LEARNING DESIGN OF EXPONENTIAL NUMBERS THROUGH THE DESIGN OF A HYPOTHETICAL LEARNING TRAJECTORY USING DISCOVERY LEARNING
Get PDFThis research aims to develop an effective learning design for understanding the concept of exponentiation by applying the Discovery Learning model using the Hypothetical Learning Trajectory (HLT) as the framework foundation. The research method used is a design research method consisting of three main stages: preliminary design, teaching experiment, and retrospective analysis. The initial stage involves literature analysis and the design of an HLT tailored to the concept of exponentiation. The instructional design is based on the prepared HLT and tested through two experimental stages: pilot experiment and teaching experiment. Retrospective analysis is conducted to compare the initial HLT with the Actual Learning Trajectory (ALT) achieved during the learning process. Data is collected through observation to monitor learning activities and environmental conditions, as well as through recordings of learning activities to gain an understanding of student participation in the design experiments. Additionally, Student Worksheets (SW) are used as aids for students to understand the concept of exponentiation, and evaluation questions are used to measure students' learning outcomes in the subject matter. Interviews are also conducted to gain a deeper understanding from the student's perspective. The results of this research make a significant contribution to the development of more effective mathematics learning methods, particularly in understanding the concept of exponentiation, and provide guidance for teachers to design learning that is more relevant to students' daily lives. The implications of the research results provide guidelines for teachers in designing learning that is more relevant to students' daily lives
IoT-based Water Quality Control in Tilapia Aquaculture Using Fuzzy Logic
Get PDFTilapia (Oreochromis niloticus) is a prominent species in freshwater aquaculture due to its high protein content and economic value. Maintaining optimal water quality is crucial for the health and growth of tilapia, particularly in terms of pH levels. Deviations in pH, whether too acidic or too alkaline, can lead to decreased appetite and increased mortality rates in tilapia. The objective of this study is to design an intelligent control system to monitor and regulate the pH and temperature of tilapia aquaculture ponds using the Sugeno Fuzzy method integrated with Internet of Things (IoT) technology. The system employs DS18B20 temperature sensors and E-201-C pH sensors to collect real-time data on pond conditions. The data are then processed by an ESP32 microcontroller, which employs Sugeno Fuzzy logic to determine the appropriate adjustments to be made. The system administers pH buffers to maintain the water within the optimal pH range. Furthermore, the collected data are transmitted to a web server, enabling real-time monitoring and analysis. The findings indicate that the proposed IoT-based system is effective in maintaining water quality, ensuring that the pH and temperature levels remain within the ideal range for tilapia. This study demonstrates the potential of integrating IoT and Sugeno Fuzzy logic to provide a robust solution for managing water quality in aquaculture settings, enhancing the sustainability and productivity of tilapia farming
