Abstract: Stove is a cooking utensil for households to provide food to meet daily needs. LPG gas stoves are very

commonly used by various groups because they’re easy to buy and in terms of prices are very affordable

because of subsidies from government which makes gas prices very affordable because government still

provides subsidies for LPG for 3-kilogram. The government is now encouraging the Import-Based Energy

Transfer Program into Domestic-Based Energy through the Conversion of LPG Stoves to Induction Stoves to

support National Energy Security, and the conversion of LPG stoves to Induction cookers as one of the

strategies to reduce LPG imports. In previous studies, the performance of gas stoves and induction cookers

was tested, comparing energy consumption and economic aspects by testing them in boiling 1 liter of water.

From the results of research on technical aspects, it states that an induction stove can replace a 3-kilogram

LPG stove, the use of an induction cooker with a 2-burner design (1,000 Watt and 1,800 Watt), cooking costs

are more efficient Rp. 45,770/month for the power group of 450VA and Rp. 30,190/month for 900VA power

group households. The economic aspect has an impact on reducing LPG imports to meet national energy

needs.

1 INTRODUCTION

Stoves are daily necessities that are used by the

community as a tool to provide various foods to meet

basic needs. The use of gas stoves is very commonly

used by various groups because they are easy to buy

and in terms of cost are very affordable due to

subsidies from the government which causes gas

prices to be very affordable (Pawenary, 2020).

In Indonesia's efforts towards the transition of Net

Zero Emmision and supporting environmentally

friendly campaigns, the Government is now

encouraging the Transfer of Import-Based Energy to

Domestic-Based Energy through the Conversion of

LPG Stoves to Induction Stoves to support National

Energy Security, and the conversion of LPG stoves to

Induction stoves is one of the strategies to reduce

LPG lmpor tubes of 3 kg, which began with through

the movement of 1 million induction stove users in

2021 and starting in 2022, it will increase by 2 million

/ year so that it reaches 18.2 million induction stove

users in 2030. The Government's strategy in the LPG

stove conversion program to Induction stoves in

addition to aiming to save lpg import costs is also to

save significant LPG subsidies, because LPG

consumption in the household sector (LPG stoves)

has a portion of almost 96% of the total national LPG

consumption.

Based on the description above, it is necessary for

researchers to answer the problems mentioned above

through the analysis of technical aspects and

economic aspects of electrical energy consumption in

the induction stove program so that the public can

know the differences and advantages of using these

stoves.

This research will be conducted to compare and

the benefits of induction stoves and gas stoves such

as the amount of energy consumption and the costs

required in their use.

2 METHODOLOGY

The testing methods that will be carried out in this

study are as follows:

a. Heating water from temperature ± 20 °C to ±

90 °C;

b. Water mass weighing ± 2500 grams;

The stages of testing that will be carried out in this

study are as follows:

a. Induction stove measurement data collection

includes maximum power setting, maximum

rated power, time, energy consumption,

conversion, efficiency during the discharging

of the induction stove;

the mass of gas (before and after use) to

determine the magnitude of the amount of heat

used and data on time changes; and

2.1 Equations Used in the Study

2.1.1 Effort or Electrical Energy

Effort or electrical energy can also be expressed in the

following, equation:

W = V.I.t (1)

Where:

I = Strong electric current (amperes)

V = Potential difference (volts)

t = time (second)

W = Electrical effort or energy (Watt.second or Joule)

2.1.2 Thermal Energy (Heat)

If a substance or object undergoes a change in shape

or form at a fixed temperature, a certain amount of

heat is needed in the process. The magnitude of the

required amount of heat can be expressed in the

following equation:

Q = m.L (2)

Where:

Q = Amount of heat released or absorbed (Joule)

m = Mass of an object or substance (kg)

L = The amount of heat released/absorbed any change

in the shape or form of a substance per unit mass or

can also be referred to as Heating Value (Joule/Kg).

2.1.3 Efficiency

Efficiency is calculated by comparing the heat

transfer with the use of real heat.

Q = m x cp x T (3)

Where:

Q = Heat needed or released

M = mass

Cp = calorific type of substance

∆T = the difference between the initial temperature

and the final temperature.

3.3 Average User of Subsidized

Household Induction Stove

Data on the average household cooking per day 2-

furnace induction stove is 2 hours on per day (ESDM,

2022).

So the data on the average monthly use of an

induction cooker for cooking are: (2 JN x 1,8 kw x 30

days x 0,76) = 82 kWh. Where: 1.8 kw is the optimal

power capacity of induction cooker discharging 2

furnaces.

3.4 Comparison of Energy Use Results

Gas Stoves on Customers of 450 VA

Power and 900 VA Power

The comparison results of the calculation of energy

consumption and costs on induction stoves and gas

stoves on customers of 450 VA power and 900 VA

power are shown in the following table.

4 CONCLUSIONS AND

SUGGESTIONS

Based on the research that has been carried out, it can

be concluded that:

The use of induction stoves with a design of 2

furnaces (1,000 Watts and 1,800 Watts) (ESDM,

2022), then:

a. The cost of cooking with an induction cooker is

IDR 45,770/month for a household with a 450

VA power group compared to using a 3

kilogram tubes gas stove with liquefied

petroleum gas; and

b. The cost of cooking with an induction cooker is

IDR 30,190/month for a household with a power

of 900 VA power group compared to using a 3

kilogram liquefied gas fuel stove;

The use of energy on induction stoves can replace 3

kilogram tubes LPG gas stoves, this is from the

iCAST-ES 2022 - International Conference on Applied Science and Technology on Engineering Science

882

results of research to save subsidies compared to 3

kilogram LPG, then:

a. The cost of cooking with an Induction Cooker

can save more in subsidies of IDR.

47,310/month for 450 VA power group

households; and

b. The cost of cooking with an Induction Cooker

can save more in subsidies of IDR.

62,890/month for 900VA power group

households.
