Erzaldi Rosman Djohan

On 12 May 2017, Djohan was sworn in as governor. Months after his inauguration, Djohan declared a moratorium on issuing new tin mining licenses in the province, intended to tackle illegal mining on the island and allow the provincial government to develop new regulations on ecologically friendly mining practices. He noted his intentions in an interview with Jakarta Globe to move away from tin mining, and develop tourism and metallurgical industries such as thorium extraction.

Djohan declared his candidacy for the governorship of the province in August 2016. By then, he had moved to Gerindra, and became the chairman of its provincial branch. In the following 2017 gubernatorial election, Djohan won 38.9% (213,442) of votes in a four-way election, defeating incumbent governor Rustam Effendi.

Before entering politics, Djohan worked at several companies, including a property company between 1999 and 2005. In 2004, he was elected to Bangka-Belitung's Regional People's Representative Council (DPRD) as part of Golkar, though he only held the seat until 2005 when he was elected as Central Bangka's vice-regent. In 2010, he was elected regent, and was elected for his second term in 2015 with 57.1% of votes. His first term expired on 24 September 2015, before he was sworn in for a second term on 17 February 2016.
