Promises, in the view of the promises ethics, are a specific obligation that forms
engagement with other parties who receive the promises. This engagement morally raises
obligation that the promises made by others should be kept. Berry stressed that the basis
for maintaining relationship in services is the promises that has been made to the
customer. For service providers it has implications for the three activities namely make
unrealistic promises, keep and fulfill the promises at the time of the delivery the services
with an effort to allow the promises on the service system being built to meet those
promises (Mohr & Bitner, 1995). The three important marketing activities to do the
efforts are external marketing, interactive marketing, and internal marketing. The concept
shows a linkage group that work together to develop, promote and deliver services that
are referred to as key actors.
Various studies relevant to the promises ethics can be summarized as follows: (1)

concludes that honesty is a part of fairness and openness, and communicating it properly

that ethical policies relating to the development of ethics in the organization that enable
organizations to carry out their responsibilities, (5) (Taufani, 2010) concludes that the
most important ethical aspects that play a role in making promises is the clarity in the
promises delivery. The most important ethical aspects that play a role in enabling the
most promises is the seriousness and responsibility in providing the system for students.

polytechnic. In this study, it was used a range of time (time horizon) which was one shoot
with the type of cross-section data. The descriptive hypotheses test used Weighted Mean
Score / WMS. In the verification study with the approach in modeling and solution
techniques to be used as a tool of analysis was a method of Structural Equation Modeling
(SEM) based on a variant or a component, namely the Partial Least Square (PLS).
The population in this study is the overall characteristics of the study variables
perceived by the students of the Polytechnic. The unit of analysis is 31 Polytechnics,
