Analisis dan Mitigasi Bencana Alam Kekeringan terhadap Kebutuhan Air Baku di Perumahan Antasari Permai Sukabumi Bandar Lampung

This research aims to carry out a drought analysis of raw water needs in these settlements, as well as designing mitigation strategies to overcome this problem. The research method involves field surveys and drought index analysis using the Standardized Precipitation Index (SPI) method. The results of analysis using the SPI-3 and SPI-12 methods show that in the last 20 years the nature of the drought index in the Antasari Permai Housing Complex has been dominated by "Normal" characteristics. The times that should receive more attention are June to November because in these months the drought shows the characteristics of "Extreme Dry" compared to other months. As a response, the proposed mitigation strategies can be implemented in the short term or long term. In the short term, mitigation is carried out by supplying clean water using water tankers, PDAM or by building rainwater reservoirs. Meanwhile, the long term is carried out in an integrated and sustainable manner by considering natural phenomena, weather anomalies, groundwater cycles. Maintaining the groundwater cycle by means of reforestation and groundwater conservation planning in the form of biopores or infiltration wells. Implementation of this strategy is expected to increase the resilience of settlements to drought and ensure the availability of adequate raw water for community needs.

INNOVATIVE STRATEGIES FOR MANAGING HYDROMETEOROLOGICAL DISASTER RISKS: OPTIMIZING ENVIRONMENTALLY FRIENDLY DRAINAGE SYSTEMS (ECO-DRAINAGE) TO PREVENT FLOODING AND OVERFLOW IN CLIMATE CHANGE ADAPTATION IN KARAWANG REGENCY

Urban drainage is a network system for waste disposal in urban areas that functions to manage or control surface water, so that it does not disrupt or harm the community and provides benefits for human activities. This research aims to create synergy and steps for the implementation of eco-drainage in the urban characteristic conditions of Karawang Regency. The method used involves data collection through observation, interviews, historical data analysis, and mapping based on SNI Number 02-2406-1991 regarding the General Planning Procedures for Urban Drainage. The research results indicate that the Eco drain infrastructure consists of 7 elements, namely rainwater harvesting, infiltration wells, retention ponds, trash filters, bioremediation, biofilters, and water quality treatment using constructed wetlands. Meanwhile, the local government of Karawang Regency does not yet have the infrastructure to implement eco-drainage. After conducting an analysis, it was determined that among the 7 elements of eco-drainage, rainwater harvesting is the most needed to address the issues of flooding and drought in the Karawang area. The research results also include calculations and explanations regarding the Eco drain facilities for rainwater collection on a land scale and environmental/community storage tanks, as well as the quality of rainwater in Indonesia.

PENERAPAN KONSEP ZERO DELTA RUNOFF DENGAN TEKNOLOGI EKODRAINASE PADA ARIA REMPOA TOWNHOUSE, TANGERANG SELATAN

The increasing need for basic urban facilities and infrastructure, such as housing, can result in a reduction in green open land which can reduce the ability of water to infiltrate into the ground and increase surface runoff. Aria Rempoa Townhouse, a housing complex that is still in the development process, may have problems like these. Therefore, it is necessary to implement the zero delta runoff concept with ecodrainage technology such as retention pond and infiltration well. Research was carried out on the design flood at the outlet before the townhouse is built and after the townhouse is built if the zero delta runoff concept is applied with retention pond and infiltration wells. There are 3 scenarios, scenario 0 before the townhouse is built, scenario 1 after it is built without ecodrainage technology, scenario 2 after it is built with a retention pond, and scenario 3 after it is built with infiltration wells. The research results show that scenario 2 fulfills the concept of zero delta runoff with a pool area of 42 m2 with a depth 3.5 m and 2 outlet pipes with diameter 10 inches without doors discharge the design flood at the outlet of 0,281 m3/sec which is smaller than design flood at the outlet before the townhouse is built of 0.288 m3/second.

