Abstract

This study aims to analyze the effect of current variations on the V seam with a seam angle of 37.5° on the testing of mechanical properties and the appropriate welding method as a connector for two API 5L X52 materials using the Shielded Metal Arc Welding (SMAW) welding method. The current variation used is (70, 100, 115 A) in Sample A, the current variation is (70, 120, 130 A) in Sample B, and the current variation is (70, 125, 130 A) in Sample C. After the welding process is carried out, the samples are then tested for tensile, bending, observing macro structures, and microstructures. The test results obtained the highest value of tensile testing on current variations (70, 125, 130 A) with a value of 715.4 MPa, while the lowest value on current variations (70, 100, 115 A) with a value of 596.66 MPa. The results of the bending test show that the highest value is obtained in the current variation (70, 125, 130 A) with a value of 1417.93 MPa, while the lowest value is obtained in the current variation (70, 100, 115 A) with a value of 1289.01 MPa. The results of metallographic testing showed that the microstructure data on variations in the welding current strength of (70, 100, 115 A), (70, 120, 130 A), and (70, 125, 130 A) resulted in a phase that composed of ferrite and pearlite. The microstructure formed is influenced by the magnitude of the welding current used. The results of macro observations obtained porosity in the weld metal area.

Abstract

Every year, a program called a "tracer study" is run to collect and analyze data from graduates (a year after graduation). Seeks to guarantee that graduates have good work and submit it on time following university or institute criteria after graduation. Within 1-2 months of filling it out, a data analyst processes the data and validates its accuracy. Data for 10 study programs were collected, and comparisons were made between the graduation years of 2019 and 2020. In 2020, the Covid-19 pandemic started. The Institut Teknologi kalimantan (ITK) was significantly impacted by Covid-19, which led to all work being done online on campus. Evaluation criteria for ITK include the length of time it takes graduates to find employment, their GPA, the nature of their alumni employment, and their reasons for not finding employment one year after graduation. In order to be able to create more qualified alumni, the rate ranking approach will help examine the success of the study program and provide an evaluation of the study program. This paper's two lowest-ranking disciplines are electrical engineering, materials engineering, and metallurgy..

Abstract

Noncommunicable diseases (NCDs) are common in Indonesia; this is also true in Karang Jati, Balikpapan, and East Borneo. Despite this, the villagers have little knowledge about prevention, despite being aware of the grave consequences that diseases can have on their well-being and social standing. This exercise aims to raise villagers' understanding of the need to prevent non-communicable diseases. Using NCD screening with information distribution, this activity has encouraged the villagers to become more aware of the condition and motivated them to take preventative action. Most of the villagers are at high risk of noncommunicable diseases (NCDs), specifically hypertension, according to the screening results. These data have effectively supported the villagers in establishing NCD screening and management in their neighborhood through Pos Pembinaan Terpadu (Posbindu) PTM, a community-based NCD prevention and management activity.
