<![CDATA[The increasing number of internet users in Indonesia has an impact on increasing the number of users of streaming video. The increase in the number of users is based on technological developments with the emergence of mobile devices such as notebooks, tablets and smartphones equipped with internet access via wireless networks. Unlike networks using cables, the characteristics of using video streaming over wireless networks are limited when compared to those using cables. To access various applications on the internet, including video streaming, a stable internet service is needed. For this reason, a Quality of Service (QoS) measurement research is needed which is carried out at one of the wireless network provider points in the city of Batam, namely Taman Internet Engku Putri. QoS can be used to measure and analyze the stability and quality of a wireless network. The parameters used in the measurement and analysis of QoS are Throughput, Delay, Jitter and Pakect Loss which will be tested on video streaming services. The test will be carried out at certain times such as peak hours and low hours. Low hours usually range from 08.00 WIB - 15.00 WIB and rush hour usually ranges from 15.00 WIB - 21.00 WIB. The results of measurement and analysis using four QoS parameters show that the video streaming service using wireless networks in Taman Internet Engku Putri is in the medium category.]]>

<![CDATA[PT Sumber Alfaria Trijaya Tbk atau yang lebih dikenal dengan Alfamart merupakan salah satu perusahaan yang bergerak dibidang ritel yang mana perusahaan ini setiap harinya harus memenuhi kebutuhan konsumen. Selain itu, peletakan produk pada rak yang tidak sesuai dengan kebiasaan konsumen saat membeli produk secara bersamaan dalam satu waktu. Hal ini menyebabkan kekecewaan pada konsumen yang tidak dapat memenuhi kebutuhannya. Maka dari itu perusahaan harus mencermati pola pembelian yang dilakukan oleh konsumen. Untuk mengetahui produk yang dibeli secara bersamaan, menggunakan association rule (aturan asosiasi) yaitu teknik Data Mining untuk menemukan aturan asosiasi suatu kombinasi item. Proses pencarian asosiasi menggunakan metode algoritma C4.5 yang dapat menghasilkan pengetahuan yang terkandung dalam data transaksi pelanggan, mengenai pola pembelian oleh konsumen. Berdasarkan hasil perhitungan algoritma C4.5 yang memenuhi syarat nilai minimum confidence dan diuji dengan software Tanagra, pada toko Alfamart rule tertinggi yang muncul pada produk Kunci Mas Minyak Goreng Pch 1,8l dan Sedap Mie Kari Special 75G dengan nilai Support 43,3% dan confidence 92,8%, hal ini sama dengan perhitungan manual algoritma C4.5. Maka dapat dilakukan pengaturan tata letak produk secara berdekatan untuk memudahkan keberadaan produk tersebut dan memudahkan dalam menentukan persediaan produk promo yang diinginkan konsumen serta dapat digunakan sebagai pendukung keputusan manajer dalam mengelola aktifitas perusahaan.]]>

<![CDATA[Addressing mental health issues has become a priority for the Indonesian government due to the rising prevalence of depression and anxiety, especially in Riau Archipelago Province, which reported as one of the provinces with the highest suicide rates in the country. The World Health Organization has pointed out the deficiencies in data collection, reporting, and knowledge management related to mental health. PT XYZ has collected mental health data through annual medical check-ups utilizing the DASS-21 scale, but this data has not been analyzed to extract useful and actionable insights for management. This research aims to profile the mental health of PT XYZ workers using annual medical check-up data from June to September 2023, involving a total of 3,699 workers. By implementing the K-Means clustering algorithm based on three variables—depression, anxiety, and stress—the analysis revealed that 242 workers were identified in a cluster with severe mental health conditions, 1,271 in a cluster with moderate conditions, and the remaining 2,186 with mild conditions in a cluster.]]>
