Abstract

Rehabilitation of buildings around the area around the river is considered by the owner of the activity because during high rainfall it will cause flooding. Flooding will result in delays in the building rehabilitation process because river water overflows into the activity location. One of the areas around a river in Bali, namely Tukad Bangin located in Pecatu Badung, is an ephemeral river, namely a river whose water only exists during the rainy season and often floods due to abnormal drainage channels and the absence of retaining walls. In the environment around Tukad Bangin there are buildings which during the rainy season cause frequent flooding, so a plan for building rehabilitation is carried out by making drainage channels and senders, then the results of calculating the design flood discharge in the Tukad Bangin Pecatu Badung area are carried out. The method used in this study is a quantitative method, namely measuring from direct observation at Tukad Bangin and then calculating the design flood discharge for various return periods for planning the design of drainage channels and shores. The results of the design flood discharge analysis with Q1 year are 15.47 m3/sec, Q2 year is 49.74 m3/sec and Q5 year is 65.89 m3/sec. From the simulation results of the water surface profile, the extreme depth values for discharge at 2-year return period are 1.54 m, 5-year return periods are 1.80 m, 10-year return periods are 1.93 m, 25-year return periods are 2.06 m and a 50-year return period of 2.04 m, so that with the HEC-RAS modeling it can control the height of the flood protection embankment and the design of the planned drainage channels and canals can be carried out.

Abstract

Implementation of a construction project has a series of activities or jobs that are complex and interdependent on one another. Construction project development is carried out in several stages of work, one of which is making a work schedule. Work schedules are made to make it easier for each activity to be carried out sequentially and on time. In the implementation of the Parking Lot Construction Project at Bangli Medika Canti Hospital, there was a delay in weekly progress. To anticipate changes in implementation time, an acceleration of implementation time is carried out using the method of adding overtime hours. In this research, acceleration of implementation time was carried out using the method of adding overtime hours based on Microsoft Project. The data used in this study are in the form of a planned time schedule, realization time schedule, and weekly reports. The analysis was carried out to obtain the results of activities that can be accelerated and the project implementation time after being accelerated using the method of adding overtime hours. From the results of the analysis of the Microsoft Project, there are activities that can be accelerated, namely as many as 23 work items. After analyzing with the method of adding overtime hours on the implementation of the Parking Lot Development Project at Bangli Medika Canti Hospital, the project time was 122 days. This time is the same time at the initial planning. In the process of implementing the project, there was a delay in progress which resulted in a postponement of the project plan schedule to 129 days.

Abstract

Tukad Kelandis is a tributary of the Tukad Ayung Watershed which is located downstream. In 2021 floods occurred in Tukad Kelandis resulting in one of the places affected by flooding, namely the Art Center area. So it is necessary to do research on the analysis of peak flood discharge on the Tukad Kelandis river using rational methods. Maximum runoff occurs when the rainfall is during the same time as the catchment area concentration time in the rational method. Based on the research results, the amount of planned flood discharge in the Tukad Kelandis watershed was obtained using the rational method for return periods of 2, 5, 10, 20, and 25 years, namely: Q2 Year = 273,890 m3/s, Q5 Year = 337,372 m3/s, Q10 Year = 373,194 m3/ s, Q20 Year = 399,610 m3/ s, Q25 Year = 413,406 m3/ s.

Abstract

Water as the basis of life is very important for human life. Population growth is increasing the need for potable water in communities, especially in southern Badung County. The source of drinking water demand is managed by PDAM Tirta Mangutama Badung Regency. The problem is that in the two districts, all the communities that are not part of the PDAM do not have drinking water. Considering this, it is necessary to identify the needs of people who need water in the community, to have clean water and sanitation facilities for houses and hotels in Kuta and South Kuta in the next five years. of the lake estuary IPA. This study was conducted by evaluating the water treatment process to obtain clean water, analyzing the clean water requirements and analyzing the operating costs for the treatment of clean water. The analysis shows that household and hotel water needs will increase by ±10% by 2025. The clean water capacity of the Estuary DAM IPA is 500 liters/second, which is still sufficient for the needs drinking water for homes and hotels in Kuta. South Kuta District. Water treatment operating cost requirements (chemical costs and power plant costs) increased by ±7% by 2025

Abstract

The foundation has an important role to transfer the structural load above it to the lower soil layer. To prove the accuracy of the calculation of the design of the carrying capacity of foundation piles in the field, it is necessary to carry out a test. The Tsinghua Campus Project is a project located in the Serangan area using a bore pile foundation with a diameter of 80 cm where to determine the carrying capacity of the foundation pile used Static Loading Test (SLT) and Pile Driving Analyzer (PDA) test methods. The purpose of this study is to determine the choice from the results of the comparison of implementation methods with the time and cost required in the two test methods.  The method used in this study is through observation that visits directly to the field to look for aspects that need to be discussed to compare the two testing methods. The results of the Static Loding Test require a fee of Rp. 257,990,000.00 for testing 1 point of foundation piles and a test duration of 7 days for 1 test point, while the Pile Driving Analyzer requires more complex and more advanced reality models so that the results can be used in motion analysis. Then it is necessary to get a better way to separate the resistance of the shaft and the foot. However, please be aware that those using PDA results should understand that it is important to include information about subsoil and soil characteristics, groundwater and pore pressure, and other geotechnical matters and bring this information equivalent in quality to dynamic records. In addition to requiring a cost of Rp. 23,104,000.00 and the duration of the Pile Driving Analyzer test is for 2 days for 2 test points. The ultimate carrying capacity value of the Pile Driving Analyzer analyzer is known to be closest to the results of the Static Loding Test test interpreted by the Chin method

Abstract

Drainage is a system created to overcome the problem of excess water above ground and water below ground. The performance of the drainage system is determined by using good construction techniques, carrying out routine and periodic maintenance. Heavy rains not only cause surface water runoff but also urban surface water runoff which forms puddles of water due to the low carrying capacity of the drainage system. One of the areas that experienced flooding in the city of Denpasar was Jalan Antasura in the Peguyangan Kaja area, North Denpasar, which was caused by blockage of channels by sediment caused by rubbish. This research monitors and evaluates rainfall, flood discharge and water capacity in drainage channels. The results of the calculation evaluation and comparison with HEC-RAS modeling show that the water capacity in the drainage channel at the 0-800 m point does not meet the design flood discharge results for all return periods, so it is predicted that the drainage channel will cause flooding, while the water capacity in the drainage channel at the point 800-1000 m still meets the design flood discharge at the 2 year and 5 year return periods, but does not meet the 10 year return period, so it is predicted that the drainage channel will still meet capacity if channel normalization is carried out every year.
