Abstract

Archery performance as a precision sport is determined by a complex interaction between psychological and physiological factors. Concentration, as a crucial factor, can be objectively measured through electroencephalography (EEG) by detecting beta waves. However, current coaching practices disproportionately emphasize physical aspects while systematically ignoring concentration as a crucial psychological factor. Generally, studies assess performance through aggregate scores without distinguishing between two fundamental dimensions: accuracy and precision. This study aims to analyze the relationship between concentration levels measured through beta band power activity using EEG and shooting performance in archery athletes, focusing on shooting accuracy and shooting precision. This study offers empirical contributions about the relationship between concentration and two dimensions of shooting performance, develops a methodological validation that integrates EEG monitoring with smart bow technology, and establishes a practical foundation for developing concentration-based training programs in archery. The research subjects consisted of 12 novice archery athletes. EEG data were acquired with electrodes positioned at AF7 and AF8, monitoring beta band power during shot execution. Pearson’s correlation was used to analyze the relationship. The results showed a shot accuracy with an average score of 131.17, while precision showed an average SRD of 11.00 cm. Beta band power had a mean of 39.18 µV². Correlation analysis revealed a non-significant positive relationship between beta power and accuracy (r = 0.145, p = 0.652), as well as a non-significant negative relationship with precision (r = -0.327, p = 0.300). Study findings show that beta wave activity alone does not serve as a significant predictor of shooting performance in novice archers. However, the differential correlation pattern (positive for accuracy, negative for precision) confirms that these two dimensions are influenced by different psychophysiological mechanisms.

Abstract

Media sosial menjadi ruang utama dalam mengekspresikan opini publik terhadap kebijakan pemerintah, termasuk kebijakan konversi kompor gas ke kompor induksi di Indonesia yang menimbulkan pro dan kontra. Meskipun analisis sentimen telah banyak digunakan untuk mengevaluasi persepsi publik terhadap proyek, belum terdapat kajian yang secara sistematis memetakan metode yang paling relevan untuk konteks kebijakan publik di Indonesia. Penelitian ini bertujuan untuk mengidentifikasi dan mengevaluasi pendekatan analisis sentimen dalam studi proyek sebagai dasar metodologis untuk penelitian lanjutan mengenai opini publik terhadap kebijakan kompor induksi. Penelitian menggunakan pendekatan Systematic Literature Review (SLR) dengan metodologi PRISMA terhadap 15 artikel terindeks Scopus periode 2016–2022. Analisis difokuskan pada pemetaan pendekatan metodologis dan pola penggunaannya. Hasil menunjukkan bahwa pendekatan berbasis leksikon dan machine learning, khususnya Support Vector Machine (SVM), merupakan metode yang paling dominan digunakan. Selain itu, Latent Dirichlet Allocation (LDA) sering dimanfaatkan sebagai metode pendukung untuk mengidentifikasi topik atau isu utama dalam data opini publik. Temuan ini menunjukkan bahwa kombinasi klasifikasi sentimen dan pemodelan topik menjadi pola metodologis yang paling umum dalam literatur. Penelitian ini berkontribusi dalam menyediakan pemetaan metodologis yang dapat menjadi rujukan bagi penelitian empiris mengenai analisis sentimen kebijakan kompor induksi di Indonesia.

Abstract

Introduction: Occupational safety and health (OSH) is a key pillar in creating a productive and sustainable work environment, especially in the high-risk manufacturing sector. As global demands for Environmental, Social, and Governance (ESG) principles increase, the integration of safety culture and sustainable technology is an important strategy to strengthen the protection of workers' health while supporting industrial sustainability. Method: A quantitative approach was used by distributing questionnaires to 200 workers from various categories of manufacturing industries. The analysis used included correlation tests, multiple linear regression, and scenario simulations of technological improvements and recycling efficiency of personal protective equipment. Result: The main variables analyzed were discipline in wearing PPE, consistency, reward-punishment, and the application of wearable technology and environmentally friendly PPE. The regression results show that the discipline of using PPE is the most significant factor in shaping occupational safety culture (p = 0.001). Although the technology and reward variables are not statistically significant, the simulation shows that increased investment in safety technology can accelerate the growth of safety culture and indirectly strengthen occupational health protection.The implementation of sustainability principles, such as the use of environmentally friendly PPE materials and recycling programs, is also proven to reduce the impact of industrial waste and contribute to the Environmental aspect of ESG. Conclusion: While lowering the effect of industrial waste, the simulation reveals that higher investment in technology and recycling efficiency might hasten the change of safety culture from reactive to proactive. This study theoretically expands the safety culture approach to be more predictive and sustainable under the ESG framework, so improving its sustainability. Practically, these results give a basis for industrial policies to create OSH strategies compatible with digital transformation and world sustainability goals.

