Abstract

Kruskal's algorithm in searching for minimum spanning trees can be applied to pipelines installed at the location of PDAM Tirtanadi Tuasan where problem identification starts with the water discharge reaching the consumer is small but the discharge flowing from the reservoir is sufficient, so this research is used as a solution to this problem and also as an optimization of the clean water distribution network in the Tirtanadi Regional Drinking Water Company (PDAM) of the Tuasan Branch with the intention of cutting the direction of the pipe flow to overcome this problem. The data obtained from PDAM Tirtanadi Tuasan Branch is in the form of a floor plan and formed into a weighted graph. After the data is obtained, then it is calculated manually that the length of the installed water pipe is 32,645 m with 86 vertices and 100 edges, then the pipe length is represented as a set of paths and the pipe connection ends are represented as nodes. The pipe length obtained using Kruskal's algorithm and inspection of iterations using the QM for windows software is 22,095 m, with 86 vertices and 85 edges. So, using the Kruskal Algorithm and the help of the QM for windows software, the difference in pipe length obtained is 10,610 m.

Abstract

The rapid development of vehicles has an impact on increasing the need for parking space, thus demanding the need for availability and land management that provides convenience and comfort for motorists. Plaza Medan Fair mall is still not optimal in planning and managing parking lots, this can be seen from the number of vehicles that do not get parking spaces while parking is still available, besides that the placement of parking cars has not been arranged so that visitors still have difficulty in finding a parking space. This can have an impact on not optimal parking lot income. Parking lot management can be done by classifying parking by categorizing vehicles according to their group considering that each vehicle has a different size and can be grouped according to type. Optimization of parking management can be done using the branch and bound method integer program. The branch and bound method is a method to find the optimal solution to the integer problem with the concept of branching and bounding. The results of the study found that there were 200 parking spaces for small cars, 651 parking spaces, 651 parking spaces, 226 large cars and 70 parking spaces. The maximum parking income obtained by Plaza Medan Fair mall is Rp10,023,000.-.

Abstract

Employee performance appraisal system is a system used to assess the best performance of employees. PT Graha Prima Medan performs the best performance assessment of employees to evaluate, verify and improve their performance. The results of this performance become a decision-making tool such as promotion, dismissal, transfer, intensive giving or providing feedback for employees. However, the large number of employees who will be selected becomes an obstacle in assessing employee performance, because it is expected that an automation process uses technology to evaluate the performance of these employees. The purpose of this study is to design an employee performance appraisal system at PT Graha Prima Mentari Medan. The method used is the SAW method, the basic concept of the SAW method is to find the weighted sum of the performance ratings for each alternative on all attributes. The SAW method can help decision making to form the largest value as the best alternative. The assessment in the research that has been carried out uses 5 criteria including: Attendance, Attitude, Time Discipline, Working Period and Quantity using the SAW method. In this study, testing was carried out on 36 respondent data. The employee performance appraisal system was developed using the PHP (Pre-Hypertext Processor) programming language, and the MySQL database as the database server.

Abstract

This study offers a new technique for constructing percentile bootstrap intervals to predict the regression of univariate local polynomials. Bootstrap regression uses resampling derived from paired and residual bootstrap methods. The main objective of this study is to perform a comparative analysis between the two resampling methods by considering the nominal coverage probability. Resampling uses a nonparametric bootstrap technique with the return method, where each sample point has an equal chance of being selected. The principle of nonparametric bootstrapping uses the original sample data as a source of diversity in contrast to parametric bootstrapping, where the variety comes from generating a particular distribution. The simulation results show that the paired and residual bootstrap interval coverage probabilities are close to nominal coverage. The results showed no significant difference between paired bootstrap interval and percentile residual. Increasing the bootstrap sample size sufficiently large gives the scatterplot smoothness of the confidence interval. Applying the smoothing parameter by choice gives a second-order polynomial regression with a smoother distribution than the first-order polynomial regression. The scatterplot shows that the second-degree polynomial regression can capture the data curvature feature compared to the first-degree polynomial. The bands made from second-degree polynomials give a narrower width than first-degree polynomials. In contrast, applying optimal smoothing parameters to the model provides different conclusions by using smoothing parameters based on choice. In addition to the differences based on the scatterplot, the bootstrap estimates of the coverage probability are also other. Selecting smoothing parameters based on a particular value provides probability coverage with the paired bootstrap method for the first-degree local polynomial regression is 0.93, while the second-degree local polynomial is 0.96. The probability of coverage based on the residual bootstrap method for the first-degree local polynomial regression is 0.95, while the second-degree local polynomial is 0.96. The probability coverage based on the optimal parameters of the paired bootstrap method for the first-degree local polynomial regression is 0.945, while the second-degree local polynomial is 0.93. The residual bootstrap method gives the first-degree local polynomial regression of 0.95, while the second-degree local polynomial is 0.93. In general, both bootstrap methods work well for estimating prediction confidence intervals.
