Prototype Monitoring Suhu Berbasis Mikrokontroler Pada Cool Box Ikan Menggunakan Sensor DS18B20 Dengan Metode Fuzzy

Abstract

Often fish supply in to the consumers need long relatives distance and much time. Meanwhile the consumers always want fresh fish. The problem occurred was broken stock of fresh fish in every shipping and happened almost all the time. It made fish became stale and made supplier got lose. The study was took place in Batulicin Simpang Empat in a harbor (Pelelangan Pembongkaran Ikan) until now the handling of fish catches generally used ice block in the usual cool box. Using ice block is one of easiest method. Although, using ice block only could maintain low temperature in short time whereas the ideal temperature of cool box should be 10 ͦ Celsius measured by usual temperature’s device room. In shipping process, the driver unpack the cool box to checked temperaturemanually. This matter waste time and cost because the driver should provide extra ice block to maintain low temperature of cool box. In order to resolve the problem, monitoring could be done automatically by using a microcontroller chip in the cool box with DS18B20 censor and fuzzy methodbase microcontroller. The purpose was supplier could be helped to monitoring the stabilities of cool box temperature used website. This system is made by computerization. It would make supplier job easier because driver able to check fish condition without unpack the cool box and made time, energy and cost more efficient.
