Abstract

Lantikya Store Jombang merupakan salah satu toko retail di Kabupaten Jombang yang belum menerapkan strategi pemasaran yang memberikan pelayanan yang berbeda berdasarkan karakteristik dan tipe pelanggan. Segmentasi pelanggan adalah proses membagi pelanggan kedalam kelompok berdasarkan karakteristik atau perilaku yang berbeda untuk menunjukkan tingkat keragaman di antara pelanggan. Karakteristik dan perilaku pelanggan dilihat berdasarkan usia, pendapatan, rencency (terakhir melakukan transaksi), frequency (jumlah kedatangan), dan monetery (jumlah uang yang dikeluarkan) atau disebut dengan RFM (Rencency, Frequency, dan Monetery). Pengelompokkan dilakukan dengan salah satu algoritma yaitu K-Means dengan jumlah data yaitu 1140 data. Pada penelitian ini menghasilkan 4 kelompok berdasarkan perbandingan hasil dari metode pencarian kelompok yaitu elbow method, silhouette method, dan gap statistic. Analisis yang dilakukan untuk menyususun startegi pemasaran dihitung berdasarkan nilai variabel dengan metode Analytic Hierarchy Process (AHP) dan Customer Lifetime Value (CLV). Karakteristik dan tipe pelanggan yang dihasilkan dari 4 kelompok pelanggan yaitu usia generasi milenial yang memiliki pendapatan tinggi dengan tipe pelanggan untuk retensi umum dan pelanggan bernilai penting, serta usia generasi Z yang memiliki pendapatan rendah dengan tipe pelanggan untuk pengembangn umum dan pelanggan yang hilang.

Abstract

Social Networking Sites (SNS) have become integral communication platforms for knowledge sharing and professional connections. LinkedIn, a leading professional network, is widely utilized in today's digital era, primarily by professionals and the business community. This research focuses on analyzing user sentiment on LinkedIn through the application of the Support Vector Machine (SVM) and Naive Bayes methods. Understanding user opinions and satisfaction is important, and sentiment analysis serves as a key tool for this purpose. This study is a comparative analysis of Support Vector Machine (SVM) and Naïve Bayes algorithm for classifying user reviews of the LinkedIn application. Drawing on data from Google Play reviews, this research explores a range of user sentiment towards the LinkedIn platform, including positive, negative and neutral reviews. The application of SVM and Naive Bayes algorithms successfully classifies reviews into relevant sentiment categories. Analyzing 2000 review datasets with an 80% training and 20% testing data split, Support Vector Machines demonstrate an 80% accuracy rate, while Naïve Bayes achieves a 70% accuracy rate. The Support Vector Machines (SVM) algorithm has better accuracy than the Naïve Bayes algorithm based on the test scenarios that have been carried out.
