Abstract

Variations in task performance under different cognitive demands are often interpreted as indicating mental workload. Prior research has identified a link between personality and task performance. This study investigates whether personality traits influence performance under varying levels of mental workload in working memory tasks. Personality traits were assessed using the Eysenck Personality Inventory. Participants completed n-back tasks at three levels of difficulty to induce different levels of mental workload. The findings reveal significant differences in response times between extroverts and introverts across all task difficulties (p < 0.05), with introverts responding more quickly. A significant difference between neurotic and stable individuals emerged only at the medium difficulty level (p < 0.05), with stable individuals performing faster. Additionally, response times varied significantly across personality quadrants, with introvert-neurotic individuals showing faster responses at both low and high difficulty levels.

Abstract

This study aims to identify the environmental impacts arising from the electricity generation process at PT. X and to determine alternative mitigation scenarios that can be applied to reduce these environmental impacts. Using the Life Cycle Assessment (LCA) approach, the study successfully identified the Cooling Tower as the main hotspot in the generation process, with emissions such as CO?, H?S, NH?, and NO? contributing to global warming potential, acidification potential, eutrophication potential, and human toxicity. Based on the analysis using Analytical Hierarchy Process (AHP), the most effective mitigation alternative to reduce environmental impacts is the use of High Performance Lubricant (HPL) for the Fan Cooling Tower (FCT) system. The use of HPL received the highest priority, with a weight of 46.9% of the total decision, as it can reduce friction and heat, leading to improved energy efficiency and reduced motor power consumption. This research contributes to the development of mitigation strategies that can be applied to achieve a more sustainable, efficient, and environmentally friendly geothermal power plant, while also supporting Indonesia's energy transition.

Abstract

Service quality in aviation fuel supply operations is critical due to its direct impact on flight punctuality, safety, and overall airport performance. This study aims to systematically identify service quality gaps, prioritize customer requirements, and determine actionable technical responses to improve refueling services at DPPU Juanda. An integrated framework combining SERVQUAL, Importance Performance Analysis (IPA), Focus Group Discussion (FGD), Best Worst Method (BWM), and Quality Function Deployment (QFD) is employed to translate customer expectations into prioritized technical initiatives. The results indicate that schedule integration with stakeholders, real-time monitoring of refueling operations, and strengthening apron audit systems emerge as the most critical technical priorities for service quality improvement. The proposed framework provides a structured decision-support approach that supports managerial decision-making and offers practical guidance for enhancing service reliability in aviation fuel supply operations.

Abstract

The development of Artificial Intelligence (AI) technology provides significant opportunities for the manufacturing industry to improve the efficiency and accuracy of quality inspection processes. The implementation of AI in quality inspection is expected to reduce human error and accelerate decision-making. However, the successful adoption of this technology depends largely on user acceptance and intention to use it within the work environment. Many digital transformation initiatives fail to achieve optimal outcomes due to employees’ limited perceptions of technological benefits and ease of use. Therefore, this research is important for understanding the factors influencing user acceptance of AI-based quality inspection systems, enabling companies to develop more effective implementation strategies. This study applied the Technology Acceptance Model (TAM) by incorporating the variables of perceived usefulness (PU), perceived ease of use (PEU), perceived enjoyment (PE), perceived cyber risk (PCR), perceived innovativeness in IT (PIIT), self-efficacy (SE), and behavioral intention (BI). The research employed a quantitative approach through questionnaire distribution to employees at PT XYZ who were directly involved in quality inspection activities. The results of the study using the PLS-SEM method showed that the perceived usefulness (PU) variable had the strongest significant effect on behavioral intention (BI). Therefore, strategies to improve technology acceptance should prioritize variables with substantial impacts, particularly by providing training and enhancing employee understanding of the benefits of AI in supporting work performance.

Abstract

Perubahan iklim mendorong industri otomotif untuk mengembangkan kendaraan rendah emisi melalui penerapan teknologi dan sistem manufaktur yang lebih berkelanjutan. Salah satu upaya tersebut diwujudkan melalui Project 1*5D, yaitu proyek perakitan kendaraan rendah emisi dengan skema Semi Knocked Down (SKD) dan target Tingkat Komponen Dalam Negeri (TKDN) sebesar 40%. Dalam implementasinya, pemilihan lokasi assembly line dan final test menjadi permasalahan pengambilan keputusan multikriteria yang harus mempertimbangkan berbagai aspek teknis dan operasional secara bersamaan. Penelitian ini bertujuan menentukan alternatif lokasi assembly line dan final test terbaik pada Project 1*5D menggunakan pendekatan Multi-Criteria Decision Making (MCDM) melalui integrasi metode Analytical Hierarchy Process (AHP) dan Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE). Metode AHP digunakan untuk menentukan bobot kepentingan setiap kriteria berdasarkan penilaian para ahli, sedangkan metode PROMETHEE digunakan untuk mengevaluasi dan memeringkat alternatif berdasarkan bobot tersebut. Kriteria yang digunakan meliputi Driving Range, Vehicle Quality, MP Management, Cost, Equipment/Layout Modification, Part Handling, dan Space Availability. Data penelitian diperoleh melalui studi literatur, observasi lapangan, dan penyebaran kuesioner kepada responden ahli. Analisis dilakukan melalui pembobotan AHP, pemeringkatan menggunakan PROMETHEE II, serta analisis sensitivitas untuk menguji kestabilan hasil. Hasil penelitian menunjukkan bahwa Vehicle Quality merupakan kriteria dengan bobot tertinggi sebesar 0,278, diikuti oleh MP Management sebesar 0,205 dan Cost sebesar 0,176. Berdasarkan hasil analisis PROMETHEE II, Option 2B (Pilot Line Log#2) memperoleh nilai net flow tertinggi sebesar 0,318, sehingga dipilih sebagai alternatif terbaik. Hasil analisis sensitivitas menunjukkan bahwa perubahan bobot kriteria Vehicle Quality hingga ±15% tidak mengubah urutan peringkat alternatif, yang mengindikasikan bahwa model pengambilan keputusan yang diusulkan memiliki tingkat kestabilan yang baik. Model yang dihasilkan dapat digunakan sebagai dasar pengambilan keputusan dalam pemilihan lokasi proyek manufaktur otomotif yang melibatkan berbagai kriteria secara sistematis dan objektif.
