2025-11-18T09:19:09+00:00

A green home is defined as a residential concept designed with attention to the principles of sustainability in design, starting from energy efficiency, water management, selection of environmentally friendly materials, to the creation of good indoor environmental quality. The development of green housing in Padang city has begun to increase over time, but the success of a green home housing is indicated by the level of satisfaction of its residents. This study aims to identify and analyze the level of satisfaction of residents of residential houses with a green home concept. Data were collected based on a questionnaire survey and used the Customer Satisfaction Index (CSI) method to analyze the level of satisfaction of residents. Natural lighting, air circulation in the house and comfortable room temperature, design with efficient use of energy and water, the availability of green open space, noise control, waste management, and the use of quality and environmentally friendly materials are the main factors that influence the level of satisfaction and are important for residents of residential houses with a green home concept. The results of the CSI calculation of the three green home concept housing surveyed were 76.69% which is interpreted as a "satisfaction" level although there are still shortcomings in certain aspects that are used as evaluation material for improving the quality of green home housing and the expectations of residents in the future.

Integrasi Autodesk Revit Dan Plugin Sofistik Dalam Penerapan BIM Untuk Efisiensi Pembuatan Bar Bending Schedule (BBS)

2025-11-18T09:19:12+00:00

The application of Building Information Modeling (BIM) is increasingly important in the construction industry because it can improve efficiency, accuracy, and collaboration. One aspect that is greatly influenced by BIM is the preparation of the Bar Bending Schedule (BBS), a detailed document regarding the quantity, dimensions, shape, and weight of steel reinforcement in reinforced concrete elements. Manual preparation of the BBS tends to be time-consuming and produces significant waste material due to suboptimal cutting. This study aims to analyze the application of Autodesk Revit integrated with the Sofistik plugin in creating the BBS and compare it with conventional methods. The case study was conducted on the construction project of the Lecturer Room Building and Multipurpose Room of the Faculty of Cultural Sciences, Andalas University. Data were obtained from Detailed Engineering Drawings (DED), material specifications, and interviews with contractors. The research stages include three-dimensional structural modeling, verification with clash detection, reinforcement modeling, BBS creation using Revit–Sofistik, and optimization of 12-meter-long reinforcing bar cutting using Excel Solver. The research results show that conventional methods require five to six weeks, while Revit–Sofistik only takes three weeks, or even two weeks, from the reinforcement stage to the BBS output, with a time efficiency of 45–66 percent. Bar cutting optimization can reduce material waste to below three percent. These findings prove that the Revit–Sofistik integration can accelerate the BBS process while reducing material waste, even though the cutting optimization function is not yet fully integrated into the BIM flow.

Stabilisasi Tanah Gambut Dengan Geopolimer Hibrid Abu Terbang Dan Pasir

2025-12-06T22:40:43+00:00

Peat soil has high water content and compression, and low bearing capacity. Peat soil stabilization is carried out to increase the bearing capacity, increase the density and strength of the soil. Geopolymer material is one of the materials for soil stabilization derived from basic materials activated with activator solutions such as sodium hydroxide and sodium silicate. This study aims to examine the unconfined compressive strength, average water content, and dry density of peat soil stabilized with a hybrid geopolymer mixture of fly ash and sand. The parameters studied were NaOH molarity of 10M, 12M, and 14M, and silicate modulus (Na2SiO3/NaOH ratio) of 1.5; 2.0; and 2.5. The results of the study showed that the highest unconfined compressive strength was obtained for a mixture with a silicate modulus of 2.5 (GP-12M-Ms2.5), which was 23.68 kPa at 28 days. Unconfined Compressive Strength (UCS) testing was conducted after the samples were cured for 7, 28, and 56 days. The unconfined compressive strength of the GP-14M-Ms2 mixture with a molarity of 14M was 23.68 kPa at 28 days. This is due to the geopolymerization reaction that releases OH- ions to dissolve silica and alumina in fly ash, and the silicate modulus (Ms) can increase the pH of the geopolymerization and bind soil particles better. The highest dry soil content was produced by the GP-12M-Ms2.5 mixture for 7, 28, and 56 days. Sand used in peat soil stabilization can help increase density because it can fill soil cavities.

