Combined Model Time Series Regression – ARIMA on Stocks Prices

Stock price data tend to experience a linear trend and fluctuate over time. So that forecasting is needed to predict stock prices in the next period. The nature of the linear trend can be modeled by linear time series regression and ARIMA. The purpose of this study is to form a combined model time series regression linear – ARIMA and predict stock prices using the combined mode time series regression linear – ARIMA. Combining two models can increase the level of forecasting accuracy compared to using separate models. The data used is the daily closing price of PT Unilever Indonesia Tbk for the period January 4, 2021 to December 30, 2021. The data forms a trend pattern that tends to be linear. The data is divided into in sample and out sample data with a proportion of 80:20. The model time series regression linear is formed by regressing the trend variable and stock closing price variable. From the model time series regression, the residual value is sought that will be used to form the ARIMA model. The model time series regression linear is then combined with the ARIMA model, where the model formed is a combined model time series regression linear – ARIMA (0,1,1) with the MAPE is 1.349906%. The results of PT Unilever Tbk’s stock price forecasting for the period January 3, 2022 to January 21, 2022, continued to decline. The highest forecasting results occurred on January 3, 2022, amounting to 4,091.253. While the lowest forecasting results occurred on January 21, 2022, which amounted to 3,827.192.

Overcoming Classroom Silence

Engagement is one of the essential aspects of having effective communication in English. In reality, English speakers, specifically language learners, often struggle and are unresponsive in communication, including in the classroom. This contradicts the purpose of learning that requires students and teachers to communicate effectively. In response to this issue, it is necessary to understand how teachers handle the problem through teaching strategies. This paper investigates teachers' strategies for engaging unresponsive students to teachers' questions. It is a qualitative study, with data collected through observations and interviews. The subject is an English teacher at SMKN 1 Tapin who taught tenth-grade students. The results show that the teacher used several strategies in engaging with unresponsive students, including humor, effective pacing, demonstrating intensity and enthusiasm, and pair work. Additionally, she also did code-mix with students' native language, constantly asking other students, and giving rewards. This proves the teacher's ability in exploring creative strategies to be engaging with her students.
Needs Analysis for Developing Virtual Field Trips-Based Learning Media in Elementary School Science Learning

Since the COVID-19 pandemic, various technology-based learning media have been developed, including various museums and institutions' availability of Virtual Field Trips (VFT). This can be considered an innovation in science learning that is expected to enhance students' cognitive and affective abilities. This research aims to analyze the need for developing VFT-based learning media in science education at the elementary school level. The study adopts a qualitative approach by collecting quantitative and qualitative data from questionnaire surveys. The respondents, consisting of 33 elementary school teachers from various regions in Indonesia, are familiar with using electronic devices and internet connectivity to support technology-based learning, which is already widely implemented in their science classes. Moreover, elementary school teachers are accustomed to using technology-based learning media in science education. However, there is a need to develop technology-based learning media, particularly Virtual Field Trips (VFT), in science education at the elementary school level as an innovative approach to teaching. Therefore, further research on developing VFT-based learning media in science education at the elementary school level is warranted.
The Effect of Applying English Authentic Reading Materials on The Eleventh Grade Students’ Reading Comprehension Achievement at SMAN 1 Tanjungbalai

Tendency in Indonesian Newspaper Editorials: Genre and APPRAISAL Studies

Editorial is an important part of newspapers since the opinions expressed can influence the reader's point of view. The two major Indonesian news media that publish editorials in their newspapers are Kompas and Tempo. This study explores the potential differences in editorial characters between Kompas and Tempo regarding the 2024 election issue. To achieve this goal, the organizational structure of editorial texts is examined and their attitudinal tendencies are investigated. The method used in this study is analytical discourse framework by Systemic Functional Linguistics (SFL) in particular genre (Iedema, et al., 1994) and APPRAISAL framework (Martin White, 2005). Based on the findings of genre and APPRAISAL in the text, it is revealed that the editorials of Tempo tend to be explicit in showing their position against 2024 election issues. Tempo uses the genre of media exposition and built their attitudinal tendencies by using negative evaluations. Unlike Tempo, Kompas tends to be implicit in showing their position against the said issue. They adopted media discussion genre and their attitudinal tendency is built using positive evaluations. The results of this study reveal that in examining the character of a media, an analysis of editorial text genres needs to be carried out before investigating its attitudinal tendencies.Keywords: APPRAISAL, genre, discourse analysis, newspaper, editorial

A Novel Method for Failure Detection Based on Real-Time Systems Identification

The current state of climatic emergency that we are suffering, combined with the increase in population, is causing water availability to decrease. Therefore, the water distribution and management systems in cities and industrial areas correspond to a critical system. It is, therefore, essential to ensure the robust operation of these kind of systems. In this context, this paper presents a novel proposal for detecting real-time malfunctions in water resource management systems. The proposed method is based on combining the Recursive Least Squares method and detecting hyperplanes using regression methods. The proposal has been validated using a real dataset, and the results obtained have reached 80% F1-score.
DESIGN FOR EXTENDED REALITY (DFXR) – EXPLORING ENGINEERING AND PRODUCT DESIGN EDUCATION IN XR

