The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "The name Whoosh is inspired by the sound of a fast train whizzing by at high speed. Whoosh itself also has an acronym for important values within it. 'This is inspired by the sound of a high-speed train (Whoosh High-Speed Train) and the abbreviation for Whoosh stands for Time Saving, Optimal Operation, Great System. Once again, w h o o s h, pronounced whoosh,' said Jokowi."

The government itself plans to extend its route to Surabaya, East Java. However, experts suggest that the government evaluate the performance of KCJB first before deciding to extend the route. Jokowi said that the plan to extend the route to Surabaya is currently in the study phase. Minister of Transportation Budi Karya Sumadi revealed that there is a tendency for the chosen route to pass through the southern part of Java.

However, environmental activists say that if possible, the KCJB route should not be extended to Surabaya because of the high cost and environmental impact. The reason is because the construction funds have swelled, which could lead Indonesia into a "debt trap with China," according to some observers. This high-speed train project has also sparked environmental issues, including flooding in Bekasi and West Bandung.
