The Back Door of Java


 

Every house has a front door and a back door. The front door is for guests, so you paint it, put a wreath on it at Christmas, and keep the walk shoveled. The back door is for garbage cans and muddy boots and things nobody wants to look at. Nobody goes out of their way to fix the back-door step. It rots a little every year, and you never quite notice until your foot goes through it.

Java had a front door and a back door too. The front door was the north.

Along that northern coast, the road we now call the Pantura grew into a highway corridor, then a string of busy ports, then the commercial artery that tied the island to the rest of the world. Down south the story ran the other way, in a long, quiet, sullen hush. Roads came slowly. Ports stayed small. The south waited, and nobody much noticed it waiting.

It would be easy to say that was nature’s doing. Easy, and wrong. Look closely at one small town called Cilacap and one narrow island called Nusakambangan and you find a different kind of story. Nature drew a rough sketch, but men with maps and muskets and ledgers did the inking. Someone decided which stretch of coast would become a road, which a market, and which a fortress. It wasn’t the sea that decided.

The historian Susanto Zuhdi put it plainly in his 2014 study of the southern coast (page 175, for those who like to check). The isolation was not purely a gift of geography. Yes, the roads were bad and the terrain was worse. But in Javanese history, Zuhdi says, the rulers kept their eyes fixed northward, and the south came to be thought of as the backyard.

You know what lives in backyards. Things you’d rather not think about.

And the sea did its part. The Indian Ocean doesn’t lap at the southern shore of Java. It hits it, with long, heavy, patient swells that have come thousands of miles across open water with nothing to slow them. Try to anchor a ship in that and you will learn, quickly and expensively, what the word no means. So the little ports along that coast, Prigi and Pacitan and Pelabuhan Ratu, made do with what they could. Salted fish. Salt. Shrimp paste, which is the kind of thing you smell before you see. Honest trade, but small. Big ships didn’t stop there if they could help it.

Up north, it was another world entirely. Cirebon, Pekalongan, Tegal, Batavia, Semarang, Surabaya: the gateways of the Javanese kingdoms, the places where the island opened its mouth to the world and the world put things in it. Iwan Hermawan, writing in 2014 about the railway that would one day link Batavia to Cilacap, points out something worth sitting with. The great postal road, the one that ran from Anyer all the way to Panarukan, was not built to carry letters. Or not only to carry letters. It was built to move soldiers. Fast. Between Batavia, Semarang, and Surabaya, because in wartime, speed is the difference between a bad day and a lost colony.

The road did climb through the highlands near Bandung, yes. But look at where it was going. It was stitching the port cities together, and the inland axis was just a seam in the cloth.

That was the north. A map of the south looked very different.

And yet, in the middle of all that quiet, one place stood up and waved its hand.

Cilacap.

Why there? Because of an island, and the island was Nusakambangan. Put your finger on the map and you’ll see it lying along the coast like a long dark animal asleep in the water, forty kilometers nose to tail and about six kilometers across. It stands between the bay and the ocean, and when the great swells come rolling in from the south, Nusakambangan takes the blow so the water behind it can stay calm. A natural breakwater. A gift.

Ships could dock there without being smashed to kindling. As Astrid Teresa Viliana and Zulkarnain conclude in their 2018 study of the port, that safe harbor shaped everything that followed.

The Dutch were not fools, and they didn’t leave a gift lying on the table. Zuhdi notes that they actually preferred developing the south over the north for one practical reason: time. Plenty of inland produce could reach the sea faster by the southern route. But notice the shape of that choice. Of the whole long string of southern coastline, only Cilacap got the attention. The rest stayed in the dark.

And the attention wasn’t only about money.

An island like that, one that guards a harbor, is a thing you fortify. Devy Dhian Cahyati’s research (2017, page 6) says the Dutch started reinforcing troops on Nusakambangan in 1819, to keep the place safe from enemy attack. Then the Diponegoro War came along and swallowed their attention whole, the way wars do.

The popular sources, Tirto.id and Kompas.com among them, tell it a little differently. They say work on the watch forts didn’t begin until 1836, and that the immediate worry was pirates. Pirates who prowled around the island, took cargo and food, and sometimes took people. (You can imagine how that went down in the little villages along the shore. A fishing boat doesn’t come home, and nobody ever says the word kidnapped out loud, but everybody thinks it.)

Then, in 1850, malaria arrived and stopped the work. Sickness has never read a Dutch construction schedule. But the forts needed building, so the Dutch found another source of labor, men who couldn’t say no: convicts.

That’s how it began. Men in chains hauled stone onto an island, and the island learned what it was for.

By 1905, though some sources say 1908, Nusakambangan was declared a restricted zone, and the first prison went up. Think about that for a moment. The same island that sheltered ships from the sea was now sheltering the colony from its own prisoners. The same walls kept some things out and other things in.

The defense plan ran in layers, like the skin of an onion. Forts Karangbolong and Cimiring stood on Nusakambangan as the first line against anyone coming from the east. Fort Pendem, over in Cilacap itself, was the last layer, the one you’d fall back to when everything else had gone wrong (Zuhdi, 2014: 180).

