Abstract

Semarang as a city located in the coastal area is dealing with the some problems, such as rising sea level, land subsidence, scarcity of land and illegal settlers. In order to deal with rising sea level, a polder system is developed in Kemijen (northern of Semarang). This polder system depends on dredging, a pumping station and retention basins to store water. To make the polder function well and reduce the floods, the existing retention basins should be expanded. Therefore, people who are living at the borders of these basins should be relocated or floating houses could be a solution.. This study aims to determine the acceptance of the Kemijen inhabitants towards floating houses as alternative residential in coastal areas. Data collecting in this study were obtained through interviews with the Kemijen residents and stakeholders. The data  then processed by SWOT analysis. Based on the research result, it can be concluded that the social acceptance of the inhabitants is quite low, but there is potential because they see positive elements in a floating house. According to the survey most inhabitants do have insufficient income to pay for a floating house. Building on water is still not legal in Indonesia and therefore the law should probably be adjusted. Besides the land owner is still reluctant in building legal houses on its land. In order to improve the social acceptance of floating houses, these factors should be strengthening, namely relative advantages, compatibility, complexity, trialability and observability.

Abstract

Tambak Lorok in Semarang is one of the areas that often undergoes tidal floods. The construction of dam and dike infrastructure is an effort to overcome tidal floods. As one part of the flood control system, the dike has an important role. The construction projects requires an alternative selection method of dike construction in order to function optimally. This research aims to determine the order of priority criteria and alternative construction of dikes. The data were obtained through questionnaires to experts in the field of dike construction. The aspects of criteria used to analyze alternative dike construction are : functions and benefits, site conditions, costs and construction implementation.  The dike construction alternatives include a Concrete Sheet Pile (CSP), Parapet Wall with reinforced Corrugated Concrete Sheet Pile/CCSP and landfill with Geotube Components. The questionnaire were processed using the Analytical Hierarchy Process (AHP) method with the Expert Choice v.11 application. The results showed consistency ratio (CR) of 5%, which means that research data were consistent and could be accounted for. Based on weighting in pairwise comparisons, the priority criteria in selecting type of dike construction are : functions and benefits (33%), site conditions (32%), cost (18%) and construction implementation (17%) The priority alternative dike construction is reinforced Corrugated Concrete Sheet Pile/CCSP (39.7%), landfill with geotube components (3.28%) and Cylindrical Concrete Piles (CSP) (27.5%). Dike construction with reinforced CCSP is a top priority in the handling of tidal floods in the Tambak Lorok.

Abstract

This research explores risk management in construction projects to prevent potential failures due to natural factors or human errors. The objective is to develop a risk assessment model for failures in construction and building projects, focusing on identification, categorization, risk level determination, and model development. The research benefits encompass theoretical contributions to construction risk management, governmental policy guidelines, operational assistance in project risk management, and enhancements in the safety and quality of construction projects. This research innovates by expanding research variables, incorporating failure risk level assessments, and utilizing technological approaches. The research methodology combines quantitative and descriptive approaches, focusing on failure risk factors from service/contractor providers, consultants, and project owners. Data is obtained through literature studies, secondary data, and primary data via questionnaires. The analysis involves factor analysis, importance index, impact probability matrix, and the Partial Least Square (PLS) method for structural analysis. The research conclusion identifies failure risk factors including financial aspects, management, equipment availability, and natural impacts such as floods and earthquakes. The risk assessment model categorizes risks into high, medium, and low, enabling appropriate anticipatory measures. This model provides guidance for stakeholders to mitigate risks, improve quality, and maintain the integrity of construction projects and buildings, supporting safety and success throughout project stages. This research makes a significant contribution to construction project risk management and construction quality improvement.

Abstract

The construction of Universitas Muhammadiyah Semarang (Unimus) Hospital employs a self-management approach. During the construction phase, delays and a decline in building quality that did not align with the planning phase were observed. Therefore, a review of the management approach is necessary to ensure timely completion, maintained quality, and cost efficiency. This study evaluates the effectiveness of time, cost, and quality management in the construction project. The analysis method used is the interactive data analysis paradigm, involving data reduction, storage, and analysis using IBM SPSS 20. The analysis results indicate that time and cost management have been effective, with the construction work being completed within the set schedule and the costs not exceeding the Budget Plan. Quality management is rated very good with a score of 4.35, indicating that the construction process is strictly carried out according to specified materials and work procedures. Cost savings are also rated very good with a score of 3.89, indicating effective cost control. Time efficiency is rated good with a score of 4.06, showing that the project can run the schedule efficiently. Based on the research results, the researcher recommends enhancing leadership aspects and increasing active involvement of top management in supervision and strategic decision-making. This study also shows that self-management can promote transparency, efficiency, and high-quality outcomes in construction projects.
