Abstract

One of the innovation programs of the Sukamanah Village Karangtengah Cianjur farmer group is in the field of fisheries. One of the programs carried out is the nursery for ornamental Koi fish. Nursery of Koi fish is done because the market demand for Koi fish is high, but there are still very few Koi fish providers. However, farmer groups are currently unable to determine the number of seeds that must be provided to meet market needs to obtain maximum profit. To overcome this, a system is required that can calculate the number of seeds needed based on fish supply and market demand. Fuzzy logic can help humans make decisions; besides, fuzzy logic is an appropriate way to map an input space into an output space. This research aims to build an application using fuzzy logic to determine the number of seeds needed based on the amount of supply and market demand for Koi fish. The data used is sourced from the Sukamanah Farmer’s group, Cianjur. The results showed that using fuzzy logic succeeded in predicting the number of koi fish seeds that must be provided with an accuracy rate of 94,78% using the MAPE method.

Abstract

In this research, the design and manufacture of a prototype for a monitoring and watering system that integrates the concept of fuzzy logic in chili plants are carried out. The relationship between air humidity, air temperature and soil moisture can be identified to determine the right volume of water. The fuzzy system is built based on the chili farming environment and the specifications of the installed water pump. This system uses NodeMCU ESP8266 as the main controller for fuzzy inference calculations. The fuzzy inference calculation process uses the Mamdani method. Information such as air humidity, air temperature, soil moisture and water level will be displayed in real-time on the Blynk application connected to the internet network. The process of watering chili plants in this system is carried out according to a predetermined schedule. Results for seven days showed that the average duration of watering plants was 3.96 seconds with a flow rate ± 43.12 ml/s. By considering the maximum volume of the fuzzy system, the water consumption can be reduced with 30.96% efficiency.
