Dejan Ferdinansyah

Ferdinansyah began training professionally in primary school under Bintang Badminton Club in Bogor.^[2] When the club dissolved following the owner's passing, he briefly joined PB Exist in Jakarta, but was released in 2018 as the club wanted to focus on junior players.^[2] Luckily, PB Djarum offered him a place in 2019.^[1] Paired with Serena Kani, he reached the final of the South Australia International.^[3] They also played at the 2020 Thailand Masters^[4] and the 2021 Spain Masters^[5]. Ferdinansyah and Kani became the sole Indonesian representative at the 2021 BWF World Championships after the Indonesian Badminton Federation withdrew all the national team players from the tournament.^[6]

Ferdinansyah was selected to pair former national team player Gloria Emanuelle Widjaja following her return to PB Djarum.^[7] Making their debut at the All England Open, they lost to eventual winners Yuta Watanabe and Arisa Higashino in the second round.^[8] They also struggled at the Swiss Open^[9] and the Thailand Open.^[10]

Their performance began to pick up pace at the second half of the year, which saw them winning titles at the Denmark Masters,^[11] the Yogyakarta Indonesia International Series,^[12] the Vietnam Open, where they won over compatriots Rehan Naufal Kusharjanto/Lisa Ayu Kusumawati^[13], and the Indonesia International Challenge in Malang.^[14] Although Jiang Zhenbang and Wei Yaxin put the pair's win streak to a pause at the Indonesia Masters Super 100,^[15] by this time, they had broken into the top 50.^[16] They also reached the semifinals of the Australian Open.^[17] Ferdinansyah and Widjaja closed off 2022 with a world rank of no. 20.^[18]

Ferdinansyah and Widjaja saw mixed results at the start of the year, starting with a semifinal at the Malaysia Open^[19] followed by a second-round loss at the India Open^[20] and quarterfinal finishes at the Indonesia Masters and the Thailand Masters.^[21][22] Nevertheless, those were enough to bolster their rank to 15th at the end of January 2023.^[23]

Their run in Europe proved to be challenging, with early exits at the German Open,^[24] All England Open,^[25] and the Swiss Open.^[26] Surprisingly, they obtained a bronze medal at the Asian Championships in Dubai, notably defeating sixth seeds Feng Yanzhe and Huang Dongping at the first round.^[27]

Following their rising performance, Ferdinansyah and Widjaja was called up for the 2023 Sudirman Cup in Suzhou, China. The pair were only fielded once against Dechapol Puavaranukroh and Sapsiree Taerattanachai of Thailand and were unable to contribute points to the tie.^[28]

Their slump continued throughout the Malaysia Masters,^[29] Singapore Open,^[30] Indonesia Open,^[31] Korea Open,^[32] Japan Open,^[33] and Australian Open,^[34] as well at the World Championships.^[35] Fortunately, they bounced back as runner-ups at the Kaohsiung Masters.^[36] They closed off the year with a hard-fought first World Tour title at the Syed Modi International.^[37]

Ferdinansyah and Widjaja reached the quarterfinals of the Thailand Masters,^[38] All England Open,^[39] Thailand Open,^[40] Malaysia Masters,^[41] and at the Indonesia Open.^[42] However, their semifinal finish at the China Open^[43] pulled them up to a world rank of no. 11, which was Ferdinansyah's career high.^[44] They later reached consecutive finals at the Macau Open^[45] and the Korea Masters.^[46] Despite failing to qualify for the 2024 Paris Olympics, they were able to qualify for the World Tour Finals, marking Ferdinansyah's first appearance at the year-end tournament.^[47] They finished third in Group B with two losses and one win.^[48]

Ferdinansyah concluded his partnership with Widjaja at the Malaysia Open to move into the national team.^[49] He commenced his new journey in a highly expected partnership with Siti Fadia Silva Ramadhanti.^[50] They started out at the India Open, where they lost to Jiang Zhenbang/Wei Yaxin at the second round.^[51] Later, they became runner-ups at the Thailand Masters to home pair Dechapol Puavaranukroh/Supissara Paewsampran.^[52] Ferdinansyah played with Ramadhanti at the Asia Mixed Team Championships and earned a gold medal with the team despite being absent in the final due to a knee injury.^[53] He was called up to his second Sudirman Cup but only played against Korea's Seo Seung-jae/Chae Yu-jung.^[54] After that, he finished second at the Taipei Open to juniors Jafar Hidayatullah/Felisha Pasaribu.^[55]

With Ramadhanti returning to women's doubles, Ferdinansyah was paired with new recruit Bernadine Wardana.^[56] In their first four months, they snatched titles at the Al Ain Masters and the Syed Modi International Super 300^[57][58], as well as becoming runner-ups at the Malaysia Masters Super 100 and the Odisha Masters.^[59][60]
