Pengukuhan Prof. Dr. Chairil Anwar: Kemajuan Dan Tantangan Kimia sebagai Sentral Sains

Sains telah memberikan pengaruh yang sangat besar dalam kehidupan kita, khususnya dalam beberapa abad terakhir. Terlepas dari pencapaian yang fenomenal, sains saat ini menghadapi banyak tantangan yang mengancam keberlanjutan masa depannya. Ketika penemuan ilmiah terus hadir dan menyatu dalam masyarakat, akan semakin banyak tantangan yang menghadang. Kimia sebagai salah satu ilmu kealaman (natural sciences) yang sudah tua dan mature/matang, sering kali dianggap sudah mencapai titik puncak. Sesuai dengan hukum alam, apapun yang sudah mencapai puncak suatu saat akan mengalami penurunan. Namun, dalam kenyataannya kimia terus mengalami revitalisasi terutama karena berinteraksi dengan disiplin ilmu lain sehingga melahirkan ilmu baru. Demikian pernyataan Prof. Dr. Chairil Anwar saat dikukuhkan sebagai Guru Besar Fakultas MIPA UGM, Selasa (15/3/2022).

Dalam pidato ilmiah yang berjudul “Kemajuan dan Tantangan Kimia sebagai Sentral Sains”, Prof. Chairil Anwar menyampaikan bahwa kimia telah menembus banyak sisi kehidupan kita. Keterkaitan dan interaksi disiplin ilmu dengan industri, politik, dan masyarakat telah lama menjadi pokok dalam sejarah sains, sejarah teknologi, dan studi sains, meskipun dapat dikatakan bahwa dampak dari jalinan ini belum cukup dieksplorasi. Kimia adalah contoh kasus yang ideal, mengingat bahwa kimia telah muncul sebagai salah satu disiplin ilmu terbesar, sementara pada saat yang sama menjadi salah satu teknologi paling kuat di dunia. Secara khusus, kekuatan kimia terletak pada kemampuannya untuk memperoleh pengetahuan tentang alam dan kemudian mengubahnya, bersama masyarakat di mana kimia berada bersama.

Prof. Chairil Anwar menambahkan, pada sisi yang lain, aplikasi kimia yang ditemukan dan diperkenalkan terus bertambah dan meliputi banyak bidang. Misalnya, penemuan suatu material akan terkoneksi dengan berbagai bidang. Dalam konteks material, menarik untuk diikuti prospek pemanfaatan material karbon tabung nano berdinding tunggal. Molekul dengan bentuk geometris elegan ini diprediksi akan mendorong revolusi dalam elektronik, komputer, kimia, dan bahan struktural baru, khususnya sebagai alternatif pengganti perangkat elektronik dengan chip berbasis silikon yang sejauh ini menjadi material utama yang paling banyak digunakan. Selain itu, irisan kimia dengan bidang energi cukup besar. Energi menjadi salah satu kebutuhan utama manusia. Ada dua jenis energi utama, yaitu energi berasal fosil utamanya minyak bumi, gas, dan batu bara disebut energi tidak terbarukan dan energi non fosil (antara lain: biomassa, hidro, matahari, panas bumi, angin, kimia/baterai, dan nuklir) disebut energi terbarukan. Indonesia memiliki hampir semua sumber energi tersebut, sehingga kimia sebagai sentral sains dapat berperan besar dalam kemajuan dan kesejahteraan bangsa.

Initiation of Collaboration with Borobudur Conservation Office

Cultural heritage is an invaluable asset of the Indonesian nation. Efforts to preserve cultural heritage need to be made to maintain the integrity of these cultural treasures. One essential aspect of preserving cultural heritage, especially temples, is to understand the patterns and environmental conditions’ impact on the temple, such as vibrations, chemical reactions from natural processes, etc. For this purpose, an initiation of collaboration between FMIPA UGM and the Borobudur Conservation Office was carried out on Tuesday, January 25, 2022. The collaboration is planned to involve various fields of expertise and be integrated with research and community service activities.

Pakar UGM Ingatkan Bahaya Banjir Bandang Pasca Erupsi Gunung Semeru

UGM experts have warned of secondary or indirect dangers resulting from the eruption of Mount Semeru. In addition to the eruption and pyroclastic flow that occurred on December 4th, there is a potential for secondary hazards such as flash floods carrying volcanic material in upstream areas.

“Even though the eruption has ended, the potential for disaster threats still exists. In December, January, and February, we need to be aware of the potential for lava flows and possible subsequent eruptions,” said Dr. Danang Sri Hadmoko S.Si., M.Sc., a Faculty Member of the UGM Geography Department, during a press conference at the FMIPA UGM Auditorium on Monday (6/12).

He explained that the La Niña phenomenon is bringing the potential for heavy rainfall, so people in areas with rivers originating from Mount Semeru need to be cautious. Residents should also avoid activities within the designated danger radius established by local authorities.

“Some rivers originating from Semeru need to be monitored so that when lava flows occur in the middle and lower parts, where many settlements are located, lives can be saved,” he said.

He also pointed out that there is a potential for hot materials, so evacuation processes need to be carried out carefully and involve parties with an understanding of the volcano’s conditions.

Residents in the eruption-affected areas are advised to wear masks and protective eyewear to avoid health hazards from volcanic ash, which contains silica and is of micro size.

Dr. Wahyudi, M.S., a UGM Geophysics expert, explained that since 2012, Mount Semeru had been classified as Level 2 or “Waspada” (Watch). Then, in September 2020, signs of activity were observed in the form of white and gray smoke plumes reaching heights of 200-700 meters above the peak of Semeru.

Similar activity continued in October 2020, reaching heights of 200-1000 meters, and on December 1, 2020, a pyroclastic flow occurred, extending 2 to 11 kilometers southeast toward Kobokan. In the last 90 days, there has been an increase in seismic activity, especially volcanic earthquakes.

“Some reached 100 times a day, which can serve as a precursor to a larger eruption,” said Wahyudi.

According to Wahyudi, the collapse of the lava dome triggered by heavy rainfall led to the occurrence of the pyroclastic flow, which traveled quite a distance, reaching 11 kilometers. Scientifically, heavy rainfall can cause instability in lava deposits.

“In some cases, external factors like heavy rainfall can indeed cause thermal stress and trigger instability within the lava dome. The lava dome becomes unstable, and the presence of heavy rainfall triggers landslides,” he explained.

To determine the dominant factors causing the eruption on December 4th, he suggested conducting an integrated data analysis covering volcanic earthquake data, deformation, gas emissions, and rainfall data over the past few months. These data should be correlated with events, including small and large-scale collapses.
