North Kalimantan Prosecutor's Office Probes Alleged Illegal Mining Case in Nunukan as Witnesses Questioned

The Special Criminal Investigation Team of the North Kalimantan Prosecutor’s Office (Kejati Kaltara) is continuing its probe into a mining case in Nunukan Regency, North Kalimantan. The prosecution is also investigating alleged involvement of several parties in the mining case. Andi Sugandi, Head of the Legal Public Relations Section at the North Kalimantan Prosecutor’s Office, stated that investigators have repeatedly summoned several witnesses strongly suspected to be involved in the case from Monday to Thursday (18-21 May 2026). Witnesses summoned include officials from the Ministry of Energy and Mineral Resources (ESDM), the Directorate General of the Ministry of Environment and Forestry (LHK), and KM, the President Director of PT Sebuku Inti Plantation (PT SIP). ‘Indeed, the investigation team has properly summoned witnesses from both government ministries and companies,’ Andi told reporters on Thursday (28 May 2026). However, he added that witness KM, who is President Director of PT Sebuku Inti Plantation and also Director of PT Central Cipta Murdaya (CMM), failed to appear without explanation or reason. ‘Several summoned witnesses from the Ministry of Environment and Forestry, as well as the President Director of PT SIP and Director of PT CCM, namely KM, failed to comply with the summons without providing any reason for their absence,’ he said. Andi noted that summonses had been issued to the witnesses, including KM, since Wednesday, 20 May 2026. The investigators will reschedule the questioning of those who did not attend. ‘This is the first summons for the individual concerned, so we will reschedule for further steps given the importance of the required testimony,’ he added. Separately, Boyamin Saiman, Coordinator of the Indonesian Anti-Corruption Society (MAKI), supported the Attorney General’s Office and its branches for their courage in investigating alleged illegal mining cases in Indonesia. ‘The minerals belong to the state. Illegal mining harms the nation and is subject to legal proceedings, with several cases already reaching court and resulting in guilty verdicts. We commend the prosecution for bravely investigating and pursuing illegal mining cases,’ he stated.
