Abstract

Airport pavement is designed following the US Corporation of Engineers method or better known as the California Bearing Ratio (CBR) method and the FAA (Federal Aviation Administration) method which issues regulations for calculating airport pavement structures, namely AC (Advisory Circular) 150_5320_6D which same as the method CBR. In 2021, the FAA issued a standard for calculating airport pavement structures, namely AC (Advisory Circular) 150_5320_6G which uses the FAARFIELD assistance program. The difference in pavement thickness is at most 7.6 cm, on the flexible pavement type base course. In the FAARFIELD Auxiliary Program, all aircraft loads are taken into account as a contributor to pavement damage indicated by the CDF value that can accommodate aircraft loads, in contrast to the graphical method where aircraft are converted to design aircraft. The thickness of the base course using the graphical method is greater than that of the FAARFIELD Assistance Program, this is because when performing calculations, the initial base course value is the minimum value based on the minimum base course table for the use of top foundation layer material (AC No.150_5320_6G). The thickness of the surface course pavement is the same according to FAA provisions for the critical thickness of the surface course which is 4 in or 102 mm.

Abstract

The Synthetic Unit Hydrograph (SUH) method is a very important method in water resource planning and flood discharge analysis in river basins This method is very useful, especially for flood simulations in river basins that experience changes in land use. However, The HSS method generally has shortcomings, including difficulties in explaining the origin of peak discharge formulas and inaccuracies in comparing hydrograph volumes with effective rainfall. Additionally, there are challenges in adapting the method for different rainfall durations, and only a few methods can be calibrated. To overcome these challenges, the ITB SUH method has been developed with several innovative features. This method follows the mass conservation principle and simplifies the process of deriving peak discharge formulas, making it an effective educational tool. The ITB method combines exact and numerical approaches in calculating the Peak Discharge Factor (Kp), improving the accuracy of peak discharge estimation, which is very important in flood management. This method also introduces the Normalized Unit Rainfall Duration (Tn), a dimensionless factor that provides flexibility in adjusting the hydrograph duration, making it easier to convert to shorter durations. In addition, the ITB method includes a calibration mechanism that allows users to adjust the hydrograph with measurement values. The ITB SUH method's innovative features have been successfully demonstrated in various cases, yielding highly positive outcomes.

Abstract

The use of steel materials in building construction opens new opportunities for sustainable development, as steel exhibits corrosion resistance, durability, and reliability in terms of strength and ductility. Digital Image Correlation (DIC) is non-contact technique in which digital images of the surface of a test object are captured using high-resolution cameras.  This study conducted measurements of strain distribution on the specimen's surface using the DIC method throughout the entire tensile testing process. The study particularly focuses on examining changes in strain distribution during the melting phase and the local deformation phase leading to fracture. In this research, a comparison will be made between the load-displacement curves obtained from experimental laboratory testing and the results analyzed using the DIC method for SS400-grade steel material. Based on the results of the tensile test and DIC analysis that have been conducted, conclusions have been drawn in the research. The tensile test results of SS400 steel material with a thickness of 6 mm, 8 mm, 10 mm, and 12 mm meet the quality requirements in the tested specification standards, and the results of the force-displacement curve between the experimental test results and the DIC method obtained a minimum deviation with a value below 10%,. Therefore, it can be concluded that the DIC method exhibits a reasonably good level of accuracy, making it suitable for validating the results of experimental tests.

Abstract

The existing subgrade for road construction is quite diverse, and sometimes it does not meet the standards for construction subgrade. Repair efforts are needed if the existing land has a fairly low CBR (California Bearing Ratio) value. Stabilization materials for soil improvement can use waste in the form of marble ash, and as a comparison in this research improvements were also conducted using the biogrouting method. The aim of this research is to obtain the effect of marble ash stabilization and biogrouting on the CBR value. The research was carried out through CBR tests on a physical model of soil stabilized with 3-6% marble ash and soil improved using the bacteria bacillus subtilis and bacillus amyloliquefaciens. Tests are differentiated based on the thickness of the stabilized soil, which is 10–30 cm. The research results showed that marble ash-stabilized soil resulted in a better increase in CBR values compared to soil improved using the biogrouting method. CBR values that meet standards for road construction base soils are obtained on soil stabilized with 6% marble ash with a minimum stabilized soil layer thickness of 20 cm.

