<![CDATA[Flooding is an event that occurs when water inundates dry land or when a river's flow exceeds its capacity. According to the National Disaster Management Agency (BNPB), in 2021, flooding occurred in Tapin, triggered by heavy rainfall. To analyze the river’s capacity to handle floods, it is necessary to use hydraulic modeling through the HEC-RAS application, which provides insight into the river's ability to accommodate floods, particularly after the construction of the Tapin Dam. This study aims to analyze the flood discharge volume based on hydraulic analysis using HEC-RAS 5.0.7. The study uses secondary data, including Digital Elevation Model (DEM) data, Global Precipitation Measurement (GPM) satellite rainfall data, and Cross Section data. The method used for the calculation analysis is the Nakayasu Synthetic Unit Hydrograph method. Based on the hydraulic analysis results, the maximum flood discharge before the Tapin Dam construction, for return periods ranging from 2 to 100 years, is between 202.07 m³/s and 520.13 m³/s. Meanwhile, after the construction of the Tapin Dam, the maximum flood discharge for the same return periods is between 147.15 m³/s and 316.69 m³/s.]]>

<![CDATA[Wetland irrigation areas require good monitoring of discharge and water levels. Water level analysis can be done using software, for example, HEC RAS. The research analyzes the actual discharge and water surface elevation in the Tabuk River Irrigation Wetland Area. The data analysis process includes hydrological and hydraulic analysis. The research uses geometric ditch data as primary data, including channel cross-section and channel velocity. Daily rainfall is used as secondary data to analyze the hydrology part. Simulation results using steady flow conditions show variations in water level at each measurement station. The simulated water level is close to existing conditions at STA 0+500 and STA 1+500, with 15% and 17% error values, respectively. However, at STA 0+000 and STA 1+000, there are significant differences with differences of up to 70% and 160%. The significantly different results could be due to the influence of the accuracy of the channel geometry data]]>

<![CDATA[Student commuting to the Unesa Ketintang Campus often causes traffic congestion due to the dominance of private vehicles and underutilized public transportation. This study aims to determine the optimal route for the Wirawiri FD09 feeder bus and strategic stop locations through Origin-Destination Matrix and GIS-based Multi Criteria Analysis. A quantitative descriptive-analytical approach with spatial analysis using QGIS was employed to analyze travel patterns, demand potential, and service accessibility. The results indicate that 67% of respondents (254 students) are willing to shift to the feeder service if the route enters the campus and stops are located near faculties. Based on spatial analysis with a 300–400meter walking radius, this study recommends adjusting alternative routes into the campus and establishing four new stops: the Informatics Engineering, Tennis Court, Faculty of Economics and Business, and Front Gate stops. The application of QGIS effectively provides measurable, data-driven spatial recommendations. These route and stop adjustments are expected to enhance academic mobility efficiency and support sustainable urban transportation systems.]]>

<![CDATA[Coal distribution at PT Bukit Asam uses railway transportation. This is considered quite efficient given the capability of trains to carry both passengers and goods in large quantities in a single trip, making it very efficient for mass transportation and logistics distribution over medium to long distances. However, in terms of advantages, trains on a single track face limitations in distance, load, and traffic capacity. Planning a Double Track route offers advantages in addressing issues related to load and traffic capacity. This study aims to find solutions regarding the traffic load on a track by adding a railway line (Double Track) without changing the existing track. The railway route planning is designed based on factors of comfort, safety, security, economy, and environment. The Vertical Alignment planning includes 2 curves with a planned radius of 7000 m and a gradient value of 6.6‰. The material requirements for the planned railway structure consist of R60 Rails (497 units), Double Elastic Fasteners (41,400 units), Concrete Sleepers (10,350 units), Ballast Volume (7,173 ), Ballast Volume (15,897 ), Cut Volume (567,743 ), and Fill Volume (205,269 ) ]]>

<![CDATA[The purpose of this study wa to examine the effect of varying the binder ratio between fly ash and metakaolin on the compressive strength of geopolymer mortar, as well as to determine the optimum binder mixture composition that would yield the highest compressive strength at room temperature curing. Thi study uses a quantitative approach with laboratory experiments, using variations in the fly ash : metakolin binder ratio, namely 100% : 0%, 70% : 30%, 50% : 50%, 30% : 70% and 0% : 100%, as well as 8 M NaOH and Na2SiO3 activator solutions using a sand : binder ratio of 2,5 : 1. Sixty 5×5×5 cm2 cube shaped test specimens were then tested for compressive strength. This study proves that the combination of fly ash and metakaolin increases the strength of geopolymer mortar. The mixture of 70% fly ash : 30% metakaolin produced the most optimal compressive strength at 28 days, indicating that the reactivity of metakaolin and the aluminosilicate content in fly ash can enhance the geopolymerization prosess and make the microstructure of the mortar more compact. This study proves combining fly ash and metakaolin be more environmentally friendly alternative to portland cement while maintaining its mechanical strength.]]>

<![CDATA[The demand for adequate housing in Indonesia continues to increase along with population growth and changes in community lifestyles. However, the provision of housing infrastructure and facilities still faces various challenges that affect housing quality. This study aims to analyze residents’ satisfaction with building physical conditions and public facilities in Green Semanggi Mangrove Housing using the Importance–Performance Analysis (IPA) method. The data were collected through a Likert-scale questionnaire distributed to 106 respondents. The results indicate that the average level of conformity between performance and importance reached 84.05%, suggesting that, in general, the condition of facilities and buildings has fairly met residents’ expectations. Nevertheless, several attributes still require special attention. Based on the Cartesian diagram analysis, in-house sanitation, including the functionality of toilets and sinks as well as the absence of unpleasant odors, falls into the main priority quadrant. This finding indicates a gap between the level of importance and performance for this attribute. Therefore, improvements are necessary through enhancing ventilation systems, repairing plumbing and drainage installations, installing standard water traps, and conducting routine maintenance to improve comfort and ensure the sustainability of housing quality. Keywords: building physical condition, public housing facilities, importance performance analysis (IPA)]]>
