Food Estate is a government program as a solution to meeting food demand. However,
in order to meet food needs, environmental impacts must be considered. The study objective was
to investigate the impacts of shallot production in Food Estate Hutajulu, Indonesia. The study
was conducted with the first stage determining the functional unit, namely an area of 0.2 hectares
with a gate-to-gate scope. The second is the inventory data analysis by grouping the categories of
nursery, tillage, maintenance, harvesting, and transportation. The third is life cycle impact
assessment (LCIA) according to the ISO 14044 standard. Every data obtained from each process
was processed using the software OpenLCA 1.11.0; the following is the workflow and use of the
software. Processes were made based on the five categories of data (soil processing, planting,
maintenance, harvesting and transportation), which had been determined to be connected to flow.
The product system was adjusted according to the data in each process and then calculated, and
the results of calculation data and graph models appear from each processed data category. Fourth
is the interpretation that considers the highest environmental impact, namely acidification in the
transportation process of 1.8974 kg SO2 eq, global warming potential in the transportation
process of 415.3188 kg CO2 eq, eutrophication in the transportation process of 0.4364 kg PO4 eq,
and human toxicity in the maintenance process of 1,409.07377 kg 1,4-DB eq. To minimize the
impact on subsequent production, reducing diesel fuel, chemical pesticides and chemical
fertilizers are recommended.
