Abstract

This study addresses the growing need for efficient and sustainable energy systems through the development of Hybrid Renewable Energy Systems (HRES), which integrate multiple renewable sources with advanced storage technologies to overcome intermittency and reliability issues. The research employs a quantitative modeling and simulation approach, utilizing secondary data on renewable resources, load demand, and component specifications, combined with simulation tools such as HOMER Pro and MATLAB. A multi-objective optimization framework based on metaheuristic algorithms, including Particle Swarm Optimization (PSO) and Non-dominated Sorting Genetic Algorithm II (NSGA-II), is applied to determine optimal system configurations. The results indicate that hydrogen-based configurations provide the highest reliability and lowest emissions, while biomass-based systems offer lower costs but higher environmental impact. Sensitivity analysis reveals that fuel price, load demand, and renewable resource availability significantly influence system performance. The discussion highlights the importance of integrating diverse storage technologies and adopting holistic optimization approaches that consider techno-economic, environmental, and resilience factors. In conclusion, the proposed framework effectively enhances HRES design by producing optimal and realistic solutions, thereby contributing to the advancement of sustainable and resilient energy systems.

Abstract

Computed Tomography (CT) is an essential imaging modality for evaluating head trauma due to its ability to provide detailed cross-sectional images. Image quality, particularly the Contrast to Noise Ratio (CNR), plays an important role in diagnostic accuracy. This study aimed to determine the effect of reconstruction increment variations on CNR values in head trauma CT examinations and to identify the increment that provides the most optimal image quality. This research was a quantitative experimental study conducted at the Radiology Unit of RSUD Prof. Dr. M.A. Hanafiah, SM Batusangkar, in February 2025. The population consisted of all patients who underwent CT brain examinations with clinical head trauma during the study period, totaling 12 patients, of whom five patients were selected as samples using purposive sampling. Secondary image data were reconstructed using two increment variations, 0.7 mm and 1 mm, with identical scanning parameters. CNR values were calculated using Radiant Viewer by measuring regions of interest (ROI), and the data were analyzed using the Shapiro–Wilk normality test followed by the Independent Samples T-Test. The results showed that the mean CNR value for the 0.7 mm increment was 304.52, which was higher than the 1 mm increment with a mean CNR of 288.51. However, statistical analysis demonstrated no significant difference between the two increment variations (p = 0.155; p > 0.05). In conclusion, both reconstruction increments produce comparable image quality in head trauma CT examinations. Nevertheless, the 0.7 mm increment provides higher CNR values and may be considered more optimal for improving image clarity

Abstract

The anteroposterior (AP) projection of the Ossa Pedis examination technique in some hospitals typically uses a perpendicular 0° beam angle, while the theoretical approach uses a 10° cephalad beam angle. This study aims to compare variations in 0° and 10° cephalad beam angles and provide more informative anatomical information. The study used a quantitative experimental approach in the Radiology Laboratory of the Faculty of Vocational Studies, Baiturrahmah University, from June to August 2025. The study involved a population of 79 individuals and a sample size of 3 individuals. Data were collected through radiographic images and then assessed by 5 radiology specialists and 25 radiographers using a questionnaire with a 5-item Likert scale. Question 1 depicts the anatomy of the tarsal bones, Question 2 depicts the space between the metatarsals, Question 3 depicts the lower part of the metatarsals, Question 4 depicts the joint space between the medial cuneiform and the intermedial cuneiform, Question 5 depicts the joint space between the interphalangeal joint, metatarsophalangeal joint, and tarsometatarsal joint. Data processing using SPSS with the Wilcoxon test is presented in figures and tables. Based on the results, the 0° angle produced a lower average value of 17.64, while the 10° cephalad angle produced a more optimal image with a higher average value of 22.72. This image has the advantage of a more open joint space, a more defined metatarsal base, and clearer alignment of the foot bones due to reduced superposition. With a p-value of <0.005, it can be concluded that there are differences in the anatomical images in the anteroposterior (AP) projection pedis examination at 0° and 10° cephalad angles.

