Collaborative Teaching: Philosophy of Science and Bioethics by Barlah Rumhayati, Ph.D. from Brawijaya University

News, Student, , , , ,

Barlah Rumhayati, S.Si., M.Si., Ph.D., Head of the PhD Chemistry Study Program, Department of Chemistry, Faculty of Mathematics and Natural Sciences, Brawijaya University, gave a lecture on Philosophy of Science and Bioethics for Master of Biology students, Department of Biology, FMIPA, University of Jember, on October 9 and 16, 2023. At the beginning of the lecture material, Dr. Barlah explained the meaning of the philosophy of science. “The philosophy of science is a branch of philosophy that studies and systematically questions the nature of scientific knowledge,” she explained. This scientific knowledge relates to philosophical and fundamental issues to achieve scientific knowledge.

Guided by Master of Biology FMIPA UNEJ Lecturer Purwatiningsih, S.Si, M.Si., Ph.D. collaborative teaching is held online. Dr. Barlah also gave the example that when preparing a thesis, master’s students must be systematic or sequential. “In preparing a thesis based on a problem, the solution or answer to the problem must be philosophical, systematic, and fundamental,” she continued. Also, when preparing the conceptual framework of a thesis, it must be philosophical and fundamental to the issues raised or discussed. Continue reading →

Animal Physiology Guest Lecture by Dr. Mohd Noor Hisham Mohd Nadzir from Universiti Putra Malaysia

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, , , , ,

“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.

Parasitic Plants: Sharing Session Lecture on Parasitology by Dr. Zaiton Sapak from Universiti Teknologi MARA Malaysia

News, Student, , , , , ,

Dr. Zaiton Sapak from Universiti Teknologi MARA Malaysia delivered material on parasitic plants in the Parasitology Lecture Sharing session (3/10). Parasitic plants, or parasitic plants, are organisms that settle on host plants through special organs. “This special organ develops and penetrates the host’s vascular tissue and meets the nutritional, water, and mineral needs of the host plant,” began Dr. Zaiton Sapak. It is said that nearly 4,500 species in 28 families, representing 1% of all angiosperm species, utilize the vascular systems of other plants to meet their nutritional needs.

Sharing session guided by Purwatiningsih, S.Si., M.Si., Ph.D. The lecturer at the Department of Biology also explained that parasitic plants are divided into several types, seen as being photosynthetically active (hemiparasites), lacking photosynthetic activity, completely bound to the host for carbon (holoparasites), optional or obligate parasites, and attached to the roots or stems of their hosts. “Parasitic plants” grow in agroecosystems with low biodiversity, and their presence causes huge yield losses on agricultural land,” said Dr. Zaiton Sapak.

Congratulations and Success! FMIPA University of Jember Has Three New Professors  

News, Tokoh, , , , ,

FMIPA Jember University increased the number of professors after the Kementerian Pendidikan, Kebudayaan, Riset, dan Teknologi appointed three lecturers as professors. First Prof. Dr. Anak Agung Istri Ratnadewi, S.Si., M.Si., is a professor in the field of biochemistry in the Chemistry Department, FMIPA. Prof. Dr. Kahar Muzakhar, S.Si., is a professor in the field of microbiology in the Biology Department, FMIPA. And the third is Prof. Dr. rer. nat. Kartika Senjarini, S.Si., M.Si., is a professor in the field of molecular biology, which is also in the Biology Department, FMIPA UNEJ.

“Congratulations and success to the three new professors; it is a matter of pride for us, the FMIPA academic community, for this appointment, so that now there are seven professors at FMIPA UNEJ,” said Drs. Achmad Sjaifullah, M.Sc., Ph.D. Dean of FMIPA, some time ago. The Dean also said that, apart from professors, he also encouraged and provided assistance to all FMIPA lecturers in managing promotions and functional positions. “We pay attention, so we create a special quarantine for lecturers who are committed to fulfilling PAK requirements,” he continued.

Collaboration in Teaching Biodiversity Courses: Masters in Biology, FMIPA UNEJ, and FMIPA UB

News, Student, , , ,

Master of Biology FMIPA Jember University and Master of Biology FMIPA Brawijaya University held a collaboration to teach biodiversity courses online (15/9). Prof. Dr. Amin Setyo Leksono from Brawijaya University, as the speaker, delivered material on animal population estimation methods. “We need an animal population approach first, both census and sampling,” he initially said. Continuing the census requires a lot of personnel to count all the flora in an area. Meanwhile, sampling can be done using direct or indirect analysis.

Prof. Amin continued direct sampling itself, divided into several methods. “There are quadratic methods, transect lines, exploration and exclusion methods, and finally we have to calculate the population size,” he continued. For indirect methods, there are several methods, including traps, concentration calculations, trace counts, and interview methods. The conclusion from the initial session was that the benefit of animal estimation is knowing population dynamics patterns, including influencing factors. “We come to know the potential of each type, its role and benefits, and finally, what policies to take for this population,” he concluded.
