These old mills are really quite WYSIWYG, for the most part you can follow the process with your eyes. However, what may not be apparent is the degree to which little is wasted and how marginal juices and syrups are recycled. The same is true for energy, the factory boilers burn bagasse and even the waste steam from the milling engines is used in the juice heaters. The flow diagrams for the process are like spaghetti.

Nice to see the interesting process of sugar making. First time I am seeing the sugar factory and without fast forwarding.Thank you and thanks to the factory’s management for filming such a fantastic experience.

Most people don't know what it takes to get simple luxuries from the grocery store. Thanks for sharing.

how pure amazing this video was, wonderful shoot to this video Mr. Rob, thankyou so much. after the steams locomotives, i think this was the most another impressive antique stuffs i have ever seen. Cheers Rob, great works!

My father worked in this factory in 1953 - 1958 as a bookkeeper. We lived inside the factory compound. In 1957 it was nationalized and changed the name to PG Gondang Baru (previously it was Suiker Fabrieke Gondang Winangun). Great Job Rob! Bring back my beautiful memories as a 10 years old boy living there.

I'm glad you found the video. This mil was made to last, when the earthquake struck the Yogya area in 2006, the mill was closed for a couple of days but only so the staff could effect essential repairs to their homes outside. The Administrator said that he wasn't at all worried as it had been built properly by the Dutch many years before. It will have hardly changed since you knew it save that the Fulton Corliss engine used as the crusher had been replaced by a Stork drop valve engine.

Thanks for filming and sharing this piece of working history. We have very few working steam engines let alone a whole factory. I hope it's never replaced with a modern update.

Omg, it's a very complex process to get one spoon of sugars for our coffee. Salute to the technology and those people.

Thanks, as amateur industrial archaeologists, it was a privilege to be able to capture this while it was still working. Of course, it was just the #1 of many similar mills in Java at the time. Sadly, most of the 'best' have also closed down too.

To watch the speed of the piston is truly astounding. The power this machine has is incredible. I could stand there all day or even a week being amazing how this thing works and operates.

Wow, I enjoyed every second of this very well made documentary. It was like someone took a video camera back in time to see how this factory ran a century ago. I know it's old technology but what's wrong with that. A modern operation would put three quarters of these people out of work. I'm guessing you work your way up at this factory from shoveling limestone all the way up to relaxing in a chair turning a steam valve. I would have liked to see the molasses and brown sugar operation.

I am surprised to see the mind blowing old machinery in mills house, boiler, power house and process house. The oldest types of locomotive engines working as today,s steam turbines. Different types of pumps & manual centrifugals are amazing , excellent informative video 👍👏

Very impressive presentation and the industrial history so evident - the early machinery was certainly made to last. Would never have thought such Ind Rev still operates economically not just museum. Many thanks.

The factory started in 1860 but was then driven by water power. In the late 1800s it was converted to steam and also expanded greatly. Unfortunatley it was closed in 2017 and is today a museum.

Fantastic production, well done chaps. Saw a steam powered rum factory on the island of Grenada, Caribbean a few years ago, that too was running 1880's machinery, mostly built in Colchester, UK. Well Done.

Amazing to see these machines still running like they have been since colonial times at least since over 100 years even more, not polished and shiny and only running on special shows but still doing their business since the day they were installed. Manufacturers like Stork Hengelo and Werkspoor in Holland for sure are long out of business but their products were built for eternity. Lentz valve mechanism on the crusher engine if I'm not mistaken.

Indeed. The development of mills like this followed immediately after the first railways in Java and most, like this one, had a short branch to the nearest station. As such, all components would have been of a size to fit within the railway's loading gauge and weight limits. Some of these branches survived quite late on into the 1970s and 1980s by which time they were used to bring in fertiliser etc and used for shipping out molasses. Here, they used a lovely old tram locomotive which is now preserved in the mill's grounds.

It's cool that they have a mill shop which presumably maintains and re-builds tools/machinery. I was thinking about the insane number of people it probably took to build all of that machinery, and the number of people required to run that factory today. Wikipedia says they burn the stalks and other parts of the plant used in the process as well as the molasses (which you see them pouring into the coal powder bricks in this video, which could be the reason they're still using steam. If they had to "upgrade" to all electric, they'd need to buy an insane amount of electric motors & maybe import more fuel which I assume isn't worth the cost given the old stuff works. There were several electric motors powering various machines shown in the video so maybe if something breaks they'll go with electric. It's crazy that they basically produce everything including electricity on-site, except for sugar cane, coal, and water. Would like to see all the smoke stacks & the area surrounding this place. 😅

The video was shot about 10 years ago. The last time I visited the mill in 2010 it was exactly the same - after which my personal circumstances changed. I have no reason to believe it has greatly changed since then although it is possible some of the smaller pumps have been replaced. The most likely development will be that the mill will cease production and be declared a museum. There is a continuing debate as there has been for as long as I can remember about the sugar industry in Java as to whether it is worth spending a lot of money to modernise it which will necessarily result in the loss of many jobs in mainly rural areas. Efficiency would come at very high price. What this film doesn't show is that sugar cultivation is largely unmechanised and also labour intensive.

Of all the 'unskilled' labor i have ever done: *bailing hay* *Cutting and picking tobacco* *grinding fiberglass boats, fully suited in a tyvek in the summer in south Florida* *digging trench ditches for piping, and French drains* Easily the most hard: *cutting sugarcane in the Everglades in Florida*

Furthermore it is amazing how do they work , and how integral the process is.

Indeed, safety was your personal responsibility. The Chief Engineer of such a mill would have had to be a 'jack of all trades' and need skills in all the facets of 'engineering' and even more so once the equipment reached this age. Fortunately, everything was built to last and maximising profits came second.

Kudos to them for going through all that process to make sugar, we in America just have to push buttons, and some looking into, and the computers take over the work. But for them, it's make the steam for the steam engines, find the right amount of steam for the amount coming in, and just way to many other things for me to say!

No incentive to make the jobs less stressful as labor was undoubtable plentiful with labor costs being the lest of the owners concerns. How did they ever keep all those contraptions running.
