PREDICTION OF GROUNDWATER STORAGE IN CISADANE WATERSHED

Water is very important for human beings.Sources of fresh water that can be used are only 3% of the total water availability on earth, and 12% from that quantity are soureces of groundwater. Groundwater is one of the water resources that very important in sufficient human needs, such as domestic, agriculture or industry. Geoelectric is one of methods for groundwater investigation. The purposes of this research are to identify litholgy of soil layer, thickness of aquifer position on research location, determining hydraulic soil conductivity value and predict the groundwater reserve potential in Cisadane Watershed. This research was conducted in several steps, such as collected data and analysis data. The processed data was the secondary geoelectrical data with schlumberger method. Calculation of groundwater storage using geoelectric and Darcy’s law. Aquifer thickness layer obtained from the average content aquifer layer on research location, so it can represents the thickness of the aquifer. From the calculation result obtained groundwater reserve prediction amounted to 2.46 m3/second for unconfined aquifer and 8.64 m3/second for confined aquifer

Analisis Indeks Pencemaran Airtanah di DKI Jakarta dengan Interpolasi Spasial: Analysis of Groundwater Pollution Index in DKI Jakarta using Spatial Interpolation

Everyone needs water to his life and his activity. Groundwater pollution is one of the problems in Indonesia. The increasing number of the show an increase water needs. They were filled with groundwater needs. There has been decreasing groundwater that is occupied in quantity and quality. The research was done in Jakarta, consisting of 42 sub-district. Research takes into account the condition of the dry season. Uses index research quality of groundwater pollution. Monitoring parameter groundwater consisting of physics, chemical and biology paramater. The research consists of determining the pollution index in Jakarta, analysis of groundwater pollution, and predicted entanglement with an index pollution population density. The research uses spatial interpolation to determine locations. Pollution index calculation used calculation storet. The measurement results in the rate used in the analysis index groundwater pollution. The research results obtained index value has increased pollution are on the north and central of Jakarta. The research results obtained East Jakarta having the condition geology that porous. The value of the groundwater pollution index was in north Jakarta. The results of the study indicated by a map pollution index the quality of groundwater during three periods. Index pollution in Jakarta consisting of pollution until the same as the quality standard. Research shows the absence of correlation with the population with the pollution groundwater quality

Ecological assessment of different electrokinetic remediation strategies: a pilot scale study

The electrokinetic remediation method can function as a primary or secondary technology and can be applied in conjunction with other physical and biological methods, such as soil washing, phytoremediation, and bioremediation. Environmental impacts arising from the electrokinetic remediation process can be determined using life cycle assessment analysis (LCA) or other tools. This study compared the conventional electrokinetic remediation strategy with two hybrid strategies: electrokinetic-phytoremediation (EKR-Phyto) and electrokinetic-bioremediation (EKR-Bio). The environmental performance of the three strategies is then tested through LCA analysis. The database used was The Ecoinvent, and the freeware software used during the inventory stage was OpenLCA. The impact assessment stage was used in the Recipe I (2016) midpoints, Available Water Remaining (AWARE) midpoint, Intergovernmental Panel Climate Change (IPCC) midpoint (2003), UNEP Society of Environmental Toxicology (USEtox) midpoint, and cumulative energy demand midpoint. The significance of the analysis results was not obtained for the GWP parameter but for the freshwater eutrophication parameter. Among the three strategies, the EKR-Phyto strategy showed the highest significance in eutrophication but the lowest significance in land change. Substitution of chemical fertilizers into natural fertilizers in the EKR-Phyto strategy can be an opportunity for environmental sustainability. The highest impact for ecological analysis of the three strategies was EKR-Phyto in terms of GWP, the sum of primary energy, Acidification Potential (AP), and Photochemical Ozone Creation Potential (POCP)

Analisis Potensi Tempat Pemrosesan Akhir (TPA) di Kecamatan Marangkayu, Kabupaten Kutai Kartanegara: Potential Analysis Place of Final Processing Site in Marangkayu Sub-District, Kutai Kartanegara

Sampah padat perkotaan merupakan fenomena yang sulit dihindari pada daerah perkotaan. Setiap daerah dan kota memiliki permasalahan yang berbeda mengenahi penanganan dan pemrosesan sampah padat perkotaan. Semakin tinggi status suatu kota, maka akan semakin tinggi potensi menghasilkan sampah padat sehingga perlu adanya penyediaan Tempat pemrosesan Akhir (TPA). Daya tampung lahan menjadi permasalahan dalam penentuan tempat pemrosesan akhir. Kabupaten Kutai Kartanegara adalah salah satu kota yang diprediksi akan menjadi kandidat kota besar pada masa depan. Tujuan penelitian adalah untuk menganalisis potensi lahan yang akan digunakan pada Tempat Pemrosesan Akhir (TPA) berdasarkan aspek teknis dan lingkungan. Lokasi penelitian berada di Kecamatan Marangkayu, Kabupaten Kutai Kartanegara. Metode yang digunakan dalam penelitian adalah menggunakan survei lapangan kondisi eksisting berupa pengukuran elevasi kondisi eksisting dan penentuan lokasi berdasarkan SNI 19-3241-1994 tentang Tata Cara Pemilihan Lokasi TPA Sampah. Berdasarkan hasil penelitian dapat disimpulkan penentuan lokasi pemilihan TPA di Kecamatan Marangkayu, Kabupaten Kutai Kartanegara dari tiga lokasi. Pemilihan lokasi diutamakan berdasarkan hasil permodelan genangan air 0 sampai 10 m dan zona penyangga. Kesimpulan yang didapatkan berdasarkan penelitian ini dipilih lokasi kedua yang cocok sebagai lokasi TPA di Kecamatan Marangkayu

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
