Utilization of Information and Communication Technology with the Internet of Things on Regosol Soil Characteristics

Information and communication technology with the internet of tings can be used to monitor soil moisture and soil fertility, water use will be more efficient, especially on Regosol soils which have low levels of soil fertility and water availability. This study aims to determine the role of the Internet of Things on soil moisture, pH and NPK of Regosol soil, to determine capillary irrigation and liquid organic fertilizer on soil characteristics. The method used in this study was a completely randomized design (CRD) with two factors. namely the type of fertilizer, consisting of 4 levels, P0: No liquid organic fertilizer, P1: 5 liters/ha of household waste liquid organic fertilizer, P2: 5 liters/ha Liquid organic fertilizer of biduri leaves, P3: 300 kg/ha NPK fertilizer. The second factor is the number of wick of capillary irrigation, consisting of 3 levels: I0 : No capillary irrigation, I1 : 1 wick of capillary irrigation, I2 : 2 wicks of capillary irrigation. The results showed that the soil moisture was 16.59-23.48%, the more capillary wick, the higher the soil moisture. Mustard plants began to wilt and lack of water in soil moisture at the permanent wilting point of 6.47%. Liquid organic fertilizer and capillary irrigation had no significant effect on soil moisture. Capillary irrigation has a significant effect on water volume, liquid organic fertilizer has a significant effect on soil pH, soil organic C and soil NPK levels
