The Growing Concerns of Plastic Waste and the Emergence of Biodegradable Plastics

In today's world, plastic has become an integral part of our daily lives. From simple household items to sophisticated technology, plastic is used extensively. However, this widespread use of plastic has raised significant concerns related to its negative impact on the environment. The handling of plastic waste is currently carried out through various methods, including recycling, incineration, and burial (landfill). Burning plastic waste poses a risk of producing toxic substances that are harmful to living organisms, while burial is not effective due to the long degradation time of plastic.

The Need for Biodegradable Plastics

In an effort to overcome the problem of plastic waste, biodegradable plastics have emerged as a promising solution. One type of biodegradable plastic that is being developed is lactic acid poly (PLA), which can be produced from dextrose raw materials using lactobacillus delbrueckii bacteria. The production of PLA has gained significant attention in recent years due to its potential to reduce plastic waste and mitigate its negative impact on the environment.

The Factory Design and Production Capacity

The factory design to produce PLA has a production capacity of 15,000 tons per year, assuming operational for 350 working days a year. This production capacity is expected to meet the growing demand for biodegradable plastics and contribute to the reduction of plastic waste. The factory is planned to be established in the Sidoarjo area, East Java, with an area of 20,000 m².

Organizational Structure and Human Resources

To run factory operations, 153 workers are needed, and will be in the form of a Limited Liability Company (PT) business entity led by a President Director with the organizational structure of the line system. This organizational structure is expected to ensure efficient and effective management of the factory operations.

Economic Analysis

The results of the economic analysis show that the lactic acid poly-making factory is very feasible to be established. The following are the details of economic analysis:

Total investment capital: Rp. 210,897,576,652,-
Production Costs: Rp. 453,183,835,546,-
Sales proceeds: Rp. 570,857,873,534,-
Net profit: Rp. 190,940,743,256,-
Profit margin: 20.51%
Break even point: 51.54%
Return on Investment: 22.29%
Pay out time: 4.49 years
Return on Network: 37.15%
Internal Rate of Return: 34.01%

From these data, we can see that the net profit generated is quite significant, which indicates that the income received exceeds production costs. The profit margin of 20.51% shows good cost efficiency, while the break even point of 51.54% indicates that the factory will soon return capital in a relatively short time.

Environmental Benefits

Not only from the economic aspect, but the manufacture of lactic acid poly also has a positive impact on the environment. As a biodegradable plastic, PLA can be degraded naturally and reduce the amount of plastic waste that pollutes the environment. Thus, the existence of this factory not only provides economic benefits but also an important step in reducing the adverse effects of plastic waste.

Conclusion

Based on the results of economic analysis and positive environmental impact, it can be concluded that the establishment of the lactic acid poly-making factory from Dextrose in Sidoarjo is a project that is very feasible to do. This investment not only has the potential to provide financial benefits but also contributes to global efforts to reduce the problem of plastic pollution. With the continuing development of technology and public awareness of the importance of the environment, this factory is expected to be part of the solution for the challenges faced today.

Recommendations

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

The government should provide support and incentives for the establishment of biodegradable plastic factories, such as tax breaks and subsidies.
The public should be educated about the importance of biodegradable plastics and the benefits of reducing plastic waste.
The industry should continue to develop and improve the production of biodegradable plastics, such as PLA, to meet the growing demand and reduce plastic waste.

Future Research Directions

Future research directions include:

Conducting a detailed feasibility study of the factory design and production capacity.
Conducting a thorough analysis of the environmental impact of the factory operations.
Developing new technologies and processes to improve the production of biodegradable plastics.

Limitations of the Study

This study has several limitations, including:

The study is based on a single case study of a factory design and production capacity.
The study does not consider the social and cultural impacts of the factory operations.
The study does not consider the potential risks and challenges associated with the production of biodegradable plastics.

Conclusion

In conclusion, the establishment of a lactic acid poly-making factory from Dextrose in Sidoarjo is a project that is very feasible to do. This investment not only has the potential to provide financial benefits but also contributes to global efforts to reduce the problem of plastic pollution. With the continuing development of technology and public awareness of the importance of the environment, this factory is expected to be part of the solution for the challenges faced today.
