Abstract

There are various kinds of development projects in construction projects in Bukittinggi, one of which is the construction of a culinary center, The project location is in the city center area, and around the project there are many people selling it is important to identify undesirable risks so that they do not hinder or cause failure in the implementation of the project. Data analysis using the Severity Index method has the aim of determining the probability (P) and impact (I) categories. SI  calculated based on the answers of all respondents. Next, they are categorized based on the magnitude of the probability and impact calculation results into the Probability Impact Matrix, which describes the level of risk that has been identified. Evaluation of the probability and impact of each risk is carried out using a probability and impact matrix which determines the combination of probability and impact that leads to the lowest, medium risk level. , or high. The results of the analysis showed that 1 risk was in the low category, 2 risks were in the high category, namely errors in the initial survey and errors in cost estimates. 15 risks are in the medium category, which is the dominant risk level. For risk response to high risk levels, it is necessary to consider minimizing errors by transferring them because if an error occurs it will have a huge impact on project .Keywords: risk;severity index; probability.

Abstract

Planning for the Upper Structure of the MTsN III School Building in Pasaman Regency aims to have a building with good capacity and quality that meets the Indonesian National Standard (SNI). This plan plans the construction of a building structure to achieve a plan that is strong, safe, and fulfills the requirements set out in the regulations that apply to building structure planning. The Planning of the Upper Structure of the MTsN III School Building in Pasaman District was a preliminary design using SAP2000. Loads that are input into SAP2000 are dead loads, live loads, building's own weight, earthquake loads. From the preliminary design results, the results obtained are beam reinforcement (B1) size 30 x 50 with concrete quality 250 MPa, steel quality 420 Mp, reinforcement used 18D19, beam (B2) size 25 x 40 with reinforcement used 16D19, column size 40 x 40 the reinforcement used is 12D19, the floor slab uses D10 reinforcement with a floor plate thickness of 13 cm, stirrup reinforcement D10, the thickness of the concrete cover is 40 mm. From the planning above, it can be concluded that it has fulfilled the terms and conditions in Indonesian regulations and standards.Keywords: Structure of Beams, Columns, Floor Slabs, Loading, Reinforcement.

Abstract

Roads play a very important role in people's lives in supporting the pace of the economy and regional development. If there is damage to the road it can cause an accident. The aim of this research is to determine the types of damage and index values for the Nagari Talu road, West Pasaman Regency, so that it can compare the road condition values based on two methods, namely, the PCI (Pavement Condition Index) method and the Bina Marga method. The assessment of road conditions using the PCI method is ranked from 0-100, while the Bina Marga method is based on the order of road priority with a value range of 0-7. The types of damage found on the 2 km long Nagari Talu road included holes, crocodile skin cracks, longitudinal cracks, transverse cracks, patches, loose grains and wavy ones. In the PCI method, the average value of 57.14 is good road conditions. In the Bina Marga method, the priority order value is 5.35, so the road is under periodic maintenance.Keywords: Road damage analysis, PCI method, Bina Marga method, Jalan Nagari Talu West Pasaman Regency.

Abstract

On a micro basis, there are several efforts to minimize the problem of traffic movement, especially on the safety and comfort on the road, which can be done by installing a median to separate the traffic flow in opposite directions. In planning the median, it is necessary to prepare a median opening that allows the vehicle to change the direction of travel in the form of a reversal movement or termed a U-Turn movement. One of the effects when doing a U-Turn is the speed of the vehicle where the vehicle will slow down and stop. This slowdown will affect traffic flow in the same direction, this circular movement will cause high traffic volume, lower vehicle speed, and higher density on the road. The author took the research location on roads in the West Payakumbuh District, Payakumbuh City, West Sumatra Province which dotted on the Soekarno-Hatta road section, Parit Rantang Payakumbuh City.The purpose of this study is to determine the performance of the road segment and the level of road service equipped with U-Turn facilities, analyze the average travel time of vehicles performing U-Turn, vehicle speed when performing U-Turn and queue lengths for U-Turn activities. To achieve this goal, the 2014 PKJI method was used. From the results of this study, it was found that the average travel time of the largest vehicle when making a u-turn was 12.68 seconds with a vehicle speed of 1.25 km/hour, with a queue when doing a u-turn of 50 meters. With service level C.Keywords: U-turn, travel time, speed, queue, level of service

Abstract

Volcanic ash contains mineral chemical elements such as Aluminum (Al), Silica (Si), Iron (Fe), Calcium (Ca), and Magnesium (Mg) which have bonding force when mixed with cement. This research aims to look at the presentation of the use of volcanic ash as a concrete construction material. The volcanic ash used was obtained from the eruption of Mount Marapi, West Sumatra, which was then mixed with Portland cement with a composition of mixing volcanic ash and cement 10% + 90%, 20% + 80%, and 30% + 70%, those characteristics were then seen based on spectrometric analysis. X-ray Diffraction (XRD). Based on the XRD test results, it can be seen that the volcanic ash from Mount Marapi, West Sumatra, has a composition of silica (SiO2) and alumina (Al2O3) which is proven to have pozzolanic properties. From the three mixtures, it can be seen that the highest XRD’s peak is quartz because of the high content of silica and oxide. These three mixing variables have been proven to be used as the basis for mixing for concrete formation. Keywords: Volcanic Ash, Mixing, Cement,  XRD
