One Year After Killing Gamma, Robig Zaenudin Finally Dismissed as Police Officer
Convicted in the shooting of SMKN 4 Semarang student Gamma Rizkynata Oktafandy, Aipda Robig Zaenudin has been officially dismissed as a member of the Indonesian National Police (Polri). The dismissal occurred shortly after his transfer from Class I Semarang Penitentiary to Nusakambangan Penitentiary due to suspicions of controlling drug distribution from within the prison.
“Robig is no longer a Polri member. As of 18 February 2026, he has been officially dismissed,” stated the Head of Public Relations of Central Java Police (Polda Jateng), Kombes Pol Artanto, during an interview at Polda Jateng headquarters in Semarang on Friday (24/4/2026).
Artanto explained that the decree from the Central Java Police Chief regarding Robig’s dismissal or dishonourable discharge (PTDH) was directly handed to his family. “On 18 February, the PTDH decree was received by the family. Without a ceremony, it was officially delivered. Personnel from Semarang Police Headquarters HR visited the family and handed over the decree,” he said.
Robig was decided for PTDH by the Polri Ethics Code Commission (KKEP) on 9 December 2024. He appealed the decision, but it was rejected. Thus, Robig was officially dismissed one year and two months after the PTDH decision.
Robig has now been transferred to Nusakambangan Penitentiary. The transfer was due to suspicions that he was controlling drug distribution from inside the prison.
Artanto revealed that on 19 January 2026, the Central Java Police Narcotics Directorate (Ditresnarkoba Polda Jateng) along with the Central Java Regional Office of the Directorate General of Corrections conducted an inspection at Class I Semarang Penitentiary. “During the examination, Robig was found to be in an unstable condition or the individual was in a precarious state,” Artanto said.
Noticing the irregularity in Robig’s condition, officers searched his detention room and conducted a urine test on him. “It was found that Robig tested positive for drugs,” Artanto stated.
Nevertheless, Artanto added, the search did not uncover drugs or other prohibited items such as mobile phones or gadgets in Robig’s cell. “However, his unstable physical symptoms raised suspicions from both the police and prison authorities regarding the individual. Therefore, a urine test was immediately conducted,” he explained.
Artanto said the case is still under investigation by Ditresnarkoba Polda Jateng. “Whether the individual is acting as a distributor or merely a user is being thoroughly examined by the Central Java Police Narcotics Directorate, and we await the investigation results,” he said.
When asked about the type of drug Robig consumed, Artanto could not yet answer. He stated that it is still being investigated by Ditresnarkoba Polda Jateng. “But the urine test was positive for drugs. Whether it’s methamphetamine or another drug, we are still inquiring,” he said.
Artanto disclosed that Robig was transferred from Class I Semarang Penitentiary to Nusakambangan on 4 February 2026. Artanto assured that Polda Jateng will process Robig legally, including if he is proven to have controlled drug distribution from the prison.
“Of course, anyone who commits a drug-related criminal offence will be processed legally. We will see the developments of the investigation by the Narcotics Directorate regarding Robig,” he said.
Head of Class I Semarang Penitentiary Ahmad Tohari confirmed that Robig’s transfer to Nusakambangan was prompted by the drug control case. “Class I Semarang Penitentiary received several complaints from the public regarding allegations of drug control outside the prison by one of the inmates named Robig Zaenudin,” Tohari stated in his comments obtained by Republika on Thursday (23/4/2026).
He added that a few days later, Ditresnarkoba Polda Jateng examined Robig. “Therefore, as a precautionary measure against this issue, Class I Semarang Penitentiary took swift action to transfer the inmate to Class IIa Gladakan Nusakambangan Penitentiary to prevent potential disruptions to security and order,” Tohari said.
Tohari revealed that 40 inmates, including Robig, were transferred from Class I Semarang Penitentiary to Nusakambangan Penitentiary. The transfer took place on 4 February 2026.
Twenty inmates were sent to Class IIa Gladakan Nusakambangan Penitentiary. The remainder went to Class IIb Nirbaya Nusakambangan Penitentiary. The transfer of the prisoners was carried out based on the Decree of the Head of the Central Java Directorate General of Corrections Regional Office Number: WP.13-PK.03.02-29 dated 30 January 2026.
Aipda Robig Zaenudin was a member of the Narcotics Sub-Directorate of Semarang Police Headquarters. On 24 November 2024, he shot three SMKN 4 Semarang students. One of the victims, Gamma Rizkynata Oktafandy (17 years old), died in the incident.
On 8 August 2025, the panel of judges at the Semarang District Court (PN) sentenced Aipda Robig to 15 years in prison. He was declared legally and convincingly guilty in the shooting of three SMKN 4 Semarang students, which resulted in the death of one victim, Gamma Rizkynata Oktafandy.
The panel of judges stated that Aipda Robig was proven to have violated Article 80 paragraph (3) and Article 80 paragraph (1) of Law No. 35 of 2014 on Child Protection. “Imposing a prison sentence on the defendant for 15 years and a fine of Rp 200 million, with the provision that if the fine is not paid, it shall be replaced with imprisonment for 1 month,” said Chief Judge Mira Sendangsari when reading the verdict against Aipda Robig.
The prison sentence against Aipda Robig matched the prosecutor’s demand. According to the public prosecutor (JPU), Aipda Robig had legally and convincingly committed violence against a child resulting in death and injury.
“That during the trial, no reasons were uncovered that could eliminate the defendant’s actions, whether justifying or excusing reasons,” the JPU stated during the prosecution hearing at PN Semarang on 8 July 2025.
Robig appealed the verdict, but his appeal was rejected by the Central Java High Court.
