Abstract

The increasing volume of waste in urban areas necessitates a more efficient waste management system. Conventional manual collection methods are often ineffective and costly, facing issues such as schedule delays and dependency on labor. This study proposes an automated waste collection system using the OMRON CP1E-E40DR-A PLC, integrating waste detection sensors and robotic mechanisms. The effectiveness of sensor distance was tested 10 times to determine the optimal range that does not cause delays in the conveyor. Of the tests, 5 showed no delays, with an average efficient sensor distance of 50%. The total time efficiency for collecting 10 grams of waste was measured over 5 trials, with 3 tests demonstrating efficient distribution times. The average efficient time for the distribution process reached approximately 54.55%. The findings of this research highlight the potential of automated systems in enhancing waste management efficiency in urban areas.

Abstract

Agriculture is one of the most important sectors for society. Along with the times, many agricultural lands have been turned into residential areas, especially in office areas. Urban farming is a solution to overcome the limited land for farmingTherefore, there is a need for an innovation in the Hydroponic method, namely by making an automatic nutrient regulator in hydroponic plants. This research aims to make the provision of nutrients in hydroponic plants effective and efficient, as well as ease of monitoring by controlling through a smartphone. Controlling the actuator in the form of a pump can be done manually with keystroke instructions and can be done automatically with instructions based on the comparison of sensor readings and setpoints, namely if 1400 the regular water pump is on the nutrient pump is off, while if >=1050 and <=1400 both the nutrient pump and the regular water pump are off. Monitoring of nutrient levels (ppm) and water levels will continue to be displayed on the LCD and Blynk application both in manual mode and during automatic mode. The final result of testing this tool is found that the use of sensors in reading the value of nutrients (ppm) and adjusting the water level is more effective than manual nutrition. Because the sensor will intensely control the nutrient content needed by plants and the appropriate water level for Hydroponic plants. Monitoring of nutrient levels (ppm) and water levels can be seen through the LCD and in the Blynk application. The process of providing nutrients is done by controlling the pump to flow based on the instruction of the button press or based on the sensor reading with the setpoint.

Abstract

Powder coating is a painting process used to coat metal surfaces, providing a more durable and aesthetically pleasing finish compared to conventional painting. This method falls under the category of dry finishing, where the coating material is in the form of a fine powder consisting of a mixture of resin, color pigments, and other additives. The powder is electrostatically charged to adhere strongly to the cleaned metal surface. The coating process is carried out by spraying the powder using an electric spray gun, followed by a heating or oven curing process to melt and bond the powder permanently onto the metal surface. In an automated powder coating system, the movement of the electric spray gun and the metal object being coated is crucial to ensure uniform thickness and coating quality. For this purpose, two types of motors are used: a continuous rotation servo motor to rotate the object holder, and a DC motor to move the electric spray gun linearly. Both motors are controlled by an Arduino Uno microcontroller, which acts as the main control center, and an Omron CP1E PLC, which manages the overall industrial process control logic. The speed and movement time of the DC motor significantly affect the spray coverage distance. Based on testing, to reach a distance of 25 cm, the DC motor requires 3325 ms at a speed of 0.075 m/s. For a distance of 20 cm, the required time is 2670 ms, while for 15 cm, the motor runs for 2005 ms. These time calculations are essential to ensure that the metal surface area receives sufficient and even powder spray. With this system, the coating process can be performed automatically, efficiently, and consistently according to the programmed parameters.

Abstract

The development of innovation in the home coffee industry has the potential to boost the economy of the community. One commonly encountered problem is with the pressing tool that uses inferior plastic, resulting in inadequate heat production. Therefore, there is a need for development aimed at improving efficiency and increasing coffee packaging production. With the advancement of technology, the use of a sealer proves to be the most effective solution compared to plastic pressing. Several parameters need to be considered, including the heat generated and the sealer's movement during pressing. Hence, this tool utilizes pneumatic technology for the sealer's movement, as it is more effective than using a motor and is directly controlled using PLC

Abstract

The use of greenhouses can be an alternative in cultivating potato seeds with room conditions that can be manipulated according to plant needs. The greenhouse system can provide a solution for farmers because it can work automatically and can be monitored via HMI. This system can also perform the function of controlling room temperature and humidity, soil humidity, and soil pH according to the conditions around the greenhouse. The monitoring and data collection process includes data on room temperature and humidity sensor readings by maintaining the temperature below 24 ℃ with ambient humidity above 60%. Based on the results of monitoring soil pH and soil moisture, data was obtained that the system would maintain soil conditions with a pH value of 7.00 and humidity of 60%. The use of RTC in the pesticide spraying process is carried out in real time in the morning at 08.00 and afternoon at 17.00. The use of HMI as an interface for delivering sensor value data is very helpful for users or authors in the monitoring process and data collection.
