Abstract

This research aims to determine the effect of variations in heating time and humidity of the E7016 electrode on the tensile strength of welded joints in SS400 material. The research was carried out using three humidity levels and two electrode heating durations (2 hours and 3 hours) at a temperature of 260°C. The research results show that electrode humidity and heating time have a significant influence on the tensile strength of the welded joint. The highest tensile strength value was found in the welding variation using welding wire without treatment with heating for 3 hours with an average of 529.62 N/mm2, then the lowest tensile stress was found in the outdoor electrode humidity treatment variation with a heating time of 2 hours amounting to 378.12 N/mm2. The analysis was carried out using the two ways ANOVA method to analyze the resulting tensile strength data. The analysis results show that electrodes heated for 3 hours produce higher tensile strength compared to electrodes heated for 2 hours

Abstract

Kinematics of Free Fall Motion (FFM) is one of the important chpaters in physics courses. However, the Physics Laboratory at the Department of Mechanical Engineering, State Polytechnic of Sriwijaya does not have practical tools of FFM yet. This study aims to design and determine the performance of the FFM physics lab based on the Internet of Things (IoT). This research method uses qualitative method and experimental approach. This physics lab is afterward compared to theoretical calculations from the FFM formula by testing it at 3 falling heights of 100 cm, 130 cm, and 150 cm, as well as at 3 different masses of 100 g, 200 g, and 500 g. All data collected need to be analyzed using ANOVA of linear regression to obtain the level of accuracy and the relationship between falling heights and masses towards final velocities of the test objects. The results of the study shows that the development of the lab physics FFM IoT-based has very decent performance as long as the average error percentage is 5.52% or less than 10% as well as the level of average accuracy level is 94.48%. The results of the analysis showed that falling heights have a significant effect towards final velocities of the FFM’s test objects. On the other hand, variety of masses barely has no effect towards final velocities of the physics lab.

Abstract

Friction Force on An Inclined Plane (FFIP) is one of the important chpaters in physics courses. This study aims to develop and determine the performance of the lab physics lab based on the Internet of Things (IoT). This research method uses qualitative method and experimental approach. This physics lab is afterward compared to theoretical calculations from the FFIP formula by using tests at 3 inclined plane’s angles of 30o, 45o, and 60o, as well as at 2 distances of 40 cm and 70 cm. The data were analyzed using ANOVA of simple linear regression to obtain the level of accuracy and the relationship between the inclined plane’s angles and the distance towards the kinetic friction coefficient of the test objects. The results of the study shows that the development of the lab physics FFIP IoT-based has very decent performance as long as the error percentage (average) is 4.77% or less than 10% as well as the level of accuracy (average) is 95.23%. The results of the analysis showed that the inclined plane’s angles have a significant effect towards the kinetic friction coefficient of the test objects. On the other hand, the distance barely has no effect towards the kinetic friction coefficient.
