In 2011, Polii alongside Meiliana Jauhari was not able to win a title. Her best results at the Super Series event was the semi-finals in the India Open; she was also a quarter-finalist in Singapore and Indonesia Open. In the second round of the Indonesia Open, a Super Series Premier event, Polii received a yellow card from the umpire, for taking too much time during a close match against Ma Jin and Pan Pan. At the Grand Prix event, she was a finalist in the Chinese Taipei Open; semi-finalist in Malaysia and Swiss Open. Together with Jauhari, she competed at the World Championships in London. The duo lost in the quarter-finals to Miyuki Maeda and Satoko Suetsuna, worsening their head-to-head record against that pair to 0–4. Polii was part of the national team that won the bronze medal at the Sudirman Cup, where Indonesia lost in the semi-finals to Denmark by a score of 1–3.
