Abstract

Structural analysis requires modeling using computer programs, one of which is OpenSees which uses TCL the one-line commands for modeling, analysis, material properties and other aspects. The lack of a GUI that makes users friendly in OpenSees can cause modeling errors. In this research, the Octave-based RCstructureMDL program was developed for automatic modeling of reinforced concrete structures on OpenSees. Three models with variations in the number of floors and frames in the X and Y directions are used to test the flexibility and the correctness of the model. Flexibility can be seen from the ease of creating modeling commands from three models by changing the variables nX, nY, nf, span_X, span_Y, and storey_Z. Support reaction value shows the same value as the vertical and horizontal load entered at all top floor points, so the model generated automatically using this program can be used for analysis.

Abstract

Raknamo Dam is a dam that has a storage capacity of 14.091 million/m3 of water with the aim of providing raw water, providing irrigation, developing tourism, freshwater fisheries and freshwater conservation, flood control and hydroelectric power generation (PLTA). This study aims to analyze how much elevation of water level drop and the amount of discharge that comes out (outflow) when flooding occurs if the early release model is applied as a flood controller with a scheme of utilizing the use of water pumps. From the results of the analysis with the early release scheme as a flood controller, the scenario used is the utilization of the use of water pumps for 5 days, 3 hours with a total of 4 submersible pumps calculated, each with a capacity of 6 m3/sec, so that it can reduce flooding in the 1000-year return period with a scheme of 1 pump unit with a discharge of 378.60 m3/sec from an elevation of +107.2 m to 106.9 m; scheme of 2 pump units with a discharge of 288.60 m3/s from elevation +107.2 m to +106.4 m; scheme of 3 pump units with a discharge of 198.60 m3/s from elevation +107.2 m to +105.9 m and scheme of 4 pump units with a discharge of 108.60 m3/s from elevation +107.2 m to +105.3 m.

Abstract

Indonesia is a country with various ethnicity and culture. One with the most population compared to another foreign ethnic is Chinese. This results in the existence of so many buildings influenced by Chinese architecture, such as: houses, temples, schools and others. It’s quite intriguing how school design is using Chinese architecture, considering that it is a public facility which has fixed facilities, and strictly monitored by government’s regulation. This is the main reason of choosing Tzu Chi school as a case study in this research. The goal of doing this research is to know which Chinese architecture character is used in the building design. The research variables are: roof, door, window, column and stairs. The research method is qualitative-descriptive, by comparing the variables of the case study with the reference, and then describing the observation in narrative manner. Based on the research, it is concluded that Tzu Chi school is implementing Chinese architecture in its design.

Abstract

The exploration of design themes and concepts is a crucial part of the architectural design process, as both elements shape the characteristics, philosophy, and meaning of an architectural work. Understanding themes and styles poses challenges for designers, particularly in balancing local context with functional, aesthetic, and technological needs. The theme serves as a conceptual direction, while style represents the visual, cultural, and historical expressions of a building. However, confusion between “theme” and “concept” often leads to misapplication, hindering the creation of clear design ideas and objectives. Therefore, a deep understanding of these elements is essential to ensure that design outcomes align with their intended goals and communicate effectively with users. This study aims to examine how architectural themes are applied in design practice through a case study of the Babah Alun Mosque in Cilandak, South Jakarta. The mosque adopts a Chinese architectural theme that is acculturated with Islamic culture, resulting in a unique formal and symbolic expression. This study is expected to enrich the understanding of how themes and concepts interact within architectural design methodologies and contribute to shaping cultural identity in contemporary architectural works.

Abstract

Studies that investigated the effectiveness of groundnut mixing as a function of mixing speed and time are scarcely reported. Therefore, the objective of the study is to investigate the main and interaction effects between additive and speed on the mixing evaluation parameters, with respect to different mixing proportions of ginger, wheat flour and pepper. The mixing parameters for evaluating the mixer are; degree of mixing, percentage loss and mixing efficiency. The components of the mixer consist of the frame, the U-shaped trough, a central shaft and a helical ribbon agitator. The coating unit consists of coating trough, drive shaft and electric motor. The highest values of the degree of mixing and mixing efficiency recorded were 92.23 and 99.75% respectively. The efficiency of mixing increases as mixing time increases. Similarly, increased performance in mixing was observed as the mixing speed increases. The main and interaction effects between the additive and speed were insignificant (P > 0.05). The highest speed of 60 rpm and mixing time of 15 mins produced the highest mixing efficiency.

Abstract

The Moment-Resisting Frame System (MRFS) equipped with shear walls shows a significant increase in structural stiffness compared to systems without shear walls. The results of the inter-storey drift analysis confirm that the presence of shear walls reduces the horizontal deformation of the building, thereby increasing lateral stability. In addition, the use of shear walls contributes to the efficiency of reinforcement requirements, as seen in the column reinforcement ratio of 3%, which is lower than that of structures without shear walls, which reaches 5%. Although the mass of the structure with shear walls is greater, namely 4747.96 kN compared to 3853.08 kN in structures without shear walls, this system still offers advantages in terms of more efficient use of main reinforcement. Overall, the integration of shear walls in the frame system provides better structural performance through increased stiffness, reduced deflection, and optimised reinforcement requirements.

Abstract

The development of geospatial technology has enabled more efficient analyses of urban density. Google Maps API provides location data, traffic information, and user activity patterns that can be utilized to detect density levels in urban areas. This study aims to explore the potential of the Google Maps API as a tool for identifying urban density by integrating traffic data (Traffic Layer), business location datasets, and user movement patterns. The findings indicate that data obtained from the Google Maps API can be used to map high-density zones in both real-time and historical contexts. These insights have significant implications for urban planning, congestion mitigation, and smart city development.
