Abstract

Damage to the roof frame construction can have an impact on other components, for example if the roof frame sags resulting in the roof covering becoming loose resulting in a leak, the leak can impact the ceiling, causing moldy damage to the worst case, collapsing. So it is necessary to ensure that the roof frame construction is always in a reliable condition, so that it does not endanger the building occupants. The method used in this research is a case study method, a model of the damaged steel roof frame construction will be made, Then a visual inspection will be carried out until further inspection. Based on the results of a visual inspection of the truss frame construction, it was found that there was a deflection in the lower frame of 4mm, there was rust which reduced the thickness of the elbow profile by 0.51mm, and the loss of some of the bolt connections was 20bh. The results of the inspection were then carried out with a strength analysis, it was found that based on the deflection results it was still below 9.33 mm, it was still safe, based on rust damage, a strength reduction of 13.31% was obtained, while based on the loss of some of the bolted connections, a strength reduction of 23.81% was obtained. Then a direct loading test was carried out on the construction of the truss frame after it had been conditioned to experience damage, capable of withstanding a maximum point load of 249 kg, where the test results experienced a decrease in strength from the plan and were still greater than the inspection results. So it can be concluded that the method for checking the construction condition of steel truss frames for deflection, rust conditions and joints can be used as a guide because the results are close to the actual conditions. The intensity of damage that occurred in the truss frame construction was categorized as light damage, because the decrease in strength that occurred was 23.81% smaller than 35%.

Abstract

The vulnerability to earthquake hazards in Semarang City is still quite low. Many people have houses that are not yet standardized to the Indonesian National Standards (SNI). Mijen District, Semarang City, is one of the districts that is quite prone to earthquake hazards because of its location close to the source of the Kaligarang fault. Therefore, it is necessary to provide preventive measures and measures for community housing buildings. The house is an earthquake-resistant building and is able to withstand sudden ground movements. By building houses that comply with Indonesian National Standards, it is hoped that damage to the building will be minimized and there will be no loss of life. By using light building materials and strong adhesive between joints, it will increase the ability to withstand seismic loads in a building. In wall construction, you can apply light bricks with polyurethane adhesive because the load caused is relatively light. Apart from being able to strengthen the bond between each layer of brick properly, this adhesive is easy to apply. It is hoped that this adhesive material will be capable of gluing and creating a strong bond in the lightweight brick layers. Varying polyurethane volume is needed to determine the effective and efficient quantity of polyurethane to produce a strong bond. For this reason, "Using Polyurethane with Varying Volumes to Strengthen the Structure of Light Brick Walls of Residents' Houses in Mijen District, Semarang City" is very important as a community service step in presenting innovations that are easy to implement independently by residents in earthquake-prone areas.

Abstract

The problem of soft clay soil is currently one of the most worrying soil problems due to the increasing use of soft soil areas for construction needs. The main problem with soft clay soil is its nature which easily absorbs water but is difficult to release the water. The large amount of soft soil in the coastal area of Semarang City implies that in the construction process in the area, it is necessary to consider consolidation reduction. Soft clay soil takes a long time to reach 90% consolidation. This is because the permeability of soft clay soil is very small so that the process of dissipating water out is quite long. This dissipation process can be accelerated using engineering techniques, one of which is preloading. This process will further accelerate the consolidation process. This study was conducted to obtain the optimization of the embankment area against land subsidence on the coast of Semarang City using the numerical analysis method. From the research results, various variations were obtained for the area of embankment for a soil depth of 20 meters with a size of 30 x 30, the decline that occurred was 1.37 cm, a size of 40 x 40, the decline that occurred was 1.552 cm, a size of 50 x 50, the decline that occurred was 1.772 cm. While for the sea decline according to Steinbener

Abstract

This research aims to analyze the influence of intrinsic motivation and extrinsic motivation on the performance of teachers with organizational commitment as a mediating variable in elementary school teachers in the Korsatpen environment, Gayamsari District, Semarang City, Central Java. The background to this research is the decline in teacher performance identified from observations from 2020 to 2024, which is influenced by various internal factors such as administrative pressure and lack of innovation factors, as well as external factors. External factors such as the impact of the COVID-19 pandemic and the lack of supervisory support. This research uses Maslow's motivation theory as a theoretical basis, and examines the role of intrinsic (encouragement from within) and extrinsic (external incentives) motivation in improving teacher performance. Organizational commitment is examined as a mediating variable that can strengthen the influence of motivation on performance. The results of the research contribute to identifying strategies for improving teacher performance through strengthening motivation and organizational commitment, thereby impacting on better quality of education in the research environment, especially in the Korsatpen Environment, Gayamsari District, Semarang City, Central Java.
