Abstract

Rapid urbanization and climate variability have degraded water quality and reduced the resilience of urban watershed. This study proposes a climate-responsive conceptual framework for assessing Water Ecological Carrying Capacity (WECC) in urban environments. The framework integrates hydro – climatic indicators, urban – climatic dynamics, and adaptive policy interventions, structured within the Driver–Pressure–State–Impact–Response (DPSIR) model. It is designed to evaluate the dynamic interactions between urban growth, climate variability, and freshwater ecosystem thresholds. A systematic review of 14 studies from Asia and beyond provides empirical support for the framework. Indicators such as streamflow variability, urban land use, water temperature, and governance capacity are categorized within the DPSIR components to illustrate the multifaceted nature of WECC. The study highlights how hydro – climatic and socio – economic stressors interact to influence the vulnerability and resilience of water ecosystems. Figures and tables within the paper visualize these interactions and simulate feedback loops under various environmental and policy scenarios. While the model presents a comprehensive and adaptable framework, it is based on secondary data and lacks validation through localized, real-time application. Nevertheless, it serves as a strategic tool for anticipating and addressing urban water sustainability challenges. It encourages the use of integrated, climate – informed planning approaches and provides a foundation for future research and policy in climate – sensitive regions. This study underscores the importance of evaluating WECC not as a static measure but as a dynamic function shaped by ecological, social, and climatic processes.

Abstract

Damage to the ecosystem there will cause problems for the city. The factors causing the damage to the lake in Depok City are changes in land use in the catchment area, sedimentation, pollution and eutrophication resulting in reduced aesthetic value. Basically, this lake ecosystem can be turned into a tourist destination. Situ Pangarengan, which is located in Cisalak Village, Sukma Jaya District, Depok City, initially has an area of about 10.00 Ha, but now it is 8.00 Ha and shrinks in the dry season to 6.70 Ha. Therefore, saving this ecosystem needs to be done by conducting outreach to the people who live around it. The purpose of this activity is to provide counseling on management by implementing conservation and structuring the landscape along Situ Pangarengan. The activity was carried out on August 18, 2022, attended by 40 people. The PKM method is carried out with counseling in the form of lectures, discussions. The training atmosphere is designed to be interactive so that participants can more easily understand with case examples in the field. The results of this PkM activity participants gain knowledge about the benefits of managing and conserving the Situ Pangarengan ecosystem properly; participants get information about the landscape design for the lake bank; participants get a forum to exchange opinions and provide input regarding the management of the Situ Pangarengan ecosystem and the necessary communication occurs between extension workers and participants for the preparation of further action plans

Abstract

Kurangnya pemahaman masyarakat mengenai manfaat dari teknologi rainwater harvesting ini menimbulkan berbagai macam permasalahan diantaranya yaitu belum memahami konsep Eko-Masjid dalam upaya menjaga keberlanjutan lingkungan. Tujuan pelaksanaan kegiatan ini yaitu; melakukan penyuluhan tentang konsep eco-masjid, melakukan pelatihan pemanfaatan air hujan dengan teknik rain harvesting, melakukan pelatihan pengurangan debit air untuk wudhu dan pengelolaan air bekas wudhu, membangun sumur resapan, membangun kolam penampung air bekas wudhu, dan menata lanskap disekitar masjid. Metode yang digunakan yaitu penyuluhan, pelatihan dan pembuatan saran contoh di Masjid Hidayaturrahman. Hasil yang didapat dalam PKM ini yaitu masyarakat menjadi lebih mengetahui dan memahami mengenai rainwater harvesting, sumur resapan, pengelolaan air wudhu dan konsep eco-masjid yang sudah diterapkan. Kesimpulan yang didapat yaitu kegiatan KKM dengan waktu yang singkat ini telah terlaksana dengan hasil memuaskan dan sangat bermanfaat dalam konservasi air.

Abstract

Industrial waste that contains heavy metal can cause environmental problem because of its toxicity, persistency and accumulation level in the environment. Biosorption process is highly influenced by temperature, pH, light, contact time, and ratio of surface area. Microalgae which possess two functional groups that are able to react on metal ion in a solution can be exploited to overcome environmental pollution due to heavy metal compound. Closed cultivation system in a photobioreactor is utilized to overcome contamination and evaporation problems on open pond system. Heavy metal analysis is conducted by utilizing Atomic Absorption Spectroscopy (AAS), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscope (SEM). This article provides information on biosorption as alternative technology to overcome heavy metal in water areas with no side effects on the environment with advantages of the absence of secondary pollutants, high level of efficiency, and relatively economic compared to physic-chemical method heavy metal removal methods

Abstract

Aim: The aims of this research is to determine the ability of an indigenous microbial consortium to degrade Low Density Polyethylene plastics. The plastic was cut mechanically into 1 x 1 cm2 pieces because the smaller the size of the plastic, the larger the surface area. The samples are input in an Erlenmeyer flask containing indigenous microbial consortium and fungi (20% v/v) and Stone Mineral Salt solution media (80% v/v). This research lasted 10 days with a pH of 7 controlled and temperature variations of 25, 30, 35°C. As preliminary research, the sensitivity test seeks to demonstrate that the indigenous microbial consortium and fungi are resistant or insensitive to LDPE. The degradation of LDPE plastic was analyzed using gravimetric methods, Fourier Transform Infrared, and a scanning electron microscope. Methodology and results: According to the results of gravimetric and FTIR analysis, the highest removal value was at a temperature variation of 30°C. The gravimetric analysis revealed that the weight loss in LDPE plastic was 0.0082 gr to 0,0074 gr or 9.76 %, while the FTIR analysis revealed that the intensity removal result was 6,27 %. Conclusion, significance, and impact of study: Scanning Electron Microscope (SEM) analysis revealed morphological changes on the surface of LDPE plastic samples, confirming these findings. Several factors influence the changes that occur in this study's LDPE plastic samples.

Abstract

Kelurahan Cisalak, Kota Depok memiliki luas 2,68 km2, jumlah penduduk 17.264 orang dengan kepadatan 6.642 orang/km2. Masyarakat belum mengolah air limbah domestik greywater namun telah memiliki septic tank untuk mengolahan air limbah black water. Guna mengurangi pencemaran perlu dilakukan pengolahan air limbah dengan menggunakan lahan basah buatan. Metode PkM adalah penyuluhan, pelatihan, FGD dan pembangunan lahan basah buatan. Peserta sebanyak 45 orang yang terdiri dari perangkat kelurahan, para ketua RW, ketua RT, ketua PKK kelurahan, RW dan pokja bidang lingkungan, ketua posyandu dan karang taruna. Pembangunan lahan basah buatan dilakukan di RW terpilih yaitu di RW 03. Pengerjaan IPAL dan taman dilakukan secara bergotong royong oleh masyarakat dibawah koordinasi karang taruna. Kegiatan PKM ini memberikan pengetahuan baru yang sangat berguna untuk penerapan konsep pengelolaan air limbah greywater. Dampak sosial yang didapat adalah perubahan perilaku dalam memelihara lingkungan.
