EXECUTIVE SUMMARY: This study Development and Waste Collector with Segregation Systems provides a floor cleaning and waste collecting device with a segregation system. The study aimed to design and construct a device of waste collecting and waste segregating to be used by homeowners, students and utility and maintenance personnel to clean floors of any establishment facilities. Specifically, this study aimed to design and develop a device that serves as a waste collector with a waste segregation system and an alternative waste collector and waste compartment for large waste using a mechanically-operated waste wiper and a motor-based waste pan test the performance of the device in terms of the accuracy on segregating waste and the precision on collecting waste and determine the level of acceptability with respect to design, functionality, usefulness, and safety and maintenance of the device. To achieve the objectives of the study, the researchers utilized the developmental and descriptive-evaluative research design. The researchers used record sheets to test the performance of the device. The device underwent ten (10) trials each in terms of accuracy and precision. The researchers used four (4) record sheets in total, two (2) for accuracy designated for metal and paper/plastic waste, and two (2) for precision also for metal and paper/plastic waste. Each trial represents a tenth percent (10%) and in a total of a hundred percent (100%) and data obtained was recorded, evaluated and interpreted. After testing the performance in accordance of the accuracy and precision of the device, the recorded data were evaluated 62.5% accurate for metal waste and 90% accurate for paper/plastic waste and verbally interpreted as less accurate and very much accurate respectively. As for precision, it was evaluated 80% for metal waste and 100% for paper/plastic waste and verbally interpreted as much precise and very much precise respectively. The overall results of the record sheets shows that the developed device performed well in terms of accuracy and precision. Furthermore, the researcher-made questionnaire-checklist was used for the evaluation of the level of acceptability of the developed Waste Collector with Segregation System in terms of design, functionality, usefulness, and safety and maintenance. Two groups of respondents were considered which are the end-users and the experts. The first group which consisted of fifteen (15) end-users that composed of utilities, homeowners and students. The second group which consisted of five (5) experts composed of Electronics and Electrical Engineers. The researcher used the five (5) point Likert Scale to determine the responses on the questionnaire checklist. The scale, ranges of the weighted mean and verbal interpretation by referring to the objectives. As evaluated by the end-users, the device got an overall mean of 4.69 and as evaluated by the experts, the device got an overall mean of 4.36 and both verbally interpreted as very much accepted in terms of design. The results show that the device satisfies the respondents based on its design. Furthermore, as evaluated by the end-users, the device got an overall mean of 4.69 and as evaluated by the experts, the device got an overall mean of 4.36 and both verbally interpreted as very much accepted in terms of design. The results show that the device satisfies the respondents based on its functionality. Moreover, as evaluated by the end-users, the device got an overall mean of 4.654 and as evaluated by the experts, the device got an overall mean of 4.8 and both verbally interpreted as very much accepted in terms of usefulness. The result show that the device satisfies the respondents based on its usefulness. And as evaluated by the end-users, the device got an overall mean of 4.67 and as evaluated by the experts, the device got an overall mean of 4.6 and both verbally interpreted as very much accepted in terms of safety and maintenance. The results show that the device satisfies the respondents based on its safety and maintenance. And after the researchers tallied the results of the questionnaire checklists, the device gathered the overall means of 4.69 for the end-users and 4.51 for the experts and both verbally interpreted as very much accepted. The results show that the overall developed device is very much accepted by the respondents in terms of design, functionality, usefulness, and safety and maintenance.
