Abstract

Ketebalan konstruksi perkerasan merupakan elemen krusial dalam menjamin masa layanan jalan yang andal di bawah pengaruh beban lalu lintas berulang dan kondisi lingkungan yang dinamis. Penelitian ini bertujuan untuk mengevaluasi keandalan ketebalan perkerasan berdasarkan analisis kelelahan (fatigue) dan deformasi permanen dengan mengacu pada metode AASHTO 1993 dan Manual Desain Perkerasan (MDP) 2024. Lokasi kajian berada pada ruas jalan BTS Kampar – BTS Kota Bangkinang yang mengalami peningkatan volume kendaraan secara signifikan. Analisis dilakukan melalui pemodelan numerik menggunakan perangkat lunak KENPAVE dengan mempertimbangkan variasi faktor kerusakan kendaraan (Vehicle Damage Factor/VDF) dan tingkat pertumbuhan lalu lintas sebesar 4,83% hingga 10%. Hasil menunjukkan bahwa ketebalan konstruksi yang dirancang dengan memperhatikan kondisi lalu lintas aktual menghasilkan masa layanan yang lebih optimal. Kombinasi asumsi VDF faktual 10 tahun memberikan masa layan lebih panjang dibandingkan skenario dengan kombinasi VDF faktual 2 tahun dan normal 8 tahun. Temuan ini diharapkan dapat menjadi acuan dalam perencanaan struktur perkerasan yang lebih andal dan berkelanjutan.

Abstract

Liquefaction is a process of changing soil properties when the solid state becomes liquid caused by cyclic loads as a result of an earthquake so that the pore water pressure increases, approaching and even exceeding the magnitude of the total pressure. Liquefaction occurs due to earthquakes that occur in the area. Tectonic earthquake is one type of earthquake that can trigger liquefaction. The purpose of this study was to examine the potential for liquefaction in Kulon Progo Yogyakarta as the location of the New Yogyakarta International Airport, analyze the safety score (FS), and the value of the liquefaction potential index (LPI). The method used is the Idriss – Boulanger (2014) method using SPT data which is tested at three test points, namely BH-01, BH-03, and BH-06. For this study earthquake data were obtained from the USGS site and the 2017 Earthquake Hazard Map with variations in the earthquake magnitude used were 5.00; 6.30; and 8.10 and ground acceleration data using a probability of 7% in 75 years with a return period of 1000 years. Soil classification based on USCS shows that the soil at the study site is poorly graded sand which contains little fine grain. The results of the study indicate that the research location is prone to liquefaction. Liquefaction occurs at each test point at depth of 4.00 m and 6,00 m, especially at Mw 8.1 and amax 0,48 g with variation where soil resistance is low. Then, based on the classification of the liquefaction potential index numbers which are in the low to high range and the estimated decrease that occurs is up to 23,6 cm.

Abstract

Liquefaction is the transformation of soil into a liquid. The vibrating table in this study moves in a horizontal direction and the opposite manner in a vertical direction utilizing modelling. Acceleration variations of 0.25 g and 0.32 g were employed. The dirt was 10 centimetres thick. The sand clusters were 15 cm thick, with differences in debris gradient size and water surface on the sample. The uniform load that was employed was 40 kg/m2. Examine the drop of the ground surface and the rising of the porous water for signs of liquefaction. A 0.5mm diameter glass pipe was used to measure the porous water pressure. The test findings revealed that with higher acceleration, effective vertical voltage, and porous water ratio values, the rate of particle graduation has a major influence on the occurrence of liquefaction potential. The test results revealed that poorly graduated fine sand experienced maximum effective vertical stress and elevated porous water ratio values (Ru), whereas well-graded sand tended to be more stable.

Abstract

Yogyakarta Special Region (DIY) is an area that has a high level of seismic activity in Indonesia. This is due to various local faults near the land and its location adjacent to the subduction of the Indo-Australian and Eurasian plates. The proposed new airport is located on the coast in Kulon Progo Regency DIY. The location is dominated by the sands layer and it has high ground water levels which indicate the high potential of liquefaction. The site classes of the coast in Kulon Progo Regency is medium category (SD). Liquefaction analysis using the PGAM value of 0.4 g. Liquefaction has the potential to occur in soil layers 0 - 6 meters. The analysis shows for eartquake of ≥ 6.3 Mw has a very high category of liquefaction. The analysis results has LPI ≥ 29.30 for ground water conditions at the surface, and LPI ≥ 15.32 for ground water conditions in depths of 3 meters. Estimated soil settlements of 19.7 cm for magnitude of 8.1 Mw with ground water conditions at the surface. The use of shallow foundations at soil depths of 0-6 meters is not recommended, unless a soil improvement method is used to eliminate the potential for liquefaction.

