Luluk Hadiyanto (born 8 June 1979) is a badminton player from Indonesia, specialized in men's doubles and former world number one with doubles partner Alvent Yulianto. Early years "Lulu" as he is fondly called, was a member of badminton club PB Djarum. He was born in the small village of Pengkolrejo, in the district of Japah, Blora, Central Java. He was the first son of three siblings of the couple Edi Sunarto and Sulami, his parents both educators at an elementary school. His father encouraged both his sports career in Jakarta and his educational development in Solo. In 1999 he was finally accepted in the National Squad at the Pelatnas Cipayung. Career His first big international success came in 2001 winning the Thailand Open with Sigit Budiarto. In partnership with fellow countryman Alvent Yulianto, Hadiyanto won four top tier international men's doubles titles in 2004; the Thailand, Korea, Singapore, and Indonesia Opens. They achieved a number one world ranking that year despite a disappointing 2004 Olympics which saw them eliminated in the round of 16. Since 2004 Hadiyanto and Yulianto have struggled to achieve top form. Second place finishes in the quadrennial Asian Games (2006); and the Japan (2007) and Korea (2008) Opens (now called Super Series events) have been their highest finishes in major international tournaments, though they won the Indonesian national title in 2007. In 2006 they also won a bronze medal at the Asian Badminton Championships in Johor Bahru, Malaysia. After a disappointing 21-19, 14-21, 14-21, first round loss against the Japanese Keita Masuda & Tadashi Ohtsuka at the 2008 Olympics with Alvent Yulianto, the couple split partnership and Luluk left the National team of Indonesia. From 2009 Luluk Hadiyanto as an independent then first partnered Candra Wijaya and then more frequently Joko Riyadi. Still in men's doubles Luluk Hadiyanto won his last big event, the 2009 Vietnam Open with new partner Joko Riyadi, seeded 7th beating 1st seeded Malaysian doubles pair Choong Tan Fook & Lee Wan Wah 21-17, 22-20 in the semi-finals and then another Malaysian couple Hoon Thien How & Ong Soon Hock in the final of this BWF Grand Prix event in straight games 21-19, 22-20. In 2010 Luluk Hadiyanto again formed a doubles combination with Candra Wijaya. In the middle of 2011 Luluk changed partnership one last time prior to retirement, he coupled up with fellow Indonesian Imam Sodikin Irawan. Achievements World
