Abstract

Unstable temperature or being outside the control temperature of a sample will cause a change in the quality of the sample itself. The purpose of this study was to create a temperature control system on waterbath with fuzzy logic using 7 labels. Used the DS18B20 sensor as a temperature sensor, a processor in the form of an UNO arduino, a thermostat as part of safety control, and displayed on a 16x4 LCD. Temperature selection between 30°C-60C. Design research using pre-experimental methods with one type group of post-testing design research, by comparing modules with comparison tools in the form of digital thermometers. The results of the research in the manufacture of waterbath tools were conducted compared to the results of measurements in the room with a digital thermometer. Obtained the highest Error value of 0.91% at 35 °C and the lowest error of 0.049% at 60 °C. While the error value based on the setting temperature obtained the highest error value at the temperature setting of 30°C of 1.38% and the lowest error at the temperature setting of 60 °C of 0.05%. The average time required to reach the shortest setting temperature in the temperature range is 27°C-30°C for 193 seconds, and the longest time in the temperature range is 27°C-60°C for 2257 seconds. the results showed that the fuzzy method is better compared to conventional methods. The results of this study can be implemented for waterbath temperature control system to get more stable results in maintaining setting temperature.

Abstract

Temperature or temperature is an indicator of the degree of heat of an object. Cold chain or cold chain is a supply chain system that considers the temperature level in the process. Cold chain to keep frozen or chilled products in an environment with a certain temperature during production, storage, transportation, processing and sales. This is intended to maintain product quality. The purpose of this study was to determine the temperature distribution in the Blood bank at UDD PMI Surabaya City which was used for storage of blood products. By using the ESP32 system and the DS18B20 temperature sensor which will then be monitored via IoT, it will make it easier for users to monitor. The results of these measurements will be stored in a micro SD card for analysis. The data is processed by Non-Parametric Test resulting in an interpretation that the temperature of each shelf is different due to the difference in the location of the sensor placement. The temperature difference is also influenced by the pattern of use and the process of heat transfer from the bottom to the top of the shelf. This research was considered successful with the result of the highest temperature distribution being 3°C and the lowest being 2°C. The location of these racks can be useful in determining day-to-day monitoring measuring points. This value has met the standard for storage of blood products, which is in the range of 2°C-6°C.
