An Intrusion Detection System (IDS) seeks to identify unauthorized access to computer systems’ resources and datausing a statistical approach. The scale on which a dataset variable is measured may not the most appropriate forstatistical analysis or describing variation, and may even hide the basic characteristics of the data. This paper proposed apre-processing analysis for detecting unusual observations that do not seem to belong to the pattern of variabilityproduced by the other observations. The pre-processing analysis consists of outliers detection and Transformation.Outliers are best detected visually whenever this is possible. Usually, the original data sets are not normally distributed.If normality is not a viable assumption, one alternative is to make non-normal data look normal. This paper explains thesteps for detecting outliers’ data and describes the Box-Cox power transformation method that transforms them tonormality. The transformation obtained by maximizing lamda functions usually improves the approximation tonormality.Keywords : IDS, dataset, outliers, transformation, pre-processing

Covid-19 is a global pandemic that has affected many jobs. Meetings that used to be held face-to-face are now being held online. The Riau Provincial Library and Archives Service (DIPERSIP) also implements online meetings, but this application is not supported by an adequate network configuration. This is evidenced by the results of the Quality of Services (QoS) measurement which get a poor score based on the TIPHON standard. To overcome this, a queue tree is applied to the DIPERSIP router to manage bandwidth usage. Configuration begins with creating static and dynamic address lists for conference meetings. Then create a mangle to mark connections and packets that are useful for the queue tree, and end with the creation of a queue tree to limit every activity related to upload-download. This configuration has proven to be effective in overcoming existing problems, as evidenced by the QoS re-measurement results that get very good scores.Keywords: Address List, Bandwidth, Mangle, Quality of Services (QOS) Queue Tree.

Noken is the one of the variety handicraft in Indonesia from Papua. Noken is listed on UNESCO as an Indonesian culture heritage that must be preserved. Augmented Reality (AR) technology can beimplemented into an interactive application, so it can increase people attractiveness to know and to introduce Indonesian traditional handicrafts to the world. Commonly, AR application uses special marker so that application can be run (Marker Based Tracking). The use of these markers makes the application inflexible, because only certain marker which already uploaded by programmer on database system can be used. The research’s goal is to present noken in an application by showing3D object and video about noken on AR environment without using special marker. This application is created with Unity 3D and Vuforia by using Markerless User Defined Target (UDT). Moreover,some tools are also needed as supporting tools, like as Adobe Photoshop for interface designing, Adobe Premier for video editing, and Blender for creating noken 3D object. The final result of thisresearch is AR application for android with UDT technique which capable to show 3D object and video above real marker selected by user after detected by smartphone camera. The resultingapplication is alsoequipped with interactive features like scale and rotate. So this application can be used as alternative for conserving and spreading Papua handicraft in interesting and flexible way.Keywords :Augmented Reality (AR), User Defined Target (UDT), Android, Noken 3D object, video about noken

The development of internet technology is currently overgrowing, so the need for technological tools is increasing, one of which is the need for the internet. One easy way and much-loved by people is to use a wireless system/hotspot system. However, in using Wi-Fi network services in aplace with a limited bandwidth/speed, the user becomes wasteful both in terms of time and internet network usage. The purpose of this research is to design a Wi-Fi corner hotspot system using a proxy in a public place at the Otot IT store and make the voucher system key access to the internet network. This research was carried out in the Otot IT shop environment on JalanRaya Pekanbaru-Bangkinang KM43, Koto Tibun village. The stages carried out in this study began with problem identification, literature study, identification of system requirements, system design, and system testing. The RB 941-2nD (hAP Lite) router will be the primary device in creating a Wi-Fi corner hotspot. The voucher system is made using the Mikhmon application.Testing the internet connection quality can be seen using the PING, download, andupload parameters. In this study, the data analysis technique used is qualitative analysis with the Quality of Service (QoS) method. This study shows that users who want to use internet service access must have a voucher first, different from before where users only ask for a Wi-Fi password and can repeatedly enter with the same password. If you do not have a voucher, youcan directly come to the store admin to buy it. With the voucher system, the network quality in the store will be able to be controlled and managed, such as limiting the sale of vouchers if users are using the internet a lot and avoiding repeated logins by users as before doing the voucher systemKeyword: Wi-Fi Corner, Hotspot, Mikrotik, Otot IT, & Voucher

To improve the optimization of the internet network, the Vocational High School (SMK) of FKIP UNRI uses the internet network using a wireless network so that all teachers, admin staff, and students can get data from the internet in real-time. SMK Labor has access points with different access point identification names, better known as SSID (Service Set Identifier). Of all the access point devices installed with different SSID names on each device, so that if the user changes buildings, they must reconnect to the SSID in the building. Device configuration is still done manually; therefore, network management impacts the access point management system. The network manager is required to configure the access point devices individually because there is no centralized access point management. To help this success, we need a technology that can manage a network centrally, making it easier to control all wireless access point devices in the network. One example of a wireless device that is often used is a Mikrotik router. Mikrotik has a function to manage a device centrally using the CAPsMAN feature, making it easier for admins to monitor all wireless access point devices contained in the network. With these problems, the author aims to design the management of access points by utilizing the CAPsMAN feature to make it easier for admins to manage and maintain the network at school.Keyword: Single SSID, CAPsMAN, Acess Point, Mikrotik
