Abstract

This study discusses the comparison of cost and time efficiency between precast and conventional concrete systems in the structural work of building construction. The research adopts a quantitative comparative approach on two segments of the Sartikaasih Bhayangkara Hospital project in Bandung. The BoQ calculation results show that the precast system incurred lower total costs, amounting to IDR 17.6 billion (A1) and IDR 12.74 billion (A2), compared to the conventional system with IDR 19.86 billion (A1) and IDR 14.29 billion (A2). In terms of time, the precast system demonstrated significant efficiency, with savings of 65.02% on A1 and 21.43% on (A2). This efficiency contributes to the reduction of indirect costs and the risk of project delays. These findings indicate that the precast system can serve as a more economical and efficient alternative for building construction projects.

Abstract

The selection of structural materials plays a crucial role in determining cost efficiency and construction time in building construction projects. This study aims to analyze and compare the construction costs of reinforced concrete and steel structures in the construction of the Modern Islamic Boarding School An-Nizam in Purwokerto. A quantitative comparative method was used by calculating the volume of work, construction cost estimates (RAB), and project duration for both types of structures. The analysis focused on main structural elements such as columns and beams, based on detailed drawings, unit price standards, and project technical data. Based on the calculations and analysis of this project, it can be concluded that the total construction cost for the reinforced concrete structure is Rp 8,983,363,148.58. Meanwhile, the total construction cost for the steel structure is Rp 8,445,489,989.60. The duration of the steel construction work is 19-20 weeks, and the duration of the concrete structure construction work is 25-30 weeks. Therefore, it can be concluded that from this case study, the total cost required for concrete structure construction is cheaper than steel structure construction by a difference of Rp 537,873,158.98. However, the duration of steel structure construction is faster than concrete construction, with a difference of 6-10 weeks.

Abstract

The use of Darma Waduk is as a source of clean water and a place of fish cultivation in the form of net cages. The number of floating net cages that currently exist is 6521, and the number continues to increase quite significantly from the previous year. The existence of floating net cages affects water quality, while water quality is an aspect to be considered in water utilization. The study aims to analyze the impact of floating net cages on water quality and efforts to control the floating net cage population in Darma Waduk. The research uses a quantitative and qualitative approach, starting with surveys and interviews with floating net cage farmers and related services. Subsequently, water samples were taken, and the results of laboratory tests were analyzed using the Pollution Index (IP) method. The results of the calculation using the pollution index (IP) method at the first point (PDAM Intake Area) obtained a result of 4.14, at the second point (around the floating net cage area of the village of Cipasung) a value of 3.76, and at the third point (in the floating net cage village of Jagara) a score of 4.12. The results of the research showed that the water quality taken from the three points of the sample included light pollution when referring to the class I water quality standard according to PP No. 22 for 2021. However, the presence of household and agricultural waste also contributes to the pollution burden in the Darma Valley.

Abstract

  The effect of on street parking in urban commercial areas can cause a degradation of road performance. Therefore, the development of an integrated parking system is crucial to be carried out in commercial areas so that the performance of road sections does not degrade and does not cause heavy congestion. This study aims to provide recommendations for integrated parking locations based on existing parking conditions in the study area, so that they can be integrated and combined in one location. The method used is a primary survey that refers to the guidelines of the Indonesian Road Capacity Manual (IRCM) 1997 in analyzing traffic performance, and refer to the Guidelines for the Implementation of Parking Facilities 1997 in analyzing parking conditions. Meanwhile, for recommendations in determining alternative parking locations using SWOT analysis. The result of this research is the proposed location for integrated parking at Pasar Balong with the recommendation of a 4-floor building. The SWOT analysis showed that its strengths are its strategic location and high parking demand, its weaknesses are land limitations and lack of integrated parking management, its opportunities are potential for revenue and increased traffic flow, and its threats are resistance from local businesses and significant investment needs. The implication of this study is to provide a solution to the problem of roadside parking in commercial areas that interfere with traffic flow, improve the efficiency and accessibility of parking facilities for the community, and become a reference for further research on integrated parking management in other commercial areas.

Abstract

Problems that often arise in the city of Cirebon are flooding caused by rain, land changes not supported by adequate infrastructure, narrowing of drainage channels and sedimentation of channels. This is the location where flooding often occurs in the Pemuda Street area and its surroundings. Therefore, it is necessary to carry out research on surface flow analysis as an effort to handle floods with the aim of inundation management strategies to reduce excessive rainwater runoff in drainage areas and channels. The research methods used were problem identification, literature study, data collection, analysis and design planning. The results can show that inundation is handled in two ways, first by changing the dimensions of the channel at the initial height H to 0.45m, it still experiences inundation, this is due to the difference in elevation which causes inundation in the channel. There was a change in the flood inundation area to 23,127 ha from the original 58,958 ha, meaning that the flood free area increased from 9,388 ha to 35,831 ha. The second way is by making 378 infiltration wells spread across 34 channels that experience flooding. With these infiltration wells, the flooding can be reduced to a minimum from an area of ​​23,127 ha to 0.040 ha. The success rate for flood management efforts reached 99.908%, with failure being 0.092%. Of the area of ​​68,346 ha, the flood-free area reached 68,306 ha and the remaining inundated area was 0.040 ha..
