Abstract

The road in front of the firefighting study program at the Palembang Aviation Polytechnic experienced serious damage in the form of transverse cracks and a 4.6 × 4.6 m collapse. This damage was caused by the frequent passage of heavy foam-tender vehicles during practice, disrupting operations and endangering user safety. This condition indicates the need for pavement capable of withstanding high dynamic loads in a limited area. This study aims to redesign the rigid pavement layer in the courtyard of the PPKP Poltekbang Palembang Building. Specific objectives include identifying the type and severity of damage, calculating traffic and vehicle loads (ESAL), and determining the optimal pavement thickness for structural repair. The research applied a quantitative approach with primary data from field observations and damage measurements, and secondary data from literature and PKP-PK vehicle specifications. Analysis was conducted using the AASHTO 1993 method with a focus on ESAL calculations to determine rigid pavement thickness. Results showed that damage was due to heavy foam tender traffic. The 20-year cumulative ESAL of 84.25 is considered low, but the high axle load requires a minimum 20 cm concrete slab for safety and optimal service life. This research provides technical recommendations for safe, efficient road repairs in campus areas with high dynamic loads.

Abstract

Liquefaction is one of the dangerous geotechnical phenomena that often occurs due to earthquakes, especially in saturated sandy soils that are not cohesive. Although the area of Langsa City, Aceh is classified as having relatively low seismic activity, the condition of the water-saturated soil still makes it vulnerable to this phenomenon. This study aims to analyze the potential for liquefaction at the Langsa Depot Project site using the Standard Penetration Test (SPT) method. The method used involves correcting the value of N-SPT to N1(60), then the calculation of the Cyclic Stress Ratio (CSR), Cyclic Resistance Ratio (CRR), and Safety Factor (FS) based on the. SPT data was obtained from one drill point with a depth of 50.5 meters and combined with regional seismic data (magnitude 5.1 SR and earthquake acceleration of 0.2 g). The results of the study showed three layers of silty sand that were the focus of the analysis, namely at depths of 6–8 m, 28–35 m, and 48–49 m. The first layer has an FS value of > 1 (1.083 – 1.168) which indicates that this layer does not have the potential for liquefaction, for the second layer has an FS value of > 1 (1.817 – 1.899), so it is declared not to have the potential for liquefaction and is categorized as safe, and the third layer has an FS value of > 1 which is (2.012) is also declared safe from potential liquefaction. These findings confirm the importance of liquefaction evaluation for safe geotechnical design. The study concluded that the project site has two zones that are vulnerable to liquefaction and require mitigation. Keywords: liquefaction, SPT, safety factor, sandy soil

Abstract

Providing an emphasis on the second-floor slab and beams, this study provides a thorough investigation of the bending and cracking seen in the concrete structures of Classroom 1A at SDIT Auliya Balikpapan. In multi-story buildings, excessive deflection and critical fracture widths can seriously jeopardize serviceability, user comfort, and structural integrity [1], [2]. The present state of the structure was evaluated in detail utilizing a combination of Finite Element Method (FEM) analysis using LISA FEA and Non-Destructive Testing (NDT) techniques, such as Ultrasonic Pulse Velocity (UPV), Crack Width Test, Rebar Scanner Test, and Schmidt Hammer Test. The results showed that although the majority of the beams had acceptable crack widths and deflection, the second-floor slab had a considerable 30 mm deflection, which was more than the 19.44 mm allowed by SNI 2847:2019 [3], [4] , and some of the beams (R1.B1, R1.B2, and R2.B4) also had crack widths that were greater than the 0.41 mm threshold [5], [6]. Additionally, FEM analysis revealed stress concentrations in the slab that exceeded the nominal compressive strength of the concrete. In order to restore the classroom building's structural safety and long-term durability, a retrofitting solution utilizing Fiber Reinforced Polymer (FRP) is suggested, along with ongoing monitoring and possible reevaluation of design criteria.

