Abstract
Pekerjaan konstruksi jalan tol, khususnya pada Proyek Jalan Tol Solo-Yogyakarta-NYIA Kulon Progo Seksi 1 Paket 1.2: Klaten-Purwomartani (STA 39+300 s.d. STA 41+600), mencakup salah satu tahap penting yaitu pekerjaan tanah. Pekerjaan ini meliputi galian dan timbunan Common Borrow Material (CBM) yang sangat bergantung pada penggunaan alat berat seperti bulldozer, excavator, dump truck, vibro roller, dan sheep foot roller. Permasalahan yang sering muncul di lapangan adalah pemilihan jenis dan jumlah alat berat yang kurang tepat terhadap kondisi eksisting, sehingga menimbulkan keterlambatan, pemborosan biaya operasional, dan jadwal pelaksanaan yang tidak efisien. Penelitian ini bertujuan menentukan kombinasi alat berat yang optimal untuk memperoleh biaya dan waktu pekerjaan minimum. Data primer dikumpulkan melalui observasi lapangan, kemudian dianalisis dengan penyusunan Work Breakdown Structure (WBS). Selanjutnya dilakukan perhitungan volume pekerjaan tanah, produktivitas alat, biaya operasional, serta penyusunan jadwal pelaksanaan menggunakan bantuan perangkat lunak untuk penjadwalan. Hasil perhitungan menunjukkan total volume pekerjaan galian sebesar 46.470,10 m³ dan timbunan sebesar 544.865,00 m³. Berdasarkan hasil analisis membandingkan 3 kombinasi, Kombinasi B dengan menggunakan excavator, dump truck, motor grader, vibro roller, dan sheep foot roller terpilih sebagai alternatif paling optimal. Kombinasi B menghasilkan total biaya sebesar Rp 90.190.707.628,53 dengan durasi pelaksanaan 209 hari. Analisis biaya terjadi efisiensi anggaran senilai Rp 7.801.466.378,01, menurunkan total pembiayaan dari Rp 97.992.174.006,54 ke Rp 90.190.707.628,53 dan percepatan waktu sebanyak 104 hari dari 313 hari ke 209 hari. Efisiensi ini dicapai karena penggunaan motor grader yang lebih presisi dan cepat dalam perataan tanah, sehingga mengurangi beban kerja alat pemadat.

Toll road construction projects, particularly the Solo–Yogyakarta–NYIA Kulon Progo Toll Road Project Section 1 Package 1.2: Klaten–Purwomartani (STA 39+300 to STA 41+600), involve one of the most critical stages, namely earthwork operations. These activities include excavation and embankment using Common Borrow Material (CBM), which heavily rely on heavy equipment such as bulldozers, excavators, dump trucks, vibro rollers, and sheep foot rollers. A common problem encountered in the field is the improper selection of the type and number of heavy equipment in relation to existing site conditions, leading to project delays, increased operational costs, and inefficient scheduling. This study aims to determine the optimal combination of heavy equipment to achieve minimum cost and time for earthwork operations. Primary data were collected through field observations and analyzed by developing a Work Breakdown Structure (WBS). Furthermore, calculations were conducted for earthwork volumes, equipment productivity, operational costs, and project scheduling using scheduling software. The results show that the total excavation volume is 46,470.10 m³, while the embankment volume reaches 544,865.00 m³. Based on a comparative analysis of three equipment combinations, Combination B utilizing an excavator, dump truck, motor grader, vibro roller, and sheep foot roller was selected as the most optimal alternative. Combination B resulted in a total cost of IDR 90,190,707,628.53 with a project duration of 209 days. The cost analysis indicates a budget efficiency of IDR 7,801,466,378.01, reducing the total project cost from IDR 97,992,174,006.54 to IDR 90,190,707,628.53, along with a time acceleration of 104 days from 313 days to 209 days. This efficiency was achieved due to the use of a motor grader, which provides more precise and faster land leveling, thereby reducing the workload of compaction equipment.
