Abstract

Dirgantara Indonesia (PTDI) is the single source producer of the NC212i Aircraft. Almost every Aircraft is delivered to the customer over the deadline date. The existence of waste is believed to be one of causing the late delivery. Based on observations of the 117th NC212i Aircraft assembly line, which is precisely at the fuselage assembly in the paneling group, six wastes are identified: waiting, transportation, overprocessing, inventory, and motion. Waste of overproduction does not occur because PTDI applies MTO (Make to Order) system. These 6 wastes are then processed using Waste Assessment Model (WAM). The ranking result is: first place is 25% for defects, second place is 23% for waiting, third place is 17% for motion, fourth place is 15% for inventory, fifth place is 13% for transportation, sixth place is 8% for overprocessing, and seventh place is 0% for overproduction. Three critical wastes based Pareto principle can be minimized, so the delay of aircraft delivery can be reduced.

Abstract

Design thinking is a human-centered problem-solving methodology focusing on innovative solutions. Design thinking can be used to improve the user experience of a website. Design thinking consists of empathize, define, ideate, prototype, and test phase. Based on preliminary observation, the current UNS Graduation Website demonstrates significant usability issues that interrupt the user experience. The lack of error prevention and informative feedback leads to repeated mistakes and user frustration. Additionally, visual and functional inconsistencies further reduce usability. These issues were confirmed through the System Usability Scale (SUS), which yielded a low score, indicating a difficult and unpleasant user experience. To address these issues, this study applies the design thinking methodology to re-design the UNS Graduation Website with the aim of improving its usability and enhancing user experience. The prototype is tested by 20 users using usability testing tools named Maze and System Usability Scale (SUS). The result based on Maze testing, the prototype got a success rate percentage of 100% and a usability score of 85 for the UNS Graduation Website. The usability score tested by SUS also increased from 43,25 to 82. This affirms the successful outcome of the re-design in improving the user experience and increasing the usability of the UNS Graduation Website.

Abstract

The guitar industry is in Mancasan, Sukoharjo regency is a small medium enterprises which carried out finishing process to produce acoustic guitars. All of the process are done manually without any machine. There is one process called fret wire installation where the operator is in a static work posture for an extended period of time to hold the work piece. Nordic Body Map (NBM) assessment showed that almost all assessed workers have pain in hip and right upper arm. There is indication of Musculoskeletal Disorders (MSDS) risk in left upper arm, back, and waist of workers who conduct fret wires installation process. This indication is confirmed using REBA. REBA Score for fret wiring operator is 10, it indicates that the investigation and modification was needed as soon as possible. This arises to a problem called workers MSDS due to awkward posture. This research aims to design an ergonomic working table to reduce the risk of musculoskeletal disorder for fret wire installation operators. REBA was used to evaluate working posture to find the specific problem. In addition, NIDA product development process and anthropometry concept were also implemented to develop working table based on the problem previously found. The result is the proposed working table which specifications are has adjustable system on the leg of the table, features a lock to hold the guitar head, a support with a pad for the neck and body of the guitar, a work tool area and a half-coil fret wire arrangement, and a curved table base so that the operator is in a comfortable position and is close to the work piece.

Abstract

Archery performance as a precision sport is determined by a complex interaction between psychological and physiological factors. Concentration, as a crucial factor, can be objectively measured through electroencephalography (EEG) by detecting beta waves. However, current coaching practices disproportionately emphasize physical aspects while systematically ignoring concentration as a crucial psychological factor. Generally, studies assess performance through aggregate scores without distinguishing between two fundamental dimensions: accuracy and precision. This study aims to analyze the relationship between concentration levels measured through beta band power activity using EEG and shooting performance in archery athletes, focusing on shooting accuracy and shooting precision. This study offers empirical contributions about the relationship between concentration and two dimensions of shooting performance, develops a methodological validation that integrates EEG monitoring with smart bow technology, and establishes a practical foundation for developing concentration-based training programs in archery. The research subjects consisted of 12 novice archery athletes. EEG data were acquired with electrodes positioned at AF7 and AF8, monitoring beta band power during shot execution. Pearson’s correlation was used to analyze the relationship. The results showed a shot accuracy with an average score of 131.17, while precision showed an average SRD of 11.00 cm. Beta band power had a mean of 39.18 µV². Correlation analysis revealed a non-significant positive relationship between beta power and accuracy (r = 0.145, p = 0.652), as well as a non-significant negative relationship with precision (r = -0.327, p = 0.300). Study findings show that beta wave activity alone does not serve as a significant predictor of shooting performance in novice archers. However, the differential correlation pattern (positive for accuracy, negative for precision) confirms that these two dimensions are influenced by different psychophysiological mechanisms.

Abstract

Mosque visitors often struggle with poorly designed wayfinding signs. Small fonts, unappealing color combinations, illogical placement, and dazzling materials contribute to this frustration. Common complaints involve signs for toilets, ablution areas, prayer halls, and holy boundaries. This study aimed to improve signage legibility by applying ergonomic principles. The visual display cognitive ergonomics approach was chosen, with a focus on human-system interaction and acknowledgment of human limitations. An experimental design was used to evaluate the effects of font size, typeface, and color combinations on legibility. Additionally, symbol comprehension tests and assessments of familiarity, compatibility, and standardization were conducted to inform the design of effective symbol signage. The experimental data were analyzed using the Friedman test. Spearman’s rank correlation test was used to assess the relationships among the three ergonomic factors: familiarity, compatibility, and standardization. Data analysis revealed that only font size significantly impacted legibility. However, a positive correlation was found between ergonomic factors and participant understanding of the signage symbols. This suggests that these factors collectively affect overall legibility. After introducing the newly designed signage, the study successfully increased sign legibility. Future research can explore additional factors that influence legibility to develop more comprehensive guidelines for mosque signage design.

Abstract

Kemuning Sky Hills is a natural tourist attraction in Karanganyar Regency that offers various extreme rides, including a glass bridge, a sky swing, a flying chair, and a flying bicycle. Although it attracts tourists, the safety risks associated with these rides have not been optimally managed. This study aims to assess safety risks using the Hazard Identification, Risk Assessment, and Determination of Control (HIRADC) and provide a deeper understanding of the importance of safety risk analysis in extreme tourism destinations. The risk assessment is based on the Australian Standard HB 205-2004 reference. Data were collected through direct observation, interviews with officers and visitors, and field documentation. The results showed that several potential hazards fall into the High Risk to Extreme Risk categories. There are 10 risks in the High Risk category and 4 risks in the Extreme Risk category. The most extreme risks identified include overloading due to visitor density, gaps in the fence on the Glass Bridge, broken ropes on the Sky Swing, and the threat of landslides in the tourist area. Proposed controls include installing safety nets, rope guides, and warning signs, establishing a structured maintenance schedule, and providing education. This study concludes that safety management at Kemuning Sky Hills should be strengthened by implementing an integrated, structured safety management system that includes standardized operational procedures, routine risk assessments, clear emergency response mechanisms, and continuous staff training to ensure a consistently safe and sustainable tourist environment.
