Abstract

The implementation of construction work, there are still many problems, namely schedule mismatches, delays, and cost calculations that are sometimes inaccurate because they still use conventional methods. In the Al-Multazam Islamic Boarding School Building Construction project, Kuningan still uses traditional methods, where this method has the potential for human error because in making calculations it can be wrong to enter data which will ultimately change the calculation results to be greater. This research aims to show that the BIM method is very important to be applied in construction projects to streamline work productivity in building construction projects. In this case, there are differences in the results of the calculation of Quantity Take Off on the project, the difference in the results of the analysis shows that there is a difference between the existing volume and the volume of the Quantity Take Off results using the BIM concept, Foot plate foundation work has an average difference of 6.67%, Tie Beam has a difference of 7.62%, Beams have a difference of 5.30%, Columns have a difference of 8.26%, and Floor Plates have an average difference of 2.51%.  This research has implications for the application of BIM to enable a more structured, efficient, and accurate planning and implementation process, thereby reducing the potential for errors caused by human factors. In addition, the use of BIM can also increase efficiency in overall project management, including in schedule monitoring, cost estimation, and resource management, which in turn can increase work productivity on building construction projects.

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..

Abstract

Pedestrian path conditions are one of the factors that affect willingness to walk and play an important role in supporting historical tourism activities. This study analyzes the performance of pedestrian paths expressed by Pedestrian Level of Service (PLOS) in the colonial historical area of Kota Lama Cirebon.  The method used in this study was to conduct a geometric survey of pedestrian paths, pedestrian flow surveys, and pedestrian travel time surveys in 10 segments scattered throughout the study area. The survey results were analyzed regarding the 1985 Highway Capacity Manual (HCM) and PLOS values generated based on available walking space. The study shows that in terms of walking space availability, most of the segments in the study area have a PLOS A score, which means they are performing well. In comparison, some segments have poor PLOS, such as Merdeka Street, Yos Sudarso Street, TJ Street, and Kebumen Street, due to the unavailability of sufficient walking paths to serve pedestrians or the presence of side obstacles that reduce the effective width of the pedestrian path. To overcome these problems, several things need to be done, such as: 1) issue a policy prohibiting selling on pedestrian paths to reduce side obstacles so that the effective width of the pedestrian path can increase; 2) widen the pedestrian path at least according to the applicable standards; and 3) provide pedestrian paths on segments that do not yet have pedestrian paths.

Abstract

Rainy season flooding: Ujung Jaya Regency experiences flooding almost every year, this annual flood phenomenon causes material losses. The research aims to analyze the capacity of the Cipelang River which is located in Sumedang Regency. The Cipelang River is part of the Cimanuk Watershed (DAS) with an area of ​​around 130.70 km², which has several tributaries such as Ciandana, Cicacaban, and Cipanassaat. The methods used in this research include collecting hydrological data, topographic analysis, and evaluating land use around the river. Rainfall and river flow data were taken from the nearest meteorological station to determine water storage potential. Results of analysis of existing river storage capacity and flood discharge. The maximum capacity of the Cipelang river is 409,002 m3/s. Nakayasu HSS method planned discharge using river watershed discharge occurs in the 100 year anniversary period. However, time periods of 2,5,10,25,50 years are considered safe. The results of comparing the planned discharge of the Hasper method with the discharge of the river catchment did not occur. So the most suitable method to use is the hasper method, land use which is dominated by irrigated rice fields and gardens also contributes to water management in this watershed. It is hoped that this research can provide recommendations for better water resource management and flood risk mitigation in the area. These findings are important to support sustainable infrastructure development and maintain ecosystem balance in the Sumedang Regency area.  Keywords: Rain , River, Discharge, Capacity, Flood
