Easy and Practical: University of Jember Students Create Test Strips to Test Formalin Compounds

News, Student, , ,

Our PKM-RE team from the Chemistry Study Program, Faculty of Mathematics and Natural Sciences, Jember University, has successfully received funding from the Ministry of Education and Culture, Research, and Technology. Our PKM-RE team, consisting of Lina Sun Haji as team leader and members Choirun Nisa Anida, Caleysda Aprilianti, Himayah Izmi Fauziyyah, and Diah Ayu Pitaloka, has carried a theme entitled Test strip Berbasis Metil Merah Untuk Tes Cepat, Praktis, dan Ekonomis Senyawa Formalin dalam Sampel Ikan atau dapat disebut dengan Trifommer (Test strip Formalin Berbasis Metil Merah). Our teamwork program is accompanied by Dr. . Zulfikar, Ph.D., who helps, supervises, and directs the smooth performance of teamwork.

Formalin can also be known as formaldehyde, which is a chemical compound that is often used as a preservative for corpses in the embalming process. Formalin can be used as a preservative for corpses because it helps prevent body decomposition due to the nature of formalin, which can stop the growth of bacteria and fungi. However, formalin is often misused when preserving food so that it does not rot quickly. One of the foods that is often preserved is fish. Formalin is a food that is strictly prohibited from being added to food because it can interfere with the performance of the body’s organs. Continue reading →

Dean of FMIPA UNEJ: We Will Realize the Big Goal of FMIPA UNEJ Graduates Achieving 3.5 Rank 4

News, Student, , , ,

FMIPA UNEJ held the 101st Undergraduate (S1) and 74th Postgraduate (S2) Judicial Conference at the Faculty of Mathematics and Natural Sciences, University of Jember, Period 1 of the 2024/2025 Academic Year (19/7). Prospective graduates attended an open meeting of the FMIPA senate in the public lecture room of the FMIPA Biology Department. Led and opened directly by the Dean of FMIPA Prof. Drs. Dafik, M.Sc., Ph.D. the procession took place solemnly. In his graduation speech, the Dean congratulated the graduates. “On behalf of the institution, I would like to congratulate you on your graduation and achievements for at least 4 years in completing your studies at FMIPA UNEJ,” began the Dean of FMIPA. It was also said that the institution is proud because every year the number of graduates who arrive on time with an impressive achievement index continues to increase.

“At the start of this odd lecture, FMIPA will continue to improve to develop big desires and aspirations. I have a big goal of 3.5 to the power of 4 in mathematical terms,” he continued. Continuing, the first 3.5 is as much as possible for 3.5-year FMIPA students to take the thesis exam; the second is as much as possible to get a GPA of 3.5 to compete with competitors in the world of work. “The next 3.5 is the 3.5 month waiting period for FMIPA graduates to get a job, and the last 3.5 million is the first salary that FMIPA graduates get,” hoped the Dean, who was accompanied by the Vice Deans and the UNEJ FMIPA Senate at the senate session.

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 →

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.

Biochar is a process of transforming biomass into active carbon with a porous structure obtained from a pyrolysis process or combustion without oxygen. Making modified biochar consists of several stages. Continue reading →

CIGAMONS, PKM-RE University of Jember Team Creates Lead Adsorbent for Cigarette Industry Liquid Waste from Used Butts

News, Student, , ,

The tobacco products industry (IHT) is one of the sectors that contributes greatly to the national economy in Indonesia. One of the IHT products is cigarettes. One cigarette butt contains various dangerous substances such as arsenic, pyridine, and heavy metals, which, if thrown away, can pollute water. Liquid waste produced by IHT also contains nicotine, nitrosamines, and heavy metals such as Cu (copper) and Pb (lead), which can pollute waters and contaminate drinking water sources. According to the WHO, the habit of throwing cigarette butts carelessly is carried out by millions of people; at least two-thirds of cigarette butts are found scattered on sidewalks, cafes, and parks and end up in rivers and even the ocean.

CIGAMONS is here as the Jember University PKM-RE Team to answer this problem. The team consists of 5 people, namely Moh. Zeinur Ridho, Retno Pertiwi, Eldo Delta Bagaskara, Raya Rambu Rambani from S1 Chemistry, and Chika Synthia Pitaloka from S1 Environmental Engineering who were supervised by Dr. Muhammad Reza, S.Si., M.Sc., M.Si. This team successfully passed funding for the Student Creativity Program in the field of Exact Research (PKM-RE), with the title “Pemanfaatan Puntung Rokok Bekas Termodifikasi Surfaktan Alami Sebagai Adsorben Timbal Pada Limbah Cair Industri Rokok Dalam Upaya Penerapan Ekonomi Sirkular“.

The theme of the workshop was “Development of EPICS-Based Instrumentation and Control Systems in Accelerator Research Facilities.” The material was delivered by Dr. Keerati Manasatitpong and Mr. Natthawut Suradet from the Thai Research Institute (SLRI), or Synchrotron Light Research Institute. BRIN is collaborating with the Asia Pacific Center for Theoretical Physics (APCTP) to organize the workshop.

To take part in the workshop, participants from universities in the country are given the opportunity to take part in the selection stage after registering. After being declared successful, Ahmad Haris Rasidi, a student from the Physics Department at FMIPA UNEJ, received an invitation to the EPICS workshop along with accommodation which was fully borne by BRIN. “I will take advantage of this golden opportunity to learn more about the EPICS program in industrial control systems,” he said. Haris hopes that there will be a lot of new knowledge that can be brought back to Jember after attending the workshop, of course valuable experience during the five days of training.
