Abstract

Lalu lintas yang terdapat di dalam industri pertambangan memiliki berbagai macam permasalahan, salah satunya adalah beban kendaraan yang berat dengan muatan yang berat. Studi dilaksanakan di Kutai Timur, Kalimantan Timur dengan lalu lintas angkutan batubara. Studi ini hendak memberikan sisi pandang mengenai solusi dari permasalahan penentuan perkerasan jalan. Perencanaan perkerasan lentur dalam penelitian ini akan menggunakan Bina Marga 2017 dengan mempertimbangkan faktor ESA, lokasi, dan pemeliharaan perkerasan yang akan dilaksanakan. Didapatkan jenis perkerasan lentur berupa Burda atau Burtu dengan lapis pondasi LPA Kelas A. Perkerasan ini dianggap sudah cukup untuk menunjang lalu lintas yang ada.

Abstract

Prayer rooms and mosques have evolved significantly, influenced by their respective regions' cultural and architectural traditions. Mosque construction presents challenges in balancing structural safety, long-term durability, and cost efficiency. This study uniquely combines advanced structural simulation with comprehensive cost analysis to provide an innovative design approach for mosques in earthquake-prone regions. This study utilizes SAP2000 to demonstrate how structural simulations can optimize traditional mosque designs for improved seismic resilience and cost efficiency, using the Musholla Baitul Munjiy in Bawen, Semarang, as a case study. The analysis revealed that some beams and columns had insufficient load-bearing capacity, especially concerning deflection limits. Minor modifications to beam and column dimensions significantly enhanced structural stability, highlighting the potential of targeted design improvements in seismic areas. The refined design met safety standards under seismic simulations and validated the proposed modifications' effectiveness. The findings offer a replicable design framework to enhance both structural resilience and economic viability of small-scale religious buildings in seismic-prone regions.

Abstract

Traffic conditions at a median opening are more complex than signalized or unsignalized intersections. Driving behaviors and the driver's ability to maneuver a U-turn can affect median opening performance. Using software such as PTV Vissim, simulations can be carried out to help analyze traffic conditions and make necessary decisions. This study aims to simulate the median opening u-turn using PTV Vissim to resemble actual traffic conditions and validate it statistically. The calibration involves adjusting traffic volume, headway distribution, speed distribution, driving behaviors, conflict area, and critical gap. One of the important parameters in an unsignalized intersection, especially for U-turn movements at median openings, is the necessary gap. Most simulations still focus on driving behavior parameters, while the critical gap should be used as a calibration parameter to determine safe distances. Additionally, headway distribution predicts the arrival of vehicles that will pass through the median opening. This study adds calibration to the headway distribution parameter and critical gap parameter. The validation MAPE and GEH results for the calibrated simulation are good and acceptable. Meanwhile, the uncalibrated (default) simulation shows poor and unacceptable values. This evidence indicates that calibration is essential in the PTV Vissim simulation. Factors that affect the simulation result are inconsistent drivers, aggressive driver behavior, and inability to comply with priority rules. Driving patterns in mixed and heterogeneous traffic conditions create opportunities and spaces for making U-turns. Simulating this factor is challenging, so a more careful calibration is needed.

Abstract

Daya dukung tiang pancang dapat diperoleh melalui pendekatan statis maupun dinamik. Perhitungan secara statis dilakukan dengan menganalisis sifat-sifat teknis tanah, sedangkan pendekatan dinamik dilakukan dengan menghitung kapasitas ultimit berdasarkan data hasil pemancangan tiang. Penelitian ini bertujuan untuk memperoleh perbandingan dukung tiang dengan menggunakan pendekatan dinamik berbasis data kalendering. Data yang digunakan dalam analisis ini berasal dari proyek konstruksi elevated X di Jakarta, tepatnya pada lokasi titik T38 yang terdiri atas 12 tiang pancang. Perhitungan dilakukan menggunakan empat metode kalendering, yaitu Hiley, ENR, WIKA, dan Navy-McKay. Hasil perhitungan dari keempat metode tersebut dibandingkan untuk melihat variasi nilai kapasitas dan mengevaluasi metode mana yang memberikan hasil paling realistis atau konservatif. Pada perhitungan daya dukung ultimit (Qu) di lokasi proyek X, metode perhitungan kapasitas ultimit tiang pancang memberikan hasil yang bervariasi, dengan metode Hiley menghasilkan nilai tertinggi dan metode ENR paling rendah. Perbedaan ini menekankan pentingnya pemilihan metode yang sesuai dengan kondisi lapangan untuk memperoleh estimasi kapasitas tiang yang akurat dan andal.

Abstract

The capacity of a building to bear the service loads that will be placed on it is a structural requirement. Reinforced concrete is the primary material utilized in this study. Its primary function is to endure the service load and fulfill the requirements stated in the relevant Indonesian standards. SAP2000, employing the finite element method, is utilized in this study to evaluate the building structure's performance in accordance with the relevant service loads. Based on the analysis, the structural element result remains below the allowable standard in terms of deflection; therefore, it does not require an adjustment in the size or quality of the service load performance. The study also reveals that the structural elements of the concrete slab are reacting to the stress and deflection that occur due to the structural service load. Based on the analysis, the highest stress in the deflection of the beam is 0.5816 mm, the highest deflection of the column is 0.089 mm, and the highest tensile stress of the concrete slab is 0.932 MPa. This study's result is an essential concern, where other structural elements, including columns, sloops, and beams, are safe enough to operate according to appropriate standards.
