Abstract

Buildings subjected to horizontal vibration loading can cause displacement deformation and even collapse. Laboratory-scale testing to simulate vibrations due to horizontal loading can be done using structural modeling using a shaking table as the vibration source medium. This can be done because large-scale testing is very difficult to do due to cost and time constraints. This study aims to analyze the impact of bracing use on the response of Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) structures due to horizontal vibration loads. The building models tested were one to three-story models with and without bracing. Testing was carried out using a one-way horizontal shaking table with varying frequencies of 15 Hz, 20 Hz, and 25 Hz to see the differences in each structural response. The parameters observed in this study were model displacement and acceleration. The study results show that the model without bracing experiences a maximum acceleration at each vibration table frequency of 490 cm/s2 with a vibration table frequency of 15 Hz, 649 cm/s2 with a vibration table frequency of 20 Hz, and 774 cm/s2 with a vibration table frequency of 25 Hz. Meanwhile, the model using bracing experiences the largest acceleration reduction of up to 35% for a vibration table frequency of 25 Hz. Bracing increases the lateral stiffness of the structure thereby reducing deformation to be smaller than the structure without bracing. The maximum displacement value of the model without bracing at each frequency is 1.08 cm at a vibration table frequency of 15 Hz, 1.54 cm at a vibration table frequency of 20 Hz, and 2.84 cm at a vibration table frequency of 25 Hz. From the study conducted, it can be concluded that the use of bracing in SDOF and MDOF structures has a reduction in structural response of up to 35%.

Abstract

In reality, a building structure was built floor by floor or gradually, this is going to affectforces in preliminary design (using Direct Loading Method). The most extreme effect in the form ofeccentricities in the column structure, there this research is giving depiction on how far eccentricitiesdeviation dan what factor affects column structure eccentricities as the consequence of gradualbuilding.This research utilizes Sequential Loading Method, that is weight loading method by trying toimitate loading while construction execution occured with loading weight on gradual and sequentialstructre model.Eccentricities on column structure will extremely decrease if axial weight was added(column with one floor above). This research show eccentricites decrease until 26.39% or decrease asmuch as 73.61% from Full Model analysis. Bekisting dismantling before structure column and floorweight above done correctly is the main factor for a extensive eccentricites on column structure tohappen. So, bekisting dismantling should be planned very well by calculating its structure behavior.

Abstract

Sustainable Urban Drainage Systems (SUDS) are considered an innovative approach to urban water management, but their application in Indonesia is still very limited. Aim: This study was aimed to analyze the impact of land use change on runoff coefficient and its implication for socio-economic resilience in post-flood conditions in Kuantan Tengah District, Riau Province. Methodology and results: The research applied a spatial-hydrological and socio-economic approach, integrating drone imagery, GIS-based land classification, runoff coefficient analysis, field drainage assessment, and community surveys. Results revealed that the average runoff coefficient (Cr) increased to 0.57 due to land conversion into impervious surfaces, especially residential and road areas. This condition led to inadequate drainage capacity and contributed to urban flooding. Socio-economic impacts identified include infrastructure damage, income loss in local businesses, health problems, and psychological stress. SWOT analysis highlighted institutional strengths and public awareness, but also emphasized weak ecosystem-based management. Conclusion, significance and impact study: A Sustainable Urban Drainage System (SUDS) model was proposed to overcome these challenges, combining green infrastructure, zoning policy, SOP (standard operating procedures) for drainage maintenance, and community participation. This study provides a novel integrative framework for urban flood risk mitigation based on hydrological and socio-economic indicators and offers policy insights for sustainable spatial planning in flood-prone regions.  The solutions offered directly support several Sustainable Development Goals (SDGs), particularly SDG 11 on Sustainable Cities and Communities, SDG 6 on Clean Water and Sanitation, and SDG 13 on Climate Action.

Abstract

Artificial neural networks (ANN) are now widely used and are becoming popular among researchers, especially in the geotechnical field. In general, data normalization is carried out to make ANN whose range is in accordance with the activation function used. Other studies have tried to create an ANN without normalizing the data and ANN is considered capable of making predictions. In this study, a comparison of ANN with and without data normalization was carried out in predicting SPT values based on CPT data and soil physical properties on cohesive soils. The input data used in this study are the value of tip resistance, sleeve resistance, effective soil overburden pressure, liquid limit, plastic limit and percentage of sand, silt and clay. The results showed that the ANN was able to make predictions effectively both on networks with and without data normalization. In this study, it was found that the ANN without data normalization showed a smaller error value than the ANN with data normalization. In the network model without data normalization, RMSE values were 3.024, MAE 1.822, R2 0.952 on the training data and RMSE 2.163, MAE 1.233 and R2 0.976 on the test data. Whereas in the ANN with data normalization, the RMSE values were 3.441, MAE 2.318, R2 0.936 in the training data and RMSE 2.785, MAE 2.085 and R2 0.963 in the test data. ANN with normalization provides a simpler architecture, which only requires 1 hidden layer compared to ANN without normalization which requires 2 hidden layer architecture.

