The Indonesian government plans to phase out the circulation of 3-kilogram (kg) liquefied petroleum gas (LPG) cylinders. As a replacement, the government will distribute free induction cooktops to communities in several regions.
"The circulation of 3 kg LPG will be gradually reduced in areas where induction cooktop packages have been distributed," said the Acting Director General of Electricity, Dadan Kusdiana, as reported by *Katadata.co.id* on Thursday (September 15, 2022).
"PLN is tasked with conducting a pilot program for the conversion from 3 kg LPG stoves to induction cooktops in 2022 in Solo City, Central Java, and Badung Regency, Bali. Each will provide 1,000 beneficiary families with free cooktops," he continued.
Dadan explained that each household will receive one induction cooktop with two burners, each with a capacity of 1,000 Watts. This will be accompanied by two cooking utensils: a pot and a frying pan, equipped with an Internet of Things (IoT) module to record electricity consumption data.
Comparing the Efficiency of Induction Cooktops and LPG
According to a research report, *Mega Conversion from LPG to Induction Stove to Achieve Indonesia's Clean Energy Transition*, written by Dzikri Firmansyah Hakam et al. (May 2022), induction cooktops have varying efficiencies depending on their wattage.
The efficiency level in this report is measured based on the time and cost required to boil 1 liter of water from 30°C to 100°C.
The report notes that to boil 1 liter of water, an LPG stove takes 231.2 seconds and costs US$0.0113 or approximately Rp169.25 (using an exchange rate of Rp14,978 per US$).
Meanwhile, a 1,800-Watt induction cooktop takes 219.8 seconds and costs US$0.0106 or approximately Rp158.77, slightly cheaper than LPG.
"The research results show that the 1,800-Watt induction cooktop has the best energy efficiency (81.78%) compared to other types of cooktops," the report states.
However, induction cooktops with lower power ratings, namely 1,400 Watts, 1,000 Watts, and 500 Watts, take longer to boil water than LPG stoves.
The cost of boiling water with lower-powered induction cooktops is also not significantly different from LPG stoves; in some cases, it is even more expensive, as shown in the graph.
"However, the results of this research depend on the power class of the cooktop. The energy efficiency of the cooktop certainly affects the cost and time required for cooking," the report clarifies.
