News, Student, , , ,

Dr. Mohd Noor Hisham Mohd Nadzir from the Department of Biology, Faculty of Science, Universiti Putra Malaysia gave a guest lecture on animal physiology (13/10). With the theme “Endocrinology and Reproductive Physiology of Beef Cattle”, the lecture was attended by students of the Animal Physiology course, Biology Department, FMIPA UNEJ online. At the beginning, Dr. Noor Hisham introduced what is meant by endocrinology. “Endocrinology is the study of hormones, and hormones are very important for daily survival as chemical messengers that move from one cell to another,” he explained. This guest lecture event was moderated by Purwatiningsih, S.Si., M.Sc., Ph.D.

It is said that scientifically, hormones communicate this effect through their unique chemical structure, which is recognized by specific receptors on their target cells. “Hormones will tell us or animals how to control various physiological activities, such as growth, development, puberty, level of alertness, regulation of sugar and appetite, bone growth, and stress,” he said. In short, hormones influence aspects of our daily lives to ensure the body maintains the balance necessary for health and survival. Continue reading →

Innovative, FMIPA UNEJ PKM-RE Team Overcomes Shrimp Pond Waste Using Shrimp Shell Biofocculant

News, Student, , , , ,

The PKM-Riset Eksakta Team, Faculty of Mathematics and Natural Sciences, University of Jember, headed by Rikma Dwi Mukharomah from the Chemistry Department, converted shrimp shells into chitosan, which was applied as a bioflocculant for treating waste water in shrimp ponds. This research team consists of Masrurotul Alfiah, Imelda Dwi Puspita, and Ka’aziyah Aulia Nada from the Chemistry Department and Indah Febrian from the Biology Department. Dr. Bambang Piluharto, S.Si., M.Si., from Department of Chemistry, FMIPA, was appointed as supervisor of the PKM-Exact Research Team, which won funding for the 8 Bidang Program Kreativitas Mahasiswa (PKM) in 2023.

“This research is expected to be an alternative to processing waste water from shrimp ponds,” said Rikma Dwi Mukharomah. The research was carried out for 4 months, starting June 16, 2023, at the Physical Chemistry and Organic Chemistry Laboratory, Department of Chemistry, FMIPA, University of Jember. Furthermore, Rikma explained that chitosan-based bioflocculant is synthesized from shrimp shells through several stages, including deproteination, demineralization, and deacetylation. “The result obtained after the deproteination and demineralization processes is chitin, while from the chitin deacetylation process, chitosan is obtained,” she explained.
