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.

Prenatal exercise plays a vital role in maintaining the physical and mental well-being of pregnant women. This activity helps reduce common discomforts such as back pain, enhances stamina, and strengthens pelvic muscles in preparation for childbirth. However, knowledge among pregnant women regarding safe and effective exercises remains limited. The lack of structured information often leads to uncertainty and discourages participation in physical activities during pregnancy. This condition highlights the need for well-directed and comprehensive physiotherapy education. This community service program was conducted in Building B of the Kedungkandang Community Health Center and involved 15 participants. A holistic approach was employed, combining interactive counseling to convey the theoretical benefits and safety of exercise, group discussions to share experiences, and practical demonstrations. The exercises demonstrated were carefully selected to be simple, safe, and easy to perform independently at home, ensuring continuity beyond the educational sessions. The results indicated a significant improvement in participants’ knowledge, as evidenced by the comparison between pre-test and post-test scores. This improvement reflects the growing awareness among pregnant women of the importance of maintaining fitness through structured and safe physical activity. Continuous education through a community physiotherapy approach is necessary to ensure consistent implementation of prenatal exercise and to support long-term behavioral changes toward better maternal health.

High-rise buildings such as the World Trade Center Jakarta generally have high inductive electrical loads, so that their reactive power consumption is large and the power factor decreases below the SPLN standard (≤0.85), resulting in increased power losses and operational costs. This study aims to measure the power factor value before and after repairing the detuned reactor and capacitor on the capacitor bank panel, compare the results of field measurements with ETAP simulations, and assess the feasibility of the installed capacitor bank and determine the difference in the results of the ETAP simulation between measurements and load calculations on the World Trade Center building. The methods used include literature review, field observations on the LVMDP panel, MCC and capacitor bank, discussions with supervisors, data collection of current, voltage, kW, kVAR, kVA and cos φ using Lovato DCRG8 and ampere clamp, and load simulation using ETAP software. The results show that the cosφ value increased from 0.70 to 0.95 (an increase of 35.71%), the compensated reactive power reached 204 kVAR (Lovato), 282.6 kVAR (tang ampere), and 415 kVAR (ETAP simulation), with a power factor or cosφ = 0.95. In conclusion, the replacement of detuned reactors and capacitors effectively improves the power factor in the WTC Jakarta Building, reduces reactive loads, and the ETAP simulation results are consistent with field measurements, so that the capacitor bank installed in the WTC building is declared effective in reducing reactive currents, thereby reducing kVAR, kVA loads and improving the efficiency of the electrical system distribution for better energy management

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.
