Abstract

Landslides occurred continuously from July 2022 until July 2023, disrupting the construction of the Bagong Dam abutment. Geologically, the foundation of the Bagong Dam consists of a fairly thick colluvial layer, which is prone to landslides. So, the analysis of landslide mitigation at the Bagong Dam abutment is needed. The slope stability analysis carried out by Fellenius and Bishop method, then the slope modeling was carried out using Geostudio software. The analysis results on the existing slopes produced a safety factor of 0.987 (<1.07) for the Fellenius method and 1.042 (<1.07) for the Bishop method. These safety factors indicate that the existing slope is unstable and slope failure is likely to occur. In the first alternative countermeasure analysis, the slope safety factors for the cross-section of the dam at STA 0+625 were 1.715 for upstream and 1.338 for downstream; at STA 0+641, 1.321 upstream and 1.306 downstream; and for the longitudinal section of the dam, 1.525. All these safety factors greater than 1.25, indicating that the slope is stable. In the second alternative countermeasure, the slope safety factors obtained for the cross-section of STA 0+641 were 1.362 for upstream and 1.386 for downstream, and 1.657 for the longitudinal section. These safety factors are also greater than 1.25, which indicates the slope is in stable condition. The additional cost for implementing the first alternative countermeasure is 73.9 million, while for the second alternative is 35.7 million. So that, the second alternative countermeasure is the best choice by the multi-criteria decision-making analysis results.

Abstract

The high population density and mobility in the Yogyakarta Urban Area necessitate the improvement of transportation services. The current population density in Yogyakarta is approximately 13,007 people per square kilometer, and the city experiences significant daily commuter traffic. Problems occur because the available modes of transportation have several limitations. While the existence of stations/airports/terminals requires connectivity from other modes of transportation. Ride-hailing services have emerged as a convenient and practical solution for users. However, the integration of ride-hailing services with multimodal systems, particularly for first mile and last mile trips, is still considered inadequate, and there is limited empirical evidence on this matter. Therefore, conducting an in-depth study is crucial to comprehend users' perceptions of ride-hailing for first mile and last mile trips. Primary data collection was conducted by face-to-face and online using Google Form on 416 respondents. The primary data collection technique was carried out using the convenience sampling method. The data collected consists of socio-demographic data, travel characteristics and variables that influence respondents to use ride-hailing for first mile and last mile trips. This research uses descriptive analysis, and exploratory factor analysis, by employing exploratory factor analysis, the results reveal that there are 2 factors that influence respondents to choose to use ride-hailing, namely convenience and practicality and service performance. Convenience and practicality refer to the ease of service, including payment and ordering, and the ability for ride-hailing services to pick up or drop off users at home. Service performance includes short waiting times, certain travel times, comfort, and safety. Improving these aspects could enhance the integration of ride-hailing services with existing transportation systems, addressing current inadequacies.

Abstract

The existence of evacuation routes is one of the most important elements in disaster management because it will determine the smoothness of the rescue process during a disaster. An evacuation route is a route to an assembly point or exit that is assumed to be a safe space. Wayfinding is the process of moving from one point to another within the closest or fastest distance. In relation to the evacuation process, wayfinding will show the movement from a point, which in relation to buildings can be a specific space, to an exit or assembly point. As one of the disaster preparedness schools in Yogyakarta's Special Region, Masjid Syuhada Kindergarten was chosen as the site of the research. It is a complex of schools ranging from playgroup, kindergarten, elementary school, to junior high school, all of which are connected by the Syuhada Mosque.  The analysis of evacuation routes in the kindergarten was conducted using Urban Network Analysis (UNA). UNA is used as a method to determine the effectiveness of providing evacuation routes in a building area because it can analyze trips between points, called origin and destination. Of the various analyses that UNA can perform, this research uses the closest facility analysis. In this study, the origins were all the class in the kindergarten which placed at the door as the open access and in the middle of the class if the class have two doors; while the destinations were the stairs which heading to assembly point. The conclusion is reached after analyzing the network that connects the origin of the class to the destination of the stairs, which is connected to the assembly point.

Abstract

Virtual materiality has become a reality due to technological advancements. This affects the evolution of architecture. Land utilization in residential designs is currently unrestricted. Humans still exploit natural land and food supplies to build homes. Conversely, houses that merely use the land for viewing rather than traversing it are an example of inefficient land usage. In architecture, virtual materiality plays a part in creating an artificial world. In order to minimize land consumption, an architectural strategy that may introduce virtual materiality into the real world is required. Illusion is one tactic. Tricks and deceit are given priority in the illusion technique. This program is intended for home users who want to replace their natural surroundings with an artificial one. By using this method, nature can improve without requiring interference from the original environment. Modeling experiments and qualitative research are used in the research methodology. Create suggested concepts by using an architectural methodology. Rendering models and sketches are the research outputs. The findings demonstrate that home design can make use of illusion as a representation of virtual materiality. Through the application of matter illusion techniques, manufactured environments can be made to resemble natural ones. Implementing the material illusion in a trapezoidal home. Screen technology is used to do this. The center of the design is where screen technology is used to display environmental content. big horizontal and vertical sides are necessary. However, this can be a substitute for the natural environment for residents, especially in dwelling design.
