Abstract

Currently the rapid development of technology provides innovation, one of which is the technique of obtaining information from portal websites, termed web scrapers. This application provides data needs in the form of information where the process of retrieving information from sites will later be taken to observe behavior and perceptions to get the right segmentation. Most data collection is currently still done manually, as a result, this method has several system limitations, namely the length of the data collection process so that it slows down the performance of market segment analysis. The risk is not getting the right market segmentation. To solve this problem, a web scraping news site is needed. In this study, web scraping news sites were created using the python programming language and the flask library to display web scraping. In addition, the Selenium library is used to simplify application creation, facilitate interaction with the web and provide facilities to control a web browser. This program can retrieve data based on keywords, where the results are in the form of the title, posting date, summary, then collect the data that has been taken into a csv file extension automatically.

Abstract

Currently, technology can affect services in any field, both in areas such as salon services and sales of clothing products. How to plan a marketing strategy using the web based on service transaction data and products that are most often chosen by customers. Therefore, an information system for determining frequency patterns is needed using the website-based Apriori Algorithm method. The results of research on salons based on the type of beauty treatment obtained for the type of treatment with a minimum confidence = 70%, the first confidence value is 63% if the customer chooses to wash (shampoo), the customer chooses scissors, the second the confidence value is 100%, if the customer chooses to blow then chooses also cut, and the third confidence value is 86% if the customer chooses creambath then the customer chooses to cut too. Meanwhile at the shop clothes determining the frequency pattern of types of clothes with a minimum value of confidence = 70% so that the results include if a customer buys a veil, the customer buys a robe with a confidence value of 71.43% and if a customer buys khimar then the customer will also buy a robe with a confidence value of 78, 57%.

Abstract

Changes in land use and cover of an area significantly affect the quality of the area, especially from a socio-economic perspective. If city and regional governments are unable to anticipate these changes, it can greatly impact the security of the area, such as a lack of availability of public facilities, increased crime, and other social aspects. Research on changes in land use and cover has mostly focused on agriculture and rarely addresses regional security. Therefore, this study focuses on changes in land use, particularly in the type of urban residential land use in Bekasi city. The data used are Landsat satellite images from two different years for the Bekasi city area, utilizing trend change analysis with the Idrisi Selva application. Initially, a land cover classification process was carried out using the Iterative Self-Organizing Clustering (ISOCLUST) method, followed by reclassification with the same application into five classes: agriculture, vacant land, buildings, vegetation, and water bodies. The results show the direction of land change development where residential areas increase in the direction according to the degree of trend change, namely to the lower middle for the third degree and to the northwest and lower middle for the fifth degree. The research results can be used by regional planners in creating Spatial and Regional Plans (RTRW) as well as Detailed Spatial Plans (RDTR).

Abstract

ABSTRACTAside forecasting, classification is an important process in the data mining field. Nowdays, theclassification usually use soft computing algorithms, such as Fuzzy Inference System (FIS), NeuralNetworks (NNs), and Genetic Algorithms (GAs). Different from K-Means, the fuzzy-based classification issometimes is said soft clustering. Some dynamic method has been research using K-Means for obtaining theoptimal number of cluster. This paper try to implement this method for FCM algoritms because thisalgorithms run better than K-Means. Similar to Dynamic Clustering using K-Means, for FCM everyelements of cluster are counted the distance from the center. Key Workds : Fuzzy C-Means Clustering (FCM), Cluster Quality, Dynamic Classification ABSTRAKSelain peramalan, klasifikasi merupakan salah satu proses penting dalam bidang data mining. Saat iniklasifikasi banyak dilakukan dengan algoritma-algoritma yang berbasis soft computing seperti fuzzy,jaringan syaraf tiruan (JST) ataupun algoritma genetik. Berbeda dengan K-Means, klasifikasi berbasis fuzzyyang sering disebut fuzzy C-Means (FCM) merupakan klasifikasi halus (soft clustering). Beberapa metodedinamis dengan memodifikasi algoritma K-Means telah banyak dilakukan dan terbukti memiliki hasil yangoptimal. Tulisan ini bermaksud menerapkan metode dinamis itu pada algoritma FCM mengingat FCMmemiliki keunggulan tertentu dibanding K-Means. Seperti pada K-Means, klasifikasi dinamis pada FCMmenunjukkan perbaikan pada nilai intra dan inter dimana nilai-nilai tersebut menunjukkan kedekatan antarelemen tiap kluster dan seberapa jauh jarak pisah antar pusat-pusat kluster. Kata Kunci : Fuzzy C-Means Clustering (FCM), Kualitas Kluster, Klasifikasi Dinamis

Abstract

Bekasi Regency is a buffer area for Jakarta and is part of the Jakarta Metropolitan Region (JMR). Along with Karawang, this region is a major rice producer, but it is currently experiencing significant land conversion from agriculture to residential and industrial uses. Preventing this conversion is very challenging due to the high population growth in the area. To address this issue, this study aims to conduct a suitability analysis to identify areas that are unsuitable for agricultural land but still suitable for residential purposes. The factors considered in the suitability analysis include slope, distance to roads, distance to residential areas, distance to facilities and infrastructure, and distance to rivers and irrigation systems. The results of the study identify areas that are unsuitable for agriculture, allowing local governments to focus on these areas as potential sites for new residential developments. The location is situated in the southern part of Bekasi Regency, specifically in the Cikarang area and its surroundings.

Abstract

Most web-based applications are applications that provide services to users. The services themselves often change according to policies that are usually based on user satisfaction information. Unfortunately, existing applications are mostly based on open-source which is mostly monolithic. If there is an addition of a new service, it requires development from the beginning again. Especially when there is an imbalance between one service and another where one service requires large resources while other services do not require too many resources such as processors, network speed, or database size. This study tries to propose a system change in the library based on PHP-MySQL to be based on microservices.
