Improper waste disposal on rivers is a significant environmental issue that has a harmful impact on our planet. The waste that is dumped into the river can contaminate the water, harm aquatic life, and disrupt the overall balance of the ecosystem. As researcher, it is a must to have a critical role in helping to address this problem. By conducting studies and developing innovative solutions, researchers can help mitigate the impact of river pollution and work towards a sustainable future for our planet. Through collaboration with other stakeholders, it can create a comprehensive approach to tackle this issue, including waste management strategies, policy recommendations, and community engagement initiatives. By taking action to address improper waste disposal on rivers, we can protect our planet's valuable natural resources and ensure a healthy environment for future generations. The study A LOW-COST AUTOMATIC POLLUTANT-COLLECTOR RETRIEVAL FOR AQUATIC SYSTEMS (LAPRAS) aims to develop and design a water waste collector. It involves the effectiveness of the device in getting waste and the amount the device can accumulate in one turn. The research includes evaluating the level of acceptability of the device based on ISO 20510. The researchers used a developmental and descriptive approach with the goal of designing, developing, testing, and modifying any problems discovered throughout the testing period. The researcher’s modified questionnaire was used and distributed to 40 respondents to evaluate the performance of the device. These strategies were used to discuss the study's findings in relation to the objectives. Evaluation of Acceptability of Low-Cost Automatic Pollutant-Collector Retrieval for Aquatic Systems (LAPRAS) in terms of its usefulness, reliability, durability, and portability. 3.1 In terms of usefulness, the system got an average weighted mean of 2.683 and was verbally interpreted as accepted 3.2 In terms of reliability, the system got an average weighted mean of 2.692 and was verbally interpreted as accepted. 3.3 In terms of durability, the system got an average weighted mean of 2.542 and was verbally interpreted as acceptable. 3.4 In terms of portability, the system got an average weighted mean of 3.933 and was verbally interpreted as highly accepted. The researchers found out that the designed and constructed device performed its function less efficiently in terms of speed, mobility, and power. The volume of water, the current of water, the air current, and certain parts machine affect the movement of the device. Based on the results of the study, “A LOW-COST AUTOMATIC POLLUTANT-COLLECTOR RETRIEVAL FOR AQUATIC SYSTEMS (LAPRAS)” performed well and still has room for improvement in many aspects. In addition, the survey was properly conducted. Other researchers wishing to conduct related research are encouraged to do further research and consider other concerns such as automation, use of renewable energy, and environmental friendliness of the device when implementing.
