Abstract

The drainage system in Tambak Rejo Indah Housing, Waru, Sidoarjo, is currently unable to accommodate rainfall runoff effectively, resulting in frequent ponding that disrupts residents’ activities. This study aims to analyze the capacity of the existing tertiary drains across several segments up to the secondary drain and redesign the channel dimensions to meet the required design discharge. Hydrological analysis was carried out using the Log Pearson Type III method to determine the design rainfall, and the Mononobe formula was applied to calculate rainfall intensity. The design discharge was established using a 10-year return period in accordance with the Ministry of Public Works Regulation No. 12/PRT/M/2014. The capacity of the existing drains was compared with the design discharge to identify channels that are insufficient to convey the required flow. New channel dimensions were then determined using a trial-and-error approach until sizes capable of conveying the design discharge were obtained. The analysis shows that several tertiary drains and their respective segments—Tertiary 1 (segments 2–3), Tertiary 2 (segments 4–5), Tertiary 4 (segments 9–10), Tertiary 5 (segments 12–13), Tertiary 6 (segments 16–17 to 26–27), and Tertiary Nilam Barat Main Road (segments 28–31)—are unable to convey the design discharge of 0.80–1.10 m³/s, with existing capacities of only 0.35–0.52 m³/s. Through the trial-and-error process, channel dimensions capable of accommodating the 0.80 × 0.80 m design discharge were obtained, including redesigned dimensions of 0.50 m × 0.50 m for Channel 1 (segment 2–3). This redesign is expected to improve flow efficiency and reduce the potential for ponding within the residential area.

Abstract

Pertumbuhan wilayah perkotaan yang pesat di Kota Surabaya telah menyebabkan terjadinya perubahan tutupan lahan yang signifikan, khususnya pada area vegetatif. Urbanisasi yang tidak terkendali memicu alih fungsi lahan hijau menjadi kawasan terbangun, seperti permukiman, kawasan industri, dan infrastruktur. Tujuan dari penelitian ini adalah untuk mengkaji perubahan pada indeks kerapatan vegetasi menggunakan pendekatan Normalized Difference Vegetation Index (NDVI) menggunakan data citra satelit Landsat 8 yang dianalisis melalui Sistem Informasi Geografis (SIG) pada tahun 2015 dan 2025. Analisis dilakukan dengan melakukan klasifikasi nilai NDVI dalam empat kategori: non-vegetasi (-1,00 - 0,00), vegetasi rendah (0,0–0,25), sedang (0,25–0,5), dan tinggi (> 0,5). Hasil analisis menunjukkan bahwa klasifikasi vegetasi rendah (NDVI 0,0–0,25) mengalami peningkatan dari 1.009,62 Ha (53,44%) pada tahun 2015 menjadi 18.908,64 Ha (57,57%) pada tahun 2025. Sebaliknya, vegetasi tinggi (NDVI > 0,5) mengalami penurunan dari 3.646,98 Ha (11,10%) menjadi 3.397,86 Ha (10,35%). Penurunan tersebut mengindikasikan terjadinya degradasi lingkungan yang signifikan akibat berkurangnya area hijau. Hasil validasi lapangan menunjukkan tingkat akurasi klasifikasi NDVI cukup tinggi dan sesuai dengan kondisi tutupan lahan aktual. Perubahan ini mengindikasikan adanya peralihan fungsi lahan secara besar-besaran dari lahan vegetatif menjadi kawasan terbangun seperti permukiman dan industri. Temuan ini menunjukkan bahwa perubahan tutupan lahan di Surabaya telah berdampak langsung terhadap penurunan kualitas lingkungan, termasuk meningkatnya suhu udara permukaan. Penurunan tutupan vegetasi secara langsung berdampak pada meningkatnya suhu udara dan memperburuk kondisi lingkungan perkotaan. Oleh karena itu, hasil studi ini diharapkan dapat menjadi bahan pertimbangan bagi pemerintah daerah dan perencana tata ruang dalam merumuskan kebijakan perlindungan area hijau publik dan pengendalian konversi lahan yang berkelanjutan di Kota Surabaya.

