Abstract

Optimization is the best decision making activity that can be carried out by the company related to the industry in question within existing limitations by involving limiting determinant variables. The problems faced by UD Pastijaya are the limitations that exist in an effort to maximize the production of roof tiles by optimally using the variable variables available to obtain an increase in tile production. The solution that can be done is to use the Goal Programming method which is the development of the Linear programming method. This method is used to solve the problem of determining the amount of optimal production with limited resources as targets to be achieved. The optimization results are carried out by using the POM-QM assistance application. The number of tile production has increased in several types of tiles including coral reefs as many as 52425 units, press as many as 51955 units, morando as many as 12441 units, and wuwung as many as 9310 units. Keywords: Production optimization, tile, Goal Programming

Abstract

One of the main activities of block ice production is the process of freezing ice blocks in the brine tank. Brine Tank is a tank that functions to freeze ice blocks. Brine Tank contains salt water. Mathematical modeling is a formulation of mathematical models that describe how to get a solution to a mathematical problem in a natural event. Mathematical modeling can form mathematical models that describe the process of ice freezing in brine tanks in accordance with actual conditions without ignoring important factors in the system. The mathematical model in the process of ice freezing in the Brine Tank is obtained from the momentum equation and the energy equation which is solved using the finite volume method. In this study a mathematical model was built to determine the effectiveness of time in the ice freezing process in the brane tank.

Abstract

This study aims to describe the creative thinking process of blind students in constructing plane figure assisted by tangram props according to the stages of Wallas. The research subjects were three blind students of VIII grade SLB-TPA Negeri 1 Branjangan. Data collection methods used were test questions constructing plane figure and interviews. Based on the analysis of the results of tests and interviews shows that students of S1, S2, S3 through all the processes of creative thinking according to the Wallas’s stages include the preparation stage, the incubation stage, the illumination stage, and the verification stage when resolving problems constructing plane figure. At the preparation stage, blind students tend to lack understanding of the initial information such as explaining the problem given. At the incubation stage, blind students need a long time to do the process of pondering thinking about solving the problem in question. At the illumination stage, blind students are able to get two or more different ideas for completion. Blind students tend to use trial and error to find an idea. At the verification stage, blind students tend to re-check the answers obtained to reassure the answers are correct.

Abstract

Bronchial asthma is a disease of the narrowing of the airways located in the human bronchi. One of the factors causing this narrowing is Particulate Matter 2.5. Particulate Matter 2.5 is a kind of particle with dust that can cause narrowing of the airways. These particles are very small, ie less than 2.5 micrometer and can enter the lungs. Mathematical modeling is a way of solving problems that describe a mathematical solution in the real world. Mathematical modeling can form a mathematical model that describes the flow of air on the bronchi due to bronchial asthma according to actual conditions and important influences in them. In this study formed a mathematical model of bronchial air flow due to bronchial asthma. Mathematical models are obtained from the momentum and mass equations which are solved using the finite volume method. Keywords: Asthma, Mathematical modeling, Finite volume

Abstract

This study aims to analyze the stages of creative thinking of students with choleric personality types in solving Algebra problems. This type of research is qualitative research. Students with choleric personality types are given Algebra questions followed by interviews to explore information in students' creative thinking processes. The results obtained are students capable to form a mathematical model of the information contained in the problem using the Algebra symbol at the preparation stage. Students are capable to find more than one settlement idea by utilizing the equations formed in the problem and require a short time to understand the problem at the incubation stage. Students are capable to write the completion steps containing Algebra operations systematically at the illumination stage. Students are capable to recheck the answers generated by substitute the value of the variable sought into an equation well at the illumination stage. The conclusion of this study is that choleric students are capable to fulfill all the indicators at the Wallas creative thinking stage. This can be seen from the results of the Algebra test given and the results of the interviews that have been conducted.

Abstract

The problem-solving profile is a general description of the activities of solving mathematical problems carried out by students using the five stages of IDEAL model problem solving namely identifying problems, defining problems, finding solutions, implementing strategies, and reviewing and evaluating their effects. This becomes interesting when it is associated with mathematical abilities. This study aims to describe the profile of students with high mathematical ability in solving questions about the subject of Social Arithmetic. This type of research is qualitative research. Students with high mathematical ability were given two problem-solving test questions, then interviews were conducted to find out more in the process of solving them. The results obtained are students with high mathematical ability able to meet all the indicators of each stage of solving the IDEAL model. This can be seen from the results of the work provided and interviews conducted by researchers against these students.
