Pekerjaan perbaikan ruas jalan memerlukan penggunaan alat berat yang memiliki produktivitas optimal agar pelaksanaan proyek dapat berlangsung secara efektif, efisien, dan sesuai dengan target waktu yang telah ditetapkan. Produktivitas alat berat dipengaruhi oleh berbagai faktor, seperti waktu siklus kerja, kondisi lapangan, efisiensi operator, serta karakteristik material yang digunakan. Penelitian ini bertujuan untuk menganalisis produktivitas Dump Truck, Motor Grader, dan Vibro Roller pada pekerjaan perbaikan ruas Jalan Simpang Tujuh–Simpang Lamreung, Kabupaten Aceh Besar, serta membandingkan produktivitas aktual dengan produktivitas berdasarkan Analisis Harga Satuan Pekerjaan (AHSP) Kementerian Pekerjaan Umum dan Perumahan Rakyat (PUPR). Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi lapangan (field study). Pengumpulan data dilakukan melalui metode time study, yaitu dengan mengamati dan mencatat waktu siklus (cycle time) masing-masing alat berat yang meliputi waktu pemuatan (loading), pengangkutan (hauling), pembongkaran (dumping), perjalanan kembali (return), serta waktu operasi Motor Grader dan Vibro Roller selama pekerjaan berlangsung. Pengamatan dilaksanakan pada segmen STA 0+358 sampai STA 0+558,04 selama 10 hari kerja efektif. Data hasil pengamatan kemudian dianalisis untuk memperoleh produktivitas aktual dan dibandingkan dengan produktivitas teoritis berdasarkan AHSP. Hasil penelitian menunjukkan bahwa produktivitas aktual Dump Truck sebesar 37,17 m³/jam, Motor Grader sebesar 2.822 m²/jam, dan Vibro Roller sebesar 1.326 m²/jam. Sementara itu, produktivitas berdasarkan AHSP masing-masing sebesar 40,50 m³/jam, 3.000 m²/jam, dan 1.450 m²/jam. Hasil perbandingan menunjukkan bahwa produktivitas aktual ketiga alat berat masih berada di bawah produktivitas teoritis dengan selisih berturut-turut sebesar 8,22%, 5,93%, dan 8,55%. Perbedaan tersebut dipengaruhi oleh waktu siklus kerja, jarak angkut material, kondisi permukaan jalan, jumlah lintasan, kondisi material Base B, serta efisiensi kerja alat dan operator. Secara keseluruhan, penggunaan alat berat pada pekerjaan perbaikan ruas Jalan Simpang Tujuh–Simpang Lamreung dapat dikategorikan cukup efektif, meskipun masih terdapat peluang peningkatan produktivitas melalui pengelolaan waktu kerja dan koordinasi antaralat yang lebih optimal.

Road repair projects require the use of heavy equipment with optimal productivity to ensure the project proceeds effectively, efficiently, and meets established time targets. Heavy equipment productivity is influenced by various factors, such as work cycle time, site conditions, operator efficiency, and the characteristics of the materials used. This study aims to analyze the productivity of dump trucks, motor graders, and vibro rollers during the repair of the Simpang Tujuh–Simpang Lamreung road section in Aceh Besar Regency, and to compare actual productivity with the productivity standards set by the Ministry of Public Works and Public Housing (PUPR) in the Unit Price Analysis (AHSP). A quantitative descriptive method using a field study approach was employed. Data collection was conducted via time studies, involving the observation and recording of cycle times for each piece of equipment—including loading, hauling, dumping, and return times—as well as the operating times for motor graders and vibro rollers during the work. Observations were carried out on the segment between stationing (STA) 0+358 and STA 0+558.04 over a period of 10 effective working days. The observational data were analyzed to determine actual productivity and compared with theoretical productivity based on AHSP standards. The results indicate that the actual productivity was 37.17 m³/hour for dump trucks, 2,822 m²/hour for motor graders, and 1,326 m²/hour for vibro rollers. Meanwhile, the AHSP-based productivity figures were 40.50 m³/hour, 3,000 m²/hour, and 1,450 m²/hour, respectively. The comparison reveals that the actual productivity of all three types of equipment remained below the theoretical productivity, with respective variances of 8.22%, 5.93%, and 8.55%. These differences are influenced by work cycle times, material haul distances, road surface conditions, the number of passes, the condition of the Base B material, and the operational efficiency of both the equipment and the operators. Overall, the use of heavy equipment for the repair of the Simpang Tujuh–Simpang Lamreung road section can be considered reasonably effective, although there remains scope to enhance productivity through better management of working time and more optimal coordination between equipment units.
