| dc.description.abstract | This system is designed to monitor the stability of compost media maturity parameters. Users can use the composter machine more effectively and efficiently with the use of a sensor system for compost maturity parameters such as weight, pH, humidity and temperature combined with a 1 HP AC electric motor, gearbox and ATMega Pro 2560 microcontroller. The test was carried out using mangrove leaf litter, lamtoro leaves, water hyacinth and goat manure as raw materials for composting. In this test the temperature set on the composter machine is 45°C and the setting time is 3 days, so the temperature does not exceed 45°C and does not exceed 3 days due to the performance of the automatic stirring system. The test results show that this tool can maintain the stability of weight, pH, humidity and temperature parameters in compost media as evidenced by the fulfillment of the minimum value of compost quality standards according to SNI 19-7030-2004 and Decree of the Minister of Agriculture Number-261 KPTS SR.310 M 4 2019, with a maintenance temperature not exceeding 45°C and a stirring time of no more than 3 days after the first stirring takes place. Based on the experiments conducted, the composting process took 20 days with a heavy shrinkage of 13.74% and a decomposition rate of 0.85 kg/day. Thus, the design of the compost maturity monitoring system in the Internet of Things integrated automatic stirring composter developed in this study succeeded in providing practical methods in processing organic fertilizers. | en_US |
