Feasibility of Welding Technology E-Modules to Analyze The Strength of Welded Joints

One of the competencies that graduates of the Mechanical
Engineering Education Department must have is to be able to analyze the
strength of a weld joint.Increasing student competence in analyzing the
strength of welded joints, as a reference, a feasible and practical
instructional media is needed. Instructional media that specifically analyzes
the strength of welded joints are not yet available at the Department of
Mechanical Engineering Education ofUnimed, so this Instructional media is
developed which specifically analyzes the strength of welded joints.
Instructional media is developed in electronic form (e-modules) to make it
more practical in use.
Purpose - The purpose of this study was to determine the feasibility of
welding e-modules. Feasibility can be determined through the e-module
development process.
Design/methodology/approach - The e-module development uses the
research and development (R and D) method from Borg and Gall. The steps
for developed e-modules use the ADDIE model (Analysis, Design,
Development, Implementation and Evaluation), namely (1) Needs analysis,
(2) Planning and formulating learning objectives. (3) Development in the
form of making modules (4) Feasibility of e-modules through validation by
material experts, media experts and instructional design experts.Data
collection techniques were carried out by distributing questionnaires and
observations.
Findings- This study resulted in (1) evaluation of material experts that
the technology subject matter was included in the very feasible criteria with
an average score of 4.30. (2) The learning design expert's assessment is
included in the very feasible criteria with an average score of 4.20. (3) the
evaluation of instructional media experts falls into the feasible criteria with
255
an average score of 4.03, (4) an increase in the value of student learning
outcomes by 7 5. 50%, this proves that e-module technology is suitable for use.
Research limitations - The research subjects were limited to 5th
semester students of the Department of Mechanical Engineering Education
ofUnimed.
Originality/value - The welding technology e-module was developed
oroginally because it has never been developed by other researchers and has
been proven to improve student competence in analyzing the strength of
welded joints.
