Abstract

This study aims to analyze the performance of an automated control system in a piggyback greenhouse that implements a Programmable Logic Controller (PLC) as the control center, using a wick irrigation system for the plants. A piggyback greenhouse is a multi-story greenhouse concept designed for space efficiency in urban agriculture. This system utilizes soil moisture, temperature, and light sensors to monitor environmental conditions, along with actuators such as water pumps and ventilation systems controlled by a PLC. The wick irrigation method was chosen for its efficiency and energy savings, as water is absorbed by the plants through capillary action. Tests were conducted in several environmental scenarios to assess the response and stability of the automated control system. The test results showed that the system was able to consistently maintain soil moisture within the optimal range of 60–80%, with an average response time of 3 seconds for pump activation. Furthermore, the use of a PLC allows for flexibility in control logic settings and operational efficiency. Overall, the PLC-based piggyback greenhouse system with wick irrigation has proven effective in improving agricultural environmental control and supporting small-scale precision agriculture concepts. This research can serve as a basis for further development in the application of automation technology in the modern urban agricultural sector.

Abstract

The problem of limited energy and high household electricity consumption in Indonesia encourages the importance of implementing energy-efficient lighting technology. The still high use of energy-wasting incandescent lamps indicates the low energy literacy of the community in choosing efficient types of lamps. This study aims to analyze and compare the energy efficiency of three generations of lamp technology, namely incandescent lamps, compact fluorescent lamps (CFLs), and LED lamps, with an experimental approach. Testing was carried out using a wattmeter, lux meter, and infrared thermometer in a closed room with controlled conditions. Each type of lamp was tested with a light output equivalent to ±800 lumens. The test results showed that LED lamps had the lowest power consumption of 10 watts with the highest efficiency of 80 lumens per watt and a surface temperature of 45°C. CFLs have a power consumption of 15 watts with an efficiency of 53.3 lumens per watt and a temperature of 70°C. Meanwhile, incandescent lamps consume 60 watts with an efficiency of only 13.3 lumens per watt and a surface temperature of 120°C. Simulation of household use shows that the use of LEDs can save electricity costs of up to 112,500 rupiah per month compared to incandescent lamps. The results of this study provide empirical evidence that LEDs are the most efficient lighting solution in terms of energy, cost, and safety of use for the household sector.
