PRA Design of the Biogas Making Factory from Medan City Organic Waste

The increasing need for renewable energy and sustainable waste management has led to the development of innovative solutions, such as biogas manufacturing factories. In this article, we will discuss the design of a biogas making factory from Medan City organic waste with a capacity of 150,000 tons/year, utilizing an anaerobic digestion process and a specially designed anaerobic reactor.

Location and Capacity

The planned biogas manufacturing plant will be located in Medan Sunggal, Deli Serdang Regency, North Sumatra Province. The factory is designed to produce biogas from organic waste with a capacity of up to 150,000 tons per year. This capacity is significant, considering the operating hours of 1 hour per day and 330 working days in a year. The factory has the potential to contribute significantly to the management of Medan City Waste.

Anaerobic Reactor Technical Design

As part of this pre-design, a special task has been performed on the design of the anaerobic reactor. The designed reactor has the following specifications:

Construction material: Stainless Steel SA-167, Grade 10 Type 310
Type: Torispherical Dished Head
Tank volume: 80,647.9 m³
Tank diameter: 648.06 m
Tank height: 1296 m
Plate thickness: 2.53 in

This reactor is designed to maximize the efficiency of the digestive process and produce good quality biogas. The chosen construction material is stainless steel, which has a high resistance to corrosion and durability, making it suitable for anaerobic processes.

Biogas Factory Economic Analysis

This factory will operate as a limited business entity (PT) led by a President Director with the organizational structure of the line system. In this plan, the number of workers needed is 212 people. The results of the economic analysis of the biogas manufacturing factory showed several important points:

Investment Capital: Rp. 551,426,171,762,-
Production Costs: Rp. 353,630,543,270,-
Net profit: Rp. 370,087,557,032,-
Profit margin (profit margin): 30.488%
Break even point: 41,855%
Return on Investment: 20.165%

From this analysis, it appears that this biogas factory has a promising potential. High profit margin shows that this factory will not only be a solution to waste management, but also as a source of sustainable income.

Benefits and Contributions of Biogas Factory

The establishment of the biogas manufacturing factory is expected to provide multiple benefits. First, this factory will contribute to more efficient city waste management by converting organic waste into renewable energy sources. Second, this factory can also provide jobs for local communities, which in turn will improve the regional economy.

With the increasing need for renewable energy and better waste management, this biogas manufacturing factory has the potential to become a model for similar initiatives in other cities in Indonesia. It is hoped that this step will not only support environmental efforts, but also encourage sustainable economic growth.

Conclusion

The design of the biogas making factory from Medan City organic waste with a capacity of 150,000 tons/year is a significant step towards sustainable waste management and renewable energy production. The specially designed anaerobic reactor and the economic analysis of the factory show promising results. The establishment of this factory is expected to provide multiple benefits, including efficient city waste management, job creation, and sustainable economic growth.

Recommendations

Based on the results of this study, the following recommendations are made:

Implementation of the biogas manufacturing factory: The biogas manufacturing factory should be implemented as soon as possible to contribute to the management of Medan City Waste and provide jobs for local communities.
Monitoring and evaluation: Regular monitoring and evaluation of the factory's performance should be conducted to ensure that it operates efficiently and effectively.
Expansion of the factory: The factory's capacity should be expanded to meet the increasing demand for renewable energy and sustainable waste management.

By following these recommendations, the biogas manufacturing factory can become a model for similar initiatives in other cities in Indonesia and contribute to the country's sustainable development goals.
