The collaboration between Geophysics FMIPA UGM and Upstream Innovation PHE in its third year through Electrically Enhanced Oil Recovery innovation is poised to enter the field. This effort is aimed at supporting the government’s program to increase oil production targets by 1 million barrels by 2030 in Indonesia. The UGM Geophysics Research Team, along with Upstream Innovation PHE, actively contributes to achieving this goal.

“Through this research collaboration, our (FMIPA UGM) hope is to support the government’s target of 1 million barrels of oil production,” said Prof. Kuwat Triyana, Dean of FMIPA UGM, during the “Kickoff Meeting for the Electrically Enhanced Oil Recovery Collaboration Study in 2024” held via online meeting on Monday, Jan 12^th, 2024.

In 2023, initial field testing was conducted to assess the performance of the Electrically Enhanced Oil Recovery equipment. By continually improving the quality of this equipment, the UGM Geophysics Research Team and Upstream Innovation PHE are confident that they are ready to enter the field for broader oil production in 2024.

“We appreciate the trust placed in us over the past few years. We continue to strive in the development of this Electrically Enhanced Oil Recovery equipment to support the 1 million barrel production target in Indonesia,” said Dr. Afif Rakhman, head of the UGM Geophysics Research Team.

Electrically Enhanced Oil Recovery is one of the supportive methods in oil exploitation by injecting high-powered direct current (DC) into reservoirs to enhance production. By installing anodes and cathodes at specific distances and configurations, the electric current can alter the physical properties of the rocks it passes through, facilitating the movement of oil beneath the earth’s surface. The equipment developed by this team also features remote control capabilities through the internet network.

“This developed technology is easily implementable due to its relatively simple installation process and online operation, making it more effective and efficient in terms of time and cost,” said Metrik Pradana, initiator of the Electrically Enhanced Oil Recovery research from Upstream Innovation PHE.

The technological innovation built through collaboration between institutions and industry partners is an effort to support government programs, particularly in contributing to the achievement of Sustainable Development Goals (SDGs). This research collaboration reflects point 9 – Infrastructure, Industry, and Innovation, through innovation in meeting the country’s energy needs, as well as point 17 – Partnerships to Achieve Goals, through collaborative efforts to meet the goal of national oil requirements production.

The Geophysics FMIPA UGM collaborated with the Faculty of Tourism and the Faculty of Engineering of Udayana University (UNUD), along with the Mount Fuji Research Institute (MFRI) to organize a workshop and focus group discussion (FGD) as the annual flagship activity of the AGAA Project. The AGAA Project aims to enhance disaster preparedness on the slopes of volcanoes in Indonesia. The workshop and FGD activities occurred at the Lereng Agung Restaurant, Besakih Village, Menanga District, Karangasem Regency, Bali on Saturday Feb 3^rd 2024.

“This activity is expected to provide a platform for mutual learning from the experiences of speakers in disaster mitigation strategies, particularly volcanic eruptions,” said Dr. Wiwit Suryanto, the head of the AGAA project and a lecturer in Geophysics at the Faculty of Mathematics and Natural Sciences, UGM. The speakers included representatives from the Regional Disaster Management Agency (BPBD) of East Java (Mount Kelud and Semeru), North Sumatra (Mount Sinabung), West Sumatra (Mount Marapi), the Coordinator of the Disaster Risk Reduction Forum in Yogyakarta Special Region, and the Fujiyoshida City BPBD in Japan. Each speaker shared experiences from their respective regions in handling volcanic eruption crises and the contingency plans held by each area. This workshop and FGD are part of the AGAA Project funded by the Japan International Cooperation Agency (JICA) through a grassroots project scheme. The AGAA Project aims to build disaster-resilient communities by empowering local universities. This workshop and FGD represent the culmination of Year 2 activities in the AGAA project. Attendees this Saturday included the Karangasem Regency BPBD, local disaster mitigation enthusiasts grouped in the Karangasem Regency Disaster Risk Reduction Forum, and the headmasters of public elementary schools in Karangasem Regency. By participating in this event, the local community of Karangasem can directly learn from other volcano slope communities in Indonesia. Furthermore, the lessons learned from this one-day workshop and FGD can serve as a guideline for the Disaster Risk Reduction Forum (PRB) in the Karangasem Regency in preparing for future eruptions of Mount Agung.

