Abstract

 In 2023, Indonesia was again devastated by a hacker known as Bjorka. Bjorka did not act just once or twice; every time, Bjorka made the entire Indonesian population proud. The 19 million BPJS Employment data belonging to the Indonesian people that Bjorka hacked is the BPJS Employment data belonging to the Indonesian people that Bjorka hacked. Since the release of the Bjorka story, there has been a surge in the number of people criticizing it on social media, particularly Facebook, so the criticism or opinions can be used to conduct sentiment analysis. Based on this, developing a method that can automatically classify beliefs into positive and negative categories through sentiment analysis is necessary. The sentiment analysis process begins with data preprocessing, followed by keyword analysis using the TF-IDF method, algorithm development, and analysis of classification results. The data classification methods used in this study are Naive Bayes and C4.5. The data will be analyzed using text mining and classified using the Naive Bayes and C4.5 algorithms. Based on the results of the tests, the best classification was achieved by Nave Bayes, with a score of 70 percent for the C4.5 algorithm and 68 percent for the C4.5 algorithm. The Nave Bayes algorithm can predict up to 70% data transmission rates for both positive and negative signals.

Abstract

Penelitian ini bertujuan untuk merancang dan mengimplementasikan Sistem Pendukung Keputusan (SPK) dalam proses seleksi karyawan terbaik di PT. XYZ menggunakan algoritma Random Forest. Permasalahan utama yang dihadapi perusahaan adalah proses penilaian karyawan yang masih dilakukan secara manual melalui Microsoft Excel, sehingga rawan terhadap kesalahan perhitungan, duplikasi data, serta memerlukan waktu yang lama untuk menentukan karyawan berprestasi. Untuk mengatasi hal tersebut, penelitian ini mengusulkan penerapan sistem berbasis web yang terintegrasi dengan model klasifikasi machine learning guna meningkatkan efisiensi dan objektivitas proses evaluasi. Metode penelitian yang digunakan meliputi tiga tahap pengumpulan data, yaitu studi pustaka, observasi, dan wawancara. Proses pengembangan sistem dilakukan menggunakan model Software Development Life Cycle (SDLC) dengan pendekatan Waterfall, yang mencakup tahapan perencanaan, analisis kebutuhan, perancangan sistem, implementasi, pengujian, dan pemeliharaan. Hasil implementasi menunjukkan bahwa sistem mampu menampilkan hasil penilaian karyawan berdasarkan empat kriteria utama: kedisiplinan, kinerja, sikap kerja, dan keahlian, yang kemudian diolah menggunakan algoritma Random Forest untuk menentukan peringkat akhir. Hasil pengujian menunjukkan bahwa penerapan metode Random Forest memberikan tingkat akurasi yang tinggi dalam proses klasifikasi dengan nilai akurasi mencapai 91,2%, serta menghasilkan peringkat karyawan yang konsisten dengan hasil evaluasi HRD. Sistem ini juga dilengkapi dengan antarmuka pengguna yang sederhana dan informatif, yang memudahkan admin, HRD, dan karyawan dalam mengakses informasi sesuai hak akses masing-masing. Secara keseluruhan, penerapan algoritma Random Forest dalam sistem pendukung keputusan ini terbukti efektif dalam meningkatkan kecepatan, objektivitas, dan transparansi proses penilaian karyawan di PT. XYZ.

Abstract

transformation in various sectors, including the fashion industry, especially sneakers. Sneakers are now a symbol of modern lifestyle and global trends, with brands such as Nike and Adidas dominating the market. However, high prices are an obstacle for many Indonesian consumers. This opens up opportunities for local brands to offer quality products at affordable prices through e-commerce such as Tokopedia, the second highest traffic platform in Indonesia. The research analyzed sentiment from 1,032 consumer reviews of local sneakers from five stores: NAH Project, Aerostreet, Geoff Max, Ventela, and Brodo. The analysis was conducted using Naïve Bayes and Support Vector Machine (SVM) algorithms. The SVM evaluation results produced the highest accuracy of 98%, compared to Naïve Bayes which reached 96%. This best model is implemented in a web-based application to analyze the sentiment of new reviews, to assess the perceived quality and consumer satisfaction of local sneakers products on Tokopedia.

Abstract

The rapid development of information technology encourages educational institutions to improve efficiency and security in administrative management, including payroll systems. This research aims to design a web-based E-Payroll system implemented at the Islamic Education Foundation An-Nadwah by applying the Advanced Encryption Standard (AES) algorithm to ensure the confidentiality of employee salary data. The system was developed using the Rapid Application Development (RAD) method to enable fast and user-responsive development. The implementation results show that the system can effectively encrypt and decrypt salary data, as well as provide real-time and secure payroll reports. System testing using the blackbox method demonstrates that all system functionalities work as expected. This system is expected to enhance efficiency, accuracy, and security in the payroll process within the foundation.
