Abstract:This study aims to analyze the Implementation of Traffic Engineering Policy: A Case Study of One-Way and U-Turn Systems in Pekanbaru City and identify inhibiting factors in its implementation. The background of this study…
y is based on traffic problems such as congestion and accidents that are increasing along with the growth of motorized vehicles that are not balanced by adequate road infrastructure. The Pekanbaru City Government through the Transportation Agency has implemented various traffic engineering policies, including the one-way system and the closure of U-Turns at certain points. The method used is a qualitative approach with data collection techniques through interviews, observation, and documentation. The results of the study indicate that the implemented policies have had a positive impact, but their implementation still faces obstacles such as lack of public awareness, limited infrastructure, and less than optimal coordination between institutions. This study recommends the need for more massive socialization and increased synergy between institutions to support the successful implementation of traffic engineering policies.
Abstract:Coal mining, handling, and transportation activities are major sources of airborne particulate matter containing respirable crystalline silica, which poses significant risks to respiratory health. Silicosis remains a serious…
ious occupational and environmental disease affecting not only workers but also communities living near coal-handling areas. Physical environmental factors, including air quality, temperature, humidity, and wind speed, play an important role in influencing dust generation, dispersion, and inhalation exposure. This narrative review aims to synthesize current evidence on the influence of physical environmental conditions on silica exposure and silicosis development, integrating findings from environmental monitoring studies, epidemiological research, and experimental Wistar rat models. A literature search was conducted using major scientific databases to identify relevant peer-reviewed articles published between 2010 and 2024. The reviewed evidence indicates that prolonged or high-intensity exposure to silica dust is strongly associated with chronic pulmonary inflammation and progressive fibrosis. Environmental conditions can exacerbate exposure risk by increasing airborne particulate concentrations and respiratory vulnerability. Experimental studies using Wistar rats provide mechanistic insights into silica-induced lung injury, supporting epidemiological observations in human populations. This review highlights the importance of integrating environmental, occupational, and biological perspectives to improve risk prediction, early detection, and preventive strategies for silicosis in coal-handling regions.
Abstract:This study analyzes the challenges of food security and the policy responses of the government in achieving food self-sufficiency in South Sulawesi in 2025. The research aims to identify production-consumption gaps, distribution…
ribution bottlenecks, and the impacts of climate variability and agricultural policies on food availability, accessibility, and affordability. A mixed-methods approach was employed, combining qualitative and quantitative techniques through household surveys, in-depth interviews with farmers and policymakers, field observations, and secondary data from the Central Statistics Agency and the South Sulawesi Agricultural Department.
The results reveal persistent production deficits for rice and soybeans, while corn has reached a surplus, illustrating structural imbalances among staple commodities. Approximately 62% of respondents reported difficulties in transportation and storage due to inadequate infrastructure, contributing to post-harvest losses and unstable food prices. Government programs such as irrigation development, input subsidies, and farmer training have provided partial benefits, yet 57% of farmers indicated irregular access to such support. Moreover, climate shocks such as El Niño continue to depress yields and increase vulnerability among smallholder farmers. Conversely, social capital, manifested in farmer groups and cooperative networks, has played a significant role in sustaining household food availability and resilience.
The findings suggest that food security in South Sulawesi cannot be addressed solely through production increases. A multifaceted strategy is required, emphasizing rural infrastructure development, climate-smart agricultural innovation, institutional and irrigation reform, and community-based mechanisms that strengthen social capital. This integrative approach provides empirical evidence for policy design and contributes to the broader discourse on sustainable food self-sufficiency in Indonesia.

Abstract:Flooding is a natural phenomenon that can cause disasters for humans, especially in Indonesia and the Philippines, which often experience significant impacts on the economy, transportation, and social life. This research…
aims to analyze the factors that cause flooding in both countries, compare the management policies implemented, and provide recommendations for improved mitigation. The method used is a literature review to collect and analyze various scientific sources. The results show that in Indonesia, factors causing flooding include land subsidence, land use change, and climate change, while in the Philippines, flooding is often triggered by tropical storms and extreme rainfall. Indonesia's response strategy focuses on river normalization and drainage infrastructure, while the Philippines implements a National Disaster Risk Reduction and Management Plan that covers prevention, preparedness, and rehabilitation. Despite these efforts, challenges such as urbanization and land acquisition still hamper the effectiveness of flood management. Recommendations include improving infrastructure, sustainable spatial planning, and community education.

mpetition among driver-partners, which directly affects fluctuations in their income. This study aims to empirically analyze the influence of competition level, working hours duration, and fare policies on the income of GoRide partners in Denpasar City. A quantitative approach was used in this research, with the population consisting of all active GoRide driver-partners in the area. The sample was determined using the Slovin formula with a 10% significance level, resulting in 67 randomly selected respondents. Data were collected through the distribution of structured questionnaires and analyzed using multiple linear regression methods to examine the effect of each independent variable on income as the dependent variable. The results show that the competition variable has a significant negative effect on partner income, indicating that the higher the level of competition, the lower the income earned. Conversely, working hours have a positive and significant effect, indicating that increased working duration directly contributes to higher income. Meanwhile, fare policy shows a positive but insignificant effect, meaning that although there is a statistically positive relationship, the effect is not strong enough to significantly impact income. These findings highlight the importance of efficient management of working hours and strategic adaptation to competition levels as efforts to maintain the economic sustainability of driver-partners. In addition, platform providers are advised to periodically review fare policies to ensure they remain aligned with market dynamics and partner needs, in order to maintain a sustainable income balance.
