Abstract

PT. XYZ merupakan salah satu marketplace terbesar di Indonesia sebagai penyedia layanan transaksi jual beli secara online.  Penelitian ini bertujuan untuk melakukan analisis sistem manajemen keamanan informasi yang diterapkan oleh PT. XYZ dalam ruang lingkup transaksi antara pelapak dan pelanggan menggunakan ISO/IEC 27001:2013 serta memberikan rekomendasi alur sistem manajemen keamanan informasi yang perlu diperbaiki. Perancangan model rekomendasi alur sistem manajemen keamanan informasi dijabarkan dengan menggunakan Data Flow Diagram. Penelitian ini menggunakan metode kualitatif deskriptif dengan teknik pengumpulan data triangulasi. Berdasarkan hasil penelitian dapat diketahui bahwa perusahaan tidak memenuhi kontrol ISO 27001:2013 pada kontrol Kriptografi (A.10). Selain itu perusahaan tidak memenuhi kontrol Organisasi Keamanan informasi (A.6) sebesar 21.4% dan Akusisi, Pengembangan, dan Peningkatan Sistem (A.14) sebesar 7.7%. Nilai Compliant terbesar yang dimiliki oleh sistem manajemen keamanan informasi perusahaan terdapat pada kontrol Keamanan Komunikasi (A.13) dan Aspek Keamanan Informasi pada Manajemen Keberlangsungan Bisnis (A.17) yaitu masing-masing memiliki nilai sebesar 100%. Dalam kontrol Kebijakan Keamanan Informasi (A.5), pemenuhan sistem keamanan informasi yang diterapkan oleh perusahaan hanya 50%. Pada kontrol Keamanan Sumber Daya Manusia (A.7) tingkat Compliant perusahaan terhadap persyaratan ISO 27001:2013 adalah sebesar 91.7% dan nilai Partially Compliant sebesar 8.3%. Pada kontrol Kontrol Akses (A.9) tingkat Compliant perusahaan terhadap persyaratan ISO 27001:2013 adalah sebesar 92.9% dan nilai Partially Compliant sebesar 7.1%. Rekomendasi Data Flow Diagram dibuat berdasarkan validasi hasil maturity level pada klausul A.10 yang memiliki nilai paling rendah, yaitu bernilai 1. Sehingga pemodelannya terdiri dari tiga entitas yaitu: Pemilik Akun, Database Engineer, dan DPPED. Selain itu, terdapat empat data store yaitu: Kebijakan Penggunaan Kendali Kriptografi, Manajemen Kunci, Data Center, dan Dashboard Big Data Platform. Proses tersebut dirinci hingga level 2 yang terfokus pada proses enkripsi.

Abstract

Indonesia?s coal mining industry has been decreased since the last five years and causing the financial performance of companies in the industry to deteriorate. The aim of this paper is to analyze the bankruptcy prediction on coal mining sector companies listed in Indonesia Stock Exchange (IDX) in 2012 ? 2016 using data mining prediction method that is artificial neural network model with three financial ratios as an input parameter. The financial ratios used are shareholder?s equity ratio, current ratio and return on assets. The results indicate that these ratios are very suitable to be used as an input parameter because it shows a quite significant difference in calculation results between bankrupted and non-bankrupted companies.The ANN training model used in the prediction process in this study resulted in the best training performance with the model architecture of 15 neurons on input layer and one hidden layer with 30 neurons in it. The training model produces training performance with the lowest MSE of 0,000000313 and the highest R of 99,9%. Bankruptcy prediction result using ANN showed that 7 (seven) coal mining sector companies are predicted to be bankrupt

Abstract

Based on statistical data, it is known that Android is the most popular smartphone with the largest number of users in the world, which is about 1.8 billion users. The high number of users also invite the many cases of information security and privacy caused by the lack of awareness of the user such as : spam, spoofing/phising, network incident, malware, uploading something personal data such as photos, phone numbers, addresses or having no antivirus. This study aims to find out about the awareness of the security of information and privacy of Android smartphone users by doing measurement of problem. The awareness has  some dimensions such as attitude, knowledge and behavior with the seven focus areas of information security namely trust in app repository, misconception about app testing, security and agreement message, pirated application, adoption Security control, spam sms and report of security incidents and three focus areas of privacy are perceived surveillance, perceived intrusion, secondary use of information. This research uses analytical hierarchy process (AHP) to measure the level of awareness of information security and privacy of smartphone users. Overall, the results of the research show that information security has an average level of awareness (71%) but the focus area of report for security incidents has a poor level of awareness (37%) this occur because users prefer to solve their own information security issues experienced and privacy has an average level of awareness (76%). However, for secondary use of information in attitude dimension has low awareness level (66%). Based on the results of this study, it can be concluded that smartphone users in Indonesia have a poor awareness level in maintaining security and privacy of their information.

Abstract

The importance of information and the possible risk of disruption, therefore the universities need to designed and implemented of the information security.  One of the standards that can be used to analyze the level of information security in the organization is ISO/IEC 27001 : 2013 and this standard has been prepared to provide requirements for establishing, implementing, maintaining and continually improving an information security management system. The objective of this research is to measure the level of information security based on standard ISO/IEC 27001: 2013 and modeling systems for information security management. This research uses descriptive qualitative approach, data collection and validation techniques with tringulasi (interview, observation and documentation). Data was analyzed using gap analysis and to measure the level of maturity this research uses SSE-CMM (Systems Security Engineering Capability Maturity Model). Based on the research results, Maturity level clause Information Security Policy reaches level 1 (Performed-Informally), clause Asset Management reaches level 3 (Well-Defined), clause Access Control reaches level 3 (Well-Defined), clause Physical and Environmental Security reaches level 3 (Well-Defined), clause Operational Security reaches level 3 (Well-Defined), Communication Security clause reaches the level 2 (Planned and Tracked). Based on the results of maturity level discovery of some weakness in asset management in implementing the policy. Therefore, the modeling system using the flow map and CD / DFD focused on Asset Management System.

Abstract

Information held by a company is one of the important factors for its success. Nowadays with rapid development of usage of internet and social media, bad information can also have a significantly negative impact on every element / level that exists in the company or in the community. Sometimes it can lead to public unrest. Bad or good information has correlation with the quality of information. The aim of this research  is to assest and analyze  the quality of information using Six Sigma approach and we choose Kaskus website as a case study. Kaskus is the largest community online in Indonesia. It provided various kinds of information to its user. By using its approach, this research consists of 5 stages, they are ?define?, ?measure?, ?analysis?, ?improve?, and ?control?. Each phase/stage using different tools to assess the current Information Quality, such as questionnaires for define phase, ?Expert Choice?(Analytic Hierarchy Process) for measure phase, and quality function deployment (QFD) for analysis stage. Questionnaires used for defining customer specifications and identify information quality problem, meanwhile software ?Expert Choice? used to measure the importance each quality information dimensions and then to validate/analyzise the problem of the data. And lastly, QFD used to determine the mutual relationships of information quality dimensions and critical to Information Quality factors. Output of ?Analyze? stage shows that Accuracy, Relevancy, and Objectivity dimension on Kaskus website need to be improved immediately because it reaches unacceptable point.
