Abstract
From the material purchase recapitulation data, a lot of unused waste material during the implementation of mosque building construction projects in the Bintaro area, Tangerang City and Bekasi had a deviation of IDR 138,535,445 or 7.20% from the planned project cost budget. The planning consultant previously did not calculate the potential amount of unused material waste, nor was the implementing contractor able to allocate the remaining unused material during project implementation. The aim of this research is to look for the factors causing the remaining material and its influence on construction cost performance at the time construction project in progress. Using descriptive analysis with the SPSS program to obtain a regression equation from the questionnaire data of 40 respondents by asking 37 variable questions to directors, project managers, site managers, engineers and quality supervisors that are directly related to 4 building construction project site objects Mosque in the Bintaro area, Tangerang City. Data testing includes; Homogeneity test, validity and reliability test, descriptive analysis test, normality test, correlation test, factor test, and then multiple variable linear regression analysis was carried out. The results of the research showed 3 dominant factors that cause material waste in mosque building construction projects including 20 variables which were previously proposed, these 3 factors include material and human resource factors that can influence project cost performance targets by 4.3%, planning and material handling factors by 5.2% and documentation factors and work methods can influence project cost performance targets by 8.33% , the R Square price shows that these 3 material waste factors simultaneously influence the cost performance of warehouse building construction projects by 83.3%. Keywords : Cost performance, Material waste, Remaining Material,SPSS, Construction waste Dari data rekapitulasi pembelian material, banyak waste material yang tidak terpakai pada saat pelaksanaan proyek konstruksi bangunan Masjid di daerah Bintaro, Kota Tangerang dan Bekasi memiliki deviasi Rp138,535,445 atau sebesar 7,20 % dari rencana anggaran biaya proyek. Konsultan perencana sebelumnya tidak menghitung potensi besarnya waste material yang tidak terpakai begitu juga dengan kontraktor pelaksana tidak dapat mengalokasikan sisa material yang tidak terpakai selama pelaksanaan proyek berlangsung. Tujuan dari penelitian ini adalah mencari faktor – factor penyebab sisa material serta pengaruhnya terhadap kinerja biaya konstruksi pada saat proyek konstruksi berlangsung. Menggunakan analisis deskriptif dengan program bantu SPSS untuk mendapatkan persamaan regresi dari data kuesioner 40 responden dengan mengajukan 37 variabel pertanyaan kepada para direktur, proyek manajer, site manager, engineer, dan quality supervisor yang berhubungan langsung dengan 4 obyek lokasi proyek konstruksi bangunan Masjid di wilayah Bintaro,Kota Tangerang.Pengujian data meliputi; Uji homogenitas, Uji validitas dan reliabilitas, Uji analisis deskriptif, Uji normalitas, Uji korelasi, Uji faktor, dan selanjutnya dilakukan analisis regresi linier variabel berganda. Hasil penelitian menunjukkan 3 Faktor dominan yang menjadi penyebab waste material proyek konstruksi bangunan Masjid meliputi 20 variabel yang sebelumnya diajukan, 3 faktor tersebut diantaranya adalah faktor material dan SDM dapat mempengaruhi sasaran kinerja biaya proyek sebesar 4,3%, faktor perencanaan dan penanganan material sebesar 5,2% dan factor dokumentasi dan metode kerja dapat mempengaruhi sasaran kinerja biaya proyek sebesar 8,33%, harga R Square menunjukkan 3 faktor waste material tersebut berpengaruh secara simultan terhadap kinerja biaya proyek konstruksi bangunan gudang sebesar 83,3 %.
