ABSTRACT
Article history:
This study analyzes the economic feasibility of implementing integrated energy systems in industrial areas in Indonesia.
Using a quantitative approach, data was collected from 35 industrial areas through a Likert scale survey, and analyzed using SPSS version 26.
The analysis focused on key variables such as investment costs, energy savings, payback period, government support, technical feasibility, and energy efficiency.
The results revealed that while energy savings and government support were perceived as key benefits, high investment costs and long payback periods posed significant barriers to adoption.
Additionally, the findings highlighted a strong correlation between technical feasibility and energy savings, underscoring the importance of infrastructure compatibility.

INTRODUCTION
The rapid industrialization of Indonesia has led to a significant increase in energy demand, particularly within the manufacturing sectors, necessitating the development of integrated energy systems that blend renewable and conventional sources to ensure sustainability and energy These systems are crucial for optimizing energy use, reducing dependency on non-renewable sources, and minimizing environmental impact, aligning with global The Indonesian government has set an ambitious target of achieving 100% renewable energy by 2060, with solar photovoltaic (PV) expected to 3% of the total installed capacity by 2050 .
A prominent example of renewable energy integration is the deployment of solar power plants combined with battery energy storage systems in Pulau Bunyu, which, despite high upfront costs, demonstrates potential for lowering fossil fuel consumption and increasing energy reliability .
Nonetheless, several challenges persist, including high initial investment costs, limited technological capabilities, and a shortage of skilled labor in renewable energy technologies .
Addressing these barriers requires robust policy support, financial Journal homepage: https://wsj.

Smart grid infrastructure and digital technologies offer promising avenues for enhancing energy flexibility, costefficiency, and system reliability, while the inclusion of diverse renewable sources such as biomass and geothermal further strengthens the resilience of IndonesiaAos energy infrastructure .
In practice, sectors like the cement industry, which is one of the largest industrial energy consumers, have energy-efficient strategies, although these measures have yet to significantly curb carbon emissions, underscoring the urgency for more effective, integrative energy solutions .
IndonesiaAos energy demand is projected to rise sharply by 2060, driven primarily by the expansion of industrial manufacturing sector, which is expected to retain a 34% share of the nationAos total energy consumption (Liun et al.
, 2.
As a major energy consumer, the industrial sector faces mounting pressure to adopt energy-efficient practices to mitigate both financial burdens and environmental degradation caused by continued reliance on fossil fuels .
response, renewable energy sourcesAisuch as solar, wind, and biomassAihave been actively promoted as part of IndonesiaAos long-term sustainability agenda aimed at reducing greenhouse gas emissions and ensuring energy security .

This is particularly critical in high-consumption industrial zones where managing energy supply and demand is inherently complex.
address these issues, the Indonesian government continues to develop policy frameworks aimed at accelerating the renewable transition by increasing the share of renewables in the national energy mix while balancing environmental goals with the need for sustained economic growth .

The Indonesian government has recognized the importance of transitioning to sustainable energy systems and has introduced policies to promote renewable energy adoption, including tax incentives, subsidies, and infrastructure development.
However, the economic feasibility of implementing integrated energy systems remains a key consideration for industrial The challenges of upfront investment, infrastructure upgrades, and uncertainty around long-term returns on investment often discourage industries from transitioning to integrated energy solutions.
This study seeks to analyze the economic feasibility of implementing integrated energy systems in industrial areas in Indonesia.
