<![CDATA[Strengthening on Micro, Small and Medium Enterprises (MSMEs) in Indonesia needs to be supported by the use and good information systems management. Therefore, business actors are expected to be able to use a operational strategy supported by the use of information systems. Workshop is one of the complex MSMEs with integrated warehousing and financial reporting. The problem faced at this workshop UMKM is that there is no synchronization between the existing stock of goods and the sales stock, as well as reporting both warehouse reporting and financial reporting. For this reason, this study aims to build a web-based MSME information system for tire & rims workshops. In building this system, researchers used the agile software development method, namely SCRUM. This method is used because the system can adjust to the needs of the product owner, which is always changing and fast in processing. The results of this scrum stage, namely the product log, sprint backlog, sprint and working increment of the software, can resolve all problems that occur with regard to time, scope and cost issues so that in the implementation of making this system application can reduce the system requirements gap during the sprint process. So that the system can be completed in accordance with the requirements needed by the user. By using this workshop's UMKM information system, all sales operational activities can be monitored properly and sales and financial reports can be well structured.]]>

<![CDATA[Digital Forensics, a term that is increasingly popular with internet needs and increasing cybercrime activity. Cybercrime is a criminal activity with digital media as a tool for committing crimes. The process for uncovering cybercrime is called digital forensics. The initial stage in digital forensics is an acquisition. The acquisition phase is very important because it will affect the level of difficulty and ease in investigating cybercrime. Software acquisition will affect the abandoned artefacts and even overwrite important evidence by the software, therefore investigators must use the best software for the acquisition stage. This study shows the difference in software for the acquisition of the best Random Access Memory (RAM) such as processing time, memory usage, registry key, DLL. This research presents five acquisition software such as FTK Imager, Belkasoft RAM Capturer, Memoryze, DumpIt, Magnet RAM Capturer. Results of this study showed that FTK Imager left about 10 times more artefacts than DumpIt and Memoryze. Magnet RAM Capture the most artefacts, 4 times more than Belkasot RAM Capturer. Software acquisition with many artefacts, namely Capture RAM Magnet and FTK Imager, while for the fastest time is DumpIt and Capture RAM Magnet for software that takes a long time.]]>

<![CDATA[Kebutuhan Teknologi Informasi (TI) didalam institusi pendidikan menjadi kebutuhan yang sangat mutlak di saat ini. Kebutuhan Teknologi Informasi juga menjadi peranan penting untuk meningkatkan kinerja institusi pendidikan khususnya di Institut Teknologi Telkom Purwokerto (ITTP). Peranan IT Balanced Scorecard menjadi keunggulan tersendiri demi tercapainya visi misi ITTP sebagai kampus yang sangat mengedepankan TI baik itu di dalam kinerja manajemen dan pendidikan. Keunggulan IT Balanced Scorecard salah satunya adalah mendukung IT Governance, ini sangat diperlukan institusi untuk dapat menciptakan adanya sebuah keselarasan bisnis dan teknologi informasi demi mewujudkan continuous improvement ITTP. Permasalahan di ITTP saat ini dalam hal kegiatan perencanaan kinerja TI belum mengacu atau berpedoman ke sebuah standar tertentu. Kondisi yang terjadi sekarang adalah masing-masing unit/bagian merumuskan kebutuhan mereka secara subjektif dan tanpa pertimbangan khususnya di bagian IT Support. Penelitian ini bertujuan untuk merancang IT Balanced Scorecard yang nantinya akan digunakan untuk mengukur kinerja IT ITTP. Penelitian ini dimulai dengan menganalisa visi misi dan strategi yang didasarkan dari renstra ITTP dan menganalisis SWOT IT yang ada di ITTP untuk mengetahui kondisi saat ini. Kemudian penulis menganalisis matriks TOWS untuk mengetahui strategi dan KPI terbaik untuk ITTP kedepannya. Untuk membangun sasaran strategis dan strategy maps yang tepat, penulis mengacu kepada renstra ITTP agar terciptanya keselarasan bisnis dan IT. Langkah selanjutnya adalah dengan memetakan KPI hasil dari analisa matriks TOWS ke dalam sasaran strategi yang sudah dibentuk, sehingga IT Balanced Scorecard dapat terbentuk. Keobjektivitasan penelitian sangat mutlak diperlukan dalam membangun IT Balanced Scorecard sehingga penelitian pada studi kasus ini dapat menghasilkan 12 sasaran strategis dan menghasilkan 20 KPI yang akan digunakan sebagai ukuran kinerja IT Balanced Scorecard. Kata Kunci : IT Balanced Scorecard, IT Governance, SWOT, strategy maps]]>

<![CDATA[Information security is crucial and vital in digital era. Confidentiality and security of assets must be protected to minimize IT risks. An audit is needed to control whether the organization or agency has implemented information system security standards. One of the information system security audits that has an evaluation value of the level of readiness is to use the System Security Index (KAMI) based on ISO/27001 2013. KAMI is designed to assist organizations and institutions to conduct independent assessments and evaluate the level of readiness in implementing information security which includes the criteria for Governance, Risk Management, Framework, Asset Management, Information Security Technology, and Supplements. This study designed a system with an SDLC (System Development Life Cycle) approach consisting of Planning, Analysis, Design, and Implementation. The purpose of the development of the KAMI audit information system is to facilitate auditors and related parties in the audit process carried out using the KAMI Index based on ISO/IEC 27001:2013, so that auditors do not need to use Microsoft Excel again in the audit process. The results of this study are in the form of the KAMI Index information system website based on ISO/IEC 27001:2013. The conclusion from the blackbox testing results above is "Accepted", where the audit information system website based on ISO 27001:13 functions well and serves its users efficiently. There are no missing or incorrect functions, no errors in this test sign, value input test, document input test, and menu test. ]]>
