapt to the dynamic competencies valued in the industry to succeed in their future careers. This study aims to fill a research gap by analyzing the competencies acquired through the new learning modalities. Its significance extends to multiple sectors, providing growth for students, improving teaching methods for faculty, informing hiring decisions for construction companies, enhancing educational systems for universities, assisting curriculum programmers, and offering insights for future researchers. The study examined the competencies of civil engineering students under new learning modalities, exploring self-assessments, professors' perspectives, and construction companies' viewpoints, it also uncovered the intricate relationships between these perspectives. Additionally, this study compared the acquired competencies of students with the valued competencies in the industry. This study utilized a mixed-method research design, specifically triangulation. The study surveyed eighty (80) students, sixteen (16) faculty members, and ten (10) construction companies through a purposive sampling technique. Validated questionnaires and structured interviews were used as research instruments. Furthermore, the quantitative and qualitative data were analyzed accurately and systematically. The findings of the study revealed that civil engineering students possess a strong foundation in ethical responsibilities, teamwork, and leadership, as mentioned by the participants, who believe that ethical responsibilities have been instilled in students since childhood. However, the students also demonstrate a need for further development in engineering mechanics, design, and managing risk and uncertainty. From the perspective of professors and companies, students need to have knowledge and mastery of design, risk, and uncertainty which are valued competencies in the industry. In conclusion, the study emphasizes the significance of aligning academic and industry expectations for preparing successful civil engineering students. While competencies from new learning methods are generally effective, technical improvements are required. Varying perspectives highlight the need for an enhanced curriculum to meet industry demands, with strong support for the formal integration of hybrid learning.

Waste Plastic Brick

Brick is one of the very common and important construction materials which is used in all masonry work. A large land area is used. for acquiring the clay for brick making. The word replacement has become a very common thing worldwide. More land area is being acquired for clay in brick making. This paper outlines the utilization of plastic waste in construction industries. Plastic waste use in the construction industries is increasing rapidly and the world’s recycling rate of either plastic waste specifically is still low. The production of bricks is non-eco-friendly and a waste-generating process because of the greenhouse gases released. Utilizing plastic as construction materials, especially in the production of bricks is one of the promising steps towards sustainable resources and waste management. Plastic waste can substitute either partially or completely one or more of the materials in brick production. To make this reduced replacement of waste materials can be done. This was then molded into bricks with a mold of size 190x90x90 mm. Further research based on recent research and a better understanding of the utilization of plastic waste in bricks is needed to produce high-durability and quality bricks as well as to achieve the optimum balance in all aspects, especially in terms of cost and functionality.

Proposed Design of the Existing Dike along Sitio Delta, Consuelo, Macabebe, Pampanga

Dikes are structures that prevent overflow to the inland ground and must be built on a continuing basis to protect flood-prone areas. To have a long service life, dikes must be built according to design standards, and failure to do so my result in the structure failing. Failure on some parts of Consuelo Dike motivated the researchers to come up with the study. The present project study aimed to propose a redesign of the dike along Sitio Delta, Consuelo, Macabebe, and Pampanga. Before determining the parameters needed in designing, the researchers identified first the causes of the failure of the dike through the gathered or collected data from the respondents’ observations and experiences. Then, researchers assessed the present condition of the existing dike through site analysis and actual observation. The data collection procedure was carried out by obtaining secondary data from the Municipality of Macabebe and the Department of Public Works and Highways (DPWH). This includes the result of soil sample tests, past maximum flood levels, river profiling, geotechnical investigations, and other tests made regarding the dike. The findings of the study helped the residents of Barangay Consuelo deal with the consequences of dike failure. The findings provided useful data to the Local Government Unit of Macabebe, Pampanga, which can be used as a reference and guide to the development of the existing Consuelo Dike design. Researchers may use the findings to identify additional areas of concern and recommend appropriate interventions.
