Jejak Manajemen Air di Masa Hindia-Belanda; Identifikasi Saluran Air di kawasan Stasiun Bogor

This article describes the identification of the trace of the water management system during the Dutch East Indies era, in the form of a water channel found in the Bogor Station area. The analysis will be viewed from the spatial context; the significance of the water channel with the nearest river, the significance of the water channel to the nearest public facility, and its relevance to the racial urban space in Bogor. This research used a historical method that consists of four stages; heuristics, critics, interpretation, and historiography. Observations were made to explain the physical form and the estimated period of water channel construction. The results showed that the water channel near the Bogor Station was made with modern technology. In the past, the channel may have functioned as drainage that connected to the Ci Pakancilan. The location of the waters channel adjacent to public facilities and government administrative centers showed the accuracy of the Department of Public Works in anticipating floods and puddles in the area of European activity.

COMPARISON OF LAND-BASED TEST SETUPS FOR A BALLAST WATER MANAGEMENT SYSTEM

Two land-based setups were tested at different locations using the same combined treatment technologies, to assess the effect of different control and treated tanks condition as well as overall effectiveness of a ballast water treatment system. The test procedure included a five day storage period of organisms in the control and treated tanks as specifically advised in the type approval procedure for shipboard and land-based tests described in the IMO Guideline ‘G8’. The configurations and materials of control and treated tanks used in each test location were different resulting in invalid test results at one testing location.

Selected Issues of Adaptive Water Management on the Example of the Białka River Basin

Water is a fundamental resource needed for human life and functioning and the environment. Water management requires a comprehensive, adaptive approach that also considers the dynamics of changes in the water management system. This is particularly important in areas where different groups of stakeholders intertwine, whose needs often contradict, which hampers effective water management, particularly in places of high natural value. This research aimed to analyze selected issues in water management in the Białka River Basin in Southern Poland. The analysis was based on a review of scientific publications, internet sources, and a survey on water management in the basin. Our research shows that the dominant issues in the study area are the flood risk and water pollution related to, among other factors, the intensive development of tourism. Moreover, the effective management of water resources is hampered by poor communication between the administration and stakeholders, which results in a low level of knowledge, negative attitudes towards nature protection, and the emergence of conflicts. The main conclusion of this paper indicates that, despite the existing social potential for implementing comprehensive water management methods, the lack of an appropriate legal framework prevents the implementation of concepts such as Adaptive Water Management.

The Preliminary Study for Increasing the Productivity of Unit Tamban Lowland Irrigation Area based on Fact Findings of Observations

Unit Tamban is a fork system of lowland irrigation areas in Kapuas District. It has three primary canals, and each of them has a settling pond at the end. Most of the 3,506 ha planting area still apply once a year cropping patterns. A quick assessment based on field observations is carried out to determine the existing problems, including water management, water quality, and soil quality. The problem in the water management system is silting in the primary and secondary canals. The settling pond at the primary canal was no longer functioning, and it makes the silting worse because the water flow became uncontrolled. Water quality is measured with pH and TDS, the average pH at canal water was 4,22, and TDS was 71 mg/l. The soil type is mainly acid sulphate with pyritic materials, mostly 70 cm below the surface. Increasing cropping patterns twice a year requires improving the water circulations and increasing the soil pH higher than five. The problem in the secondary canal is expected to solve by changing the flow pattern from two way to 1-way flow is needed to avoid dead spots of water so that the leaching processes can work well.

Reinventing Smart Water Management System through ICT and IoT Driven Solution for Smart Cities

Purpose: Worldwide water scarcity is one of the major problems to deal with. Smart Cities also faces this challenging problem due to its ever-increasing population and limited sources of natural water. Additionally, careless usage of water and large water wastage has made the water issues as a serious concern. Today Smart Cities are using advanced technical solutions to deal with various problems, to deal with water shortage problems, Smart Cities uses Smart Water Management System, an intelligent system which distributes and control existing water supply on need basis, and also it facilitates recycling of water for again using for specific activities. In this paper I have provided the overview of Smart Water Management System, its features, and functionalities. I also reviewed available literature on Water Management Systems for Smart Cities and considering the latest tools and technologies and understanding some of the limitations of existing Smart Water Management Systems, I proposed an easy to develop, operate and maintain Smart Water Management Solution called as "iWMS". The proposed conceptual framework of iWMS is modular and is based on secure Blockchain based Application Layer. The iWMS solution supports entire water management and recycling functioning cycle and can easily integrate with other services of Smart Cities. The evaluation of iWMS framework provided very encouraging results. It is revealed that iWMS meets the stated objectives of water savings through automated operation and also through controlled water recycling. Unlike other Smart Water Management Systems, iWMS also carefully complies the cybersecurity requirements. Based on evaluation, the advantages, and limitations of iWMS are also stated in this paper. Finally, I have also specified the future plans about iWMS to undertake its full-fledged implementation and addressing of its limitations. Design/Methodology/Approach: Primary Data collection through Interviews and Questionnaire responses from Industry Professionals, SMEs, and Researchers working on development, operation, and maintenance of Water Management Systems in Smart Cities and secondary data collected through detailed review of existing literature containing Journal Papers, Conference Papers, and Whitepapers available on Water Management Solutions for Smart Cities, are used to derive the new findings and results presented in this research paper. Findings/Result: Smart Water Management System not only efficiently handles water distribution across Smart Cities but also plays an active role in Water Recycling, Water Control and Monitoring, Estimation of the peak water requirements, and detection of water leakage if any.
