way to a sustainable banana crate
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringFor years, Mindanao has been the largest source of bananas throughout the country. Aside from that, we supply more than 90% of bananas, and tons of our supplies are also exported. The demand for bananas is increasing, but the material for storing and transporting them is deteriorating. Hence, alternatives to this product are called for. Furthermore, this study aims to examine the banana pseudo-stem fiber slab properties in different ratios. It seeks to determine an adequate proportion of banana fiber mixed with the epoxy mixture at the ratio of 1:1, 1:1.25, and 1:1.5, respectively, and to compare its cost and properties to the traditional wood crates. This study will design and assess the properties of traditional wood crates and banana fiber slabs reinforced with epoxy composites in different ratios. Universal Testing Machine assessed the samples' tensile and compressive strengths. The result of the study found that among the three proportions, the ratio of 1:1.5 shows the best performance. Moreover, the designed crate is 175% more expensive than the traditional crate; however lighter, has a higher storing capacity, and has a longer period of fire resistivity. These results indicate that the ratio of 1:1.5 banana fiber slab-reinforced epoxy composites is a potential alternative to traditional wood crates

Influence of activated charcoal in the enhancement of adsorbency of air pollutants emitted by vehicle exhausts in asphalt concrete
No full textVehicle emissions are the pollutants produced by a car engine during the combustion process, which include nitrogen oxides (NOx), carbon dioxide (CO2), hydrocarbons (HC), carbon monoxide (CO), and other air pollutants that are damaging to the environment and human health, particularly in urban areas. Since activated charcoal was proven effective in increasing the adsorption of harmful pollutants when mixed with concrete cement, this research aims to investigate if it has any effect on adsorbing other air pollutants when combined with asphalt concrete. For this study, the students made a prototype sealed chamber laid with a strip of asphalt concrete mixed with activated charcoal. The specimens were subjected to smoke emission tests to measure the air pollutants level, such as carbon monoxide. The researchers obtained the standard properties, compressive strength of asphalt concrete mixed with activated charcoal, and the reduction level of carbon monoxide when exposed to modified asphalt concrete. The result shows that adding activated charcoal to asphalt concrete would significantly enhance its absorbency in air pollutants such as carbon monoxide. This could be a potential way to combat or aid in lowering the number of harmful air pollutants caused by vehicle exhaust

No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in ArchitectureA degradation in the area's value as a travel destination and losses in social significance could severely impact the local economy over the long run if the quality of the coastal infrastructure deteriorates. Poor design can drastically impair a building's functionality and, in some cases, can significantly limit its usable lifespan. Participant and perception surveys have become widely used to evaluate the quality of beaches for recreational reasons. It is vital to comprehend how the general public views and responds to effectively identify the areas of concern. Although people may have a variety of different and inconsistent points of view, it may be challenging to evaluate user perspectives in this case. Therefore, this research aims to investigate the relationship between the design quality and users' perspective of the coastal establishments in barangay Matina Aplaya, Davao City. This study used a quantitative approach to collect the necessary measurable data and information for this evaluation. It would utilize a correlational research design to evaluate the relationship between the two variables: the establishment's design quality and user perspective. The researcher would randomly select a subset of participants using simple random sampling. Spearman rank correlation revealed a significant correlation between the two variables. The result shows a positive relationship, rejecting the null hypothesis of no significant relationship. Therefore, the coastal establishments in barangay Matina Aplaya, Davao City, will still need an improvement in the design quality of their facilities to have a much better outcome on the hospitality industry and impact not just people but also the environment
Effects of kapok fiber and bamboo leaves ash as soil stabilizer for expansive soil in road application
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringClayey soils pose a risk and damage to life and property and are unsuitable for direct engineering application due to their shrink-swell behavior. Pavement cracks and swells are some effects due to soil excessive distress under volumetric changes of its underlying soil. With this, researchers explore different methods to stabilize expansive soils using fibers and cementitious materials. This paper used Kapok Fiber (KF) and Bamboo Leaves Ash (BLA) as soil stabilizers. It seeks to determine the soil classification, test its effects on compaction, investigate the swelling of the soil and change of consistency. Varying concentrations are 0.5% KF and 6%BLA, 0.8% KF and 6%BLA, and 1% KF and 6%BLA by weight of the soil. Test samples undergo sieve analysis, Atterberg limit, compaction, and swell index test. Results revealed that adding fibers to the soil matrix increases maximum dry density (MDD) while optimum moisture content (OMC) varies indirectly. In addition, soil swelling decreases after adding KF and BLA with an optimum design mix of 0.5% KF and 6%BLA. T-test showed that swell index under 10, 30, and 65 blows significantly differ between the control and the optimum ratio. Furthermore, the consistency of the soil changes from highly plastic to low plasticity. Therefore, KF and
BLA are good sources of soil stabilizers for pavement subgrade purposes

No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringNatural disasters are all expected to worsen and happen more frequently because of global warming. Cities containing a large portion of the human population were particularly vulnerable to the effects of climate change. Creating future climate projections can lessen the impact of these adverse occurrences. In this study, rainfall and temperature projections from Coupled Model Intercomparison Project Phase 6 (CMIP6) were used to predict the future climate data of Tagum City. To project precipitation and temperature from 2020 up to 2100, an ensemble of 31 Global Climate Models (GCMs) under two Shared Socioeconomic Pathways (SSPs) (SSP2-4.5 and SSP5-8.5) were utilized. The ACCESS-CM2 model corresponded satisfactorily with the PAGASA weather station's observed rainfall dataset. The resulting flood risk map shows that, in the current scenario, 7.1% of the city’s land area belongs to the ‘very low’ flood risk category, 22.3% belongs to the ‘low’ category, 22% belong to the ‘medium’ category, 37.5% belong to the ‘high’ category, and 11.1% belong to the ‘very high’ category. It also shows that 13 of the 23 barangays belong to the ‘high’ and ‘very high’ flood risk categories for current and future scenarios. These barangays would be the ones to require the most immediate attention from decision-makers to develop strategies for future occurrences of flood within the city of Tagum
