Lanthanum nickelate (La2NiO4) is a precursor for producing lanthanum pentanickel (LaNi5) alloys for nickel-metal hydride battery (NiMH; a type of rechargeable battery), which has been developed quite rapidly for many applications, such as Hybrid Electric Vehicles. The purpose of this study was to evaluate the economic feasibility of the production of La2NiO4 with different fuels (i.e., glycine fuel (F-G) and citric acid fuel (F-CA)) using a sol-gel combustion method. Several economic evaluation parameters were analyzed, such as gross profit margin, internal rate of return, payback period, cumulative net present value, and so on. The project was evaluated from the ideal condition to the worst-case conditions, including labor, sales, raw material, utility, as well as external conditions (e.g., tax). The results showed that the production of La2NiO4 is prospective from engineering and economic perspectives. The engineering analysis for both production steps using F-G and F-CA is feasible, and the production can be done even in small-scale production using commercially available apparatus. The economic analysis showed that the process using F-CA is better than that using F-G. From this economic evaluation analysis, the project is profitable and the recovery of the investment is less than seven years for F-G and four years for F-CA. Although this project is feasible to run and profitable, it is not attractive to industrial investors due to the fewer values in some parameters. Thus, since this material is very important to reduce dependence on imports, additional further technologies for improving processes and support from Corporate Social Responsibility (CSR) and government are important for maintaining this project.

<p><em>The purpose of this study is to determine the feasibility of the project to make Magnesium Oxide (MgO) sol gel combustion method by evaluating the engineering and economic aspects. Several economic evaluation parameters are analyzed to inform the potential production of MgO nanoparticles, the length of time required for an investment to recover the total initial expenditure (PBP), project conditions for a production in the form of a production function in years (CNPV), project profits and others. The results showed that the production of MgO nanoparticles was very prospective. Technical analysis to produce 1.38 kg of MgO nanoparticles per day shows the total cost of the equipment purchased was USD 91,542.86. PBP analysis shows that investment profitable after more than 3 years. This project can compete with PBP capital market standards because the investment will return in a short time. To ensure the feasibility of the project, the project is estimated from the ideal conditions to the worst cases in production, including labor, sales, raw materials, utilities, and external conditions (e.g. tax).</em></p>
