[vc_row][vc_column][vc_column_text css=””]The Meteorology, Climatology, and Geophysics Agency (BMKG) together with Gadjah Mada University (UGM), University of Indonesia, and Bandung Institute of Technology (ITB) are developing an earthquake and tsunami monitoring system through research called System Processing Development of InaTEWS Merah Putih as an implementation of IDRIP (Indonesia Disaster Resilience Initiatives Project). In order to review the research process, the BMKG consisting of PIU IDRIP, PPK IDRIP, and BMKG Technical Team visited the UGM Geophysical Laboratory on Wednesday (24/04).
‘To review the progress and obstacles, we need a lot of discussion and input so that the desired target in this research can be achieved.’ said R. Agung Prasetyo as PPK IDRIP when interviewed by UGM Geophysical Media. This is also one of the reasons for the BMKG team’s visit to UI, ITB, and UGM on this occasion to discuss the sustainability of InaTEWS Merah Putih.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”13292″ img_size=”large” css=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=””]

‘The BMKG itself still uses foreign-made software to process earthquake data, so we want to produce a processing system developed by Indonesia. Thus, it is called ‘Merah Putih’ which is the identity of our country,’ Agung continued.
Being independent in earthquake processing technology research is a step that is being pursued by Indonesia. This is done in order to minimise risks and expand capacity in facing the threat of earthquakes and tsunamis, especially in densely populated areas in Indonesia. In line with Sustainable Development Goals (SDGs) point 11, namely Sustainable Cities and Settlements, more advanced and independent earthquake processing technology will create community resilience in facing earthquake and tsunami disasters.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_gallery type=”image_grid” images=”13287″ img_size=”100 x 100″ css=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=””]Author : Shofi Rahmadini K

[vc_row][vc_column][vc_column_text css=””]Rebon Seminar is one of the regular activities of the Department of Physics, as a place to discuss and exchange ideas about research, studies and phenomena according to the Field of Study Groups in Physics UGM. On 3 April 2024, the Rebon Seminar carried a theme around the world of oil and gas with the topic ‘Non Seismic Geophysical Methods for Oil and Gas Activity’ presented by Boko Nurdiyanto Suwardi, M.Si. as Sr. Specialist Innovation Geophysics Upstream Innovation Pertamina Hulu Energi. This seminar was held online via Zoom Meeting and moderated directly by the Coordinator of KBK Geosciences, Dr.rer.nat. Ade Anggraini, S.Si., M.T.

The seminar began with sharing related to the upstream process in the modern oil and gas industry which consists of exploration and production activities. The series of activities include geological studies, geophysical studies, seismic drilling to the development of production wells, which of course takes a lot of cost and time (>10 years). Geophysics itself is a study of the earth using physics. In its application, geophysicists study the nature or physical characteristics of rocks with methods such as reflection seismic, refraction seismic, gravity, magnetic, electromagnetic, and so on, to then interpret subsurface conditions.  

Broadly speaking, there are four classifications of geophysical methods: gravity, magnetic, seismology, electrical and electromagnetics. In seismology, there are reflection seismic and refraction seismic methods, both of which are very popular for oil and gas exploration activities. In reality in the field, there are many poor surface conditions that become obstacles in applying seismic methods. This underlies the need for integration of seismic methods with other (non-seismic) geophysical methods.

Entering the production phase, geological and geophysical data is required for drilling development (additional production wells). One example of a method being developed with Geophysics UGM in this process is the Controlled Source Audio-frequency Magnetotelluric (CSAMT) method. This method is used as a Direct Hydrocarbon Indicator through electromagnetic survey, which produces output in the form of resistivity data well logs. Examples of other methods that are still under development for the production phase include: Transient Electromagnetic (TEM), Low Frequency Passive Seismic, Thermal Method, and Gradient Vertical Gravity.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”13212″ img_size=”large” alignment=”center” css=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=””]

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=””]‘The development of other geophysical methods is quite slow even though the potential to explore is quite large, hopefully educational institutions will also develop methods other than seismic such as electrical and electromagnetics with funding efforts from institutions and industries,’ said Boko. This integrated geophysical method approach will be much more powerful in solving complex problems encountered in oil and gas exploration and production activities.

