ABSTRACT
THE CORRELATION BETWEEN TIME AND COST IN THE PERF ORMANCE 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.

ABSTRAK
HUBUNGAN ANTARA WAKTU DAN BIAYA PADA KINERJA MANAJEMEN KONSTRUKSI BANGUNAN
Oleh:
Jilawi Ramadan Mohamed Jilawi S941302037
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.
Kata kunci: Waktu, Biaya, Kinerja Manajemen Konstruksi bangunan
