Abstract

The Batang Arau River in Padang City exhibits contrasting environmental conditions between its upstream and downstream segments. The upstream–midstream areas still maintain good water quality with positive carrying capacity, while the downstream segment has exceeded its natural assimilation limit due to increasing pollutant loads originating from domestic and community activities. This study aims to analyze water quality, calculate carrying capacity, and model the relationship between community behavior and the river’s assimilation capacity using a system dynamics approach. The modeling results indicate a continuous decline in carrying capacity driven by population growth and waste generation, illustrating that human behavior has a direct impact on the ecological balance of the river. Therefore, sustaining the ecological function of the Batang Arau River requires integrated pollution control policies, community-based waste management, and continuous environmental education to enhance public awareness and ensure the long-term sustainability of the river ecosystem.

Abstract

This study aims to: (1) determine the level of flood vulnerability and the affected areas in Bengkalis Regency, Riau Province; and (2) analyze both the current and necessary flood disaster mitigation efforts in the region. A quantitative descriptive method was employed, utilizing a Change Detection approach to identify flood-inundated areas, and Interpretative Structural Modeling (ISM) as a decision-support tool for mitigation planning. The results indicate that flood vulnerability is primarily influenced by low slope gradients (0–8%), which facilitate rainwater accumulation, and high annual rainfall (>3000 mm), which accelerates surface runoff. The extent of affected areas includes 2,792.19 hectares for biennial floods, 10,995.18 hectares for five-year floods, and 67,825.93 hectares for floods occurring every ten to twenty years. Biennial floods impact 248 houses in villages such as Sekodi, Kelemantan, and Teluk Pambang. Five-year floods affect 681 houses in villages including Ketam Putih, Batu Panjang, and Muara Basung. Meanwhile, ten- to twenty-year floods affect 3,473 houses in areas like Sungai Alam, Pematang Duku, and Petani. ISM analysis reveals that the top-priority mitigation strategy lies at level 5, specifically element A6, which concerns the disaster planning conducted by the Regional Disaster Management Agency (BPBD). These findings underscore the urgency of structured and adaptive disaster planning to minimize flood risks and impacts in Bengkalis Regency.

Abstract

Oil palm plantations are currently experiencing quite rapid growth; this has resulted in a large number of oil palm fruit processing industriespalm oil (crude palm oil) and palm kernel (palm kernel). The more oil palm fruit that is processed, the more liquid waste it produces. Liquid waste generated during the production process can harm the environment because of the high organic matter contained therein. The purpose of this study was to analyze the management of palm oil industrial wastewater at PT Citra Putra Kebun Asri.The method used in this study is an exploratory method and the collection and testing of data is done by graph sampling. The results of the analysis contained in the palm oil industrial wastewater, namely the pH content ranges from 4-8.5. The content of BOD and COD in the first pool had quite high levels, this was due to (human error) during testing, factory measuring instruments that had not been calibrated and inaccurate sampling by factory staff. While the BOD and COD in the application pond have values ​​that are in accordance with the liquid waste quality standards with BOD values ​​below 100 mh/L and COD values ​​below 250 mg/L

Abstract

Stunting, or stunted growth, is a serious global public health problem. The aim of this research is to investigate the dynamics of co-occurrence, trends and saturation of keywords in spatial studies related to stunting using the literature review method. This research uses bibliometric analysis with the help of Web Lens.org, Openrefine, and VOSviewer for data collection and analysis. VOSviewer can display bibliometric mapping in three different visualizations, including network visualization, overlay visualization, and density visualization. The findings of this research reveal seven topic clusters related to the subject of this research, with network visualization results showing that research with the keywords 'spatial' and 'stunting' is still relatively limited. The overlay visualization results show that this research trend only emerged at the beginning of 2020 and has not yet reached saturation point. In conclusion, there is still a lot of room for further research in this area, making spatial stunting an interesting and potentially useful area for further exploration.

