Abstract

Physics is a science with many similarities in each subject. This research on physics calculations aims to create a simple physics calculator based on Python programming. The purpose of this research is to create an electronic physics calculator (e-KalFisika). E-KalFisika is an application used for digital or electronic physics learning. This application provides learning materials, experimental simulations, practice problems and other features that support the understanding of physics concepts. The e-KalFisika application is only in development to solve the problem of calculating physics formulas. The result is e-KalFisika with better calculation results than manually.

Abstract

This study presents an innovation design for an Internet of Things (IoT)-based watering and liquid fertilizer control system for chili plants using a NodeMCU ESP32. The main problem addressed is the manual watering and fertilizing process, which makes it difficult for farmers to monitor soil moisture, temperature, air humidity, and light intensity in real time. The recommended method used in this draft is Research and Development (R&D) with a prototyping approach because the study focuses on designing, building, integrating, and testing an IoT device through iterative stages. The system is designed using a soil moisture sensor, DHT11, LDR sensor, two-channel relay, two 12 V DC pumps, 16x2 I2C LCD, and the Blynk Mobile application for remote monitoring and control. Sensor data are transmitted to Blynk as percentage values and plant condition statuses, while the water and fertilizer pumps can be controlled using virtual buttons. The control logic defines the optimal condition for chili plants based on soil moisture of 60-80%, temperature of 25-30°C, air humidity of 60-80%, and light intensity of 50-90%. Prototype documentation and functional testing data will be completed in the next stage.
