Abstract

Climate change and land use change in the Lesti Sub-DAS increase the risk of flooding and land degradation, requiring reliable flow predictions to support water resource management. However, the performance of the NRECA model in predicting monthly flows in this region is still not optimal because calibration-validation strategies and the use of environmental parameters have not been systematically studied. This study optimizes the NRECA model to predict monthly discharge for the period 2011-2020 in the Lesti sub-watershed by calibrating the GWF and PSUB parameters based on rainfall, evapotranspiration, and watershed morphometry data in three data division scenarios (70:30, 80:20, and 90:10 for calibration:validation). The results show that all scenarios produce excellent performance with calibration Nash-Sutcliffe Efficiency (NSE) values between 0.99491-0.99561 and correlation coefficients (R) between 0.99746-0.99785, while validation yielded NSE values between 0.89112-0.97227 and R between 0.49959-0.81520. The best scenario was obtained with a combination of 8 years of calibration and 2 years of validation, with NSE = 0.99561 and R = 0.99785 at the calibration stage, and NSE = 0.97227 and R = 0.81512 at the validation stage, indicating the model's ability to consistently represent monthly discharge variations. The similarity between the model discharge pattern and observations during the base and peak flow periods indicates that GWF optimization specifically improves the representation of base flow response. This study contributes by presenting an optimization-based calibration-validation scheme for the NRECA model, which can be used as a reference in conservation planning and reservoir operation management in watersheds with limited data.

Abstract

Reliable precipitation data are essential for hydrological modeling in data-scarce basins. This study evaluates five statistical bias-correction methods—Correction Factor (mean-ratio scaling), Linear Scaling (mean adjustment), Linear Regression, Local Intensity Scaling (LOCI; wet-day threshold and intensity adjustment), and Power Transformation—to improve satellite rainfall for the Gembong Watershed, Pasuruan, East Java, Indonesia. We used daily TRMM (2004–2013) and GPM IMERG (2014–2023) estimates harmonized to a common grid and time step and compared them with gauges using Pearson’s r, Nash–Sutcliffe Efficiency (NSE), and the RMSE-observation standard deviation ratio (RSR). LOCI delivered the best overall balance (NSE = 0.92; r = 0.84; RSR = 0.55), while Linear Scaling achieved a slightly lower NSE but the smallest RSR (NSE = 0.87; RSR = 0.49). Power Transformation showed limited skill (NSE = 0.57; RSR = 0.90) despite high correlation. Ranking prioritized NSE with r and RSR as supporting metrics. The coastal-lowland setting of Pasuruan—with strong convective rainfall and heterogeneous land use—makes accurate bias correction particularly consequential for flood and water-resources analysis. We conclude that LOCI’s adaptive thresholding is well-suited to such regimes and that the comparative framework aids method selection for similar data-scarce watersheds.

Abstract

Reliable raw water service depends on asset condition, institutional capability, and watershed context; existing checklists in Indonesia fail to produce a validated, decision-ready performance score.  This study develops a composite performance indicator for raw water infrastructure that incorporates technical (Tk), institutional/non-technical (NT), and environmental (Li) dimensions. Data were collected from 21 schemes in Lombok–Sumbawa, West Nusa Tenggara Province, Indonesia (NTB), with 160 respondents, using field assessments and 1–4 scale questionnaires. Estimated reflective formative partial least squares structural equation modeling was then applied, and GRG calibration was used to minimize deviation from field scores under non-negativity and unit sum constraints for interpretability and portability. All pillars contribute positively and significantly to the composite index, which exhibits high explanatory power (R² = 0.997). The calibrated index is PIRWSS = 0.440 PITk + 0.340 PINT + 0.220 PILi, with SSR ≈ 83.412, RMSE ≈ 0.522, MSE ≈ 5.721, and ≈ 99.70% accuracy relative to field benchmarks. A cross-site analysis shows higher performance in Lombok than in Sumbawa, reflecting hydroclimatic conditions and conveyance configurations. The index provides utilities and regulators with a transparent, reproducible framework for benchmarking and prioritizing operations, maintenance, rehabilitation, and source water protection

