Abstract

Natural and artificial rivers contain bed-load sediment materials with varying shapes and grain sizes influencing flow resistance, velocity, and discharge. This resistance is expressed by the Manning roughness coefficient (n), whose accurate estimation is essential for hydraulic analysis. While n is commonly obtained from Manning’s table, alternative methods based on hydraulic parameters, channel geometry, and sediment characteristics, such as the Keulegan, Mayer-Peter-Muller, Lane and Carlson, Henderson, Raudkivi, Subramanya, and Wong and Parker methods, can be applied for more site-specific estimations. This study utilized primary field data and secondary data to estimate n values using various approaches. The n values ranged from 0.096–0.148 (hydraulic parameters), 0.069–0.136 (channel geometry), and 0.009–0.018 (sediment-based methods). Error analysis comparing calculated and observed discharges showed that the channel geometry method yielded the most accurate results with an average error of 15.59%. In contrast, other methods resulted in significantly higher errors. Thus, the channel geometry approach is recommended for estimating the Manning coefficient in the Way Tapus River.

Abstract

Post-earthquake housing reconstruction is essential for accelerating community recovery and ensuring safer living conditions in disaster-prone regions. This study evaluates the potential of recycled rubble sand from demolished masonry walls as an acceptable aggregate replacement in mortar production. It explores its integration into the development of a Healthy Simple House (HSH) model for post-disaster housing reconstruction. Laboratory experiments were conducted in accordance with PUBI-1982 and SII 0052-80 standards to characterize material properties and assess mechanical performance. The results indicate that rubble sand exhibits a well-graded particle distribution, stable density values (SSD 2.48 g/cm³, bulk 2.35 g/cm³, apparent 2.71 g/cm³), and moderate water absorption (5.62%), with slight organic contamination. Compressive strength tests showed that mortars with a 1:3 cement-to-sand ratio reached approximately 24 MPa at 28 days, meeting structural requirements, while higher rubble proportions reduced strength, restricting their application to non-structural components. The incorporation of rubble sand into the HSH model highlights its role in sustainable reconstruction by reducing reliance on natural resources while ensuring safe, healthy, and affordable housing. The study concludes that recycled rubble sand can be effectively utilized as a partial aggregate substitute, providing practical guidance for post-disaster housing programs and informing policy development for environmentally friendly and resilient reconstruction strategies that contribute to community resilience.

Abstract

Hydraulic resistance, represented by the Chezy coefficient, is crucial in estimating flow discharge in open channels and serves as a fundamental parameter in designing hydraulic structures such as irrigation canals and river control facilities. This study investigates the behavior of the Chezy coefficient under non-sediment-laden (NSL) and sediment-laden (SL) flow conditions through controlled laboratory experiments using coarse sand, complemented by comparative analysis with data from irrigation channels and natural rivers. The results show that the ratio of mean velocity to shear velocity (U/u*) exhibits a robust correlation with discharge (Q) under both flow conditions, with a determination coefficient (R²) exceeding 0.96. The hydraulic radius (Rh) also shows a strong linear relationship with discharge (R ≈ 0.98), confirming its role in the empirical estimation of the Chezy coefficient (C). The value of C increases with higher velocity ratios but tends to be slightly lower under SL conditions due to increased resistance from suspended sediments. The Mean Absolute Error (MAE) value of 0.02 indicates a slight difference between NSL and SL conditions. These findings suggest that the empirical method is unreliable and exhibits significant differences in estimating Chezy under sediment-laden flow. It highlights the need for supplementary approaches to improve irrigation and river management design accuracy.

