Abstract

The accounting information system is an important key to financial management, the information influences the company’s decisionmaking in determining its future strategy. However, before the development of web technology, current systems were usually implemented on desktop platforms. Over time, many obstacles were found during its implementation, which had an impact on time efficiency on staff performance. Therefore, in this study, a preliminary review assessment is made to find out whether the current desktop information system is still good for use or a web-based system is able to provide more performance, especially in terms of time efficiency. According to the results of this study, web information systems have better performance than desktops. With the transformation of the platform in the system, there was an increase in the use of time in carrying out input process activities of 35%.

Abstract

Many companies have begun to adopt both ways of working simultaneously or commonly referred to as Work From Anywhere (WFA); it is necessary to model business processes used to evaluate and improve the WFA work system in the future. In modelling business processes, it is necessary to carry out a needs analysis, one of which is to find out what factors affect employee productivity when doing their work. Several research journals related to WFA work productivity factors are still scattered in various journal databases, so it is necessary to unify them from various journals. Therefore, it is necessary to research the grouping of factors and theories that affect the productivity of WFA employees in the Systematic Literature Review (SLR) method. Before grouping, the search criteria and journal search process are determined first. The first search is to identify based on keywords, year of publication, and journal quality. Then continued, the use of Cohen's Kappa method for selection based on the field of discussion and language, abstracts, and contents. In improving the reliability of the library screening results, each selection is made twice (or more) and calculates the value of Cohen's Kappa. The SLR method makes the usually subjective literature study more objective to reduce the researcher's bias. The results obtained were a total of 17 screening journals with a total of 11 factors, namely environment, time efficiency, psychology, health, cost efficiency, employee personality, adequate technology, gender, geographical flexibility, salary, and communication.

Abstract

Representational State Transfer (REST) is an architectural style that underlies the protocol of HyperText Transfer Protocol (HTTP)and is used by web applications. The implementation of REST principles in web services is often known as RESTful API. The standard communication used in RESTful APIs uses HTTP without involving data compression. There are quite a lot of RESTful API clients in the form of mobile applications that use metered networks. Thus, reducing the required bandwidth during transmission is suggested to be beneficial. The data compression technique is widely known to reduce data size, but this additional step may yield side effects such as increased memory usage and processing time. This study aims to investigate how the data compression process, which specifically uses Zlib and Base64 encoding, may put additional load on the whole process of delivering content to a RESTful API. The performance and characteristics in terms of bandwidth saved when distributing JSON data from a RESTful API in compressed format are also be investigated. According to the experiment result, it is suggested that the compression process can reduce network bandwidth by up to 66% with negligible additional memory usage for the compression and decompression processes.

Abstract

Information system is one of the most important business supports in organizations. Web-based applications become an appropriate solution to overcome the dynamically changing environment among different units in an organization. Model-View-Controller (MVC) is a well-known design pattern in web-based application development due to the separation of an application into several parts, hence it is easy to reuse and maintain. However, such design pattern requires improvements since the information system handles business process choreography and integration between application. Therefore, modifying the interaction of object of class in a design pattern become a challenging problem. In this paper, an application framework based on Model-CollectionService-Controller-Presenter (MCCP) design pattern, which is a modification of an MVC, was proposed. The proposed framework allows multiple different applications to run and provides inter-application data exchange mechanisms to improve the data communication process between applications. Several performance comparisons with another popular web application framework are also presented.

Abstract

Education becomes an important thing to advance a nation. Therefore, everyone must follow the education level. One of education level is early childhood education. KB & TK Permata Iman which was established in 2005 is a private educational institution and focus on early childhood education. In learning evaluation, KB & TK Permata Iman still use conventional method. The conventional method takes much time because teachers need to collect daily grade until the end of a semester for final grade calculation and prepare the results in grade book. The semester learning evaluation process can be shortened and simplified using a web-based academic assessment management information system. The system can store, directly perform calculations when teachers add students’ grade and make grade book from saved grade. From the testing result, the time efficiency increased to 94.94% when evaluating semester learning using the system and it can help the teacher to save time and do another task.

Abstract

Paratransit (mikrolet) was very popular in Malang city. However, their popularity is reduced by the availability of wide variety of more modern and online public transportations. One of the obstacles commonly faced by passengers of mikrolet is the limited information about the routes taken by mikrolet. In this paper, we proposed a prototype of service that can generate trip planning by mikrolet. We use depth-first search (DFS) algorithm as the basis to build our solution because it is relatively simple to modify. The service for trip planning available through REST web service and utilize location-based service style. Based on functionality testing result, the proposed system successfully generate all trip plans as expected. From performance perspective, when the number of routes and plans increased, the overall system performance degrades, so in the future the proposed prototype and its algorithm may needs further optimization.
