Abstract

Information Technology Governance in UIN Jakarta is the responsibility of the Pusat Teknologi Informasi dan Pangkalan Data (Pustipanda). Some troubles have occurred in the data center Pustipanda, among others the loss of courses and its values that have been inputted in the application of Academic Information System (AIS), loss of data that has been inputted on the application Beban Kinerja Dosen (BKD), damage data content on the portal in the environment UIN Jakarta. Risk analysis is needed to identify and anticipate and minimize risks which may occur. In this research, the risk analysis is using the COBIT 4.1 framework that is in the PO9 process (Manage and Assess IT Risk) as input towards PO9 is the domain of PO1, PO10, DS2, DS4, DS5, ME1, and ME4. Questionnaires which were distributed to respondents were developed from input variables. Respondents were chosen by purposive sampling method. The results of the questionnaire were recapitulated and calculated the value and degree of capability. The result of this research is the level of domain capability in data center Pustipanda is at level 2 (managed) with value 1.91. A fairly low value is obtained on DS4, DS5 and ME1 domains, which are 1.67, 1.88 and 0.67. Arosen risks from the majority of data center risk assessment were the absence of documented policies and procedure and lack of training for risk management measures at Pustipanda data center.

Abstract

English Department of Tadulako University is a department with the highest number of lecturers in Tadulako University. Thesis supervisor determination at the English Department of Tadulako University still use the conventional way so that the determination of the thesis supervisor is done in a long time. In addition, some lecturers have more workload than other lecturers. Decision support system for the determination of the thesis supervisor in the English Department of Tadulako University was built to overcome this problem using the Weighted Product method. The system is a desktop-based application using the Visual Studio programming language and MySQL DBMS for database processing. The application of a decision support system for determining thesis supervisors can help make the selection of supervisors accurately and quickly with a mathematical calculation system.

Abstract

The Internet today has become a primary need for its users. According to market research company e-Marketer, there are 25 countries with the largest internet users in the world. Indonesia is in the sixth position with a total of 112.6 million internet users. With the increasing number of internet users are expected to help improve the economy and also education in a country. To be able to increase the number of internet users, especially in Indonesia, it is necessary to predict for the coming years so that the government can provide adequate facilities and pre-facilities in order to balance the growth of internet users and as a precautionary step when there is a decrease in the number of internet users. The data used in this study focus on data on the number of internet users in 25 countries in 2013-2017. The algorithm used is Artificial Neural Network Backpropagation. Data analysis was processed by Artificial Neural Network using Matlab R2011b (7.13). This study uses 5 architectural models. The best network architecture generated is 3-50-1 with an accuracy of 92% and the Mean Squared Error (MSE) is 0.00151674.

Abstract

Population data collection at the sub-district level still uses a manual system. It is causing less efficient time. In this study the application of population data is generated in the sub-district, using web applications and using the Unified Modeling Language design. With the above considerations, we need a system that can solve population data problems. With this application, it is expected that it will facilitate the processing of population data. This new application can accelerate the process of population registration with the help of human resources who can run it. Advice needed human resources that can run the application properly.

Abstract

Portable Document Format is a very powerful type of file to spread malware because it is needed by many people, this makes PDF malware not to be taken lightly. PDF files that have been embedded with malware can be Javascript, URL access, media that has been infected with malware, etc. With a variety of preventive measures can help to spread, for example in this study using the classification method between dangerous files or not. Two classification methods that have the highest accuracy value based on previous research are Support Vector Machine and Random Forest. There are 500 datasets consisting of 2 classes, namely malicious and not malicius and 21 malicius PDF features as material for the classification process. Based on the calculation of Confusion Matrix as a comparison of the results of the classification of the two methods, the results show that the Random Forest method has better results than Support Vector Machine even though its value is still not perfect.

Abstract

The technology that is currently developing is the use of QR-Code. QR-Code can convey information quickly with the acquisition of fast responses as well. QR-Code can be used on smartphones. Some media and companies widely use the QR-Code in Indonesia. QR-Code is not only used as an application identity but is also used as a means of effective, simple and modern business promotion. Making information systems for Sentra Ikan Bulak Surabaya is done by using QR-Code technology as a means of product promotion in the sales process. Research that has been done can run well and can support and be useful in improving the means of promotion. Traders find it easier to collect data on existing systems. Buyers can access the site and see reviews from other buyers so buyers will feel interested in buying the product.

Abstract

The capability level assesment for governance of the Election Organizer Ethics Court Information System [SIPEPP] is necessary to ensure strategic planning allignment, value delivery, risk management, resources management and performance measurement. SIPEPP implementation has special problems in optimizing human resources and weak supervision management, so it is important to asess capability levels to provide solutions to these problems. The purpose of this paper is to assess the current and expected capability level conditions, gap analysis and recommendations for SIPEPP good governance. This research method uses the Process Assessment Model (PAM) from Control Objectives for Information and Related Technology (COBIT 5) which consists of stages of initiation, planning the assessment, briefing, data collection, data validation, process attribute level, and result and recommendation. The results of this study indicate the level of optimization of resources and performance monitoring processes are level 2 (Managed Process) which means that the process has been recorded, measured and in accordance with the objectives. The process of managing human resources, assets and operations are at level 1 (Performed Process), meaning that both processes have been applied to SIPEPP governance. Recommendations related human resources are the selection of appropriate human resources by involving management, while related assets require a priority list of implementation systems, and related supervision requires detailed monitoring schedules. This study result can be taken into consideration for improving good governance of SIPEPP implementation.

Abstract

Arduino is one of the microcontroller devices commonly used on the Internet of Things. This research designed and objectified web-based data logging system that aimed to record communication and sensir data in iot devices, so it could monitor log data in iot. Devices from this data logging system was created using arduino uno r3 with adding ethernet shield modul and temperature sensor DHT 11. in iot devices, there is an important parameter, that is date time as a history in data logging sistem using an actual time. Website was functioned as system for showing data from log data and could be monitored realtime. This system could record communication brtween arduino device and NTP server using internet network. Beside that?this system could record important parameters in the system such as IP source address, ip destination address, ip address in each node, device time, and room temperature information. Parameters that had been recorded would be stored to database, then would be showed in web data logging.
