An experimental study on utilizing bioenzymes from fermented orange peel (citrus reticulata) waste as replacement for stabilizers for soil in road pavements
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringRoad transportation plays a pivotal role in every civilization and nation. Soft soil is a primary contributor to pavement failures due to its inability to maintain its original shape and develops stress along its physical and geotechnical characteristics. In hindsight, various soil stabilizers have emerged in civil engineering, including the utilization of bioenzymes. The study investigated the effectiveness of varying dosages of bioenzyme from fermented orange peel (Citrus reticulata) waste as soil stabilizer in a seven (7-day) curing period. The potential of hydrogen (pH) meter, biochemical oxygen demand (BOD), and chemical oxygen demand (COD) content through a titrimetric method and a closed reflux method characterized the waste of fermented orange peel
(Citrus reticulata) . The obtained data were analyzed and investigated in terms of consistency, compaction, California bearing ratio (CBR), and swelling. The result demonstrates that 20 mL/50 kg of bioenzyme is the optimum dosage for the selected soft soil for maximum dry density (MDD) and swelling. In contrast, the 25 mL/50 kg dosage of bioenzyme has shown minimal improvements on the selected soft soil in terms of optimum moisture content (OMC) and plasticity characteristics. The present study concludes that the overall results have shown nominal improvements, yet it needs to conform to the standard subgrade requirement for road pavements. Moreover, further examination of the effects of bioenzyme in various curing days and the use of higher dosages may also help in utilizing the soil to conform to the standard subgrade requirement

cepstral coefficient delta features in KNN for bird calls classification
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Electronics EngineeringIn ecosystems, avian species, especially apex predators such as the Philippine Eagle and Pinsker's Hawk Eagle, play a crucial role in regulating other species and fostering biodiversity. These bird species actively manage populations of smaller carnivores, thereby making significant contributions to the overall health and balance of the ecosystem. If these species disappear, there would be no suitable replacements, negatively impacting the
ecosystem. Protecting and monitoring birds and their habitats are crucial for ecosystems and human well-being. Therefore, the researchers developed an acoustic monitoring system for endangered Philippine raptors using a recorder and a computer program. In a rainforest environment, specifically at the Philippine Eagle Center, the researchers employed a portable, battery-powered recorder to capture bird calls continuously. Subsequently, a computer program was utilized to automatically filter, detect, and classify these calls. The
analysis results were exported into a spreadsheet for monitoring purposes. To predict bird species, delta features of Mel Frequency Cepstral Coefficients (MFCC) and Gammatone Cepstral Coefficients (GTCC) were utilized as features. The Cosine k-nearest neighbors (KNN) algorithm was employed for classification, resulting in an overall accuracy performance of 97.42%. Specific accuracy rates for each bird species were also achieved:
Brahminy Kite (100.00%), Philippine Serpent Eagle (98.41%), Pinsker's Hawk Eagle (99.58%), Philippine Eagle (95.83%), and White-bellied Sea Eagle (91.86%)
