Reducing Maintenance Cost of Concrete Structure Jetty, Piping & Fuel Tank using Mambo3 (Material Admixture Bamboo Fiber with Honeycomb Configuration MOR 3) at Fuel Terminal Tanjung Gerem

Abstract

PT Pertamina Patra Niaga West Java Region is an investment implementation function based on the budget written in RKAP of each period. The investments carried out are spread in each work location at Jakarta, Banten and West Java. Fuel Terminal Tanjung Gerem is one of the Main Transit Fuel Terminals in the Pertamina Patra Niaga – West Java Region. Located near seafront made Fuel Terminal Tanjung Gerem have high corrotion rate more than 0,05 mm/year. Based on the pareto diagram analysis, the main cause for the high operating cost budget year 2021 of Fuel Terminal Tanjung Gerem was the High Maintenance Cost of Concrete Structure of Jetty, Fuel Tank and Piping due to high corrotion rate. Maintenance cost especially for retrofit activity usually use common fiber reinforced polymer. The weakness of common fiber reinforced polymer cannot strengthen the structural strength of existing facilities.  To overcome this problem, Mamboo3 (Material Admixture Bamboo Fiber with Honeycomb Configuration MOR 3) is determined as alternative solution of Common Fiber Reinforced Polymer.  By applying Mambo3, the Quality of Structure (Concrete and Metal) after retrofit have Tensile strength min 564 Mpa and yield strength min 734 Mpa (better than quality of new facilities). In addition lifetime of existing facilities increased to 8 years and reducing maintenance cost 30,2% (USD 51,77 / m2). This innovation has been endorsed by an external party, PT Surveyor Indonesia, PT. Sucofindo and Institut Teknologi Bandung. Replication has been carried out for the Fuel Terminal PT. Pertamina Patra Niaga – West Java Region and Central Java Region.
