Abstract

Cibodas Village, Pasir Jambu District, Bandung Regency is in the upstream area in the Ciwidey sub-watershed area, which is one of the sub-watersheds in the Citarum watershed.  The principle of Eco drainage as a way in water conservation needs to be applied in this region. Community Service activities in the context of community empowerment in the planning and implementation of Eco drainage began with providing a basic understanding and technical properties of Eco drainage infrastructure and continued with piloting Eco drainage design for village governments, and community mobilizers to be able to implement Eco drainage in managing rainwater runoff. The community empowerment method consists of 3 stages, namely the coordination stage with partners and field surveys, preparation, and implementation of PkM. Coordination activities as a collaborative in building partnerships can run well. This can be seen from the full support of the Village Head, BumDes Chairperson, and the participation of village government officials both through initial coordination, field surveys to community involvement in planning a pilot infiltration structure design as an application of Eco drainage in the courtyard of the RW-04 office which also functions as a Pos Posyandu. Increased capacity and being self-sufficient in the application of Eco drainage are expected to be sustainable to all village communities. It expected the result will provide a multiplier effect in transforming Cibodas Village into an Ecovillage Village for the sustainability of the Citarum River as a water resource, since enable to play a role in the management of the Ciwidey watershed and the Citarum watershed in general. Abstract in BahasaDesa Cibodas, Kecamatan Pasir Jambu, Kabupaten Bandung berada di daerah hulu di wilayah sub-DAS Ciwidey, yang merupakan salah satu subDAS yang berada dalam DAS Citarum. Pengelolaan sumber daya air dengan menerapkan prinsip ekodrainase sebagai salah satu cara dalam konservasi air perlu diterapkan di wilayah ini. Metode pemberdayaan masyarakat terdiri dari 3 tahap yaitu tahap koordinasi bersama mitra dan survey lapangan, persiapan dan pelaksanaan PkM. Kegiatan koordinasi sebagai upaya kolaboratif dalam membangun kemitraan dapat berjalan dengan baik. Hal ini dapat terlihat dari dukungan penuh dari Kepala Desa, Ketua BUMDes serta partisipasi aparat pemerintah desa baik melalui koordinasi awal, survey lapangan hingga pelibatan masyarakat dalam merencanakan percontohan desain bangunan resapan sebagai penerapan ekodrainase di halaman Kantor RW04 yang sekaligus juga berfungsi sebagai Pos Posyandu. Kegiatan Pengabdian kepada Masyarakat (PkM) bertujuan untuk meningktkan kapasitas masyarakat dalam perencanaan dan implementasi ekodrainase dimulai dengan memberikan pemahaman dasar serta sifat teknis infratruktur ekodrainase dan dilanjutkan dengan percontohan desain ekodrainase bagi pemerintah desa, dan penggerak masyarakat agar dapat menerapkan ekodrainase dalam mengelola limpasan air hujan. Pemberdayaan serta kemandirian dalam penerapan ekodrinase diharapkan dapat berkelanjutan kepada seluruh masyarakat desa, sehingga mampu memberikan multiplier efek dalam mewujudkan Desa Cibodas menjadi Desa Ecovillage, sehingga dapat berperan dalam pengelolaan DAS Ciwidey pada khususnya dan DAS Citarum pada umumnya, untuk keberlanjutan sumber daya air Sungai Citarum.

