"Pengelolaan sumber daya air terpadu merupakan kegiatan yang sangat penting guna mendapatkan jaminan ketersediaan air yang mencakup perspektif antar sektor, kesenjangan kebutuhan mendatang, dan ketersediaan saat ini serta berorientasi pada tiga pertimbangan utama yaitu sosial, ekonomi, dan lingkungan. Dalam dekade terakhir banyak negara di Asia telah menerapkan kebijakan nasional dalam pengelolaan air dengan sistem pengelolaan sumber daya air pada wilayah sungai walaupun penerapannya masih dalam tahap permulaan. Pengelolaan sumber daya air terpadu di wilayah sungai dilaksanakan dengan baik oleh organisasi pengelola sungai dengan memfasilitasi dan/atau melaksanakan berbagai proses pembangunan dan pengelolaan. Di Asia berbagai pengelola sungai baik kecil maupun besar membantu pemerintah dan pemilik kepentingan dalam merealisasikan pengelolaan air terpadu. Beberapa pengelola sungai merupakan organisasi pemerintah. Namun, dalam beberapa kasus untuk memberikan keleluasaan serta otonomi, baik dalam pengelolaan, pengembangan, maupun keuangan digunakan sistem perusahaan atau semi-perusahaan. Tulisan ini mengkaji perbedaan antara tiga tipe sistem pengelolaan wilayah sungai yaitu: komite, publik/pemerintah, dan korporasi. Dengan demikian, dapat ditentukan tipe/jenis pengelolaan yang paling sesuai untuk diterapkan di suatu wilayah sungai."

"Pertambahan penduduk merupakan fenomena yang tidak dapat dihindarkan. Di Indonesia sendiri terdapat kurang lebih 271 juta jiwa dan 56% diantaranya tinggal di pulau Jawa (Badan Pusat Statistik, 2014). Hal ini menyebabkan intensitas aktivitas antropogenik meningkat, sehingga mengakibatkan limpasan limbah yang besar yang dibuang ke sistem sungai. Pencemaran ini dapat ditemukan baik di kolom air maupun di sedimen yang telah terakumulasi dalam jangka waktu yang lama. Penelitian ini bertujuan untuk mengidentifikasi polutan di sungai-sungai perkotaan yang berada di wilayah Jabodetabek, menganalisis hubungan antara penggunaan lahan dan kualitas sungai dan memberikan rekomendasi mengenai opsi remediasi yang akan dilaksanakan. Pengambilan data dilakukan dengan mengambil sampel yang berada di hulu Sungai Ciliwung dan beberapa titik yang tersebar di wilayah Jabodetabek. Pengujian yang dilakukan meliputi parameter organik dan unsur logam berat. Parameter organik berupa DO, TN, TP, TOC, pH, suhu dan TSS. Hasil analisis tata guna lahan dan jarak garis lurus setiap pengambilan sampel ke bagian hilir Sungai Ciliwung dikaitkan dengan data yang telah diperoleh dari pengujian sampel. Analisis logam berat dilakukan dengan menghitung nilai indeks geoakumulasi, dimana komposisi logam berat pada setiap titik pengambilan sampel dibandingkan dengan nilai latar belakang atau hulu Sungai Ciliwung. Ditemukan adanya unsur-unsur seperti Mn, Cr, Ni, Eu, Mo, Yb dan Re yang menjadi beban pencemaran terbesar di lokasi tersebut. Setelah melalui perhitungan indeks geoakumulasi, ditemukan bahwa Sungai Mookervart tergolong pencemaran ekstrim. Sehingga Sungai Mookervart menjadi pilihan utama dalam melakukan pemulihan melalui metode remediasi. Metode remediasi yang disarankan adalah pengerukan atau dredging karena geometri Sungai Mookervart cenderung kecil. Secara teknis, pengerukan Sungai Mookervart sepanjang 2,16 km akan menelan biaya sekitar 8 miliar rupiah dan membutuhkan waktu 10 hari untuk menyelesaikan perbaikan.

Population growth is an unavoidable phenomenon. In Indonesia alone there are approximately 271 million people and 56% of them live on the island of Java (Central Bureau of Statistics, 2014). This causes the intensity of anthropogenic activity to increase, resulting in large waste runoff being discharged into the river system. This pollution can be found both in the water column and in sediments that have accumulated over a long period of time. This study aims to identify pollutants in urban rivers located in the Greater Jakarta area, analyze the relationship between land use and river quality and provide recommendations on remediation options to be implemented. Data collection was carried out by taking samples in the upper reaches of the Ciliwung River and several points scattered in the Greater Jakarta area. The tests carried out include organic parameters and heavy metal elements. Organic parameters in the form of DO, TN, TP, TOC, pH, temperature and TSS. The results of the land use analysis and the straight line distance of each sampling to the lower reaches of the Ciliwung River are associated with the data that has been obtained from sample testing. Heavy metal analysis was carried out by calculating the geoaccumulation index value, where the composition of heavy metals at each sampling point was compared with the background value or the upstream of the Ciliwung River. It was found that the presence of elements such as Mn, Cr, Ni, Eu, Mo, Yb and Re which became the biggest pollution burden at that location. After going through the calculation of the geoaccumulation index, it was found that the Mookervart River is classified as extreme pollution. So that the Mookervart River becomes the main choice in carrying out recovery through the remediation method. The recommended remediation method is dredging or dredging because the geometry of the Mookervart River tends to be small. Technically, dredging the 2.16 km Mookervart River would cost around IDR 8 billion and take 10 days to complete the repairs."