Abstract

The transformation of rain to discharge is a modeling process that converts rain data into discharge data. Discharge data in a watershed (DAS) is needed to determine the availability of water discharge in a river that will be used to meet the needs of living things around it. However, the availability of river flow data is often incomplete. Therefore, a change in the variety of rain to discharge is needed. This study aims to determine the results of the calculation of the conversion of rainfall into discharge at the Welang watershed location, Pasuruan Regency. The method used is the FJ. Mock and NRECA methods. The calculation results from these two methods will be compared with the AWLR data in the Welang watershed. From the results of the analysis, it was found that the most suitable method for calculating the transfer of rainfall into discharge in the Welang watershed is the FJ. Mock method with an NSE value of 0.629, a PBIAS value of 0.437, and a correlation coefficient (R) of 0.793. The use of the surrounding land influences the discharge condition in a watershed. The relationship between changes in land use and the condition of the annual average discharge of the Welang watershed shows that the discharge value tends to decrease in terms of comparisons in 2006, 2010, 2015, and 2020. Alih ragam hujan menjadi debit merupakan proses permodelan yang mengubah data hujan menjadi data debit. Data debit pada suatu daerah aliran sungai (DAS) diperlukan untuk mengetahui ketersediaan debit air pada suatu sungai yang akan dipergunakan untuk memenuhi kebutuhan makhluk hidup disekitarnya. Tapi pada kenyataannya ketersediaan data debit aliran sungai sering kali tidak lengkap, Maka dari itu dibutuhkan suatu alih ragam hujan menjadi debit. Pada studi ini bertujuan untuk mengetahui hasil perhitungan alih ragam hujan menjadi debit pada lokasi DAS Welang, Kabupaten Pasuruan. Metode yang digunakan adalah metode FJ. Mock dan NRECA. Hasil perhitungan dari kedua metode tersebut nantinya dibandingkan dengan data AWLR pada DAS Welang. Dari hasil analisis didapatkan bahwa metode yang paling sesuai untuk perhitungan alih ragam hujan menjadi debit pada DAS Welang adalah metode FJ. Mock dengan nilai NSE sebesar 0,629, nilai PBIAS sebesar 0,437 dan nilai koefisien korelasi (R) sebesar 0,793. Kondisi debit pada suatu DAS dipengaruhi oleh penggunaan lahan disekitarnya. Hubungan antara perubahan tata guna lahan dengan kondisi debit rerata tahunan DAS Welang menunjukkan nilai debit yang cenderung menurun, ditinjau dari perbandingan tahun 2006, 2010, 2015 dan 2020.

Abstract

Hydrological analysis is a basis for water building planning. However, the problem in hydrological analysis usually in the availability of data, such as empty/incomplete rain data, inadequate rain stations, rain recording which is still done manually so that it can increase the risk errors. To overcome the problem of the lack of availability of rain data, the alternative that can be used is using satellite rainfall. Satellite rainfall is using remote sensing technology, so it is possible to get wider area coverage, near real time data, fast and free access and economical. This study was include for calibration and validation of uncorrected satellite rainfall data in the Sadar watershed area, Mojokerto Regency and using two types of satellites, TRMM and CHIRPS. The data validation analysis methods used are Nash-Sutcliffe Efficiency (NSE), Correlation Coefficient (R), and Root Mean Squared Error-observations standard deviation ratio (RSR). The results of the validation of the TRMM and CHIRPS satellite rainfall data show that the TRMM satellite has the suitability of the field data by 70,3% while the CHIRPS satellite has the suitability of the field data by 20,7%. So, from the overall analysis can be concluded that TRMM data can be recommended as an alternative hydrology data in the Sadar watershed.Analisis hidrologi adalah suatu dasar perencanaan bangunan air. Namun, permasalahan dalam analisis hidrologi biasanya terletak pada ketersediaan data yang kurang memadai, contoh seperti data hujan yang kosong/tidak lengkap, stasiun hujan yang tidak memadai, pencatatan hujan yang masih dilakukan secara manual sehingga dapat meningkatkan risiko kesalahan pencatatan. Untuk mengatasi permasalahan tentang minimnya ketersediaan data hujan, maka alternatif yang dapat digunakan adalah menggunakan curah hujan satelit. Curah hujan satelit yang menggunakan teknologi penginderaan jauh, sehingga cakupan wilayah luas, data near real time, akses cepat dan gratis serta ekonomis. Studi ini dilakukan untuk kalibrasi dan validasi terhadap curah hujan satelit belum terkoreksi pada wilayah DAS Sadar, Kabupaten Mojokerto dan menggunakan dua jenis satelit yaitu TRMM dan CHIRPS. Metode analisis validasi data yang digunakan berupa Nash-Sutcliffe Efficiency (NSE), Koefisien Korelasi (R), dan Root Mean Squared Error- observations standard deviation ratio (RSR). Berdasarkan hasil perhitungan satelit TRMM menunjukan kesesuaian data dengan data lapangan sebesar 70,3%, sedangkan untuk satelit CHIRPS menunjukan kesesuaian data dengan data lapangan sebesar 20,7%, sehingga dapat disimpulkan TRMM dapat direkomendasikan menjadi data alternatif hidrologi