Abstract

Small coastal peat islands such as Bengkalis (Riau, Indonesia) are hydrologically sensitive systems where groundwater level (GWL) controls ecosystem stability. Both extremes are hazardous: prolonged low GWL elevates peat-fire, subsidence, and carbon-loss risks, while excessively high GWL can trigger bog-burst. This study developed a simple empirical model to predict daily GWL in degraded peatlands on Bengkalis Island using in situ GWL data from three sites (drained, undrained inland, and undrained coastal) and GPM satellite rainfall (October 2023-April 2025). Calibrated over one year and validated over the next seven months, the model performed well at drained and coastal sites (R ~0.82, MAPE ~14%), capturing seasonal dynamics. In contrast, its performance at the inland site was lower (R ~0.5) due to minimal water table fluctuation. Coefficient values indicate the strongest rainfall response and fastest losses at the drained site, negligible daily loss at the inland site, and intermediate behavior at the coastal site. Scenario simulations highlight management-relevant risks: 15 rain-free days cause GWL to drop below the critical -0.40 m fire-risk threshold at the drained site and coastal site, whereas undrained inland remains just above it; conversely, 60 mm/day of rain for four days can raise GWL to the surface at coastal site (bog-burst risk). The model provides a practical tool for informing rewetting strategies to manage fire and collapse risks in degraded tropical peatlands.

Abstract

In geotechnical engineering, professional actions and expert judgment are often essential in soil investigation methods. In lowland and coastal areas, expansive, fine-grained soils and sandy sedimentation lead to reduced bearing capacity, posing significant challenges for sustainable infrastructure development on marginal and degraded lands. Such conditions are prevalent in post-mining or naturally poor coastal environments, necessitating cost-effective and rapid assessment tools. This study modeled a clayey sand mixture using bentonite and kaolin as fine fractions, which exhibit expansive behavior and poor gradation, simulating worst-case geotechnically degraded subgrades. The mechanical behavior of the soil was evaluated through modified compaction, using the CBR test and CPT test as bearing capacity parameters. Soil mixtures were simulated with sand fractions ?65% and bentonite-kaolin compositions with ?50% bentonite. Compaction was modeled using variations in energy compaction and water content under conditions below the maximum dry density. CBR prediction was conducted using Qc as the primary predictor and dry density as a supporting predictor. A hybrid stepwise regression analysis in the         Z-score scale identified positively correlated predictors: +3.00 (Qc), +0.55 (?dry), and +1.28 (Qc ?dry interaction). The regression model showed strong statistical performance with R² = 0.84 and high significance with the lowest p-values. The resulting regression equation offers an applicable approach to rapidly evaluate the bearing capacity of subgrade soils in degraded coastal or marginal conditions, thereby facilitating geotechnical engineering design and initial site assessment crucial for land management and rehabilitation actions.

Abstract

The drinking water supply system (SPAM) is an infrastructure facility specifically designed to provide clean and safe drinking water that meets established health standards. In this project, the construction buildings utilize foundations in the form of piles and bored piles, which serve as essential structural elements to support and distribute loads from the columns to the underlying hard soil layer. A properly designed foundation ensures the stability and durability of the overall structure. This study aims to analyze and determine the bearing capacity of the foundation using several analytical approaches, namely the Meyerhoff, Reese & Wright, and Luciano Decourt methods, while the settlement analysis is carried out using the Fellenius and Vesic methods. The research was conducted in Kampar Regency, Riau Province, Indonesia. The data used in this analysis include Standard Penetration Test (SPT) data and Pile Driving Analyzer (PDA) test results obtained from field observations. The calculation results indicate that the bearing capacity obtained from the Meyerhoff method is 103 tons, Reese & Wright 176 tons, Luciano Decourt 353 tons, and PDA 204 tons. Meanwhile, the settlement results show values of 10.7 mm for the Fellenius method, 16.05 mm for the Vesic method, and 14.5 mm for PDA measurements.
