Abstract

Using a mobile application that is featured with local public transit information can greatly improve user action, as well as assisting travelers to have a better experience while taking public transit services. Crowd environment inside a public transit is one of the most frequent causes that lead difficulties to passengers when they engaging their mobile devices to access their apps or in some conditions. Finding crucial information such as stops points and remaining time to interchanges point when switching to another line becomes more difficult in those conditions especially for foreigners who new in a particular region. This study presents the combination of a mental model and a usability approach to construct a user journey map that led to new insights on user's experiences and challenges when utilizing their mobile local transit application. This valuable information is a part of the elicitation process to propose an alternative interaction method to enhance the usability and travel experience of the public transit app. The experimental results indicate that in contrast to the existing mobile transit app, the proposed interface with the utilization of a wearable device could considerably enhance user action when trying to reach the desired location in terms of total time and performance. It implies that the proposed solution, which works through the mental model and user journey is able to intuitively enhance the public transit app usability.

Abstract

Education is an essential need and an important element to create a broad-minded youth. While in Indonesia, the rate of tuition fees is still imbalanced with the economic rate. Thus, many people decided to discontinue their higher education. Decision making plays an important role to manage organizations, including in educational institutions, as one of the main duties in managerial is making decisions. This study took place in a midwifery academy in Malang. In response to this situation, the academy has a policy to alleviate students by paying the tuition fees in instalments. However, many students are in arrears as the result of this policy. Thus, management needs to take some consideration before making a decision toward the problem. Those considerations require high accuracy and time consuming to process information that support decision making. Currently, the decision-making process in this academy is still semi-automated, in which some processes are still done manually, which affect longer time to make decisions, and the accuracy of calculations could not be fully guaranteed. According to this condition, the purpose of this research is to design a decision support system that enables us to process information for decision making and to offer decision alternatives for decision makers. This research employs Systems Development Life Cycle (SDLC) with a decision table as a method to create decision alternatives. The prototype was developed using Visual Studio C#.Net. The result shows that by using the proposed prototype of DSS, decision makers can reduce 5-10 minutes of decision making process compared to the old semi-automated system which still required manual calculation and data collection and analysis before making the decision. A complete data and more detailed parameters for decision criteria are required to implement the proposed prototype of DSS in the institution with more objective consideration in the decision making process as the future work.

Abstract

The data in the data warehouse can be extracted from many sources through the ETL (extract, transform, and load) processes. The scheduling process in ETL data warehouse is a process that must be passed for the establishment of data warehouse. Problems that arise when performing the scheduling process for the ETL process are to perform the ETL process for very large data, it will require a very large time cost as well. If it is not handled properly, it will probably take a very long time for execution and inconsistency data. The ETL process in the conventional way (not using the Round-Robin method) will be tested and compared with the ETL process using the Round-Robin method to obtain test results for this research. The difference between these two processes is the number of partition tables used in the ETL process. In the ETL process of the Round-robin method, the table target will be partitioned into sections, whereas for the conventional way there is no need to partitioning the table target. After the trial is complete, the difference between the two methods is found in terms of execution time. Through the experiment, it is concluded that the Round-robin method gives a more efficient execution time up to 60,1% depending on the amount of data and the number of partitions used.

Abstract

To create an Android application, developers need to consider things other than security, such as application performance, because Android itself as a mobile device inherently has limited resources so that efforts to improve the performance of applications developed specifically for the Android platform needs to be done. Questions on developer forums such as Stackoverflow on which algorithms are performing better on Android platforms are emerging, to answer those questions there will be a performance comparison between two well-known and popularly used cryptographic algorithms, AES and Blowfish. The study chose two popular symmetric cryptography algorithms that are used: Advanced Encryption Standard (AES) algorithms and Blowfish algorithms to compare performance on the Android operating system. The data used derived from the generator data based on certain rules. Comparison of performance will be done with 3 parameters, namely: data length, key length, and differences in processor architecture. Testing each data is done 20 times to improve the accuracy of algorithmic performance. The test results show that the Blowfish algorithm has better encryption and decryption performance than the AES algorithm on testing of data length and key length, on testing of Intel AES processor is superior to 0.3-0.4 ms faster while on ARM processor Blowfish is faster by 0.2 Ms.
