Abstract

PT. X is a company engaged in the pallet industry, such as the production of wooden pallets, plastic pallets distribution, ISPM#15 services, and the services of container checkers. Until now, not all business processes are being supported by information systems because there are many business processes being done manually and the existing information systems are not yet integrated. Existing information systems in the company only supports finance and accounting process. Based on this condition, this thesis will analyze and construct enterprise architecture design for PT. X using Enterprise Architecture Planning method. The first stage will be done with business modeling and analysis of business strategy company. After that, the next step is to see the condition of the companys information technology at the moment, the existing problems within the company, and information technology needs in the future. Then from these, the results will be constructed by making design data architecture, application architecture, and technology architecture. Data architecture generates multiple subsystems at the company, such as sub-system of sales, sub-system of purchase, sub-system of production, sub-system of ISPM # 15, sub-system of container checker, sub-system of IT, sub-system HRD, and sub-system of finance and accounting.

Abstract

The development and growth of Hospital X is getting bigger and bigger, and has information system in running their operational activities. Hospital X itself has a server to support its activities, especially the administration system which contains data about their patients. With the availability of the network at the Hospital X, either through Wi-Fi or an Ethernet cable, therefore it should be noted the bonds between networks and servers. Furthermore it is an important need nowadays to help minimize and anticipate the hacking crimes of the existing servers. One of the things that can be done is to monitor the administration and conduct vulnerability testing.Based on the background of the problem, it is necessary to evaluate server and network security using the vulnerability / penetration testing. In addition, this study also uses the guidelines of the CEH (Certified Ethical Hacker), Acunetix, and CISSP (Certified Information Systems Security Professional) modules. The testing of this thesis aims to find weaknesses in the administration system at Hospital X. Some problems were discovered after testing, which each of the weaknesses has different handling or treatment, physical security server weak, and unused opened ports that should not be open.The solution offered to solve these problems, are: the use of Acunetix and CISSP as a standard network security as the solution to anticipate weaknesses, to perform maintenance on a regular basis for the hardware, software, and network, to filter the existing port, to increase the level of security of the server, and to test security regularly and periodically, either through consultation with the related field experts or using a guide (like Acunetix, CEH, and CISSP).

Abstract

Based on the data of Polda Metro Jaya, theft of four-wheel motor vehicles experienced the highest increase which is 17 percent in 2015. Nowadays, the perpetrators are increasingly skilled in running a car theft. Despite having a car alarm for security system, it has limited distances. It leads to many unexpected ways for the perpetrators to damage on the car security system.It is certainly dangerous if the car owner left the car in a long distance without monitoring. In addition, the owner of the car will be aggrieved. Hence, it is necessary to build a technology that can help car owners to monitor the vehicle remotely. Regarding the problem above, an application that can help car owners to check their vehicles anywhere is required.Security Camera application uses Android and Raspberry Pi. This application is able to detect the movement of the camera in which is connected with the Raspberry Pi. In addition, the users can view an in-car live streaming. Moreover, the users will get notifications on their android devices and email as well as get an access to images and videos in which is detected in the camera.

Abstract

Teaching and learning process are growing over time and technology behind it are growing too so that the process of learning with online media or often referred to as e-learning where provided media that can be accessed via the internet. This phenomenon is interesting to examine because some e-learning systems that exist today are not yet fully secure, in the sense that it is still easy to be disseminated without any copyright and not used wisely. The purpose of this research is to produce an application that can be used as a media for e-learning of streaming audio and video without storing the file on local cache device so that the file residing in e-learning media cannot be disseminated and be used wisely. As a research methodology using deductive qualitative method, data collective process is done by literature study, interview, and observation. After the data collected, will result e-learning software based on website and mobile that can be used to stream media files without downloading it. The result of this test and analyze shown that streaming with RTSP protocol is can be used into e-learning software with a limited users.

Abstract

The main foundation of information system is database and programming. Inefficient database and unstructured programming can influence information system performance. Database design is very important, including the data design, data domain and relationship. Unstable design can cause data lost, inconsistent data, redundancy data, slow data updating and many more. A some presented in this paper study cases here show how important the step of design before the step of making database, which is called the design of logical data model. From these study cases here, we can see that design will influence the database. Abstract in Bahasa Indonesia : Dalam suatu sistem informasi, landasan yang utama adalah database dan implementasi prgoram. Database yang tidak efektif dan implementasi program yang tidak terstruktur dapat mempengaruhi performansi sistem informasi tersebut. Pengaruh desain terhadap database sangatlah besar, termasuk desain data, tipe data maupun relasinya. Pembuatan desain yang tidak dibangun dengan cermat dapat menyebabkan hilangnya data yang dibutuhkan, data yang tidak konsisten, redundansi data, proses update yang lambat dan banyak hal lain. Untuk menghindari hal tersebut, dibuatlah beberapa contoh kasus yang dapat menunjukkan betapa pentingnya desain sebelum pembuatan database yaitu pembuatan logical data model. Dari contoh kasus yang diberikan, dapat dilihat bahwa desain mempengaruhi database yang akan dibentuk. Kata kunci: database, logical data model.