Optimization of Biopori and Construction of Absorption Wells in Blawi Village to Overcome Annual Flood Disasters

This activity was carried out in Blawi Village - Lamongan Regency. Floods often hit this village due to overflowing rivers and waterways due to high rainfall. In practice, infiltration wells for rainwater have never been implemented in Blawi Village, while biopores were only added at several points because this activity continued the previous year's activities. This community service activity made several rainwater infiltration wells and added biopores to accommodate the surface runoff water component from rainfall. This Student Organization Capacity Strengthening Program (PPK ORMAWA) activity was carried out by the Civil Student Association (HMS) of Lamongan Islamic University in collaboration with Blawi Village officials and residents for conservation-based waterlogging mitigation. Infiltration wells and biopores use a method that is very easy to implement, this activity is also useful for maintaining groundwater and utilizing biopore leaves for compost. This program can reduce the problem of inundation in Blawi Village during the rainy season.

Perencanaan Jamban Sehat untuk Rumah Studi Kasus Desa Weninggalih Kabupaten Bogor

A livable house must meet various requirements, one of which is health requirements, so that the occupants remain healthy. One of the important things that must be in a house is a latrine or bathroom. Inappropriate latrines facilitate the spread of certain diseases such as diarrheal diseases. The planning and manufacture of family latrines must follow the criteria in accordance with existing standards such as layout, water sources, construction, and also the materials. With the existence of family latrines that meet the criteria, a healthy society will be realized, as an effort to implement a healthy lifestyle for the community which was proclaimed by the Ministry of Health as a Clean and Healthy Lifestyle (PHBS). The purpose of this study was to determine the feasibility of sanitation and environmental health in Weninggalih village, Bogor Regency. Methods The research is conducted by conducting a field survey. Data collection is done by visiting the house one by one, where the physical components seen are focused on the bathroom and its supporting facilities. Based on the results of the study, it is known that the houses in the village of Weninggalaih are still very far from being feasible. This can be seen from the construction of the house with earth floors and tends to be humid. In addition, the walls use cubicles that allow air from outside to easily enter, including various small animals, the absence of a low roof, and the absence of a proper bathroom. Therefore, it is recommended to the local authorities to improve the facilities in every resident's house, including making a latrine in each house, constructing drainage channels and also infiltration wells to reduce household waste, including providing space between the house and the animal cages.

Water Infiltration Policy for Urban Flood Management

This research was conducted to determine the implementation of water absorption policies for flood management in urban areas, especially in the city of Cirebon at the Cirebon City Public Works and Spatial Planning (DPUPR) department. The research approach used is normative juridical, conceptualizing law as written norms so that this research emphasizes studies in the form of legislative products, namely those that regulate water absorption such as regional regulation number 38 of 2019 concerning the implementation of groundwater conservation through infiltration wells and infiltration holes. biopore. Policy implementation in flood management by the Cirebon City PUPR Service has included handling floods and puddles as a priority in the Regional Government Work Plan (RKPD) for 2025. For handling urban drainage, the PUPR Service's work target is to reach up to 83% by 2024, and 86% for 2025, and 89% for 2026. One of the strategies taken includes the creation of retention ponds, absorption wells and eco-drainage. However, there are still several obstacles in implementing this policy, such as limited resources and lack of community participation. To overcome these obstacles, efforts need to be made such as increasing the budget, providing adequate human resources, and educating the public about the importance of water absorption. Overall, the implementation of the water absorption policy for flood management in Cirebon City has shown a positive direction. With continued efforts and collaboration from various parties, it is hoped that this policy can be more effective in minimizing the risk of flooding in urban areas.

Eco-Drainage Combined with Infiltration Wells for Sustainable Flood Control

Rawa Makmur is located in Muara Bangka Hulu District, Bengkulu City, with an area of 150 hectares and a population of 1,468 people. This area in the form of a swamp has experienced a 30% change in the shape of the land in a period of 3 years and causes flooding during the rainy season. The existing drainage system is unable to accommodate and drain the river. This problem requires planning an environmentally friendly drainage system design (eco-drainage), one of which is using infiltration wells. This study aims to overcome stagnant water in Rawa Makmur Village by implementing an environmentally oriented drainage system (eco-drainage) using infiltration wells. The data used are primary data (measurement of canal dimensions) and secondary data in the form of rainfall data, topographic surveys, soil testing and other supporting data which are processed using hydrological analysis and hydraulic analysis. Based on the results of data processing and analysis, it was found that the intensity of rainfall with a return period of 10 years was 11.25 mm/hour and the planned flood discharge was 0.1039 m3/s. The calculation results are used to design environmentally sound drainage using infiltration wells. The results of the analysis obtained specifications for the depth of infiltration wells of 1.50 m, a diameter of 0.5 m, the distance between infiltration wells is 50 m. The planned eco-drainage can accommodate 0.2943 m3 and can delay water runoff for 3.5846 minutes before seeping into the ground.

