“…Quantitative analysis was used to explain the cost and return of cassava flour production as well as its feasibility. The components of economic feasibility analysis for cassava flour production included mass balance analysis to determine the amount of incoming materials compared to materials coming out of the cassava flour processing (Mustafa, 2015), revenue (Sriyadi et al, 2021), production cost (C) (Ojiako et al, 2018), net income (I) or profit (Ojiako et al, 2018), revenue cost ratio to determine the profitability or the efficiency of flour production (Elisabeth & Prasetiaswati, 2018;Gustina et al, 2020), net profit margin (NPM) to measure the ratio of net income to sales (Pangestu et al, 2015), return of investment (ROI) (Walyupin et al, 2018); and payback period (PP) which indicates the period of time during the investment to get an overall return (Stelling et al, 2018).…”
