What fuels Cilacap’s economy?
Cilacap is a town in the southwestern part of Central Java, Indonesia. It sits on the southern coast of Java at latitude ‑7.72639 and longitude 109.00944.
The town’s harbour, one of the few on Java’s southern seaboard, serves national and international shipping, linking the region’s agricultural hinterland to global markets.

A geothermal power plant supplies electricity to the surrounding area, while a cement plant operated by Holcim Indonesia and a major Pertamina petroleum‑processing unit contribute significant output. The Pertamina facility is noted for its large production capacity and product diversity compared with other national sites.
These industries are supported by transport infrastructure, including Tunggul Wulung Airport and road connections to Jakarta and Semarang, facilitating the movement of goods and labor. The combination of a strategic coastal position, protected harbour, and diversified industrial base makes Cilacap a key economic hub in the region Cilacap Regency.

03 · OverviewCilacap, in brief
Cilacap is a city in the southwestern part of Central Java, Indonesia.
It sits on the southern coast of Java at latitude ‑7.72639 and longitude 109.00944.
Where is Cilacap situated within the province?
Cilacap lies within Central Java province, forming the administrative centre of the town that is part of Cilacap Regency. The regency covers a land area of 2,323.93 km², which includes the 115‑km² offshore island of Nusakambangan. While the regency’s mid‑2025 population estimate is 2,046,392, the city itself records a population of 256,996 according to official statistics.
How does the southern coastline shape the city’s economy?
The city’s harbour is one of the few ports on Java’s southern shoreline capable of handling vessels of reasonable tonnage, with the nearest safe anchorage to the east located at Pacitan. This strategic position supports national and international trade, linking the port to industrial facilities such as a geothermal power plant, a Holcim cement plant, and a Pertamina petroleum‑processing unit that boasts the largest production capacity among the company’s sites.

What natural features protect Cilacap from ocean hazards?
The harbour is shielded by Nusakambangan Island, an area better known for high‑security correctional facilities but also eyed for future tourism development. During the 2004 Indian Ocean tsunami, the island’s barrier helped spare Cilacap from the worst effects, though the disaster still claimed 147 lives, damaged 435 fishing boats, and caused material losses estimated at Rp 86 billion (about $9 million).
