The team from ITS Civil Engineering Department with their trophies at the closing of 2021 KJI & KBGI at Politeknik Negeri Pontianak, West Kalimantan

ITS Campus, ITS News – Good news arrived again at the academic community of Institut Teknologi Sepuluh Nopember (ITS). This time, the team from ITS Civil Engineering Department won two trophies and also the title of General Champion in 16th Kompetisi Jembatan Indonesia (KJI) or Indonesian Bridge Building Competition. The team also won two trophies at the 12th Kompetisi Bangunan Gedung Indonesia (KBGI) or Indonesian Structure Building Competition hosted by Politeknik Negeri Pontianak, West Kalimantan, Sunday (7/11) night.

The Head ITS Civil Engineering Department, Umboro Lasminto ST MSc, said that there were three competitions that the ITS Civil Engineering Department team participated in this most prestigious event for Civil Engineering students throughout Indonesia. At KJI, ITS participated in the Steel Frame competition. While in the KBGI, ITS participated in the Cold Rolled and Wood competition. “Two of the three competitions were successfully won by the ITS team; all teams have tried their best,” he said.

Umboro continued, Team Haga is the first winner in the KJI Steel Frame Bridge competition. Their members are Ricardo Fransiskus Karo-Karo and Ganjar Ageng Wicaksono Siswono, who won 1st place and the Sturdy Steel Frame category. These achievements also led the ITS team to become the General Champion at KJI. “At KJI, the ITS team has the most winners, so they get the title of General Champion,” he added proudly.

A member of the Haga team, Ricardo, said that there were three categories of assessment at KJI, particularly the Most Beautiful Bridge, Sturdy Steel Frame, and Bridges with Conformity between Implementation and the Best Initial Design. The bridge’s sturdiness is an essential point with a more excellent value than the others. “Here, we are required to make our models. For KJI, we did the fabrication at ITS first and then brought it to Pontianak and assembled it there (Pontianak, ed),” he explained.

The bridge model assembled on site is given a load of 60 kilograms in the middle of the span. Then, the deflection of the bridge is measured using two dial gauges or transducers. The deflection on the bridge made by the Haga team has the smallest deflection value among the seven other universities. “The deflection is below 0.5 millimeters, so we won the Sturdy Bridge category, won 1st place, and because we have the most winners at KJI, we also won the General Champion title here,” said the 2019 student.

Meanwhile, for the KBGI Model of Cold Rolled Steel-Story Building, ITS was represented by the Fukuro Team consisting of Andy Adhyaksa and Farhan Natanagara. This team not only won 1st place but also won the Seismic Performance category. In this competition, the judges assessed five categories: Creativity in Design, Suitability of Implementation to Design, Seismic Performance, Construction Implementation Methods, and Environmentally Friendly, Sustainable, and Earthquake Resistant Future Buildings.

Andy explained that ITS got the highest score in the Seismic Performance category, which has an enormous weight, 25 percent. In this category assessment, the building model is tested by vibrating on a vibrating table with a frequency of 1.5 Hz, 2.5 Hz, 3.5 Hz, 4.5 Hz, and 5.5 Hz with an amplitude of 10 millimeters and a frequency of one minute.

The slick model design from the Fukuro team managed to get the most significant residual deviation without collapse. “Because of that, this category got the highest score; the score was so extraordinary that we could get the 1st place,” he said.

Of course, this victory did not come without struggle, starting from selecting proposals to being able to advance to the final stage against other universities. Several challenges are present, such as the short model assembly time. For KJI, the ITS team is in fifth place and at KBGI in first place in completing the assembly. The ITS team remains optimistic and continues to work hard to win various trophies.

Ricardo hopes that the ITS team can be more competent in the years to come and continue to improve their enthusiasm in various competitions. “In the future, hopefully, we can achieve what cannot be achieved now and can continue to make our alma mater proud,” he said encouragingly.
