Abstract

Public buildings are structures used to serve the activities of the community at large. These buildings become gathering places for many people at one time. As venues for community activities, the presence of public buildings in tsunami-prone areas can increase vulnerability for their users. Therefore, it is necessary to understand the characteristics of public buildings located in regions at risk of tsunamis. This study aims to determine the reliability of public buildings based on the distribution of building zones, building structures, building heights, and the orientation of building locations. The results show that there are 328 public building units spread across the study area, which have varying levels of tsunami risk from low, medium, to high. The percentage breakdown of building classifications includes government buildings (31.1%), educational facilities (40.5%), health services (6.1%), places of worship (17.1%), commercial buildings (2.1%), and other facilities (3.0%). In terms of zone distribution, public buildings are predominantly located in alert zones that have a high risk of tsunami disasters. The building structures are generally permanent, made of reinforced concrete, with the majority being two or three stories high. The buildings are distributed across sparse, medium, and dense locations. Buildings with good reliability characteristics, such as strong structures resistant to tsunami waves and medium to high building heights, can be considered as alternative vertical evacuation sites for tsunamis. In Banda Aceh, public buildings are mostly low-rise, while medium-rise buildings include office and health service buildings. To ensure safety and security, it is necessary to enhance the quality of public buildings in the future, especially in areas with high tsunami risk.

Abstract

The research method was carried out through a survey of a number of buildings in the coastal area of Banda Aceh City. The analysis was carried out by comparing the floor heights of buildings with the historical height of the tsunami that occurred in 2004. Based on the survey results, it was found that there were 319 public buildings spread across the coastal area of Banda Aceh City. The percentage of each is known by the number of government office buildings (31.7%), educational facilities (40.8%), health services (5.6%), places of worship (16.6%), trade (2.2%), and other facilities (3.1%). From the analysis of building floor heights, a total of 194 buildings, or 60.81% of the total existing public buildings could function as alternative vertical evacuation sites for the tsunami disaster. This amount can accommodate 43.95% of the total population living in the surrounding area. Thus, part of the population can carry out vertical disaster evacuation. While others are planned through horizontal evacuation scenarios. Public buildings designated as vertical evacuation sites are only calculated from the safe height of the building floor. In contrast, in terms of the resilience of the building structure, it can be re-evaluated.

Abstract

This Community Service Program (PKM) aims to provide early disaster education to kindergarten children in disaster-prone areas. Utilizing an interactive approach through play and singing, this program imparts foundational knowledge about earthquakes and volcanic eruptions, along with essential self-rescue steps. The program also benefits teachers by enhancing their skills in delivering disaster education to young children, and it supports schools in incorporating educational disaster-related games into annual activities. The results indicate that this enjoyable and participative learning approach effectively improves children’s understanding and preparedness for potential disasters. Additionally, the program fosters a disaster-aware culture within the school environment, with the hope that it can be replicated in other schools located in high-risk areas.

Abstract

Coastal tourist destinations located in tsunami-prone areas exhibit high vulnerability to disasters, particularly given the number of tourists unfamiliar with local hazards and evacuation procedures. This study aims to develop effective evacuation routes in coastal tourist areas to mitigate the risk of casualties and losses due to tsunamis. The method used in this research is a case study with a spatial analysis approach, where existing evacuation routes are evaluated based on accessibility, travel time, and safety for tourists. Data were collected through field surveys, interviews with local stakeholders, and simulation-based evacuation modeling. The results show that there are six evacuation routes leading to vertical evacuation shelters on Lampuuk, Lhoknga, with two of the routes exceeding the safe evacuation time limit. The current evacuation routes are insufficient due to a lack of signage, routes that are not easily accessible for tourists, and reliance on vulnerable infrastructure. Therefore, new evacuation routes need to be developed, taking into account evacuation distance, topography, visitor behavior, and local community participation in the planning process to strengthen the resilience of tourist destinations against tsunami threats.

Abstract

The material supply chain is a material distribution flow that varies from various sources or suppliers, until the material arrives at the project site. This study aimed to analyze material supply chain risk factors that arise in the implementation of building construction projects in Aceh Province, as well as identify solutions to prevent material supply chain risk factors that arise in the implementation of building construction projects in Aceh Province. The methods developed in this research are validity test, reliability test, quantitative descriptive, and multiple regression analysis through SPSS software version 25. From the validity test results obtained, the value of Rcount ≥ Rtable. This shows that the validity test performed on all questions is valid. Furthermore, the results of the reliability test obtained the average value of each variable of 0.708, then the reliability test was said to be reliable. Because the value of a variable is said to be reliable (reliable) if Cronbach Alpha value exceeds 0.6. Then from the results of the descriptive analysis, there are indicators that are often questioned as risk factors, namely the delay of the main contractor in paying subcontractors (X2.8) with a mean value of 3.39. This shows that the majority of respondents stated that X2.8 has a high influence on the occurrence of material supply chains in the implementation of construction projects. From the results of the correlation analysis, the R value of 0.382 (low/weak), then the two variables have a unidirectional relationship. This means that if the value of the X variable is high, then the value of the Y variable will also be high or if it means that all X variables are related to material supply chain risk, and the regression model obtained is: Ŷ=7.408+0.096X1-0.006.X2+ 0.132X3+0.112X4. From the results of the coefficient of determination, the value of R2 = 14.6%, which means that the risk of the material supply chain is influenced by supply factors, control factors, demand factors, process factors, amounting to 14.6%, the remaining 85.4% is influenced by other factors variables which are not included in this study.

