Hi, my name is Satrio Gumilar, my friends usually call me Gilar, I am 23 years old and I am a fresh graduate from Diponegoro University with a Bachelor of Mechanical Engineering study program with a GPA of 3.24 and a study period of 4 years and 7 months. During my college years I participated in several organizations such as the Mechanical Student Association and the Kebumen Student Association at Diponegoro University. In early 2018 , when I was in college, I participated as a committee for the publication and documentation division at the annual student meeting. While in 2019 I participated in many committees such as being part of the publication and documentation division at student sports week activities, then becoming a mechanic in free car and motorcycle service activities in collaboration with Nasmoco and Yamaha, and also being part of the security division at mechanical cup and mechanical stocks. At the beginning of 2020 when Covid-19 hit I decided to fill my free time to work part time at a coffee shop in my city, at the beginning of work I became a barista and at the same time was trusted by my boss to be in charge of the quality of drinks and also as a team leader for the drinks section. The experiences I got while doing this part-time job were regarding leadership, responsibility, good communication with customers, problem solving, accustomed to working under pressure and several other experiences. and I decided to stop at the beginning of 2023 so I could focus on completing my thesis. At the beginning of 2022 , I also took part in the thematic KKN activities held by Diponegoro University to help the economic recovery of residents in Lumajang district after the eruption of Mount Semeru at the end of 2021. The work program that I carried out was to educate local residents about making interlock bricks starting from making efficient and safe printers to the drying process until they are ready to install.