"Tujuan utama penelitian ini adalah membangun model peningkatan resiliensi sistem sosio-hidrologis melalui tata kelola air polisentrik yang mengintegrasikan resiliensi komunitas untuk menjamin keberlanjutan fungsi ekosistem sungai di Wilayah Sungai Citarum. Metode yang digunakan adalah formula matematis untuk menghitung vulnerability index dengan menggunakan data sekunder dari berbagai institusi pengelola Wilayah Sungai Citarum, yang selanjutnya disebut sebagai WS Citarum. Hasil perhitungan vulnerability index digunakan sebagai dasar penetapan status resiliensi sistem sosio-hidrologis WS Citarum. Selain itu digunakan pula permodelan statistik Structural Equation Modelling (SEM) dengan menggunakan perangkat lunak LISREL versi 8.7 untuk menetapkan resiliensi komunitas. Resiliensi komunitas dianalisis berdasarkan data primer hasil pengukuran modal sosial masyarakat (social capital) dan nilai, keyakinan, norma serta perilaku peduli lingkungan (values, beliefs, norms and pro-environmental behavior), individu anggota masyarakat di WS Citarum. Model konseptual upaya peningkatan resiliensi sistem sosio-hidrologis dibangun menggunakan permodelan system dynamics dengan perangkat lunak VensimPLE versi 9.3.0. Hasil penelitian menunjukkan bahwa vulnerability index (VI) di Wilayah Sungai Citarum adalah sebesar 1,80 pada Zona Citarum Hulu yang menunjukkan bahwa sistem sosio-hidrologis pada zona ini berada pada status rentan sedang (moderate vulnerability). Sedangkan pada Zona Citarum Tengah, nilai VI adalah 2,52 dan pada Zona Citarum Hilir adalah 2,06, yang menunjukkan bahwa sistem sosio-hidrologis pada kedua zona tersebut berada pada status sangat rentan (significant vulnerability). Kesimpulan penelitian ini adalah bahwa untuk mengatasi kerentanan sistem sosio-hidrologis di WS Citarum diperlukan implementasi model peningkatan resiliensi sistem sosio-hidrologis melalui intervensi tata kelola air polisentrik. Tata kelola air polisentrik yang didukung oleh aksi kolektif masyarakat dengan kekuatan modal sosial dan perilaku peduli lingkungan, sebagai wujud resiliensi komunitas, diharapkan dapat mencapai keberlanjutan fungsi ekosistem sungai di Wilayah Sungai Citarum.

The main objective of this research was to develop a model representing the resilience of the socio-hydrological system through polycentric water governance that integrates community resilience to ensure the sustainability of river ecosystem services in the Citarum River Basin. The method used in this study is a mathematical formula to calculate the vulnerability index using secondary data from various institutions managing the Citarum River Basin (CRB). The results of the vulnerability index calculations were used as the basis for determining the resilience of the CRB socio-hydrological system. Furthermore, statistical modeling of structural equation Modelling (SEM) using LISREL software version 8.7 is also used to assess community resilience. Community resilience was analyzed based on primary data from the results of measuring community social capital and the values, beliefs, norms, and pro-environmental behavior of individual community members in the Citarum River Basin. A conceptual model representing the resilience of the socio-hydrological system was built using system dynamics modeling with the VensimPLE software version 9.3.0. The results show that the vulnerability index (VI) in the Citarum River Basin is 1.80 in the upstream zone, indicating that the socio-hydrological system in this zone is moderately vulnerable. In the middle zone, the value of VI is 2.52 and in the downstream zone, it is 2.06, which indicates that the socio-hydrological system in the two zones is significantly vulnerable. This study concludes that to overcome the vulnerability of the socio-hydrological system in the Citarum River Basin, it is necessary to implement a model to increase the resilience of the socio-hydrological system through polycentric water governance interventions. Polycentric water governance supported by collective community action with the strength of social capital and pro-environmental behavior as a form of community resilience will achieve the sustainability of river ecosystem services in the Citarum River Basin.

"In 2011, massive flooding and inundation in the Chao Phraya River basin, in Thailand, causedserious damage to various activities for a prolonged period of time. Although snapshot images ofthe inundated area are available, detailed information including temporal changes of the inundatedareas and the relationship with meteorological and hydrological conditions are not welldocumented, particularly for the middle and upper sections of the basin. Therefore, we conductedan analysis using two types of satellite data, HJ-1A and Envisat, to better understand behavior ofthe large-scale inundation occurred in 2011, focusing on the middle section of the Chao PhrayaRiver basin. In the analysis, water surface in selected domains was extracted using the NDWI valuecalculated from HJ-1A data. The threshold value of the Envisat ASAR image was then adjusted sothat the inundated area estimated from Envisat gives the closest possible match with that estimatedfrom HJ-1A. Finally, the inundated area was estimated for the whole study domain based on thesame threshold value from the Envisat data. Results indicated that the inundated area began toextend along the Yom and Nan rivers in early August and continued to spread down to the NakhonSawan city area until October. A significant increase in inundated areas occurred between Sep. 2and Sep. l3, during which higher rainfall intensity was observed. Even after the water level inrivers receded below the bank-full elevation, large areas were left inundated along rivers,particularly over lowlying marsh and paddy fields. In addition, several areas located far fromrivers were also inundated, which was likely a consequence of water ponding in paddy fields."