Abstract

Projects of building construction develops acordance with the implementation of the fulfillment of human life. During implementation, the project did not always as expected. These things happen due to cost and time deviations. The problem in this research is what are the factors that cause cost overrun and time overrun in the implementation of building construction projects in Banda Aceh city. The purpose of the study was to determine the causes of cost overrun and time overrun in the implementation of building construction projects toward minimize the impact of failure in the implementation of a construction project. The research data was obtained by distributing questionnaires to 40 respondents from qualified (small) and (medium) of contractors in Banda Aceh city. The sampling technique used is purposive sampling with the criteria of fulfilling the experience of having been involved in the implementation of building construction projects. Data processing was carried out with SPSS version 24 software with confirmatory factor analysis, descriptive analysis and fishbone analysis. The results of factor analysis obtained the average value of the MSA test of 0.694, the KMO test of 0.684. The value of a variable can be analyzed further if the value exceeds 0.5 and the Bartlett test obtained a value of 0.000 <0.05, it explaned each variable is correct. The total value of variance explained is 50.91%, it means the nine factors can form the factors causing cost overrun and time overrun, while the remaining 49.08% is explained by other factors. From the loading factor value, the dominant factor is material factor (X4) with a loading value of 0.91. The results of the descriptive analysis show causing of cost overrun and time overrun are an increase in material prices (X4.3) with mean value is 4.13 and poor quality control of materials (X4.4) with mean value is 4.03.

Abstract

People who lived on the Banda Aceh City shoreline lost their houses in the 2004 tsunami tragedy. The likelihood of a tsunami tragedy in the future might rise if homes are rebuilt in the original location. The goal of this study was to determine the most common building types and the degree of susceptibility of residential structures to the tsunami catastrophe in the districts of Kuta Alam and Syiah Kuala. Through a sample approach, a questionnaire was given out to the community in the districts of Kuta Alam and Syiah Kuala, with a total of 105 responses. To gather representative home building types at the research site, a survey was undertaken. data processing with the use of the validity and reliability tests in SPSS. The questionnaire was deemed legitimate as a result of the validity test, which produced average R count values of 0.1918 and higher than the value of r table. The reliability test findings were dependable since they had a Cronbach Alpha score of 0.671, which is higher than 0.6. The predominant home types in the Kuta Alam and Syiah Kuala subdistricts are type B (good) and type C (poor) dwellings. Low, medium, and high levels of vulnerability were used to determine how vulnerable residential buildings were to the tsunami tragedy in the Kuta Alam District. The Syiah Kuala District, meanwhile, had high and moderate degrees of vulnerability. According to the physical state of the environment in the districts of Kuta Alam and Syiah Kuala, 19% of the coastal regions are still in their original state, and 81% of the territory is made up of grib stones and mangroves. In the Kuta Alam sub-district, there are 11 villages overall, with the percentage of vulnerable structures falling into one of three categories: low (45.45%), medium (45.45%), or high (9.09%). In the Syiah Kuala District, however, the degree of vulnerability of residential structures was determined from a total of 10 villages, and it was divided into two classes: medium, with a percentage of 40%, and high, with a percentage of 60%. As a result, it's important to upgrade the design of communal housing in coastal locations, such as by constructing homes with two or more levels.

Abstract

Pelaksanaan proyek konstruksi memerlukan penjadwalan yang terstruktur guna meminimalkan risiko keterlambatan. Penjadwalan proyek berperan penting dalam merinci progres pembangunan dari aspek durasi, anggaran, kinerja, tenaga kerja, material, hingga peralatan. Dalam praktiknya, sering muncul risiko keterlambatan akibat faktor-faktor tak terduga. Penelitian ini bertujuan untuk menganalisis struktur jaringan kerja serta membandingkan durasi dan biaya proyek sebelum dan sesudah dilakukan percepatan menggunakan metode Critical Path Method (CPM). Metode ini digunakan untuk mengidentifikasi aktivitas-aktivitas utama yang menentukan waktu penyelesaian proyek dan untuk mengevaluasi fleksibilitas dalam penjadwalan. Penelitian ini menggunakan pendekatan campuran (kuantitatif dan kualitatif) dengan teknik analisis deskriptif dan komparatif. Data yang dianalisis mencakup time schedule dan Rencana Anggaran Biaya (RAB), yang menjadi acuan dalam membandingkan kondisi awal dan hasil percepatan proyek. Temuan penelitian mencakup penyusunan Work Breakdown Structure (WBS), penetapan kode kegiatan, identifikasi ketergantungan antar pekerjaan, perencanaan jaringan kerja, penentuan lintasan kritis, serta strategi percepatan melalui penambahan sumber daya kerja dan evaluasi pembiayaan. Hasil analisis menunjukkan bahwa penerapan metode CPM mampu mengurangi durasi proyek sebesar 42 hari (10,769%), dari semula 364 hari menjadi 322 hari, tanpa menimbulkan peningkatan biaya, yakni tetap sebesar Rp. 8.055.013.628,53. Dengan demikian, metode CPM terbukti efektif dalam mengoptimalkan penjadwalan dan pengendalian waktu pelaksanaan proyek konstruksi melalui identifikasi lintasan kritis.
