Abstract

Quality assurance is a critical aspect in the production systems, affecting product quality and safety. Defects and failures of manufactured components will diminish overall product quality, which could vulnerably risk consumer safety. This study focuses on quality assurance analysis of train component manufacturing systems. According to the quality control data, the number of defects recorded was about 10-12, on average, for each wagon produced. The defect mainly occurred while making the underframes, car body, and even the small components. This led to the tardiness of product delivery for 1-2 months. This study aims to analyze non-conformance report data and identify the potential failure modes, potential effects, and root causes. To do so, we integrated systematically FMEA (Failure Mode and Effect Analysis) and FTA (Fault Tree Analysis). First, RPN (Risk Priority Number) score was calculated to determine risk priority. Second, Pareto analysis was performed to select defects that most contributing to overall failures, which were then analyzed using FTA to obtain root causes. The results show that 8 defects exceed the critical RPN score of 209. Materials and personnel are identified as two major contributor failure events from three selected defects. The recommendation for further improvements is provided based on various defect categories to prevent similar defects. The findings demonstrate that the combined use of FMEA and FTA is effective in identifying failures and root causes within complex and long production cycle systems.

Abstract

Human performance is affected by several factors related to work and workplace conditions, including occupational noise.  Noise can affect work and mental performance parameters such as memory, attention, concentration, and reaction time. Reaction time in response to a situation can significantly impact our lives because of its practical implications. Environmental noise invades the learning space and has a negative effect on students' cognitive performance. This study considers the presence of noise factors on students' cognitive performance. High cognitive performance is needed by students, especially in lecture material that requires high memory. Aspects of cognitive ergonomics are included in this study because it examines how people interact with noisy environments. In this study, measuring cognitive performance was carried out by measuring reaction time, number memory performance, and sequence memory performance. Based on the statistical tests in this study, it can be concluded that there is no significant effect of gender on reaction time, number memory, and sequence memory in conditions with noise and without noise. The presence of noise can significantly reduce the performance of sequence memory. Number memory performance decreases in the presence of noise, but not significantly. The reaction time required to respond to the stimulus is longer in the presence of noise, but not significant.

Abstract

Komunikasi merupakan aspek penting dalam kehidupan sehari-hari. Untuk mencapai kinerja yang baik dalam suatu pertandingan dibutuhkan komunikasi antar pemain. Tujuan penelitian ini adalah untuk menganalisis pengaruh komunikasi pemain terhadap durasi pertandingan dan peluang kemenangan pada permainan Mobile Legends. Pada penelitian ini digunakan metode repeated measure, yaitu setiap peserta bermain pada dua kondisi yaitu dengan komunikasi yang relevan dengan permainan dan kondisi tanpa komunikasi. Durasi pertandingan dari awal hingga permainan berakhir dan hasil pertandingan dicatat untuk dianalisis menggunakan metode uji statistik Shapiro Wilk, Wilcoxon Signed Rank Test, dan McNemar Test. Berdasarkan hasil pengolahan data diperoleh bahwa komunikasi yang relevan memiliki dampak yang signifikan dalam mempercepat penyelesaian permainan dengan nilai z sebesar 4,200 dan p-value sebesar 0,0001. Peluang kemenangan juga meningkat secara signifikan pada kondisi dengan komunikasi dengan nilai p-value sebesar 0,041. Hasil penelitian ini menunjukkan bahwa komunikasi berperan penting dalam membangun situational awareness dan pada akhirnya mempengaruhi hasil kemenangan. Oleh karena itu penerapan komunikasi yang relevan penting untuk meningkatkan kinerja permainan berbasis tim.

Abstract

Road safety remains a major public health concern, especially in low and middle-income countries, such as Indonesia; it is closely linked to unsafe driving behavior, along with poor awareness of safety and erroneous perception of risk. Although various training programs are already established, there is limited empirical evidence to identify which configuration produces the greatest safety improvement. This study explicitly aims at analyzing the effects of training characteristics, including the number of sessions, total duration, and training delivery format, on transportation safety outcomes of university students. The research had an experimental pre-post design, with 32 participants. Safety was measured along different dimensions, namely safety attitude, positive safety behaviour, negative safety behaviour, safety violations, and safety knowledge. Safety improvement was defined as the difference in total safety scores post-training and pre-training. Multiple linear regression revealed that total duration, the number of sessions, and training delivery significantly affect the improvement in safety at the 0.05 level. To find a suitable solution, a Genetic Algorithm was used to optimize the solution. The results show that 8 sessions of 1 hour are better than 1 session lasting 8 hours. This is in line with more traditional learning theory that repeated presentations over a given period are more effective for learning and behavioral response. Also, the gap between the 8x1 sessions offered a period over which adjustments could be made. Overall, the results highlight the value of training delivery formats on transportation safety improvements.

Abstract

The advancement of information technology has simplified various tasks, mainly through easier mobile internet access, driven by the rise of social media platforms. Social media serves as both a virtual interaction tool and a promotional medium, including for online shopping applications, which have contributed to the growth of e-commerce in Indonesia. At Telkom University Surabaya, hydroponic and aquaponic activities have started harvesting, requiring a platform to market these products. TUS MART, an online shopping platform developed by Telkom University Surabaya, facilitates consumer access to shop anytime and anywhere. In its prototype stage, TUS MART's usability is being tested using the WebQual Concept. TUS Mart supports environmentally sustainable practices by facilitating the distribution of locally grown products using hydroponic and aquaponic farming methods. Through this approach, TUS Mart helps reduce the carbon footprint of the supply chain and promotes the consumption of healthier, more sustainable products. The study employs the Importance Performance Analysis (IPA) and Potential Gain in Customer Value (PGCV) methods to assess and prioritize improvements. The PGCV index identifies key attributes for service quality enhancement. Prioritized improvements include variable E4 in the Entertainment dimension (minimizing excessive ads), E3 in the Entertainment dimension (attractive text forms), W7 in the Web Appearance dimension (engaging content composition), and W6 in the Web Appearance dimension (attention-grabbing colors). These findings provide actionable insights for optimizing TUS MART's service quality.
