The reliability and safety of aviation fuel distribution systems depend heavily on effective pipeline inspection methods capable of detecting internal coating degradation and structural defects. Conventional in-line inspection approaches often involve high operational costs, complex deployment requirements, and limited suitability for airport apron environments, creating a research gap in developing efficient and intelligent inspection solutions. This study aims to develop an AI-driven pipeline inspection framework for avtur systems by integrating robotic visual inspection, computer vision, and data mining techniques to support automated defect identification and maintenance decision-making. The research focuses on transforming robotic camera observations into structured image datasets and applying intelligent classification methods to evaluate internal pipeline conditions. A computer vision-based approach was employed involving image preprocessing, feature extraction, defect segmentation, and supervised machine learning classification to categorize pipeline conditions into operational decision classes, including Fit for Service, Conditional Service, and Not Fit for Service. The results demonstrate that the proposed framework achieves high classification accuracy while reducing inspection cost and decision latency compared with conventional inspection methods. The findings indicate that combining robotic sensing with AI-based image analytics provides a reliable and practical approach for safety-critical pipeline monitoring. This study contributes to intelligent industrial inspection and predictive maintenance research by providing an AI-enabled solution for aviation fuel infrastructure management. Future research should explore deep learning-based defect detection, edge AI deployment, real-time monitoring systems, and explainable AI techniques to improve scalability, transparency, and operational reliability.
Small-scale fisheries in tropical coastal regions lose substantial catches to inadequate cold storage infrastructure, and no structured decision framework addresses this gap. The trade-offs among economic, technological, and environmental criteria resist intuition. Using AHP-TOPSIS, we evaluated four cold storage design alternatives against seven criteria grouped under three pillars (Economics, Technology, Environment). Pairwise judgments remained consistent, with the highest sub-level Consistency Ratio reaching 0.008 (Technology pillar). The prefabricated polyurethane panel with rooftop cooling (A2) ranked first (CC = 0.6266), followed by conventional masonry (A1, 0.5662), modular steel with IoT monitoring (A4, 0.5265), and insulated concrete with solar-hybrid cooling (A3, 0.3330). Sensitivity analysis showed A2 winning 91.4% of scenarios; A4 outranked A2 when either the IoT-readiness weight (C3) exceeded 0.21 or the investment-cost weight (C1) fell below 0.20. Despite the lowest-carbon profile, A3 ranked last under cost-dominant weights, a structural green penalty against the most sustainable design. Cooperative ownership can move the optimum toward IoT-enabled A4 by pooling capital that individual operators cannot mobilize alone.
Penelitian ini bertujuan untuk menganalisis teknik komunikasi inklusif dalam interaksi antara barista teman Tuli dan pelanggan untuk membangun pemahaman di Coffee Sunyi Jakarta. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan Communication Accommodation Theory (CAT), khususnya konsep convergence, sebagai landasan analisis. Data diperoleh melalui wawancara terhadap empat informan yang terdiri atas dua barista teman Tuli dan dua pelanggan, observasi, serta dokumentasi selama periode pengumpulan data pada 24–27 September 2026. Hasil penelitian menunjukkan bahwa komunikasi antara barista teman Tuli dan pelanggan menggunakan berbagai bentuk komunikasi, yaitu bahasa isyarat, gestur, ekspresi wajah, tulisan, media digital, dan bantuan visual. Ketika pelanggan mengalami kesulitan memahami bahasa isyarat, barista melakukan penyesuaian dengan menggunakan tulisan melalui kertas atau media digital serta gestur dan bantuan visual. Penyesuaian juga dilakukan oleh pelanggan melalui penggunaan media tulisan dan upaya mempelajari bahasa isyarat yang digunakan barista. Penyesuaian komunikasi tersebut turut mendukung terciptanya kesetaraan dalam interaksi antara barista teman Tuli dan pelanggan, meningkatkan pemahaman pelanggan terhadap bahasa isyarat, serta mengurangi kecanggungan dalam proses komunikasi dan pelayanan. Pengalaman berkunjung lebih dari satu kali pada informan pelanggan tertentu juga menunjukkan bahwa pengalaman interaksi dapat membantu mereka menjadi lebih familiar dengan bentuk komunikasi yang digunakan, tetapi temuan tersebut tidak dapat digeneralisasikan kepada seluruh pelanggan. Penelitian ini memiliki keterbatasan pada pengamatan langsung yang dilakukan dalam satu hari sehingga belum menggambarkan seluruh variasi interaksi pelanggan. Penelitian selanjutnya disarankan membandingkan pengalaman pelanggan baru dengan pelanggan yang telah sering berkunjung untuk memahami proses adaptasi dan akomodasi komunikasi secara lebih mendalam.
Abstract—Using a non-invasive Optical Coherence Tomography (OCT) system combined with air-pressure indentation, the Effective Young’s Modulus was measured in healthy participants to evaluate tissue stiffness. The intervention compared two pulse configurations at 1 Hz: a 20% duty cycle and an 80% duty cycle for 6 min. Experimental results showed that the 80% duty cycle led to significantly higher stiffness in the plateau regime (E2) and densification regime (E3) compared to the 20% duty cycle. These findings suggest that acute Low-Level Laser Therapy (LLLT) induces immediate structural changes in healthy plantar tissue, demonstrating that a higher energy delivery alters subsurface layer tension. This OCT-based methodology proved highly effective for precise, non-contact biomechanical mapping, providing a crucial quantitative baseline for future clinical research involving compromised or wounded tissues.
Artikel ini menganalisis pembentukan daerah asimilasi percontohan dengan perspektif Second Generation Crime Prevention Through Environmental Design (CPTED) di Kebayoran Lama dan Kebayoran Baru. Penelitian memakai mixed methods dengan explanatory sequential design. Data kuantitatif berasal dari 143 responden masyarakat, sedangkan data kualitatif berasal dari enam Warga Binaan Pemasyarakatan (WBP) dan satu Pembimbing Kemasyarakatan. Survei menguji kohesi sosial, budaya komunitas, konektivitas, kapasitas ambang, dan persepsi terhadap asimilasi. Keempat dimensi CPTED berhubungan dengan persepsi asimilasi (r = 0,398-0,668; p < 0,001). Regresi berganda signifikan (F = 55,066; p < 0,001; adjusted R² = 0,604), dengan koefisien terbesar pada konektivitas (B = 0,480). Perbedaan antarkecamatan muncul pada budaya komunitas, konektivitas, dan persepsi asimilasi. Pengkodean ATLAS.ti menghasilkan 40% sentimen negatif, 35% positif, dan 25% netral; stigma serta akses ruang publik yang tidak konsisten berulang dalam wawancara. Hasil tersebut menjadi dasar rancangan daerah percontohan yang menggabungkan kesiapan komunitas, ruang publik yang dapat diakses, partisipasi WBP dalam pengawasan Bapas, dan evaluasi berkala.
