At about 4 a.m. on Friday, 28 August 2026, a house in Kampung Pulo Kapuk, Mekarmukti village, North Cikarang, exploded while the mother was warming rice in the kitchen. Six members of one family were burned. A 36-year-old father and his 7-year-old son died at the Bekasi Regency hospital; four others were treated at two hospitals.
Suta, 41, a member of the village health task force, told CNN Indonesia: "The gas leaked, then he tried to change it, and there was already fire." Bekasi Metro Police's head of criminal investigation, AKBP Jerico Chandra, said witness accounts pointed to the gas cylinder. The exact cause is still under investigation.
This happened in Bekasi Regency, not Kota Bekasi. But the kitchen looks like anyone's: one stove, one cylinder, one hose, and one regulator that gets clipped on and off every time a cylinder runs out. That connection is the weak point.
Why a leak can explode
LPG is heavier than air. The Ministry of Energy (ESDM) says so in its safe-use guidance: gas escaping from a joint doesn't rise to the ceiling. It sinks and pools near the floor, under cabinets, in corners where the air doesn't move. Until it meets a flame or a spark, that pool just sits there.
The spark doesn't have to be a lighter. A light switch, a plug being pulled, a fridge compressor kicking in, the stove's own igniter. That's why the ESDM guidance asks for something that feels backwards: if you smell LPG, don't switch any electricity on or off.
The "gas smell" you know is an odorant added on purpose, because LPG itself has almost no smell. So your nose is the first detector in the house. A faint smell that keeps coming back every morning is a small leak you haven't found yet.
Where leaks usually are
Rarely in the cylinder body. The weak points are the joints, and there are several:
| Point | What usually goes wrong | How to check |
|---|---|---|
| Rubber seal in the cylinder valve | Missing, torn, or flattened at the filling plant | Look into the valve opening before fitting the regulator |
| Regulator on the valve | Not fully locked, lever not down | Soapy water around the joint |
| Hose | Brittle, hairline cracks at bends, chewed by rats | Bend it gently along its length, brush with soapy water |
| Clamps at both hose ends | Loosened after the stove was moved | Make sure both clamps are on and tight |
| Stove inlet | Hose pushed on with no clamp | Soapy water at the stove end |
ESDM says the hose must be clamped firmly at both the regulator and the stove, and the regulator must sit tight on the valve. It sounds trivial, so it rarely gets checked.
A five-minute soap test every cylinder change
This is the method the ESDM guidance recommends. All you need is dish soap and a little water.
- Before fitting the regulator, look at the rubber seal inside the new cylinder's valve. If it's missing or damaged, don't use that cylinder. Return it to the agent.
- Lock the regulator on and open the gas. Keep the stove off.
- Brush soap foam on the valve joint, along the hose, on both clamps, and at the stove end.
- Wait a moment. A bubble that keeps growing means gas is escaping there.
- If you see one, close the gas, remove the regulator, and fix or replace that part before cooking.
Never test with a flame. It sounds obvious, yet "just hold a lighter near it" is still a habit in plenty of homes.
The lesson from Cikarang is about order. Changing a cylinder while there's still a flame in the kitchen, or after you've already smelled gas, are two things that must never meet. Turn the stove off, make sure there's no other flame in the room, open the doors and windows, then change the cylinder.
How long hoses and regulators last
Buy a regulator and hose with the SNI mark, as ESDM recommends. As for replacement, the common manufacturer advice is roughly every two years for a hose and five years for a regulator, or whatever the packaging says. A hose that feels stiff when bent, has changed colour, or is cracking near the clamp should go now, whatever the date.
Write the fitting date on the regulator with a marker. In two years you won't remember.
Three more kitchen things people miss
Fully closed kitchen cabinets
A cylinder tucked into the base cabinet looks tidy. The trouble is that a closed cabinet is the perfect place for a heavier-than-air gas to collect. If the cylinder has to live there, cut vents near the bottom of the cabinet door and keep things off the hose. ESDM also notes that kitchen ventilation works best low on the wall.
The spare cylinder
Keep it upright, in shade, somewhere ventilated, away from the stove and any heat source. The carport or a service area at the back of the house beats a cramped corner of the kitchen.
Mount the gas detector low
Smoke detectors go on the ceiling because smoke rises. An LPG detector is the opposite: it goes near the floor because the gas sinks. If the house ever switches to piped natural gas, the placement flips again. Natural gas is lighter than air, so that detector goes high.
In a cluster where houses sit close together, a leak in one kitchen isn't only one family's problem. A 4.5-metre-wide house like the Emerald 70 on Jl. Raya Perjuangan, North Bekasi, usually has a compact kitchen, and the smaller the room, the faster leaking gas fills it. That's reason enough never to skip the soap test at a cylinder change.
If you smell gas
- Don't touch light switches, don't pull plugs, don't light anything.
- Close the stove knobs, then take the regulator off the cylinder.
- Open doors and windows as wide as they go so the gas near the floor can clear.
- If it's safe, carry the cylinder outside.
- Call from outside the house: Pertamina's call centre on 135 for the cylinder, and the fire service via 112 if there's any fire.
One more thing people rarely check before something happens: the home fire insurance policy. Standard Indonesian fire policies usually cover fire, lightning, explosion, falling aircraft, and smoke, but confirm the word "explosion" is in yours. And if you're thinking about dropping cylinders altogether, the numbers are in our piece on induction versus LPG cooking.
Frequently asked questions
How do I check for an LPG leak without special tools?
With the gas open and the stove off, brush soapy water on the valve-regulator joint, along the hose, on both clamps, and at the stove inlet. A growing bubble marks the leak.
Why shouldn't I turn on a light if I smell gas?
Switches and plugs can throw a tiny spark. LPG is heavier than air and pools near the floor, so a small spark in that room can ignite it. Open the doors and windows first.
How often should the hose and regulator be replaced?
Common manufacturer advice is about two years for the hose and five for the regulator, or per the packaging. Replace sooner if the hose is stiff, cracked, or discoloured. Choose SNI-marked parts.