Abstract

Polyethylene Terephthalate (PET) is a type of plastic waste that degrades very slowly and has the potential to cause environmental pollution. The use of PET as an artificial aggregate in concrete mixtures is an alternative to reduce dependence on natural aggregates while minimizing negative impacts on the environment. This study aims to evaluate the effect of coarse aggregate substitution using PET on the compressive strength of concrete at 7 days of age. Cylindrical test specimens measuring 15 × 30 cm were made with PET substitution variations of 0%, 5%, 10%, 15%, 20%, and 25%. Compressive strength testing was carried out at 7 days with a target compressive strength of 20 MPa. The test results showed a decrease in compressive strength as the PET substitution content increased. Normal concrete had an average compressive strength of 24.89 MPa, while 5% substitution resulted in 20.38 MPa and 10% substitution resulted in 17.39 MPa, which still met the planned compressive strength range. At 15% substitution, the compressive strength decreased to 16.10 MPa, at 20% to 14.80 MPa, and at 25% to 11.80 MPa. Based on these results, the use of PET as a partial replacement for coarse aggregate is considered effective up to a substitution limit of 5%–10%.

Abstract

This study is titled "Performance and Quality Analysis of Public Transportation Services in Ambon City (Laha-Ambon Route)", aiming to evaluate the performance and service quality of public transportation on the Laha-Ambon route and analyze the relationship between technical performance and service quality based on user perceptions. The research employs a quantitative descriptive approach with primary data collected through dynamic surveys, static surveys, and interviews with 100 users. Service performance is measured using seven main indicators according to the Directorate General of Land Transportation standards: load factor, frequency, fleet availability, travel speed, headway, service time, and travel time. Service quality is analyzed using the Importance Performance Analysis (IPA) method based on 20 attributes covering comfort, accessibility, reliability, and safety. The results indicate that the performance of the public transportation service on the Laha route falls into the "moderate" category with a total score of 12, while the quality of service from users’ perceptions is considered "good" with a suitability level of 67.01%. Correlation analysis shows a strong positive relationship between technical performance and service quality (r=0.653; p < 0.05). Although some technical indicators are not yet optimal, user satisfaction remains high due to directly experienced service factors such as ease of boarding and alighting, security, and polite driver behavior. The study recommends improvements on the less optimal performance indicators, adjustments of operational standards to be more adaptive to user needs, and continuous communication enhancement with users to improve service quality.

Abstract

Perkebunan Lestari Road is a local road that functions as public access to plantation and residential areas in Sungai Awan Kiri Village, Muara Pawan District, Ketapang Regency, West Kalimantan, Indonesia. The existing road condition is an unpaved dirt surface that suffers severe damage, particularly during the rainy season, resulting in reduced accessibility and vehicle comfort. This condition highlights the need for proper pavement planning to support transportation activities and local economic development. This study aims to determine the Average Daily Traffic (LHRN), evaluate the subgrade bearing capacity based on the California Bearing Ratio (CBR), design the rigid pavement thickness, prepare planning drawings, and estimate the construction budget for the development of Perkebunan Lestari Road. The research employed a quantitative approach with data collection through field observation, literature review, and documentation. The rigid pavement thickness design refers to the Indonesian National Standard SNI 8457:2017 Pavement Design Catalog, considering road classification and traffic loading. Field investigation results indicate a planned rigid pavement length of 500 m and a width of 3 m. The analysis shows that the LHRN value is 0.67 vehicles, indicating low traffic volume, while the average CBR value of the subgrade soil is 6.64%, representing moderate soil strength. Based on these parameters, the pavement structure consists of a 0.05 m thick lean concrete layer and a 0.15 m thick concrete slab. The estimated total construction cost for the rigid pavement is IDR 619,012,526.00. The proposed pavement design is expected to improve road performance, enhance traffic flow, and support plantation and community activities along the road.
