One example of nanomaterials that are currently widely used is nickel oxide nanoparticles (NiO). These nanomaterials show many unique optical, electrical, magnetic and chemical properties [1]. NiO can be used in important applications such as catalysts, gas sensors, magnetic materials, electro chromic films, battery cathodes, and super capacitors [2-4]. Several methods have been developed by researchers for the synthesis of nickel oxide nanoparticles. Examples are the co-precipitation method [5], the sol-gel method [6], the green method [7], the reaction between nickel chloride and hydrazine [8], low pressure spray pyrolysis [9], the surfactant mediated method [10], the process simple liquid phase [11], complexation precipitation method [12] and other techniques [13-15]. Of the various methods, the co-precipitation method is the best method for producing NiO nanoparticles on an industrial scale. This method is easy to use because the raw materials used are easily available and inexpensive. In this study, we did research the industrial production process of NiO nanoparticles in terms of engineering and economic evaluation. The synthesis of existing NiO nanoparticles is only discussed for laboratory scale production. There is no information about economic evaluation on the industrial scale of NiO nanoparticles. Economic evaluation is very important because it is related to further studies to increase production. Economic evaluation of the chemical industry is a form of quantitative assessment of what is expected and desired by the community to carry out the investment process in a project [16]. To get a feasibility study, the data is calculated to get the maximum results of NiO fabrication that can be applied on an industrial scale. In addition, this research is important to help in making a decision whether the fabrication of NiO nanoparticles is profitable or not. Also, this study can be used to suggest ways to optimize projects and to benefit ARTICLE INFO ABSTRACT Article history Received November 11, 2019 Revised December 11, 2019 Accepted December 17, 2019 Nickel oxide (NiO) nanoparticles have been proven and can be used in a variety of important applications. The purpose of this research was to evaluate the production process of NiO nanoparticles using the industrial co-precipitation method in terms of engineering and economic evaluation. Specifically, research was conducted by varying raw materials, product selling prices (GPM), equipment prices, and number of employees, which are compared with several economic parameters such as total investment cost (TIC), gross profit margin (GPM), break even point (BEP), payback period (PBP), net present value (NPV), and cumulative net present value (CNPV). The results showed that the PBP analysis showed that the investment would be profitable after more than 4 years with minimum product sales (GPM) of at least 90% and an increase in the price of raw materials no more than 15% of the ideal price. From this economic evaluation analysis, we can conclude that this project is feasible to run. This is an open access article under the CC–BY-SA license.
