Abstract

Expansive clays is one of the problematic soils which cause numerous problems in pavement engineering and construction such as on airports, highways and roads. Although cement is widely used commonly perceived as the most conventional materials used in treating expansive soils in geotechnical and geoenvironmental engineering applications, of treating expansive soils the increasing trend of cement production has resulted in considerable environmental issues like raising the greenhouse gas emission. The present investigation aims at documenting the effect of adding zeolite a natural pozzolans as a supplementary cementitious material - on the mechanical and physical behaviour of cement stabilized expansive soil mixture. Specifically the Influence of cement-zeolite ratio and level. Soil samples for testing consisted of two different mixtures, namely Clay Soil with 15% bentonite addition and Clay Soil without bentonite addition, each with five binder contents (5%, 7%,10%, 12%, 14%) and various cement to zeolite ratios (5:0; 7:0; 5:5; 7:3; 5:7; 7:5; 5:9; 7:7) were prepared for experimentation. Tests conducted on all soil mixture samples, namely Compaction Test, CBR and UCS revealed that the effectiveness of adding zeolite on the strength of expansive clay soil mixtures is at cement-zeolite percentages of 10%; 12% and 14%, at all cement-zeolite ratios.

Abstract

The Tempuran Dam is one of the oldest dams in Indonesia and is currently experiencing a lot of damage, which could potentially lead to dam failure such as a dam collapse. To reduce the impact of losses resulting from dam collapses, it is necessary to analyze flood inundation patterns in the context of disaster mitigation. The dam failure analysis was modeled using HEC-RAS software with failure conditions due to overtopping and due to piping. The input in this modeling is the PMF plan discharge which is generated using HEC-HMS modeling with the HSS SCS method. The data required for HEC-HMS modeling are raster maps, land use maps, soil type maps and Hersfield method PMP rainfall plans. From the analysis results, it was found that the PMF planned flood was 115.54 m3/sec. The area of the flood inundation due to the collapse of the Tempuran Dam, the bottom piping condition was 2.61 km2 and the depth of the flood varied between 0 m to 3 m, where the area most deeply affected by the inundation was Purwosari Village, Blora Kota District. From the mapping results, the areas affected by flood inundation due to the collapse of the Tempuran Dam are Tempuran Village, Sendangharjo Village, Ngadipurwo Village, Purwosari Village, Patalan Village and Tempurejo Village. Where the fastest flood travel time is 48 minutes to Tempuran Village and the longest flood travel time is 5.25 hours to Tempurejo Village.

Abstract

Road infrastructure is an important element that must be well planned where in its implementation it is faced with limited resources. Therefore, traffic surveys conducted for a full year to obtain the Average Annual Daily Traffic (AADT) value used in road planning and design are difficult to obtain. To overcome these obstacles, the government has set the number of survey days for two days and seven days depending on its designation. This study aims to determine the error in estimating the Average Daily Traffic (ADT) based on the number of survey days. Data were obtained through field surveys using an automatic vehicle counter with a tool error value of 10%. The errors calculated include MAE, MAPE, RMSE, and Bias. The results of the study show that the number of survey days affects the magnitude of the error and the range of ADT Bias in predicting the AADT value. The number of survey days for two days, three days, and seven days showed good predictions. The Bias Range as a correction factor for the estimated AADT value is influenced by traffic conditions during the year. The correction factor with 95% CI based on the recommended research results for Road Type 4/2T or 2/1 is in the interval (1.40;-1.59) for a 2-day survey, and (3.92;1.17) for a 7-day survey.

Abstract

Demand forecasting is used by airlines to predict the travel behavior of potential passengers. Accurate forecasting is critical to the overall success of an airline. An important element in forecasting is passenger volume estimation. The goal is to predict the number of passengers expected between two cities for a given time interval. Based on this forecast, airlines can make decisions about new routes or additional flights on existing routes. Starting January 2020, all flights to Yogyakarta have landed at Yogyakarta International Airport (YIA) except for flights using propeller aircraft such as ATR which can still use Adisutjipto International Airport (JOG). Adisutjipto International Airport currently only serves 3 routes, namely Yogyakarta (JOG) - Jakarta (HLP) RT., Yogyakarta (JOG) - Bandung (BDO) RT., and Yogyakarta (JOG) - Surabaya (SUB) RT.. The opening of Adisutjipto International Airport to propeller aircraft makes it possible to increase flight frequencies or new routes. For that, it is necessary to estimate the volume of aircraft passengers at Adisutjipto International Airport using the gravity model. The most accurate model is Model 5, where the attraction force is separated into the number of residents of the origin and destination zones and the GRDP of the origin and destination zones, as well as the distance impedance factor and ticket rates are also separated.

