Pre-design Factory Manufacturing Dextrin from Cassava Skin: A Feasibility Study

Introduction

The production of dextrin from cassava skin is a promising industry in Indonesia, with a growing demand for this versatile carbohydrate. In this study, we present a pre-design factory for manufacturing dextrin from cassava skin using an enzymatic hydrolysis process, with a production capacity of 13,000 tons per year. Our analysis shows that this factory is economically viable, with a net profit of Rp. 186,879,781,544,09 and a profit margin of 55.54%. In this article, we will discuss the process and engineering design of the factory, as well as its potential impact on the community and the environment.

Process and Engineering Design

The enzymatic hydrolysis process is a crucial aspect of this factory, as it uses specific enzymes to break down polysaccharides in cassava skin into simpler dextrin. This process is more efficient and environmentally friendly compared to other chemical methods, which often use acids or corrosive bases. The detailed technical design for the evaporator is also an important part of the Dextrin Purification process, as it is designed to remove water from dextrin solution to produce a concentrate final product. Energy efficiency is a priority in this design, by utilizing the heat produced during other processes in the factory.

Economic Analysis

Our economic analysis shows that the total investment capital needed for this factory is Rp. 356,470,535,809.79, with a total production cost of Rp. 228,595,783,995,62. Income from sales is estimated to reach Rp. 517,420,339,920, resulting in a net profit of Rp. 186,879,781,544,09. The factory profit margin is 55.54%, and the Bre-Event Point is achieved at 28.05%. Return on Investment (ROI) of 52.438% and pay-out time (pay-out time) around 1 year 9 months. In addition, Return on Network (RON) reached 87.38%, and the Internal Rate of Return (IRR) of 66.25%. These data indicate that the factory making dextrin from cassava leather is feasible to be established.

Socioeconomic Impact

From a socioeconomic point of view, this factory is expected to have a positive impact on the community. With the factory, open employment opportunities for 150 people, contribute to reducing unemployment, and improving the local economy. The use of cassava skin as a raw material also indicates the use of sustainable natural resources. Cassava skin is often considered waste, but with this factory, the waste can be utilized optimally, thus supporting the concept of circular economy.

Conclusion

In conclusion, the pre-design factory for manufacturing dextrin from cassava skin using an enzymatic hydrolysis process is a feasible project. The economic analysis shows that the factory is economically viable, with a net profit of Rp. 186,879,781,544,09 and a profit margin of 55.54%. The factory also has a positive impact on the community, by providing employment opportunities and utilizing sustainable natural resources. As a further step, it is important to carry out a deeper feasibility study and plan marketing aspects so that the products produced can compete in the market.

Recommendations

Based on our analysis, we recommend the following:

Conduct a deeper feasibility study to assess the potential of the factory and identify potential risks and challenges.
Plan marketing aspects to ensure that the products produced can compete in the market.
Implement the enzymatic hydrolysis process and detailed technical design for the evaporator to ensure efficient and environmentally friendly production.
Utilize the waste from cassava skin to support the concept of circular economy.

Q&A: Pre-design Factory Manufacturing Dextrin from Cassava Skin

Introduction

In our previous article, we presented a pre-design factory for manufacturing dextrin from cassava skin using an enzymatic hydrolysis process, with a production capacity of 13,000 tons per year. In this article, we will answer some of the frequently asked questions about this project.

Q: What is dextrin and why is it important?

A: Dextrin is a type of carbohydrate that is derived from starch. It is a versatile ingredient that is used in various industries, including food, pharmaceuticals, and cosmetics. Dextrin is important because it has a wide range of applications, from thickening agents in food products to excipients in pharmaceuticals.

Q: What is the enzymatic hydrolysis process, and how does it work?

A: The enzymatic hydrolysis process is a method of breaking down starch into dextrin using enzymes. This process is more efficient and environmentally friendly compared to other chemical methods, which often use acids or corrosive bases. The enzymes used in this process are specifically designed to break down the starch molecules into smaller dextrin molecules.

Q: What are the benefits of using cassava skin as a raw material?

A: Cassava skin is a waste product that is often discarded. However, it can be used as a raw material for dextrin production. The use of cassava skin as a raw material has several benefits, including reducing waste, conserving natural resources, and supporting the concept of circular economy.

Q: What is the production capacity of the factory, and how will it meet the demand for dextrin in Indonesia?

A: The production capacity of the factory is 13,000 tons per year. This is expected to meet 80% of the demand for dextrin in Indonesia. The remaining 20% will be met by imports from other countries.

Q: What is the economic analysis of the factory, and how will it generate revenue?

A: The economic analysis of the factory shows that it will generate revenue through the sale of dextrin. The total investment capital needed for the factory is Rp. 356,470,535,809.79, with a total production cost of Rp. 228,595,783,995,62.
