Abstract

Palangka Raya is the economic center of Central Kalimantan Province, where there are many shopping centers that offer goods at low prices, one of which is the Koperasi Persekutuan Dayak Swalayan which sells daily necessities at low prices and is always visited by consumers so that there is an increase in traffic and tends to result in increased traffic conflict over traffic that is right in front of KPD Swalayan. In this study using two data, namely secondary data and primary data which were analyzed using the PKJI 2014 method. From the results of the analysis of the the percentage of traffic pull due to the KPD Swalayan burdening Jalan Rajawali by 4.34%, the existence of KPD Swalayan results in changes in the performance of roads based on the Degree of Saturation (DJ) = 0,60, Capacity (C) = 1859,70 skr/hour before KPD Swalayan operates after KPD Swalayan operates Degree of saturation (DJ) = 0,57, Capacity (C) = 1859,70 skr/hour, and if the KPD Swalayan is considered non-existent then the side barriers that occur will be reduced so that the Degree of Saturation (DJ) = 0,55, Capacity (C) = 1921,69skr/hour.

Abstract

The main basic ingredients needed for the manufacture of this geopolymer material are materials that contain a lot of silica and aluminia elements. The 1st stage test was carried out to determine the geopolymer paste with the maximum compressive strength at the ratio of NaOH to Na2SiO3 of 1; 1.5; 2; 2.5. The second stage of testing was carried out using a geopolymer paste with the highest compressive strength, namely the ratio of NaOH to Na2SiO3 of 2.5 with a compressive strength of 22.56 MPa. Based on the results of the compressive strength test, the maximum compressive strength at the age of 28 days is 7.64 MPa. The results of the compressive strength of concrete are much lower than the compressive strength of the paste, it shows that the paste does not bind too much with the aggregate. This is evidenced by the results of the compressive strength of conventional concrete which is much higher than that of geopolymer concrete using the same aggregate. With the results of the maximum compressive strength at the age of 28 days is 29.51 MPa.

Abstract

Stagnant water in the highway area is the cause of disruption of the smooth flow of vehicle traffic. Even the overflowing of air from the road creates a large flood supply in the road area. The problem of flooding in the Ijen Bondowoso crater road area was also triggered by the inability of the channel that functions to fill the flood water discharge that occurs in this road area. From this problem, it is necessary to study regarding the adequacy of the capacity of the road channel on roads with a fairly high slope such as what happened in the area of Ijen Crater road, Bondowoso From the results of this study it can be seen that the average daily rainfall is the result of 100,461 mm and the relative average rainfall intensity of each channel for the 10 year return period is 63,301 mm / hour. The flood discharge plan is calculated from 2 to 100 years. In this drainage design analysis, the design flood discharge is calculated for only 10 years, and a planned flood discharge is obtained of 0.423 m3 / second. The channel required to fill the flood discharge is a rectangular channel with the size B = H = 0.6 m. It is recommended to always carry out a comprehensive study with regard to changes in the road body of the road along with the increase in existing traffic. As well as the infrastructure of the existing channel and feeding the community around the road, it will be clean and not littering, especially in the road channel

Abstract

The intake building for Embung Sei Bubu had been designed to be an open channel with the flood gate. The flood gate had been designed from steel with a net width of 1.35 m and the height of the door opening is 0.0076 m. The corrosion is one of the hazardous threat to the strengthness and durability of the flood gate. This research numerically models flood gate that was attacked by pitting corrosion. The pitting corrosion had been modelled in several small holes randomly were distributed on the surface of the flood gate, precisely on the surface of the water. The numerical modeling had been performed in finite element method utilized computer programs such Abaqus. The results showed there was a reduction in the capacity of the steel flood gate due the hole increasing. The reduction in stress capacity had been indicated by the stress concentration that was occured around the pitting corrosion. The stress reduction occured with the change in the percentage of pitting corrosion distribution area of ​​10% (225 MPa), 20% (175 MPa) and 30% (120 MPa)

Abstract

Often we encounter several obstacles that cause traffic concentration at several points on a road segment which causes traffic movement to slow down and even stop. Concentration of traffic flow occurs at intersection points, such as one at the Pilau-Keruing intersection, where traffic moving on the Pilau road is forced to slow down when the traffic flow from Keruing road turns right to cut the flow. Therefore, it is very important to know the effect of turning movement on the smooth flow of traffic. Data collection was carried out by sending several surveyors to the field to obtain secondary and primary data. Furthermore, the analysis of road performance using the 1997 Indonesian Road Capacity Manual. The average space speed obtained from the graph of the relationship between DS and vlv is vlv=28 km/hour. The average speed from the results of the speed survey on the road section gives a value of vlv = 29.6 km / h with conditions without any obstacles to the flow of turning from the Keruing road to the Pilau road, and vlv = 25.6 km / h with the presence of turning current obstacles . There was a decrease in average travel time of 5.9 seconds, with a decrease in traffic speed of 4 km/hour due to the influence of vehicles turning from Keruing road to Jati road.

Abstract

Fosroc Conplast R and Fosroc SP 337 are additives for the concrete mixture which are used to delay the setting time of the concrete mixture, thus, it can extend the time for the concreting work. Previous studies have verified that the addition of Fosroc SP 337 and/or Fosroc Complast R additives increases the compressive strength of concrete, but no previous studies have investigated the effect of adding these additives on the compressive strength of concrete with variations in water-cement ratio. Therefore, this research is conducted to investigate the effect of adding Fosroc Conplast R and Fosroc SP 337 additives on the compressive strength of concrete with variations in water-cement ratio, by conducting the test on properties of the materials for designing the concrete mixture proportion, then the compressive strength test is conducted and the compressive strength of concrete is compared with the design compressive strength based on SNI 03-2834-2000. The compressive strength test was conducted at the concrete age of 7 and 28. Concrete with the addition of 1% Fosroc Conplast R and 1% Fosroc SP 337 additives, produces a higher compressive strength than the design strength of normal concrete without additives, thus, this additive is applicable to extend the time for the concreting work in the construction field

Abstract

In every building, a foundation is needed as a strong and sturdy building foundation. The foundation aims to support the building and pass the load on the building above it to a layer of soil that is strong enough to have a bearing capacity. To calculate the carrying capacity of the soil, there are many formulas that can be used. The results of each of these formulas produce different carrying capacity values. The purpose of this study is to calculate and analyze the bearing capacity of shallow foundations from the results of hand boring with the Terzaghi and Meyerhof methods. The results showed that the carrying capacity of the shallow foundation soil in the Terzaghi method was smaller than that of the Meyerhof method. The value of the terzaghi method is 353,443 KN /m2, while the Meyerhof method has increased by 70,094%, with a value of 601,185 KN /m2.