Abstract

Ponds are key structures in flood control strategies, especially in industrial areas which have a high vulnerability to excess air runoff. The main risk faced is the potential for air overflow from the pond, which could cause serious damage downstream, including the risk of embankment failure and damage to the spillway. Therefore, controlling the water level in the pond is very important, especially in dealing with high-intensity flooding events. When the water level reaches the specified threshold, the water in the pool must flow in a controlled to the drainage channel through the spillway. This research uses the HSS Nakayasu method to estimate flood discharge entering the pond. At the same time, the calculation of the spillway is carried out based on the reservoir capacity of the pond and the planned spillway design. The research results show that the flood discharge entering the pond at various return periods, namely 5, 10, 20, 25, 50, and 100 years, ranges from 19.53 m³/s to 33.78 m³/s. The discharge from the spillway varies from 5,03 m³/s to 8,68 m³/s at the same return period. The maximum flood water level above the spillway varies from 0,90 m to 1.30 m, with the increase in water level from the bottom of the pond (elevation +20.00 m) reaching +24.90 m to +25.30 m. Further calculation results show that at a return period of 100 years, the pond is able to reduce flood discharge by up to 74%, with 26% of the flood discharge being channeled gradually through spillways and drainage channels to the river. The effectiveness of the spillway in reducing the risk of runoff confirms that this pond functions as a reliable flood mitigation solution for the shoe factory industrial area in Pekalongan Regency, Central Java Province.

Abstract

Industri konstruksi seperti batching plant dan Asphalt Mixing Plant (AMP) menghasilkan limbah berupa sisa beton mengeras, slurry pencucian mixer, agregat terkontaminasi semen, serta residu aspal halus yang berpotensi menimbulkan dampak lingkungan apabila tidak dikelola dan dimanfaatkan secara optimal. Kegiatan pengabdian kepada masyarakat ini bertujuan mendukung penerapan infrastruktur berkelanjutan melalui optimalisasi pemanfaatan limbah konstruksi sebagai bahan baku alternatif beton non-struktural. Program dilaksanakan melalui tahapan identifikasi jenis dan volume limbah (±1–2 ton per minggu), pengolahan awal (pengeringan, penghancuran, dan pengayakan), perancangan komposisi campuran (mix design), pencetakan produk, curing selama 28 hari, serta pengujian kuat tekan dan daya serap air. Hasil perancangan menghasilkan batako berdimensi 40 × 20 × 10 cm, paving block 20 × 10 × 6 cm, serta saluran beton pracetak dengan lebar 40–85 cm dan tinggi 45–60 cm. Secara teknis, agregat limbah batching plant efektif sebagai substitusi parsial agregat alami, sedangkan residu AMP berfungsi sebagai filler yang meningkatkan kepadatan dan menurunkan porositas beton. Produk yang dihasilkan memenuhi kriteria mutu beton non-struktural untuk aplikasi pagar, perkerasan pejalan kaki, dan saluran drainase kawasan industri skala kecil–menengah maupun saluran irigasi. Kegiatan ini berkontribusi pada pengurangan timbulan limbah, efisiensi biaya material, serta penguatan prinsip ekonomi sirkular dalam pembangunan infrastruktur berkelanjutan.

Abstract

The development of industrial areas significantly increases surface runoff by expanding impervious surfaces, potentially exceeding the capacity of existing drainage systems and increasing flood risk. In many industrial zones, stormwater management infrastructure must also accommodate additional discharge from retention pond spillways, which can further burden road drainage systems. In the study area, spillway outflow from a retention pond is conveyed into the road drainage network, requiring an adequately designed culvert system to accommodate the flow safely. This study aims to analyze the hydraulic capacity and design an appropriate road culvert drainage system to convey spillway outflow in an industrial area. Secondary data on design flood discharge were obtained from previous studies that conducted rainfall frequency analysis, flood discharge estimation using the Nakayasu Synthetic Unit Hydrograph method, and spillway routing analysis. The results show that the design flood discharge for the 100-year return period (Q100) is 8.68 m³/s. A hydraulic analysis using the Manning equation was performed to determine the culvert dimensions required to convey the design discharge safely. The analysis indicates that the proposed culvert system is hydraulically adequate. A culvert with a diameter of 2.0 m is installed in the upstream section to accommodate concentrated inflow from the spillway outlet. In comparison, two parallel culverts with a diameter of 1.3 m are installed along the middle-to-downstream sections on both sides of the road. This configuration provides a total discharge capacity of 8.752 m³/s, exceeding the design flood discharge. The results demonstrate that the proposed design improves drainage Reliability in industrial areas and contributes to flood mitigation by regulating runoff discharge, thereby reducing potential flood risk in downstream residential areas. These findings provide practical guidance for infrastructure planning and policy strategies to integrate industrial drainage systems with regional flood mitigation efforts.
