Abstract

This study aims to introduce question-based computational thinking to elementary school students. The background is the study that education in Indonesia needs to be improved in order to answer the global competition in the 21st century which is full of technological and information developments. In today's era everything is integrated with computers and technology, therefore it is necessary to be equipped with Computational Thinking which is believed to be able to train the brain to get used to thinking logically and structurally so that they are faster. Therefore, the development of Computational Thinking learning media was carried out by teaching using questions consisting of 4 categories and totaling 17 questions which were applied to the media. The media development model used was ADDIE (Analyze, Design, Development, Implementation, Evaluate) with a sample of 6 students from grade 6 SDIT 'Alamy Subang. The results of this study indicate that: The instructional media has been evaluated and rated "Very Good" by experts with an average percentage of feasibility of 96.19%. Computational Thinking skills possessed by students vary and have different abilities in each question category and have different levels of difficulty according to the abilities possessed by each student. Students' responses to learning media are enabling students to learn new things and get an average percentage score of 87.11% and are included in the "Very Good" category.

Abstract

The use of hands-on activity-based mathematics learning media for mentally retarded children and cerebral palsy is largely unexplored. Meanwhile, observations of children with special needs (mental retardation and cerebral palsy) at school have not shown good basic math skills, such as counting, recognizing numbers, recognizing letters, performing math operations (for example, addition and subtraction). This study aims to develop a hands-on activity-based learning media model for mentally retarded children and cerebral palsy to improve understanding of mathematics in reading, writing, and arithmetic subjects. The method used is Research and Development, where the subject is the Special School in Bandung, Indonesia. The instruments used in this study were documentation, classroom observation, interviews, and tests of mathematical comprehension abilities. The results showed that a hands-on activity-based learning model could be used to improve basic math skills in reading, writing, and arithmetic for children with mental retardation and cerebral palsy.

Abstract

This study aims to test the reliability, validity and wright person-items of the test instrument. It used to measure students' cognitive system thinking in genetics lectures. This cognitive system dimension (New Marzano Taxonomy) consists of 4 levels: retrieval, comprehension, analysis, and knowledge utilization. The research method used was descriptive quantitative, with respondents as many as 116 undergraduate students who had attended genetics lectures. The instrument used consisted of 20 multiple-choice questions developed from 4 levels of the cognitive dimension of the system. Data analysis using the Rasch Model-Dichotom to generate more accurate estimates based on individual abilities and difficulty levels of question items. The results showed that the Alpha Cronbach and Item Reliability value on the instrument was 0.81 (Very Good) to 0.92 (Best). Furthermore, person reliability is 0.63 (Moderate). It can be concluded the interaction between the question items and the quality of the question items on the test instrument indicates that the instrument effectively assesses constructs and is relevant for measuring the level of cognitive system thinking. Revisions are made to items that are too easy or too difficult, as well as a review of items with similar difficulties. So it can be assessed that this test has the potential to be widely used in measuring cognitive ability, but some improvements are needed to further improve its reliability for other population.

Abstract

This research aims to develop a Data-to-Text system with input in the form of streaming data in batch form, to generate news in general. The development of a Data-to-Text system model is carried out by applying Machine Learning to overcome Streaming data, with the Piecewise Linear Approximation technique using the Least Square method. The developed system produces data summary information, current data information, and prediction information. System development is carried out in the R programming language by utilizing several available packages. The experiment was conducted by measuring the Readability level of the news raised, Computation Time, and comparing the results withrelated research. The experimental results show that the information produced is proven to represent the data provided and can be understood by the student level or above, and the computational time is quite good. The system can generate information based on meteorological data, climatological data, and financial data.

Abstract

Solar flares (SFs) are the most powerful bursts of energy in the solar system that often have a bad effect on space weather. Until now, the cause of its appearance is not known for sure. Nevertheless, SFs are known to have magnetic properties attached to them. Therefore, understanding the configuration of the magnetic field on the sun plays an important role in SFs prediction efforts. Using SFs flux data recorded by X-ray Sensors on the Geostationary Operational Environmental Satellite (GOES) which is mapped with 13 parameters of the magnetic vector data of the solar photosphere layer recorded by the Helioseismic and Magnetic Imager (HMI) at the Solar Dynamic Observatory (SDO) and the Machine Learning (ML) Random Ferns (RFe) algorithm,  This study tries to predict the emergence of multiclass SFs (B, C, M, and X) along with binary SFs (BC and MX). This study uses data from May 1, 2010 to May 10, 2020, with a total of 30 classes X, 443 classes M, 1032 classes C, 751 classes B, 473 classes MX, and 1783 classes BC. This study also applies the oversampling method to handle the imbalanced nature of the data on SFs data. Overall, it can be seen that predicting the occurrence of SFs using RFe is a valid effort. The highest average scores achieved by this study for sensitivity/recall, precision, and True Skill Statistics (TSS) in multiclass SFs were 74.4%, 50.3%, and 58.7%, respectively; and in binary SFs are 87.7%, 77.7%, and 72.8%.

Abstract

Atrial Fibrillation (AF) is one of the most common heart diseases and increases the risk of stroke and heart failure up to five times. The symptoms of AF are very diverse and often asymptomatic, so an immediate examination is needed to detect it. Given the dangers of AF that could lead to heart failure or death, a diagnosis that can record daily heart rhythms is urgently needed. Research trends show increased use of the Internet of Things (IoT) due to its efficiency and real-time monitoring capabilities. The purpose of this study is to utilize the IoT concept by designing a prototype AF detection device called Atrial Fibrillation Detector (AFD) using a ESP8266 microcontroller device and an AD8266 Electrocardiogram (ECG) sensor. The results of the study show that AFD can identify AF through 4 main stages, including the process of recording ECG data, the process of sending data from the AFD device to the server, the process of processing data to identify the appearance of AF and the process of sending notifications if there is an indication of the appearance of AF. To further test AFD, two experimental scenarios were applied; blackbox testing and comparison of the suitability of AF detection results. In the first experiment, AFD managed to pass the total number of scenarios that existed at 16 scenarios. In the second experiment, AFD only managed to identify exactly 9 out of 15 scenarios.
