PT Pupuk Kalimantan Timur, through Document K-SML-07 dated 15 September 2023, has established the PT Pupuk Kalimantan Timur Biodiversity Protection Policy, which emphasizes the designation of conservation areas and support for the Sustainable Development Goals (SDGs).




Implementation of this policy is carried out in collaboration with stakeholders including the Kutai National Park Authority (TNK), the Reef Check Indonesia Foundation, the East Kalimantan Provincial Marine and Fisheries Office, the Bontang City Environmental Agency, PKSPL IPB University, and community leaders.








Since 2023, Pupuk Kaltim has obtained the Sea Space Utilization Suitability Approval (PKKPRL) No. B472/MEN-KP/IV/2023 from the Ministry of Marine Affairs and Fisheries for an area of 10 hectares in the waters of Tebok Batang and Pasilan, Bontang City. The designation of this area as a conservation zone underscores the Company’s commitment to rehabilitating coral-reef ecosystems, a program that has been carried out consistently every year since 2009.



In partnership with fisher groups under the Company’s Corporate Social and Environmental Responsibility (TJSL) program—specifically the Kilau Samudera group—Pupuk Kaltim routinely produces and deploys artificial reef units in the waters of Bontang City. Notably, in 2025, Mr. Jusman, an activist from the Kilau Samudera group, received the East Kalimantan Kalpataru Award in the Environmental Savior category for his contributions to the restoration of Bontang’s coral-reef ecosystem. 




To date, the Company has carried out biodiversity conservation efforts, including the cultivation of rare plant species, conservation of the endemic black orchid, preservation of the sambar deer, mangrove planting in Kedindingan and HGB-65 areas, as well as coral reef conservation in Tobok Batang.
