Abstract

Maximizing the absorption of water into the soil to reduce puddles in developing areas can be done by using porous paving blocks as cover for soil reports with water escape capabilities. Paving block porous materials need to be considered qualified quality according to their use. Fly ash as one of the coal-burning wastes can be used as a substitution material for cement. Zeolite instead of gravel is a source of considerable mining material, structured hydrate aluminum silicate with a high specific surface area and has a great potential for use as an absorbent material that can pass through water. This study investigates the use of fly ash as substitute of cement and zeolite as aggregates in porous paving block. Theresearch aims to identify optimal composition of fly ash and zeolite for achieving desirable compressive strength and infiltration. Porous paving block were manufacture using ratio 1 (segment): 4 (grains) of binder to aggregate. Fly ash waste used in a mixture of porous paving block materials varies by 10%, 20%, 30% and 40% using rough aggregates of zeolite. Compressive strength tests are performed at 7 days, 14 days and 28 days and for infiltration tests at 28 days. Research showed compressive strength values of 31.40 MPa, 36.75 MPa, 37.50 MPa, 32.42 MPa, and 32.67 MPa, respectively, can be used as a parakeet cover layer. The infiltration coefficients are 0.0611 cm/s, 0.4376 cm/s, 0.1218 cm/s, 0.0621 cm/s and 0.1012 cm/s, respectively, which are capable of passing water from the surface to the ground. This study highlights the potential of utilizing waste material fly ash and zeolite in quality of porous paving blocks, contributing to sustainable construction and stormwater management in urban areas.

Abstract

The occurrence of earthquakes is frequent in Indonesia due to its position in a highly active tectonic zone. One approach to improve the seismic performance of existing buildings is through the use of base isolation. The concept of using base isolation systems aims to increase the natural period of structures and provide additional damping to reduce seismic forces on the structures. A comparative study was performed between a fixed base system and base isolated system in a 13-story reinforced concrete building located in Surabaya on soft soil. Subsequently, these models were evaluated for their structural response using the nonlinear time history analysis. The results demonstrate that the use of base isolation systems can significantly elongate the building’s natural period, resulting in a significant decrease in the base shear, acceleration response, drift, and the plastic hinge formed. This study proves that this technology is suitable to be applied to existing buildings with satisfactory results.

Abstract

Optimal management of irrigation water allocation is an important challenge especially in areas with limited resources. The Analytical Hierarchy Process (AHP) method can be used as a tool in complex decision-making by considering various factors that affect water allocation. In this study, AHP is applied to address the gaps in the e-Paksi program that uses individual judgement, which applied a subjective norm values. This study seeks to achieve balanced water allocation priorities using that approach, reflecting the existing physical conditions and social interests of the community, as represented by the assessment of field practitioners. The criteria used in the AHP analysis include Physical Structure, Crop Productivity, Supporting Facilities, Organisation Personnel, Documentation, and Water User Farmers, derived from e-Paksi. The case study was conducted in the SIM Irrigation Area (D.I.), with secondary alternatives including Sumber Batang, Purwodadi, Ngabean, Bedilan, Karang, and Ulo. The results show that the highest irrigation allocation priority is given to Karang secondary with a priority value of 0.1735. The condition of Karang secondary based on UPI BBWS BS has an average value of 3.83 on a scale of 1 to 5. Integration of AHP approach with e-Paksi value criteria provides more comprehensive results for decision making in fair and appropriate irrigation water allocation.

Abstract

Flood mapping is critical to strengthen urban resilience, particularly in Surabaya,where flooding is a major and recurring threat. Sentinel-1 satellite data offerssignificant advantages for flood model calibration due to its high-resolution imageryand frequent revisits. This study utilizes Google Earth Engine to process and analyseSentinel-1 data for mapping flood extents using two different polarizations: VV andVH. The research compares the capabilities of these polarizations in detecting floodareas. The results show that VV polarization consistently identifies a larger flood areacompared to VH polarization under similar processing conditions. However, theKappa coefficient was used to assess classification accuracy, with VV achieving aKappa of 0.8 and VH reaching a higher Kappa of 0.92, reflecting better classificationperformance. These findings suggest that while VV provides a broader flooddetection, VH offers more reliable flood mapping, highlighting the trade-offs betweensensitivity and accuracy in flood monitoring using Sentinel-1 satellite.

