Sistem Penunjang Keputusan Penentuan Biaya Investasi Tanaman Hidroponik Menggunakan Fuzzy Tsukamoto

Abstract

Decision support system is a system used to support and help management make decisions in semi-structured and unstructured conditions. Hydroponics is a term used to explain some ways to grow crops without using soil as a medium for planting. The problem that occurs is that many people demand for vegetables to be consumed which causes farmers to be overwhelmed to offset these needs. Lack of public knowledge about hydroponic farming causes a lack of people who run this business. The design of the decision support system for determining the investment cost of hydroponic plants uses the Tsukamoto Fuzzy Logic method because the formulation and calculation of the Tsukamoto fuzzy logic system are very easy to understand, accurate and weighty in determining the value of the investment costs sought. The decision support system design method used is prototype. The modeling technique used in this decision suppot system is UML (Unified Modeling Language) because it is an object-oriented modeling method and focuses on defining static structures and dynamic information system models. The results of application testing can produce the optimal value of investment costs which is almost close to the Tsukamoto fuzzy interest. The weakness of this application is the level of accuracy of the system is only 35.8%, and the lack of determinants.
