“…The temperature of the waterbath must be controlled with precision, because even small variations in temperature can affect the results of the experiment. Several techniques have been developed to control waterbath temperature, such as on/off control, proportional control, and PID control [1]. the introduction of the Shaking Water Bath module with automated water filling and draining, temperature detection using the LM35 sensor, and real-time display on a 4x20 character LCD represents a significant advancement in medical laboratory equipment.…”

“…Data collection is carried out using settings 30°C -60°C with 5x repetition at each temperature setting point in 4 different temperature sensors simultaneously to see the temperature value produced by the DS18B20 temperature sensor. The average value of the measurement is obtained using the mean or average by applying equation(1). The average is a number obtained by dividing the number of values by the amount of data in the set.…”

Water baths are commonly used in scientific fields to incubate samples at specific temperatures. The temperature of the water bath must be controlled precisely, because even the slightest temperature variation can affect the results of the experiment. It can handle imprecise, uncertain and incomplete information, making it suitable for temperature control in water baths. This research aims to determine the distribution and stability of fuzzy logic control to control the temperature of a water bath with four heaters. Even heat distribution from the four heaters will ensure consistent water bath temperature throughout the bath. This research uses an Arduino microcontroller to process the temperature sensor output from the DS18B20, then the processed temperature value will be displayed on the TFT LCD. The independent variable in this research is the temperature value, while the dependent variable is the DS18B20 temperature sensor. The largest error value from the module measurements is at a temperature setting of 30 ºC on the 2nd temperature sensor with an error value of 1.43%. Meanwhile, the smallest error value is found at a temperature setting of 35 ºC on the 1st and 4th temperature sensors with an error value of 0.01%. Data collection used a digital thermometer comparison tool with 10 repetitions as a temperature sensor reference tool. The results obtained using this sensor are more stable and have a high accuracy value. The results of the research show that the temperature difference between points 1 to 4 when viewed from the error percentage is very small, or it can be said that the temperature distribution is even. The conclusion from these results is that the module has a stable temperature value and the error value is low and is still within the tolerance limit. permitted is ±5%.

The existence of sophisticated equipment is always needed in the laboratory. Purpose is to support the laboratory and support the laboratory staff to work safely and comfortably. One tools commonly used in laboratory is waterbath. In this study, a microcontroller-based waterbath was designed which was equipped with time module for setting the heating time and buzzer as marker when the heating time was complete. In addition, this tool is also equipped with temperature settings from 400C - 950C. This research is an exploratory descriptive research The results of testing the waterbath tool show that the 5 minute time setting has an error percentage value of 3.5%, 10 minutes is 2.3%, 15 minutes is 0.05%, 20 minutes is 1.01%, 25 minutes is 0.001% and 30 minutes is 0.2%. Then the temperature test of 400C has a percentage error of 0.7%, 500C is 0.9%, 600C is 0.8%, 700C is 0.8%, 800C is 1.8%, 900C is 2.7% and 950C is 2.0%. In addition, this tool also meets the standard according to function with a size of 20x20x30cm which is ideal for operation.
