Water runoff is temporarily stored in retention ponds as part of a flood control scheme to avoid major floods. There are currently a number of retention ponds in Palembang City that work to reduce flooding during rainy seasons. Land use is expanding, and water catchment areas are getting smaller as a result. The feasibility of constructing a retention pond in Palembang City's Sukarami District is discussed in this study. The usability, hydrology, and physical environmental aspects of data analysis are the main areas of study. The study of hydrological aspects indicates that the planned retention pond has an area of 6.55 Ha and is capable of accommodating a large water discharge of 0.294 - 0.466 m3/sec for a return period of 50 years. The research also demonstrates the benefits of collecting rainwater runoff and improving environmental aesthetics. The construction process and the presence of this retention pond will have an impact on environmental quality, according to the findings of the study of physical environmental elements.

The Gandus Camping Ground Access Road Construction Project is required to be completed on time so that consumer confidence is maintained. To achieve this, control is needed which must be known in advance through ongoing project performance. One way to determine project performance is the Earned Value method which integrates aspects of cost, time and work performance. Therefore, this Earned Value analysis is applied to the Gandus Campground Access Road Construction Project. Project performance is analyzed based on cost performance index (Cost Performance Index) and time (Schedule Performance Index). Calculations are based on planned value, earned value and actual costs. Performance control is reviewed for 8 weeks, namely week 12 to week 19. The results of the analysis in weeks 12 to 19 show that the costs incurred were greater than planned and the implementation time was longer than planned as indicated by the average value of CPI = 0.976 (CPI <1) and the average value of SPI = 0.999 (<1). The results of the estimated final project cost are IDR 3,740,377,358.49 with an implementation time of 24 weeks, which means the project will be in accordance with plan.

A feeder system is a transportation system that aims to serve parts of the city that are beyond the reach of the main modes of transportation. The feeder system is designed to be used in residential areas towards the main road corridor so as to create a better hierarchy of public transportation systems between the main mode, branch mode, feeder mode. With the holding of this feeder, one of them is a milestone to increase LRT (Light Rail Transit) occupancy. The purpose of this research is to find out how effective and efficient feeder public transportation is and to find out the characteristics of passengers using feeder services on corridor 5, the analysis method used in this study uses a mixed method between descriptive and quantitative. Based on the results of the analysis that has been done, it is known that the background of different passengers at each observation point and the results of the feeder performance with a vehicle density value of 0.322 vehicles / hour, waiting time of 6 minutes, vehicle frequency of 4 - 5 vehicles / km, speed of 17 km / hour, travel time of 0.8 hours, operational capacity of 11.4%, headway 12 minutes, load factor 96% and utility 230 km in one day of operation.

Palembang city has an area of 400.61 Km2 and is divided into 19 sub-watersheds that flow into the Musi river. One of the sub-watersheds in Palembang city is Buah Sub-watershed with an area of 10.79 Km2.The study area is located at Sapta Marga Street, Kelurahan Bukit Sangkal, Kecamatan Kalidoni, Palembang City.The purpose of this study was to determine the condition of the existing secondary drainage channel on Sapta Marga road, determine the peak discharge in the Buah Sub Watershed, make new drainage dimension planning for the study area and simulate new drainage after recalculating the dimensions with the EPA SWMM 5.1 program. Primary data in this study are the dimensions and length of existing channels, channel slope data taken using theodolite tools. Secondary data is rainfall data from the BMKG station for 5 years and land use data. Peak discharge is calculated by the Rational method. The results of this study obtained the condition of the existing secondary drainage channel on Jalan Sapta Marga, with channel dimensions of 0.3 m x 0.3 m with a square cross section, runoff occurs at STA 1045 - STA 1195. The peak discharge (Qh) in Sub Watershed Buah, with an area of 77.45 ha River Drainage Area (DPS) is 0.20 m3 /s. Planning new secondary drainage dimensions to be able to accommodate peak discharge in the study area with new dimensions of width (B) 0.65 m, height (h) 0.65 m, and freeboard (f) 0.45 m. The results of the new drainage simulation using the EPA SWMM 5.1 program secondary channels do not runoff.

STUDI LITERATURE REVIEW PERKEMBANGAN PENELITIAN ASPAL PORUS (TAHUN 2017 – 2021)

Wed, 19 Jun 2024 00:00:00 +0000

Road pavement is composed of layers that are hardened with a mixture of aggregate and asphalt (flexible pavement) or aggregate and cement (rigid pavement). Each of these types of pavement has a different behavior. Environmental factors such as high rainfall can influence pavement performance where flexible pavement is very susceptible to waterlogging, therefore there is a type of porous asphalt called porous asphalt. This article discusses the results of a literature review of the development of existing porous asphalt from 2017 to 2021 using an international journal database. The results of the literature review show that there are several modifications to the porous asphalt mixture, namely by using rubber materials, polymer materials, fiber materials, and filler materials. Each of these materials produces a different performance. For this reason, further research is needed regarding the use of rubber and fiber materials in modifying porous asphalt mixtures to complete information regarding the development of porous asphalt.

One of the issues in road infrastructure is traffic congestion, which leads to longer travel times for road users. Traffic congestion is a serious problem in big cities like Palembang, including around Monpera, a tourist attraction located near the city center surrounded by busy roads. Traffic involves variables such as volume, speed, and density with random variations. Therefore, it is important to study the impact of Monpera's tourism activities on traffic. The research methodology used includes surveys and observations to gather data on visitor numbers, air quality testing, and traffic volume during peak hours. The research findings indicate that the impact observed is an increase in traffic volume, especially on weekends from 8:00 AM to 12:00 PM. Based on air quality measurements around Monpera, it still meets the established environmental standards. This suggests that Monpera's activities do not have significant effects on air quality. However, the level of traffic service in this area is rated low at 0.77 indicating that traffic flow tends to be unstable
