Abstract

This study examines the inefficiencies encountered by a training institution in Bandung Regency that utilizes a manual handwritten ledger for managing diverse data, including student information, teacher records, class details, student learning progress, and grades.  The current technique results in considerable delays in information retrieval, as perusing physical data is often time-intensive.  Moreover, producing reports for institutional control becomes burdensome, eliciting apprehensions of data accuracy, potential harm, or loss of vital information.  To address these challenges, we created a course information system utilizing the CodeIgniter framework.  The study utilized a descriptive methodology, and the system development applied Object-Oriented Analysis and Design (OOAD) concepts.  We employed Unified Modelling Language (UML) methodologies during the software design process.  The newly created course information system aims to streamline user data management and enhance the efficiency of recording operations for all participants, including administrators and educators.  The digitization of information management decreases retrieval times and enhances data accuracy and security, consequently promoting improved decision-making and reporting within the institution.

Abstract

A chili plant monitoring system has been created to increase crop yields, this system monitors soil pH and soil moisture in order to increase the growth of chili plants so that the yield obtained is maximum. This system uses Arduino UNO as its microcontroller with output in the form of automatic plant watering and automatic fertilizer. Important variables to support plant growth are soil moisture, soil pH, and the right watering time and duration. Measurement of soil pH and soil moisture is carried out using soil moisture sensor and soil pH sensor. While the output produced from the water pump and fertilizer and servo motor as the control. The measurement results of the two sensors will then be displayed on the LCD (Liquid Crystal Display). The test results of soil pH monitoring tools and soil moisture in chili plants show measurement results with good accuracy. The measurement results have been successfully displayed on the LCD, as well as the pump ejects automatically and the servo controls automatically.
