ABSTRACT
THE CORRELATION BETWEEN TIME AND COST IN THE PERFORMANCE
OF BUILDING CONSTRUCTION MANAGEMENT
By:
Jilawi Ramadan Mohamed Jilawi
S941302037
Building construction is one of business that always show development
because the number of people who need construction are increase. Unfortunately, this
business often has problem especially on the success of building construction. Two
problems that can influence the success of building construction are cost and time
because those variables are relate each other. Therefore, this research will identify
and analyze the correlation between time, cost and building construction.
This research was conducted with descriptive quantitative. This research used
survey to 41 customers by questioonaire. Then, the answer of questionnaire was
analyzed with SPSS and compare it to interview result.
Based on the questionnaire result, it was obtained that cost has 0,434
influence to building construction. It means that cost has middle influence on
building construction. While time has 0.386 influence on building construction.
Therefore, it can be concluded that cost gave higher impact on building construction
than time because cost is correlate with quality of material, labor, heavy equipment
and administration fee.

Konstruksi bangunan adalah salah satu bisnis yang selalu menunjukkan
pembangunan karena jumlah orang yang membutuhkan konstruksi meningkat.
Sayangnya, usaha ini sering memiliki masalah terutama pada keberhasilan konstruksi
bangunan. Dua masalah yang dapat mempengaruhi keberhasilan konstruksi bangunan
adalah biaya dan waktu karena variabel ini berhubungan satu sama lain. Oleh karena
itu, penelitian ini akan mengidentifikasi dan menganalisis hubungan antara waktu,
biaya dan konstruksi bangunan.
Penelitian ini dilakukan dengan deskriptif kuantitatif. Penelitian ini
menggunakan survei untuk 41 pelanggan dengan kuesioner. Kemudian, jawaban dari
kuesioner dianalisis dengan SPSS dan dibandingkan dengan hasil wawancara.
Berdasarkan hasil kuesioner, diperoleh bahwa biaya memiliki 0.434
mempengaruhi kinerja manajemen konstruksi bangunan. Ini berarti bahwa biaya
mempunyai pengarh yang cukup pada kinerja manajemen konstruksi bangunan.
Sementara, waktu memiliki 0.386 pengaruh pada kinerja manajemen konstruksi
bangunan. Oleh karena itu, dapat disimpulkan bahwa biaya memberi dampak yang
lebih tinggi pada kinerja manajemen konstruksi bangunan daripada waktu karena
biaya berkorelasi dengan kualitas material, tenaga kerja, alat berat dan biaya
administrasi.
