Socio-Demographic Assessment of Surrounding Community to a Material Recovery Facility (MRF) and a Dumpsite: The Case of Lapu-Lapu City, Philippines

This study assessed the socio-demographic profile of surrounding community to a Material Recovery Facility (MRF) and a dumpsite in Lapu-Lapu City, Philippines. A total of twenty-two (22) households were interviewed using survey questionnaire instrument assessing household profile, opportunities, water resource and utilization, health status and services, waste management practices, and perception to disposal sites management. Result showed that most of the households were scavengers, microfinance businessmen, and material recovery facility (MRF) contract workers earning below the per capita poverty threshold. Prevalence of diarrhea, gastrointestinal, and respiratory diseases were likely common and medical services availed were largely dependent on barangay clinic and government hospitals. The use of groundwater for bathing, washing, cleaning, and cooking other than drinking exists. Domestic waste disposal of the surveyed households were complex involving collection, dumping elsewhere, recycling, and burning. Considering the current condition of the studied area it is recommended to establish an analysis on the impact of the MRF and the dumpsite to the groundwater resources and comprehensive health evaluation among households

Comparative Study between Computer Simulated and Hands-on Physics11 (Electricity and Magnetism) Experiments

A major research domain in physics education is focused on studying the effects of various types of teaching interventions aiming to help student's alternative conception transformation. The purpose of this study was to compare the changes of conceptual understanding of Physics 11 (electricity and magnetism) laboratory in Computer simulated laboratory application (CSL) and Hands-on laboratory application (HLE) in the University of Science and Technology of Southern Philippines (USTP), formerly Mindanao University of Science and Technology (MUST). In this study, a total of 194 students were randomly selected. Two parameters were set for this study: (1) gender of the respondent; and (2) college the respondents were enrolled. The result presented that CSL with 54% was the most preferred applications as alternative instructional tool in understanding the concepts of physics. Sparingly, about 46% of the surveyed respondents favored HLE. However, no apparent differences appeared with respect to the questions on the conceptual understanding learning objectives. Overall, there was no significant difference between CSL and HLE regardless of the gender ( p=0.81, p=0.90, and p=0.90)

Drinking Water Quality of Selected Tap Water Samples in Cagayan de Oro (District II), Philippines

This study was conducted to preliminarily determine present drinking water quality of selected District II communities in Cagayan de Oro, Philippines. Five community stations (total twenty stations) were established covering three months tap water monitoring. All samples were analyzed using portable meters determining the pH, dissolved oxygen (DO), temperature, conductivity, salinity, turbidity, and total dissolved solids (TDS) Overall, all studied tap water samples from selected stations passed the drinking water regulations except for conductivity (Risk quotient>1). Similarly, both pH and turbidity analyses showed a sampling date specific variations (p<0.05) while the analyses of temperature and salinity showed station specific variations (p<0.05). A strong correlation of studied parameters was also found between conductivity-salinity (r = 0.98); conductivity-TDS (r = 0.90); and salinity-TDS (r = 0.92). Extrapolating from this it can be concluded that the tap water samples were safe to drink. The study was preliminary and further analyses incorporating metals, pathogens, and organics may be needed
