Abstract

Search and Rescue (SAR) officers work in high-risk conditions that require physical and mental resilience. Prolonged stress can affect the performance and success of SAR operations. This study evaluates the effectiveness of Electroencephalography (EEG) coherence analysis as a method for monitoring stress in SAR personnel. Using the OpenBCI EEG device and electrodes in the F3 and F4 areas, the brain activity of SAR personnel was recorded in two conditions, office activity (baseline) and rescue operations (SAR condition). The data collection for this research involved the same participants in both baseline and SAR operation conditions, resulting in 30 raw EEG data for further analysis. Data collection on operational conditions was carried out while the rescue officers conducted a search and rescue operation for a capsized boat in the Bengawan Solo River, Ngadirejo Village, Tuban Regency. Data analyzed based on coherence values obtained through the Power Spectral Density (PSD) features of alpha, beta, and gamma sub-band to detect changes related to stress levels. The results showed an increase in coherence in the alpha sub-band by 85.5%, beta sub-band by 92.9%, and gamma sub-band by up to 94.9% during moderate stress conditions, reflecting increased attention, alertness, and intensive information processing required in emergency situations. These findings indicate that EEG coherence analysis can be an effective tool for monitoring stress in SAR personnel in real-time.

Abstract

This study examines how traditional forms of religious authority are undergoing change alongside the increasing use of digital media in religious practices. Using a digital ethnographic method, the research was conducted on an online meditation community guided by Samanera Abhisarano from December 2021 to July 2022. Participant observation was carried out online through a WhatsApp group and Zoom meditation sessions, as well as on-site at Vihara Dhammadipa Arama, where Samanera Abhisarano leads meditation remotely. In-depth interviews were conducted with the spiritual guide and five community members. Referring to Campbell’s (2007) framework of religious authority, the study reveals that traditional forms of authority tend to be preserved, although in practice they undergo several adaptations. These findings support previous studies suggesting that, in certain contexts, the adoption of digital media does not weaken traditional religious authority, but rather reinforces it, particularly when it is managed by religious leaders. This research contributes to the ongoing discourse on media and religion from the perspective of a Buddhist community in Indonesia, where the majority of the population is Muslim.

Abstract

This research aims to examine scientific articles that are relevant and related to the implementation of diagnostic assessments. The research method used in writing this article is a literature review. The literature review was obtained from articles published in the last 5 years, namely from 2019 to 2023. The literature search was focused on the keyword "Diagnostic Assessment" so that a total of 29 articles were obtained, for research at the secondary school level, which were accessed via the Publish or Peerish application. However, after going through the screening stage there were 17 articles in the open access category and relevant to the topic of discussion. Based on the results of the literature review analysis, there are doubts from teachers to carry out diagnostic assessments because teachers have not received a lack of socialization regarding the Implementation of the Independent Curriculum (IKM), so that training and guidance for teachers needs to be carried out. Apart from that, in the implementation of diagnostic assessments, it was found that (1) diagnostic assessments can be implemented in the independent curriculum at primary and secondary school levels, (2) implementation of diagnostic assessments can also help students overcome learning problems with various learning styles. (3) Diagnostic assessments can evaluate students' strengths and weaknesses (4) while from the educator/teacher side they can be used to plan learning strategies. Apart from that, there are also diagnostic assessment tools that teachers can use, such as the Fout-tier Test Diagnostic and Google Form.

