Abstract

The Kampar River has enormous benefits for people's lives, including the availability of non-renewable resources such as sand and stone, which are utilized without permission as raw materials for building. The high demand for river sand and stone and modern sand mining technology exacerbate environmental impacts, especially the width of the Kampar River. This study was conducted to determine the impact of changes in river width caused by illegal sand and stone mining activities in the Kampar River. This research uses a quantitative approach with direct observation methods, interviews, and literature studies. This research was conducted from May to August 2024 in Padang Luas Village, Terantang Village, Parit Baru Village, and Kualu Village, Tambang District, Kampar Regency. The results of this study indicate that illegal sand and stone mining activities in the Kampar River cause significant widening of the river, in addition to increasing turbidity and siltation of the river due to cliff collapse. The impact of changes in river width is worst in Parit Baru Village, which has the most mining locations compared to the other three villages. The highest turbidity value is found at station 3, and the shallowest river depth is at station 2. Illegal sand and stone mining has a real negative impact on the environment, especially on the physical condition of the Kampar River, which is marked by the siltation and widening of the river from year to year.

Abstract

Sustainable Urban Drainage Systems (SUDS) are considered an innovative approach to urban water management, but their application in Indonesia is still very limited. Aim: This study was aimed to analyze the impact of land use change on runoff coefficient and its implication for socio-economic resilience in post-flood conditions in Kuantan Tengah District, Riau Province. Methodology and results: The research applied a spatial-hydrological and socio-economic approach, integrating drone imagery, GIS-based land classification, runoff coefficient analysis, field drainage assessment, and community surveys. Results revealed that the average runoff coefficient (Cr) increased to 0.57 due to land conversion into impervious surfaces, especially residential and road areas. This condition led to inadequate drainage capacity and contributed to urban flooding. Socio-economic impacts identified include infrastructure damage, income loss in local businesses, health problems, and psychological stress. SWOT analysis highlighted institutional strengths and public awareness, but also emphasized weak ecosystem-based management. Conclusion, significance and impact study: A Sustainable Urban Drainage System (SUDS) model was proposed to overcome these challenges, combining green infrastructure, zoning policy, SOP (standard operating procedures) for drainage maintenance, and community participation. This study provides a novel integrative framework for urban flood risk mitigation based on hydrological and socio-economic indicators and offers policy insights for sustainable spatial planning in flood-prone regions.  The solutions offered directly support several Sustainable Development Goals (SDGs), particularly SDG 11 on Sustainable Cities and Communities, SDG 6 on Clean Water and Sanitation, and SDG 13 on Climate Action.

Abstract

Global warming is one of the natural phenomena that impacts the flow of the Siak River. Among the impacts are sea level rise and seawater intrusion. These changes also affect the distribution of flora and fauna from the sea into the River. This study aims to determine the structure of mangrove vegetation communities and water quality conditions found in the tidal area of the Siak River. This research was conducted in October 2024. The research location consists of 4 stations, each station was placed in 3 plots following the flow of the River, with a distance of 100 m between each plot. Each plot has a size of 10 x 10 m. This research was conducted using the survey method. The study identified six mangrove species, consisting of 2 true mangroves and four associated mangroves. The density of mangrove vegetation in the research location is categorized as good, with the highest number of 1933.33 ind/ha at stations I and II, and the lowest at 1633.33 ind/ha at station IV. The results of the critical value index indicate that Sonneratia caseolaris plays a vital role in all research stations, with the highest percentage of 252.90% at station II and the lowest 230.20% at station I. The results of the ANOVA test analysis of density between stations showed a significant value. 0.148, which states that there is no significant difference between the four stations. Water quality measurements showed a temperature value of 28-30 °C; salinity 0 ppt, and pH 5.4-6. Sediment types at all stations were dominated by mud. The highest average organic matter was in station I, at 11.90%, while the lowest was in station II, at 6.83%. The value of Total Suspended Solid (TSS) at the study site ranged from 0.0153 to 0.1640 mg/L. Station II was dominated by muddy sand, and station III was dominated by sand with a total sediment organic matter content of 0.46-23.33%. The nitrate content found ranged from 0.0146-0.0583 mg/l, and the phosphate ranged from 0.0465-0.0996 mg/L. The linear regression test results for mangrove density with TSS, organic matter, and nutrient (nitrate and phosphate) content showed a weak relationship

Abstract

Sustainable city development is one of the strategic agendas in regional and spatial planning, especially in urban areas that have historical value and environmental potential, such as Siak Sri Indrapura. One important instrument in supporting sustainable development is the Suitability of Space Utilization Activities (KKPR), which functions to ensure that space use is in line with spatial planning policies and sustainability principles. This research aims to analyze the role of KKPR in realizing sustainable city development in Siak Sri Indrapura, by emphasizing environmental, social and economic aspects. The approach used is qualitative and quantitative methods, through document analysis, interviews with stakeholders, and field surveys. The study results show that the implementation of KKPR in Siak Sri Indrapura contributes significantly to optimizing space functions, preserving cultural heritage areas, and reducing environmental impacts. However, challenges such as limited spatial data and lack of coordination between sectors need to be overcome to increase the effectiveness of the KKPR. The proposed policy recommendations include strengthening monitoring systems, developing technical capacity, and integrating KKPR with community-based development programs. This study provides scientific and practical contributions in efforts to create a competitive, inclusive and environmentally friendly city