Sharing about the twists and turns of oil and gas development through this Rebon Seminar is an effort that supports the achievement of the 4th pillar, 9th pillar, and 17th pillar of the Sustainable Development Goals relating to quality education, inclusive and sustainable industries and partnerships to achieve these goals. Participants were invited to recognise and participate in developing non-seismic geophysical methods to support and improve the oil and gas inclusive industry in Indonesia. This seminar is also expected to strengthen research bonding between Geophysics UGM and Pertamina Hulu Energi to continue to innovate that is useful for sustainable development and global citizenship and partnership.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_gallery type=”image_grid” images=”12943,13213,12944″ img_size=”100 x 100″ css=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text css=””]Author: Rafida Salma Rahmawati

[vc_row][vc_column][vc_column_text]Rebon Seminar is one of the routine activities of the Physics Department, as a place to discuss and exchange ideas about research, studies and phenomena according to the Group of Expertise in Physics UGM. On March 27, 2024, the Rebon Seminar carried a theme around medical physics with the topic “Nanophotosensitizer with Natural Bioreductants to Increase the Efficacy of Antibacterial Effects” presented by Prof. Dr. Suryani Dyah Astuti, M.Si. from Airlangga University as a guest speaker. She is a recipient of government assistance in the First Wave Matching Fund Program in 2021 with the program title “Acceleration of Production and Teaching of Dentolaser Industry as Efforts to Improve the Domestic Medical Equipment Industry in the Field of Dentistry”. This seminar was conducted online via Zoom Meeting and moderated directly by the Coordinator of the Applied Physics Study Group, Prof. Dr. Mitrayana, S.Si., M.Si.

The seminar began with a sharing session about ongoing research activities at Airlangga University, namely Nanophotosensitizer, which is a substance used to absorb light energy that will subsequently be used to enhance efficacy, especially against pathogenic microorganisms such as bacteria or fungi. The presence of antibiotic resistance in infected wounds caused by bacteria highlights the urgency of research development in the form of Photodynamic Inactivation. Photodynamic Inactivation is a non-invasive photon-based therapy that includes several functions, such as killing bacteria or infection-causing biofilms, as well as regenerating cells and accelerating wound healing processes.

Photodynamic Inactivation is a therapy method that utilizes light and a photosensitizer (non-toxic molecule). Photodynamic Inactivation is not only used to kill microbes such as bacteria but can also be employed in cases like tumors or cancer. The light energy utilized is non-ionizing and safe for healthy tissues. The light used is part of Low-Level Laser Therapy (visible light and infrared), where the wavelength has been adjusted to match the depth of wound penetration in the skin.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”13087″ img_size=”large” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]

Presentation of speakers related to the mechanism of photodynamic inactivation which consists of photophysics, photochemistry, and photobiology processes.

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]“For now, research on the development of photosensitizers is already in the downstream product process stage but still in the photodynamic therapy corridor,” said Prof. Dr. Suryani Dyah Astuti, M.Si. There are four stages of product downstreaming, including making prototypes, followed by lab scale tests, clinical trials, finalized by the standardization process, certification, and market tests.

The sharing about photosensitizer innovation in the field of medical physics through this Rebon Seminar is an effort that supports the achievement of Sustainable Development Goals number 3, 4, and 17 related to good health, quality education, and partnerships to achieve these goals. Participants are invited to collectively recognize the applied physics knowledge that supports research and development in the medical field to achieve universal health coverage. Indirectly, through this seminar, relationships among researchers, both students and faculty, can also be built to continue innovating, which is beneficial for sustainable development, citizenship, and global partnerships.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_gallery type=”image_grid” images=”13089,12943,12944″][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Author: Rafida Salma Rahmawati

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]“Why does this research need to involve the public, rather than just using AI?” remarked one of the participants during the Q&A session. Dr. Itsna Khoirul Fitriana explained that the Galaxy Cruise Project itself is an interactive form of education for the public through enjoyable gaming. So far, the use of AI, specifically Deep Learning, has been developed but still relies on dim telescope data and is still misclassified (weak feature). Therefore, a new system called ECSI has been developed which involves community classification. Within the ECSI system, AI (Machine Learning) has also been developed but still needs to be validated with visual inspection requiring assistance from the public as a library. This library is currently being constructed through the Galaxy Cruise Project.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”12942″ img_size=”large” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
