Abstract

The toll road of Padang - Sicincin uses earth embankments in the construction process. In earth filling work, there is a target that must be met, namely that it must be able to spread and compact the soil by 1,474,809 m3/day, where this volume is the plan to meet the target that has been set. The problem that is currently occurring is that the land for the toll road entrance at STA 13+300 – 13+900 on Jalan Nagari Lubuk Alung has just been acquired in 2022. From the results of a field inspection that took approximately a week, there was a delay in terms of landfill work. in the field. Therefore, it is necessary to research to find out the causes of delays. The focus of this research is to determine the productivity of heavy equipment to determine solutions to catch up with work delays that are occurring. After conducting a review in the field, the results obtained from each heavy equipment were 1,471,150 m3/day (excavator), 1,464,610 m3/day (dump truck), 3,086,070 (bulldozer), and 4,150,272 m3/day. (vibro roller). From the results obtained, the excavators and dump trucks in the field were unable to meet the planned targets. Therefore, the handling efforts carried out are by increasing the number of excavators and dump trucks working in the field. Based on the results of calculations and analysis, to complete the embankment work on time, increase the number of tools by two units for excavators and three units for dump trucks. With this additional simulation, the time required to complete work in the field is 13 days faster than the planned time that had been made.

Abstract

Seepage is an inevitable occurrence in embankment dams, but under certain conditions, it can lead to piping. Piping is the formation of cavities in the soil due to the transport of fine soil particles by seepage forces. This phenomenon is one of the serious issues that can affect the stability of the dam. This study aims to analyze the potential for piping in one of the dams located in West Java using finite element and empirical equation methods. The finite element method analysis was conducted to obtain the exit hydraulic gradient values in the dam to calculate the safety factor against piping hazards. Meanwhile, the empirical equation used the weight creep ratio (WCR) to assess the potential for piping. The potential for piping analysis was conducted under minimum, normal, and flood water level conditions. The results of the finite element analysis showed that the hydraulic gradient exit values ranged from 0.20 to 0.33, resulting in safety factors ranging from 4.58 to 8.25. The obtained safety factors still meet the minimum safety factor criteria required by SNI 8065:2016, which is 4. The potential for piping analysis using the empirical approach yielded WCR values under the minimum, normal, and flood water level conditions, which were 4.71, 3.36, and 3.30, respectively. The calculated WCR values are higher than the typical value for WCR in hard rock, which is 1.6. Based on these two analyses, it can be concluded that the dam is safe against piping hazards.

Abstract

Daerah Aliran Sungai (DAS) merupakan sebuah kawasan yang luas dan punggung gunung sebagai batasannya dimana air hujan yang turun di daerah tersebut akan ditampung/disimpan oleh pegunungan tersebut kemudian dialirkan memalui sub-sub sungai ke sungai utamanya dan akhirnya bermuara ke waduk,danau atapun ke laut. DAS juga merupakan daerah yang memiliki sumber kehidupan pokok manusia, kebetuhuna pokok tersebut dapat dipenuhi oleh sekitaran daerah tersebut, seperti kebutuhan air untuk memasak, kebuthuan air untuk mandi, dan juga daerah tersebut dapat memenuhi kebutuhan pertanian dikarenakan daerah tersebut memiliki tanah yang subur dan air yang mampu untuk memenuhi kebutuhan tumbuhan, sehingga daerah ini bisa dimanfaatkan oleh masyarakat sebagai pemukiman. Adapun permasalahan yang terjadi dan ingin diselesaikan pada penelitian ini adalah memprediksi/melakukan perkiraan debit banjir yang akan terjadi ketika terjadi musim pernghujan dengan curah hujan yang tinggi pada periode ulang 25, 50 dan 100 tahun dengan metode Hidrograf Satuan Sintetis Nakayasu. Melakukan skenario dalam bentuk penanganan banjir di sepanjang sungai Krueng Aceh. Debit banjir rencana yang terjadi pada das Krueng Aceh dari berbagai periode ulang. Debit yang terjadi pada salah satu hulu Das seperti krueng Inong pada periode ulang 25 tahun debit banjir rencana yanng terjadi adalah Q25 = 1.446 m3/dtk. Dan kala periode ulang 50 tahun Q50 = 1.514 m3/dtk dan untuk periode ulang 100 tahun sebesar Q100 = 1.575 m3/dtk. Dengan debit sebesar ini Krueng Aceh mengalami peluapan sehingga perlu dilakukan langkah mereduksi banjir. Setelah dilakukannya penelusuran sungai ini kita dapat melihat bahwasanya tinggi muka air pada hilir krung aceh sudah menurun pada saat terjadinya debit puncak hal ini dikarenakan debit banjir puncak 1.575 m3/dtk direduksi menjadi 353 m3/dtk. Kondisi muka air sungai pada sungai Krueng Aceh STA + 11.300 setelah direduksi debit banjir rancangannya berada dibawah tinggi dari bantaran sungai dimana tinggi muka air dari dasar sungai sekitar 4,93 m, ini menunjukkan bahwa debit berada dibawah tampungan aman dari sungai Krueng aceh ini atau tidak terjadi luapan air sungai pada sekitar sungai Krueng Aceh.

