Abstract

Fruit spoilage during transportation is a major problem that results in significant economic losses for fruit producers and distributors. One of the primary causes of fruit spoilage is heat buildup inside the storage container during transportation. Hence, this study was done to design and develop an Arduino-based field heat regulator for fruit storage and transportation, regulate field heat in terms of temperature and humidity monitoring; and assess its influence in terms of the skin color, firmness, and bruising of the fruit specimen. After the conduct of the study, it was found that the regulator underwent several iterations during product development and was tried out in an actual transportation procedure. The results revealed that during transportation the product was subjected to fluctuations in temperature and relative humidity, but the storage regulated heat by maintaining desired conditions. Additionally, there was a significant difference found in terms of the fruit's quality parameters when transported using the proposed storage and the traditional method. In conclusion, this storage has the potential to be used in fruit storage facilities, helping reduce post-harvest losses and decrease the chances of fruits being spoiled easily.

Abstract

Global carbon dioxide (CO2) emissions are rising, and microalgae have been a primary focus for alleviating the negative impacts of increasing CO2 levels. CO2 sequestration is influenced by pH level, temperature, light, nutrient levels, and aeration. This study adapted a 2-chamber system with a 6-Liter vertical-column photobioreactor. It was constructed to remove CO2 from the air using microalgae. Arduino sensors, namely temperature, pH, and CO2 gas, were incorporated to monitor microalgal growth. Two 7-day trials, with an initial algae mass of 15 g, were implemented to investigate the growth and CO2 removal rates. The results showed that trial 1 yielded 21.5 g with a growth rate of 0.56 gxin-2 x day-1, and trial 2, a final sample of 19.7 g with a growth rate of 0.51 gxin-2 x day-1. The CO2 removal rate for trial 1 increased from 10.17% to 22.04%. However, the CO2 removal rate for trial 2 decreased from 15.66% to 3.55%. In terms of relative percent error, the Arduino sensors' accuracy was also determined to be low, ranging from 0.85 to 1.94. With accurate readings, the findings show that the CO2 removal efficiency rate and algae growth rate are directly proportional to each other.
