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.

This study explores the tension between freedom of expression and the enforcement of criminal law in the digital space, using a case study of political memes depicting national figures Prabowo Subianto and Joko Widodo in a satirical context. The case sparked controversy after law enforcement authorities applied morality provisions from Indonesia's Electronic Information and Transactions Law (UU ITE), which many experts consider irrelevant to the substance of the content. Employing a qualitative approach through literature review, the analysis is framed within three theoretical perspectives: Constitutional Democracy Theory, Human Rights Theory, and Criminal Law Theory. The findings reveal that the application of ambiguous provisions in the UU ITE to digital expression has the potential to violate the rule of law, restrict civil liberties, and create a chilling effect on citizens' political participation. Consequently, this study recommends legal reform and the enhancement of digital literacy as strategies to strengthen constitutional democracy in the digital era.

This study aims to isolate and identify microorganisms in the form of bacteria and fungi in tilapia fish waste and to demonstrate the effectiveness of turmeric extract (Curcuma longa Linn.) as an antimicrobial agent. Tilapia fish waste samples were fermented for seven days and then microorganisms were isolated using Nutrient Agar (NA) media for bacteria and Potato Dextrose Agar (PDA) for fungi. Turmeric extract treatment was carried out using the disc diffusion method. The results showed the presence of several species of Gram-positive and Gram-negative bacteria, as well as fungal colonies with dominant characteristics of Aspergillus sp. and Fusarium sp. Turmeric extract with a concentration of 20% showed a significant inhibition zone against the growth of pathogenic bacteria and fungi. The content of secondary metabolites such as alkaloids, tannins, and phenolics in turmeric extract is thought to be the main factor in antimicrobial activity.

Hypertension is one of the cardiovascular disorders characterized by increased blood pressure. One non-pharmacological effort to reduce increased blood pressure can be done through physical exercise. This study was to identify the effect of Isometric Exercise intervention on systolic and diastolic blood pressure in hypertensive patients. The Pre-Experimental Study became the design of this study involving 32 respondents from a population of 104 hypertensive patients through Purposive Sampling. Isometric Exercise intervention was given 4 times in 1 week with a duration of 15 minutes. Blood pressure variables were measured with a tensimeter and the data were analyzed by the Independent T-Test with α 0.05. The results showed a decrease in systolic of 5.875 mmHg (from a mean of 143.125 to 137.125) and diastolic of 3.25 mmHg (from a mean of 91.625 to 88.375). p value = 0.014 (<0.05), meaning that there was a difference in systolic and diastolic blood pressure pre and post test. Isometric exercise can increase stimulation of the sympathetic nervous system so that blood circulation becomes smooth through the mechanism of venous vasodilation causing a decrease in cardiac output and total peripheral resistance, followed by a decrease in blood pressure. Isometric Exercise intervention can be carried out as an effort to manage blood pressure in hypertension patients through a physical exercise approach.
