Abstract

Material supply has a very important role in construction process. Material supply process require suitable and reliable supplier. In this study, fuzzy set theory is used as the appraisal and selection process of material suppliers to supply materials needed to produce concrete mix in a ready mix company. Sinusoidal, Blockley, and Baldwin models are used. This research uses three variables as qualifications, which are quality, performance, and payment. With these qualifications, ready mix concrete company can appraise material suppliers to be selected. It is shown that quality can be represented by Sinusoidal model, performance by Blockley model, and payment by Baldwin model, while the appropriate defuzzification method is maximum composite method.
Abstract in Bahasa Indonesia :
Aktivitas yang mempunyai peranan penting dalam proses pelaksanaan proyek konstruksi adalah penyediaan material. Proses penyediaan material memerlukan pemasok yang sesuai dan dapat diandalkan. Dalam studi ini dicoba untuk menggunakan teory fuzzy set dalam proses penelitian dan pemilihan pemasok material untuk adonan beton suatu perusahaan readymix concrete. Model yang dipergunakan adalah model Sinusoidal, Blockley dan Baldwin. Kualifikasi yang digunakan dipengaruhi oleh tiga variabel penentu yaitu variabel kualitas, performa dan pembayaran. Dengan kualifikasi tersebut perusahaan readymix concrete bisa menilai para supplier material yang akan dipakai perusahaan. Penelitian ini menunjukkan bahwa penilaian melalui variabel kualitas dapat diwakili oleh model Sinusoidal, untuk variabel performa diwakili oleh model Blockley dan variabel pembayaran diwakili oleh model Baldwin, sedangkan metode defuzifikasi yang sesuai adalah metode maksimum komposit.
