Analisis Emosi Dasar pada Film Animasi 3D Ficusia dengan Metode Semiotika Charles Sanders Peirce
No full textConstructing basic emotions in the facial expressions of 3D characters is a complex and time-consuming process, yet it plays a vital role in non-verbal communication by enabling audiences to recognize emotions and understand character traits in animated films. This study aims to address the gap in analyzing how basic emotional signs are represented in animation to support more communicative character design. A descriptive qualitative approach was applied using Charles Sanders Peirce’s semiotic framework of trichotomy, which explores the relationship between sign, object, and interpretant in the facial expressions of the main character. The findings reveal that six basic emotions can be identified through iconic signs, where facial expressions represent specific emotional states, and their meanings are interpreted by the audience. These results demonstrate that Peirce’s semiotics offers an effective approach for analyzing emotional representation in 3D animation and contributes to the development of structured facial expression design strategies. Such strategies not only enhance non-verbal communication, but also strengthen emotional engagement and reinforce character identity in animated storytelling

No full textThe COVID-19 pandemic has not only resulted in significant loss of life but has also caused a critical shortage of Personal Protective Equipment (PPE) for healthcare workers. In response, the global community has leveraged 3D Printing technology to produce face shields. This study aims to analyze and evaluate the conformity of the dimensions of 3D-printed face shields with the head anthropometric measurements of the Indonesian population. Anthropometric data from three head segments (Head Length/D1, Head Breadth/D2, and Face Height/D3) were collected from 377 subjects. Three face shield models (PW1: low grade, PW2: medium grade, PW3: high grade) were manufactured using a 3D Printing machine. The analysis results indicate that the existing designs are not fully compatible with the percentile dimensions of the Indonesian population. Modifications to the frame and visor dimensions are required to better align with Indonesian anthropometric data.

Studi Kasus Kualitas Pengelasan Pada Material A694 F65 Overlay Inconel 625 Claded Menggunakan Metode Kombinasi Gtaw & Smaw
No full textWelding is a method of connecting metal that involves melting a portion of the parent and filler metals until they are liquid enough to fuse. Nowadays, welding is becoming more and more common, particularly in the oil and gas sector. Combining GTAW with SMAW techniques is one of them. Because it can create robust and corrosion-resistant joints, the oil and gas industry frequently uses the combination of GTAW and SMAW welding techniques. The welding procedure on ASTM A694/F65 material covered with Inconel 625 will be covered in this study. While Inconel 625 is resistant to corrosion and stress cracking, A694/F65 steel will offer toughness for applications with low temperature field circumstances. The benefits of the various welding techniques are strategically integrated by this combination of welding procedures. While SMAW delivers great mechanical strength and filling efficiency for the fill to cap weld portions, GTAW will offer superior penetration and surface cleanliness on the root weld. The results of the tests, which included visual inspection, Magnetic Particle Inspection (MPI), and Ultrasonic Testing (UT), demonstrated that no evidence of serious flaws exceeding the acceptance criteria of the cited standards AWS D1.1:2025 for MPI and ASME Section VIII Div. 1 Appendix 12 for UT was discovered. It is anticipated that the study will serve as a guide for the welding procedure on gas and oil pipes.Abstrak