Abstract

Seawater intrusion and declining groundwater quality in coastal Lovina require more than purely technical responses that contribute to cultivating environmental values and the character of local communities. This paper describes a community-based education design for groundwater conservation through an infiltration-well siting plan and a pilot biopore installation in Kalibukbuk Village, Buleleng, Bali. We employed a participatory community service approach that integrated stakeholder coordination and interactive discussions with village authorities, community leaders, residents, and managers in charge of public facilities. Field observations were also performed to validate local constraints and opportunities for infiltration. Inputs from these discussions were synthesized into a context-based siting plan, which then guided the installation of four pilot biopores in a public area. The program was evaluated qualitatively using participatory observation and structured feedback collected during coordination meetings, site visits, and implementation activities. Results include an initial technical planning package identifying potential locations for infiltration wells and biopores, successful installation of four pilot biopores, and early indications of strengthened daily practices aligned with environmental character, such as organic-waste segregation for composting and improved groundwater-conservation literacy. These findings suggest that value education linked to tangible conservation actions can enhance community readiness for more sustainable groundwater management in coastal settings.

Abstract

This study analyzes land use and land cover (LULC) changes in the Banjir Kanal Timur Watershed, Semarang City, from 2004 to 2024, utilizing multi-temporal Landsat data and GIS-based supervised classification methods. This research focuses on a medium-sized tropical coastal city in Indonesia that has received little attention in previous LULC studies, particularly over a two-decade period. The East Flood Canal was selected because of its strategic role and vulnerability to unregulated land-use change, making it an ideal case study to assess the impacts of urban sprawl. The primary objective is to assess the extent of urban growth and its effects on natural land cover, particularly forested areas, water bodies, and brushwood. Using Landsat 7, 8, and 9 satellite imagery, this study applied supervised classification to categorize land cover types and evaluate spatial changes over time. The results indicate a substantial increase in urban and built-up land, from 49.63% in 2004 to 80.57% in 2024, accompanied by a drastic decline in forest cover, from 40.69% to 12.13%, highlighting rapid urbanization and environmental degradation. The classification reliability was validated using a confusion matrix, with overall accuracy exceeding 90% and Kappa statistics ranging from 0.852 to 0.869, indicating substantial to almost perfect agreement. These findings underscore the urgent need for sustainable urban planning, as continued land conversion may lead to increased flood risks, biodiversity loss, and reduced water retention capacity. This research demonstrates the effectiveness of remote sensing in monitoring land use dynamics and offers vital insights for policymakers to create balanced strategies between development and environmental preservation in Semarang City.

Abstract

Merak Port Berth VII is exposed to wave action, seismic loading, and soft-soil conditions, while retrofit works must be planned under limited marine access and a constrained schedule. This study verifies a hybrid wave-damping system comprising a platform-mounted wavescreen and a causeway revetment to improve multi-hazard resilience. Wind data from 2010–2022 were used for wave hindcasting to derive return-period wave conditions, while seismic actions and structural checks were evaluated using Indonesian and international port design criteria. Platform performance was assessed at the ultimate and serviceability limit states, and revetment stability was analyzed using the Morgenstern–Price method. Under the 500-year design combination, the platform satisfied strength and serviceability requirements, with vertical bearing safety factors of 3.40 and 3.53 based on SNI and UFC combinations, respectively, and deformations within operational limits. The revetment achieved a factor of safety of 1.49 under the same demand but became inadequate under the 1,000-year scenario, indicating the need for strengthening when higher reliability is required. The estimated construction cost is IDR 132,205,000,000, with an estimated duration of approximately 216 working days. This verification framework is transferable to brownfield Indonesian ports exposed to combined coastal and seismic hazards.

Abstract

Limited access to adequate bathing, washing, and toilet facilities (MCK) remains a significant problem for residents of RT-03/RW-10, Polaman Sub-Village, Kalirejo Village, Lawang District, Malang Regency, so that some residents still use the river to meet their basic sanitation needs, potentially reducing their health and environmental quality. This Community Service Activity aims to provide simple WASH facilities that meet sanitation standards while promoting behavioral changes toward clean and healthy living through community participation. The implementation methods included an initial survey and interviews to identify the socio-cultural and environmental conditions, discussions to develop solutions with the RT administrators and residents, socialization with the PKK women's group, the construction of the MCK through the self-help efforts of students, donors, and the community during July-October 2025, and an evaluation in November 2025 through field observations, interviews, and documentation. The results of the activity include the construction of a simple, functional, and easy-to-operate toilet two units with a layout that meets comfort standards and better manages wastewater flow; increased community understanding of the importance of sanitation and environmental conservation; and a stronger spirit of cooperation in maintaining shared facilities. Overall, this program was deemed effective by residents and neighborhood association administrators in improving access to basic sanitation, reducing dependence on rivers as a means of sanitation, and supporting the creation of a cleaner, healthier, and more sustainable residential environment, while also providing a model for simple sanitation facilities that can be replicated in similar areas.