Lay that beside the northern postal road and the pattern jumps out at you. In the north, the army’s needs made roads, long bright ribbons connecting one port to the next. In the south, those same needs made forts and a guarded island, all of it crowded into a single point on the map.

But a sheltered bay is only a bay. It doesn’t turn into a port until something arrives to be shipped.

For Cilacap, that something arrived after 1830, when Banyumas was drawn into the Cultivation System. Coffee. Indigo. Sugar. All the green and growing wealth of the interior, and every ounce of it had to be dragged to the sea.

The roads were chaos, so the rivers did the work. Trade between 1830 and 1856 moved at a crawl. In 1836, the value of trade actually dropped, because produce got stuck somewhere between the mouth of the Serayu River and the harbor (Viliana & Zulkarnain, 2018: 633–640). Picture it: barges full of coffee sitting in the heat while the days leak away.

The colonial government wasn’t short on ideas. They dug a canal, the artificial Kali Yasa, finished in 1837 to connect the interior to the port. Exports picked up. But it wasn’t an easy birth. The technology was crude, and the water would not always flow the way the engineers insisted it should. Canals have a way of going still. A stagnant canal is a bad thing to depend on.

So the Dutch reached for iron.

The Staatsspoorwegen, the colonial government’s railway company, built the Yogyakarta–Cilacap line, beginning in 1879 and opening it in 1887. A year later the track ran on from the station to the harbor itself. Now the goods could travel quickly from the interior to the waiting ships. Tamimi and Antariksa (2018: 4) note that one of the important cargoes was sugar from Yogyakarta.

Hauling produce was the reason they gave. It wasn’t the only one. Hermawan (2014: 129–139) notes that the railway network was meant for the army, too. On 1 November 1894, the Cilacap line was joined to Bandung and Batavia, and the connection had very little to do with sugar. The rails could carry troops and supplies to Bandung and Cimahi. And they could carry something else: the possibility of getting civilians and government leaders out, quickly, if things went bad.

If things went bad. The Dutch, you’ll notice, were always planning for that.

In 1942, things went bad.

In the last days of February, with the Japanese closing in, the civilian government packed up and moved from Batavia to Bandung. Cilacap became a door in the wall. The emergency exit. People were put aboard ships bound for Australia and Sri Lanka, and some of those ships never got there. The Japanese sank several of them (Cahyati, 2017: 6). The exit led out into dark water, and some of the people who went through it didn’t come out the other side.

But the rails had been doing something else for a long time, something the Resident of Banyumas must have watched with a growing cold feeling in his stomach.

In 1917 the Cirebon–Kroya line was completed. Now the produce of Banyumas could go to Cirebon. The Batavia line opened another possibility: export through Tanjung Priok. Every one of those options was a new road out of Cilacap, and the Resident worried about what that meant for the future of his region. Zuhdi (2014: 175–179) describes the pattern exactly. The wider the web of road and rail spread, the easier it became for the inland goods to simply walk past Cilacap on the way to Semarang, or Cirebon, or Jakarta.

By 1924 you could see it in the newspapers. De Locomotief reported that Semarang and Cilacap were competing for the sugar from the Yogyakarta factories. Cilacap still had one card left: exporting from western Central Java by that route was said to be ten percent cheaper than going through Semarang. But you don’t have to be a gambler to know what a declining edge looks like.

Cilacap’s pull as a commercial route began to fade. What did not fade was its other job.

The war of 1942 ended Dutch supremacy. The Japanese attack left the port largely out of action. But the shape of the place, all the forts and the guarded island and the defensive order stamped into the land, did not die with the empire that made it. Things like that rarely do.

After independence, parts of the old colonial defense zones passed into the hands of the Indonesian military. Cahyati (2017: 5–7) records that the KNIL was disbanded in 1950 and that a number of its facilities were handed to the TNI. That history of control later became one of the grounds on which the military held on to certain stretches of land along the Kebumen and Cilacap coasts.

Think about what that means. Power changed hands. Flags came down and other flags went up. And the ground itself stayed claimed, as if the land remembered who had owned it and obeyed the old rules anyway.

That is the legacy. The colonial infrastructure left behind patterns of control that outlived the colonizers, and in the end those patterns locked up wide stretches of the southern coast. They couldn’t grow into commercial zones on the scale of the north. The door had been bolted from the inside, and the people who’d bolted it were long gone.

So here is what the history of Cilacap really tells you.

The south was never built to stand on its own two feet. From the start, it was built to serve: to defend the colony and to drain it. The forts on Nusakambangan, the railway, the canal, every piece of it was laid out as a security belt, an evacuation gate, a drain for the produce of the interior. Nobody asked what the south might have wanted to become. Nobody asked what it might have been, left alone.

And so, while the Pantura cities were whipped along as commercial arteries, the southern coast fell behind. It wasn’t just the surf, and it wasn’t just the bad roads. It was boxed in by military control whose shadow reached all the way into the Republic.

Zuhdi (2014: 178) calls it a historical irony, and that irony has not gone away. The development of the southern coast has never quite managed to slip free of what the north wants.

The back door, in other words, is still the back door.

And if you go down there and stand on that old step, with the Indian Ocean throwing itself at the island, you might hear it: the sound of a very long wait, still going on.
