    The purpose of this research was to analyze the production method of a membrane of silica nanoparticles from an economic perspective. Silica nanoparticles are synthesized using a coprecipitation method. Briefly, the process consists of immersion, heating, precipitation, washing and drying, and packaging. The parameters used for economic analysis are gross profit margin (GPM), internal rate return (IRR), payback period (PBP), cumulative net present value (CNPV), break-even point (BEP), and profitability index (PI). The production of this ultrafiltration nano-silica membrane can be done by varying the amount of initial sand from 6 to 14 kg. The production of ultrafiltration nano-silica membranes can be produced in both domestic and micro-scale industries. To get a very good profit, economic analysis shows the minimum amount of sand used should be more than six kg. This study is very important because the production of ultrafiltration nano-silica membranes have a high potential in the field of economics and will encourage further investigation for the possibility of industrial production of these ultrafiltration nano silica membranes.
