The pulp and paper industry in Indonesia is one of the industries that provides a significant contribution to the economy of Indonesia. But on the other hand, the pulp and paper industry is also one of the industries that produces quite harmful waste water which is quite dangerous and has the potential to have a negative impact on the environment. The waste produced by the pulp and paper industry is eventually disposed back into the environment which usually rivers. This waste can cause serious problems and changes to the aquatic ecosystem. Therefore, it is necessary to monitor that waste so that the level of environmental pollution due to the disposal of the waste water to the environement can also be monitored. So far, many pulp and paper industries, especially in Indonesia, still use conventional methods to measure several parameters that must be measured in their wastewater treatment plants. This manual method is done by taking samples at the factory and testing these samples in the laboratory. This conventional method is certainly very prone to human error. In addition, this conventional method cannot detect any irregularities or measurement results that exceed the quality standard limit on wastewater parameters that occur momentarily. Also, in 2018, the Indonesian Ministry of Environment and Forestry issued a regulation requiring several types of industries in Indonesia to use an online monitoring system at all times during their wastewater treatment plants (WWTP). Therefore, it is necessary to design a system that is able to perform online monitoring functions at any time. In this online monitoring system for pulp and paper industry wastewater, the pH parameter value is one of the parameter values that must be measured. To measure pH parameters in this online monitoring system a suitable electrode or probe sensor is used for measuring the pH parameter. The results of measurements using these automatic sensors can later be viewed and displayed via an online monitoring platform so that the results can be observed by users, pulp and paper mill operators.4 The final result of the design and implementation of this system is a measurement module that can perform real-time pH measurements. This pH parameter measurement module system uses the concept of the Internet of Things system or commonly known as IoT. The measurement module measures the pH of wastewater every 1 hour. This online monitoring system is also able to provide alerts for measured pH parameters that exceed the quality standard to users via email. In addition, the measurement module also features a WiFi connection setting which makes it easy for users to select and set the desired WiFi connection. The measurement module also has an offline storage feature to store the pH measurement data when there is a problem on the internet network. The panel box. a part of the pH measurement module, also has water resistance IP standards that make this device have the ability to be placed in an outdoors open area and Save to rainy weather condition. Device has been tested to fulfill those functions.
