Summary: Liquefied petroleum gas tanks are commonly used in kitchen households due to their affordable price and availability. Based on the Bureau of Fire Protection (BFP) reports, there are several cases where these gas tanks cause house fires. There are existing devices in the market that are capable of detecting gas leaks, sending SMS notification, and monitoring the gas level. However, these devices cannot detect abnormal levels of gas pressure, which is also an indication of leakage in gas. The researchers raised an idea to design, develop, test, and evaluate a gas leak detection with an SMS notification system to prevent fire in households. The system is composed of an MQ-6 sensor for gas detection, a pressure transducer sensor for the air pressure, a solenoid valve to cut the flow of the gas in the hose, a GSM module, and implemented through waterfall methodology. Results show that there is no significant difference in the time behavior of the MQ-6 gas sensor (F(3,36) = 0.446, p = 0.722) and pressure transducer sensor (F(3,36) = 0.753, p = 0.528) toward the activation of the shut-off valve. This means that the system can consistently shut off the valve immediately after the two sensors detected a high level of gas and pressure from the LPG. Meanwhile, the system was evaluated based on the ISO 25010:2011 standard quality system with the following criteria, such as performance efficiency, reliability, maintainability, and portability. Overall, the respondents rated the prototype with an average of 3.89 or “Strongly Agree” that the system meets quality attributes. This research is aligned with the UN-SDG 11 for sustainable cities and communities.

Liquefied petroleum gas tanks are commonly used in kitchen households due to their
affordable price and availability. Based on the Bureau of Fire Protection (BFP) reports,
there are several cases where these gas tanks cause house fires. There are existing devices
in the market that are capable of detecting gas leaks, sending SMS notification, and
monitoring the gas level. However, these devices cannot detect abnormal levels of gas
pressure, which is also an indication of leakage in gas. The researchers raised an idea to
design, develop, test, and evaluate a gas leak detection with an SMS notification system to
prevent fire in households. The system is composed of an MQ-6 sensor for gas detection,
a pressure transducer sensor for the air pressure, a solenoid valve to cut the flow of the gas
in the hose, a GSM module, and implemented through waterfall methodology. Results
show that there is no significant difference in the time behavior of the MQ-6 gas sensor
(F(3,36) = 0.446, p = 0.722) and pressure transducer sensor (F(3,36) = 0.753, p = 0.528)
toward the activation of the shut-off valve. This means that the system can consistently
shut off the valve immediately after the two sensors detected a high level of gas and
pressure from the LPG. Meanwhile, the system was evaluated based on the ISO
25010:2011 standard quality system with the following criteria, such as performance
efficiency, reliability, maintainability, and portability. Overall, the respondents rated the
prototype with an average of 3.89 or “Strongly Agree” that the system meets quality
attributes. This research is aligned with the UN-SDG 11 for sustainable cities and
communities.
