Abstract

The word of construction is no stranger to rework. In the course of the implementation of construction, rework work may occur which can cause delays in the work process and swelling of the project cost budget. This can be influenced by several problems or factors that are often encountered during development work such as human resourse factors, documentation and disign, managerial with this can be from sevaral that have been mentioned that must be considered when planning construction development. In this study using descriptive research that directly takes data in the field by means of interviews, documentation, observation in order to be able to answer the research objectives properly and correctly according to the data obtained from the aforementioned data collection process. So that it can be seen the most frequently encountered rework jobs in the field. Based on the results of the study, it was shown that the dominant factor causing rework was managerial factor. The type of work that often experiences rework work is the finishing work of the second floor column casting. With the details of the causes of rework, the results obtained are design and documentation 22.5%, managerial 40.4%, and human resources 37.2%. The process of rework in the construction of the R S Roemani Semarang building can be concluded that there are several problems or identification of rework, namely porous columns, column slopes and column centring.

Abstract

Accessibility related to public transport is a means of advancing the economic welfare of the community, creating and increasing economic degrees, as well as a precursor sector of other sectors. Therefore, people with disabilities are also entitled to the same service to the public transportation as an effort to realize similarities, the equality of citizens and the enhancement of the role of disability. This research aims to analyse disability access and the role of the transportation service of Semarang and PT. Trans Semarang on Bus Rapid Transit in Semarang City. This research uses a type of qualitative approach that is implemented through interviews, observations and documentation. The conclusion of this research shows that from the regulatory aspects, the government of Semarang should be appreciated because the government of Semarang has tried to fulfill the rights of the disabled. But from the implementation aspect, there needs to be an improvement because the accessibility of disabled people running optimally can be seen through the condition of public facilities in the city of Semarang. Public facilities in the city of Semarang do not completely ignore the reference accessibility means there are public facilities that have been good enough but many more are not optimal.

Abstract

Hospitals are health care institutions that provide a full range of individual health services and provide inpatient, outpatient and emergency services. The comprehensive health services referred to in this case include promotive, preventive, curative and rehabilitative.[1] The construction of the new building at PKU Muhammadiyah Blora Hospital will be the center of the physiotherapy clinic, pharmaceutical satellite, commercial area, drop off, ICU, inpatient, office. The existence of the new building is a step to improve the quality of health services for patients. The new hospital building is located to the east of the main building in the PKU Muhammadiyah Blora Hospital complex. The work observed is the work of beams and reinforced concrete floor slabs. This work has several steps of workmanship. The work on the beams and floor slabs must complete the reinforcement and formwork simultaneously first, then the casting can be done.

Abstract

Abstract. Construction projects often face challenges in maintaining quality, one of which is structural defects that can affect the quality and safety of the building. This study aims to analyze the level of defects in column, beam, and slab structures using the Six Sigma DMAIC method and provide solutions to improve these defects. The study was conducted on the Emirates Indonesia Cardiology Hospital Building Construction Project in Surakarta. The method used is a quantitative descriptive approach with the stages of Define, Measure, Analyze, Improve, and Control. Data were obtained through field observations, interviews, documentation, and secondary project data. The analysis results show that the average sigma level value is above 3, with the highest level in the column structure reaching 4.3 sigma for the type of concrete flow defect. The main causes of defects come from human factors, work methods, materials, and supervision. Improvement solutions are formulated using a fishbone diagram analysis approach and the assistance of NVIVO software for qualitative data analysis. This study shows that the Six Sigma DMAIC method is effective in identifying and reducing defects in concrete structure work and can be used as a quality control strategy in construction projects.Keywords: Six Sigma, DMAIC, Structural Defects, Construction Quality, NVIVO

Abstract

Proyek konstruksi bangunan gedung memiliki kompleksitas tinggi yang sering memicu permasalahan kinerja, seperti keterlambatan, penurunan kualitas, dan rendahnya produktivitas tenaga kerja. Kondisi ini menegaskan bahwa keberhasilan proyek tidak hanya bergantung pada aspek teknis, tetapi juga pada efektivitas pengelolaan sumber daya manusia (SDM). Penelitian ini mengkaji pengaruh kompetensi, motivasi, dan disiplin kerja terhadap kinerja SDM menggunakan pendekatan kuantitatif dengan analisis SEM-PLS berbasis data kuesioner. Hasil penelitian menunjukkan bahwa ketiga variabel tersebut berpengaruh positif dan signifikan, dengan kompetensi sebagai faktor paling dominan. Temuan ini mengindikasikan bahwa peningkatan kinerja tenaga kerja konstruksi memerlukan pengelolaan SDM yang terintegrasi melalui penguatan kompetensi, peningkatan motivasi, dan penerapan disiplin kerja secara konsisten.

Abstract

Abstract. Land preparation is a crucial initial stage in construction work to adjust the site’s topography to the planned elevation. One of the main activities in this phase is earthwork, specifically the cut and fill process. This study compares the conventional method and the Building Information Modeling (BIM) method in calculating earthwork volumes for the Cut Fill Project at KIT Batang, Block A Lots 9, 10, 11, 12, and 12A. The conventional method uses AutoCAD, Civil 3D, and Microsoft Excel with the Average End Area method, while the BIM method applies an integrated 3D digital model in Civil 3D through the Compute Materials and Volumes Dashboard commands. The results show that the conventional method produced excavation (cut) and embankment (fill) volumes of 5,715.65 m³ and 111,196.22 m³, respectively. Meanwhile, the BIM method generated 5,894.19 m³ (cut) and 112,093.61 m³ (fill) using Compute Materials, and 5,665.10 m³ (cut) and 112,038.57 m³ (fill) using Volumes Dashboard. The deviation of BIM results compared to the conventional method was less than 5%, with +3.12% and +0.81% for Compute Materials, and –0.88% and +0.76% for Volumes Dashboard. These small deviations indicate that the BIM method provides higher accuracy and efficiency, as it automatically calculates volumes based on an integrated digital surface model, reducing potential human error.Keywords: Cut and Fill, Earthwork, Conventional Method, Building Information Modeling (BIM), Civil 3D
