Penelitian ini bertujuan untuk menganalisis produktivitas tenaga kerja dan alat berat Tower Crane pada proyek pembangunan Office Tower 12 Lantai PIK 2 dengan mengukur durasi pekerjaan pembesian, bekisting, dan pengecoran kolom. Data diperoleh melalui pengamatan langsung di lapangan dan pengumpulan informasi serta perhitungan terkait volume pekerjaan serta durasi waktu. Hasil analisis menunjukkan bahwa volume pekerjaan pembesian, bekisting, dan pengecoran adalah konsisten di setiap titik pengamatan, masing – masing dengan 1075,1 kg, 7,92 m², dan 1,143 m³. Durasi pekerjaan tenaga kerja untuk pembesian berkisar antara 5,5 hingga 6,4 jam, sementara bekisting dan pengecoran menunjukkan variasi antara 0,67 m²/jam hingga 0,97 m²/jam dan 0,09 m³/jam hingga 0,12 m³/jam, sedangkan pada nilai produktivitas pembesian, bekisting, dan pengecoran berturut - turut antara 167,54 kg/jam hingga 196,56 kg/jam, 8,64 m²/jam hingga 12,51 m²/jam, 10,77 m²/jam hingga 12,94 m²/jam. Temuan ini menunjukkan bahwa efisiensi operasional alat berat dan tenaga kerja dapat mempengaruhi produktivitas keseluruhan proyek. Saran diberikan untuk meningkatkan akurasi pengumpulan data serta mempertimbangkan faktor eksternal yang mempengaruhi produktivitas.

Workers and heavy equipment productivity play a crucial role in the success of construction projects, particularly in the structural column work of high-rise buildings. This study aims to analyze the productivity of workers and Tower Crane on the Office Tower 12 Lantai PIK 2 construction project by measuring the duration of rebar work, formwork, and column concrete pouring. Data were obtained through direct field observations, along with the collection and calculation of work volume and time duration. The analysis results show that the volume of rebar, formwork, and concrete pouring work is consistent at each observation point, with values of 1075.1 kg, 7.92 m², and 1.143 m³, respectively. Workers duration for rebar work ranges from 5.5 to 6.4 hours, while formwork and concrete pouring show variations from 0.67 m²/hour to 0.97 m²/hour and 0.09 m³/hour to 0.12 m³/hour, respectively. Productivity values for rebar, formwork, and concrete pouring are between 167.54 kg/hour to 196.56 kg/hour, 8.64 m²/hour to 12.51 m²/hour, and 10.77 m³/hour to 12.94 m³/hour. These findings indicate that the operational efficiency of equipment and workers can significantly impact the overall productivity of the project. Recommendations are provided to enhance data collection accuracy and consider external factors affecting productivity.
