Innovation of Spun Pile Manufacturing Method in Indonesia Using a Risk Approach and ISO 56002 Innovation Process to Increase Competitiveness

As of market for precast is thriving, some activities still need to be carried out optimally and efficiently for precast concrete products by taking into account competitors locally and abroad to encourage continuous improvement necessity of productivity performance in increasing the competitiveness of companies. Thus, developing innovative methods for making precast concrete products is necessary. Focuses on a product with the highest production capacity in Indonesia, precast concrete with the rotary method spun pile. The paper aims to explore Indonesia's current precast concrete production process activities, identify risk factors, and find high risk as the basis of innovation of spun pile manufacturingmethods. This goal was achieved using qualitative research, combining and validating the results from experts on production process activities and risk factors, which were analyzed using the Delphi method and ISO 56002. The findingsof this study are focused on the dominant risk, honeycomb concrete, from the spinning process activity. This study resulted in an innovation process of high-volume fly ash cementitious mixtures for cement grout injection on honeycomb concreteand additional preventive activities on spun pile workflow, generated from 66 risk factors to increase a company's competitiveness in facing market competition.
