Abstract

Ibu Ipung kitchen is a home industry that is engaged in making donuts located in Perum Cikarang Permai housing. Not only Bu Ipung's Kitchen, there are still quite a few other businessmen who are engaged in similar fields. This research is expected to be useful to help consumers see the products that are not selling well, selling well, and selling very well in the sales of Dapur Bu Ipung. The data collected from 2016-2021 is 570 sales transaction data. The purpose of this study is to group sales data into a cluster using the K-Means Clustering Algorithm Data Mining method. Sales data are grouped based on the similarity of the data so that data with the same characteristics will be in one cluster. So that it can be grouped using the K-Means algorithm into several criteria that are very good, sellable and less well-sold. The cluster that is formed after the K-Means Clustering process is carried out is divided into 3 Clusters Cluster 0 with 9 members with a percentage of 64.28% categorized as Less Selling, Cluster 1 number of members 1 with a percentage of 7.14% is categorized as very popular, and Cluster 2 with a percentage of 4 members with a percentage of 27.57% is categorized as popular, from the clustering process above, DBI validation (Davies Bouldin Index) can be obtained with a value of 0.451.

Abstract

The availability of sales data at the Ayam Penyet Nabila outlet is not used as much as possible, so that the sales data is not utilized maximally to find out what foods are most preferred by consumers or best-selling. The purpose of this research is to apply the C4.5 Algorithm method at the Penyet Nabila Chicken outlet and hopefully it can produce a knowledge in the form of a classification of food sales which is most preferred by many customers from existing datasets (in demand and in demand). The method used to classify food sales is C4.5 Algorithm, the process uses the five-step rule in KDD (Knowledge Discovery in Databases), which includes several activities namely selection, preprocessing, transformation, data mining, interpretation and evaluation. Besides making calculations in the form of a manual, I also tested this research using the RapidMiner tool. From the research output looking for decision tree results using the C4.5 Algorithm method the entrophy value is generated and for the highest gain value is 0.463363648 on the Sold Amount attribute in manual calculations. Whereas using the RapidMiner tool generated a decision tree as shown in Figure 4.3 Amount Sold - Price - Menu Name. The results of this study are the best-selling sales of Penyet Chicken, Grilled Chicken, Serundeng Chicken. Research using the C4.5 Algorithm method with the RapidMiner tool has an accuracy value of 86.40%, precision 86.29%, recall of 90.53%.

Abstract

Presence is crucial in a government institution. With an effective attendance system, it is hoped that it can assist in controlling the task completion process. The Attendance Recording System used in the Public Section applies fingerprint technology. Fingerprint is one of the information technology innovations that makes it easier to record employee activities every day. At this time employees do not take attendance using a fingerprint machine and return to using a manual system. The system is done manually, namely by signing the attendance book that has been provided by the staffing department. The purpose of developing this application is to facilitate, and speed up, employees in taking attendance and managing attendance outside the office. The method used in developing web-based non-ASN attendance applications is the waterfall model. as a structured software approach, starting from the stages of analysis, design, coding, testing, to the support stage. The PHP programming language, Laravel Framework and Database Management System (DBMS) use MySQL. The result of this research is the development of a web-based non-asn attendance application for non-asn employees in the general section of the regional secretariat of Bekasi district
