Abstract

This research looks at how light intensity affects the power generated by a 640 WP solar panel. Given the reduction in fossil energy production and the global commitment to reduce greenhouse gas emissions, the use of renewable energy has increased. Indonesia has a great opportunity for solar power development as it has a solar energy potential of about 4.5 kilowatt hours per day. This study was conducted at KWT Kemuning Farm from March to July 2024. The measurement results show that there is a significant correlation between light intensity and power generated. The results show that the light intensity is directly proportional to the power generated. The highest light intensity of 156300 Lux at 13:00 WIB produced 127.08 Watts of power, while the lowest light intensity of 26300 Lux at 16:00 WIB only produced 10.01 Watts of power. Power fluctuations were seen throughout the day, with the highest average power peak occurring between 11:00 am and 2:00 pm. This study provides important information on the relationship between light intensity and power generated, which can be used to improve the efficiency of solar panel technology in the future.

Abstract

Shallots (Allium cepa var. ascalonicum) require effective irrigation to grow optimally. This research presents an IoT-based automatic watering system using Mamdani fuzzy logic method as watering control. The system uses two inputs, namely soil moisture and air temperature, and one output in the form of a watering pump. Soil moisture testing was conducted in three conditions: dry (0%-50%), moist (50%-70%), and wet (70%-100%). In addition, the tests also involved air temperature measurements categorized as cold (0°C-20°C), normal (20°C-32°C), and hot (32°C-50°C). The results show that the ideal humidity is between 55% and 58%. If the humidity exceeds 60%, the pump turns off to prevent the soil from getting too wet, and if it drops below 55%, the pump turns on as the soil starts to dry. Air temperature measurements showed consistent fluctuations throughout the day with small differences between the RTD PT-100 and Thermohygro Meter. The highest temperature occurred at 13:00 and the lowest at 18:00. This data is important for environmental management and system operations.

Abstract

This study aims to evaluate the use of the PWH137C motor in an automatic watering system for shallot plants built in KWT Kemuning, Prabumulih, which is operated via the Internet of Things (IoT). This system is designed to improve the efficiency and effectiveness of watering by using Internet of Things (IoT) technology for remote monitoring and control. To ensure proper water distribution to plants, the PWH137C motor was chosen because of its ability to pump water efficiently and stably. This study focuses on analyzing motor performance, implementing soil moisture meters, and creating system control software. The study shows that the Internet of Things (IoT)-based automatic watering system can improve watering efficiency and ensure optimal growth of shallot plants.

Abstract

Height measuring device is a tool used to measure a person's height. The commonly used height scale is the manual type which reads the measured height. Manual measurement in today's modern era is very ineffective when used on a large scale, especially in this era where there are so many digital tools. The specialty of this automatic height measuring device is that it can easily measure the height of many people. The operating system of this tool is to measure height automatically, so that measurement data can be stored automatically in the database. Compared to analog measuring devices that only measure one object and cannot store measurement data. In this study the authors made an automatic height measuring tool different from the usual. The author developed a previous automatic height measuring device using two ultrasonic sensors. The first ultrasonic sensor is used as a height meter and the second ultrasonic sensor is installed at the bottom to detect the legs to avoid cheating and also adds a measuring mat above the head so that the height measurement is really accurate.

Abstract

Onion plants require consistent watering to provide nutrients. Watering that is inconsistent and done manually is often inefficient, requires a lot of labor, and can inhibit growth and reduce crop yields. This automatic shallot plant watering system uses the sugeno fuzzy logic method because the sugeno fuzzy logic method is very accurate in making decisions. there are three main conditions that determine the watering of shallot plants based on measurements of soil moisture and temperature. In the first condition, soil moisture is recorded at 34% with a temperature of 29°C, so the water pump is activated for 30 seconds to maintain optimal soil moisture. In the second condition, soil moisture increased sharply to 341% with a temperature of 34°C, so the water pump was activated for 48 seconds to reduce excess moisture. In the third condition, the soil moisture reached 639% with a temperature of 33°C, and the water pump was activated for 20 seconds to overcome the excessively wet soil conditions. Through the use of Sugeno's Fuzzy Logic method, the system is able to respond to changing environmental conditions quickly and efficiently, ensuring that shallot plants receive the appropriate watering for optimal growth.
