Abstract

Computer networks have penetrated into various fields including education for the learning process which is used as a medium for delivering scientific concepts to be more attractive and easily accepted. The Muhammadiyah University of Palembang currently has very high mobility, both used for browsing information, downloading data and using other facilities. For the need for bandwidth management to manage each passing data so that the distribution of bandwidth becomes evenly distributed by using the queue tree method that is applied to the proxy. To evaluate internet bandwidth analyze QoS (Quality of Service) using typhoid standardization in terms of measurement of throughput, delay, and packet loss. The results of this study show that the quality of the network with the hierarchical token bucket method is more optimal, this is because the bandwidth will be divided according to the rules applied to bandwidth management and does not cause clients to fight over bandwidth

Abstract

The development of technology in the telecommunications sector is now easier to be enjoyed by the community. Almost all regions have been able to enjoy the ease of access to information through telecommunications networks. Telecommunications service providers certainly have competed in such a way as to be able to hold users to remain loyal to the provider used. From several surveys conducted, there are still many users who cannot be loyal to use the services of these providers. The increasing number of communication network providers makes users more choices. Various ways are carried out by communication network providers to maintain their users such as giving bonuses, providing cheap rates, increasing services to the regions. In this study will focus on the level of customer satisfaction with cellular operators with a variety of criteria that have been prepared which will be a consideration for users in using these cellular operators. This research will use the AHP method (Analytic Hierarchy Process) to find out which cellular operators are the most superior based on the judgment of the user with various criteria each. So that in the end it will be known which cellular operators will be selected and purchased by consumers according to their respective needs. The results of this study show that based on the bonus, IM3 is the best with a weight of 0.21712. Then based on the price rate, a tri card with a weight of 0.16565. Furthermore, the service criteria show a better Sympathy card with a weight of 0.21311

Abstract

Energy and mining reporting have to conduct for the exploration company in order to make control while exploration. Government control can perform by making profiling of energy and mining data that exist in the area as consideration in taking policy or decision. Stages of energy and mining reporting are very important to do especially in areas that have energy and mining resources such as Musi Banyuasin regency. Profiling can performed by mapping the location of energy and mining results using a geographic information system (GIS) to organize data between explorers and governments. Based on these conditions GIS was developed using a technique that prioritizes user needs with extreme programming development techniques. The result of GIS development shows that the processing of data becomes information based on spatial and non-spatial data with the final result of energy and mining report. The report presented can be used as a report to the relevant parties as an effort to open data of energy and mining as material in decision-making or policy. Geographic information system generated systematically developed using extreme programming approach with five stages of exploration, planning, iteration, production and maintenance so that it can run funtionaly according to its function

Abstract

Modeling is a tool in the process of developing an information system. Modeling has ability to look how blueprint an information system and make it easier to understand an information system to be created. Modeling can be done by visual modeling using unified modeling language (UML). Therefore, this research performs modeling of information system of monitoring of regional secretariat inventory of Musi Banyuasin Regency. The implementation procedure starts from determining the information system specification based on user requirement, followed by making modeling according to specification. The end result obtained is a prototype information system that can provide reports of goods consisting of the lifetime of goods, borrowing goods and goods with damaged conditions. In addition, the prototype can illustrate how the monitoring process is done based on color indicators consisting of green, yellow and red. Green means lifetime is still safe, yellow means lifetime will expired and red means expired.Keywords: Modeling, Information System, Inventory, UMLPemodelan merupakan alat bantu dalam proses pengembangan sebuah sistem informasi.

Abstract

The focus of this research is to design and implement a small medium industry database for the Palembang City Government. The database needs of small and medium industries due to the unavailability of data quickly and accurately when it requires information by the Department of Industry in policy making. The design and implementation of the IKM database has stages carried out starting from the needs analysis, database formation, information modeling, dashboard manufacturing, to testing. The resulting dashboard can provide data in the form of graphs and tables relating to small and medium industries either through the criteria of the region or type of industry. The layout and presentation of the data has been validated using a heuristic evaluation approach involving three experts. The validation results show that all experts agree that the results of the design and implementation of small medium industry databases do not have usability problems as evidenced by the results of the average expert testing giving a value of 0.Keywords—Database, heuristic evaluation, industry, IKM

Abstract

Clean water is the need of every human being, for that the necessity of clean water is a priority for the government in providing services. The current problem is the lack of clean water that has not been evenly distributed due to government limitations. For that reason, in providing services, it must be according to priority in order to have a broad impact on the community. For this reason, in this research the development of an information system can be used to assist in determining priorities in handling clean water sources. In the development process the waterfall method is used while the determination of priorities uses simple additive weighting. The results showed that the simple additive weighting method can provide a clear value in determining the priority of clean water handling. This condition can be seen from the existing process in the information system, which starts from weighting, filling the survey value to simple additive weighting calculations. besides that, the information system can run well in accordance with the expected proven by the results of testing using black box testing to get the test results received

Abstract

Test engine try out is an information system used by prospective alumni students to practice the questions in taking the certification exams at Bina Darma University. Exercises that can be done on this test engine are vendor certifications such as Microsoft Technology Associate, SAP, NIIT, PASAS, CISCO, and various other certifications. To ascertain whether the test engine is in line with the expectations and needs of the participants try out then an evaluation is carried out. The evaluation technique used is usability with the system usability scale approach. System usability scale is an information system evaluation technique that looks at three aspects, namely adjective rating, grade scale, acceptability by involving end users in the evaluation process. In the process of evaluating the usability scale system, ten instruments were used as a measure of evaluation. From the evaluation, the final result is 87.33. According to these conditions, it can be concluded that the test engine try out from the side of the adjective rating includes the excellence group, from the grade scale side including B group, and from the acceptability side including the acceptable group.
