<![CDATA[Virtual Private Server is a private server whose entire resource is used by one user only and is not influenced by other users. The technology used by VPS is virtualization of physical server hardware which is then divided into several different resources. Called virtual because this division uses software so that in one physical server there are several VPS running. To be more extensive in terms of server control, researchers use Public IP and Dedicated IP as a distributor of VPS systems from local to public. In addition, in this VPS implementation, debian linux and ubuntu linux are used as operating systems to create a VPS server. To get the value of the VPS network performance test from the client using the parameters of the Quality of Service (QoS), namely Delay and Jitter. From the test results, the value of the VPS server resource obtained can be categorized as very good and feasible to be implemented with an average server CPU load of 2.9%, memory 71.23%, disk space 16.1%. And testing the QoS parameters (delay, jitter) also gets good performance and has a fairly low value obtained with an average delay value of 6-37.24%, jitter of 8.95-59.95%. ]]>

<![CDATA[Di era saat ini penjualan sayuran masih dilakukan dengan cara menjual ditempat seperti pondok sayur bahkan di lakukan dengan berkeliling dijalan atau di (jajak). Dengan adanya teknologi di zaman modern ini penulis melihat bahwa cara penjualan yang biasa dilakukan merupakan cara konvesional,penulis melihat ada kesempatan baik untuk membuat sistem yang akan memudahkan penjualan tersebut. Penjual sayuran merasa cara yang mereka gunakan saat ini sangat tidak efisien,terkadang sayuran yang mereka jual tidak habis,sayur layu dan banyak terbuang,cara pembayaran yang dilakukan juga masih menggunakan uang cash dan kembalian uang pelanggan biasanya dihitung menggunakan kalkulator,jika tidak ada uang kembalian maka uang tersebut di tukarkan kepada pedagang lainnya untuk mendapatkan uang pecahan. Hal tersebut menjadi motivasi bagi penulis untuk membuat sistem yang akan digunakan oleh penjual sayuran. Pemecahan masalah yang diterapkan adalah dengan membangun sistem penjualan sayur berbasis website. Sistem ini dapat memudahkan penjualan,memudahkan owner melihat perkembangan penjualan,sehingga transaksi penjualan dapat terkontrol dengan baik.]]>

Therefore, the data is analyzed in order tohelp recommend the layout of books and borrowers can find theappropriate books. To determine the suggestion of borrowedbooks, with the existence of play data can use the a priorialgorithm, a kind of association rule. The market basket analysismethod used by the a priori algorithm to establish associationsbetween various variables allows the system to further analyze andidentify trends related to borrowed books. Based on the results ofthe analysis that has been carried out, it is stated that this a priorialgorithm can be used to display recommendations betweenborrowed books. The support value can show the classification ofbooks borrowed simultaneously while the confidence value canfind out the recommendations for books borrowed.]]>
