Abstract

The Covid-19 explosion has changed all activities, including the learning process. The existence this pandemic makes all sectors try to find the best solution. This needs to be done so that all systems are well maintained. One solution during the pandemic is learning activities with online activities. Online learning without face to face certainly raises some problems. New activities make teachers and students must adapt to new learning conditions. In addition, various obstacles provide a paradigm that applying online learning is difficult. The difficulty of carrying out online learning is certainly not only felt by student but also teacher feel the same way. However, it is the teacher’s responsibility to address their difficulties and students’ difficulties. To determine an effective solution in overcoming students’ difficulties, further research is needed to determine the aspect that promote students’ difficulties in online learning. Through this survey research, researchers wanted to see how mathematics teacher’s perception about students’ difficulties when participating in online learning. Most teachers’ perceptions indicate that aspects of facilities and infrastructure, learning activities and environment are the main factors which promote students’ difficulties in online learning.Keywords: perception of athematics teacher, students’ difficulties, online learning

Abstract

Tujuan penelitian ini ditulis dengan maksud membangun kesadaran siswa terhadap metode belajar matematika menggunakan konten digital. Artikel ini disusun berdasarkan penilaian penulis tentang seiring dengan gerakan perkembangan teknologi yang canggih. Salah satu hasil kemajuan teknologi dan pengetahuan di era saat ini adalah YouTube. Penelitian tersebut menggunakan metode penelitian kualitatif deskriptif yaitu salah satu metode penelitian yang bertujuan untuk memahami perilaku manusia dalam menginterpretasikan sudut pandangnya tehadap dunianya. Objek dalam penelitian ini adalah konten edukasi matematika di saluran YouTube Jerome Polin, sedangkan subjek penelitiannya adalah siswa kelas XI pada salah satu madrasah di Kudus dengan menggunakan sumber data wawancara. Artikel ini membahas mengenai pembelajaran matematika menggunakan konten digital dengan menonton video matematika di saluran YouTube Jerome Polin, salah satunya adalah video Battle Matematika yang dapat mempengaruhi motivasi belajar matematika siswa sehingga menimbulkan adanya respon positif. Berdasarkan hasil respon siswa terhadap konten edukasi matematika di YouTube Jerome Polin didapatkan hasil yakni adanya video matematika Jerome Polin ini memberikan kontribusi yang baik dalam meningkatkan motivasi belajar siswa sehingga hal ini menunjukkan adanya respon positif dan menjadikannya sebagai inspirasi dan motivasi belajar. Keberhasilan pembelajaran matematika dengan konten ditunjukkan apabila respon siswa positif tentang pembelajaran matematika menggunakan konten media digital tersebut. Konten digital dinilai cocok untuk mengembangkan pembelajaran matematika siswa kelas XI. Oleh karena itu, belajar matematika menggunakan konten penting bagi siswa dalam menghadapi revolusi industri 4.0.

Abstract

Perdagangan secara umum dikelompokkan menjadi dua yaitu, ekspor dan impor. Salah satu contoh perdagangan tersebut adalah minyak mentah. Diketahui saat ini harga pasar minyak mentah dunia mempengaruhi tingkat perekonomian global. Harga minyak yang terus berubah, tentu saja menjadi sumber kekhawatiran dan perhatian tersendiri, terutama dalam industri minyak. Dalam penelitian ini, akan mengkaji harga minyak mentah menggunakan model ARIMAX (Autoregressive Integrated Moving Average with Exogenous Variables). Model ARIMAX dipilih karena mampu mengintegrasikan variabel eksternal, seperti volume nilai tukar rupiah dan produksi minyak, yang mempengaruhi harga minyak mentah. Tujuan utama penelitian ini adalah untuk mengembangkan model prediktif yang akurat dengan mempertimbangkan pengaruh produksi minyak (Richard et al., 2021)dan nilai tukar rupiah terhadap harga minyak mentah dunia. Berdasarkan hasil analisis model ARIMAX (0,1,2) merupakan model terbaik dalam meramalkan harga minyak mentah dunia karena memiliki nilai AIC dan MAPE terkecil, yaitu AIC sebesar 408,49 dan MAPE 8,88. Berdasarkan hasil tersebut peramalan dengan model model ARIMAX (0,1,2) dapat dikategorikan sangat baik.Kata Kunci: ARIMAX, Perekonomian, Harga minyak mentah dunia, Nilai tukar rupiah, Produksi minyak.

Abstract

This study aims to determine the feasibility of developing the SETREASURE learning media that has been developed and to determine the students' responses to the SETREASURE learning media. SETREASURE is aimed at seventh grade students, especially on set material. This research was conducted using the Research and Development method with the ADDIE development procedure (Analyze, Design, Development, Implementation, and Evaluation) using the Construct2 application and the web2apk. The data collection technique used a validation questionnaire in material validation sheets, media validation sheets, and student response questionnaires. The developed learning media application is equipped with material especially on in seventh grade. The feature of application, such as  explanations, videos, sample questions, practice questions, and game score results.The data analysis technique in the form of an assessment score was carried out quantitatively.  Based on the validation results of the learning media, SETREASURE is very feasible with a score of 83.33% on the material aspect and 81.67% on the media aspect with a note of slight improvement, as well as the results of the student response questionnaire were given a percentage of 83.21%. Students also gave a positive response to the SETREASURE learning media so that it can be stated that this learning media is very interesting for students.Keywords: Construct2, Learning Game, Mathematics Learning Media, Sets

Abstract

This research employs the ARIMA model to conduct a thorough time series analysis on the treatment of typhoid (enteric) fever in Maiduguri. The study reveals the presence of both trend and seasonality in the data, with the trend indicating a recent reduction in the recorded data. Using autocorrelation and partial autocorrelation function (ACF and PACF), the data can also be utilized to determine the model's order. The model obtained is subjected to model diagnostics to determine its efficiency and the model is used to forecast the typhoid fever. From the forecast graph shows that there may be a decrease in future years due to the pattern of the series the impression, we obtain from the graph is that predicted series seems to be trend upward and then downward. ARIMA (1,0,0) has the minimum value of AIC therefore it found to be best model. Hence, the model to fit the typhoid fever based on diplomatic test, which is LJung Box test from the family of Box Janks procedure, then our P-value is less than 0.05 level of significant, we reject the null hypothesis and conclude that the typhoid fever is statistically significant at 5% level of significant. Forecast of typhoid fever from February to December 2025 we also conclude that the typhoid fever is stable. Improve Sanitation and Hygiene: Implement measures to improve sanitation and hygiene practices, especially in areas with high disease prevalence. This may include promoting access to clean water, proper waste management, and hygiene education campaigns.Keyword: ARIMA Model, Typhoid fever, Box janks, WHO, Model diagnostic.