Analysis on unconfined groundwater availability during dry and rainy season using dynamic approach in Ngemplak, Sleman, Yogyakarta, Indonesia

Groundwater is a natural resource with disparity across the different regions throughout time. In comparison to surface water, the groundwater in unconfined aquifers is easily accessible and generally of good quality. Groundwater macro zoning is classified into three, namely water catchment areas, transition areas, and groundwater discharge areas. Based on the macro zoning, previous research has mostly been carried out in catchment areas and discharge areas with a focus on groundwater potential and temporary groundwater conditions. The dynamics of groundwater availability, especially in the water transition zone, has not been studied much, even though the dynamics of groundwater availability in the transition zone plays a vital role for areas in the discharge zone. This study identified the availability of groundwater during rainy and dry seasons in groundwater transition zone. Groundwater availability was assessed through a dynamic discharge approach. The study variables included the hydraulic conductivity of the aquifer, the hydraulic gradient, and the cross-sectional area of the aquifer. Dynamic discharges were analysed during the rainy and dry seasons. The results showed that the availability of groundwater during the rainy season was 4,333,906.1 liters/day and 3,898,850.4 liters/day during the dry season. Based on the calculation of the dynamic discharge (Q), the decrease in the quantity of groundwater is affected by the variable hydraulic gradient (I) and cross-sectional area of the aquifer (A). The numbers of these two variables are smaller during the dry season than the rainy season. The decrease in the quantity of groundwater during the dry season is of course closely related to reduced rainfall which is a source of infiltration and percolation. Reduced rainfall causes the groundwater level to decrease, then technically reduces the groundwater hydraulic gradient (I) and aquifer cross-sectional area variable (A). There was no indication of groundwater scarcity in the study area. This study can serve as a reference related to the application of dynamic discharge theory to assess groundwater availability. Periodic monitoring of groundwater quantity, rainwater harvesting, and intensification of water infiltration wells can be carried out as a recommendation to anticipate problems related to groundwater availability in the study area. This study can serve as a reference related to the application of dynamic discharge theory to assess groundwater availability.

SURFACE FLOW ANALYSIS AS AN EFFORTS FLOOD MITIGATION

Problems that often arise in the city of Cirebon are flooding caused by rain, land changes not supported by adequate infrastructure, narrowing of drainage channels and sedimentation of channels. This is the location where flooding often occurs in the Pemuda Street area and its surroundings. Therefore, it is necessary to carry out research on surface flow analysis as an effort to handle floods with the aim of inundation management strategies to reduce excessive rainwater runoff in drainage areas and channels. The research methods used were problem identification, literature study, data collection, analysis and design planning. The results can show that inundation is handled in two ways, first by changing the dimensions of the channel at the initial height H to 0.45m, it still experiences inundation, this is due to the difference in elevation which causes inundation in the channel. There was a change in the flood inundation area to 23,127 ha from the original 58,958 ha, meaning that the flood free area increased from 9,388 ha to 35,831 ha. The second way is by making 378 infiltration wells spread across 34 channels that experience flooding. With these infiltration wells, the flooding can be reduced to a minimum from an area of ​​23,127 ha to 0.040 ha. The success rate for flood management efforts reached 99.908%, with failure being 0.092%. Of the area of ​​68,346 ha, the flood-free area reached 68,306 ha and the remaining inundated area was 0.040 ha..

