Abstract
Composting in an aerobic , or oxygen-driven process by which there is a presence of breaking down of organic materials by microorganisms under controlled conditions of ventilation, temperature and moisture (Dissanayaka et al.., 2021) As it undergoes in a process that is enabled by aeration interaction, the temperature indicates the level of degradation or microbial activity happening within a compost pile (Yuan et al., 2018) whereas the supporting moisture content increases the potential of increasing and prolonging adequate temperature suitable for microbial environment (Bosque, S. 2019). Since both manual training of compost pile and parameter readings in the field consumes an intensive amount of labor and time, accommodating an operation with monitoring principle that has forced aeration mechanism resolves this matter (Pettinger, 2019) Forced aeration by blowers enables a controlling factor of temperature rise and fall (Yuan et. al., 2018) to which the temperature is suitable for prolonged presence of microbes (Michel et. al., 2012) in which would increase respiration of microbes that speeds up the rate at which the composting material breaks down (Mejias et. al., 2017.
Using t-test analysis for two Independent Samples/Groups on the duration profiled by degradation rate of both treatments through temperature and mositure content monitoring throughout the composting operation of developed automated forced aeration system using sensor controls by which is compared to conventional composting of manual turning was examined within a chamber. It has been found out that there is a significant difference between their durations. Because of that, the percent difference of the monitoring system with forced aeration principle to conventional composting principle was determined and was found out to generate greater in degradation rate which resulted a lesser duration on the whole composting duration of yielding carabao compost as production using this sdeveloped system.
Convenience dealt by the features of monitoring principle through Internet ogf Things (IoT) like the profile of the system can be viewed in the application called Blynk by which through the app, the user canm view the actual readings which is also automated to form a chart throughout the whole duration of the operation that could go way back as quarterly periods and the user can also control the mechanism of electric blowers in overriding manner of ON/OFF switches.
