The ship escort mechanism and system in KRI / KAL in reporting the position of the ship beingguarded at this time is only limited to reports via radio communication equipment / HT. This causedthe KRI / KAL Commander's decision to be reconfirmed manually between the ship's escort Personneland the KRI / KAL Guard Officer. Therefore it is necessary to have a system that can monitor theposition of ship escort personnel periodically by applying LoRa (Long Range) technology integratedwith a GIS-based information system (Geographic Information System). The position monitoringsystem for ship escort personnel can send coordinate data from the Client transceiver device that iscarried by the ship escort personnel periodically with the 915MHz LoRa TM protocol and receive theclosest Gateway transceiver in KRI / KAL with the same frequency with an average time of two once asecond transmits, the coordinate data received is stored in the application server database monitoringthe position of ship escort personnel in the form of markers, so that the position of personnel ismonitored periodically and can be immediately reported to the KRI / KAL Commander as decisionmaker. This system can also receive coordinate data from several Client transceiver devices.Keywords: LoRa / GPS shield, ship personnel, GIS (Geographic Information System).

The purpose of this research is to design an attendance system using Global Positioning System (GPS) technology, as a useful solution. At PT. Cipta Anugrah Musi for the marketing staff to still be able to do attendance without using a fingerprint attendance machine. Based on the results of research and discussion on the marketing employee attendance monitoring system in the form of this android mobile, the following conclusions can be drawn. From the black box testing that has been done, it can be concluded that the employee attendance monitoring system can run well and there are no problems. GPS technology can provide information on where to take employee photos so that it is easy to find out the position of the employee's absence at that time to avoid cheating in attendance.

Floatover method has been proven a competitive installation technology in last thirty years. However, floatover installation is subject to a variety of technical challenges. Apart from weather restrictions, motions and position of the topside and deck transport vessel (DTV) should be strictly controlled during the entire installation operations. Therefore, a field monitoring system is essential to guarantee the installation safety. In this paper, a comprehensive introduction to the monitoring system developed by Shanghai Jiao Tong University is presented. The subsystems, including environment monitoring system, motions and position monitoring system, deck support units (DSUs) separating monitoring system, closed-circuit-television (CCTV) monitoring system as well as the integrated monitoring system (IMS), are proposed. Besides, the pre-installation surveys are also presented.