Abstract

Introduction: Safety?and security are important considerations for nature-based tourism, even more so if destinations are prone to disasters that reinforce the risk of transport, environmental and activity-related hazards. Kulon Progo, Yogyakarta’s Mudal River Ecotourism reflects these issues through the presence of steep and curving roads, unpredictable hydrometeorological conditions and insufficient safety facilities which together increase risk exposure during travel to?the destination as well as when executing activities at site. Methods: This research used a?qualitative case study approach that purposively juxtaposes the HIRADC framework with the DRR principles in a complex ecotourism context. Data were gathered through fieldwork, semi-structured interviews with managers, tourists and government organizations, document analyses; the risk assessment was based on the AS/NZS 4360:2004 standard considering probability (A–E) and?severity (1–5) scales. Results: The findings identified critical hazards along the travel route (landslides, slippery and narrow roads, brake failure on steep slopes, and interaction with village traffic) and within the tourism area (slipping on rocks, sinking in deep pools, being swept away by strong currents, falls from heights, structurally vulnerable bridges, and animal bites). Most hazards were classified as high risk, particularly those associated with aerial recreation and landslide-prone access, leading to the management of a layered control package that combines engineering measures, administrative procedures, tourist safety education, and community-based monitoring aligned with disaster risk reduction strategies. Conclusion: This study demonstrates how the application of the HIRADC framework and disaster risk reduction concepts can strengthen tourism safety governance in nature-based destinations exposed to geological and hydrometeorological hazards. The proposed safety management roadmap provides a practical reference for destination managers and policymakers and offers insights that can be applied to developing more resilient risk management models in similar ecotourism contexts.

Abstract

The growth rate of the cosmetics industry shows good development, reaching 9.39% in 2020. With so many cosmetic products in the market, consumers must be more careful in choosing the cosmetic products. In addition to the safety factor, the halalness of cosmetics also needs to be considered, especially for Muslim consumers. This research aims to create a halal detection model in cosmetics by implementing one of the deep learning methods, namely convolutional neural network (CNN). .Previous research has successfully created a halal detection model on Korean cosmetics using CNN with an accuracy rate of 95.56%. This research intends to develop previous research by adding classes and the number of datasets. CNN will be used to create a halal detection model in cosmetics by learning the input features in the form of the image of cosmetic ingredient to determine its halalness. Classification is done based on two classes, which are Halal and Shubhat. The results show that the CNN model gets an accuracy value of 98.66% with a loss of 0.0615 in classifying the halalness of cosmetics. Model testing using the testing dataset gets an accuracy value of 98.67%. The F1-score value in each class is 98.66% for the halal class and 98.67 for the shubhat class. The CNN model that has been created is appropriate because it shows high accuracy and low loss on training, validation, and testing data without experiencing overfitting or underfitting,

Abstract

The efficiency of palm oil harvesting is crucial to ensuring optimal yield and quality of fresh fruit bunches (FFB). Traditional manual harvesting methods often result in inconsistent outcomes due to human error and subjectivity in ripeness evaluation. This study proposes an intelligent, image-based harvesting decision system that utilizes Convolutional Neural Networks (CNN) and Support Vector Machines (SVM) to automate the classification of palm oil FFB ripeness. High-resolution images of palm fruit are processed using Python-based frameworks (Google Colab 3.10.12, YOLOv8) to extract features such as color and texture, which are then used to train the CNN and SVM models. The system architecture includes stages for image acquisition, preprocessing, feature extraction, classification, and decision-making. Both CNN and SVM were evaluated for performance using accuracy, precision, recall, and F1-score. The experimental results demonstrated high classification accuracy, with CNN achieving an average of 0.97 and the highest result recorded at 0.89. The system significantly enhances harvesting decision accuracy and reduces dependence on manual inspection. This study demonstrates the viability of using deep learning and machine learning algorithms for real-time agricultural decision-making. The integration of CNN and SVM not only improves productivity but also contributes to sustainable practices by reducing waste and labor intensity. The proposed system offers a scalable solution that can be adapted for broader smart farming applications, supporting national goals of digital transformation and energy efficiency in agriculture.
