Abstract

Service in companies operating in the service system plays a very important role, including in one of the companies in the city of Palembang which we call Company XXX. The level of customer satisfaction with service at Company XXX needs to be considered in order to find out how satisfied customers are with the service system provided by Company XXX. On this occasion the researcher aims to analyze and predict the level of customer satisfaction at Company XXX using the C4.5 classification method. Customer satisfaction is an important factor in maintaining customer loyalty and improving company performance. Using historical customer data for the last 1 year, we apply the C4.5 algorithm to predict customer satisfaction levels. The research results show that the C4.5 method has quite high prediction accuracy, which reaches 83%. It is hoped that the findings from this research can help XXX Company identify the factors that influence customer satisfaction and be able to take strategic steps to improve the quality of service.

Abstract

Education about hardware and software is very important to improve technological literacy. This study discusses the introduction of hardware components such as CPU, RAM, motherboard, mouse, keyboard, hard disk, and software such as operating systems and applications. Interactive technology-based learning methods are used to facilitate understanding. This study uses a qualitative approach with a descriptive analysis method to describe the application of observation and question and answer methods as education for introducing hardware and software to early childhood. Data were collected through structured interviews, participatory observation and document analysis. Data obtained through observation and interviews were analyzed qualitatively. To test the validity of the data, data triangulation was used, namely comparing the findings of observations, interviews and document analysis. The results of the study showed that this approach significantly increased students' interest and knowledge in learning. Practice-based learning has proven to be the key to improving students' technological literacy. In addition, increasing technological literacy is expected to help students be better prepared to face challenges in the digital era.

Abstract

Penjualan merupakan faktor terpenting bagi seluruh perusahaan karena dengan adanya pnejualan, maka suatu perusahaan akan mendapat keuntungan yang lebih supaya bisa melanjutkan usaha tersebut. Prediksi atau peramalan penjualan (forecasting) adalah suatu perhitungan untuk meramalkan keadaan di masa mendatang melalui pengujian keadaan di masa lalu. Tujuan penelitian untuk memberikan usulan kepada perusahaan dalam menentukan stok barang berdasarkan prediksi data penjualan sebelumnya dengan menggunakan metode K-Nearest Neighbor (KNN). Berdarkan hasil penelitian yang telah dilakukan dapat diambil kesimpulan bahwa hasil dari perhitungan menggunakan algoritma KNN, didapatkan hasil prediksi penjualan produk berdasarkan nilai akurasi tertinggi dan terendah. Nilai akurasi tertinggi terhadap penjualan produk sebesar 97,3%. Sedangkan nilai akurasi terenda terhadap penjualan produk sebesar 86,5%. Dengan demikian metode algoritma KNN k=20 (97,3%) ini dapat diimplementasikan untuk memprediksi penjualan produk PT Bintang Sriwijaya Palembang.
