Sardjito Hospital Switches to Natural Gas, Achieving 75 Per Cent Efficiency
SLEMAN – The switch of fuel from biosolar to natural gas has made operations at Dr. Sardjito General Hospital (RSUP) in Yogyakarta more efficient. Natural gas from PT Perusahaan Gas Negara (PGN) is used for the hospital’s steam boiler as well as for cooking in the hospital kitchen.
Arismantoro, a maintenance technician with the hospital’s Facility Maintenance Installation (IPSRS), said the natural gas is used to produce steam from the boiler, which is then used for a number of the hospital’s needs.
“So the use of gas at RSUP Dr Sardjito serves two purposes: for the operation of the steam boiler, where the output taken is its steam,” Arismantoro said at RSUP Dr. Sardjito in Sleman, Yogyakarta, on Tuesday (15/9/2026).
Arismantoro explained that steam from the boiler is used for the Central Sterile Supply Department (CSSD), the central sterilisation installation that manages, sterilises and distributes medical instruments. The steam is also used to support the hospital’s laundry operations.
In addition to the boiler, natural gas is also used for cooking in the hospital kitchen. This gas usage replaces the biosolar previously used for certain operations.
According to Arismantoro, the transition from biosolar to gas has yielded significant efficiency gains. Previously, RSUP Dr. Sardjito used around 1,000 litres of biosolar per day, while the efficiency from using gas averages around 75 per cent, although the exact figure still depends on the hospital’s operational patterns and intensity.
“So far, with gas, our average efficiency has been around 75 per cent,” he continued.
Beyond efficiency, the use of gas is also considered beneficial in terms of emissions. Arismantoro said that using gas results in lower carbon monoxide (CO) emissions compared to when the hospital still used biosolar.
“What is clear is that in its use, we benefit from the efficiency. Then, regarding exhaust gas, our exhaust is automatically safe from CO. So in terms of emissions, we are safe from CO,” he said.
When it was still using biosolar, the hospital had to carry out further treatment and maintenance, particularly relating to the emissions produced. With gas, these requirements are considered simpler.
On the supply side, Arismantoro said RSUP Dr. Sardjito has so far encountered no problems. The gas supply comes from a central source and is adjusted to the hospital’s operational needs.
“Its reliability depends on availability. Since the supply comes from a central source, we have had no problems so far. Our needs are met accordingly,” Arismantoro added.
Arismantoro said the decision to use gas was made primarily with operational efficiency in mind. The use of gas is also seen as being in line with efforts to support the government’s programme on natural gas utilisation.
“This is also part of supporting the government’s programme,” Arismantoro said.