Abstract

Nasopharyngeal carcinoma is one of the malignant tumors of the head and neck that requires accurate imaging evaluation, with CT scanning being one of the primary modalities. This study aims to determine the effectiveness of CT-scan parameters for evaluating anatomical information in patients with clinically diagnosed nasopharyngeal carcinoma at the Radiology Department of RST Dr. Reksodiwiryo Padang. The research employed observational methods and in-depth interviews with two radiographers and one radiologist, along with a review of patient CT images. Data were collected regarding patient preparation, examination technique, and the conformity of parameters with theoretical standards. The examination was performed with the patient in a supine head-first position, using a scan area from the MAE to the thoracic vertebrae III, slice thickness of 5 mm, window width of 350, and window level of 40. The results showed that although these parameters differ from theoretical recommendations—which suggest a 2.5-mm slice thickness and a more superior scan range—they were still able to visualize essential anatomical structures, including thickening of the nasopharyngeal roof, intracerebral extension, maxillary sinus opacity, parapharyngeal space, oropharynx, paranasal sinuses, orbital cavity, parotid glands, and mastoid air cells. The diagnostic information was considered sufficient to establish the diagnosis of nasopharyngeal carcinoma; however, the radiologist recommended expanding the superior scan range to evaluate the temporal lobe and intracranial involvement when necessary. In conclusion, the CT-scan parameters used at RST Dr. Reksodiwiryo Padang are effective for assessing nasopharyngeal carcinoma, although further optimization remains advisable

Abstract

A panoramic examination is an examination used to show the upper and lower jaws along with abnormalities in the oral area. The lens of the eye is a sensitive organ that is exposed to radiation during a panoramic examination. The lens of the eye that is exposed to radiation for a long time can cause cataracts that can develop to blindness, therefore to prevent cataracts, BAPETEN No. 6 of 2010 sets a deterministic threshold limit for the chance of cataracts at 15 mSv per year. This study aims to determine how much dose the lens of the eye receives during a panoramic examination and whether the dose received exceeds the established NBD. This type of research is an experimental quantitative study conducted at the Radiology Installation of Andalas University Hospital in September 2025 using a sample of 7 patients. The instruments and materials used are a panoramic machine, TLD and plaster isolation. Dose measurement is done by attaching the TLD to the patient's right and left eyelids then exposed using 73 kV, 10 mA and 10.8 s and then the TLD reading process is carried out. The measurement results obtained in nC units with the final result in the form of an effective dose compared with BAPETEN regulation No. 6 of 2010. The highest effective dose measurement result received by patient 2 was 0.13 mSv and the lowest in patient 1 was 0.095 mSv with an average dose received by all patients of 0.11 mSv. Based on BAPETEN regulation No. 6 of 2010, the deterministic threshold for the chance of cataracts is 15 mSv per year, so the range of effective dose values received by the patient is still within safe limits.

Abstract

The proliferation of digital technologies has engendered a distinctive socio-legal phenomenon wherein private citizens and non-state actors increasingly assume quasi-enforcement roles in the digital realm, a practice broadly characterized as digital vigilantism. This article examines the legal, ethical, and cybersecurity dimensions of digital vigilantism, with particular emphasis on its implications for the rule of law, due process guarantees, and the institutional integrity of state-based law enforcement. Employing a normative legal analysis combined with a systematic review of contemporary scholarly literature published between 2021 and 2025, this study identifies and critically appraises six principal forms of digital vigilantism—namely paedophile hunting, hacktivism, open-source intelligence (OSINT) investigations, social media shaming, cyber-fraud counter-operations, and organized digital patrols—across multiple jurisdictions including Indonesia, India, China, Russia, the United Kingdom, and the European Union. The findings reveal a persistent doctrinal tension between the perceived legitimacy of public digital enforcement and fundamental legal principles including presumption of innocence, the prohibition of arbitrary punishment, and privacy rights. This article argues that the absence of a coherent regulatory framework governing digital vigilantism constitutes a significant lacuna in contemporary cybersecurity governance, and proposes a multi-layered co-regulatory model that balances civic participation with institutional accountability. The study contributes to the nascent body of comparative digital law scholarship and offers actionable policy recommendations for legislators, law enforcement agencies, and civil society organizations.

Abstract

The mining industry is both a major contributor to climate change and highly exposed to climate-related risks, making climate risk disclosure (CRD) a critical tool for enhancing corporate transparency and accountability. However, despite increasing reporting practices, the quality and consistency of climate disclosures remain uneven. This study aims to analyze how CRD contributes to transparency and accountability in the mining sector. The research employs a qualitative approach using a systematic literature review and document analysis of relevant academic studies and reporting frameworks such as TCFD and GRI. Data were collected through structured stages of identification, screening, eligibility, and inclusion, and analyzed using thematic and content analysis. The findings indicate that while climate disclosures are increasingly adopted, many remain symbolic and lack integration with financial impacts and strategic decision-making. High-quality disclosures—characterized by comprehensive emission reporting, governance involvement, and adherence to international standards—enhance transparency and accountability. However, challenges such as greenwashing, inconsistent standards, and weak market responses persist. In conclusion, climate risk disclosure has significant potential to strengthen transparency and accountability in the mining industry, but its effectiveness depends on the depth, consistency, and substantive integration of disclosed information.
