IO, Surabaya – A brilliant achievement was once again brought home by Ten November Institute of Technology (ITS) students. In the Lean Construction Competition (K2R) 4.0, ITS, represented by the Department of Civil Engineering (DTS) student team, succeeded in winning the first two places in the annual competition held by the Bandung Institute of Technology (ITB), last Saturday.
The first prize was in the Total Performance and Minimal Waste category. With the acquisition of the first two prizes, ITS was named overall champion. The Ascarya team members were Zhafira Aulia KA (undergraduate class 2016 students), Davin Atmaja L (S1, 2017), William Bunkharisma (S1, 2017), M Arif Ramapramudya (S1, 2018), Alfya Natasya D (S1, 2018), Erfandi Zen V (S2, 2019), and Freedy Kristawan (S2, 2018).
The seven students competed closely with other participants to design and process construction prototypes with Lego main material (small plastic chunks that can be designed to form anything-Ed).
K2R 4.0 is a competition with a focus on implementing lean construction. The emphasis is on total performance efficiency and minimal waste of materials. The event is meant to increase people’s understanding of lean construction; it has been held regularly every year since 2016.
Freedy, a member of the Ascarya team, said that in this race their team was divided into two positions. One person acts as the main contractor, while six other colleagues become subcontractors. Freedy and the team were given a design drawing that would be processed in collaborative pull planning (a collaborative process to find scheduling plans by all participants). “In this case, we also have to design building prototypes based on the plan,” said the young man from Surabaya, in a release received by the Independent Observer.
Freedy and his team recorded the material requirements and purchased the required materials. They installed the existing Lego material until the prototype was successfully realized. Total performance, material waste (excess Lego when ordered but not installed), installation errors, and other specified violations by the Ascarya team were counted.
Innovations by the Zhafira-led team: when installing the layers, the team did them quickly and precisely. There was no waste material produced by Ascarya’s design construction because they did not do construction by layer, but rather maximized the number of floors that could be worked on. “The team completed three floors in one run,” he said.
Freedy added coordination was the most important aspect in winning. Before ordering materials, they performed an internal check between themselves with the number of Legos to be installed. “So, in the end, we managed to design a construction consisting of ten floors,” he said.
Cahyono Bintang Nurcahyo ST MT, a team supervisor, stated that he was very pleased with the overall performance of Ascarya. This Civil Engineering lecturer said that their success was the result of hard work and commitment of the team that had gone through intense selection and training for the past two months. “I appreciate their enthusiasm and efforts to achieve the best results this year,” he said.
Compared to the previous year’s competition, this team had to struggle more to overcome technical and mental obstacles with relatively tight preparation. However, thanks to the availability of the question bank and the successful transfer of knowledge from the previous team, the above obstacles could be overcome.
This University of Indonesia alumnus believes that DTS will always try to give the best in each competition. Therefore, a team regeneration is needed to transfer knowledge every year. “In 2018 we won first place in the Total Performance category and third place in the Minimal Waste category; in the future we are confident that we can maintain this and increase achievements in many other competitions,” he added.
