Liquefied Petroleum Gas (LPG) or more commonly known as LPG gas is a gas stove fuel
that comes from the results of liquefied petroleum gas and is then put into a tube, one of
which is a 3-kilogram tube. The behavior of dependence on the consumption of 3-kilogram
gas cylinders from the people of Banggai Regency can be seen from the use of non-
subsidized 3 kilogram LPG gas, namely (±) 32. 002 people/group, the second is the
consumption rate from subsidies and non-subsidies, namely 38. 864 units from total users,
namely (±) 45. 000 people/groups with a supply of 30. 800 units and the third about frequent
scarcity in 2020 and early 2021 reported by Banggai News and Obormotindok. Simulation
Method Dynamic systems are modeling and running simulations of real systems to analyze
problems and present solutions from policy scenarios from the researcher's perspective. By
using this method, researchers can identify the behavior of 3 kilograms of gas consumption
from the rate of consumption and demand through tables and graphs using the Powersim
Studio 7 software. The results of the study present 3 policy scenarios, namely the first
scenario regarding an increase in the transition to 99% non-subsidized gas cylinders with
simulation results, namely September 1 2021 - October 1 2022 the demand is fulfilled, the
second scenario regarding the addition of a 7th agent with simulation results, namely
September 1 2021 - April 1 2023 demand can still be fulfilled and the third scenario regarding
an increase in the transition to 99% non-subsidized gas cylinders and the addition of a 7th
agent with simulation results, namely 1 September 2021 – 1 September 2023 the demand for
needs is fulfilled. The conclusion is that the third policy scenario will be taken because among
the policy scenarios presented, the preparation of tube supplies is fulfilled within two years,
namely September 1 2021 - September 1 2023.