Abstract

Indonesia is a country affected by the El Nino and La Nina climate anomalies. The provinces of Aceh, Central Kalimantan, and Maluku are three regions representing parts of Indonesia that have a variety of rainfall distribution and climatic conditions. This research was conducted to determine the influence of the El Nino and La Nina climate anomalies on these three regions by looking at the areas that have a dominant influence due to these climate anomalies. The research used BMKG Indonesia rainfall data with a total of 16 rainfall stations and a data range of 22 years. The methods used for modeling are the Fast Fourier Transform (FFT) and Lomb Periodogram to obtain rainfall spectrum data. Then, the amplitude value was obtained, and a comparison of the data from the two methods was carried out to determine the recurrence value and the area with the highest impact due to climate anomalies. The results of data analysis according to the FFT and Lomb Periodogram showed that the highest affected area was the eastern part of Indonesia, namely Maluku Province, with the dominant frequency according to the FFT method being 5.61 years with a PSD of 7.67 mm2 and the Lomb Periodogram 6.06 years with a PSD of 18.64 mm2. Based on the average PSD value, using both FFT and Lomb Periodograms, it also shows that the influence of El Nino and La Nina is greatest in the eastern part of Indonesia; as you move towards the west, this influence decreases. The smallest influence occurred in western Indonesia. This shows that the influence of ENSO is more dominant than the influence of IODM.

Abstract

The Tegal Siwalan-Banyuanyar Highway in Probolinggo Regency has been damaged at several points and has not received any maintenance for the last 7 years. This has a huge impact on road users because it can interfere with driving comfort and safety, so it is necessary to analyze the road damage that has occurred, including the type of damage and an assessment of road conditions. The Bina Marga method and a light-weight deflectometer (LWD) can be used to assess road deflection in order to assess road condition. The results of this study obtained priority order values for each segment that were in the range 5-11. The greater the value of the Order of Priority obtained, the better the road condition, whereas the smaller the value of the Order of Priority obtained, the worse the road condition. It was also found that the Bina Marga method and the Light Weight Deflectometer (LWD) tool had a poor correlation, so a comparison between the two could not be made for assessing the condition of the road surface layer.

Abstract

A level crossing between railways and roads is one of the critical traffic elements in a road network system as it can cause significant delays and long queues, especially when the crossing is part of an urban road network. This study aims to analyze traffic performance at level crossings using a microsimulation approach with the PTV VISSIM software. The model is designed to explicitly simulate the interaction between trains and vehicles by utilizing features such as priority rules, public transport lines, and reduced speed areas, and calibrating it based on field data. This research takes a case study of the level crossing at Jalan Abdul Rahman Saleh – Nurtanio, Bandung City. Data collection was conducted through direct observation via field surveys and data from supporting literature documents. The analysis results indicate that the existing traffic performance is at a Level of Service F, with an average intersection delay exceeding 60 seconds per vehicle. Microsimulation recommends the construction of a grade-separated intersection as a solution to improve traffic performance in the future.

Abstract

Simpangan antar tingkat terjadi akibat adanya deformasi rotasi pada titik kumpul sebagai respon dari gerakan tanah akibat gempa. Deformasi rotasi terjadi sebagai akumulasi dari deformasi lentur pada balok dan kolom serta deformasi geser panel zone. Studi ini dibuat untuk mengetahui bagaimana deformasi tidak linear siklik yang terjadi pada elemen balok dan zona panel pada struktur rangka baja akibat gempa. Model adalah SRPMK baja 8 tingkat yang dibangun di atas tanah kelas D dan didesain untuk kategori desain seismik D. Analisa dinamik tidak linear, memakai 20 rekaman gempa dilakukan untuk mendapatkan nilai median simpangan antar tingkat untuk ditentukan kurva kerapuhannya. Hal ini dilakukan untuk mengidentifikasi kapasitas pada kondisi batas LS, CP dan runtuh yang dimiliki oleh model, yaitu deformasi lentur dan geser tidak linear yang terjadi pada elemen balok dan panel zone pada lantai 1 eksterior. Hasil yang diperoleh menunjukkan bahwa deformasi rotasi pada balok akibat lenturan pada akhir getaran gerakan tanah adalah lebih besar bila dibandingkan dengan deformasi rotasi saat simpangan antar tingkat mencapai kondisi LS dan CP pada saat pertama kali. Hal yang sama juga terjadi pada deformasi geser di zona panel yang ditinjau.
