Interoperability Testing

Interoperability testing is widely recognized as a key to achieve seamless interoperability of smart grid applications, given the complex nature of modern power systems. In this work, the interoperability testing methodology proposed by the European Commission Joint Research Centre is applied to a specific use case in the context of smart grids. The selected use case examines a flexibility activation mechanism in a power grid system and includes DSO SCADA, Remote Terminal Unit and flexibility source, interacting to support a voltage regulation service. The adopted test bed consists of a real-time power grid simulator, a communication network emulator and use case actors’ models in a hardware-in-the-loop setup. The breakdown of the interoperability testing problem is accomplished by mapping the use case to the SGAM layers, specifying the Basic Application Profiles together with the Basic Application Interoperability Profiles (BAIOPs) and defining the design of experiments to carry out during the laboratory testing. Furthermore, the concepts of inter- and intra-BAIOP testing are formalized to reflect complementary interests of smart grid stakeholders. Experimental results prove the applicability of the methodology for testing the interoperability of large-scale and complex smart grid systems and reveal interesting features and possible pitfalls which should be considered when investigating the parameters responsible for the disruption of a system interoperability.

Tempat pelayanan kesehatan bertujuan untuk memberikan pelayanan kesehatan kepada masyarakat melalui lembaga institusi pelayanan kesehatan. Masyarakat di Kota Palembang mendapatkan informasi tempat pelayanan kesehatan melalui informasi masyarakat sekitar, lembaga pelayanan kesehatan dan beberapa situs internet yang ditampilkan secara terpisah. Maka sebuah website geografis diperlukan untuk menampilkan tata letak lokasi pelayanan kesehatan dan informasi lengkap tentang pelayanan kesehatan di Kota Palembang. Penelitian ini bertujuan untuk membuat sebuah pemodelan website geografis tempat pelayanan kesehatan di Kota Palembang. Pemodelan yang digunakan berbasis object oriented dengan menerapkan use case diagram dan activity diagram.

Use Case Diagram

Inventory adalah aktiva yang meliputi barang-barang milik perusahaan, instansi, bidang pendidikan dan lain-lain. PT Anugrah Distributor Indonesia merupakan instansi milik perusahaan teknologi informasi yang didalamnya terdapat bagian logistik. Logistik berfungsi untuk mengelola kegiatan transaksi pembelian dan pengeluaran barang. Pengelolaan tersebut masih memanfaatkan Ms Excel. Sistem ini memakan waktu lama dalam proses pengelolaan data dan tingkat keakuratannya belum maksimal. Untuk memperoleh keakuratan data, logistik membutuhkan suatu sistem yang efisien, efektif dan valid dalam mengelola kegiatan transaksi pembelian dan pengeluaran barang. Dengan demikian dalam penelitian ini peneliti melakukan pengembangan sistem logistik yang saling terintegrasi menggunakan Unified Modelling Language (UML) yang digambarkan dengan Use Case Diagram, Activity Diagram, Sequence Diagram dan Class Diagram dan menggunakan bahasa pemprogramman PHP (Hypertext Preprocessor). Hasil akhir dari penelitian ini adalah sistem informasi inventory stok barang yang sesuai dengan kebutuhan dan memudahkan user dalam menginput dan membuat laporan persediaan barang. Sistem ini dibuat agar proses inventory dapat terkendali dengan baik, menjadi efektif dan efisien. Kata kunci: Sistem inventory, UML, PHP, Sistem Informasi

Information sharing has become prevalent due to the expansion of social networking in this 21st century. However, electronic devices are vulnerable to various kinds of attacks. Information might be disclosed, modified and accessed by an unauthorised third party which consequently leads to the breach of confidentiality, integrity and availability of the information. Therefore, it is of utmost importance to employ the technology of cryptography and steganography to protect information assets. Cryptography and steganography have weaknesses when they are working alone. Therefore, crypto-steganography, the combination of cryptography and steganography are introduced to overcome the weaknesses in order to provide a double layer of security and protection. This paper provides a general overview of steganography and cryptography as well as a comparison analysis of different crypto-steganographic schemes. A secure crypto-steganographic system for healthcare is then developed with the implementation and integration of the secure crypto-steganographic scheme proposed by Juneja and Sandhu. This healthcare system enables users to store and deliver message in a more secure way while achieving the main goals of both cryptography and steganography.