Abstract

The decline in water quality is caused by pollution pressure due to low environmental sanitation efforts. Water quality can be determined by carrying out certain tests on the water. This research was conducted on the Batang Ombilin River, Sawahlunto City. This research was conducted in October 2022. This research used survey methods and laboratory test methods. Activities carried out using the survey method are in the form of interviews related to research. Next, laboratory test methods are used to analyze water quality. Interview activities were carried out with people living around the Batang Ombilin River. Respondents were determined using random sampling. Samples were taken of 2 liters of water and carried using plastic bottles. The parameters used to see water quality are TDS, TSS, pH, DO, BOD and COD. Based on research that has been carried out, the results show that 65.25% of respondents stated that the existing water is suitable for consumption but must be filtered and purified first before cooking. Meanwhile, 30.75% of respondents stated that it was not suitable for consumption because the water was cloudy, dirty and smelly. Furthermore, in the water quality analysis, the average value of the TDS parameter was obtained with an average value of 108. TSS obtained an average value of 29.1. The pH got an average value of 8.1. DO got an average score of 7.3. BOD got an average score of 1.4 and COD got an average score of 15.2. From the results of tests carried out at 3 different points, an average value was obtained below the established class 2 water quality standards

Abstract

Indonesia is one of the countries that has the largest area of ​​natural forest in the world and is often referred to as one of the world's lungs which contributes oxygen for the survival of living things. Even though forests have many benefits, if the benefits from forests are not managed properly and correctly, they can have negative impacts and can lead to disasters and conflicts, apart from that, there is a fairly high level of deforestation and poverty is still often found in communities in and around forests. made various parties including the Ministry of Environment and Forestry try to encourage community empowerment programs. One of these community empowerment programs is Social Forestry. This type of research uses a quantitative approach with a descriptive design in the form of a case study. The population used in this research is the area and managers of LPHN Salimbutan Lubuk Alung, Padang Pariaman Regency. The samples from this research are all areas managed by LPHN Lintasutan Lubuk Alung. The instruments used in this research were observations and questionnaires. The results of this research show that in 2017 the level of deforestation at the Salimbutan LPHN increased by 9.7 Ha, then in 2018 it decreased by 2.6 Ha, in 2019 by 0.8 Ha, in 2020 by 1.4 Ha, in 2021 with a total of 0.8 Ha, and then in 2022 it will increase again with a total of 4.7 Ha. Meanwhile, community income before the training and assistance was still relatively low with a percentage of 11.16%.

Abstract

In Malaysia, flash floods or major floods often occur in the capital city of Kuala Lumpur, flooding is a natural phenomenon that occurs when the volume of water flowing in rivers, lakes, or other bodies of water overflows onto land. The purpose of this study is to determine the level of flood vulnerability and determine flood mitigation strategies. This research is descriptive quantitative, which describes the phenomenon of flood disasters through mapping results. To produce a map of flood-prone areas, mapping was carried out using ArcGIS with a scoring method to see flood hazard vulnerability. The results of the flood vulnerability mapping study in Kuala Lumpur show critical conditions with almost 90% of the total area of 27.195.47 hectares categorized as vulnerable to very vulnerable to flooding. Analysis using the Analytic Hierarchy Process (AHP) method identified three priority mitigation strategies, namely Regulation (57.7%) as the highest priority which includes policy enforcement and implementation of MSMA, followed by Education (25.8%) to increase public awareness and preparedness, and Conservation (16.5%) through ecological rehabilitation and green infrastructure. The integration of these three strategies is necessary to create a comprehensive and sustainable flood mitigation framework, taking into account the high urbanization and climate change that continue to increase flood risks in the Kuala Lumpur metropolitan area.

Abstract

Household organic waste management represents a critical environmental challenge requiring practical and sustainable solutions, particularly in densely populated urban areas of developing countries. Biopore Infiltration Holes (BIH) constitute an environmentally friendly technology that can be directly implemented at the household level to accelerate organic waste decomposition while simultaneously enhancing soil infiltration capacity. This study aims to conduct a multidimensional sustainability assessment of BIH implementation for household organic waste management in Kampung Sanitasi, Tabiang Banda Gadang Subdistrict. The research employed a descriptive qualitative approach with sustainability analysis using a modified RAPFISH (Rapid Appraisal for Fisheries) method adapted to organic waste management contexts. Data were collected through structured interviews (n=30 households), field observations, questionnaires, and documentation. Each dimension was evaluated based on multiple attributes scored and analyzed using Multi-Dimensional Scaling (MDS) to generate sustainability indices, supported by Monte Carlo simulation and leverage analysis for reliability testing. The multidimensional sustainability analysis revealed varying levels across dimensions: effectiveness (61.69 - moderately sustainable), efficiency (56.91 - moderately sustainable), and practicality (80.52 - highly sustainable), with an overall sustainability score of 66.37 (moderately sustainable). Community participation and environmental literacy emerged as critical determinants of successful implementation. BIH technology demonstrates strong potential as a sustainable household organic waste management strategy, particularly due to its high practicality. The RAPFISH-based multidimensional assessment provides a robust framework for evaluating and improving community-based environmental technologies.
