Abstract

A study has been conducted on the effect of liquid waste on river water quality in Pekalongan city. Banger River, Meduri River, Loji River and Asem Binatur River in Pekalongan city are the objects studied. Water sampling was carried out at one polluted point. Based on water quality testing, it is known that among the four rivers tested, the rivers with the most polluted conditions are the Asem Binatur River, Loji River, Meduri River, and Banger River. This is because the samples were taken during the rainy season, so there is a possibility of soil erosion originating from areas along the river flow. The position of the Meduri River which is close to the sea is also a cause of the increase in the pollutant load in the test results, because the river is mixed with seawater when tidal flooding occurs. In addition, the Meduri River Basin (DAS) is a factory and industrial area, so that wastewater from these activities can also increase the pollutant load on the river. However, the majority of test results from the four rivers still exceed the required quality standards. This is due to the dense population, the large number of batik industries, and agricultural activities that produce waste and have an impact on the pollution of the surrounding rivers.

Abstract

This study presents the design and implementation of a smart feeder system integrated with real-time water quality monitoring powered by a solar photovoltaic system and based on the Internet of Things (IoT). The system automatically dispenses fish feed and monitors key water quality parameters such as pH, temperature, and Total Dissolved Solids (TDS). The ESP32 microcontroller was used as the main controller, integrated with multiple sensors and an MQTT-based monitoring application. The entire system is powered by a 30 Wp solar panel and a 12 V battery, enabling autonomous operation in remote areas without grid access. Experimental results show that motor rotation speed significantly affects feed distribution. The optimal feeding performance was achieved at medium motor speed with a feed distance of 8 m, ensuring uniform feed dispersion and low energy consumption (±14.4 W). Water quality parameters remained within the ideal range for freshwater aquaculture: pH 6.6–6.9, temperature 27.5–28.8 °C, and TDS 380–450 ppm. The photovoltaic system generated around 90–110 Wh/day, meeting the system’s daily energy demand (±45 Wh/day). This integrated IoT–solar solution demonstrates high efficiency and sustainability, suitable for rural aquaculture applications.
