Team Carbon Sunny Go Students of IPB University Bringing Smart Household Biodigester Based on the Internet of Things Won 1st Place in the 2022 Technocorner Competition

The Carbon Sunny Go Team from IPB University won 1st place in the 2022 Technocorner Competition held by Gadjah Mada University (UGM). This team consists of I Dewa Gede Wicaksana Prabaswara, a student of the School of Veterinary Medicine and Biomedical (SKHB) and Putu Oki Wiradita Aryawan, a student of Mechanical and Biosystem Engineering (TMB). The IPB University student was guided by drh Mokhamad Fakhrul Ulum, PhD, a lecturer at IPB University from the SKHB Reproductive and Pathology Clinic. This team carries the sub-theme of renewable energy with the title “Smart Household Biodigester: Smart Biogas Production System from Prayer Waste in Bali and Integrated Carbon Credit Trading Based on the Internet of Things.”
The Internet of Things (IoT) Development Competition itself aims to produce applicable and useful innovations to solve problems and provide solutions to problems. In this competition, participants are grouped into groups of a maximum of three people, where one person is the team leader.
"I am very happy to be able to bring the name of SKHB IPB University to the national event. During the competition process, I was accompanied by a very cooperative partner. We are guided by Doctor Ulum, a lecturer who is not only a mentor, but also a friend who is very understanding and makes every discussion comfortable,” said Dewa Wicak.
The IPB University student explained that his innovation started with the problem of the increasing trend of greenhouse gas emissions that damage the ozone layer and increase global warming. For this reason, carbon offsets as an effort to reduce greenhouse gas emissions must be intensified. One of them is by developing new and renewable energy which has the potential to be carried out in Indonesia.

Dewa said that the province of Bali has many temples, holy houses of the Hindu religion, which produce a lot of organic waste. Organic waste from the results of prayer activities is a problem in itself. Dewa Wicak and Putu Oki saw this problem and tried to provide a solution using IoT-based devices.

The IPB University student innovation consists of two parts, namely the gas monitoring system in the biodigester and the website which is prepared to be a carbon credit investment and trading platform. Dewa explained that the monitoring probes were placed in the biogas duct to monitor several types of gas produced. The gas in question is methane gas with an MQ4 sensor, hydrogen gas with an MQ8 sensor, carbon dioxide gas with an MQ135 sensor, and other bio parameters that affect the biogas production process. These bio parameters such as temperature, humidity, and pressure are monitored with the BME280 sensor.

Furthermore, said Dewa, data from these sensors is processed by Arduino nano and displayed locally on a 16 x 2 pixel LCD. The units displayed are ppm or parts per million for gas, Celsius for temperature, percent for humidity, and Pascal for pressure. The data is uploaded to the cloud server base and can be accessed by partners and customers on the website. (*/Ra) (*) (IAAS/AZA)
