Abstract

Road geometric design is part of road engineering, with a focus on the engineering design of the physical form of the road to realize the basic function of the road. Road geometry design products include horizontal alignment, vertical alignment, and road cross sections. The geometric design of the road takes into account traffic safety and comfort in accordance with the function of the road. Estimated traffic flows include motorized vehicles, bicycles, and pedestrians. Road construction in developing countries aims to connect isolated areas and encourage economic growth through better population mobility. Therefore, the government needs to be encouraged. This key element focuses on achieving a balance between regional development and national security for national development. Without sufficient access, it will be difficult for people to conduct activities with different parties. When planning grade curves to improve road safety, attention is paid to the type of curve, the condition of the ground contour to avoid slopes and rivers, and the average speed of road users, all of which affect the minimum circle radius. The minimum circle radius value is a factor that affects the sharpness of the road's horizontal curve at a later stage, if the minimum radius is used then the curve will be very sharp. Therefore, the required turn value needs to be considered and adjusted to the standard so that the horizontal curve of the road is not too steep for the user.

Abstract

The road is a facility that is very important for the community to achieve a desired goal, for that we need a road that is safe and comfortable for its use. Road damage often occurs every year, especially on roads that are often traversed by vehicles with a lot of volume (congested ) and vehicles that are heavily loaded (overloaded) such as on the Sukahaji – Maja road, which causes the speed of users to slow down (drop) and have an impact on reducing population mobility and the economy of the surrounding community. The purpose of this research is to determine the level of road damage using the Payment Condition Index (PCI) method. The survey method or PCI refers to ASTM D6433 (Standard Practice for Roads and Parking Lots Pavement Condition Surveys). Pavement Condition Index (PCI) is a road pavement condition assessment system based on the type, level, and extent of damage that occurs and can be used as a reference in maintenance efforts. This PCI value has a range of 0 to 100 with the criteria of excellent, very good, good, fair, poor, very poor, and failed. Based on the analysis using the PCI method, for the type of damage that occurs on the Sukahaji-Maja road for the flexible pavement/asphalt type, 6 types of damage occur, namely alligator cracking, striping, grain release, collapse, vanished, and potholes. In Table 4.2 the average PCI value obtained is then entered into the parameters as in the table so that the road can be categorized as damaged, namely Poor (Damaged). So this road needs to be included in a road improvement program on an ongoing basis.

Abstract

In Majalengka Regency, the Laswi road is an access road that connects the Tonjong Roundabout with the Tonjong Kecap Monument. The pavement on Jalan Laswi uses flexible pavement. The road was damaged due to the large number of heavy and light vehicles that passed through it. It is anticipated that the assessment of road damage conditions will be able to assess the degree of road damage on a section of the road. The purpose of this study is to determine the appropriate method of handling road damage and the level of damage that occurs. The PCI method (Pavement Condition Index) is used to assess the condition of road pavement damage. This method involves a visual survey of the damage and evaluating it according to type, extent, and amount. The damage can be used as a basis for performing maintenance and repair tasks. By using the PCI method, research on road conditions in Laswi (Majalengka Regency) found that the average PCI value for all Laswi road sections was 82,38% (Very Good).

Abstract

The planning for the Hotel Building in the Harau Valley Natural Tourism Area consists of 5 floors. The function of this building planning is to support the implementation of the planned structural element consisting of floor plates, beams, columns and foundation. Guidelines for planning reinforced concrete buildings. SNI 1726- 2019 for planning earthquake loads and SNI 1727-2020 for planning loads on buildings. In this plan, concrete quality Fc’ = 25 Mpa is used, threaded reinforcement uses steel quality 420 Mpa and plain reinforcement with steel quality 280 Mpa. From the results of the calculations that have been carried out, it can be seen that the thickness of the floor plate is 120 mm and for the roof plate it is 100 mm thick, while the beam is 30/60 cm with D22 main reinforcemen, the beam with dimensions 35/70 cm uses D22 main reinforcemen and the dimensions of the joist area 20/35 uses D16 main reinforcemen and uses Ø10 for stirrup reinforcemen. For foundation planning, use a boredpile foundation. Analyze the structure in this planning using the SAP 200 v.14 aplication.

Abstract

Rainfall plays an important role in planning water structures, be it drainage, irrigation, dams, etc. Testing rainfall data is useful for reducing the risk in planning water structures to be built. The rainfall data used was obtained from the PSDA of West Sumatra Province with 3 closest station points for the Pyakumbuh City area (Canduang Station, Tanjung Pati Station, and Suliki Station) over a period of 10 years (2013-2022). The RAPS and Double Mass Curve methods were used for consistency tests, while the T-test was used for Homogeneity tests. The results of the Double Mass Curve Consistency test at Suliki Station showed that the rainfall data was consistent, while at Tanjung Pati Station and Canduang Station it was inconsistent, so a correction factor was needed so that it was obtained at both stations consistent. While the consistency test U used RAPS method against preliminary rainfall data and that has been corrected obtained data results already consistent with mark as following : Q count < Q critical = 1.48 < 3.60. Q count < Q critical = 1.92 < 3.60. Q count < Q critical = 2.14 < 3.60. Q count < Q critical = 1.87 < 3.60. Q count < Q critical = 1.75 < 3.60. Meanwhile, the results of the RAPS method Consistency test show that the rainfall data from the three stations are consistent throughout the observation period. For the results of the Homogeneity test using t-test is as as follows : t count < t critical = 1.168 < 1.734. t count < t critical = 0.721 < 1.73. t count < t critical = 0.435 < 1.734. t count < t critical = 0.387 < 1.734. t count < t critical = 1.702 < 1.734. t count < t critical = - 0.071 < 1.734. From the calculation of the Homogeneity test of the t-test method, it shows that the rainfall data from the three rainfall stations did not experience significant changes throughout the time period, indicating that the data from the three rainfall stations were homogeneous. The results of the consistency test and homogeneity test showed that the rainfall data from the PSDA of West Sumatra Province were consistent and homogeneous.
