<![CDATA[The level of water pollution sourced from daily household waste needs to be watched out, especially since the level of awareness of the Indonesian people is still relatively low in water treatment. Waste water treatment plants are always synonymous with high installation costs and the complexity of maintenance and management of the installation equipment. Based on the above background, the authors make a household wastewater treatment installation device in the Lirboyo Al-Mahrusiyah Islamic Boarding School Dormitory, Kediri City, into ready-to-use water for urban agriculture using the hydroponic system method. This device is based on a microcontroller that is connected to the Blynk Web Server which can be operated using a Smartphone. This system is also able to provide results of monitoring the quality of water quality standards resulting from waste treatment in the Lirboyo Al-Mahrusiyah Islamic Boarding School Dormitory. This application can also be applied as a remotecontrol tool by utilizing the internet network to determine the quality of household wastewater quality standards with a water acidity level (pH) of 7.12 and a TDS (Total Dissolve Solid) value of 521 mg/L and turbidity of 5 NTU (Nephelometric Turbidity Units) in real time.]]>
