What PT. Adiluhung Saranasegara Indonesia does

PT. Adiluhung Saranasegara Indonesia (ASSI) is a privately held Indonesian shipyard founded in 1992 and headquartered with principal manufacturing facilities in Bangkalan, Madura, East Java, supported by a sales and marketing office in Surabaya. The company provides integrated shipbuilding and ship repair services, operating physical infrastructure that includes a slipway with capacity up to 1,000 GT, a floating dock with heeling capabilities, a building berth, a metalworking workshop, and a concrete jetty capable of accommodating vessels up to 10,000 GT. To date, ASSI reports 66 new vessel constructions and 2,295 ship repair jobs completed, with a workforce of 176 engineers and workers (per company website).

ASSI is a vertically integrated subsidiary of PT. Dharma Lautan Utama, a major Indonesian shipping group, which acquired the shipyard in September 2007. The company's revenue model is project-based, with two primary streams: new vessel construction (Ro-Ro passenger ferries, container ships, hopper barges, and floating loading facilities) and ship repair and maintenance services (annual docking, floating repair, jetty/mooring services). All engagements are direct project contracts with no intermediaries. Customers are split between government transportation agencies (Ministry of Transportation, provincial and district Dinas Perhubungan) and private enterprise clients in shipping, energy, and mining (PT. Dharma Lautan Utama, PT. Hasnur Multi Sinergi, PT. Elnusa Trans Samudera, PT. Pelayaran Lestari Abadi Sakti). Marketing is relationship-driven through government tenders, IPERINDO industry networks, and trade events, with limited direct digital channels.

The company holds BKI classification certification, SMK3 Gold safety certification (95.78% external audit score, December 2023), and Zero Accident recognition (2015–2018). Its Direktur Utama, Anita Puji Utami, serves as Chairwoman of DPP IPERINDO (2022–2026), the national shipbuilding industry association, providing policy-level visibility. ASSI maintains vocational and university partnerships (SMKN 3 Bangkalan, SMKN 2 Sampang, Universitas Trunojoyo Madura, ITS, Politeknik Negeri Madura) for talent pipeline development, and has engaged with JICA and Austrade for modernization benchmarking.
