Campus ITS, ITS News – Water is an essential element in human life, but what happens if the water is contaminated with hazardous waste? To overcome this, three students of the Institut Teknologi Sepuluh Nopember (ITS) designed a wastewater treatment system for dairy farms to not pollute the surrounding water.
Nabiilah Aziizh Tjandra, Team Leader, revealed that several dairy farmers have not been able to manage waste properly. He gave an example in Cepogo District, Boyolali Regency, an area with abundant livestock commodities. However, 56.67 percent of dairy farmers still dispose of waste in river bodies without management. “This happens because most of them are conventional farms, so they don’t have a waste management system,” he said.
Furthermore, Nabiilah explained, from the research that has been carried out, it is known that the quality of river water has a number that exceeds the permitted wastewater quality standard, namely Chemical Oxygen Demand (COD) of 20 – 80 milligrams per liter and Total Suspended Solid (TSS) which reaches 64 – 94 milligrams per liter. “Therefore, we need an appropriate wastewater treatment system so that it does not pollute the environment,” said the student from Surabaya.
Based on this, Nabiilah and her team designed a wastewater treatment plant using a bioreactor membrane integrated with the Internet of Things (IoT) to make it easier for farmers. “The bioreactor membrane was chosen because it has been proven to be effective in improving the quality standard of the processed waste output,” explained this first-year student.
In the installation system designed by his team, Nabiilah explained that wastewater from livestock would enter the reservoir before being passed through the bioreactor membrane for filtration. The system is also equipped with sensors to ensure the quality of the waste output by quality standards, which is less than 50 milligrams per liter. “When the quality is not met, the wastewater will be filtered back into the bioreactor membrane,” he explained.
Not only that continued, Nabiilah, the wastewater treatment system designed by his team, is equipped with sensors that will detect cake fouling due to trapped impurities. This cake fouling causes the filtration process to be inefficient, so the membrane must be cleaned from the cake. “With this sensor, farmers will know when the membrane needs to be cleaned,” explained Nabiilah.
Together with Nabiilah, this team consists of two other ITS Instrumentation Engineering Department students, namely Akbar Krisna Wandana and Ahmad Prayoga. They believe that their wastewater treatment system is 99.98 percent effective at filtering hazardous chemical substances. “In the future, we hope that our innovation can be realized soon so that it can provide benefits to the community,” said Nabiilah optimistically.
Through an innovation entitled Application of a Bioreactor Membrane with an IoT-based Waste Output Quality Monitoring System on a Dairy Cattle Farm in Cepogo District, Boyolali Regency as an Effort to Reduce River Pollution, Nabilah and her team won 1st Place in the Pertamina Smart Innovation Boyolali 2022 event held by Pertamina Patra Niaga Boyolali, not too long ago.