Dr. Ade Anggraini, a geophysics expert and lecturer at UGM, led a focus group discussion on the Development of Local Platforms in building community preparedness on the slopes of Indonesian volcanoes

The demonstration of volcanic disaster mitigation teaching aids, created by MFRI Japan and the geophysics laboratory at UGM, was conducted by elementary school principals on the slopes of Mount Agung alongside MFRI staff

During this occasion, a simple experiment was demonstrated on the mechanism of volcanic eruption using basic teaching aids. The experiment was facilitated by staff from MFRI Japan and demonstrated by the school headmasters who had previously undergone training sessions from the AGAA Project in 2023 and 2024. The same teaching aids were also distributed to the Karangasem PRB Forum. They will be used as educational tools for the community to understand the mechanisms of volcanic eruptions in a simple yet scientifically accurate manner. Thus, it is hoped that the disaster mitigation learning of the Karangasem community regarding volcanic eruptions will continue and endure after the conclusion of the AGAA Project in 2025 in line with the implementation of the Sustainable Development Goals (SDGs). This activity aligns with SDG point 11 under pillar 5 on Sustainable Cities and Communities, particularly in reducing the adverse impacts of natural disasters. Point 11, pillar 5, relates to reducing the risk index, disaster prevention, preparedness, and post-disaster mitigation.

UGM Students Unveil Electric Motorcycle with 57% Domestic Content

Januari 11, 2024

The Gasbadra team at UGM has spearheaded research and development in Indonesia, focusing on creating electric motorcycles with an impressive 57.42% domestic component level (TKDN).

Dhamar Gumilang Panggayuh, the Gasbadra’s engineer, proudly shared the team’s achievement during a press discussion at the UGM Faculty of Mathematics and Natural Sciences on Thursday (Jan. 4).

“Our electric motor boasts a TKDN of 57.42%, surpassing the government’s target of 50% TKDN,” he declared.

The evolution of the electric motor has been ongoing since 2022, with the team continuously advancing various components under the guidance of the UGM Computer Science and Electronics Department lecturers. The project also receives support from PLN.

The Gasbadra team, led by Wisnu Aryo Jatmiko, has members Gilang Rizky Yunanto, Ferdian Arvin Nayandra, Alfahri Rifki Fahrezi, Heva Adlli Wijaya, Stefano Aldo Budi Satria, Rayhan Tegar Pamungkas, Muhammad Fakhri Ajrillah, Yuta Ilham Nugroho, Aulia Malik, Dhamar Gumilang Panggayuh, dan Faiz Yuda Anggoro–all are Electronics and Instrumentation students.

They diligently worked on crafting electric motorcycles to combat exhaust emissions from conventional fuel-based vehicles.

The team has delved into multifaceted research encompassing the frame, body, powertrain, and electric vehicle electronics, including the battery pack, power distribution, and BLDC controller.

“In our battery pack, we’ve incorporated a battery management system equipped with over-current, over-voltage, and short-circuit protection features to ensure battery safety,” explained Panggayuh.

Beyond safety, the Gasbadra team has prioritized efficiency and smooth starts for their electric motor. The team’s initiative aligns seamlessly with Sustainable Development Goal 7, which aims to achieve clean and affordable energy.

“In terms of electrical efficiency, our developed motor excels,” remarked Panggayuh.

Yuta Ilham Nugroho, another team member, highlighted that their electric motor’s range is comparable to other models on the market. However, it outshines competitors in producing a more powerful maximum output.

The team’s mid-drive DC brushless electric motor operates at 72V with a maximum current of 40A, delivering an impressive torque of 45Nm at 3000rpm and reaching speeds of 65-70 km/h with a max rpm of 4800.

The Gasbadra team has introduced two driving modes: eco mode and sport mode. In eco mode, the motor can cover an estimated 40 km on a single charge, emphasizing battery life.

On the other hand, sport mode prioritizes swift acceleration for a faster reach to the maximum speed. The estimated coverage in sport mode is up to 30 km.

“The fundamental difference in each mode lies in the acceleration curve. Sport mode reaches the maximum speed faster, while eco mode prioritizes battery life, offering smoother initial acceleration ideal for urban areas with flat terrain,” explained Nugroho.

The team has implemented a more responsive regenerative braking system in eco mode. When the throttle is released, regen brake activation produces reverse current, recharging the battery. The battery specifications include 84V 20Ah, requiring six to seven hours for a full charge.

“This electric motorcycle features a robust scrambler design, exuding a masculine aura tailored for terrain exploration. With a dual-purpose capability for road and off-road use,” he concluded.

Mahasiswa UGM Kembangkan AI dan AR untuk Perawatan dan Edukasi Kesehatan Gigi Anak

Oktober 5, 2023

Dalam upaya meningkatkan perawatan dan edukasi kesehatan gigi dan mulut anak-anak, Tim PKM Pi Universitas Gadjah Mada (UGM) telah merintis inovasi luar biasa yang diberi nama “Aplikasi Gigi Kecil”. Aplikasi ini menggabungkan dan mengimplementasikan teknologi Artificial Intelligence (AI) dan Augmented Reality (AR) untuk memberikan solusi atas permasalahan yang relevan dengan perkembangan zaman.

