The sample collection process was obtained once a week for 12 weeks as this is to analyze the physical, chemical and microbiological characteristics of the rinds. The results showed that within the first 4 weeks, the temperature of the compost has decreased while the moisture content has increased. More so at 5 weeks it was shown that the nitrogen content decreases significantly as there was no degradation activity although there is still a large amount of Iron (Fe) compound left enough to be used as an energy source in the aerobic degradation process. Where this can be explained by the process of cell multiplication and bacterial decomposition that requires nitrogen, therefor the result in the decreased temperature caused by the high levels of moisture as well as the total nitrogen and C: N ratio does not meet the standard of organic fertilizer as this can be concluded that nitrogen is a limiting factor in the process of decomposing oxygenated durian rinds of bacteria during the rainy season. |
