Abstract

Crowded speech or Overlapping speech, occurs when multiple individuals speak simultaneously, which is a common occurrence in real-life scenarios such as telephone conversations, meetings, and debates. The critical task in these situations is to identify all the speakers rather than just one. Overlapping speech identification is a significant research domain with applications in human-machine interaction, criminal detection in airports, trains, and public spaces. Our work examines crowd speech identification from four perspectives, including the most commonly used datasets, the most effective features for crowed speaker identification, and the best methodologies employed, and the highest results gained. This study proposes a comprehensive survey of research on crowd speech identification, covering the period from 2016 to present. The survey includes ninety research papers, fifty of which, are empirical studies. Initially, statistical methods were predominant, but the current trend leans towards artificial intelligence, particularly deep learning, which has demonstrated considerable efficacy in this field.

Abstract

Even though mobile tourism analysis is developing, there is still a lack of literature regarding its formation patterns which makes the picture of its evolution incomplete. The evaluation in this study was carried out in general by emphasizing the evolution of exploratory analysis on the theme of "mobile tourism". This article aims to determine the increasing development of mobile tourism in terms of the number of publications, journals, authors, and the most relevant citations. Then analyze the itinerant tourism distribution map based on grouping, with merging, joint citation, collaboration network analysis, and joint word assessment, and interpret the conceptual structure of the country's co-occurrence and collaboration network regarding its visual representation. The method used is a descriptive approach through bibliometric analysis. An in-depth search of the Scopus database and RStudio software was conducted, screening, analyzing, and interpreting 752 relevant articles from 2014 to 2023. The findings show that an increase in the development of mobile tourism is identified from an increase in the number of publications, the most relevant journals, and authors, as well as the increasingly diverse origins of the authors even though the number of annual average citations has decreased slightly. Recommended six themes in mobile tourism studies, namely Tourism, Technology Acceptance Models (TAM), Mobile Applications, Recommendation Systems, Loyalty, and Cultural Tourism, and produced Technology Acceptance Models and Tourism as important studies with great prospects in the future.

Abstract

Many factories have set up a safety management system (PSM), and there is an increasing rate of safety management systems. This is increasingly in line with the development of industrial plants. External and internal inspection of security management processes are the core of Process Safety Management (PSM) and are an essential opportunity to improve operational solutions. The problems of security inspection arise due to unclear and unplanned inspection issues, resulting in unsystematic monitoring of factual information and opinions and loss of opportunities to achieve goals throughout the organization. This research aims to improve the inspection process by using computer software technology in auditing.   After improving the process according to the Lean Process Management (ECRS) concept to reduce waste, the workflow was reduced by 40.74%, and 60% efficiency was increased. In addition, the assessment results from a sample of PSM auditors showed 93.4% satisfaction as the most appropriate. Therefore, this study demonstrated the potential and benefits of implementing the Process Safety Management System (PSM) audit program and applying Lean theory to improve auditing, which can be used as an essential reference for future research and program development.

Abstract

This research explores the implementation of a cutting-edge Software Defined Radio (SDR) framework to transmit multimedia files that can be assumed to be medical data in smart ambulances. The system utilizes multi-carrier Orthogonal Frequency-Division Multiplexing (OFDM) across V2V and V2I channels. The research is based on the notion that adaptive real-time communication is essential for the uninterrupted supply of key patient data to medical facilities and vehicles in transit, in order to address the problems posed by high mobility and dynamic environmental conditions. A comprehensive SDR system has been constructed and assessed in comparison to conventional communication mechanisms, demonstrating notable advancements in data accuracy and uninterrupted transmission. Our system successfully established stable connections in V2I channels, even in the presence of environmental obstacles. It maintained average power levels of approximately 32.074 dBm and a Peak-to-Average Power Ratio (PAPR) of 1.037 dB. These results indicate a constant signal envelope that promotes optimal signal transmission with excellent fidelity. In V2V scenarios, we successfully maintained data integrity with a low Peak-to-Average Power Ratio (PAPR) of 3.316 dB, even while vehicles were moving at a speed of 20 km/h. Additionally, we secured a high likelihood (94.5%) that the signal power remained close to the average, showing the robustness of our system against Doppler effects and signal dispersion. Text transmissions experienced errors when subjected to a Doppler shift of 20 km/h, which impacted the decoding of the received text. Similarly, image transmissions revealed limitations in bandwidth, as a transmitted image of 3640 KB was received with a degraded 4 KB. This emphasizes the importance of implementing effective error handling and recovery mechanisms. The results illustrate the efficacy of the suggested system in maintaining a high Quality of Service (QoS), offering proof of the effectiveness of contemporary wireless communication technologies in improving emergency medical services and setting new standards in smart ambulance capabilities.

