Development of a Spatial Path-Analysis Method for Spatial Data Analysis Wiwin Sulistyo; Subanar Subanar; Reza Pulungan
International Journal of Electrical and Computer Engineering (IJECE) Vol 8, No 4: August 2018
Publisher : Institute of Advanced Engineering and Science

Path analysis is a method used to analyze the relationship between independent and dependent variables to identify direct and indirect relationship between them. This method is developed by Sewal Wright and initially only uses correlation analysis results in identifying the variables' relationship. Path analysis method currently is mostly used to deal with variables with non-spatial data type. When analyzing variables that have elements of spatial dependency, path analysis could result in a less precise model. Therefore, it is necessary to build a path analysis model that is able to identify and take into account the effects of spatial dependencies. Spatial autocorrelation and spatial regression methods can be used to develop path analysis method so as to identify the effects of spatial dependencies. This paper proposes a method in the form of path analysis method development to process data that have spatial elements. This study also discusses our effort on establishing a method that could be used to identify and analyze the spatial effect on data in the framework of path analysis; we call this method spatial path analysis.

Wireless Distribution System allows for creating a wireless network without using a wired network backbone. Wireless network using WDS technology associated by create a link on some wireless access point that is called WDS links. The advantage by using WDS technology is to integrate all access points in a single wireless network. Wireless distribution system can handle the complexity of the cable instalation, where physically impossible to pull the cable as a backbone network. Wireless network using WDS technology has the mobility and high reliability. However, not all access points support WDS technology. Access points that use indoor access point that is WRT54GL which does not have WDS feature, because the standard firmware of access points it is still very less features. This problem can be solved by installing DD-WRT firmware into access point. after performing a firmware upgrade, the capability of the access points increase and has full features such as WDS feature.

Faculty of Information Technology has a server in each laboratory which has different file stored and located in different location. Storage system in Faculty of Information Technology Satya Wacana Christian University labs has a problem, that is needed file sharing that is used on laboratory which had different location for class purposes. The problem would be happened that caused long distance and take much time just to get a file for learning in class. Cloud computing system designed for that problem, with using proxmox as a virtual manager and EyeOS as cloudmanagement, this system would solve the data centralization problem because all of laboratory files and documents for class activity would be placed into one cloud storage and able to accessed with any communication media tools. Cloud has a SSL encryption security system so that file which located on cloud would be secured because it was encrypted. Final result from this research would obtain a cloud server which used as centralized storage places and accessible for global or local purposes.

The Intrusion Prevention System (IPS) Snort is a server security System that can prevent attacks by examining and recording all data packets as well as recognizing packets with sensors, when the attack has been identified, IPS Snort will deny the access (block) and log of all data packets identified. However by using only IPS Snort which can only check and note the Allert attacks that are incoming in less sense to secure a server by collaborating with the other server's secure system in the sense of being able to make the network security of the server better. Honeypot Artillery chosen which works when there is a Hacker trying to penetrate through open ports can be detected as if hackers can break through the system, then Honeypot Artillery will provide information about who attackers and how the attacker could enter the Snort IPS system for later record in the database that can be viewed on the Web interface, Allert recorded on the experiment that has been done in the database as much as 9453 on TCP protocol as much as 9%, UDP as much as < 1%, and ICMP As much as 91%.

The notification system for two-wheeled motorcycles is currently very ineffective, so that the theft of motorcycles is very high if they still use an alarm without notification to the owner of the motor vehicle. So that the motorcycle notification system using a GSM module based on a microcontroller can be an alternative to secure motorcycles from theft. The purpose of this study is to make a notification system using the GSM SIM800L module to provide notifications and use an RFID Reader to replace the contact system on a motorcycle. The test results from this study are the performance of the notification system using a GSM module based on this microcontroller can work well. When the RFID receives input from the e-KTP ID Tag and is forwarded to the microcontroller and forwarded to the SIM800L to send an SMS notification, the microcontroller will give the output to the relay to turn on the electricity on the motorcycle.
