Abstract

Rapid urbanization has significantly contributed to environmental degradation, particularly in coastal cities. In Semarang’s Tanjung Mas Village, frequent coastal flooding is a pressing issue, driven by rising sea levels, land subsidence, and inadequate drainage infrastructure. Therefore, this study aims to identify coastal flood hazards in Tanjung Mas and evaluate the efficiency of evacuation routes to improve disaster response strategies. Using GIS-based spatial analysis, flood modeling, and network analysis, high-risk zones, and proposed optimized evacuation pathways are identified. In line with these results, the northern and central sections of Tanjung Mas are the most vulnerable, with densely populated residential and industrial areas at the highest risk. A comparison with Seocho and Gangnam District, South Korea, and Mueang Nakhon Si Thammarat District, Thailand, highlights key differences and similarities. In South Korea and Thailand, the proposed evacuation routes have not adequately considered human behavioral factors. In contrast, a GIS-based specifically tailored to Tanjung Mas, integrating real-time flood updates and optimized route mapping to improve evacuation strategies is proposed. By drawing insights from international case studies, this study contributes to developing adaptive flood evacuation systems applicable to other coastal cities facing similar challenges. These results emphasize the importance of integrating real-time data and community-based planning to enhance disaster resilience and response strategies in urban coastal environments. The approach delivers a novel approach to combining disaster preparedness analysis and flood modeling in the results of a proposed evacuation route in the industrial coastal area.Received: 2024-07-19 Revised: 2024-08-20 Accepted: 2025-03-26 Published: 2025-04-28

Abstract

This action research aimed to improve the status of water, sanitation, and hygiene (WASH) and related knowledge in the coastal Kalia and Lohagara upazilas of Narail district in Bangladesh. The project offered a total of 606 safe water options, 950 household latrines, 50 latrines for disabled individuals, five community latrines, and 20 sanitation blocks. Further, created WASH awareness through organizing courtyard meetings and folk song events, distributing awareness posters, WASH pouts, school routines, school WASH posters, installing billboards, and painting community walls. Female adults from 534 randomly selected households’ were interviewed during the base-line survey and end-line survey. This study revealed that the rate of use of deep tube wells and hygienic latrine—that is, septic tanks and leak-free ring slab latrines—has increased substantially in both areas. Besides, perceptions about health problems associated with drinking arsenic-contaminated water improved considerably. Furthermore, knowledge about hygienic latrine improved by about 25 percentage points. Perception about hygienic hand washing and post-defecation hand washing (both hands with soap) practice improved but still needs to work on improving before eating both hand washing with soap practice. Therefore, suggesting further education and reinforcement on the importance of washing hands with soap before eating. This study also explored that knowledge about the mode of diarrheal transmission improved at the end of the intervention. However, to maintain favourable impressions and overcome difficulties in comprehending diarrhoea transmission mechanisms, particularly with regard to water, further education and focused interventions are needed.Received: 2024-07-28 Revised: 2024-08-20 Accepted: 2025-03-11  Published: 2025-05-26

Abstract

The increase in tourist visits to Panyaweuyan terrace is observed to have a positive impact. However, negative effects are being felt by farmers in the surrounding areas of the tourist site. Therefore, this research aimed to examine the socio-economic characteristics of farmers and perception concerning impact of Panyaweuyan terrace tourism activities on the socio-cultural, economic, and environmental aspects. The basic method of this research was a survey, including a sample of farmers for interviews. Additionally, primary data were collected through in-depth interviews with several informants. The Likert scale data analysis was performed using quartile (Q) method and analyzed descriptively and qualitatively. The results of the research showed that the socio-economic conditions of farmers around Panyaweuyan terrace tourism area were quite diverse. According to perception of farmers, tourism activities in the area had a positive impact on both the socio-cultural and economic aspects of community. However, farmers still perceived negative impact on the socio-cultural and environmental aspects. Based on these results, management should be community-based and sustainable to minimize the negative impact of Panyaweuyan terrace tourism.Received: 2024-08-04 Revised: 2024-08-20 Accepted: 2025-04-11 Published: 2025-04-28