Abstract

Groundwater management in confined aquifers in Probolinggo Regency is currently under significant pressure due to industrial growth and the impacts of climate change. This study aimed to formulate adaptive policy strategies by synergizing internal technological strengths and the latest regulatory dynamics. The scope of the experiment included identifying internal and external strategic factors through structured interviews and literature reviews validated by technical stakeholders. The method used was the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, using the internal factor analysis strategy and external factor analysis strategy matrices to determine the organization's position on the Cartesian diagram. The results of the study showed that internal strengths recorded a total score of 2.4498, while external opportunities recorded a total score of 0.7199. The position analysis places groundwater management in Quadrant I (aggressive) with coordinates (2.3170; 0.5929). The main findings indicated that the organization has a significant competitive advantage through the integration of geospatial data and cutting-edge sensor technology. The formulated strategy includes a transformation towards digital-based management, strengthening science-based conservation through injection technology, and diversifying external funding. This study concludes that implementing aggressive strategies that integrate technological innovation and law enforcement is essential to ensure aquifer sustainability and mitigate the risk of seawater intrusion. The use of this policy roadmap is expected to serve as a guide for local authorities in realizing sustainable groundwater management amid the threat of overexploitation.

Abstract

Abstract — This study aims to evaluate the feasibility of shallow groundwater quality as a raw water source in Tambak Rejo Village, Waru District, Sidoarjo Regency. The study is motivated by indications of groundwater quality degradation, likely influenced by the proximity of wells to industrial wastewater discharge channels. A scoring method with the Sturges classification approach was applied to assess key chemical parameters, including pH, nitrate (NO₃⁻), nitrite (NO₂⁻), iron (Fe), and manganese (Mn), referring to the quality standards established by the Kementerian Kesehatan Republik Indonesia. Data were collected from six actively used dug wells. Water samples were analyzed in the laboratory and evaluated using a scoring method to determine groundwater feasibility. The results indicate that pH, nitrate, nitrite, and iron concentrations at all sampling points comply with the established standards. However, manganese (Mn) concentrations in three wells (wells 2, 3, and 6) exceed the permissible limits. Based on the scoring results, three wells are classified as feasible, while the remaining three are categorized as not feasible as raw water sources. In conclusion, groundwater quality in the study area has not fully met the required standards for raw water, primarily due to elevated manganese concentrations. Therefore, water treatment is necessary prior to use, along with improved environmental management to ensure sustainable groundwater quality.Keywords: Shallow groundwater, water quality, raw water, chemical parameters, Scoring Sturges, Sidoarjo.

Abstract

Abstract — Spring water, as part of groundwater resources, is widely utilized by communities for daily needs; therefore, its quality must comply with health standards. This study aims to assess the quality of spring water in Manisharjo Village, Ngrambe District, Ngawi Regency based on physical, chemical, and biological parameters and to determine water quality status using the STORET method. Samples were collected from three spring water sources that are still used by local residents. In-situ measurements were conducted for temperature, odor, taste, pH, and TDS, while ex-situ laboratory analyses were performed for hardness, detergent content, and Escherichia coli. The results were compared with Indonesian Ministry of Health Regulation No. 32 of 2017. STORET analysis shows that spring water source 1 obtained a score of -1 with a good to lightly polluted category, while sources 2 and 3 obtained scores of -14 and -17, both classified as lightly polluted. Overall, the decline in water quality is influenced by chemical and biological parameters that exceed allowable standards.

Abstract

Irrigation networks are essential infrastructures for supporting agricultural productivity, water distribution equity, and sustainable agricultural management. However, irrigation system performance is often affected by physical deterioration, limited operation and maintenance support, weak documentation, and institutional constraints. Objective: This study aims to evaluate the performance of the irrigation network in the Rejoso Irrigation Area, focusing on the Rejoso Kiri and Jati Secondary Canals, using the Irrigation System Performance Index (IKSI) method. Methodology: This research employed a descriptive quantitative approach through field surveys, direct observations, structured questionnaires, and secondary data collection from relevant agencies. Data were analyzed using the IKSI weighted scoring system, which assesses six main components: physical infrastructure, crop productivity, supporting facilities, organization and personnel, documentation, and the institutional condition of Water Users Associations (P3A). Findings: The results show that the overall IKSI value of the Rejoso Irrigation Area is 64.3%, which falls into the poor performance category and requires attention. The most critical aspects are related to physical infrastructure, supporting facilities, documentation, and P3A institutional performance. Implications: These findings imply that irrigation management improvement should not only focus on canal rehabilitation, but also on strengthening operation and maintenance facilities, improving documentation systems, and increasing P3A participation. Originality: The originality of this study lies in its location-specific evaluation of secondary canals by integrating technical, operational, and institutional aspects to provide targeted recommendations for improving irrigation system performance.
