Abstract

Role of tool’s in enterprise is important, because a machine cannot assembled if one of tool’s is not available. The problem that occured during transaction prosses of tools due to lack of information about the availability of tools, so the operator spend some time for searching the tools and the borrower is waiting for the operator. To solve this problem, a new system of tool’s crib is requied for the tools storage. This system uses web as tools availability and uses PLC instead of operator. PLC is connected to PC using ethernet cable and programmed with Visual Studio as master. But in communication between PLC and HMI cannot communicate because PLC and HMI is a differend vendor, therefore requied an application to connected them. OPC is solution for of communication between PLC and Visual Studio because OPC is special to connected different hardware and software vendor. This OPC called CX – Server Lite from Omron. The previous system is changed to automatic and called Automation Tool’s Crib and gives the fastest time than tools crib approximately 90 secondwith this communication.

Abstract

Businesses of any scale today cannot be separated from Information Systems and Technology, whether large or small scale requires a reliable information system to support appropriate, effective and efficient decision making for stakeholders. The information system that is currently trending in the business world is an Enterprise Resource Program (ERP) based on cloud computing (Cloud) which can help users run a business anywhere and anytime. In a report released by Delloite entitled: Hot Topics for IT Internal Audit In Financial Services reveals that the current hot issues are Cyber Security, Data Protection and Data Privacy, IT Governance and IT Risk. PT Petrokopindo is a company that has implemented cloud-based ERP. However, the potential for risks such as Cyber Security, Data Protection and Data Privacy from Cloud ERP can occur, which can disrupt the company's business operations. In this research, case studies will be carried out on companies that have implemented Cloud-ERP. The method used is the COBIT 5 Framework, which was chosen as the best and more complete guideline than other frameworks in the IT / IS management field (Sutikno, 2014). The expected result is to be able to identify security gaps and material weaknesses of the Cloud- ERP information system and then provide recommendations for improvements so that IS / IT becomes more reliable. It is hoped that this research can be useful for the development of IS / IT governance science, and as input for stakeholders on the Cloud-ERP platform in increasing the reliability of an IS / IT against the risk of information leakage and cyber attacks.
