This study was conducted to examine the effectiveness of Kevlar as a structural material in Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs), particularly those designed with winglet innovations. In UAV development, material selection plays a crucial role since it directly affects flight performance, fuel efficiency, and the overall durability of the aircraft structure. Kevlar is widely recognized as a lightweight yet highly durable material, making it an interesting candidate to replace more conventional options such as aluminum and carbon fiber composites. Two approaches were applied in this research: numerical simulations using aerodynamic software and experimental testing on a prototype wing and winglet reinforced with Kevlar. The analysis focused on comparing lift, drag, total aircraft weight, and fuel consumption between Kevlar-based structures and conventional materials. The results demonstrate that Kevlar significantly improves aerodynamic efficiency and extends flight endurance due to its lower weight. Moreover, Kevlar exhibits superior resistance to dynamic loads and impacts, which are critical during certain flight conditions. However, challenges remain in terms of higher production costs and more complex manufacturing processes compared to traditional materials. Despite these limitations, the findings provide valuable insights for developing more efficient and durable MALE UAVs, while also encouraging innovation in aerodynamic design through the application of winglet technology.

Sidewalks are a crucial element of urban infrastructure that support pedestrian mobility. However, on Jalan Dr. Mansyur, Medan Selayang, sidewalk conditions present various problems, such as damaged surfaces, a lack of accessibility facilities, and the presence of street vendors occupying the lanes. This study aims to analyze the impact of sidewalk quality on pedestrian activity by examining three main factors: the physical condition of the sidewalk, environmental safety, and accessibility. Using a mixed methods approach, the sample for the quantitative approach was taken using a stratified random sampling method with a total of 150 respondents. Quantitative data were analyzed using descriptive statistics and SPSS software, while qualitative data were collected through in-depth interviews with key informants. The results showed that sidewalk accessibility had the strongest relationship with pedestrian activity (correlation coefficient 0.72), followed by the physical condition of the sidewalk (0.68) and environmental safety (0.55). Minimal accessibility factors, such as the lack of special lanes for the disabled, proved to be the main obstacle to pedestrian activity. In addition, the damaged physical condition of the sidewalk and the use of sidewalks for activities that are not in accordance with their function further reduce user comfort. Based on these findings, key recommendations include physical improvements to sidewalks with regard to the principles of universal accessibility, including the addition of dedicated lanes for the disabled, repair of damaged surfaces, and reconfiguration of spaces to discourage use by street vendors. The government needs to ensure adequate street lighting to improve user safety. The public is expected to maintain the function of sidewalks by utilizing them according to their intended purpose, while future researchers are advised to explore the impact of sidewalk improvements on broader social and economic aspects, as well as consider the integration of technology in sidewalk design and management. The conclusion of this study is the need for collaborative action between the government, the community, and other relevant parties to create inclusive sidewalk infrastructure that supports active mobility.

This study aims to analyze the effect of dividend policy and profitability on shareholder wealth in companies listed in the High Dividend 20 Index on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The research adopts a quantitative approach using secondary data obtained from the official IDX website (www.idx.co.id ).The population includes all issuers in the High Dividend 20 Index during the research period, and purposive sampling was applied to select 12 companies as the final sample. Data analysis techniques involved classical assumption testing, multiple linear regression, and hypothesis testing to determine the influence of independent variables on shareholder wealth. The statistical analysis was performed using EViews 12 Student Version software.The findings reveal that the Dividend Payout Ratio (DPR) does not have a significant effect on shareholder wealth, implying that dividend distribution is not the main factor influencing investor value in the observed companies. In contrast, Return on Assets (ROA) demonstrates a significant positive effect, which highlights the importance of profitability in driving shareholder wealth. These results suggest that investors may place greater emphasis on a company’s ability to generate earnings rather than its dividend distribution policy when assessing firm value. The study contributes to the literature on dividend policy and corporate performance by providing evidence from the Indonesian capital market, particularly within firms that consistently distribute high dividends.

Patriarchy in the modern era still persists despite continuous efforts to achieve gender equality across various aspects of life, including education, the workplace, and social interactions. Its presence is often reinforced through mass media, particularly in television series. The drama series “Bid’ah” vividly portrays the impact of patriarchy on women’s lives, both in domestic settings and in the public sphere.

This study aimed to determine and analyze the influence of financial ratios on profit changes in telecommunications companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The financial ratios used in this study encompass four main groups: liquidity ratios, solvency ratios, activity ratios, and profitability ratios. This study employed a quantitative approach with an associative nature because it attempted to examine the relationship and influence between these financial variables on profit changes. The population in this study comprised all telecommunications companies listed on the IDX, while the sample selection was conducted using a purposive sampling technique with specific criteria, resulting in 15 eligible companies. The research data were then analyzed using panel data regression using EViews 12 software, with the best model selected being the Random Effect Model (REM). The results showed that simultaneously, liquidity, solvency, activity, and profitability ratios significantly influenced profit changes, thus concluding that the company's overall financial performance plays a significant role in determining the dynamics of profit generated. However, partial test results showed that the influence of each ratio was different. The solvency ratio has a significant negative effect on profit changes, indicating that the higher a company's debt level, the greater the risk of profit decline. Conversely, the profitability ratio has a significant positive effect, confirming that a company's ability to generate net profit is a major factor in increasing profit changes. Meanwhile, the liquidity ratio and activity ratio were not shown to have a significant effect on profit changes, indicating that short-term liquidity and operational efficiency are not sufficient to be the primary determinants in driving profit changes in the telecommunications sector.