Abstract

Groundwater in DKI Jakarta is subject to microbiological contamination. Approximately 32% of the population in DKI Jakarta relies on groundwater as an alternative source of clean water, highlighting the urgent need to address and prevent contamination. This study aims to investigate the effect of the separation distance between septic tanks and wells on the levels of Total coliform (TC), Escherichia coli (EC), and organic parameter contamination in shallow groundwater. Groundwater quality data, including TC, EC, and organic parameters from 265 monitoring points in DKI Jakarta, was obtained from the Jakarta Environment Agency in 2022. A quantitative descriptive approach, incorporating spatial mapping of bacterial and organic contamination using Geographic Information System (GIS) tools, was employed. MANOVA analysis using SPSS 26 was conducted to determine the relationship between septic tank distances and shallow water contamination levels. Results indicate that the separation distance between septic tanks and wells significantly influences TC and EC contamination in Jakarta Pusat, Jakarta Timur, and Jakarta Barat. Organic contamination, however, is significantly affected only in Jakarta Pusat and Jakarta Timur. In contrast, Jakarta Utara was identified as the most contaminated region, with 84% of groundwater samples showing TC contamination, 55% exhibiting Escherichia coli (EC) contamination, and 69% affected by organic pollution. However, these contaminations were not proven to be influenced by the proximity of septic tanks. This is likely due to the area's coastal location, where hydrogeological conditions and diverse pollution sources play a more significant role in groundwater contamination. Improvements in sanitation infrastructure could significantly enhance groundwater quality, particularly in highly vulnerable areas such as Jakarta Utara.

Abstract

Converting land functions from vacant land to build area could be increased surface water flow and flood. The emergence of slum settlements and land conversion along the riverbanks mark changes in the Cikapundung watershed. The objectives of this study were to investigate the relationship between land use change and the hydrology of the Cikapundung watershed, as well as to offer land use scenarios for reducing surface water flow. The Soil and Water Assessment Tool (SWAT) used to assess the impacts of land use changes. It consists of several stages, namely watershed delineation, formation of a Hydrological Response Unit (HRU), climate data input, running the model, calibration, and validation. The SWAT model can predict the discharge flow with Coefficient of Determination (R2) and Nash-Sutcliffe Efficiency (NSE) values of 0.80 and 0.05 for the calibration phase, and R2 and NSE values of 0.79 and -0.62 for the validation process. Based on SWAT simulation results, the water balance depicts the hydrological analysis of the Cikapundung Sub-watershed, which includes rainfall of 1,518.4 mm/year, surface runoff of 542.7 mm/year, lateral flow of 265.9 mm/year, and base flow of 117,78 mm/year.  The soil and water conservation (SWC) techniques such as reforestation in sub-basin 1, agroforestry in sub-basin 2 and 3, and infiltration wells in sub-basin 4, should be the effective strategy for reducing runoff in the Cikapundung sub-watershed. This scenario has the potential to reduce surface flow by 50.2 percent while increasing lateral flow by 42.5 percent and base flow by 114.3 percent.

Abstract

Smart Watershed Management (SWM) merupakan pendekatan inovatif dalam pengelolaan daerah aliran sungai (DAS) yang mengintegrasikan teknologi modern, perencanaan strategis, dan partisipasi multipihak. Studi ini merupakan tinjauan literatur sistematik terhadap berbagai publikasi ilmiah yang membahas strategi dan teknologi dalam SWM selama dekade terakhir. Fokus utama kajian mencakup penggunaan model hidrologi (seperti SWAT dan DML-PMA), pendekatan Total Maximum Daily Load (TMDL), serta perencanaan partisipatif berbasis SWOT dan PESTEL. Hasil kajian menunjukkan bahwa keberhasilan SWM bergantung pada integrasi antara pemanfaatan data spasial, penguatan kapasitas kelembagaan, dan keterlibatan masyarakat lokal. Selain itu, SWM terbukti meningkatkan efektivitas konservasi tanah dan air, menurunkan beban pencemar, serta memperkuat ketahanan sosial-ekologis DAS, khususnya di wilayah dengan tekanan lingkungan tinggi. Temuan ini diharapkan dapat menjadi referensi bagi pengambil kebijakan dan peneliti dalam merancang pengelolaan DAS yang adaptif dan berkelanjutan

