Abstract

The rapid development of road infrastructure increases the need for materials to be used, including the use of aggregates. This study aims to examine the use of aggregate from the Sewan River in Sarmi Regency as an asphalt mixture. In this study by conducting several tests such as checking the characteristics of course (stone), fine (sand), filler and asphalt characteristics. After that, a mixture of asphalt composition (AC-WC) was made and then the Marshall test was carried out to obtain the properties of the mixture. The results of testing the composition of the AC-WC mixture obtained the composition of the mixture for the optimum asphalt content of 7.50%, coarse aggregate 36.75%, fine aggregate 50.00%, and filler 5.75%. This shows that the aggregate characteristics of the Sewan river for the AC-WC mixture with the conventional Marshall method that meet the 2018 General Specifications of Highways are stability (Asphalt content 4.00%-11.00%), Flow (Asphalt content 4.00%-11 0.00%), VIM (asphalt content 4.00%-7.50%), VMA (asphalt content 5.75%-11.00%) and VFB (asphalt content 5.75%-11.00%). As for the Marshall Immersion test, the remaining Marshall stability value is 95.15%.

Abstract

Clean water is the main resource for human needs of good quality for consumption or use in daily activities, including efforts to empower, maintain and protect cleanliness. PDAM Kota Maros is demanded to be able to meet the water needs that are used by living things and the environment. Human needs will increase from time to time due to the increasing number of people needing this water. One way to meet the demand for water is to develop pipelines. In carrying out the analysis of clean water distribution piping networks, tools are needed to make it easier to carry out the analysis, such as the Epanet 2.0 program. The EPANET application is a computer program that provides hydraulic simulations and trends in the quality of water flowing through pipes. This software can model the design of a water distribution network using reservoirs, pumps, valves and connecting lines as symbols of the pipes used. EPANET 2.0 can determine the amount of pressure, flow velocity, and flow rate. In this writing, Graha Cemerlang Housing is used as the object of research on clean water accessible to the people living in Graha Cemerlang Housing. Knowing the need for clean water in Graha Cemerlang Housing in 2021 and knowing that the clean water pipeline network in Graha Cemerlang Housing has been able to serve Graha Cemerlang Housing with the number of houses that subscribe to Graha Cemerlang Housing, namely 330 units having a total requirement of 6.009 l/s and the results of network analysis clean water pipes produce a residual pressure value that meets the hydraulic criteria in 2021.

Abstract

However, along with the pace of population growth and progress in the world of transportation, various problems have appeared. Currently, the problem of traffic congestion has been troubling for road users and has become a widespread problem. This also happened on Jalan Andalas which is the main access road. This study aims to determine the performance of road sections and the impact of side obstacles on the capacity of Andalas Road sections. Data collection is divided into primary data obtained from surveys at the location, namely data on traffic volume, side friction, vehicle speed and road geometry as well as secondary data, namely population data, in data processing using the Indonesian Road Capacity Manual 1997 (MKJI 1997) Urban roads. Based on calculations and analysis of data for 7 days of observation, the largest traffic flow was obtained on Tuesday, namely 1,941.8 pce/hour, the highest side resistance on Tuesday with a total of two directions during the average peak hour flow, namely 342.9 events/hour and the highest degree of saturation is 0.394. The effect of side friction on road capacity is that the greater the side resistance, the lower the capacity and performance of the road segment, conversely if the side resistance is low, the load capacity is large.

Abstract

The purpose of this study was to determine the degree of saturation, the average speed of light vehicles at peak hours, and the actual average speed of light vehicles at peak hours on Antang Raya road in front of Antang market. The method used refers to the Indonesian Road Capacity Guidelines (PKJI 2014). Data collection for 3 days at the research location by videoing traffic volume data, measuring the travel time of light vehicles traveling a distance of 50 m, and counting side friction events. The results of the analysis obtained a degree of saturation of 0.91> 0.85 meaning that the traffic flow on the Antang Raya road in front of Antang Market is jammed. Reading the 2014 PKJI graph shows that the average speed of light vehicles is 27 km/hour, and the calculation of the actual average speed of light vehicles is 8.64 km/hour. The speed of the reading of the graph and the calculation result is very different because the distance traveled by the light vehicles surveyed is 50 m which does not represent the speed of space. For the smooth flow of traffic on Antang Raya road in front of Antang market, it is recommended to install a no parking sign for 200 meters, during peak hours, police officers discipline drivers who are not disciplined, and street vendors selling on the shoulder of the road are neatly arranged so that buyers do not obstruct traffic flow.

Abstract

On Pengayoman road, the traffic flow is dominated by working employees and shoppers along Pengayoman road in the Jl.Bougenville-Jl.Adyaksa segment. This causes traffic conditions to be congested at certain hours and can affect traffic performance. In addition, activities carried out beside the road are also an influence on traffic performance, namely the stopping of public vehicles due to passengers getting on and off, retailers in the road median, and the number of vehicles parking on the road. This study aims to determine the traffic performance of Jalan Pengayoman on the Jl.Bougenville-Jl.Adyaksa section, while the things that need to be studied are the degree of saturation, the average speed value of light vehicles, and the actual average speed value of light vehicle spaces during peak hours. The analysis in this study refers to PKJI 2014. Data collection was carried out for 3 days, namely enumerating traffic volumes, enumerating the incidence of side obstacles, and measuring travel time on light vehicles. The results of the analysis show that the degree of saturation in the west-east direction is 0.37 and the east-west direction is 0.51 which is less than 0.85, meaning that the traffic flow in both directions has not been jammed. Based on the reading of the graph, the average speed of light vehicles in the west-east direction is 56 km/h and in the east-west direction is 52.5 km/h. The calculation of the speed value and the reading on the graph have very different results because the survey distance is too short to get the space speed, which is 50 m. It is recommended that in conducting speed surveys the distance is too short to get the space speed. It is recommended that in conducting a speed survey the distance used for the average speed of space should be more than 50 m to get results that are more representative of the speed of space.
