Abstract

Customer segmentation is one approach used to identify customer characteristics. Accurate segmentation allows companies to personalize offers, increase customer retention and optimize marketing costs. The purpose of this study is to group customer characteristics of a retail company using the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) method. The DBSCAN method does not require initial determination of the number of clusters, is able to recognize clusters with irregular shapes and can identify outliers or customers with extreme patterns. The dataset used is an external dataset obtained from Kaggle. The dataset contains customer personalization analysis with a total of 2,240 rows and 29 columns. The results of the study show that the DBSCAN method can produce an eps value of 1.2 and produce the highest Silhouette Score of 0.080 with 4 clusters formed. Visualization of segmentation results with PCA dimension reduction techniques into two dimensions to facilitate interpretation. The PCA visualization produces 5 clusters, each of which represents its respective customer group. Thus, this approach offers an adaptive segmentation alternative that is more sensitive to complex behavioral patterns.Keywords : Customer segmentation, DBSCAN, shopping patterns, silhouette scorem, PCA

Abstract

Technology helps users do various things and activities that can produce the latest and innovative technology in various fields, including education. MTs Ma'arif Tembarak is a formal secondary level educational institution under the Ministry of Religion in Temanggung Regency. In carrying out archive management still using conventional methods and has not digitized archives, with 1,500 archive data recorded over 3 years. This causes uncertainty in archival documents and the history of follow-up to managed documents as well as difficulty in searching for data and documents. This research aims to design and build a web-based e-archive system for educational institutions to provide solutions to the problems faced. The method in this research uses the waterfall method with system visualization using DFD and ERD in the database management illustration used. The e-archive system was developed on a web basis with PHP and MySQL programming languages using the CodeIgniter framework and tested using the black box testing method with valid results. Next, a user evaluation was carried out on 5 respondents according to user level with the results of the feasibility percentage being 72%, based on the Likert scale, it was said that the impact or use value was good.

Abstract

Peribahasa Indonesia merupakan bagian tak terpisahkan dari warisan kebudayaan Indonesia yang telah mengakar dalam kehidupan sehari-hari masyarakat dari berbagai suku dan daerah. Dalam era globalisasi dan digitalisasi, terdapat kesenjangan antara kemajuan teknologi dan pelestarian budaya akibatnya pemahaman terhadap peribahasa Indonesia semakin menurun di kalangan masyarakat, yang pada akhirnya dapat mengakibatkan terkikisnya warisan budaya bangsa. Salah satu solusi permasalahan adalah dengan pendekatan Pattern Matching berbasis Kata Kunci. Kata Kunci untuk mencari dan mencocokan kata-kata kunci tertentu yang ada di dalam peribahasa. Pattern Matching memiliki kemampuan mengidentifikasi pola leksikal spesifik, efisiensi dalam memetakan kata kunci ke makna kontekstual, fleksibilitas menangani variasi linguistic dan kesesuaian dengan karakteristik peribahasa yang memiliki kata kunci inti, kemudahan dalam merepresentasikan pengetahuan pakar ke dalam sistem digital. Tujuan penelitian ini adalah mengembangkan algoritma matching yaitu jaccard similarity untuk pencocokan kata kunci setiap peribahasa sehingga peribahsa dapat di interpretasi. Jaccard similarity memiliki tiga tahap, yaitu:input kata kunci, prepossessing dan pattern matching. Hasil penelitan ini dari 30 skenario dari empat kategori kata kunci, akurasi kecocokan kata kunci dengan kata kunci peribahasa 70%, sehingga interpreatsi peribahasa Indonesia dapat dihasilkan.Kata kunci: Sistem Pakar, Peribahasa, Interpretasi, PattrenMatching, Jaccard Similarity.
