Abstract

Pekerjaan lifting chimney pada proyek Waste Heat Boiler (WHB) memerlukan perencanaan yang aman dan efisien karena memiliki risiko operasi yang tinggi. Pada kondisi aktual, pengangkatan dilakukan menggunakan crane 130 ton untuk mengangkat beban maksimum sekitar 8,7 ton, sehingga terdapat indikasi penggunaan crane yang kurang optimal. Penelitian ini bertujuan menentukan kapasitas crane yang paling optimal melalui analisis variasi crane 85 ton, 90 ton, 95 ton, 100 ton, 110 ton, 120 ton, dan 130 ton. Evaluasi dilakukan berdasarkan perhitungan utilisasi sesuai standar EN 13000, analisis stabilitas, ground bearing pressure (GBP), serta metode weighted scoring dengan kriteria safety, technical capability, operational flexibility, dan economy. Hasil penelitian menunjukkan bahwa crane 95 ton merupakan alternatif terbaik dengan nilai weighted score sebesar 4, lebih tinggi dibandingkan crane aktual 130 ton yang memperoleh skor 3,8. Crane 95 ton mampu memenuhi persyaratan teknis dan keselamatan dengan tingkat utilisasi yang lebih optimal serta efisiensi penggunaan kapasitas yang lebih baik.

Chimney lifting operations in a Waste Heat Boiler (WHB) project require careful planning due to their high operational risk. In the actual project, a 130-ton crane was used to lift a maximum load of approximately 8.7 tons, indicating potential inefficiency in crane capacity utilization. This study aims to determine the most optimal crane capacity by evaluating 85-ton, 90-ton, 95-ton, 100-ton, 110-ton, 120-ton, and 130-ton crane alternatives. The analysis was conducted based on crane utilization in accordance with EN 13000, stability analysis, Ground Bearing Pressure (GBP), and a weighted scoring method using the criteria of safety, technical capability, operational flexibility, and economy. The results show that the 95-ton crane achieved the highest weighted score of 4.0, outperforming the actual 130-ton crane, which obtained a score of 3.8. The 95-ton crane satisfied all technical and safety requirements while providing more optimal utilization and better capacity efficiency. These findings indicate that crane selection should not be based solely on nominal lifting capacity but should also consider safety, technical performance, operational flexibility, and economic efficiency.
