| dc.description.abstract | Silica flour is an inorganic compound whose main components are Silicon (Si) and Oxygen (O2). Bagasse ash has a high silica content that can be utilized into silica flour through the sol-gel process. The main objective in designing this factory is to implement the discipline of chemical engineering and to be the initial information in designing a silica flour manufacturing plant from bagasse ash through the sol-gel process with a capacity of 40,000 tons/year. The main process in this factory pre-design consists of four stages, namely the raw material preparation stage, the product formation stage, the product purification stage, and the product storage stage. The silica flour manufacturing plant from bagasse ash through the sol-gel process is planned to be established in Kesamben, Jombang Regency, East Java Province with a land area of 15,625 m2, the required workforce is 147 people in the form of a Limited Liability Company (PT) business entity led by a director with a line and staff organizational system. For the establishment and operation of the factory requires investment capital of Rp 3,421,455,353,759 and production costs of Rp 3,784,848,394,884. Based on the economic feasibility analysis, this factory has a PM of 20.009%, BEP of 43.070%, ROI of 19.335%, POT for 5.2 years, RON of 48.388%, and IRR of 22.227%. From the results of the economic analysis, it can be concluded that the pre-design of the silica flour factory from bagasse ash through the sol-gel process is feasible to be established. | en_US |
