Abstract

People’s Business Credit (KUR) is vulnerable to unwanted risks such as bad credit. The reduce bad credit, banks need to analyze whether customer debtors meet the requirements for credit. The aim of this research is to determine the logistic regression analysis model and determine the factors that influence the provision of People's Business Credit (KUR) at Bank BRI Unit Tangkerang Pekanbaru. The method used is the Logistic Regression method. Based on the research results, it was found that the factors that influence the provision of People's Business Credit (KUR) at Bank BRI Unit Tangkerang Pekanbaru are business turnover and business profit. So the logistic equation is obtained with the resulting logit function being g(x) = -11.587+0.501x_1+2.549x_2. The calcification value for granting People's Business Credit (KUR) using logistic regression is 93.84%.

Abstract

Retno bakery Bread Shop is one of the shops that produces various types of bread. This bakery has not used a inventory control system in the production process so it cannot meet customer needs. For this reason, Retno Bkery Bakery needs to control inventory so that the company's performance and profits are more optimal. This study discusses the control of the inventory of each bread raw material such as flour, sugar, milk, yeast, salt, butter and eggs. The purpose of this study is to obtain the results of the total cost of bread raw material inventory using the Economic Production Quantity (EPQ) method and the Just in Time (JIT) method as well as the comparison of the two methods used. The methods used are the Economic Production Quantity (EPQ) and Just in Time (JIT) methods. Based on the results of the study, the percentage difference in cost for each raw material was obtained using the Economic Production Quantity (EPQ) method and the Just in Time (JIT) method, namely for flour raw materials of 42.05%, sugar 47.31%, milk 51.63%, yeast 51.83%, salt 47.65%, butter 51.38% and eggs 51%. Thus, the Just in Time (JIT) method results in a smaller total cost than the Economic Production Quantity (EPQ) method.

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%.
