Analyzing the use of Social Media by Fashion Designers with K-Means and C45

Social media is one part of digital marketing that is used for the development of marketing business products known as social-marketing. The use of social media as social marketing is still managed conventionally and has not implemented business social media. This study was conducted to analyze the clusters and classifications of the use of social media by fashion designers in West Sumatra in marketing their products. This analysis uses the k-Means algorithm and c45 uses the Rapidminer application for the fashion designer industry in West Sumatra. Data is collected from Instagram and Facebook of fashion designers. The data analyzed by K-Means resulted in 3 clusters of social media use, namely 3 less active clusters, 12 active clusters and 1 very active, then classification using the C45 method resulted in a decision tree that described the most and the least in using social media. This study resulted in grouping and classifying variables from whether or not the use of social media in social marketing for the fashion designer industry players in West Sumatra was good or not. The results of this study can be used as a reference for developing integrated marketing for West Sumatra fashion designers

Time-Fractional KdV Equation for the plasma in auroral zone using Variational Methods

The reductive perturbation method has been employed to derive the Korteweg-de Vries (KdV) equation for small but finite amplitude electrostatic waves. The Lagrangian of the time fractional KdV equation is used in similar form to the Lagrangian of the regular KdV equation. The variation of the functional of this Lagrangian leads to the Euler-Lagrange equation that leads to the time fractional KdV equation. The Riemann-Liouvulle definition of the fractional derivative is used to describe the time fractional operator in the fractional KdV equation. The variational-iteration method given by He is used to solve the derived time fractional KdV equation. The calculations of the solution with initial condition A0*sech(cx)^2 are carried out. Numerical studies have been made using plasma parameters close to those values corresponding to the dayside auroral zone. The effects of the time fractional parameter on the electrostatic solitary structures are presented.Comment: 1 tex file + 5 eps figure

ALGORITMA K-MEANS CLUSTER UNTUK SEGMENTASI PELANGGAN

Consumer data for business transactions in retail agricultural products has not been managed digitally. This can be seen from consumer data which is still stored manually, some customer data is stored only based on purchase receipts and others have logbooks so that consumer data can be lost at any time. To improve service to consumers, sales analysis is carried out using the k-means algorithm. The aim is to be able to group consumers based on the number of transactions, the number of products purchased, and the frequency of transactions made. The data processed was 127 transaction data and grouped by name of the consumer, 116 consumers made transactions in the last 1 months. From this data, 5 clusters were determined including: Superstar, Golden, Typical, Occasional, Everyday. Of the 5 clusters, there were 4 consumers including Superstar, 12 Golden consumers, 34 Typical consumers, 29 Occasional consumers and 37 Everiday consumers

FUZZY LOGIC TO OPTIMALIZED THE PRODUCTION OF SANJAI FOR INCREASE THE BENEFIT IN SMALL MEDIUM ECONOMICS

The company's decision in a subsequent period depends on the rest of the supplies from a previous period and also the estimated number of supplies at one period. The number of demand and supply is an uncertainty. Fuzzy logic is one of the science that can analyze the uncertainty. One method of fuzzy rules are Mamdani, a method often used to build a system that resembles the necessary instuisi or human feeling. The calculation process is quite complex so it takes a relatively long time, but this method gives results with high-precision values. Keripik Balado Christine Hakim is a company that did the production in large quantities every day. The maximum profit obtained from the sale of a maximum, when the number of production by the company is less than the number of requests the company will lose the opportunity to get the maximum profit so do the opposite. By using this application it is expected the company could provide convenience for the company to predict the amount of production based on the number of requests and the existing inventory data, in order to achieve optimal benefit

Analysis and Development of Marketing for the Creative Industry of West Sumatra Based on E-Commerce with the Concept of Customer Relationship Management (CRM)

West Sumatra is an area in Indonesia that has many Creative Industries, this is the reason the government places representatives of the Ministry of Creative Industries in this region. This is done to foster, oversee and develop the Creative Industries that exist today. The Creative Industries that exist today are very diverse there are 15 fields that are very potential to be developed in Indonesia, Advertising (Advertising), Architecture, Art Goods Market, Crafts (Craf), Design, Video, Film, Photography, Interactive Games (Games), Music , Performing Arts (Showbiz), Publishing and Printing, Computer and Software Services, Television and Radio (Broadcasting), Research and Development (R&D), Culinary. Of the 15 creative industries in Indonesia for the West Sumatra region there are 9 sub-sectors of potential creative industries, namely, fashion, culinary, handicraft, music, performing arts, photography, design, animation, and film, but not all creative industry sectors it is developing so that it has an impact on the marketing of its products. For this reason, it is necessary to analyze and develop the marketing of creative industries in West Sumatra that prioritizes the concept of Customer Relationship Management (CRM) so that marketing concepts that have the potential to increase marketing of creative industry products will be known. Especially now that the Provincial Government is developing the Halal Tourism Industry, of course in this field there are very many opportunities for the development of the Creative Industrie
