Adsorption of methylene blue by magnetized achiote (Bixa orellana) pericarp ash: Effect of pH and kinetics
Arellano, Jeramay, M. (Davao del Sur State College, 2024-06)
Wastewater management has long been a significant issue for society. In the Philippines, achiote pericarp is often considered an agricultural waste. It is typically left in open fields or burned in the open air near the trees where they are harvested. This study explores the potential use of this waste material (achiote pericarp ash, APA) in removing dye from liquid solutions. To improve the adsorption capacity of APA, it is necessary to incorporate Fe3O4 into it. This will enhance its ability to effectively adsorb Methylene blue solution. To address this, APA had been impregnated with Fe3O4 nanoparticles to produce magnetized APA (MAPA). The APA used in this study was sourced from the farmlands of J. P. Laurel Malungon, Sarangani, Philippines. An adsorption experiment was thoroughly conducted, investigating the effects of pH and kinetic changes. The MB adsorption process was found to fit with a pseudo-quadratic model, with maximum adsorption observed at pH 10. The identification of functional groups presents before and after magnetization was conducted using Fourier transform infrared spectroscopy (FTIR). Among theme were -OH (intramolecular H-bond), O=OH (phosphorus oxoacid), -CO-CH3 (ketone), -OH (primary alcohol), and -SiCl3 (silicon compounds). These findings encourage farmers to reuse agricultural waste as a valuable product. Future related research could investigate the use of a different dye color or another type of biomass. Ultimately, this investigation provides significant knowledge about the potential role of agricultural by-products for wastewater treatment processes.

Personal disposition and teacher related factors towards performance in mathematics
Daligdig, Kyla B. (Davao del Sur State College, 2024-06)
This study aimed to investigate the correlation between personal disposition and teacher related factors, towards performance in mathematics among grade 10 students at Hagonoy National High School. A quantitative-descriptive correlational study was conducted on a total of 191 students participating in the study, responding to a questionnaire assessing their personal disposition and teacher-related factors. The results showed a significant positive correlation between personal disposition, particularly in terms of interest and study habits, and mathematics performance. However, no significant relationship was found between teacher-related factors (personality traits, teaching skills, institutional materials) and mathematics performance. This suggests that while teacher related factors may not directly correlate with mathematics performance, there exists a positive correlation between personal disposition and mathematics performance. Enhancing students' personal disposition towards mathematics is crucial for improving academic performance. Additionally, the lack of significant correlation with teacher-related factors implies that other variables or factors beyond teachers' characteristics and classroom practices may play a more influential role in determining students' academic performance in mathematics. Therefore, a comprehensive understanding of these factors is essential for improving mathematics education beyond traditional measures of teacher quality and classroom effectiveness.
