ANALISIS PERBANDINGAN RISIKO BIAYA KONTRAK LUMPSUM DAN KONTRAK UNIT PRICE DENGAN METODE AHP (STUDI KASUS KONTRAKTOR DI KOTA DENPASAR)

Abstract

Two things that always emerge in business activity, including
construction business, are either earning profit or suffering risk of loss, directly or
indirectly. Many efforts have been done by contractors as the service provider, to
avoid or to mitigate risk in order to achieve the effective result. One of these is by
analyzing risk in terms of the type of project contract that is comparing between
Lumpsum contract and Unit Price contract from the contractor view.
The method used is Analytic Hierarchy Process (AHP). Analysis process initially
started from collecting the problems and making the hierarchy structure. The
hierarchy consists of three levels, that are objective (level I), criterion (level II), and
alternatif (level III). Based on the hierarchy then followed by composing a series of
questionnaires. Data was collected from questionnaires that were distributed to 20
respondents of contractors in Denpasar Regency. The data were then analyzed by
creating and comparing matrices, scaling priority weight of level II and III, and
checking the consistency as well.
The analysis result shows that priority value of lump sum contract is 81,70% and
the value of unit price contract is 18,30%. It means that lump sum contract has
higher risk of loss compare to unit price contract.
