Abstract

Road transportation accidents are a significant public health and safety issue worldwide. In Australia, regarding transport-related deaths, the age-standardized rate was higher in one specific year compared to the preceding year. This study aims to make visualization of crash data in Australia play a crucial role in understanding the country's current state of road safety and developing strategies to improve it. Data visualization techniques are essential in understanding and addressing road safety in Australia. New South Wales has the highest number of accidents in Australia, with 16,293 cases. Accidents in New South Wales are projected to decline gradually over the next three years. The peak time for accidents is 3 PM on weekdays, with males being more involved than females. Drivers are the most involved road users in accidents. Implementing targeted road safety initiatives, gender-specific awareness campaigns, and driver safety programs can help reduce accidents in New South Wales and create a safer environment for all road users. By analyzing accident data visually, patterns and trends can be identified, leading to targeted interventions and improved safety measures to reduce the number of accidents and fatalities on the roads.

Abstract

Air pollution is a serious problem experienced by all countries because it can cause many health problems and even death. The situation in countries of the Association of Southeast Asian Nations or ASEAN is the high air pollution-related mortality rates, especially in countries like Laos, Myanmar, and Cambodia, which face elevated risks due to poor air quality. Raising public awareness about air pollution requires a concerted effort involving various strategies and channels. The paper provides research findings on air pollution, including data on air pollution-related deaths, regional variations, and forecasting using Tableau software. It underscores the need to address air pollution challenges, particularly in ASEAN, to protect public health. Due to industrialization, ASEAN countries are grouped into high and low mortality clusters and ongoing air pollution challenges in Asia. Continued efforts are needed, especially in Myanmar, Cambodia, the Philippines, and Laos.

Abstract

Village administration services are essential in a village's progress and villagers' satisfaction with village officials. There are many villages in Indonesia where services still need to be more optimal because they have limitations in disseminating information, unclear procedures, and the status of service applications that cannot be monitored. Mobile-based applications can optimize village administration services, which can bridge between villagers and village officials. From the results of several previous studies, the Rapid Application Development (RAD) model is relevant to be applied in designing Android-based village service applications with the Flutter framework. The SHA-512 algorithm is implemented to increase security by hashing passwords to strengthen database security in village service applications. The application produced in this research has been tested using the User Acceptance Test (UAT) method, and it was concluded that this system is suitable for use by villagers and improves Cihuni village services.

Abstract

The new normal has posed significant challenges for students in maintaining their health. To address this issue, this study aimed to examine the awareness of university students in maintaining their health during this period using clustering and Naïve Bayes methods. The results of the study revealed two distinct clusters, "Aware" and "Not Aware," indicating that Indonesian students have varying levels of awareness regarding health precautions during the new normal. Most students are in the "Aware" cluster, suggesting a positive trend in health-conscious behavior among students in Indonesia. The Naive Bayes method was used to validate the cluster analysis, which resulted in an overall accuracy of approximately 96.25%. The study also found that the students are generally trying to maintain their health during the new normal, with most scoring between moderate and good. However, there are differences in the levels of effort put in by different age groups, with those aged 22 scoring lower. Moreover, students are generally making a good effort to maintain their health in public places during the new normal, but again, those aged 22 had the lowest scores. In terms of healthy food consumption, most students across all age groups scored a level of moderate consumption. The purpose of these findings is to inform policymakers and healthcare providers to develop sustainable programs for improving health awareness among students and addressing the challenges presented by the new normal.

Abstract

Given the dearth of prior research on the practical implementation of money management strategies in the foreign exchange market, making it arduous to ascertain profitable money management comparisons, this study places its focus on the amalgamation of money management strategies and technical indicators. The research specifically explores the utilization of two money management strategies, namely reverse martingale, and cumulative win strategy, in conjunction with Ichimoku Kinko Hyo serving as the chosen technical indicator. The primary aim of this research endeavor is to identify the most lucrative money management combination within a three-year timeframe. The study centers on the EURUSD currency pair, employing the H1 timeframe for analysis. The research methodology encompasses four essential stages: data collection, data processing, strategy testing, and result analysis. Subsequently, the acquired EURUSD data will undergo amalgamation utilizing the One-Way ANOVA method to determine the presence of statistically significant disparities between the two combinations. The outcomes of this investigation underscore the supremacy of the cumulative win strategy and Ichimoku Kinko Hyo combination, exhibiting a remarkable Return on Investment (ROI) surpassing alternative combinations, soaring to an impressive figure exceeding 2860%.
