Abstract :
E-marketplace is defined as an online trading place for goods and services
that is managed by one party, the developer, then the product in it is provided by
the other party, the seller. In an event, there is usually a guest star requested by the
event organizer to appear as the performer. Event organizers often find difficulty
to find a guest star that suits their needs for the show, on the other hand the
performers such as musicians, dancers and others also have difficulty in promoting
their services. Weighted product method can be applied to the decision support
system for determining guest on a web-based e-marketplace. The aims of this thesis
are to provide an alternative decision to choose a guest star that fits the criteria
using the weighted product method and create an online market to get a guest star
that is as expected. There are three criteria used to determine the guest star in this
e-marketplace, namely the type of performance, price and location. As for the
alternatives tested as many as nine alternatives consisting of guest stars in the
Special Region of Yogyakarta area. The results of the functionality test based on
black box testing using chrome, mozilla, opera and Microsoft edge browsers state
that all validation functions and buttons on the e-marketplace can run according to
their functions. The implementation test results are in accordance with the
calculation of weighted product, namely the guest star that has the highest result of
the whole is Frengki Sermadi with a value of 0.135234, while the guest star that
has the lowest result of the whole is the Sanggar Titik Dua with a value of 0.083222.