Abstract

Timeliness, fast execution, and effectiveness in freight transport are the reasons why freight trains are the preferred mode of transportation for many manufacturing companies. To Developed of the railway utilization for freight transport, the Indonesian government has implemented policies, including the integration of the railroad junction with JIIPE (Java Integrated Industrial and Ports Estate) along the main line of the North Java Railroad (PP 71 2021). However, the growing number of trains originating from the junction poses challenges to existing schedules, particularly impacting the Surabaya Pasarturi - Bojonegoro railroad segment. This study aims to calculate train schedule based on headway and capacity, proposing adjustments to the departure frequency at Duduk Station in line with the train timetable (Gapeka) 2021 for the Surabaya Pasarturi - Bojonegoro Segment 12 of 17 alternative trains per day west direction and 18 of 21 alternative trains per day east direction. It is essential to note that this proposed frequency exceeds theoretical capacity, emphasizing the need for careful planning of additional trains within the constraints of capacity theory to maintain operational efficiency.

Abstract

Earthquakes are devastating natural events that can cause substantial structuraldamage, often resulting in collapses due to inadequate seismic design. This studyinvestigates the effectiveness of two seismic protection systems: fluid viscousdamper (FVD) and lead rubber bearing (LRB) isolation, in improving the seismicperformance of a structure. The initial research did not include any base isolatoror link damper for earthquake protection. The results were then compared to asimilar investigation of the same structure using FVD and LRB isolation.Significant differences in structural behavior were observed, with both systemsdemonstrating improved performance in mitigating seismic forces. The findingshighlight the importance of incorporating advanced damping mechanisms, suchas FVD and LRB, in building design to enhance earthquake resilience in proneregions. This study underscores the critical need for integrating such seismicprotection systems to reduce structural damage and improve safety duringearthquakes.

Abstract

Manikin watershed is located in Kuaklalo Village which borders Bokong Village, Taebenu Subdistrict, Kupang Regency, East Nusa Tenggara Province which has an area of 49.31 km2 with a river length of 8.62 km which has a semi-arid climate with a fairly high annual rainfall of around 1000 - 1500 mm. This study aims to compare the design flood discharge and peak hour with Nakayasu Synthetic Unit Hydrograph (HSS) method, GAMA I, HEC-HMS and rainfall discharge model with HEC_RAS 2D in Manikin Dam watershed. In this study, 6-hour rainfall witha return period of 50 years and 100 years was used. Based on the analysis results, the calculation of the hydrological numerical model flood discharge with the HEC-HMS method with a return period of 50 years and 100 years is 511.90 m³/s and 599.30 m³/s with a peak time at the 4th hour. The peak discharge valuesobtained using the Nakayasu Synthetic Unit Hydrograph and GAMA I methods with a return period of 50 years and 100 years are 342.11 m³/s, 381.14 m³/s and 406.44 m³/s, 456.13 m³/s, and the peak time obtained at SUH Nakayasu is 3 hours and GAMA I is 4 hours. Numerical model results with HEC-RAS 2D v6.6 with 6hours of rainfall on the grid obtained peak discharge Hydrograph values for the 50-year and 100-year return periods of 494.86 m³/s and 604.88 m³/s, with the peak time at the 5th hour. Therefore, the largest peak discharge and peak time results were obtained from the HEC-HMS method among the three SUH formulas and HEC-RAS calculations

Abstract

In half-through bridge or pony steel bridge, that is a bridge without upper windbracing, strength of the bridge is determined mainly by the lateral bucklingstrength of its upper chord. Buckling strength of this chord is provided by theflexural stiffness of vertical web member, cross beam, and diagonal beam. In orderto improve the stiffness of vertical web member, triangular steel profile that wasquite high was added to the inner side of bridge for reducing the clearance widthin bridge and disturbing traffic or pedestrian. In this research, stiffness of thevertical web member was improved by using the non-prismatic cross section andadding the triangular stiffener as high as the concrete deck. Finite ElementAnalysis for the lateral stiffness of bridge cross section used a 3D element modelwhich has been validated by previous study. This numerical study was conductedto validate the Engesser theory for determining the lateral elastic stiffness fromupper chord. Study shows the result that accuracy of 3D element model isextremely high, compared with analytic method. Lateral elastic stiffness of bridgein general increased along with the stiffness of vertical web member. However, itcan be concluded that effect on the capability of lateral buckling in upper chordwas not too significant, as a consequence of the increase in stiffness of verticalweb member. Critical lateral buckling occurred in an inelastic range, in which thecritical inelastic buckling stress was determined using small tangent modulus asalternative of modulus of elasticity.
