Abstract
In this study, the purposes of this research were to study and compare knowledge about waste and sewage management, environmental ethics and environmental volunteers using question and problems-based learning, before and after class of undergraduate students, to compare knowledge about waste and sewage management, environmental ethics and the environmental volunteers of undergraduate students with different gender and Grade Point Average (GPA). The sample used in the research were 111 undergraduate students being selected by purposive sampling who were enrolled in the course control waste and sewage in the 1st semester of the academic year 2019. The research tools were a learning activity plans on solid waste and sewage management using question and problems-based learning, knowledge test on waste and sewage management, environmental ethics test and environmental volunteers test. The statistics used in the research were frequency, percentage, mean, standard deviation, including hypothesis testing using t-test, F-test (One-Way MANOVA, One-Way MANCOVA) and Univariate Test. The results showed that: (1) The undergraduate students had an average score of knowledge about waste and sewage management, environmental ethics and environmental volunteers in the posttest was higher than the pretest statistical significance (p < .05); (2) There was no different of knowledge score of waste and sewage management, environmental ethics and environmental volunteers of undergraduate students with different gender (p > .05); (3) There was statistical significant different of knowledge score of waste and sewage management, environmental ethics and environmental volunteers of undergraduate students with different Grade Point Average (GPA) (p < .05).

The research tool was a learning activity plans on waste and sewage management, knowledge test, environmental ethics test and environmental volunteers test using the tools created to consult with an advisors, send 5 experts to determine the consistency of the communication and evaluation tools, after that try out with undergraduate students who are not sample
Summary
Garbage problem is a major problem that tends to become more serious which is caused by the increase in the population. The problem of waste or garbage is an important reason to cause problems such as air pollution, water pollution, disease vectors and make the scenery not beautiful. The National Solid Waste Management Master Plan (2016-2021) has been developed to resolve the solid waste problem in accordance with the government policy. Have to choose a variety of teaching methods to encourage students to seek additional knowledge from books, textbooks or learning resources in the community. This will help students to achieve complete learning and create desirable behaviours or characteristics in students relatively permanently (Patcharee, 2008)
