Abstract

This research is a quantitative research employing an ex post facto approach aimed at examining the differences in Grade Point Average (GPA) of mathematics education students based on extrovert and introvert personality types. Data collection was conducted online using a validated personality questionnaire consisting of 20 items, distributed via the Google Form platform. The research sample comprised 28 students, including 14 extroverted and 14 introverted individuals. Data analysis involved a normality test using the Kolmogorov-Smirnov test and a hypothesis test using the Independent Samples t-test. The results showed that there was no significant difference in the GPA of mathematics education students between extrovert and introvert personality types. Therefore, personality type does not significantly influence students' academic achievement in terms of GPA within this context.

Abstract

This study aims to describe and analyze the strategies employed by Islamic Religious Education (PAI) teachers in instilling multicultural values in students at SMA Negeri 1 Merauke, South Papua. The research method employed is a qualitative descriptive approach, utilizing data collection techniques that include observation, interviews, and documentation. The results of the study indicate that the strategies implemented by PAI teachers include inclusive learning, contextual approaches, role models, and strengthening tolerance values ​​through religious and social activities. These strategies play an important role in building an attitude of mutual respect, cooperation between students across cultures, and reducing the potential for conflict caused by differences in background. This study concludes that PAI teachers have a strategic role in shaping students' multicultural character through an integrative and humanistic approach in the learning process. These findings contribute to strengthening multicultural learning in multiethnic areas such as Papua and are relevant to efforts to strengthen character education in Indonesia.

Abstract

Manajemen lalu lintas udara yang efisien dan aman merupakan tantangan utama dalam sistem navigasi penerbangan, terutama di wilayah geografis yang menantang seperti Papua, yang masih memiliki titik kosong dalam pengawasan lalu lintas udara karena keterbatasan infrastruktur radar berbasis darat. Teknologi Space-Based Automatic Dependent Surveillance – Broadcast (ADS-B) muncul sebagai solusi inovatif dengan jangkauan yang lebih luas dan akurasi tinggi tanpa bergantung pada infrastruktur darat. Studi ini menganalisis pemanfaatan ADS-B Berbasis Antariksa dalam mengoptimalkan layanan wilayah udara Papua, mengidentifikasi faktor-faktor yang memengaruhi efektivitasnya, dan mengevaluasi kesiapan penerapannya di Indonesia melalui analisis deskriptif, studi kasus internasional, dan pendekatan statistik. Temuan menunjukkan bahwa teknologi ini memiliki potensi yang signifikan untuk meningkatkan keselamatan dan efisiensi lalu lintas udara karena jangkauan globalnya, akurasi data yang tinggi, dan efisiensi biaya jangka panjang dibandingkan dengan radar berbasis darat. Namun, tantangan tetap ada, termasuk tidak adanya regulasi nasional, biaya operasional yang tinggi, dan kesiapan integrasi dengan sistem manajemen lalu lintas udara yang ada. Oleh karena itu, penelitian ini merekomendasikan pengembangan regulasi nasional, analisis biaya-manfaat yang lebih mendalam, perbaikan infrastruktur komunikasi, dan pelatihan sumber daya manusia untuk memastikan penerapan ADS-B berbasis antariksa secara optimal, menjadikannya solusi utama dalam meningkatkan keselamatan penerbangan dan mendukung sistem pengawasan udara yang lebih efisien di Indonesia.

Abstract

Bessel functions find many applications in Physics and Engineering fields. Some of these applications are in the analysis of extended surface heat transfer where the cross-sections vary. Tables of various kinds of Bessel functions are available in most handbooks of mathematics. However, the use of tables is not always convenient, particularly for applications where many values must be computed. In the applications of Bessel functions in extended surface heat transfer, graphs are also available to provide quick evaluations of the values needed. However, reading these graphs always needs interpolation; this will be cumbersome and time-consuming if there are many readings to be taken. Mathematical formulas for Bessel functions are available but they are usually complicated. Software to calculate values of Bessel functions is also available. Excel, Maple, and Mathematica can also be used to compute the values of Bessel functions. A user can write a program for an application that involves Bessel functions. However, the use of Bessel functions in Excel is limited while Maple and Mathematica are expensive commercial software. In this paper, formulas for Bessel functions of and are simplified with adequate accuracy that can be used to easily compute values needed in the extended surface heat transfer analysis. It is found that errors for and are relatively small (maximum errors are 0.004% and 0.003%, respectively) in the range of 0.05 to 3.75 while the maximum error for is 3.678% for the same range. However, the maximum error for is reduced to 0.166 if the range is from 0.25 to 3.75.

Abstract

This study aims to examine the relationship between breakfast habits and concentration in mathematics learning among seventh-grade students at MTs Al-Amin Kampung Pajak. The research employed a quantitative approach with a correlational design. Data were collected from 59 students using structured interviews, supported by teacher observations. The instrument underwent content validation by experts and was refined through a pilot test prior to implementation. The collected data were categorized into two nominal variables: breakfast habits (had breakfast vs. skipped breakfast) and concentration levels (high vs. low). The Phi coefficient (φ) was used for statistical analysis, supported by the chi-square test. The findings show a perfect correlation (φ = 1.0) between breakfast habits and learning concentration. All students who had breakfast exhibited high concentration, while all students who skipped breakfast demonstrated low concentration. The chi-square test yielded a value of 59, which exceeds the critical values at both 5% and 1% significance levels. These results indicate a statistically significant and strong positive relationship between breakfast consumption and mathematics learning concentration. The study concludes that breakfast is a critical external factor that enhances students’ cognitive readiness and supports academic success, particularly in mathematics.