With the rapid improvements and efforts made to improve ways to utilize eXtended Reality (XR) this paper looks at how sustainability considerations to XR are affecting the design process. Although internationalization is one of many advantages of XR, higher education research repeatedly recalls and builds upon local use-cases rather than more global interconnected alternatives. Many universities are currently developing their digital capabilities where XR is an enabler for various educational purposes. Although many learning examples are built around an authentic and local practice, the global possibilities of interceded activities using multiple variations of XR (i.e. VR, AR or MR) are rare. It is arguably important to establish more interconnected set of use-cases in order to excel this technology practice. Also, past methodological considerations have also been presented through guided design steps once working with elements of XR. This paper, however, concentrate on the need for a XR scrutinizing process of sustainability. Addressing international collaboration, use and practices of team-based design processes are looked at to see the effect XR can have direct and indirect on sustainability's three pillars of environmental, economic and social concern. A qualitative exploration using AR and VR experiments, and interviews with groups of design students, expert-users and solution-providers. All cases investigated are characterized by internationalization, involving multiple nodes, (e.g. partnering companies and universities). The paper is built on insights from several international co-design projects and looks in detail at how design aspects are emphasized on activity-level, and by also uncovering involved activities. The aim is to explore how digital enabled design using XR can be presented from a sustainability point-of-view. Rather than looking at output of a use-case scenario, the process of how to reach there, is at focal point. What is referred to as the Open XR runtime standards are currently extending the possibilities between hardware and software interoperability, which can potentially increase XR sustainability by making the technology more accessible. By identifying and exploring remote design processes, collaborations that utilize a mix of technological platforms is looked at and how interaction of XR practices and processes affect aspects like internationalization and interconnectedness. With a growing number of students, professional workers and companies trying to benefit and excel from new remote-working norms, a better understanding is needed to support distributed and sustained XR collaboration. Ultimately, this paper can bring more attention to how XR is practiced and how sustainability affects several digitally enabled prototyping steps and practices.
Raw data and the evolution of crystallographic FAIR data. Journals, processed and raw structure data.

In my previous post on the topic,&amp;nbsp;I introduced the concept that data can come in several forms, most commonly as “raw” or primary data and as a “processed” version of this data that has added value. In crystallography, the chemist is interested in this processed version, carried by a CIF file.
VALIDATION OF TROPICAL RAINFALL MEASURING MISSION (TRMM) RAINFALL DATA FOR THE KAPUAS HULU DISTRICT AREA

Rainfall is a critical element in the hydrological cycle. Therefore, accurate rainfall inputs are essential for reliable hydrological predictions in various water resource analyses. Many areas in the tropics depend on rainfall for multiple needs because rainfall has an essential influence on numerous aspects of human life, especially in water resources planning and management. However, not all areas have rainfall recording stations using manual rain and gauges or automatic rainfall recorders, so rainfall records are rarely complete; this is also the case in Kapuas Hulu District, West Kalimantan Province.This research article presents the results of TRMM satellite rainfall data research in Kapuas Hulu District, with validated rainfall data, 1-day maximum rainfall data, and rainfall amount data. Validation stages are carried out by calibrating, verifying, and correcting rainfall data. As a comparison station (dependent variable) is the BMKG Pangsuma observation station, KPH-06 Nanga Kantuk, KPH-08 Ng. Silat, KPH-09 Jongkong, KPH-13 Tepuai in 1998-2019.The results of the analysis show that the best correlation value on the amount of rainfall data and 1-day maximum rainfall data obtained from Grid 30 TRMM of 0.83 and 0.82 with the observation station is BMKG Pangsuma Station, and then the equation obtained from the analysis results on the grid is used as an equation for correction. The data correction equation for the amount of rainfall is Y = 1.1578 X - 98.5547, and the 1-day maximum rainfall data correction equation is Y = 1.2036 X - 28.4197.
Physical Sample identifiers &amp;#8211; the future?

I have variously talked about persistent identifiers on this blog. These largely take the form of DOIs (Digital object identifiers), and here they relate to either journal articles or datasets associated with either the article or the blog post or both. Other disciplines, particularly the earth sciences, have long used persistent identifiers (PIDs) to identify physical objects rather than digital ones.
HPC Access and Metadata Portal (CHAMP).

You might have noticed if you have read any of my posts here is that many of them have been accompanied since 2006 by supporting calculations, normally based on density functional theory (DFT) and these calculations are accompanied by a persistent identifier pointer &lt;sup&gt; ‡ &lt;/sup&gt; to a data repository publication.

This study is motivated by the low ability of students in analyzing the elements of a short story builder focusing on the plot element of the short story. This is due to the lack of variety of educators in choosing teaching methods and model. The selection of varied teaching methods and model can increase motivation and interest in learning. The purpose of this study was to assess the author's ability to plan, implement, and assess learning using the discovery learning model; assess the ability of students using the discovery learning model; assess the effectiveness of the discovery learning model in learning to analyze the plot elements of short story text; and assess the difference in the ability of the experimental class using the discovery learning model with the control class that applied the discussion method. The research approach used is a pseudo-experimental quantitative approach. The research design was pretest-posttest control group design. The data obtained, namely the pretest and posttest results of the experimental and control classes at Pasundan 1 High School Class XI. The results of this study prove that:1) the author is able to plan, implement, and assess learning by obtaining an average of 4 on planning and 3.84 on implementation; 2) the ability of students increases on the pretest average of 48 to 98.50 on the posttest; 3) discovery learning is effectively used in learning to analyze the plot of short story texts, as evidenced by the results of the Mann-Whitney test showing asymp. sig. 0.002; and 4) there are differences in the ability of students in the experimental class and control class, as evidenced by the results of the Wilcoxon test showing asymp. sig. in the experimental and control classes is 0.003. Thus, the discovery learning model is effectively used in learning to analyze the plot elements of short story text.&#x0D;
