B50 at TBBM Padalarang: product update in the terminal automation system

B50 is diesel fuel (minyak solar) blended with 50 percent biodiesel made from palm oil. Kementerian ESDM made the blend mandatory through Keputusan Menteri ESDM No. 257.K/EK.01/MEM.E/2026 dated 17 June 2026, and the Directorate General of Oil and Gas set the B50 fuel specification in Keputusan Dirjen Migas No. 75.K/MG.06/DJM/2026, signed on 25 June and in force from 1 July 2026.
For a fuel terminal the change is not only in the tank. The terminal automation system has to know the new product, so every loading order, meter batch and delivery record carries the right material. That is the job Citia finished at Fuel Terminal Padalarang.

28 terminals still in transition from B40, per Kementerian ESDM.
What changed in the TAS
The update focused on the FD Flow application, the part of the Padalarang TAS that handles loading transactions. The product code changed from the B40 scheme to B50, which carries two risks: an operator picks the wrong product, or a transaction is recorded against the wrong material.
The terminal had a defined set of active materials, Biofame and Biosolar B50, as listed on the project page. The PSO and NPSO material codes were still pending, so they were deliberately left out of the operational configuration. The system had to handle only the active materials.
Reconfigure products
Products in FD Flow were reconfigured for the B50 scheme.
Update material codes
The Biofame and Biosolar B50 codes were added or updated.
Run test transactions
Test transactions used the new product codes.

Lessons from the update
The project page records four lessons that apply to any product change in a TAS: validate active material codes before the system update; never configure pending materials as operational products; run a test and document every product change; and follow the operational scheme in force at the terminal.
The Kepdirjen Migas decree adds a point for the receiving side: the biodiesel (B100) specification is the quality reference for accepting biofuel before it is blended with pure diesel (B0).

Common questions
What is B50 fuel in Indonesia?
B50 is diesel fuel blended with 50 percent palm-oil biodiesel. Kepmen ESDM No. 257.K/EK.01/MEM.E/2026 made the 50 percent blend mandatory.
When did B50 become mandatory?
From 1 July 2026, the date the B50 specification decree took effect. Kementerian ESDM launched the programme officially on 9 July 2026.
What has to change in a terminal automation system for B50?
The product and material codes used for loading transactions. At Padalarang that meant reconfiguring FD Flow, updating the active codes and running test transactions before use.
Why were the PSO and NPSO codes not configured?
They were still pending at the time of the update, and pending materials must not be set up as operational products.