Abstract

This study evaluates the strength of runway 17/35 at Komodo International Airport using the FAA method and COMFAA V3.0 software. The goal is to determine the Pavement Classification Number (PCN) to optimize the operational capacity of the runway. Runway 17/35 has a length of 2,650 meters and a width of 45 meters, with asphalt pavement. The 2017 Heavy Weight Deflectometer (HWD) test showed a PCN value of 55 F/C/X/T. Aircraft movement data from 2016 to 2020 identified ten main types of aircraft frequently operating, with the B737-800 having the highest Aircraft Classification Number (ACN) of 50 and a Maximum Takeoff Weight (MTOW) of 73,016 kg. The PCN was calculated for three runway segments based on material and layer thickness, showing evaluation thicknesses for segments A, B, and C of 873 mm, 981 mm, and 1123 mm, respectively. The overall calculated PCN value is 52 F/C/X/T. Comparison between the existing PCN value (55 F/C/X/T) and the calculated value (52 F/C/X/T) shows a minor difference. The ACN values of all aircraft operating at this airport do not exceed the runway's PCN value, indicating that runway 17/35 is sufficiently strong to accommodate all these aircraft, including the B737-800. This evaluation ensures the safety and efficiency of flight operations at Komodo International Airport and supports the enhancement of long-haul flight service capacity in the future

Abstract

The characteristics of soil, which are homogeneous or even very different even at short distances, are one of the reasons why it is important to carry out geotechnical investigations for building foundation design to prevent failure or excessive settlement. This research aims to determine the geotechnical characteristics of the container port location plan in Raha City. Deep boring and SPT tests were carried out at 2 points: BH-01 in the wharf area and BH-02 at the access road area to the dock (trestle and causeway). Apart from that, samples were taken from two drilling holes to be tested in the laboratory. Laboratory test results obtained based on the USC classification of all samples were classified as silty sand soil (SM) with low plasticity. The boring results show that the hard soil layers in BH-01 and BH-02 are, respectively, at a depth of 12.5 m and 16.5 m. The allowable bearing capacity (Qa) of round piles with a diameter of 45 cm at a depth of 9 m, 10 m, and 11 m with a safety factor of 4 is respectively 892 kN, 919 kN, and 946 kN for BH-01 and 913 kN, 940 kN, and 968 kN for BH-02. The allowable bearing capacity (Qa) of round piles with a diameter of 50 cm at a depth of 9 m, 10 m, and 11 m with a safety factor of 4 is respectively 1057 kN, 1084 kN, and 1112 kN for BH-01 and 1079 kN, 1106 kN, and 1133 kN for BH-02.

Abstract

Abstrak. Pedestrian facilities are one aspect that has the potential to influence pedestrian safety. The high volume of pedestrian and vehicle traffic on Yos Sudarso Street, particularly in the area of Manpower RDMP JO, has led to the provision of a pedestrian overpass facilities for the Manpower RDMP JO. There are two pedestrian overpass facilities provided for the Manpower of RDMP JO, namely JPO 1 and JPO 2. This research aims to determine whether the pedestrian overpass complies with the standard guidelines of the Directorate General of Highways No. 027/T/Bt/1995, To determine the effectiveness level of pedestrian overpass based on pedestrian volume, and the relationship between pedestrian overpass facilities and pedestrian safety using the chi-square test method with SPSS. The method in this research uses a quantitative approach, based on the results of questionnaires, observations, and documentation. The research results indicate that the existing conditions of JPO 1 and JPO 2 meet the standards set forth in the guidelines for the planning of pedestrian overpasses, based on the standard guidelines from the Directorate General of Highways No. 027/T/Bt/1995. The effectiveness calculated based on the pedestrian volume obtained for each is JPO 1 at 59.9% (Fairly Effective) and JPO 2 at 69.9%. (Effective). From the chi-square test using SPSS, an asymptotic value of 0.00 was obtained. Which means that there is a relationship between variable X (crossing bridge facility) and variable Y ( Pedestrian Safety ). This can be interpreted that pedestrian overpass facilities have a significant impact on pedestrian safety.

Abstract

Slope stability represents a major challenge in infrastructure development, particularly in regions with complex geotechnical conditions. This study aims to evaluate the effectiveness of slope stabilization methods using a numerical simulation approach based on the Finite Element Method. The study was conducted on a road section in Southeast Sulawesi, characterized by silty sand soils prone to erosion. Soil investigation data were obtained through cone penetration tests (CPT) to determine soil parameters for the analysis. The slope reinforcement alternatives involve a combination of gravity-type retaining walls (DPT) with mini bore piles and the installation of gabions on riverbanks. The gabions are intended as a long-term mitigation measure to reduce erosion risks on the riverbanks. Simulation results indicate that integrating DPT with mini bore piles enhances slope stability, achieving a safety factor of 1.58 during flood conditions, meeting the minimum criterion of 1.5 according to SNI 8460:2017. Although scouring effects reduce the safety factor to 1.53, this value remains within acceptable limits. The greatest displacement occurs at the toe of the slope but is effectively minimized with the designed reinforcement. This study highlights the importance of the finite element approach in understanding soil-structure interactions. The findings provide practical recommendations for slope reinforcement, especially in areas with high geotechnical risks. Regular monitoring of riverbank erosion is advised to maintain slope stability sustainably.
