The welding process is a crucial element in the fabrication and manufacturing industries, serving to join two or more components into a single unit. The quality of the weld is very important, but defects such as undercut, underfill, and spatter are often still found. This study aims to analyse welding defects caused by voltage variations and differences in welding wire on T-joint fillet welds using the Gas Metal Arc Welding (GMAW) method on 8 mm thick plates. The voltage variations used were 20.6 V, 23.7 V, and 27.9 V, with welding wires EN ISO 14341-A: G 42 4 M21 3Sil and EN ISO 14341-A: G 46 4 M21 Z 3Ni1Cu. The research method used visual inspection and penetrant testing to identify types of welding defects. The research results showed four types of welding defects from visual inspection: spatter, undercut, weld deposit thickness, and excessive throat thickness, and two from penetrant testing: undercut and end creater pipe. Based on the two tests conducted in this study, it can be concluded that the optimal welding results were achieved at a voltage variation of 23.7 V using the EN ISO 14341-A: G 46 4 M21 Z 3Ni1Cu, as it had the fewest welding defects. The worst welding results were obtained at a voltage variation of 20.6 V using both types of welding wire, as this welding process resulted in numerous welding defects in both visual and penetrant testing. This study provides insights that proper welding parameter settings significantly influence the quality of the welded joint.

Galangal (Kaempferia galanga L.) is a herbal plant known to have anti-inflammatory, antibacterial, and antioxidant activities. The use of galangal extract in topical pharmaceutical preparations such as ointments, gels, and creams requires attention to the physical stability of the preparation to ensure the effectiveness and safety of the product. This study aims to examine the physical stability of various forms of galangal extract-based preparations through literature studies from three relevant journals. The method used is a descriptive literature study by analyzing the results of physical stability tests (organoleptic, pH, homogeneity, spreadability, adhesion, and viscosity) of ointments, gels, and creams. The results of the study showed that the gel form with a carbopol base provided the best overall physical stability, followed by an ointment with a water-washed base. Meanwhile, sunscreen cream made from galangal and seaweed showed quite good stability, although its spreadability and adhesion still need to be improved. This study provides an overview that the form and composition of the preparation greatly affect the physical stability of galangal extract, as well as the importance of choosing the right base in the formulation.