THE INFLUENCE OF URBANIZATION TO THE WATER INFILTRATION ZONE ON BANYUMANIK SUB-DISTRICT, SEMARANG CITY, CENTRAL JAVA, INDONESIA

The high growth of developed land in the Banyumanik Sub-District, especially in residential and commercial areas, occurred due to the high demand for housing, lifestyle fulfillment, and speculation and investment by the upper-middle-class society. The reduction or loss of land with vegetation cover in the Banyumanik Sub-District increases the potential for flooding due to more significant surface runoff than water absorption during heavy rainfall. This research used integrated spatial analysis to generate information on the critical level of water infiltration in the research area using the Analytical Hierarchy Process (AHP) method. Both primary and secondary data collected will be compiled and subjected to spatial analysis to address the issues at hand. The weight of each parameter class produced by the AHP method is used for modeling and includes infiltration rate, land use, slope, and lithology parameters. The criticality level of the water infiltration zone in the southern part of Banyumanik Sub-District indicates that the water infiltration condition in the research area consists of good class at 13.589%, naturally normal at 18.405%, started to be critical at 16.114%, slightly critical at 20.764%, critical at 18.286%, and very critical at 12.841%. Changes in land use in the research area have become the primary factors causing alterations in the water infiltration conditions. Infiltration wells are one of the solutions to mitigate runoff as part of sustainable rainwater management. The government plays a crucial role as a policymaker in making decisions to address issues related to urban area development towards sustainable development.

EFFECTIVENESS OF ABSORPTION WELLS USING THE SUNJOTO METHOD TO CONTROL FLOODING IN THE VILLAGE OF NGRASEH BOJONEGORO

Infiltration wells are a form of hydrological infrastructure used to manage rainwater. Infiltration wells are usually built as part of a rainwater management system to soak rainwater into the ground and reduce surface waterlogging as well as slow down surface runoff and allow rainwater to seep into the ground to renew aquifers or prevent waterlogging. Maintaining groundwater levels is an important step in sustainable water resource management. The aim of this research is to plan effective infiltration wells to replace rainwater catchment areas lost due to building construction. The planning of this infiltration well uses the Sunjoto method. From the research results, it was found that an effective infiltration well design was calculated using the Sunjoto method. With the data, each roof area of ​​the house has an optimum number of infiltration wells with a planned infiltration well diameter of 1 m with a depth of 2.5 m with an effective depth according to the calculations is as follows: 60 m2 number of 1 unit of absorption well with an optimum depth of 2.82 m, 80 m2 number of 2 units of absorption well with an optimum depth of 3.76 m, 100 m2 number of 2 units of absorption well with an optimum depth of 4.7 m, 120 m2 number of 2 units of infiltration wells with an optimum depth of 5.64 m, 140 m2 number of 3 units of absorption wells with an optimum depth of 6.58 m, 160 m2 number of 3 units of absorption wells with an optimum depth of 7.52 m, 180 m2 number of 3 units of absorption wells with an optimum depth of 8.46 m, 200 m2 total of 4 units of infiltration wells with an optimum depth of 9.4 m.

Investigation of the discharge performance in infiltration wells based on several soil subgrade models

Heavy precipitation would result in hydrometeorological disasters such as landslides and floods. In general, disasters cause hazardous situations and property loss. Infiltration wells are water and soil conservation techniques that can reduce surface runoff and increase infiltration to mitigate the effects of hydrometeorological disasters. However, evaluations of geotechnical properties have not yet jointly or actively considered these environmental developments. This paper aims to analyse the wide range of soil types against several diameters and depths of the holes. The variation in soil varied from type 1 to 6, containing different properties and consistencies. The holes diameter used are 0.4m, 0.5m, 0.6m, 0.7m, and 0.8m, associated with several depths; 0.5m, 0.75m, 1m, 1.25, and 1.5m. The analysis was conducted with Geostudio SEEP-W in different model variations to obtain the well’s discharge value. The result shows that all the depth depicts similar behaviour of the discharge well. The sand model has the highest value of all categories, with the second place being the sand-clay layer model. In contrast, the clay simulation generates the lowest value of this research. This output offers a strong recommendation between infiltration well structure and soil parameters, which show sand is the most required property to increase the performance of hole infiltration.

Groundwater Management in Coastal Area of Batang Regency to Anticipate Sea Water Intrusion

Of the water sources that exist on earth, almost all of human’s daily water needs such as drinking, bathing and washing are sourced from groundwater. Uncontrolled extraction of groundwater can cause various impacts on the environment, such as lowering of the groundwater level and seawater intrusion. Efforts to manage groundwater need to be carried out so that its availability is always maintained. The initial step of this effort is to formulate a management model as a basis for policy determination. For this reason, in this study a dynamic modeling simulation was carried out using dinamic program. The results of the research show that the priority for groundwater management efforts in the coastal area of Batang Regency is to reduce the use of groundwater for the domestic sector which can be done through saving groundwater use or by increasing the capacity of the local water company. Besides that, management through artificial recharge by making infiltration wells or biopore holes is also effective in maintaining the availability of groundwater in this area.

