He and his five siblings were the children of an army captain and his wife Indriana Kartika, an employee of the Department of Information; three of his siblings work for the state television stationTVRI while his brother Imran is a district head in Rappocini, Makassar. According to Imran, as a child Abraham was hard-headed and forceful when he wanted something. Abraham, who enjoyed reading about Abraham Lincoln as a youth and considered the American president a hero, attended Kunjung Mae Elementary School in Makassar. He attended three different junior high schools, eventually graduating from Sulaiman Catholic Junior High School. He then finished his secondary education at Cenderawasih Catholic Senior High School. During this period he was known as a quarrelsome student.
Career
Abraham received a bachelor of law degree from Hasanuddin University; he later received his master's and doctoral degrees from the same institution, the latter in 2010. After receiving his bachelor's, Abraham began practising law two years later. He later founded the Anti-Corruption Committee of South Sulawesi, serving as its coordinator. The Jakarta Post describes Abraham as close to several conservative Islamic groups, including the Committee to Uphold Islamic Sharia, for which he acted as a lawyer. Though human rights activistBambang Widjojanto was considered the favourite for the KPK chair, the House of Representatives ultimately selected Abraham over both Bambang and the incumbent Muhammad Busyro Muqoddas; Abraham received a total of 43 votes, out of the 56 possible, while Busyro received five, Bambang received four, and Zulkairnain received three, and Adnan Pandu Praja received one. At the time of his election, Abraham was the youngest ever head of the KPK. Abraham said that he would work to improve the country's witness protection programme, improve cooperation between law enforcement agencies, and take steps to prevent – rather than merely react to – corruption. Some anti-corruption activists expressed disappointment in the decision, stating that Abraham had been selected to please political parties rather than to combat graft. Choky Ramadhan, a member of the Indonesian Judicial Watch Society, suggested that some candidates may not have been chosen as the political parties feared further attention would be paid to money laundering cases involving the parties. Tama Satrya Langkun, of the Indonesia Corruption Watch, noted that Abraham's career was sparse compared to that of the other candidates.
