sampling technique because they were selected by 
adjusting to certain considerations or characteristics.  
3 RESULTS 
The students' knowledge shows that conventional 
cigarettes (kretek) and e-cigarettes contain nicotine 
and could cause health problems, such as respiratory 
tract. This problem occurs because cigarette smoke 
passes through the respiratory tract several times. 
Another health consequence is lung disease, such as 
cancer. The students who smoke conventional 
cigarettes (kretek) and those who smoke e-cigarettes 
argue that smoking is permissible as long as they have 
been 18 years old. Moreover, they argue that it is 
common and reasonable for adolescents aged 18 
years to smoke. The family will rebuke their children 
who smoke kretek or e-cigarettes. However, smoking 
is a common activity at several events, such as 
wedding parties. 
Conventional cigarette (kretek) smokers argue 
that smoking by burning tobacco is considered gentler 
and gives a different sensation. Besides, they could 
buy the cigarettes at retail (per bar) as almost all small 
shops or stalls provide retail cigarettes at a more 
affordable price and easy access. In contrast, e-
cigarette users argue that e-cigarettes are only 
expensive when purchasing the tool. However, the 
tool could be used many times so that the price is 
affordable. Moreover, e-cigarettes could be 
purchased online or offline, though the offline store is 
not massively found. E-cigarette liquid offers more 
flavor and is odorless when used. Finally, they opine 
that e-cigarettes are small in shape; thus, they are 
easily brought everywhere.  
4 DISCUSSIONS 
Individual behavior is influenced by several factors, 
such as knowledge, attitudes, and reinforcing factors, 
including peers and family (Romijnders et al., 2018). 
Knowledge and positive attitudes support a person to 
perform behavioral changes. In the globalization era, 
using e-cigarettes becomes reasonable even though 
they cause as hazardous impacts as conventional 
cigarettes (Sudradjat, 2019). Therefore, it is necessary 
to develop preventive strategies for cigarette use in a 
campus environment to increase the productivity of 
graduates and prevent the health effects caused by 
cigarettes. Moreover, it is necessary to develop 
strategies to stop smoking behavior, such as peer 
development for health education (Moshki, Zamani-
Alavijeh, & Mojadam, 2017), engagement of 
electronic media on mobile phones (Larsen, Nicholas, 
& Christensen, 2016), and the use of hypnotherapy to 
quit smoking (Hypnoterapi, 2019 
5 CONCLUSIONS 
Some respondents prefer using e-cigarettes because 
they are easily bought, could be purchased online, 
only offer expensive prices at the beginning of buying 
the tools, could be used repeatedly, offer various 
flavors and odorless, and come in small shapes. 
Meanwhile, some respondents prefer conventional 
cigarettes because they give a distinct sensation of 
burning cigarettes, offer quite affordable prices, are 
available in retail, are easily accessed, and have more 
gentle looks.
