Plant Computational Modelling of Green Amaranth Plant for Investment Analyst using FSPM-GroIMP and Fuzzy Logic

Functional-Structural Plant Modelling (FSPM) isplant modeling that considers morphology, physiology, and statistical data. Oneof the software for FSPM is Growth-Grammar Interactive Platform (GroIMP).GroIMP a Java-based platform using XL language, which languagedeveloped from System-L. This study aims to build virtual plant model ofgreen amaranth (Amaranthus Sp.) in hydroponic planting systemfor strategic decision-making. In this study, parameter analysis modeldevelopment were carried out. The divided into two sub-model blocks byoperating three methods. There are sub-models, namely virtualplant, fuzzy logic. usingmathematical FSPM-GroIMP methods, results of arethe growth pattern green harvest, weight amaranth,and visualization plants. comparison, thesub-model logic uses method predict selling priceof plants expenses. sub-models combined produce hydroponicgreen decisions. output decisions adecision has an impact on investment value. value ismeasured by CR Ratio, comparing costwith revenue amaranth. Other showed theaverage single 11.85 g RC ratiovalue 4.5 500 with good quality, fixed cost IDR30,000,variable IDR20,000 price IDR57,282 per kilogram.Calculations verification validation out andindicated built according existing theory had correctvariable values.