Abstract

Indonesia is one of the countries that located in the quake zone. But not all earthquakes that occur is a devastating earthquake. Some earthquake parameters that affect the level of damage from a building structure are the peak ground acceleration, response spectrum value, earthquake duration, and earthquake frequency content. The earthquake frequency content parameters were considered the most influential on structural damage. The objective of this research is to get the response from the structure of multilevel steel portals such as displacement, inter-story drift, velocity, acceleration, and to analyze the displacement limit based on SNI 1729-2012. The reviewed structure is an open frame steel building model that is into 5 levels, 10 levels, and 15 levels. This study use time history analyses with 9 earthquake recordings of the Kobe earthquake, Mexico earthquake, Nepal earthquake, Chile earthquake, New Zealand earthquake, Sumatera earthquake, Fredericksburg earthquake, Mentawai earthquake, and Northridge earthquake that has been grouped into low-frequency content, medium frequency content, and high-frequency content. The results showed that the structure responses such as displacement, velocity, and acceleration will increase with the increasing number of levels of the building structure. The inter-story drift the allowed level of the structure still qualified based on SN 1729-2012 where the allowed drift in 7 cm and the inter-story drift produced by the structure is still less than 7 cm. An earthquake with low-frequency content has an enormous influence on the structure response in all the level structure.Keywords: response structure, time history, frequency content

Abstract

Abstrak Kepadatan dan kekakuan tanah merupakan permasalahan yang harus diperhatikan dalam perencanaan struktur bangunan konstruksi. Hal ini disebabkan tanah berperan sebagai media yang menahan beban ataupun aksi dari konstruksi yang akan dibangun di atasnya. Perbaikan tanah dengan mencampurkan dua material merupakan salah satu cara untuk memenuhi kekuatan yang dibutuhkan. Perubahan cuaca dan suhu di lapangan menjadi faktor yang menjadikan tanah tidak stabil. Perbaikan tanah yang dilakukan berasal dari Proyek pekerjaan Tol Pekanbaru – Bangkinang yang berasal dari empat lokasi pengamatan. Penelitian ini dilakukan dengan mencampurkan dua material tanah dengan perbandingan 1:1 dari lokasi yang berbeda. Setelah itu dilakukan pengujian CBR, Berat Jenis, Batas-batas Atterberg dan berat volume untuk setiap benda uji. Hasil penelitian berupa nilai CBR yang menunjukkan bahwa nilai CBR tertinggi berada pada tanah campuran Pasir 2 dengan Tanah 2 dengan nilai CBR 34.34 %. Nilai CBR terendah didapatkan pada campuran Tanah Pasir 1 dengan Tanah 1 dengan 21.5%. Campuran antara Pasir 1 dengan Tanah 2 memiliki nilai CBR 25.3%, sedangkan Pasir 2 dengan Tanah 1 memiliki nilai CBR 24.8% tidak terlalu jauh dengan Pasir 1 dengan Tanah 2. Kepadatan kering maksimum untuk pasir 1 tanah 1 adalah 1.944 gr/cc. Pasir 1 dengan tanah 2 adalah 1.943 gr /cc. pasir 2 dengan tanah 1 adalah 1.996 gr/cc. Sedangkan pasir 2 dengan tanah 2 adalah 1.930 gr /cc. Perbedaan relatif kepadatan kering maksimum dipengaruhi oleh variasi ukuran butiran pada metode kepadatan ringan (standar). Kata Kunci: Nilai CBR, kekakuan tanah, perbaikan tanah, tanah lempung, pasir Abstract Soil density and bearing capacity are problems that must be considered in the planning of construction building structures. This is because the soil acts as a medium that holds the weight or action of the construction to be built on it. Stability by mixing two materials is one way to meet the required strength. The changes in weather and temperature in the field are factors that make the soil unstable. The samples carried out came from the Pekanbaru - Bangkinang Toll Road Project which came from the four observation locations. This research was conducted by mixing two soil materials with a ratio of 1: 1 from different locations. After that, testing the CBR, Specific Gravity, Atterberg limits, and volume weight for each specimen. The results of the study were CBR values which indicated that the highest CBR value was in a mixture of Sand 2 and Soil 2 with a CBR value of 34.34%. The lowest CBR value was found in a mixture of Sand 1 and Soil 1 with 21.5%. The mixture between Sand 1 and Soil 2 has a CBR value of 25.3%, while Sand 2 and Soil 1 have a CBR value of 24.8%. The maximum dry density for Sand 1 Soil 1 is 1.944 Gr/cc. Sand 1 with soil 2 is 1,943 Gr / cc. Sand 2 with soil 1 is 1.996 Gr/cc. While sand 2 with soil 2 is 1,930 Gr/cc. The relative difference in maximum dry density is influenced by grain size and is not influenced by compaction energy and mold size in the light density method (standard). Keywords: CBR value, soil stiffness, soil stabilization, clay soil, sand

Abstract

Quality assurance of higher education is carried out through the determination, implementation, evaluation, control, and improvement of Higher Education Standards (SPT) known as the PPEPP cycle. Each university is expected to be able to develop an SPMI pattern that is appropriate for the conditions of the university itself. However, not all universities have the same understanding of the implementation of SPMI. For this reason, this community service activity aims to help two universities in Kampar Regency, Riau Province, namely: Universitas Pahlawan Tuanku Tambusai and STIE Bangkinang. Although these two universities already have an Internal Quality Assurance Institution, the adequacy of SPMI documents has not been fully met according to standards. The community service activity began by distributing an initial survey on participants' understanding of SPMI at their respective universities. Furthermore, the community service activity was filled with the provision of materials and a final survey to analyze changes in the level of participants' understanding of the material given to participants. The survey results showed that there had been an increase in participants' understanding in compiling and archiving SPMI documents.
