Abstract

We investigate a graph labeling called the total vertex irregularity strength (tvs(G)). A tvs(G) is minimum for which graph has a vertex irregular total -labeling. In this paper, we determine the total vertex irregularity strength of disjoint union of ladder rung graph and disjoint union of domino graph.

Abstract

The ADHD  is a hyperactive individual and tends to respond excessively. In identification, the therapist only observes the child's development. The results of the therapist's observation will show that the child has ADHD Collection of characteristics in the identification and intervention based on the literature and questioner.The tracking method used is forward chaining and the method of calculating the certainty value is certainty factor. The result of the research is a web-based ADHD identification system .Application was made to help parents and therapists in identifying ADHD, on test data that resulted in hyperactive child identified with 98.953% confidence level percentage, inatentive with confidence percentage of 83.354% and impulsivity with percentage of confidence 92,067 %Keywords: System, Expert, ADHD, Forward Chaining, Certainty Factor

Abstract

This research implements a fuzzy topsis based system for selecting the best employees at PT. Delta World Textil. One of the matters, especially in the management of Human Energy Resources (HR) is the selection of the best employees periodically, so that those who are elected will be given an award in the form of a bonus in order to motivate employees to improve their service and performance. The best and quality employees are the legacy of the industry that wants to make the industry grow rapidly. Several methods have been proposed for selecting the best employees. However, the method used is inaccurate because it only uses one method with few criteria. This study aims to select the best employees by looking at several criteria in the form of discipline, teamwork, attitudes, presence, skills, loyalty, tenure, and productivity for initial processing using fuzzy logic. Initial values are obtained in the form of membership function values which are used as input into the topsis method. The first stage of the topsis method is carried out in the normalized decision metric stage, the results of this stage are used to find a weighted normalized decision matrix according to the weight of the criteria for each criterion, the results of this stage are used to ensure positive ideal solving and negative perfect solutions after that the distance between the values is determined. each alternative with a positive perfect solution matrix and a negative perfect solution matrix. In the last session, the highest preference value was sought so that the best employees were obtained. The results show that the system established is very feasible in ensuring the best employees in performance evaluation. Keywords : Fuzzy Logic, Topsis, Best Employees, Decision Support System

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui model peramalan yang paling baik digunakan untuk meramalkan inflasi di Indonesia dengan data inflasi Januari 2015 sampai dengan Mei 2020. Penelitian ini menggunakan beberapa metode peramalan. Berdasarkan metode peramalan yang dilakukan didapatkan hasil peramalan yang paling baik dilihat dari MAPE, MAD dan MSD adalah single exponential smoothing. Selanjutnya, hasil peramalan menunjukkan bahwa tingkat inflasi di Indonesia pada Agustus 2020 sebesar  1,41746%.

Abstract

Tujuan penelitian ini adalah menerapkan data mining pada jumlah penduduk miskin di Indonesia dengan data 2006 sampai Maret 2020. Akan dilakukan analisis cluster dengan metode k-menas kemudian dilakukan prediksi pada jumlah penduduk miskin di Indonesia. Hasil penelitian menunjukkan bahwa dengan analisis cluster metode k-means diperoleh dua cluster. Selanjutnya, berdasarkan prediksi yang telah dilakuakan dengan double exponential smoothing dengan nilai Alpha 1,094 dan Gamma 0,539, diprediksi periode selanjutnya terdapat 27,4405 juta jiwa penduduk miskin di Indonesia.

Abstract

Let G = (V, E) be a graph. The distance d (u, v) between two vertices u and v is the length of the shortest path between them. The diameter of the graph is the length of the longest path of the shortest paths between any two graph vertices (u ,v) of a graph, . In this paper we propose algorithms for finding diameter of a hierarchy graph using DFS. Diameter of the hierarchy graph using DFS algoritm is four.
