This study examines the application of double integrals in calculating the volume of cylindrical concrete piles as a basis for estimating material requirements in building foundation structures. The volume calculation was carried out using a double-integral approach in polar coordinates for three pile segments with lengths of 4 m, 3.9 m, and 4 m, each having a diameter of 60 cm. The results were then validated using the standard geometric formula to ensure consistency and mathematical reliability. The obtained concrete volume was subsequently used to estimate material needs based on a 1:1.5:3 mix proportion consisting of cement, sand, and gravel. The findings indicate that double integrals can be effectively applied to generate accurate estimations of both volume and material requirements, supporting logistical planning in construction. This approach also highlights the strong connection between mathematical concepts—particularly multivariable calculus—and practical applications in civil engineering. Furthermore, the study emphasizes that double integrals may serve as a relevant alternative when structural modeling requires deeper analytical exploration or validation beyond conventional geometry. Therefore, the implementation of double integrals not only reinforces theoretical understanding but also enhances precision in evaluating structural components within building foundation planning.

Bangunan yang berada di daerah rawan gempa dengan tanah lunak cenderung memiliki tingkat kerentanan yang lebih tinggi. Dalam merancang struktur bangunan bertingkat, beban gempa menjadi salah satu parameter utama yang sangat berpengaruh. Kekuatan sebuah bangunan ditentukan oleh elemen-elemen struktur yang menopangnya dan kolom merupakan elemen struktur yang memiliki peran penting dalam konstruksi. Jika kolom mengalami kegagalan, bangunan yang ditopangnya berpotensi runtuh. Oleh karena itu, rendahnya ketahanan konstruksi di wilayah ini tetap menjadi permasalahan yang sedang diteliti saat ini. Tujuan penelitian ini untuk mengetahui seberapa jauh pengaruh variasi dimensi kolom terhadap struktur bangunan terhadap gempa, sehingga diperoleh ukuran dimensi kolom yang paling optimal. Pada penelitian ini, objek yang digunakan adalah bangunan 8 lantai yang terdiri dari lantai 1-3 merupakan kantor dan lantai 4-8 merupakan hunian. Pada perencanaan ulang bangunan ini berpedoman pada persyaratan beton struktural (SNI 2847:2019), perencanaan ketahanan gempa (SNI 1726:2019), dan beban minimum untuk perancangan bangunan gedung dan struktur lain (SNI 1727:2020), dengan pemodelan menggunakan software ETABS V.22. Redesain bangunan ini untuk mengetahui ukuran dimensi kolom yang paling optimal. Hasil penelitian perubahan dimensi kolom terhadap kekuatan struktur bangunan yakni dengan memperbesar dimensi kolom, kapasitas penampang bertambah yang dapat meningkatkan ketahanan kolom terhadap beban gempa. Selain itu, dimensi yang lebih besar juga membantu mengurangi tegangan aksial pada kolom, sehingga menurunkan risiko kegagalan akibat tegangan berlebih atau kelelahan material. Semakin besar dimensi kolom yang digunakan maka semakin kecil nilai simpangan yang dihasilkan. Artinya dengan dimensi kolom yang lebih kecil memiliki resiko yang lebih tinggi, sebab nilai simpangan lebih dekat dengan batas yang diijinkan. Akan tetapi hasil analisis menunjukkan bahwa dimensi kolom dengan berbagai variasi masih aman dari pengaruh delta izin.

Delays in high-rise building construction projects in Surabaya are a crucial issue as they can significantly affect cost, quality, and project completion schedules. This reserach intends to identify the dominant factors contributing to project delays using the Relative Importance Index (RII) method, considering both frequency and impact aspects. Data were obtained from 80 valid respondents who hold strategic roles in construction project implementation, such as Project Managers, Site Managers, Site Engineers, Estimators, Field Supervisors, General Managers, and Company Directors. The analysis results indicate that in terms of frequency, the dominant factors are unfavorable weather conditions (RII = 0.750), labor shortages (RII = 0.743), and design changes during construction (RII = 0.735). Meanwhile, in terms of impact, the dominant factors are delays in material delivery (RII = 0.780), labor shortages (RII = 0.770), and substandard material quality (RII = 0.740). These findings emphasize that labor shortage consistently influences project delays in both frequency and impact, while weather and material factors show different patterns between occurrence and consequence. All dominant factors were classified into the High-Medium category, indicating that they should be prioritized in project risk management.

The study provides participants with opportunities to understand Qur’anic verses contextually and relate them to daily life, while also building an inclusive and egalitarian learning community. The contributions of Kajian Kalam include broadening access to Qur’anic interpretation for participants with diverse backgrounds, implementing participatory learning models, and developing grounded and practical Qur’anic literacy. This research demonstrates that community-based Qur’anic studies can be an effective means to improve understanding and practice of the Qur’an, filling a gap in previous studies that focused primarily on formal institutions. The findings are expected to inform the development of more participatory and practical Qur’anic study models in society.

The rapid advancement of science and technology requires universities to provide safe, comfortable, and representative learning facilities. One such initiative is the construction of a five-story lecture building at Dr. Soetomo University, designed with a steel structure as an alternative to reinforced concrete. Steel was chosen due to its high tensile strength, uniform material properties, lighter weight, ease of installation, and strong resistance to earthquake loads. This study aims to design a five-story lecture building with a steel structure that meets the requirements of strength, stability, and safety in accordance with applicable standards. The method applied is structural planning based on SNI 1729:2020, SNI 1727:2020, and SNI 1726:2019 using the Load and Resistance Factor Design (LRFD) approach. Structural analysis was conducted with SAP2000 version 2014 through three-dimensional modeling that considers geometry, material properties, loading, and placement. The results show that the selected steel profiles for beams, columns, and connections are capable of supporting the combination of dead loads, live loads, and seismic loads with safe performance. The maximum stress remains below the allowable limit, and the deflection values do not exceed the permitted deviation. These findings confirm that steel provides efficiency in dimensions and materials while offering practicality and earthquake resistance, and the design produced can serve as a useful reference for future multi-story building projects in earthquake-prone regions.
