Determination and Implementation of the Shortest Path for Emergency Evacuation at the Bali Dwipa University Building: A Case Study
Get PDFThis study applies the Floyd Warshall Algorithm to determine the shortest emergency evacuation route in the Bali Dwipa University building. An efficient and fast evacuation route is essential to ensure the safety of all building occupants. This study was conducted at Bali Dwipa University, Denpasar, Bali, to evaluate and map the building layout to the third floor as part of the evacuation system analysis. The research methodology involves collecting primary and secondary data and direct manual measurements in the field. The research stages begin with creating a building plan, which includes collecting information on the layout and existing evacuation procedures. Furthermore, using a precision measuring instrument, mapping the relationship between objects is carried out with manual measurements of the distance between rooms to determine the evacuation route to a safe point. The results of these measurements are analyzed to build a spatial structure by selecting the nodes and edges in the graph that represent the building. Then, the Floyd-Warshall algorithm is implemented to find the shortest path from each room to the gathering point, located in the first floor's lower front yard. The study results indicate that applying the Floyd-Warshall algorithm effectively determines the shortest path from each node in the Bali Dwipa University building to the main evacuation point. By mapping the nodes from the 1st to the 3rd floor and measuring the distance between the nodes, this study produces a clearly defined optimal evacuation route. This study is expected to improve the efficiency of evacuation routes and the safety of occupants in emergencies
Modelling Water Absorption Index and Compressive Strength of Paving Stone Composites with Polyethylene Terephthalate (PET) as Total Binder Replacement
Get PDFPolyethylene terephthalate (PET) wastes were melted and mixed with river sand to produce paving stone composites (PSCs) of mix ratio 1:3, labelled (PET: 10, 20, 30, 40, and 50%); and sand-cement mix of 1:3 labelled PET 0% (control). In a mold measuring 50 × 100 × 200mm, three replicates of PSCs of each mix ratio and control, were produced and cured in water at a room temperature of (27 ± 2ºC) for 28 days. The PSCs showed a better water absorption property as it ranges from 6.98 % to 3.59 % as against 11.11 % for the control. Significant compressive strengths were shown by the PSCs; PET 30% had the highest mean value of 20.59 N/mm2, while the control had the lowest mean value of 8.63 N/mm2. Using Design Expert tool in analyzing the laboratory data obtained for both water absorption index and compressive strength, the results show that the developed quadratic model for water absorption index (WAI) has an adjusted and predicted coefficient of regressions of 0.9851 and 0.9821 respectively, with an average precision of 98.62% within the research work, allowing for simulation of WAI outcomes at different PET contents. Also, the compressive strength model is a quadratic, with adjusted and predicted coefficients of regressions of 0.9623 and 0.9526 respectively, and shows reduced variation between actual and predicted values, making it useful for design space navigation. The research suggests that utilizing PET waste as a complete binder replacement in paver production is a cost-effective method for managing wast

This school is also expected to function as a center for developing air combat tactics and strategies and providing comprehensive training for all Indonesian Air Force pilots. With the establishment of this school, synergy will be created between various air power units to strengthen the combat capability of the Indonesian Air Force in maintaining Indonesia's air sovereignty. It is hoped that the Indonesian Air Force can immediately establish an air combat school that focuses on developing the operational capabilities of pilots through realistic exercises and international collaboration
A Review: Speech Separation Techniques and Its Applications
Get PDFA fundamental task in signal processing, speech separation has many practical applications. For example, it can be used to improve the accuracy of automatic speech recognition by separating clear speech from noisy speech signals. When all that is available is a monaural recording of mixed speech, the task of extracting distinct sources from a complex mixture appears to be challenging for automatic calculation systems, in contrast to the remarkable ability of the human auditory system to do so. Monaural speech separation poses numerous challenges, but over the years, numerous attempts have been made in prior works to address this issue. Within the study that is being presented, we offer an extensive analysis of current research on speech separation and its uses