Abstract

Dalam sistem distribusi air minum, fluktuasi pemakaian air tiap jam dalam 1 hari digunakan untuk perencanaan reservoir dan operasional pompa distribusi, sedangkan kebutuhan air jam puncak digunakan dalam perencanaan dimensi pipa distribusi. Penelitian ini bertujuan untuk meningkatkan pemahaman pola konsumsi air minum sehingga dapat memperbaiki operasional sistem distribusi. Pada studi ini dilakukan analisis pola konsumsi di 2 reservoir distribusi Kabupaten Purworejo dengan pengumpulan data konsumsi air tiap jam selama 7 hari di meter induk reservoir. Pola konsumsi di Kutoarjo menunjukkan adanya 2 puncak pemakaian dengan faktor jam puncak 1,27, sedangkan pola konsumsi di Tuk Songo berkisar pada konsumsi rata-rata dengan faktor jam puncak 1,07. Penyimpanan air di Reservoir Kutoarjo adalah 6,14% terhadap konsumsi harian atau 182,3 m3 terhadap volume aktual 850 m3, sedangkan Reservoir Tuk Songo hanya menyimpan 0,56% atau 29,2 m3 terhadap volume aktual 400 m3. Tidak terjadi penyimpanan air di reservoir. Diperlukan penelitian lanjut dan data yang lebih luas untuk mendapatkan pemahaman lebih baik mengenai pola konsumsi air agar diperoleh perencanaan pengelolaan operasional serta pengembangan jaringan pipa distribusi yang efektif, sehingga dapat meningkatkan pelayanan kepada pelanggan.

Abstract

Urban activities and runoff deteriorated the river water. Aim: This study aims to determine the primary contamination and mapping river's water quality variation in Greater Jakarta. Methodology and Results: Multivariate analysis was employed by Factor Analysis and Cluster Analysis (FA and CA) using the 12 parameters of the water quality dataset from 76 sampling stations in 19 rivers in the Greater Jakarta Region, Indonesia, between 2014 and 2015. The FA result showed that almost 66.6% of the total variance in water quality data was associated with four significant variators of which 36.12% identified the main parameters BOD, COD, TP, ammonia, nitrate, and detergent. The cluster analysis grouped the sampling locations into 3 (three) clusters to indicate the spatial classifications of river water. Cluster 1 indicates pollutants from the residential area, Cluster 2 from residential and commercial areas, while Cluster 3 is majorly pollutants from industrial areas. Conclusion, significance, and impact study: The results showed the conductivity and TDS concentrations in cluster 3 are higher than the others since most of the sampling points are located near an industrial area or downstream close to the estuary. The mapping gave a better understanding of the river water quality characteristic spatially and could assist local governments in prioritizing river pollution management.

Abstract

The United Nations Statistical Commission agreed in March 2020 to start using the Degree of Urbanisation as a method to delineate cities, urban, and rural areas to enable international statistical comparisons. The decision consequently promotes countries to change or align their classification and/or methods of urbanisation delineation. This is expected to increase the number of studies with “degree of urbanisation” or “urban classification” keywords around the world in line with the implementation of the method. Aim: This study aims to determine the research trends on the degree of urbanisation in the Scopus database from the year 2013 to 2022. Methodology and results: The bibliometric method was applied through the VOSviewer software (version 1.6.18. Leiden University, Leiden, Netherlands) for the analysis. The findings showed that the topics related to the degree of urbanization are underrepresented in terms of the number of publications and contributing nations though the trend in the number of articles published in the Scopus database has annually increased from 2017-2021. Conclusion, significance and impact study: This implies there is a lot of potential regarding the publication of studies on the concept of “degree of urbanization”

