The cross-departmental research team of the Faculty of Mathematics and Natural Sciences, University of Indonesia (FMIPA UI) consisting of Adi Wibowo, Ph.D. (Geography), Dr. Eko Kusratmoko (Geography), Dr. Supriatna, M.T. (Geography), Iqbal Putut Ash Shidiq, PhD (Geography), Dr. Supriyanto (Geoscience), Sukarno Bin Gendon, M. Si. (Geoscience), and Nugroho (Geoscience), developed an automatic local climate monitoring system to monitor air temperature, humidity, and rainfall in real time. online.
This system uses climate parameter sensors for air temperature, air humidity and rainfall, along with location coordinates. Global Positioning System, which is operated in real time from the monitoring location via communication data transmission. cellular or communication Internet of Things (IoT). For local climate data, theoretically it can monitor an area of about 100 square meters.
Team leader, Adi Wibowo, Ph.D. said the advantage of this innovation is the data on air temperature, air humidity, and rainfall that has been sent to the system. cloud server can be monitored automatically and can be accessed by anyone, without having to record or download manually. The web display has also been improved to get updates per hour, day, week, month, and year.
This tool is operated with electricity generated from a 12 watt peak (WP) solar panel. In the FMIPA UI environment itself, this tool is installed in the Geography Building and in the Geography Building parking area.
“The energy generated by a small solar panel measuring 12 watt peak (WP) as an energy source stored in the battery. The data is collected for 24 hours, however, it depends on the condition of the sun during the day that is able to fully charge the battery. If the battery runs out, then the next day when the sun rises, the device will automatically turn back on to collect data," said Adi to the FMIPA UI Public Relations team.
He continued, in general there are quite a lot of climate elements, but only 3 climate elements can be monitored on this tool, namely air temperature, air humidity and rainfall. For these conditions associated with the elements of the earth's surface cover, for example covered with trees and covered with asphalt/cement, then this innovation is able to monitor the conditions of these climate elements both during the day (there is sun) or at night (without sun). So that we can get the conditions of the climate elements during the day and at night.
"Every 10 minutes the data will be updated through this system. Another connection is as an indicator in the greenmetric calculation, so that this system can monitor where the hot and cool places are in the environment around the device where the device is installed," he said.
his innovation began to be developed by Adi and the FMIPA UI research team in 2022 through a funding scheme obtained from PUTI Q2 and PDUPT for devices registered for patents in 2022 and for patents in 2023 received PUTI Batch 3 grant funds. The design process began by determining the device as a sensor capable of recording climate elements of air temperature, air humidity, and rainfall. The team then analyzed and created a communication system to record these three elements from each sensor, then the team created a source of electrical energy through batteries/power banks, and also solar energy.
The sensors, communication systems, solar panels and batteries that had been prepared were placed in a box with support poles that had been specially made by the team so that they could be placed properly at the monitoring location. After that, the team created a database and communication system based on IoT and cloud server and design a web display so that it can be accessed by users to find out the latest local climate conditions.
"Of course the results are stored on the server and can be used as data for further analysis purposes," he said.
This innovation has been tested in Narimbang Village and Citengah Village, Sumedang Regency, as a community service activity in November 2022, and the results showed that the tool operated well.
Head of the Geography Department and member of the research team, Dr. Supriatna, M.T. said that this innovation was carried out to answer the needs of the wider community for information about the weather and climate in their environment. Thus, the community can plan or adjust their outdoor activities based on the results of weather and climate monitoring in the future.
"We designed this tool to help the community monitor the weather or climate in their environment, so that they can do outdoor activities according to the monitoring data," said Dr. Supriatna.
He is optimistic that this innovation can be further developed by adding sensor features for other climate parameters such as wind direction and speed sensors, sunlight, and ground surface temperature. So he hopes that his team will get more funding support so that they can continue research to develop this innovation.
