The activity began with opening remarks from Prahasdipta Bayu Adhi Koesoemo, Head of Dam Management Unit (UPB) I of the BBWS Ciliwung Cisadane, along with representatives from the Geology Study Program of FMIPA UI. During the session, both parties emphasized the importance of collaboration between higher education institutions and infrastructure management agencies in advancing the development of applied geology in Indonesia.<\/p>\n\n\n\n
\u201cField-based learning is an essential component in preparing human resources capable of addressing future challenges in water resource management,\u201d said Prahasdipta Bayu Adhi Koesoemo<\/p>\n\n\n\n
\u201cDams are not only flood-control infrastructure but also excellent learning facilities for understanding how geology, geotechnics, and engineering work in an integrated manner. We hope that students can directly observe the practical application of the knowledge they learn in the classroom while gaining a deeper understanding of the real-world challenges involved in managing hydrological disaster risks in Indonesia,\u201d said Bayu.<\/p>\n\n\n\n
The program continued with a public lecture featuring several speakers from the BBWS Ciliwung Cisadane and dam engineering experts. The first session, titled \u201cThe Philosophy of Floods,\u201d was delivered by Rafii, Advisor to BBWS Ciliwung Cisadane.<\/p>\n\n\n\n
In his presentation, Rafii explained that floods are a natural part of the hydrological cycle. The primary challenge is not to eliminate floods entirely, but rather to manage their risks and impacts through effective planning, adequate infrastructure development, and increased public awareness.<\/p>\n\n\n\n
\u201cFloods cannot be completely avoided, but their risks can be managed through proper planning and preparedness,\u201d said Rafii<\/p>\n\n\n\n <\/p>\n\n\n\n Next, Prahasdipta Bayu Adhi Koesoemo presented the flood management system based on the dry dam concept implemented at the Ciawi and Sukamahi Dry Dams. According to him, dam planning must take into account a wide range of flood scenarios, from events that recur every few decades to the Probable Maximum Flood (PMF)\u2014the largest flood event that could theoretically occur under the most extreme hydrological conditions.<\/p>\n\n\n\n He explained the concepts of 50-year floods, 100-year floods, and the Probable Maximum Flood (PMF), which serve as key references in determining dam capacity and safety standards. These flood scenarios form the basis for designing and operating dams to ensure they can effectively withstand and manage potential extreme flood events.<\/p>\n\n\n\n \u201cDams must be designed to withstand a wide range of scenarios, including the most extreme flood events that could potentially occur,\u201d he said.<\/p>\n\n\n\n The next session focused on the geotechnical aspects of dam engineering, presented by dam engineering expert Buhori. He explained that geotechnics forms the fundamental basis of dam construction. A comprehensive understanding of soil and rock characteristics is essential to ensure that dam structures meet safety standards and perform effectively over the long term.<\/p>\n\n\n\n \u201cThe success of a dam begins with a proper understanding of the soil and rock conditions at the construction site,\u201d said Buhori.<\/p>\n\n\n\n Following the public lecture sessions, the students conducted field observations at several strategic locations within the dam complex. At the first site, located at the inlet area of the Ciawi Dry Dam, participants examined the flow of water through the dam structure and studied the local geological conditions, including rock outcrops exposed along the dam walls.<\/p>\n\n\n\n <\/p>\n\n\n\n The visit then continued to the crest area of the Ciawi Dry Dam. At this location, students received explanations regarding the dam\u2019s monitoring and maintenance systems, which play a crucial role in ensuring structural safety and the long-term sustainability of the dam\u2019s functions.<\/p>\n\n\n\n After a break, the activity continued to the Sukamahi Dry Dam. At the third site, located in the crest area of the dam, students studied the differences in construction methods and technical challenges between the Ciawi and Sukamahi dams. Buhori explained that the fill materials for the Sukamahi Dam were sourced from outside the local area due to differences in design slope steepness compared to the Ciawi Dam.<\/p>\n\n\n\n The activity concluded with a visit to the spillway of the Sukamahi Dry Dam. At this location, students studied the water overflow mechanism during high flood discharge events and the function of the spillway in preventing overtopping, which could threaten the structural stability of the dam.<\/p>\n\n\n\n Through this field lecture, students not only gained direct hands-on learning experience in the field but also developed an understanding of how engineering geology, geotechnics, and hydrological disaster mitigation concepts are applied in national strategic infrastructure. This experience is expected to broaden students\u2019 perspectives on the role of geological science in supporting water resource management and disaster risk reduction efforts in Indonesia.<\/p>","protected":false},"excerpt":{"rendered":" Depok, 2 Juni 2026 \u2014 Di tengah meningkatnya frekuensi cuaca ekstrem dan ancaman banjir di berbagai wilayah Indonesia, pemahaman mengenai geologi teknik dan pengelolaan sumber daya air menjadi semakin penting.
