Abstract

Konstruksi perkerasan jalan Asphalt Concrete–Binder Course (AC-BC) berperan penting dalam infrastruktur transportasi, namun masih mengalami kerusakan dini akibat beban lalu lintas, kondisi iklim, dan penetrasi air yang melemahkan ikatan aspal–agregat. Penelitian ini bertujuan menganalisis durabilitas campuran AC-BC dengan penambahan limbah uPVC sebagai aditif terhadap variasi waktu perendaman air. Kadar uPVC yang digunakan sebesar 6% dengan KAO 5,15% berdasarkan penelitian (Anjani, 2025) yang menunjukkan kinerja optimum campuran. Metode penelitian dilakukan secara eksperimen laboratorium menggunakan 15 benda uji yang dibagi dalam lima variasi waktu perendaman, yaitu 1, 2, 4, 24, dan 48 jam, masing-masing tiga benda uji. Pengujian Marshall digunakan untuk memperoleh nilai stabilitas, flow, Marshall Quotient (MQ), serta karakteristik volumetrik (VIM, VMA, VFB). Hasil menunjukkan peningkatan waktu perendaman menurunkan stabilitas dari 1473 kg menjadi 1041 kg, MQ dari 342,6 kg/mm menjadi 226,3 kg/mm, serta durabilitas dari 96,74% menjadi 68,36%. Sebaliknya, nilai flow meningkat dari 4,30 mm menjadi 4,60 mm akibat melemahnya ikatan aspal–agregat. Parameter volumetrik relatif stabil dan masih memenuhi spesifikasi. Dapat disimpulkan bahwa uPVC 6% memberikan ketahanan awal yang baik terhadap air, namun menurun seiring waktu perendaman sehingga durabilitas jangka panjang tidak memenuhi batas minimum. Penelitian ini menunjukkan potensi uPVC sebagai aditif ramah lingkungan.

Abstract

The construction of the Mataram Mayor's Office requires pile foundations with adequate bearing capacity to support the building load and improve the quality of public services. This study analyzes the bearing capacity of pile foundations based on SPT test data using several calculation methods, and compares them with the results of the PDA dynamic test. By comparing several bearing capacity calculation methods, this study aims to identify the level of accuracy and deviation of theoretical estimation results from actual conditions in the field. The research method used is quantitative analysis by utilizing Standard Penetration Test (SPT) test data as the basis for calculating the bearing capacity of pile foundations using several empirical methods, namely the O'Neil & Reese, Luciano Decourt, and Briaud et al. The results show that the bearing capacity values of pile foundations calculated based on SPT test data using various empirical methods differ from the results of the PDA dynamic test, but are still within a technically acceptable range. These differences are influenced by soil characteristics and the assumptions of each method, so that certain methods tend to show results that are closer to actual conditions in the field. Pile foundation planning relies not only on theoretical calculations based on SPT data but also combines them with PDA dynamic test results to improve the accuracy and reliability of the foundation design. Furthermore, the choice of bearing capacity calculation method must be adapted to local soil conditions to ensure more representative and safe planning results.

Abstract

The Mataram Mayor's Building, West Nusa Tenggara, consists of 3 floors with a total height of 14.25 m. All floors of the building use reinforced concrete structures, which make them vulnerable to lateral forces, especially those caused by earthquakes. Earthquakes risk causing building damage, therefore a special frame-bearing structure is needed to withstand earthquake forces to prevent structural failure, therefore shear walls are needed to withstand lateral forces. The placement and shape of shear walls affect the building's ability to withstand lateral forces. The problem of researchers in this study is how to compare the effectiveness of the four variations of shear walls when resisting lateral forces. So that researchers get the goal of knowing the value of floor deviations in the x and y directions and knowing the optimal placement location point in resisting lateral forces. In this study, a general type of data collection method is used, namely data collection carried out by collecting working drawings from project service providers. Based on the results of the analysis of the four existing models, it can be concluded that the placement of the shear wall position is more effective if placed at the right corner of the L-shaped building, if viewed from the results of the floor deviation values in the x and y directions. Where the overall floor deviation in the x direction of variation 1 is 1.12 mm, while the deviation in the y direction is 2.80 mm.

Abstract

Ring of Fire and at the intersection of three tectonic plates. Efforts are needed to minimize earthquake damage, one of which is the use of a base isolator system. This study aims to determine the effect of using High Damping Rubber Bearing (HDRB) with a diameter of 800 mm on the behavior of reinforced concrete structures in tall buildings under seismic loads. The research location is the 7-story Sapadia Hotel building in the city of Mataram. The research is conducted by analyzing a 3D model of the fixed base structure and the base isolator structure using numerical analysis. The results show an increase in the base displacement of the base isolator structure by 59% in the x-direction and 44% in the y-direction, while the inter-story displacement decreases by 36% in the x-direction and 69% in the y-direction. The use of base isolators can reduce the shear force by 35% in the x-direction and 15% in the y-direction. Based on the pushover analysis, the roof displacement values for the fixed base and base isolator structures are 0.159 m and 0.129 m respectively. These values can be used to determine the structural performance level according to ATC-40. The maximum drift value for the fixed base structure is 0.0055 m. For the base isolator structure, the maximum drift value is 0.0044 m, categorized as Immediate Occupancy (IO). This value can be used to determine the performance level of the structure based on ATC-40. The maximum drift value of the fixed base structure is 0.0055m. While in the base isolator structure, the maximum drift value is 0.0044 m which is included in Immediate Occupancy (IO). Thus, the use of base isolators in high-level buildings is able to reduce post-earthquake damage and the building is still safe to continue using.

Abstract

Lombok Island is one of the earthquake-prone areas, located between two earthquake generators. Based on these conditions, it is expected that construction in earthquake-prone areas can meet the standards. Shear walls are one of the earthquake-resistant structural systems used to resist lateral forces. Three alternative shear wall shapes will be analyzed using the numerical method: the L, I, and T shapes. The types of loads to be analyzed are dead loads, live loads, and earthquakes. Drawing from the findings of the conducted analysis, it is discovered that the most effective shear wall position in resisting lateral forces is the shear wall located at the corner of the building, based on the values of the drift that occur in the x and y directions. In addition, increasing the number of shear walls can reduce the internal forces that structural components experience. The optimum drift value is obtained from alternative 1, the L-shaped shear wall (elbow), with a drift value of 0.000495 mm in the x direction and 0.000883 in the y direction.
