Solution! “TOBICHAN” PKM-RE Team from FMIPA UNEJ Creates Environmentally Friendly Innovation as a Solution for Handling Tobacco Stem Waste in the Jember

News, Student, , , ,

Tobacco is one of the leading commodities in Jember Regency, East Java. So far, tobacco stem waste has not been widely used by the community. Tobacco sticks are usually just thrown away or buried in the ground. Tobichan created a new innovation where tobacco stem waste is converted into modified biochar through ion exchange of Fe compounds to obtain biochar with high nitrate absorption capacity.

Modifikasi Biochar dari Limbah Batang Tembakau Untuk Meningkatkan Kapasitas Adsorpsi Nitrat Dalam Air was developed by the PKM-RE team, Faculty of Mathematics and Natural Sciences, University of Jember, often referred to as TOBICHAN’s Team. TOBICHAN’s team consists of 5 students from the UNEJ Faculty of Mathematics and Natural Sciences, namely Inggrit Ayuningtyas, Sultan Adil Lanang Sejati, Desi Fitrianingsih Nst., Ifa Inayatul Fauziah, and Fatma Astri Aini, accompanied by a lecturer from the Chemistry Department, FMIPA UNEJ, namely Dr. Bambang Piluharto, S.Si., M.Si.

INNOVATIVE!!! PKM-RE Team from FMIPA UNEJ treats Microalgae Waste Using Magnetic Chitosan from Shrimp Shells

News, Student, , , ,

The Student Creativity Program Team for Exact Research (PKM-RE) Faculty of Mathematics and Natural Sciences, Jember University presented an innovative solution to overcome the problem of microalgae waste. The team headed by Imelda Dwi Puspita from the Chemistry Department consisted of Muhammad Ragil Ainur Rahman, Ka’aziyah Aulia Nada, and Sya’rifa Salma Musliyati Putri from the Chemistry Department and Silfia Ayuni from the Biology Department. This team is guided by chemistry and environmental lecturer Dr. Bambang Piluharto, S.Si., M.Si. from the Chemistry Department, FMIPA UNEJ and passed the 2024 PKM 8 Sector funding stage. This research is entitled “Flokulasi Mikroalga Menggunakan Kitosan Magnetik serta Uji Potensinya sebagai Pupuk N dan P”.

Microalgae are photosynthetic aerobic organisms that grow widely in shrimp ponds. These organisms can become agents of water pollution if not managed properly. “Microalgae contain high nutrients but can cause eutrophication and disrupt the balance of the pond ecosystem,” said Imeda. Apart from microalgae, shrimp ponds also produce other waste in the form of shrimp shells. The abundance of shrimp ponds also increases the amount of shrimp shell waste produced, so creative innovation is needed to maintain ecosystem balance. Continue reading →
