The Director General of Oil and Gas at the Ministry of Energy and Mineral Resources, Laode Sulaeman, stated that the commissioning of Cisem II is a significant achievement in national energy infrastructure development. ‘Following the success of Cisem I, today we witness the commissioning of Cisem II, which completes the connectivity of the natural gas pipeline network on Java Island. This infrastructure strengthens national energy security and improves the system’s capability to distribute gas to various regions and user sectors. We appreciate all parties who have collaborated so that this strategic project can be completed and operated properly,’ said Laode. PGN Commercial Director Aldiansyah Idham stated that the success of the Cisem II commissioning demonstrates the PGN Group’s commitment to maintaining the sustainability of the national natural gas business through infrastructure strengthening and optimisation of domestic energy utilisation. ‘The Metering System commissioning at Kandang Haur Timur is an important part of moving towards full optimisation of the CISEM II infrastructure, thereby providing better flexibility and reliability for the national gas transmission system,’ said Aldiansyah. President Director of Pertamina Gas, Indra P. Sembiring, confirmed the full operational readiness of the Cisem II system. ‘With the completion of commissioning at Kandang Haur Timur, the Cisem II system is ready to be operated and becomes a vital part of the national gas transmission network, which is now connected from East Java to West Java. Pertagas has prepared facilities, infrastructure, and personnel spread from East Java to West Java to ensure this infrastructure operates safely, reliably, and optimally,’ said Indra.
