Presentasi Sidang Prarancangan Pabrik Kimia Sodium Dodecylbenzene Sulfonate Kapasitas 40.000 Ton/Thn

Summary

In this presentation, Anggi Rasane Claresta discusses the pre-design of a factory for producing sodium dodecyl benzene sulfonate (SDBS) with a capacity of 40,000 tons per year. The need for this factory is driven by the increasing population and demand for detergents in Indonesia. The factory, to be established in Cilegon, Banten, will utilize local raw materials and provide economic benefits such as job creation and increased exports. The process involves several stages, including preparation, reaction, purification, neutralization, and drying. The economic analysis indicates that the project is viable and beneficial for the local economy.

Q & A

What is the title of the final project being presented?

The title of the final project is 'Preliminary Design of a Sodium Dodecylbenzenesulfonate (SDBS) and Sulfuric Acid Plant with a Capacity of 40,000 Tons per Year.'

Why is the establishment of the SDBS plant important?

The establishment of the SDBS plant is important due to the increasing population in Indonesia, which drives the need for environmental cleanliness. SDBS, a surfactant commonly used in detergents, plays a critical role in this. The demand for SDBS is expected to rise with the increased use of detergents, making the plant economically beneficial.

What raw materials are required for the production of SDBS in this plant?

The raw materials required for the production of SDBS are dodecylbenzene, sulfuric acid, and sodium hydroxide.

Where will the SDBS plant be located, and why was this location chosen?

The SDBS plant will be located in the Cilegon Industrial Area, Banten, Indonesia. This location was chosen because it is close to the suppliers of the raw materials: PT Unggul Indah Cahaya for dodecylbenzene, PT Indonesia Acid Industry for sulfuric acid, and PT Asahimas Chemical for sodium hydroxide.

What is the estimated production capacity of the plant, and how was this capacity determined?

The estimated production capacity of the plant is 40,000 tons per year. This capacity was determined based on factors such as import-export data, demand trends, and existing plant capacities, ensuring it is economically viable for both domestic use and export.

What are the key steps in the SDBS production process?

The key steps in the SDBS production process include raw material preparation, sulfonation reaction, purification, neutralization, and drying.

How will the plant's operations be managed in terms of organizational structure?

The plant will operate as a limited liability company (PT) with 160 employees. The organizational structure is headed by a Chief Executive Officer (CEO) or Managing Director, overseeing the plant's 24/7 operation throughout 330 days of the year.

What is the estimated financial investment required for this project?

The estimated financial investment required includes a fixed capital investment of 19 million US dollars and 78 billion Indonesian Rupiah, and working capital of 468 billion Rupiah.

What are the key financial indicators for the project's viability?

The key financial indicators include a Return on Investment (ROI) before tax of 38.93%, ROI after tax of 27.91%, a payback period before tax of 2.54 years, and after tax of 2.4 years. The project also has a break-even point of 48.54% and a shut-down point of 20.51%.

Is the project considered economically viable based on the analysis provided?

Yes, based on the economic analysis, including the ROI, payback period, break-even point, and discounted cash flow, the SDBS plant project is considered economically viable and worth further consideration.
