Published: June 2020

Abstract
Time-series data is one of the data produced by the Badan Pusat Statistik (BPS). The time-series data has the potential to have a seasonal effect which can cause the analysis to be less accurate. Seasonal effects can be eliminated by making seasonal adjustments (SA). An understanding of SA is needed by BPS employees in analyzing time series data. Therefore we need a form of web-based learning that can be reached by all BPS employees. The goals of the system to accommodate the needs of users to get learning materials related to statistical material and provides convenience to users in implementing seasonal adjustments. An important feature that needed in this learning system is a simulation tool. The learning system is built using the SDLC method. In its development, the system uses the PHP programming language which is used as the main backend of web-based learning and R as a programming language in simulation applications. Data processing application simulation with seasonal adjustment method is built using the Jdemetra + package which is integrated with R Shiny. The evaluation results show that the system built was acceptable to the user with a SUS value of 73.8. The results showed that the participants can use the learning and simulation system as a pedagogical tool on SA learning.

Published: June 2020

Abstract
Exploratory Data Analysis (EDA) is one of the basic statistics subjects that needs to be studied as a basis for higher processing and analyzing data. This subject is taught in class, but these activities are not necessarily enough to understand the subject. This problem can be solved by learning independently. However, in the process of learning independently there are obstacles such as the unavailability of suitable material so that a search is needed which may not produce anything or if the material is available in book or textbook format, the material is less flexible in its use. An e-learning system needs to be developed to solve these problems. In addition, simulation can also help students’ understanding in building knowledge base. Furthermore, the use of smartphones with the Android operating system is the most used by Politeknik Statistika STIS students. Based on these problems, an e-learning system and statistical simulation will be built for this Android-based EDA subject. In its development, we use Java programming language and integrate with R Shiny for statistical simulations in the form of data processing. Evaluation shows that the system can be accepted by users as indicated by the Black Box test results and the SUS value of 84.13. The system still consist of basic features and still need to be improved with advanced features so can support the learning activities of EDA.
