Abstract: UD. Pak Suandi is one of the UDs that produces and sells bricks. Many factors influence the quality of bricks, namely human resources, composition, and processing of raw materials. Brick making sometimes does not match the desired quality, there are often defects/cracks in the bricks. The method used in this research is the Taguchi method, where Taguchi is used to design efficient and effective experiments in identifying factors that influence brick quality, such as brick compressive strength, as well as to determine optimal settings of production parameters with the aim of maximizing brick quality. The results of this research show that the factors that have a significant influence are factors A (Clay) and D (Laban Tree Ash). The high SNR ANOVA value shows this. The optimal concentration settings are 1.40 kg of Clay, 45 ml of Water, 13 grams of Palm Ash and 14 grams of Laban Tree Ash. Where with the composition design, a compressive strength value of 9.73 MPa is obtained. The compressive strength obtained increased by 6.03 Mpa from the company's standard composition of 3.70 Mpa.

Abstract: Hot mix asphalt consists of a mixture of coarse aggregate and fine aggregate with asphalt binder that has certain requirements and is heated to a certain temperature. In the process of delivering hot mix asphalt, there is a temperature drop of hot mix asphalt when it arrives at the overlay site. The purpose of this study was to determine the characteristics of the temperature drop on hot mix asphalt during the trip to the overlay site. The research method is experimental method will be used on a hot mix asphalt transport truck. The temperature measurement was carried out 5 minutes after the asphalt was poured into the truck and while on the way to the overlay site with a measurement time span of 0, 30, 60, 90 and 120 minutes. The results of the study showed that a very significant drop in the temperature of hot mix asphalt occurred in transport trucks 2 at points T4 and T6, namely the initial temperature of each 150°C to the final temperature of 139°C. The transport of truck 1 the temperature drop of hot mix asphalt that occurs is 10 °C the largest and on transport truck 2 the maximum temperature decrease for hot mix asphalt that occurs is 11 °C. Before shipping the hot mix asphalt, the weather should be considered in order to minimize temperature drop of hot mix asphalt that occurs.

Abstract: The construction of the dam project poses a significant risk of workplace accidents, particularly due to the inherent dangers associated with large-scale construction. One such incident occurred at the Karaloe Dam site in South Sulawesi in 2019, resulting in the tragic death of a heavy equipment operator who fell from a height of 85 meters along with his machinery. This study aims to identify hazards and conduct a risk assessment of workplace accidents affecting construction, workers, communities, and the environment in the Main Dam Works of the Rukoh Dam Construction Project, Pidie Regency. The determination of hazards is qualitative, employing a case study approach through direct field observation. The Identification of Hazards Risk Assessment Determination of Risk Control and Opportunities (IBPRP) method is used, along with the determination of risk levels based on the risk matrix outlined in Minister of PUPR Regulation Number 10 of 2021. The analysis yielded 23 potential hazards, comprising 14 moderate-risk categories and 9 high-risk categories. However, following control measures such as engineering solutions, administrative protocols, and the utilization of personal protective equipment, the overall potential hazards have been mitigated to a low-risk level. The potential hazard with the highest risk level at the worksite is exposure to tire blowouts from heavy vehicles, specifically dump trucks.Keywords: Project Main Dam, Hazard Identification, Risk Assessment, Risk Level

Abstract: Rukoh Dam is one of the structures that can increase the reliability of providing raw water for various purposes. The dam is expected to be able to accommodate excess water during the rainy season and anticipate water shortages during the dry season. The Rukoh dam is located in the flow of the Rukoh crew which will be assisted by the directional channels from the Inong Tiro crew dam to provide sufficient water drainage. This research aims to identify work items based on functions to ensure that the application of Value Engineering (Value Engineering) can or can not be carried out on the Rukoh Dam Irrigation Tunnel Construction Project Pidie Regency. The function analysis stage is the most important stage in value engineering because function analysis is what differentiates value engineering from other cost saving techniques. The process carried out is to identify work items through functional analysis based on their function in comparison of cost with value. From the Pareto analysis and graph, there are two high-cost work items, namely the Kr Inong supply and tunnel work. However, the cost-savings review was carried out only on suppletion duct work. At this stage of function analysis, it is known that the carrier channel structure work produces C/W ˃ 2.59, which means that it is indicated that there are unnecessary costs so that it can be continued to the next stage.

Abstract: Project success is the primary goal of every construction project execution. The achievement of project success is influenced by who and how it is managed. Therefore, the leadership of the project manager significantly determines the quality of the construction project execution. Success is generally associated with the triple constraint criteria of being time, budget, and quality. Previous research states that the consequences arising from the application of an inappropriate leadership style can affects the performance of employees and will have an impact on smooth running construction project. So the aim of this research is to analyze the relationship and influence of the project manager's leadership style on the success of construction projects. The research involved employees from a large contractor company in Aceh. Data was collected through questionnaire distribution and analyzed using correlation methods with SPSS software. From the results of data analysis using product moment correlation, it was found that the leadership style variable as a whole has a significant relationship to the success of construction projects (Sig. < 0,05). The close relationship between the two is included in the moderate category, with a Pearson correlation value of 0,512.

Abstract: Kuala Ceurape Beach is located in the Jangka District of Bireun Regency, on the Malacca Strait. This beach is renowned for its powerful waves and tides, but it is also susceptible to changes in coastal morphology, which can result in erosion and sedimentation. From 2006 to 2019, the estuary of the Kuala Ceurape coastline experienced sedimentation, leading to its closure. This issue could potentially disrupt the activities of local fishermen who rely on the estuary. To address this problem, the Aceh government proposed a plan to open the estuary channel while optimizing coastal morphology. A numerical modeling study using Delft3d application and spatial analysis study is being conducted to determine the impact of the jetty development plan on the estuary. Two scenarios are being considered: the first involves opening the estuary without building a jetty, while the second involves building a jetty. The numerical modeling considers four cardinal directions and uses input data such as bathymetry, tides, and waves. Spatial analysis is carried out using ArcGIS. Simulation results show that without the jetty building plan, sediment accumulation near the mouth of the estuary leads to its closure and a coastline progress of around ±127.583 m. However, with the jetty building plan, sediment accumulation is relatively smaller at the mouth of the estuary, and shipping is not hindered. Sediments are dominant to the right of the jetty in both scenarios, and there is still some erosion. Nevertheless, the plan to open the estuary channel with the jetty building will benefit local fishermen and increase the river's ability to drain water into the sea.

Abstract: Floods that occur in Pasie Mesjid Village, Meurebo District, West Aceh Regency are increasing every year. This research was conducted to determine the risk factors that cause flooding and priority weights in an effort to minimize flood risk using the Likert Scale and AHP (Analytical Hierarchy Process) methods. The results of research using the Likert scale method show the perception of the people of Pasi Mesjid Village who live in the riverbank area that they need to relocate. The results of public perception became recommendations for 3 expert teams on Water Resources (SDA) PUPR, BPBD (Regional Disaster Management Agency) and the Expert Team from the Faculty of Engineering, Department of Civil Engineering, Teuku Umar University), by determining the priority weight for overcoming flood problems using the AHP method. Based on the research results, the analysis of the two methods shows that relocation is the most important thing in flood management efforts in Pasie Mesjid Village
