Abstract

Employee attendance is a crucial factor in human resource management as it affects productivity and operational efficiency. However, the recording and analysis of employee attendance often encounter challenges, particularly in terms of the accuracy and effectiveness of the systems used. This study aims to develop an employee attendance classification model using the Gradient Boosted Trees algorithm to improve the accuracy of grouping attendance categories such as Present, Permission, Sick, Leave, and Absent into attendance level categories: High, Medium, and Low. The research method includes collecting employee attendance data throughout the year 2024. The model evaluation is carried out using metrics such as accuracy, precision, recall, and the confusion matrix. The results indicate that the developed model achieves an accuracy of 100.00%, with a mean precision of 100.00% and a mean recall of 100.00%.

Abstract

The digital printing industry in Indonesia is experiencing rapid growth thanks to the increasing demand from companies for printing services such as banners, stickers, brochures, and business cards. CV. Copy Paste is one of the companies operating in the digital printing industry that fulfills various printing orders every month. However, the company has difficulty identifying the most popular printing services, which makes it difficult to develop a targeted promotional strategy. In view of this problem, the aim of this study is to group digital printing services according to their popularity using the K-Means Clustering method. This study uses a quantitative approach, collecting sales data from the last 12 months, covering 160 types of services. The steps taken include preliminary data processing, namely attribute selection, data cleaning, and data transformation so that it can be effectively processed using the K-Means algorithm, implemented in the Python programming language. The test results show that digital printing services can be divided into three clusters: 115 less popular services (C1), 31 fairly popular services (C2), and 14 very popular services (C3). The results of this study provide information that can be used as a basis for strategic decisions regarding promotion and service management. In this way, the K-Means Clustering algorithm has proven effective in helping companies group products in a more objective and measurable way based on historical data.

Abstract

Pelayanan haji di Kementerian Haji dan Umrah Kota Sukabumi masih terkendala beberapa masalah, terutama dalam hal pelayanan informasi, transparansi proses pelayanan, serta belum tersedianya Aplikasi Web resmi yang mampu menyajikan data dan mempermudah pelayanan. Proses komunikasi yang terkendala harus datang langsung ke kantor dan dilakukan pada jam kantor saja, yang tentu bagi calon jemaah yang bekerja sebagai karyawan tentu merasa kesulitan, sehingga menimbulkan keterlambatan informasi dan potensi ketidakefisienan. penelitian ini bertujuan untuk memetakan kebutuhan arsitektur sistem informasi pelayanan haji dengan menggunakan Framework Zachman sebagian acuan analisis. Framework ini digunakan karena mampu memetakan kebutuhan dan memberikan gambaran menyeluruh dari berbagai perspektif, mulai dari perencanaan, kebutuhan bisnis, desain sistem, hingga model teknis. Sehingga metode seperti ini dapat membantu menyusun gambaran strategi pelayanan, proses, alur data, aktor hingga rancangan model informasi seperti Entity Relationship Diagram (ERD). Diharapkan melalui penelitian ini dapat menghasilkan sebuah arsitektur sistem Web yang dapat meningkatkan kualitas pelayanan publik, mempercepat akses layanan informasi haji dan memberikan efisiensi internal pada Kementerian Haji dan Umrah Kota Sukabumi. Dengan demikian mampu meningkatkan kepuasan dan kepercayaan masyarakat
