Abstract

The development of the Indonesian agricultural sector until 2014 according to the Strategic Plan data of the Ministry of Agriculture for 2015–2019 is about 3.90% of the economic sector. One of the most important parameters for improvement efforts is soil. Soil quality on agricultural land is one important thing that needs special attention in its management. It is not easy to create ideal soil conditions for plants. For that, farmers need to know the variables that affect ideal conditions. The easiest way to find out the variable is to measure the pH and humidity of the soil conditions. Evaluation of soil fertility in chili plants is still done manually through visual observation. One of the factors that makes chili plants die before they bear fruit. In this research, a web monitoring system will be made on the planting medium of chilies based on soil acidity and soil moisture using sensors that can be monitored online. Data will be stored in the database and displayed on the web. The results obtained on the growing medium of chili plants produced soil suitable for chili plants, namely soil media sandy which has a moisture value of 7 to 8 and a pH value of 6.5-7.5. The average time needed to communicate between nodes to the website is 344 ms, which in the TIPHON standardization the average value of delay in sending data from the device to the website belongs to the 3rd index, which means that the process is of moderate quality.

Abstract

PH is the standard value of degree of acidity expressed on a scale 0-14. PH can be influenced by several factors such as temperature and CO2. Acidification occurs because CO2 enters the liquid in the form of dissolved gas then reacts with water to form a salt in the form of carbonic acid. The acidity can be determined by measuring the pH. PH measurement is an activity to determine the value of degree of acidity. PH measurement is needed to reduce the impact on the environment because pH is closely related to pollution. However, the existing measurement tools are still manual, while real time measurement is needed so the impacts on the environment can be prevented. In this study, a system that can measure pH which is influenced by CO2 concentrations in real time was created. This system consists of CO2 sensor, pH sensor, Arduino UNO R3 and Raspberry Pi. Apart from real time, the advantage is its ability to perform data acquisition using programs written in the Python 3.x programming language, so that data can be presented in tables and heatmaps. The results of sensor readings from the microcontroller to the raspberry pi can operate properly with delivery times via USB. Overall testing the system at reading the pH value is as expected, able to read the change in pH value significantly in pH of a neutral solution (7.3) and read the change of pH value that is relatively the same after the solution is injected with CO2.
