Abstract

Manual tasks that still rely heavily on human skill and discipline cannot yet match the superior results achievable through automation. The designed waste bin model ensures no physical contact between the end-user and the bin during disposal. This is achieved by installing a sensor to detect obstacles approaching the bin. When an obstacle, such as the end-user, is within a range of 80 to 40 centimeters from the sensor's line of sight, the bin lid will automatically open. Additionally, a sensor inside the bin detects the waste height from the lid. When the waste reaches a predefined height of 40 to 20 centimeters, a buzzer will sound, and a notification will be displayed indicating that the bin is full. The model was designed using the Wokwi simulator and implemented with an ESP-32 microcontroller. The model also employs an embedded-systems approach. The results demonstrate that the device successfully detects obstacles in front of the bin, ensuring non-contact between the end-user and the bin. The predefined waste height is also accurately detected by the sensor, triggering a notification on the Visual-Display Unit (VDU) and activating the buzzer.

Abstract

Soil fertility is influenced by two dominant parameters, namely soil temperature and humidity. If one exceeds the reference value, it will certainly affect the level and level of soil fertility. Although nutrient management is also important, temperature and humidity parameters are the two main factors that must be considered so that ideal fertility levels can be maintained. It is necessary to have an instrument to control and to stabilize so that the soil temperature and humidity values can always be maintained; citing the need to avoid biased decisions if they are not based on empirical values. In this research, a series of tests have been carried out using an automatic controller, namely an instrument built and designed to have the capability to control soil temperature and humidity. The use of a specific sensor can detect changes in sensitivity in the soil, for temperature and humidity parameters. The test results show that in a series of trials using ten test scenarios; it was found that every environmental condition that is changed by direct intervention on the sensor shows that the automatic controller can quickly and in real-time provide feedback in the form of visuals and sounds as a warning that there has been a significant environmental change, so that action must be taken to return the soil condition to its normal reference-value.
