MIPA CENTER, Located in the 7th Floor Auditorium, MIPA CENTER Building UB Faculty of Mathematics and Natural Sciences (FMIPA), Dean departed four PIMNAS teams to be ready to compete in Yogyakarta State University, (27/08). The preparation of the PIMNAS participants was carried out in earnest, from the presentation simulation to preparing the completeness of the PKM. Not only that, the support and motivation of the supervisors is continuously carried out so that the participants can fight optimally.

Dean of FMIPA, Drs. Adi Susilo, Ph.D officially dispatched the PIMNAS team and provided motivation to stay motivated and struggle to get maximum results when competing.

4 This team consists of (1) Muhammad Rizka Maulana, Gigih Satrio Wibowo, Mochammad Rizky Wijaya; (2) Wildatus Sa’diyah Sugianto, Diyah Nitami, Yuda Alldiansyah Ramadhon; (3) Aisha Bella Anindita, Diyah Nitami, Wildatus Sa’diyah Sugianto; (4) Muhammad Rizka Maulana, Satrio Wiradinata Riady Boer, Adin Okta Triwadafi, Fikriya Novita Sari, Firdausi.

The Dean of FMIPA said that he felt proud and happy for the achievements of FMIPA students who would take part in the 2018 PIMNAS in Yogyakarta on August 28 – Septermber 2018.

“You all have a fighting mentality, whoever the opponent is, has a winning mentality,” said Drs. Adi Susilo, M.Sc., Ph.D.

Meanwhile the PIMNAS FMIPA team itself is targeting the Gold Medal and Silver Medal to be presented to the Faculty of Mathematics and Natural Sciences in the event later.

The research topics contested by the PIMNAS FMIPA UB team included FASTER FROVER (FAST WRAPPER and POSITIONING MARKER FRUIT COVER) which discussed methods that could facilitate fruit farmers in packing guava fruit, predicting harvest time, and fruit distribution. Interestingly, this team uses a user friendly Android-based SMARTPHONE device. The benefits achieved in the harvesting process can reach 14 million rupiah from the usual manual method. This technique is quite effective and avoids the use of pesticides in the treatment of guava plants. The second topic is Green Synthesis of Graphene Oxide with Lycopene Reducing from Watermelon. Graphene-based supercapacitors will have a higher mass density compared to conventional dielectric capacitors, have a great ability to capture and store energy so that it can be used as a primary power source when combined with a battery or fuel cell. With graphene material, the supercapacitor will have 10 times more storage space than other materials. One method for synthesizing graphene oxide is Chemical Vapor Deposition (CVD) on Ni and Cu metals. However, this method is considered less efficient, requires relatively expensive costs, and is not environmentally friendly. Lycopene is a powerful antioxidant compound and has the ability to reduce it better. Watermelon fruit contains more lycopene than papaya and tomatoes, which is 12,962 miugram. Green synthesis of graphene oxide is done by reducing graphene oxide with lycopene reducing agents using the Hummer method, and characterizing reduced graphene oxide using FTIR spectrophotometer, XRD (X-Ray Diffraction), UV-Vis, and voltage testing with multimeters. The results of this study show the characteristics that correspond to standard graphene material and produce a voltage capacity of up to 140F / g. The advantage of this research is the principle of applying green synthesis so that it is more environmentally friendly, the materials used are easier to obtain and affordable, and the methods offered are easier than previous methods. This research is expected to be a solution for the procurement of the LCEV program and the launch of electric cars in Indonesia. “This research has won awards from South Korea and Taiwan”, said Wilda, the team leader 2.

The third topic discusses the treatment of NITROGEN PLASMA on the superhydrophilic properties of glass coated with polystyrene as a temperature-lowering building based on water evaporation. By modifying the surface of the glass, the glass can add power to contact with water so that it can reduce the workload of Air Conditioner resulting in electricity savings. The final topic is about Retinaldehyde Synthesis from Beta Carotene compounds in Dunaliella salina Mikroalga as Vitamin A precursors to support the Fortification Program in Cooking Oil. This is related to the Indonesian government policy which reduces the import of synthetic precursor of Vitamin A. “This research will have the opportunity to get a gold medal because it will be very helpful for the Indonesian government,” said one of the PIMNAS judges in debriefing and quarantine at the Savana Hotel on 18-20 August 2018 ago.

The FMIPA contingent received appreciation and full support from the PIMNAS jury team who attend to participate in the event. According to him, the title of the research developed by the FMIPA team had a real impact on the community. [yogie]
