requires appropriate process parameter settings to produce a consistent sealant bead&#13;
diameter within the specified limits. Improper parameter settings can cause&#13;
diameter variation, increase the risk of process failure, and lead to material waste&#13;
during machine setup. This study aims to identify the effects of pump pressure,&#13;
robot speed, and nozzle height on sealant bead diameter, determine the optimum&#13;
combination of process parameters, and evaluate process capability under the&#13;
optimum conditions. The Taguchi method with an L9 Orthogonal Array was&#13;
employed using the Nominal is Best quality characteristic. The experiment used&#13;
sealant with a viscosity of 75 Pa.s and an SNA-15G nozzle with an internal diameter&#13;
of 1.43 mm. The investigated factors consisted of pump pressures of 0.1, 0.2, and&#13;
0.3 MPa; robot speeds of 50, 75, and 100 mm/s; and nozzle heights of 1, 1.5, and 2&#13;
mm. The Signal-to-Noise Ratio analysis showed that pressure was the most&#13;
dominant factor, with a delta value of 12.047, followed by nozzle height at 7.641&#13;
and robot speed at 7.101. Based on the means analysis, pressure was also the most&#13;
dominant factor, with an ANOVA contribution of 53.48%. The optimum process&#13;
parameter combination was obtained at a pressure of 0.1 MPa, a robot speed of 100&#13;
mm/s, and a nozzle height of 2 mm, with a predicted S/N Ratio of 23.5566 and a&#13;
predicted mean bead diameter of 1.11847 mm. Furthermore, process capability&#13;
analysis under the optimum conditions resulted in a Cp value of 3.95 and a Cpk&#13;
value of 2.28, indicating that the process has a very high capability to meet the&#13;
specified limits. The results demonstrate that the Taguchi method can be used to&#13;
determine an optimum combination of process parameters, while process capability&#13;
analysis can be used to evaluate the stability and capability of the robotic sealant&#13;
application process.</mods:abstract><mods:classification authority="lcc">670 Teknik Industri</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2026-08-06</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGI</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_78765"><mets:rightsMD ID="rights_eprint_78765_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
