The rapid development of shrimp farming has created problems. One of the main problems in shrimp ponds is the quality of pond water which must be in accordance with the needs of shrimp life, the monitoring process is usually done manually. Internet of Things (IoT) based shrimp pond water quality monitoring is made to make monitoring easier. The device has 2 systems, namely 3 inputs in the form of a temperature sensor, a pH sensor and a salinity sensor, while the output part is an LCD (Liquid Crystal Display), Blynk, water pump, dc fan and dc motor controlled by Arduino Mega 2560. The process of sending data to Blynk uses NodeMcu. Test analysis is done by taking samples from different values. The formula y=a+bx is used in sample processing using linear regression. The average accuracy of each temperature sensor = 99.10%, pH sensor = 99.09% and salinity sensor = 90.98%. The error of each temperature sensor = 0.90%, pH sensor = 0.91% and salinity sensor = 9.12%.

One of the main goals of science education is to encourage the intellectual development of students. In this case, what is to be achieved is that most students can develop their potential at the level of formal reasoning. In general, in today's science learning, reasoning has not been managed optimally, planned, and systematically. The low ability of students to solve problems and the level of reasoning affects their low learning achievement. One of the reasons is that so far students are more required to develop low-level thinking patterns. Preparation of a quality generation should be done through empowering students through problem solving by improving reasoning in any approach, strategy, method or technical effort of learning. Scientific reasoning is one of the factors that affect student achievement in science. Scientific reasoning also contributes to academic achievement, cognitive abilities, decision making, and problem solving. Scientific reasoning can be used as a foundation in understanding and doing science as well as an integral part of problem solving.
