Abstract

The design of balancing the load current on three-phase systems using a microcontroller ATMega 2560 is a tool that serves to reduce the power loss. Power loss due to the load current unbalance the current flows in the neutral phase on three-phase systems. Current flows in the neutral phase distribution transformer into a detriment to PT. PLN (Persero) for the power lost to the earth and can not be used by consumers. So that it will balanced the load current to reduce the value of neutral current. The tool is also equipped with a monitoring system that displays current magnitude of each phase including the neutral phase.The methods in making this tool is divided into two parts: first, the design of hardware consist of designing electronic components which are used by the current sensor circuits, relay, LCD (Liquid Crystal Display) etc. Second, the design of software is a tool listing program procedure including the monitoring program displays the current of each phase on LCD using the Arduino IDE. SCT013-030 current sensor used, the output of the current sensor is connected to the pin ADC (Analog to Digital Converter) microcontroller ATMega 2560. Then microcontroller process the data and generate a current value displayed on the LCD. The other result of processing current value is a command to enable or disable the relay that connects three-phase resource with single-phase loads.The result of the test design of balancing load current on three-phase system using a microcontroller ATMega 2560 succeed balancing the load current by moving the channel load of sequence number load the smallest connected to the phase with the current biggest load toward a phase that has a load current smallest when neutral current exceeds the limit is permitted. In this situation, the neutral current will not be possible be zero. In fact, the maximum current value for the neutral phase for PT. PLN (Persero) 50 amperes calibrated to 1 ampere and is used as a limit on this prototype. If the neutral current on LCD monitor exceeds 1 ampere, then there will be balancing of the load current. The current sensor measurement results are displayed on a monitoring approach measurement result using pliers ampere.

Abstract

XYZ International School redesign their IT System and Infrastructure to meet their target in implementing ICT based learning process. The implementation of new system and infrastructure have good impact in speed and accuracy of learning process but not yet evaluate in term of security matters. IT security audit perform to fulfill the evaluation need for security implemented in XYZ International School.  Audit perform based on CISSP common body of knowledge from (ISC)2 and concentrate in Access Control area. Result show that security concern already implemented and have a good standard in certain area like identification, authentication, authorization and implementation, but still need improvement in accountability and monitoring area

Abstract

College accreditation by BAN-PT is one of the parameters in determining the quality of universities in Indonesia. As consideration to achieve the standard from BAN-PT, so they have an evaluation process itself in study program or college to be meet the standard universities when set by the BAN-PT. In carrying out the process of self evaluation, required data source that is used as the basis in assessing on a criteria. In most of the study program, all data spread on the system information and physical document that different, that is require more time and effort to integrate up to interpret. Data warehouse fight important in collecting data that spread and become an information. The process data warehouse with ETL used to integrate, extract, clean, transforming and reload into the data warehouse. With the existence of the data warehouse on Academic STIMIK STIKOM Bali can make it easier for executives to get the information to support the standard accreditation standart three and can be used as a reference in decision making.