Abstract

 As digital technology accelerates at an unprecedented pace, educational institutions and businesses are looking for more efficient and accurate ways to record attendance. Traditional attendance methods, such as manual signing or manual data entry, can face several challenges, including human error, inaccuracy, and time consumption, ultimately leading to decreased efficiency and productivity. With the increasing demand for smarter and more efficient solutions, it has become imperative to explore new technologies that can improve this vital process. The main problem is that traditional attendance systems are unable to keep up with the speed, accuracy, and security demands of the modern era. These systems are often prone to errors, which can result in incorrect or inaccurate attendance, and the attendance process can be time-consuming, especially in large groups, reducing time allocated for educational or productive activities. This study aims to develop an automated attendance system using real-time face detection technology, with the aim of improving efficiency, accuracy, and security compared to traditional attendance methods. Haar Cascades technology was used to recognize and classify faces, with attendance data stored in a MySQL database managed via SQL. The results of the study showed an accuracy rate of up to 97.44% in detecting faces and recording attendance under different conditions. It is proposed to enhance this system in the future by integrating anti-impersonation and mask detection technologies and using deep learning principles to increase security and effectiveness in different scenarios.

Abstract

This study aims to optimize tensile strength in Stereolithography (SLA) 3D printing by investigating the effects of print orientation and layer orientation on mechanical properties. Employing a multilevel factorial design, we systematically analyzed various print andlayer orientations using both experimental and computational methods. The experimental component, performed with an Instron 5566 machine, identified a print orientation of 22.5 degrees and side orientations as optimal, achieving a tensile strength of 72.01 MPa. Computational simulations using ANSYS software supported these findings, showing a close correlation between experimental and simulated results. This research not only advances theoretical understanding of SLA 3D printing processes but also offers practical insights for optimizing tensile strength in manufacturing applications. By integrating experimental and finite element analysis (FEA) results, which predicted a maximum stress of 71.97 MPa under a 686 N load, the study contributes valuable knowledge for enhancing additive manufacturing practices and informs future research on parameter optimization

Abstract

This study explores the development of a novel side core design with an integrated cooling system for the low-pressure die casting (LPDC) of A356 aluminum alloy wheel rims in Indonesia. The objective is to reduce cycle time and minimize casting defects. The methodology involves 3D modeling using SolidWorks and simulations performed with MAGMAsoft to evaluate filling and solidification behavior, air pressure, and air entrapment. Notably, this is the first application of a cooling system in Side cores within the Indonesian automotive industry, motivated by the need to improve production efficiency and product quality, as current manufacturing processes suffer from long cycle times and high defect rates. Simulation results show a significant reduction in cycle time by 72 seconds, improving both efficiency and product quality. This study demonstrates the effectiveness of integrating cooling systems into side cores to enhance the LPDC process.

Abstract

This study investigates the effectiveness of mango peel extract as a corrosion inhibitor for ASTM A53 steel, which is widely used in the oil and gas industry. The research aims to evaluate how different concentrations of mango peel extract can mitigate corrosion in seawater from Pangandaran, thereby extending the lifespan of steel components in marine environments. Corrosion tests were conducted through immersion experiments over durations of 1, 4, 9, 16, and 25 days with mango peel extract concentrations of 0 ppm, 20 ppm, 40 ppm, 60 ppm, and 80 ppm. Analytical methods including X-ray diffraction (XRD), Optical Microscopy (OM), energy dispersive spectroscopy (EDS), and scanning electron microscopy (SEM) were used to examine the steel's surface morphology and chemical composition. The results demonstrate that mango peel extract significantly reduces the corrosion rate of ASTM A53 steel, with the highest efficiency achieved at 40 ppm (58.15%) and a notable reduction at 60 ppm (56.4%). The inhibition is attributed to chemical absorption, which lowers the steel's corrosion potential. These findings suggest that mango peel extract is an effective, eco-friendly corrosion inhibitor, offering practical and theoretical benefits for corrosion management. This research supports the use of bio-based inhibitors and may inform future industrial corrosion protection strategies.

Abstract

This paper aims to apply the halal value chain to Tanah Liek Batik textiles to become halal batik products, using a framework designed to analyze the halal value chain. The method used in dealing with this problem is to apply HCCP (Halal Critical Control Point) to the company's activity value chain to become a halal value chain. The initial data used is a flow diagram of the production process of four types of Tanah Liek Batik products: Tanah Liek dyed batik, chemically dyed batik, stamped batik with soil-like dye, and chemically dyed batik. Based on the results of the identification of haram materials in each process in the activity, the Halal Control Point (HCP) is obtained. The application of HCCP to the Tanah Liek Batik value chain has 13 critical points of haram products, which come from the process, facilities, and tools and materials used during the production process. This study also produces a Halal Value Chain framework in the Textile Industry. Applying this framework in the textile industry is expected to increase the number of halal-certified textile industries.