Abstract

The Bili-Bili Dam located in Gowa Regency, South Sulawesi Province, is a rockfill dam with a central core, featuring a total storage capacity of 375 million m³ and sediment storage capacity of 29 million m³. Due to its high risk of structural failure, Bili-Bili Dam is classified as Class IV (Extreme). Recent developments have shown a decline in dam body stability due to seepage issues. If left unaddressed, this could trigger piping or even structural failure, posing a threat to the sustainability of the reservoir's functions. The objective of this study is to evaluate the safety factor (SF) of the main dam, right wing dam, and left wing dam as an integrated structural system of Bili-Bili Dam. The approach combines both qualitative and quantitative methods, including engineering geological assessments and Geostudio SEEP/W to analyze seepage rates and SLOPE/W to evaluate landslide potential. The analysis results indicate that seepage discharge remains within acceptable limits, and the dam’s stability under Operating Basis Earthquake (OBE) conditions is considered safe. However, under Maximum Design Earthquake (MDE) conditions, the slope safety factor does not meet the minimum standard required by SNI 8064:2016. Therefore, remedial actions such as reinforcement or retrofitting of the dam body are necessary.

Abstract

Sabu Island, Sabu-Raijua Regency, is dry area, recorded having Lere Dam, which is no functioning, caused by a sinkhole in the inundation area, and the water disappears immediately becomes dry. The dam rehabilitation requires a desk-study for the potential agriculture and raw water produced. The study methodology includes: monitoring the existing dam; monitoring results analysis consisting of hydrological, geographical analysis and river basin simulation; recommendations for the axis location of the dam with its optimal and effective storage capacity. The results of the geographical analysis and simulation, show that the location of the main dam axis needs to be shifted upstream at the axis position from 10029'41.86"LS and 121056'37.39"BT to 10029'47.29"LS and 121056'41.87"BT. The rainwater catchment area obtained from this analysis is 415,5 ha. With a simulation of a 9,0 m embankment height, it will provide a reservoir storage volume of 1,100 MCM. As a conclusion, it can be written that this dam analysis desk-study is faster and more cost-effective in finding the optimal reservoir capacity and effective dam height. This study needs to be continued by conducting a field survey and detailed analysis.

Abstract

This study evaluates the performance of Global Precipitation Measurement (GPM) satellite-based rainfall data in comparison to Automatic Rainfall Recorder (ARR) data in forming rainfall distribution patterns and assessing its impact on flood discharge simulation using the HEC-HMS model. Statistical validation was conducted using the Pearson Correlation Coefficient, the ratio of standard deviation of observations to RMSE (RSR), Percent Bias (PBIAS), and Mean Absolute Percentage Error (MAPE). The results show that GPM has a strong correlation with ARR (r = 0.875) and a low RSR value (RSR= 0.256), yet it exhibits a notable negative bias (PBIAS = –24.41%), indicating an underestimation of rainfall values. In contrast, simulations using ARR rainfall patterns produce peak discharges that closely match actual discharge records at the Jatigede Dam outlet, with an average deviation of less than 3% and a MAPE of 1.17%, categorized as very good. The GPM simulation produces peak discharges 13–16% higher than actual observations, with a MAPE of 14.53%, which still falls into the good category. These results suggest that while ARR provides higher accuracy, GPM remains a viable alternative source, especially in data-scarce areas, provided that appropriate calibration methods such as bias correction are applied. This study supports future research in satellite data calibration using machine learning and multivariate statistical approaches.

Abstract

Roads built on soft clay soils will experience damage before the service life is complete. One of the most common damages is potholes. The cyclic load is the repetitive load caused by the wheels of a vehicle. Stabilization of the subgrade needs to be done to overcome this problem, namely by adding lime. The lime used is quicklime from Sampang, Madura. The research was conducted to obtain the optimum lime mixture in the soil. CBR test was conducted on the soil with 3%, 5%, and 7% lime mixture. After that, cyclic loading was applied to analyze its effect on the CBR value. The original soil had a CBR value of 11.36% which then decreased to 5.79% after cyclic loading. The CBR values of 3%, 5%, and 7% lime-stabilized soil were 31.96%, 35.22%, and 34.48%, respectively. The optimum lime mixture in this study is 7% with a CBR value of 34.48% and a decrease in CBR value due to cyclic loading to 30.74%. Stabilization with lime can increase the CBR value up to 5% lime mixture. The addition of excess lime will reduce the CBR value. In addition, the decrease in CBR value due to cyclic loading decreases with the addition of lime. This is because the absorption and flocculation reactions by lime cause changes in the distribution of soil grain gradation.

Abstract

Urban drainage systems play a critical role in managing excess water to prevent flooding, yet challenges such as rapid urbanization, land-use changes, and climate change exacerbate these issues. In Semarang, factors like clogged channels, sedimentation, land subsidence, and tidal flooding further complicate drainage management. The Organisation for Economic Co‑Operation and Development (OECD) Water Governance approach, with its emphasis on effectiveness, efficiency, and stakeholder engagement, provides a promising framework for improving water governance. However, its application in Indonesia, particularly in Semarang, remains underexplored. This study evaluates the implementation of OECD Water Governance principles in managing the Tenggang River drainage system to promote sustainable water governance. Using the OECD Water Governance Indicator Framework, the research assesses the application of 12 principles through a combination of literature review, questionnaires, and interviews with government officials and community representatives. A descriptive analysis supported by interview findings reveals that the principles are moderately well implemented, though discrepancies exist between government and community evaluations. Government respondents provided higher scores for the dimensions of effectiveness (4.70), efficiency (4.73), and trust & engagement (4.88), compared to the community’s scores of 4.30, 4.07, and 4.40, respectively. Nonetheless, both groups rated the trust & engagement dimension the highest among all.