Analisis Pengaruh Posisi Dinding Geser Terhadap Kapasitas Seismik Struktur Gedung Beton Bertulang Dengan Metode Analisis Pushover

2025-12-09T01:21:43+00:00

Indonesia is an earthquake-prone area, so a building structure capable of resisting lateral loads effectively is required. This study aims to analyze the effect of shear wall position on the seismic capacity of reinforced concrete building structures. The research method uses non-linear static analysis (pushover) using SAP2000 software with four model variations: Model 1 without shear walls, Models 2 and 3 with shear walls parallel to the Y axis, and Model 4 with shear walls installed diagonally at two corners of the structure parallel to the X and Y axes. The results show that the addition of shear walls significantly reduces inter-story drift by up to 71.52% and significantly increases the structural capacity. Model 1 (without shear wall) has a basic capacity of 17,886.10 kN (X direction) and 17,597.82 kN (Y direction), while Model 4 (with diagonal shear wall) shows the highest capacity of 41,074.77 kN (X direction) and 29,242.09 kN (Y direction), with an increase of 229.64% in the X direction and 66.18% in the Y direction, making it the most effective configuration among the three models with shear wall. The configuration in Model 4 produces a balanced stiffness distribution in both main directions, with relatively uniform spectral acceleration (Sa) values in the X (0.57 g) and Y (0.51 g) directions. Based on the ATC-40 performance analysis, Model 1 reaches the Damage Control (DC) level indicating that the structure is still considered safe with maintained stability, while Model 4 reaches the Immediate Occupancy (IO) level, indicating a significant performance improvement. Based on the research results, the placement of shear walls diagonally at two corners of the structure (parallel to the X and Y axes) as in Model 4 can increase the stiffness and capacity of the structure, and also improve the level of seismic performance even though it can reduce ductility. The Model 4 configuration is effective in distributing earthquake forces evenly and creating a more balanced structural system compared to other models.

2026-02-06T07:53:07+00:00

The increase in traffic in Indonesia is in the form of increasing volume and weight of vehicles. Good road construction quality is needed, namely high stability. Additives in asphalt mixtures are used to improve the quality of the mixture. One form of additive that can be used is cellulose fiber found in cigarette filters. Cigarette filters produce waste that has an impact on the environment. This study aims to determine the effect of cellulose acetate fiber from cigarette filters and its optimum content in the AC-WC (Asphalt Concrete Wearing Coarse) mixture. The Marshall method was used in this study. Cigarette filter waste of 3%, 5%, 7%, and 9% was added to the asphalt. The results of the study were an optimal percentage of cigarette filter waste of 7%, with a stability value of 2804.14 kg and an MQ value of 477.26 kg / mm. The addition of cigarette filters to asphalt resulted in an increase in the specific gravity value and a decrease in the asphalt penetration value.

Analisis Numerik Kapasitas Geser Dinding Geser Pelat Baja Dengan Bukaan Untuk Rasio Lebar–Tinggi Panel (B/H ≥ 1)

2026-02-06T07:53:05+00:00

Steel Plate Shear Wall (SPSW) is a lateral force resisting system developed as an alternative to reinforced concrete shear walls, especially in multi-storey building structures. The presence of openings in the plate panel, such as for building access and utility needs, has the potential to reduce the structural capacity and change the force transfer mechanism. Therefore, this study aims to evaluate the effect of openings on the shear capacity and stress distribution of steel plate shear walls with a panel geometry ratio of B/H ³ 1. The study was conducted through finite element-based numerical modeling. Variations in the B/H ratio were analyzed by maintaining the same percentage of openings, while lateral loading was given by displacement control until it reached a drift of 4% of the panel height. Load-displacement data and stress contours were obtained as the main results to evaluate the structural response to lateral loads. The simulation results show that although the presence of openings triggers stress concentration in the opening corner area and affects the distribution of diagonal tension mechanisms, the shear capacity in panels with a B/H ratio ≥ 1 still increases. This condition is caused by the wider panel geometry, so that the remaining effective plate area is still able to withstand lateral forces and maintain stable shear force transfer. In addition, shear walls with B/H > 1 exhibit a wider diagonal strain pattern distributed in both directions, thus reducing the stiffness reduction due to openings.

The use of practical methods in calculating the dynamic response of soil due to the propagation of earthquake waves in soil deposits and their impact on the structure above it is presented in this paper. Practical methods are commonly used in preliminary design to estimate the ideal structural dimensions from the available data obtained from field and laboratory investigations before being further processed in detail with engineering programming tools. In this paper, calculations are carried out referring to tables published in SNI-1726 and reference paper tables. A case study was conducted on a sloped embankment against seismic loads on a medium soil class (Sd) site. The results obtained are a mapping of the slope safety factor due to selected earthquake accelerations that are applied to the structure.
