Abstract

Kualitas air tanah memiliki peran penting untuk berbagai kebutuhan, mulai dari konsumsi hingga industri. Berdasarkan Permenkes No. 32 Tahun 2017, standar kualitas air tanah menetapkan batas-batas tertentu agar air tanah dangkal dapat digunakan secara aman dan layak tanpa menimbulkan dampak kesehatan, teknis, maupun estetika. Namun, tidak semua air tanah dangkal memenuhi standar tersebut, terutama karena adanya potensi kontaminasi dari aktivitas manusia. Oleh karena itu, penelitian ini bertujuan untuk menilai kualitas air tanah dangkal di Kelurahan Keputih menggunakan metode perbandingan baku mutu yaitu Permenkes No. 32 Tahun 2017 untuk kebutuhan higiene sanitasi, kemudian dianalisis terkait pengaruh lingkungan lokasi penelitian yang juga dekat dengan IPLT terhadap air sumur. Hasil analisis dari penelitian ini diketahui bahwa kualitas air tanah di Kelurahan Keputih tidak memenuhi semua baku mutu, diantaranya adalah parameter Total Dissolved Solids (TDS) yang terdapat pada sumur 2 dan disebabkan oleh tingginya garam terlarut di dalam sumur, Mangan yang terdapat pada sumur 1 dan 3 yang menyebabkan sumur memiliki rasa dan bau logam, Fluorida pada sumur 4 yang dipengaruhi oleh variasi batuan, Nitrat yang terdapat pada sumur 3 dan 4 yang disebabkan oleh pencemaran limbah domestik dan Total coliform yang terdapat pada sumur 2 dan 3.

Abstract

Rapid population growth in Surabaya has been accompanied by various environmental challenges, one of which was flooding on Jalan Panjang Jiwo. In addition to high rainfall intensity, the city’s flat topography and its location in the downstream area of the Brantas Watershed contributed to the occurrence of flooding. Land conversion into built-up areas also led to a reduction in natural infiltration areas, resulting in increased surface runoff. Furthermore, the suboptimal performance of the existing drainage system made it unable to adequately convey rainwater discharge during periods of high rainfall intensity. This study aimed to examine the potential application of the eco-drainage concept through the injection well method as an alternative flood control measure in the Jalan Panjang Jiwo area. Injection wells were selected because this design was intended to support the infiltration process by allowing rainwater to pass through impermeable or low-permeability topsoil layers. Unlike natural infiltration systems, which relied solely on surface soil permeability, injection wells enabled water to penetrate these layers and reach more permeable soil strata below. Therefore, this method was considered effective for application in urban areas dominated by built-up surfaces with limited green open spaces. The analysis was conducted using hydrological and hydraulic approaches, supported by modeling with EPA SWMM 5.2. Through a trial-and-error process involving calculation and design evaluation, an optimal injection well design with a diameter of 3.25 meters and a depth of 25 meters was obtained. Based on flood discharge estimates under existing channel conditions, a total of six injection wells were required to accommodate surface runoff. The results of this study were expected to serve as technical recommendations for the development of sustainable urban drainage systems, particularly in flat areas with high runoff levels such as Surabaya.

Abstract

Indonesia, as a country heavily dependent on the agricultural sector, faces significant challenges regarding water availability, especially during prolonged dry seasons. The mismatch between crop water requirements and available irrigation water often leads to reduced agricultural productivity, particularly in areas with limited irrigation systems, such as the Wilangan Irrigation Area (DI) in Ponorogo Regency. This study aims to design an optimal cropping pattern by balancing crop water requirements and irrigation water availability in the DI Wilangan, Ponorogo Regency. The study aims to provide an efficient solution for irrigation management and cropping pattern planning. The method used in this study is a quantitative analysis utilizing hydrological and climatological data from 2014 to 2024. Water availability is calculated using the F.J. Mock method, while crop water requirements are estimated using the FAO Penman-Monteith method to determine reference evapotranspiration (ETo) and net irrigation demand. The results show that the PTT IV cropping pattern alternative, with a paddy-paddy-secondary crop pattern starting in the second period of December, results in the lowest water demand of 5.447 lt/second or equivalent to 0.0054 m³/second. The dependable discharge during this period reached 0.071308790 m³/s, ensuring that irrigation water needs can be fully met without deficit. Therefore, the PTT IV cropping pattern is recommended as the most efficient and sustainable option for irrigation water use in the area.