The Environmental Impacts of Post-Disaster Rehabilitation and Reconstruction Facilities in Garut Regency-Indonesia

Garut Regency is referred to as a miniature natural disaster in Indonesia. This is because Garut Regency is surrounded by active mountains with topographic characteristics of the northern part consisting of plateaus and mountains, while the southern part of the surface has a steep steepness and in some areas is unstable. Garut Regency, which is geographically prone to disasters, is the duty of the District Government and the community to protect Garut Regency and the community from disasters. As part of the overall disaster management, the implementation of rehabilitation and reconstruction stages becomes an important stage. Analysis of environmental impacts of post-disaster rehabilitation and reconstruction facilities is an activity needed to assess the impacts that arise on post-disaster rehabilitation and reconstruction facilities in Garut Regency. The research objective was to analyze the environmental impact of post-disaster rehabilitation and reconstruction facilities in Garut Regency on domestic solid waste generation and runoff. The results showed that the activities in post-disaster rehabilitation and reconstruction amenities in Garut Regency will change the land use, generate the solid waste of 1,07 m3/day and runoff of 2,73 m3/day. Land use changes can be maintaining by providing the green open space according to the regulation standard, moreover, the possible treatment for solid waste management is through TPS 3R (reduce, reuse, recycle at temporary waste collection site (TPS)) meanwhile runoff management can be managed by providing the proper drainage and infiltration wells.

Monitoring Dan Evaluasi Jaringan Drainase Yang Ramah Lingkungan Di Perumahan Villa Delima Mayang Kota Jambi

Novel approach to roof rainwater harvesting and aquifer recharge in an urban environment: Dry and wet infiltration wells comparison

In urban environments there is a severe reduction of infiltration and groundwater recharge due to the existence of large impervious areas. During rain events, large volumes of water that could have recharged groundwater and surface water bodies are diverted into the municipal drainage system and lost from the freshwater storage. Moreover, extreme rain events impose high peak flows and large runoff volumes, which increase the risk of urban floods. Recent studies have suggested the use of rainwater harvesting for groundwater recharge, as a plausible solution for these challenges in dense urban environments. While the benefits of this approach are well understood, research on its practical, engineering, and hydrological aspects is relatively limited. The objective of the present study was to examine the use of infiltration wells for groundwater recharge with harvested rainwater collected from building rooftops under Mediterranean climate conditions. Two types of wells with similar hydraulic and technical properties were examined: a well that reaches the groundwater (wet well); and a well that discharges the harvested water into the unsaturated zone (dry well). Infiltration capacities of the wells were compared in controlled experiments conducted during summer months, and in operational recharge of harvested rainwater, during winter. Both dry and wet wells were found to be suitable for purposes of groundwater recharge with rooftop-harvested rainwater. Infiltration capacity of the wet well was about seven times greater than the infiltration capacity of the dry well. While the infiltration capacity of the wet well was constant throughout the entire length of the study (∼10 m3/h/m), the dry well infiltration capacity improved during winter (from 0.5 m3/h/m to 1.5 m3/h/m), a result of development of the dry well with time. Considering Tel-Aviv, Israel, as a case study for a dense modern city in a Mediterranean climate, it is demonstrated herein that the use of infiltration wells may reduce urban drainage by ∼40 %.

Recarga artificial mediante pozos secos

Managed aquifer recharge (MAR) is a water management strategy that uses aquifers for the seasonal or inter-annual storage of exceeding surface water. Systems that implement artificial recharge use infiltration ponds or shallow or deep infiltration wells. While articifial recharge through infiltration ponds requires large areas and infiltration through deep wells demands high investment, infiltration through drywells, which inject water to the vadose zone, is often a preferred option because of its low cost and relatively easy implementation. We present results of detailed numerical simulations to assess the operation of a single drywell to implement an artificial recharge system. We demonstrate that depending upon the distribution and property of the geological materials that compose the subsurface, the operation of the well can produce quite different results in terms of effective recharge. We expect that these findings will help design real MAR systems and provide supporting information for decision-makers in charge of approving and financing such water management systems.
