What Caused Indonesia to Stop in the Sudirman Cup Semifinals?

1. What factors caused Indonesia to lose to South Korea?

The pair Dejan Ferdinansyah/Siti Fadia Silva Ramadhanti (mixed doubles) suffered a significant defeat against Seo Seung-jae/Chae Yu-jung with scores of 10-21 and 15-21. This loss becomes a mental burden for Indonesia, as the mixed doubles were expected to contribute points. Dejan and Fadia are a new pair who do not have much experience playing together. Additionally, Dejan was only fielded in the semifinals, which limited his experience of the match atmosphere. However, there were no other options.

Putri Kusuma Wardani in the women's singles was unable to stop An Se-young, the world number one player, and Putri lost in two straight games (18-21, 12-21).

Meanwhile, in the women's doubles, Amalia Cahaya Pratiwi/Siti Fadia Silva Ramadhanti put up a fierce fight, forcing the match to three games, but ultimately lost to Lee So-hee/Back Ha-na (10-21, 21-18, 15-21). Fadia, who competed in two events, may have experienced fatigue, which affected her performance.

According to Tiwi, in the first game they were too focused on the opponent's slow play. The opponent was also very consistent and difficult to break through defensively. In the second game, they were able to play better and forced a rubber game. In the deciding game, physical condition, technique, and mental strength were tested.

Indonesia continues to showcase impressive achievements in both men's singles and doubles events. Alwi Farhan defeated Cho Geon-yeop (16-21, 21-8, 21-8). Muhammad Shohibul Fikri/Bagas Maulana won a thrilling match against Seo Seung-jae/Kim Won-ho (21-18, 13-21, 25-23). The victory of Fikri/Bagas briefly reignited hope; however, the immense pressure in the women's doubles as the decisive match proved too much for Amalia/Fadia to bear.

2. How does Indonesia's strength compare to South Korea's?

The top four rankings reflect a realistic depiction of Indonesia's strength at present. Throughout the year 2025, Indonesian players have not frequently ascended the podium in BWF World Tour tournaments. Out of the eight Super 300, 500, 750, and 1000 tournaments that have taken place in 2025, Indonesian players have only secured one championship title, which was achieved by the women's doubles team of Siti Fadia Silva Ramadhanti/Lanny Tria Mayasari at the Thailand Masters Super 300 tournament.

Indonesia is losing the competition against South Korean players who have already collected 11 championship titles, four of which are from high-level tournaments, namely the Malaysia Open and All England Super 1000. China has secured eight championship titles, while Japan and Thailand have five titles each, and Denmark has three championship titles.

The Sudirman Cup reflects the strength of each country across all events. Indonesia's weaknesses were evident after losing in the mixed doubles, women's singles, and women's doubles events.

In the world rankings, South Korea actually only has women's singles and doubles players in the top 10. However, South Korea has strong men's and mixed doubles players who can perform at their best even when their partners are changed. The only weakness of South Korea lies in the men's singles sector.

3. What is the meaning of Indonesia's appearance in the 2025 Sudirman Cup semifinals?

Indonesia has waited for six years to once again experience the atmosphere of the Sudirman Cup semifinals since Nanning, China in 2019. Previously, Indonesia consistently reached the semifinals from 1989 to 2011, but the country's journey became unstable starting in 2013.

From 2013 to 2023, Indonesian athletes have been stopped by opponents three times in the quarter-finals and twice in the semi-finals. The worst record was in Gold Coast 2017 when the Red and White was eliminated in the group stage for the first time.

China, Japan, and South Korea are the teams that reached the top four in the Sudirman Cup Vantaa 2021 and Suzhou 2023. Japan has advanced to the semifinals six consecutive times, while China has never missed competing in the top four since the Sudirman Cup was first held in Jakarta in 1989. For Indonesia, the semifinal on Saturday (3/5/2025) marks the first time after being eliminated in the quarterfinals in 2021 and 2023.

Indonesia advanced to the semifinals after defeating Thailand, 3-1, in the quarterfinals on Friday (2/5/2025). This victory avenged the defeat from two years prior.

Since the Sudirman Cup in 1989 until 2005, Thailand was only able to compete in Group II or III, meaning two tiers below China, South Korea, Denmark, including Indonesia. After the format of the Sudirman Cup changed in 2021, the tournament was only participated in by the 16 best teams from various federations. However, by that time, Thailand had already made significant progress.

Thailand successfully reached the semifinals in 2013, 2017, and 2019. Thailand performed better than Indonesia, which was eliminated in the quarterfinals in 2013 and the group stage in 2017. Thailand defeated Indonesia 3-2 in the group stage of 2023, after Indonesia won decisively 5-0 in their first meeting in 1995.
