Abstract

Abstract Geomorphologically, the city of Semarang is formed from the delta formation of the Kaligarang River, if the water discharge increases, it is certain that inundation will occur along the river. In addition, puddles caused by high tides are also common. The rapid growth of the city greatly affects the availability of supporting infrastructure such as roads. The age of pavement planning in the city of Semarang is often not reached due to the condition of the flood disaster. The purpose of this study is to determine the level of resistance of the subsurface layer to water which will affect the stability of the paving pavement. The initial stages carried out were the preparation of a research proposal containing the preparation of tools and materials, literature studies and the design of primary and secondary data collection instruments, the next stage was making laboratory test samples and conducting hydraulic test analysis to determine the optimum water content, the end of this activity stage was the formulation conclusion. Based on the results of the analysis, it was found that the water content greatly affects the depth of subsidence, the higher the water content, the higher the decrease. It was proven by testing in the lab, the water content in the base course was 10% sinking 40 mm, 20% 80 mm and 30% 120 mm. Keywords: delta areas; water content; hydraulic test; paving stability AbstrakSecara geomorfologi kota Semarang terbentuk dari formasi delta Sungai Kaligarang apabila debit air meningkat maka bisa dipastikan genangan akan terjadi di semapadan sungai tersebut.

Abstract

Floods and Rob floods are natural disasters that often occur in Indonesia. The UNISSULA campus area is in the Pantura road area. UNISSULA is one of the campuses affected by floods and robs. Extreme weather conditions and rising sea levels have exacerbated the condition of the north coast road. Thus causing traffic jams and activities of the surrounding community to falter.The purpose of this study was to analyze the drainage system of the UNISSULA campus area by utilizing the potential of a storage pond by disposing of water directly into the estuary. With this research, it is hoped that it can be used as data and material for consideration for the development of a drainage system in the campus area and to become a pilot campus to control flooding. The method used is a simulation of the rainfall-runoff model using EPA SWMM Version 5.1.This study carried out two scenarios in carrying out flood control efforts, namely the first scenario, the existing west, and east retention ponds will be connected to pond 1, for the pond in the north, will be connected from pool 4 to the engineering pool, channeled to pool 3, to pool 2 and connected with pool 1 equipped with a pump with a capacity of 1 m3/sec with additional long storage from pool 2 to pool 1 along 184 meters. The second scenario is to break the direction of the front and rear drainage flows. For drainage, it will be pulled into pond 4, then a technical pond until it is connected to pool 2 and discharged directly into the sea with a flood pump with a capacity of 0.5 m3/sec. This makes the flood travel time short and is expected to reduce inundation. With this scenario, it can also be developed as Khairu Ummah Edu-tourism Khaira Ummah in the campus area.

Abstract

Penelitian ini mengevaluasi modifikasi aspal dengan resin katalis untuk ketahanan terhadap banjir rob di Pantura Semarang-Demak, dengan pengujian perendaman selama 7, 14, dan 21 hari. Hasil menunjukkan bahwa aspal dengan resin katalis, kecuali komposisi 4%-2% dan 4%-4%, masih layak digunakan setelah 7 hari perendaman. Namun, setelah 14 dan 21 hari, semua komposisi tidak memenuhi standar teknis Bina Marga, terutama karena nilai rongga udara yang melebihi batas. Semakin lama perendaman dan semakin tinggi komposisi resin serta katalis pada Asphalt Concrete Wearing Course (AC-WC) yang terendam rob, nilai VIM meningkat, menyebabkan lebih banyak rongga dan menurunnya daya tahan. Komposisi 4% Resin dan 0% Katalis dengan perendaman 7 hari memenuhi Spesifikasi Teknis Bina Marga 2018 revisi 2. Perendaman terus-menerus juga berdampak negatif pada stabilitas, meningkatkan risiko deformasi permanen, bleeding, dan stripping. Keyword : Rob, Aspal Modifikasi, Stabilitas

