Analisis Produktivitas dan Biaya Operasional Alat Berat Tower Crane (Studi Kasus Proyek Pembangunan Kampus UIN Maulana Malik Ibrahim Malang Tahap 2)

Productivity and Operational Cost Analysis of Tower Crane Equipment (Case Study on the UIN Maulana Malik Ibrahim Malang Campus Development Project Phase 2)

Peningkatan kebutuhan fasilitas pendidikan akibat pertumbuhan penduduk mendorong percepatan pembangunan gedung bertingkat, termasuk kampus di Kota Malang. Dalam konstruksi gedung, penggunaan alat berat seperti tower crane sangat krusial untuk efisiensi dan efektivitas pekerjaan. Penelitian ini bertujuan menganalisis produktivitas dan biaya operasional tower crane pada Proyek Pembangunan Kampus UIN Maulana Malik Ibrahim Malang Tahap 2 dengan pendekatan deskriptif kuantitatif. Data dikumpulkan melalui observasi dan wawancara di lapangan, meliputi volume material, waktu siklus, biaya operasional, serta spesifikasi alat dan material. Hasil penelitian menunjukkan bahwa produktivitas rata-rata tower crane QLCM-Q7030 selama 20 hari pengamatan secara teoritis sebesar 9158,04 kg/jam, sedangkan hasil aktual di lapangan 6954,41 kg/jam. Perbedaan ini disebabkan oleh jenis material yang diangkut, kondisi lapangan proyek,  kondisi alat, kemampuan operator, serta manajemen proyek yang memengaruhi koordinasi dan pengaturan kerja. Biaya operasional secara teoritis tercatat sebesar Rp569.013,86 per jam, sedangkan data aktual menunjukkan Rp575.270,66 per jam.

Kata kunci: Tower crane, produktivitas, biaya operasional.

The increasing demand for educational facilities due to population growth has accelerated the construction of multi-story buildings, including university campuses, particularly in Malang City. In high-rise building construction, the use of heavy equipment such as tower cranes is crucial to support work efficiency and effectiveness. This study aims to analyze the productivity and operational costs of tower crane usage in the UIN Maulana Malik Ibrahim Malang Campus Development Project Phase 2 using a descriptive quantitative approach. Data were collected through field observations and interviews, covering material volume, cycle time, operational costs, and specifications of materials and the tower crane. The results show that the theoretical average productivity of the QLCM-Q7030 tower crane over 20 days of observation was 9,158.04 kg/hour, while the actual productivity in the field was 6,954.41 kg/hour. This discrepancy is caused by several factors: the type of materials lifted, site conditions, equipment condition, operator skill, and project management, which affects coordination and workflow. The theoretical operational cost was IDR 569,013.86 per hour, while the actual cost recorded was IDR 575,270.66 per hour.

Keywords: Tower crane, productivity, operational cost.
