Abstract

Rainfall refers to the amount of precipitation that falls in a specific area over a certain period, typically measured in millimeters (mm). High rainfall can increase the risk of flooding. This study aims to develop an IoT-based system to detect water levels, measure rainfall, and automatically control the opening and closing of floodgates. The collected data is permanently stored in a database and can be monitored remotely. The researchers utilized an Arduino Mega 2560 microcontroller and an ESP32 to process data, an ultrasonic sensor to measure water level (in cm), and a rainfall sensor (in mm). The data is transmitted to a Firebase database and connected to a Telegram bot, allowing administrators to monitor it in real time. The system classifies water levels into four categories: safe (0–30 cm), alert (31–40 cm), warning (41–50 cm), and danger (51–60 cm). Rainfall intensity is also categorized into four levels: light (0.5–20 mm/h), moderate (20–50 mm/h), heavy (50–100 mm/h), and extreme (more than 100 mm/h). The system automatically adjusts the floodgates based on water conditions but also allows for manual control. The sensors demonstrated an average accuracy of 97%, with an average notification delay of 675 ms during extreme rainfall conditions.

Abstract

Liquid organic fertilizer is a solution derived from the decomposition of organic materials such as vegetable, fruit, or household waste. The research aims to investigate the effect of organic waste mixture on liquid fertilizer that meets Indonesian National Standard (SNI). The method used is a direct experiment with the residents of Mujur village, where vegetable and fruit waste are collected and crushed. They are then fermented for 2 weeks with the addition of EM4 in a ratio of 1:1:100. Testing was conducted at the Mujur village farm secretariat. The results show that plants given Liquid Organic Fertilizer experienced faster stem growth. On the first day, chili plants grew 4.5 cm, and on the third day, 5.0 cm, while the comparison with ordinary water showed 4.5 cm on the first day and 8.0 cm on the second day. Based on the experimental results, it can be concluded that the treatment on the first and second day significantly proves that the liquid fertilizer produced is very good for plants.