Aplikasi Gigi Kecil diinisiasi oleh tiga mahasiswa Pendidikan Dokter Gigi FKG, yaitu Dwina Aulia Ristyoningrum, Ariefa Nugrahany Nursalim, dan Ribka Wijayanti Kusnardi serta berkolaborasi dengan dua mahasiswa Ilmu Komputer FMIPA, yaitu Fitriansyah Eka Putra dan Khoirul Anam . Di bawah bimbingan drg. Mohammad Fadyl Yunizar, MPH., Ph.D., kelimanya mengembangkan aplikasi Gigi Kecil dengan pendanaan dari Program Kreativitas Mahasiswa Penerapan IPTEK (PKM-PI) Kemendikbud Ristek 2023.

Inovasi ini bermula dari permasalahan yang dihadapi RSGM UGM Prof. Soedomo dalam perawatan gigi anak. “Promosi kesehatan gigi anak yang dilakukan oleh RSGM UGM masih sangat terbatas, hanya melalui akun instagram dan website. Itu pun kami hanya memiliki sedikit konten edukasi kesehatan gigi anak,” tutur Humas RSGM UGM Prof. Soedomo saat berdiskusi dengan tim PKM PI. Selain itu, pihak RSGM juga menyatakan bahwa pasien anak sering mengalami ketidakberlanjutan perawatan. “Banyak pasien anak yang perawatannya putus di tengah jalan. Selama ini, tidak ada yang dapat memonitor perawatan pasien anak, terutama dalam perawatan jarak jauh”. Padahal, kesehatan gigi dan mulut anak sangat perlu diperhatikan. Gigi susu sangat mempengaruhi gigi permanen yang tumbuh. Apabila tidak terjadi ketidaksempurnaan dalam perawatan, maka akan mempengaruhi gigi permanen yang tumbuh.

Dari persoalan dan kekhawatiran tersebut dikembangkanlah aplikasi Gigi kecil yang merupakan aplikasi Android dengan fitur utama berupa Screening yang dapat mengidentifikasi karies pada gigi anak secara real-time dengan menerapkan artificial intelligence sebagai pendeteksinya. Ada pula fitur Ayo Belajar! Yang merupakan fitur edukasi berbasis augmented reality untuk membantu anak kecil memahami mengenai proses gigi berlubang. Aplikasi Gigi Kecil juga menyediakan fitur Kalender, Pengingat, dan Fitur Chat yang akan terintegrasi dengan RSGM UGM Prof. Soedomo.

Aplikasi ini telah diuji cobakan pada pembukaan Bulan Kesehatan Gigi Nasional yang diselenggarakan pada tanggal 12 September 2023 di FKG UGM dan RSGM UGM Prof Soedomo. Aplikasi ini mendapat antusiasme tinggi dari masyarakat, khususnya pasien anak rsgm UGM prof Soedomo. Melalui uji coba ini, terbukti banyak pengunjung Ibu yang memiliki anak terkesan dengan fitur yang dimiliki aplikasi ini, terutama konsultasi gratis dengan dokter gigi profesional. Sedangkan, pasien anak langsung menyukai permainan edukasi berbasis augmented reality yang menjadi andalan aplikasi ini. Tidak hanya itu, banyak Staff RSGM Prof. Soedomo yang merasa terbantu dengan adanya aplikasi ini. Mereka sangat berharap, dalam perkembangan selanjutnya, aplikasi ini mampu terintegrasi seutuhnya dengan manajemen rumah sakit sehingga digitalisasi pelayanan kesehatan dapat membawa keefektifan dan keefisienan sistem rumah sakit.

Dengan adanya aplikasi ini, diharapkan masyarakat akan lebih teredukasi akan pentingnya kesehatan gigi anak, terputusnya perawatan kesehatan di RSGM Prof. Soedomo akan berkurang, serta pelayanan kesehatan gigi dan mulut dapat optimal. Adanya aplikasi ini menjadikan RSGM. Prof. Soedomo sebagai satu-satunya Rumah Sakit Gigi dan Mulut yang memiliki aplikasi digital. Ditambah lagi, aplikasi ini bukan hanya untuk pendaftaran online, tetapi mampu mengedukasi serta memantau selama periode perawatan gigi dan mulut anak. Melalui aplikasi ini, kualitas kesehatan gigi dan mulut anak Indonesia akan meningkat!

Tim PKM-PI saat ini dalam tahapan mengunggah Aplikasi Gigi Kecil ke Google PlayStore, namun masyarakat dapat mencoba menggunakan Aplikasi Gigi Kecil melalui laman alternatif yang disediakan yaitu https://linktr.ee/gigikecil. Melalui Aplikasi Gigi Kecil mereka berharap dapat membantu RSGM UGM Prof. Soedomo dalam mempromosikan serta mengedukasi masyarakat mengenai kesehatan gigi anak.