Abstract

Hazard Identification Risk Assessment Risk Control (HIRARC) is the process of identifying hazards that can occur in routine or non-routine activities in a company or workplace, then carrying out a risk assessment of these hazards.And from the risk assessment, the hazards in the welding workshop that have a moderate risk and are interesting for researchers to innovate are from sources of danger caused by smoke resulting from welding activities, causing workers to experience respiratory problems and eye irritation. Researchers created a smoke filtration device generated from welding with a system where the welding smoke is channeled into the KOH solution to reduce the number of air particles and reduce the levels of toxic substances in the welding smoke, then to keep the KOH solution always clean, a circulation system was created through the carbon to removes dirt and keeps the solution water from being dirty and colorless.Once all the tools are ready, measurements can be made to measure several chemical elements in the welding smoke from the point before it enters the filter and after going through the filtration process. Among the elements measured are Carbon Dioxide (CO 2), Carbon Monoxide (CO), Particulate PM 2.5 (2.5 Microns), and Particulate PM 10 (10 Microns). Based on research and data testing carried out using the Anova Test and Fisher Pairwise Comparisons, it can be concluded that to produce the best and cleanest air results, the composition is K4 C1 or KOH 10% with Cabon Active 2-3 Mesh. Because if activated carbon with a mesh size larger than 2-3 mesh will affect the quality of the KOH solution because the granules are too small and contaminate the KOH solution. And the higher the KOH solution level, the more effective it is at reducing the dangerous elements in welding fumes.

Abstract

Wireless Sensor Network (WSN) is a collection of sensors communicating at close range by forming a wireless-based network (wireless). Since 2015 research related to the use of WSN in various health, agriculture, security industry, and other fields has continued to grow. One interesting research case is the use of WSN for the monitoring process by collecting data using sensors placed and distributed in locations based on a wireless system. Sensors with low power, multifunction, supported by a combination of wireless network, microcontroller, memory, operating system, radio communication, and energy source in the form of an integrated battery enable a monitoring process of the monitoring area to run properly. The implementation of the wireless sensor network includes five main parts, namely sender, receiver, wireless transmission media, data/information, network architecture/configuration, and network management. Network management itself includes network configuration management, network performance management, network failure management, network security management, and network financing management. The main obstacles in implementing a wireless sensor network include three things: an effective and efficient data sending/receiving process, limited and easily depleted sensor energy/power, network security, and data security that is vulnerable to eavesdropping and destruction. This paper presents a taxonomy related to the constraints in implementing Wireless Sensor Networks. This paper also presents solutions from existing studies related to the constraints of implementing the WSN. Furthermore, from the results of the taxonomy mapping of these constraints, new gaps were identified related to developing existing research to produce better solutions.

Abstract

Limbah pohon pisang yang meliputi batang pohon memiliki potensi pemanfaatan yang beragam, diantaranya dapat digunakan menjadi struktur material pada bahan bangunan salah satu diantaranya adalah cladding. Pada penelitian ini dibuat komposit menggunakan serat alam (batang pisang) menggunakan berbagai jenis resin polimer dan diuji kekuatan tariknya yang nantinya akan dibuat menjadi struktur cladding. Cladding merupakan salah satu teknik dalam konstruksi dengan mengaplikasikan material yang berbeda-beda dengan tujuan membuat suatu lapisan. Sampai saat ini material yang biasa digunakan sebagai cladding adalah kayu, vinyl, batu veneer dan logam. Komposit mulai digunakan sebagai bahan alternatif pengganti struktur cladding dengan  memanfaatkan serat alam dalam hal ini adalah batang pohon pisang sebagai bahan alternative pengganti material cladding pada umumnya. Penelitian ini mengevaluasi sifat mekanik komposit serat alam berbahan baku batang pisang dengan matrik resin poliester dan epoxy melalui uji tarik. Komposit dibuat dengan tiga variasi fraksi volume serat yaitu 30%, 50%, dan 70% untuk mengetahui pengaruh kadar serat terhadap kuat tarik komposit. Hasil uji tarik menunjukkan bahwa peningkatan fraksi volume serat berbanding lurus dengan peningkatan tegangan tarik komposit. Pada fraksi volume serat 30%, tegangan tarik maksimum yang diperoleh sebesar 10,3 MPa, sedangkan pada fraksi volume 50% meningkat menjadi 13,9 MPa. Tegangan tarik tertinggi dicapai pada fraksi volume serat 70% dengan nilai sebesar 19,0 MPa.
