This study aimed to describe the ethical problems, valuable experience, and ethical
decision-making abilities about the environment by students through the application
of OIDDE models on integrated field studies abroad. Descriptive data analysis
techniques were used on existing data. Environmental ethical problems that arose are
the use and exploitation of natural resources, pollution, lack of public facilities’
cleanliness, poaching, and environment arrangement problems. Valuable experiences
gained by students were: 1) Malaysia Highway Rest Area: plants flourish and the
birdlife is undisturbed; 2) Malacca River: transformed into a clean and beautiful area;
3) Putrajaya: concerns raised about environmental balance and sustainability;
4) Sentosa Island: various modern amusement rides prepared for enjoyment in line
with environmental principles. Ethical decisions taken were: 1) environmental
functions and sustainability should be referenced in development; 2) amusement rides
developed in line with environmental consideration; 3) pattern of consumption and
human activities to avoid resultant pollutants as much as possible; 4) use of
environmentally friendly facilities should become a lifestyle choice; and 5) consistently
implement environment regulations