Abstract

Flood is one of the most frequent natural disasters in Indonesia and worldwide. Therefore, this study aimed to compare and evaluate flood-prone mapping model using Height Above Nearest Drainage (HAND) and Topographic Wetness Index (TWI) model in data-scarce areas. HAND and TWI models were used to estimate flood-prone level, with field survey and image interpretation as primary methodologies. The data used was Digital Elevation Model (DEM) imagery with a resolution of 10 meters, incorporating elevation, slope, and hydrological parameters namely flow accumulation, direction, and distance. The mapping flood-prone areas were categorized as very prone, prone, moderate, not prone, and very not prone. The results showed that there were differences between HAND and TWI models in terms of area and percentage. The differences in flood inundation characteristics produced by HAND model were mainly due to variations in elevation and proximity to drainage channels. In contrast, TWI model focused on topography, soil moisture, and runoff potential. The differences between the two models also emphasized the importance of terrain characteristics in model predictions. The comparable predictive ability of HAND and TWI models presents an alterReceived: 2024-08-15 Revised: 2 024-09-12Accepted: 2025-03-22 Published: 2025-05-26

Abstract

The Jagir River estuary system constitutes a significant ecosystem in Surabaya that sustains the livelihoods of the surrounding communities. Despite its importance, the river is subjected to substantial pollution originating from domestic and industrial waste. Therefore, this study aims to investigate the patterns of physicochemical interactions between lead (Pb) in the Jagir River estuary system. Water and sediment samples were collected at 5 strategic points, and the concentration of Pb was analyzed using Inductively Coupled Plasma optical emission spectrometry (ICP-OES). The correlation between Pb and various environmental parameters (temperature, salinity, DO, pH & TDS) was analyzed using Principal Component Analysis (PCA). The results showed that the concentrations of Pb in the water column and sediment were 0.1637 – 1.8905 ppm and 0.0735 – 0.2349 ppm, respectively, exceeding the established quality standards for water. Pb content in the waterbody exhibited an increasing trend from upstream to the sea. These results show the salinity and tidal parameters as characteristic features of the Jagir River estuary system, which influence Pb content in water and sediment. The distinct characteristics of this estuary system vary for each region or location, showing that the results can contribute to the development of environmental policies and monitoring of water quality.Received: 2024-08-15 Revised: 2024-09-12 Accepted: 2025-01-25 Published: 2025-04-28

Abstract

This study aimed to develop a model for accelerating the transition to  green economy through the implementation of a climate village focused on food security. It introduced a children-friendly digital education program designed to enhance out-of-class learning on climate change mitigation and adaptation. This study also emphasized the integration of Proklim activities within designated areas to minimize the adverse effects of climate change. A survey method was conducted in Sukoharjo Regency with a sample of 160 respondents of Proklim activists. Primary data were collected using questionnaires, FGDs, and quantitative interviews, while secondary data were collected through documentation. The data were analyzed using geographic information systems, structural equation model PLS, vs code software, MySQL, construct, animate, and travel cost methods. The results showed that accelerating the transition to green economy through a food security-based climate village program involved a combination of adaptation, mitigation, and sustainability efforts. The adaptation measures focused on controlling drought, floods, and landslides, enhancing food security, and managing climate-related diseases. Meanwhile, mitigation efforts included effective waste management for both solid and liquid waste, adoption of renewable energy, conservation practices, energy efficiency, reduction of greenhouse gas emissions, agricultural innovation, and the preservation of vegetation cover. Sustainability was reinforced through the establishment of community groups, promotion of self-reliance, independent funding initiatives, gender-inclusive participation, capacity-building programs, external support, and the development of activities that generate social, economic, and environmental benefits. Digitalization in education is implemented through the Proklim digital platform, KampungIklim.com, which offers out-of-class learning resources on climate change mitigation and adaptation. Proklim activities serve as pilot sites for educational tourism, promoting sustainability by integrating economic value into existing initiatives, including the development of Proklim-based tourism villages.Received: 2024-08-15 Revised: 2024-11-15 Accepted: 2025-02-19 Published: 2025-04-29