Abstract

Flooding problem in Medaeng Village, Waru District, Sidoarjo Regency, is a crucial issue caused by changes in land use, high rainfall, and suboptimal drainage channel conditions and lack of maintenance. Initial studies indicate that drainage channels in Medaeng Village are unable to accommodate large volumes of water, exacerbated by high sediment and dense settlements that reduce infiltration areas. This study aims to analyze the drainage channel capacity based on the design flood discharge. The research method involves primary and secondary data. Analysis of maximum and average rainfall uses the Thiessen Polygon method, frequency distribution analysis uses the Log Pearson Type III method, and the Smirnov-Kolmogorov goodness-of-fit test. Rainfall intensity is calculated using the Mononobe method, design flood discharge calculation uses the rational method, and storage capacity uses the rational method. The results of the analysis show that Qhidrologi is 0.689 m3/s (2 years), 0.855 m3/s (5 years) and 0.955 m3/s (10 years). Meanwhile, the existing Qhydrology is 0.0693 m3/s (channel 1), 0.0588 m3/s (channel 2), 0.2163 m3/s (channel 3), 0.2315 m3/s (channel 4), 0.2491 m3/s (channel 5). The comparison between (Qhydrology>Qhydrology) shows that all channels 1 to 5 have a small capacity and have the potential to cause flood risk. The results of this analysis can be the main basis for technical planning to increase the capacity of the Medaeng Village channels and a reference for further studies on more comprehensive flood mitigation.

Abstract

Penjaringan Asri Street often experiences flooding during high rainfall due to land conversion, residential growth, and blockage of drainage channels by garbage, sedimentation, and wild vegetation. High population density reduces infiltration areas so that runoff discharge increases and exceeds the channel capacity. This study aims to assess the capacity of drainage channels to accommodate design flood discharge with return periods of 2, 5, and 10 years. The data used include the results of channel measurement surveys, rainfall for the period 2014–2024, and topographic maps. Hydrological analysis was carried out using the Thiessen Polygon method, Log Pearson III Distribution, and the Rational Method. Based on the analysis results, the design flood discharge for each return period shows that the 2-year return period is 2,069 m3/second, the 5-year return period is 2,439 m3/second, and the 10-year return period is 2,640 m3/second.  Meanwhile, based on the comparison of the design discharge (Qhydrology) with the hydraulic capacity (Qhydraulic), all channels exhibited flood conditions for return periods of 2 years, 5 years, and 10 years. This is due to the higher Qhydrology value compared to Qhydraulic, indicating that the existing channel cross-sectional capacity is unable to accommodate the design flood discharge. Therefore, it can be concluded that the channels in the Penjaringan Asri area are not yet capable of accommodating the design flood discharge. Therefore, channel capacity increases and routine maintenance are required to ensure the system functions optimally in reducing flooding.

Abstract

The Gunung Anyar area of Surabaya has experienced rapid population growth and development, leading to a decline in green open spaces and water infiltration areas. This condition increases the risk of inundation and flooding due to the limited capacity of the existing drainage system. This study aims to evaluate the capacity of the existing drainage channels against the design flood discharge based on hydrological and hydraulic analyses. The hydrological analysis shows that the highest design flood discharge occurs in Sub-watershed 5 at 0.404 m³/s, while the lowest is found in Sub-watershed 6 at 0.096 m³/s. Meanwhile, the hydraulic analysis indicates that the highest channel capacity is in Channel 10 at 0.858 m³/s, and the lowest in Channel 6 at 0.097 m³/s. A comparison between hydrological and hydraulic discharges shows that several channels have smaller capacities than the design flood discharge (Q_hydraulic < Q_hydrologic), which may lead to inundation, particularly in Channels 1, 2, 5, 6, and 7. On the other hand, Channels 3, 4, 8, 9, and 10 are still capable of accommodating runoff effectively. The results of this evaluation can serve as a basis for planning drainage capacity improvements in the Gunung Anyar area to reduce future flood risks
