Abstract

Stunting is a condition of failure to thrive in toddlers due to chronic malnutrition, resulting in toddlers or children being too short for their age standards. The purpose of the study was to determine the factors that influence the incidence of stunting to toddlers at the Public Health Center Kasih Ibu airtiris, kampar. The method used in this study is the binary logistic regression method. Based on the results of the study indicate that the factors that influence the incidence of stunting in toddlers at Public Health Center Kasih Ibu airtiris, kampar namely the nutritional status of body weight based on age. The binary logistic equation with the resulting logit function is . The value of the determination of the classification of stunting events using binary logistic regression is 83,6%.

Abstract

This research aims to derive the general form of the trace matrix of adjacency from star graphs and complete bipartite graphs with size n × n and raised to a positive integer power. To obtain the general form of the trace matrix of adjacency for these graphs, we first derive the general form of the adjacency matrix raised to a positive integer power for each given graph. The general form 14 of matrix exponentiation is proven using mathematical induction. The trace matrix of adjacency for each graph raised to a positive integer power is obtained through a direct proof based on the definition of the trace matrix. Additionally, applications of the trace matrix of adjacency from star graphs and complete bipartite graphs with size n × n and raised to a positive integer power are provided in the form of examples.

Abstract

UD Kirana is a trading business that produces rattan weaving in Rumbai district which consists of 5 types of products produced, namely guest chairs, terrace chairs, tender chairs, serving hoods and baskets. In the rattan woven production process, UD Kirana cannot predict how many items can be produced each week so that maximum profits have not been achieved.This research aims to find out how goods can be produced every week in order to get maximum profits.The methods used are the Round Off method and the Cutting Plane method. Based on the research result, UD Kirana produced 10 tender chairs, 7 serving hoods and 21 baskets with a profit of Rp. 6.060.000. The Round Off method is more efficient than the Cutting Plane method, this can be seen from the addition of constraints, namely the Round Off method adds two constraints and the Cutting Plane method adds three constraints or gomory constraints.

Abstract

Diabetes Mellitus (DM) is a chronic condition or disorder of metabolism caused by various factors and characterized by elevated blood sugar levels, accompanied by dysfunction in the metabolism of carbohydrates, fats, and proteins as a consequence of insulin function impairment. Ibn Sina Hospital in Pekanbaru provides care for patients suffering from diabetes mellitus by implementing a type IV diet with normal nutritional status and IMT ranging from 18 to 25. In the food production process, Ibn Sina Hospital uses raw materials such as rice, fish, tempeh, broccoli, and bananas. The aim of the research is to find out the minimum costs that mush be incurred for food raw materials at Ibnu Sina Pekanbaru Hospital for patients suffering from diabetes mellitus. The applied methods involve The Two-Phase Simplex Method and The Quick Two-Phase Simplex Method. According to the findings of this research, The Two-Phase Simplex Method requires 5 iterations, while The Quick Two-Phase Simplex Method only requires 1 iteration to obtain optimal result. So The Quick Simpleks Method is more efficient than The Two-Phase Simplex Method because it is seen from the number of iterations carried out.  In both methods, it is determined that the minimum production cost of food raw materials for diabetes mellitus patients is Rp. 9,138.5.