Abstract

The increase in the amount of groundwater withdrawal will inevitably pose a threat of seawater intrusion. The purpose of this research was to identify the distribution of shallow groundwater salinity in North Jakarta, West Jakarta and Central Jakarta and to develop a regional model of shallow groundwater salinity distribution. The data used in this study was that of the groundwater quality monitoring, obtained from the Regional Environment Status Book (SLHD), published by The Environment office of Greater Jakarta released in 2022, involving a total of 121 sample points in North Jakarta, West Jakarta, and Central Jakarta. The primary data was taken at 6 (six) sampling locations for model validation purposes. The study began with data grouping, using the Hierarchical Cluster Analysis (HCA) method. The results of identifying the highest distribution of salinity are in cluster 3 (three). A model was subsequently developed, after removing the outliers, with multiple linear analysis methods using the variable the distance from the coastline (X1), well depth (X2) and hardness (X3), to determine the influence of EC, TDS and salinity distribution in shallow groundwater. The results obtained are as follows; EC Models: YEC3 = -1.879+ (1.19.X1) + (5.08.X3). TDS models: YTDS3 = -2.211.30 + (0.81.X1) + (101.41.X2) + (4.07.X3). Salinity models: Ysalinity3 = -0.07+ (6.75×10-5.X1) + (2.4×10-4.X3). Model verification results for R2EC3 = 0.70; R2TDS3 = 0.92; R2salinity3 = 0.88. Validation results produce 21.14% for EC, 8.21% for TDS, and 22.87% for Salinity. This needs further research by increasing the number of primary samples.

Abstract

FLW merupakan ancaman serius terhadap ketahanan pangan serta perekonomian dunia. SDG 12.3 adalah konsumsi dan produksi yang bertanggung jawab yaitu menargetkan pengurangan FLW per kapita sampai separuhnya pada 2030. Timbulan sampah Indonesia 17 juta ton/tahun, hampir 70% merupakan sampah organik bersumber 38,3% dari rumah tangga dan jenis sampah terbanyak 42,4% adalah sisa makanan. Sekitar 44% limbah makanan berkontribusi terhadap Tempat Pemrosesan Akhir (TPA) di Indonesia. Metode PkM yang digunakan adalah penyuluhan pemilahan FLW dan pelatihan budidaya maggot menggunakan larva Black Soldier Fly (BSF), untuk mendaur ulang dan mengolah sampah organik. Masyarakat sangat antusias karena Tim PkM FALTL Universitas Trisakti menyiapkan insektarium sederhana agar budidaya maggot dapat langsung diterapkan. Peran masyarakat dalam mengurangi timbulan food waste di rumah tangga sangat penting dan signifikan. Hal ini juga sangat signifikan dalam penurunan gas rumah kaca (GRK) jika dibandingkan dengan pengurangan yang sama di food waste katering, restoran dan hotel, serta food loss pasca panen dan produksi. Kemampuan masyarakat dalam membudidayakan BSF penghasil maggot dan kasgot sebagai media pemrosesan sampah organik FLW perlu didukung dengan pelatihan dan penerapan prosedur secara benar agar tidak menyebabkan masalah lingkungan dan kesehatan baru.

Abstract

The Ciwidey sub-watershed serves as a buffer zone to meet the raw water needs of Bandung Regency. This study aims to assess the hydrological impacts of soil and water conservation techniques and evaluate the combined effects under extreme rainfall on runoff and baseflow dynamics. The Soil and Water Assessment Tool (SWAT) hydrological model was employed to predict flow discharge in the Ciwidey sub-watershed. The methodology included collecting hydrological, climate, and land-use data, delineating watersheds, forming Hydrological Response Units (HRUs), and conducting model calibration, validation, and simulation of a surface runoff. The spatial pattern of the Bandung Regency Regional Spatial Plan (RTRW) for 2016–2036 resulted model simulations predicted a surface runoff of 1,084.36 mm/year under extreme rainfall. The watershed conservation program demonstrates strong implementation of agroforestry and reforestation throughout the watershed region, with 42,313 hectares currently under management with 21 individual conservation projects in 9 districts. The conservation planning program consists of implementation Agroforestry (52.6%), reforestation (39.6%) and 7,8% infiltration well, with Pasir Jambu District and Subbasin 6 emerging as focus area of comprehensive conservation. The study demonstrates that integrating soil and water conservation is crucial for sustainable water resource management and flood risk reduction in rapidly developing regions.