Abstract

Carbon monoxide (CO) and nitrogen dioxide (NO2) are the primary pollutants found in the air. Based on the results of the study of predecessor researchers, it is known that human activity factors cause spatial and temporal changes in primary pollutants in the air, while natural factors, such as rainfall changes during the transition of seasons, have not been studied further. This study was conducted to examine the impact of rainfall changes on spatial patterns of primary pollutants (CO and NO2). The Special Region of Yogyakarta (DIY), Indonesia was chosen as a research area. The data used were remote sensing data, namely CHRIPS (Climate Hazards Group InfraRed Precipitation with Station data, NRTI (Near Real Time) / L3_CO data, and NRTI / L3_NO2 data. The data were analyzed using cloud computing methods based on Google Earth Engine and statistical analysis. The results showed that the dynamics of rainfall patterns had an impact on changes in CO and NO2 concentrations although it was not significant. Based on the study, it is known that an increase in rainfall of 1% causes a decrease in CO concentration of 1.935 x 10-5 mol/m2 and a decrease in NO2 concentration of 3.151 x 10-9 mol/m2.  A study conducted in southern India also concluded that higher rainfall has the potential to reduce CO and NO2 concentrations. The impact of rainfall pattern dynamics presented quantitatively in this study is a new finding, because there have not been many studies that explain the impact of rainfall pattern dynamics on CO and NO2 quantitatively.Received: 2024-08-24 Revised: 2025-01-02 Accepted: 2025-02-16 Published: 2025-05-26

Abstract

Coastal areas are classified as highly vulnerable because they are always tied to changes in the global aquatic environment. The ecosystem dynamics are increasingly complicated and complex as a result of interactions with other systems on land. This phenomenon is very visible in the coastal areas of Bantul Regency and Kulon Progo Regency. We use Sentinel-2 satellite image interpretation in the period 2013-2022 as a historical record of land use change, and then explore it with Niklas Luhmann's social system theory to understand how communities and government mean the ecological system represented by activities in coastal areas. The results showed that the community and the Government massively changed the original ecosystem of pes-caprae with the dominant afforestation of shrimp cypress. For the community, afforestation is assumed to support production agriculture, from subsistence agriculture. For the government, afforestation is a misconception about reforestation and protecting vital infrastructure such as Yogyakarta International Airport. The main capital for change is technology and its knowledge, and economic capital obtained from production. The economic capital obtained is used for social transformation, including eliminating the stigma of poor, uninformed, and inferior coastal communities. The results achieved change the meaning of land from previously only to support daily livelihoods to production factors that have very high economic and social value. Any attempt to change the establishment of the social and economic system will be met with strong resistance from the community. Under these conditions, the sustainability discourse that we are developing is to build an institutionalized knowledge system, which is carried out repeatedly and continuously, which is important for the community to understand because its dynamics will continue to develop in the future.Received: 2024-10-23 Revised: 2025-02-07 Accepted: 22025-04-16 Published: 2025-04-30

Abstract

Contamination of water resources by heavy metals poses significant environmental and public health challenges worldwide, especially in developing regions like Nigeria. This study investigated the concentration levels of heavy metals in sedimentary formations across selected local government areas in Kogi State, Nigeria, with the aim of assessing seasonal variations and potential health risks. Four local government areas were strategically chosen to represent major sedimentary formations in the state. Water samples were systematically collected during both dry and wet seasons, yielding a total of 60 samples per season for laboratory analysis. The samples were analyzed for 10 physico-chemical parameters, 3 biological indicators, and 10 heavy metals using standard laboratory procedures. Data were analyzed using SPSS 20.0 for descriptive statistics and further subjected to inferential statistics, including Analysis of Variance (ANOVA) and Student t-test, to assess variations across seasons and formations. Results revealed that concentrations of heavy metals such as zinc (Zn), arsenic (As), mercury (Hg), nickel (Ni), cadmium (Cd), iron (Fe), and magnesium (Mg) exceeded both WHO and Nigerian Standards for Drinking Water Quality (NSDWQ) limits, particularly during the wet season, indicating significant seasonal variability and potential ecological risks. The findings highlight the critical need for effective environmental management and pollution control measures in the study area. The study's novelty lies in its comprehensive seasonal and spatial assessment of heavy metals across sedimentary formations, providing baseline data for policymakers. In comparison with similar studies in Nigeria and globally, these results emphasize the urgent need to improve waste management practices and strengthen water quality monitoring systems. Received: 2023-07-16 Revised: 2025-01-16 Accepted: 2025-08-05 Published: 2025-08-19
