What Triasmitra Group does

PT Ketrosden Triasmitra Tbk (Triasmitra Group) is an integrated Indonesian telecommunications infrastructure company founded in 1994 and listed on the Indonesia Stock Exchange (KETR) since November 10, 2022. It builds, owns, and operates submarine and inland fiber optic cable systems across Indonesia, deploying more than 10,000 km of cable across named systems including B2JS (1,070 km), SDCS (520 km), UJB (2,661 km), Jayabaya (875 km), DAMAI (572 km), and the newly launched Rising 8 (1,128.5 km, 25 Tbps per fiber pair, up to 400 Tbps total capacity).

The company operates through three business lines: a Developer business that builds cable systems and sells fiber cores to telecom operators (historically ~70% of revenue), a Managed Service business that operates and maintains Triasmitra-owned and customer cable systems via a proprietary 24/7 Network Operation Center (NOC) with filed patents and Bakamla RI integration (~25% of revenue, recurring), and a Contractor business that builds third-party cable systems (~5% of revenue). Strategic physical assets include CLV Bentang Bahari — Indonesia's first domestically-flagged Cable Laying Vessel (94.65m, 2,400-ton cable capacity, DP-2 and DNV certified) — and a Tier-3 Cable Landing Station/Data Center at Tanjung Pakis.

Triasmitra serves 30+ telecom and technology customers including Telkom, Indosat, XL Axiata, Biznet, Singtel, Telstra, Google, and Linknet, monetizing infrastructure via one-time core sales, multi-year IRU agreements (e.g., the September 2025 IRU with PT Remala Abadi covering five backbone systems), recurring managed service subscriptions, and outcome-based cable repair. The company employs direct enterprise sales targeting telecom operators and Network Access Providers, with strategic positioning on the Indonesia-Singapore corridor. FY2025 revenue was Rp750 billion (up 35% YoY) with net profit of Rp138 billion (up 63%), and management targets Rp1.01 trillion for FY2026, supported by the SKKL Merindo project (8,732 km, RFS targeted 2027) and rising third-party vessel charter demand.

Direct peers

• Fiberstar: Indonesian fiber optic infrastructure provider offering wholesale and enterprise fiber services. Listed as a Triasmitra customer but also operates competing fiber networks in Indonesia, making it a peer in both directions of the value chain.
• Moratelindo: Direct peer operating submarine cable systems in Indonesia including Palapa Ring Barat (where Triasmitra held 10% consortium stake). Moratelindo is one of the ASKALSI member companies and a competitor in the same submarine cable infrastructure market, with overlapping customers in Indonesian telecom operators.
• iForte Solusi Infotek: Indonesian fiber network operator serving enterprise customers with metropolitan and long-haul fiber infrastructure. Listed as a Triasmitra customer but also a competitor in the Indonesian fiber infrastructure market, particularly for enterprise customers.
• Biznet: Indonesian fixed-line telecom operator and fiber network owner with significant inland fiber infrastructure. Biznet is both a customer and a competitor to Triasmitra, building its own fiber backbone across Java, Bali, Sumatra, and other islands — overlapping with Triasmitra's UJB and inland cable business.
• PT Mora Telematika Indonesia (MORA): Direct peer and joint venture partner on Rising 8 submarine cable system. Mora Telematika is a major Indonesian submarine cable and fiber network operator, co-developing the SKKL Rising 8 segment with Triasmitra. Highly comparable in business model (submarine cable developer/operator) and target market (Indonesia).
• PT Infrastruktur Telekomunikasi Indonesia (Telkominfra): Direct peer and joint venture partner on the DAMAI (Medan-Dumai) cable project. Telkominfra is a Telkom subsidiary providing telecom infrastructure including fiber optic cable maintenance and construction services across Indonesia, with overlapping submarine and inland cable capabilities.

Broad incumbents

• Indosat Ooredoo Hutchison: Major Indonesian mobile operator and Triasmitra customer. Indosat invests in submarine cable consortiums (SEA-ME-WE, Indigo) and procures fiber infrastructure, making it both a customer and an indirect competitor with vertically-integrated telecom infrastructure capabilities.
• Alcatel Submarine Networks (ASN): Global submarine cable systems supplier and Triasmitra's partner for repeater technology on Rising 8. ASN designs, manufactures, and installs submarine cable systems globally and could be viewed as a broader incumbent with potential to vertically integrate into ownership/operation of cable systems, threatening traditional developers.
• PT Telkom Indonesia (Telkom): Indonesia's largest telecom operator and a major Triasmitra customer through Telin. Telkom has its own submarine cable subsidiary (Telkominfra), operates international cables via consortiums, and competes with Triasmitra on large-scale infrastructure projects. A broad incumbent that overlaps with Triasmitra's developer business.

Regional players

• Singtel: Singapore-based tier-1 international telecom operator and Triasmitra customer. Singtel owns and invests in numerous submarine cable systems in Southeast Asia (ASEAN Cable, SEA-ME-WE, APCN) and serves as the primary landing partner for Indonesian cables at Singapore — comparable in operating cable infrastructure but primarily Singapore/regional focus rather than Indonesian.
