Abstract

This study aims to determine how the properties of non-sand concrete with variations in the amount of mixing fly ash. This property was analyzed by compressive strength test. We also do calculations using the MATLAB application with interactive script methods. There are 16 numbers of test objects conducted in this study. The specimen is cylindrical with a size of 7.5 cm and a height of 15 cm. Flying ash variations used ranged from 0%, 25%, 50%, and 75%. In this research, we use 1: 6 between cement and gravel. The results of the average compressive strength obtained in the mixture of 0% fly ash are 1,172 MPa, 25% 0.871 MPa, 50% 2,367 MPa and 1,465 MPa for mixture of 75% fly ash. The best compressive strength results on the 50% fly ash mixture. The density is also affected by the mixing of this fly ash. The greater the mixing of the fly ash, the smaller the density value. Keywords: compressive strength, density, fly ash, MATLAB

Abstract

Abstrac This research was conducted to determine the effect of the addition of waste shells and shell powder glass powder on the compressive strength of concrete. The method used is to use the experimental method by making test specimens with a mixture of waste shells powder shells and glass powder by 4%; 8%; 12% then compared with normal concrete without added ingredients. Concrete specimens that have been soaked then tested their compressive strength with the age of 7 days, 14 days, 21 days, and 28 days. The results of the test showed that normal concrete which was not added with the waste of shell powder and glass powder had compressive strength under mixed concrete variations of 4%, 8%, and 12 % when the concrete was 28 days old. Concrete which is added with waste of shell powder and glass powder has  a high yield at 4% variation that is equal to 20,66 MPa. For concrete Variasi of 8% has a compressive streng value of 20,17 MPa, For variations of 12% has a compressive strength value of 20,46 MPa and for normal concrete has a compressive strength of 20,16 MPa at the age 28 days. The compressive strength value generated by the research that occurs due to the slump test value factor that is done is not the same.                       Keywords: Concrete, scallop waste powder, Glass powder waste, concrete compressive strength.

Abstract

This paper contains an analysis of the loading and the position of rock in the bridge foundation based on the rock's response to the force that will be tested with "Graphic User Interface (GUI)" program using MATLAB. This paper also explains the preparation of bridge foundation modeling based on the forces tested on the rock named ‘x’. The response forces discussed in this paper are normal force, latitude force and moment force.                 The data is processed using MATLAB software and then presented in the form of tables, graphs and 2D modeling that shows the loading and the position of rocks correspondence to the bridge foundation. After obtaining the rock’s ‘x’ data, the data is then processed using Graphic User Interface program, through the program moment force graphs, normal force graphs, latitude graphs can be obtained which later these results can be considered for modeling the loading and the position of the rock’s ‘x’.                 Through the data processing that has been done, zero normal force is obtained, and the latitude has a value of about (0 to 8) N and the moment force of about (-60 to 0) N. Based on these calculations it was found that the rock’s 'x' can be modeled by arranging it rectangle with center of gravity evenly distributed at the center. And the model that are used is the placement pinch model because it does not have translational and rotational values so that the rock ‘x’ is suitable to be the bridge's foundation.Keywords: Shear forces, Bending Moment, Normal Forces, GUI, Modelling

Abstract

Abstract Rigid Pavement is the main work in toll road construction. In the implementation of rigid pavement, there are several alternatives, namely mechanical and conventional, where each alternative has advantages and disadvantages. This study aims to determine the selection of appropriate work methods on the Kunciran - Cengkareng Toll Road Project. Many multi-criteria must be considered, the consideration of decision making can be done by using the Technique For Others Preference By Similarity To Ideal Solution (TOPSIS) method and Fuzzy Analytical Hierarchy Process (FAHP) which can give weight to the specified criteria. The objectives of this study are: (1) to find out the most influential criteria as a basis for considering the selection of methods for implementing rigid pavement works. (2) to determine the method of implementing rigid pavement work that is appropriate by the existing criteria. This study uses a questionnaire survey. The results of this study indicate that the criteria for quality of work are the most influential criteria with a value of 0.351, then the implementation time criteria (0.201), the criteria for work costs (0.150), work safety criteria (0.133), work volume criteria (0.084), implementation process criteria (0.049), and the last is the implementation preparation criteria (0.032). The appropriate alternative used for the rigid pavement method is the mechanical method with a value of 0.621, while the mechanical method only reaches the values of 0.379.. Keywords: Fuzzy AHP; Perkerasan Kaku; TOPSIS.
