“…However, because gray water contains fats, detergents, soaps, organic materials, salts and even pathogens, improper operation may cause the proliferation of various diseases and affect the health of individuals, animals and the environment [41]. In this context, RWHSs, which use clean and reliable sources of rain, have a major impact on reducing the volume of water and thereby reducing the risk of floods [42,43]. Nevertheless, the hydraulic performance of RWHSs is highly associated with the tank size, which may lead to a significant occupation of space and a negative social impact due to the poor aesthetics in the community.…”

Rainwater harvesting systems (RWHSs) have been accepted as a simple and effective approach to ease the worsening of urban water stress. However, in arid and semiarid regions, a comprehensive method for promoting domestic RWHSs in a large-scale water-saving scheme that incorporates water consumption reducing equipment (WCRE) and gray water reuse (GWR), has not been well developed. For this, based on the case study of Guilan Province, Iran, this study addressed the temporal-spatial complex of rainfall and proposed a GIS-simulation-based decision support system (DSS). Herein, two scenarios, i.e., the typical RWHS and the modified RWHS for arid areas, were tested; and the associated economic analysis was performed and compared with WCRE and GWR. Moreover, for larger-scale implementation, the multiple criteria decision making (MCDM) technique was further applied to address the social-environmental complexity of these water-saving methods. Guilan Province has thereby been classified into three priority levels, providing a straightforward understanding of how to promote the large-scale water-saving scheme. Compared with the traditional generalized method, sensitivity analysis verified that this DSS enhanced the information value. Hence, the DSS that provides more holistic and comprehensive support has been identified as a useful tool to ease the threat of urban water stress.

“…Skenario 2 (RTRW) menghasilkan nisbah sebesar 4,04 (sangat rendah) dan skenario 1 sebesar 5,71 (rendah). Sepehri et al (2018) menyebutkan bahwa faktor-faktor yang memengaruhi aliran sungai secara umum dapat dibagi 2, yaitu karakteristik hujan dan karakteristk DAS. Karakteristik hujan yang memengaruhi aliran sungai adalah jumlah, intensitas, lama hujan, dan distribusi hujan yang jatuh pada suatu DAS, sedangkan pengaruh karakteristik DAS ditentukan oleh ukuran, bentuk, orientasi, topografi, geologi, dan penggunaan lahan.…”

One of the priority watersheds to be managed in Indonesia is the Cisadane watershed due to the high degradation problems. The Cisadene watershed degradation could be indicated by a high river flow during rainy season, low baseflow in dry season, and high erosion and sedimentation. One of the main problems in the Cisadane watershed is a huge landcover changes in the Cisadane Hulu watershed that causes a decrease in water absorption region and a surface runoff. The study aimed to analyze landcover changes in the Cisadane Hulu Watershed during 2013-2018 and analyze the watershed conditions based on their hydrological characteristics. Analysis of landcover changes patterns was carried out by processing spatial data using GIS software. Analysis for hydrological characteristics was conducted by using SWAT modelling (Soil and Water Assessment Tool). The results showed that there were land cover changes during 2013-2018. The most significant landcover changes in the Cisadane Hulu watershed was residential area (455.95 ha). The result simulation scenario of the model SWAT showed scenario 2 was the best scenario for the management of the Cisadane Hulu watershed. The application of Soil and Water Conservation can decrease surface runoff by 32.1% and increase lateral flow by 8.89%. Therefore, it is expected that the results of this SWAT model simulation will be taken into consideration by the local government for the optimal management of the Cisadane Hulu watershed. Keywords: Cisadane watershed, land cover change, SWAT modelling

“…Alat PAH dapat dibangun atau diletakkan di atas permukaan tanah, di bawah permukaan tanah, atau di bawah bangunan, disesuaikan dengan ketersediaan lahan. 7 Alat PAH yang diletakkan di atas permukaan tanah mempunyai berbagai keunggulan, antara lain mudah dalam mengambil/ memanfaatkan airnya (pengalirannya dapat dengan metode gravitasi) dan mudah perawatannya. Volume penampung air hujan yang digunakan dalam sistem PAH harus disesuaikan dengan luas atap serta curah hujan setempat.…”

Flood disaster in Bima Town, West Nusa Tenggara Province, Indonesia at the end of 2016 affected 105,753 people. For the period of the disaster, water flooding whole area of the town. Universitas Gadjah Mada (UGM) represented by Faculty of Medicine, Public Health, and Nursing supported by the Faculty of Medicine Alumni Association (KAGAMADOK) sent two response teams to the disaster area with the aims to assess health status of the refugees and to create rainwater harvesting tool. There were two teams assigned to the flood management in Bima. First team assigned to establish database and health cluster information analysis, performed needs assessment at refugee camp and affected area, and sent the patient to emergency health service. Regarding to the first team assessment results, second team assigned to create rainwater harvesting tool. First UGM team discovered that communities experiencing high prevalence of dermatology disease, meanwhile the medicine livestock diminished. Escalation of diarrhea cases especially in children and limited community health surveillance in Bima Town were also identified by the team. The second team was in a mission to accomplish environmental studies associated with flood disaster and implement rainwater harvesting technology. Rainwater harvesting technology implemented based on data collection and analysis from the first team. Rainwater harvesting technology used to supply community water necessities since the groundwater in disaster area remain muddy and smells. Application of rainwater harvesting equipment completed at Penanae and Mpunda Primary Health Care. Deployment of the UGM Bima disaster response team expected to spring positive benefits to the flood affected communities, and in addition expected that the assistance from UGM established sustainably.