Abstract

Fast track concrete is a ready-mix concrete that hardens quickly and can be used directly for traffic. This concrete has special specifications that cover the needs of road pavement segment concrete that is opened for traffic when the concrete age is less than 7 days. This study aims to determine the value of compressive strength and flexural strength of concrete with a comparison of substitution of dramix steel fiber and Polyethylene Terephlate (PET) aggregate. This study uses an experimental method with a trial of testing concrete cylinders and beams with compressive and flexural tests with four compositions of normal concrete, dramix steel fiber substitution concrete, Polyethylene Terephlate (PET) aggregate substitution concrete and concrete with a combination of dramix steel fiber and Polyethylene Terephlate (PET). The composition test was carried out on fast track concrete with a quality of fc'30 Mpa within 4 days including compressive strength and flexural strength when the test object was 4, 7, 14, 21 and 28 days old. The results of the study showed that the use of dramix substitution concrete had the best results with an average compressive strength value of 30 Mpa fast track concrete within 4 days of 29.92 Mpa and a flexural strength of 3.59 Mpa greater than the mixture of substitution concrete Polyethylene Terephlate (PET) aggregate substitution obtained an average compressive strength of 20.785 and flexural strength of 3.35 in a concrete age of 4 days and the combination of dramix substitution and Polyethylene Terephlate (PET) aggregate concrete had an average compressive strength value of 21.31 Mpa and Flexural strength of 3.41 Mpa at the age of 4 days, which later the value will continue to increase until the immersion age of 28 days.

Abstract

The primary objective of this study is to identify key variables influencing the implementation of bridge construction standards, focusing on human resources, environment, work methods, and materials. Using a quantitative approach, the study involved 130 respondents, including project managers, field engineers, supervisors, construction workers, and supervising consultants. Data were collected through validated questionnaires and analyzed using linear regression to understand the relationships between the tested variables and the implementation of bridge construction standards. The results indicate that all four factors have a significant impact, with materials being the most dominant variable (regression coefficient of 0.49, p-value < 0.05) affecting the effectiveness of standard implementation. Additionally, human resources, environment, and work methods were found to play essential roles in improving construction quality and bridge safety. Effective human resource management, proper material selection, adaptation to environmental conditions, and efficient work methods are crucial to ensure compliance with construction standards. The findings of this study can serve as a reference for developing future construction regulations and policies, although there are limitations related to the scope and variables examined. Further research with a broader scope and additional variables, such as financial and technological aspects, is highly recommended to gain a more comprehensive understanding.

Abstract

ABSTRACTHigh-quality road infrastructure is a crucial foundation for economic development and community mobility. However, many road projects often fail to meet expected standards, causing losses for both the government and the public. Previous studies have highlighted various technical and managerial weaknesses. This study offers a novel perspective by deeply examining regulatory and institutional aspects while providing practical recommendations for their improvement. A case study approach was employed, involving project managers, contractors, field supervisors, and affected community members as research participants. Data were collected through in-depth interviews, direct observation, and document analysis, followed by qualitative analysis methods. The findings reveal that the use of substandard materials, improper construction techniques, suboptimal project management, and non-compliance with regulations—exacerbated by budget constraints, poor coordination, and weak oversight—contribute to substandard project outcomes. The primary contribution of this study lies in providing actionable insights to enhance regulatory frameworks, strengthen oversight mechanisms, and build institutional capacity to ensure road infrastructure quality aligns with public and governmental expectations.Keywords: Road Project Management, Road Infrastructure Management, Road Project Regulations, Road Quality.ABSTRAKInfrastruktur jalan yang berkualitas adalah fondasi penting bagi perkembangan ekonomi dan mobilitas masyarakat.

Abstract

Risk management in the form of initial mitigation by considering internal and external factors and issues will be able to narrow the gap in making predictions and strategies to accelerate the completion time of work until it is completely completed. The Loji-Banger River Flood and Robo Control Project Package 1 is one of the government's strategic projects which aims to overcome tidal floods on the north coast of Pekalongan City. Risk assessment is carried out in several stages from risk identification to mitigation suggestions to reduce the scale of risk from inherent risk to residual risk which shows that of the 35 variables assessed, all risk factors have decreased on the risk scale, however there are several risk factors that are of particular concern. because the residual risk is still at a moderate level, so very tight controls or control are needed because it could potentially cause a gap in the work acceleration target time, including possible risks due to delays in material delivery (X2), possible risks due to some of the work land not being free (X11 ), possible risks due to the DIPA Budget Refocusing Issue, its influence on cash flow (X18), possible risks due to the influence of the company's financial condition on the project action plan (X19), possible risks due to errors in preparing work sequences or work zoning (X27).
