Busy making infrastructure development inside the country. Not having enough capacity and financing like China construction companies have.
The one who will likely build the bridge is Hutama Karya, one of SOE big constructors that is currently building Trans Sumatra Highway. They are the only company so far that has already shown the interest and has offered the proposal on the tender.

Trans-Sumatra Toll Road is an under-construction
tolled expressway stretching across
Sumatra Island in Indonesia from the northern tip of
Banda Aceh to the southern tip of
Bakauheni. This toll road was originally planned to connect to the established toll road system of
Java through the now cancelled
Sunda Strait Bridge.
[1] The toll road is to include supporting corridors connecting the cities of
Padang,
[2] Bengkulu,
[3] and
Sibolga[4] on the western coast of the island to the main corridors stretching across the more populated eastern coast. State construction company Hutama Karya
[a] has been given a
government-granted monopoly to operate the network.
The toll's entire length of 2,818 km (1,751 mi)
[5] will cost an estimated Rp476 trillion (US$33.2 billion)
[6][7] and consist of seventeen main segments and seven supporting segments.
[5] The toll road is expected to be completed by 2024. As of October 2022, 1,074 km (667 mi) of the road were completed and operational.

Basically they are already conglomeration and can build cheaper due to having many subsidiary companies making many construction parts.
Some of our SOE has made many projects overseas that include project to enlarge Masjidil Haram, LRT project in Taiwan, and also rail project between Laos and Vietnam.
This 7 kilometer long bridge will likely be financed by foreign bank in China that I think would not force us to use China construction companies or materials.
