Abstract

Continuous Professional Development includes three things, namely self-development, scientific publications, and innovative work. The problems that occur in partners are still a lack of understanding of mathematics teachers about making scientific articles and still a lack of understanding about the stages of publication of scientific articles in journals through OJS. To facilitate scientific publications of mathematics teachers, Tidar University organizes assistance in writing scientific articles and scientific publications as a means of teacher self-development, especially teachers who are members of the mathematics MGMP of SMP Temanggung Regency. The methods used are socialization (discussion and question and answer), assistance in article preparation, practical exercises in using the open journal system (OJS), and evaluation. At the end of the activity, a survey will be conducted to check the understanding of partners after the activity. The implementation of this Community Partnership Program activity was carried out as many as 2 meetings in the Hall of SMP Negeri 2 Temanggung offline and online using gmeet. Service activities include training, mentoring, and socialization of manuscript submissions to destination journals. The result of the service activities is that junior high school mathematics teachers throughout Temanggung Regency get a good understanding in writing scientific articles and publishing articles in the field of mathematics education

Abstract

The debt instrument (bond) as one of the investment instruments in the Capital Market has a main risk known as default. Default risk can be mitigated if investors assess the credit quality of the bond and its issuer, as measured by rating. In this research, the initial rating of issuers was investment grade (BBB or higher) and valid for at least 1 year, with their business operations based in Indonesia. The observation period was from 2007 to 2023. A Markov Chain was used to create a transition matrix to analyze transitions and default. The probability of AAA staying over 1 year is 0.9858 whereas the likelihood of AA, A, and BBB staying in the same rating is 0.9203, 0.8825, and 0.8630, respectively. The BBB in a 5-year transition has the highest probability of default by 0.0370. The Euclidean distance was used to measure the similarity of default durations. The 1-year and 3-year transition have the shortest distance, at  0.00939. The conclusion of this research is a higher rating has a higher probability of staying at the same rating and carries lower risk. Furthermore, 1-year and 3-year transitions show similarities based on their probability of default.

Abstract

Mathematical literacy is an essential competency that enables students to apply mathematical knowledge to solve real-world problems. However, students' mathematical literacy achievement remains relatively low, indicating the need for more effective instructional approaches. This study aimed to examine the effectiveness of the Contextual Teaching and Learning (CTL) model on students' mathematical literacy across different levels of learning motivation in trigonometry. A quantitative approach was adopted, using a quasi-experimental, nonequivalent posttest-only control group design. An initial mathematical ability test was administered solely to examine baseline equivalence between the groups before the intervention. The participants were 47 eleventh-grade students of SMA Mutual Magelang, consisting of an experimental class taught using the CTL model and a control class taught through direct instruction over four 90-minute instructional meetings. Data were collected using a mathematical literacy test and a learning motivation questionnaire and were analyzed using a two-way ANOVA with unequal cell frequencies. The results revealed significant effects of the learning model (F = 4.762,p < 0.05) and learning motivation (F = 26.217,p < 0.05) on students' mathematical literacy. However, no statistically significant interaction effect was found between the learning model and learning motivation (F = 0.061,p > 0.05). Students taught using the CTL model achieved higher mathematical literacy scores than those taught through direct instruction. These findings suggest that the CTL model is effective in improving students' mathematical literacy and that learning motivation is associated with differences in mathematical literacy achievement under the conditions of the present study.

Abstract

Traditional folk songs can function as cultural texts through which communities communicate and preserve moral and social values. This study examines how evaluative linguistic resources construct moral meanings in the Javanese folk song "Gundul-Gundul Pacul." Using a qualitative text-analysis approach, the study applies Systemic Functional Linguistics (SFL) and the Appraisal framework to analyze the song's lyrics in terms of Attitude, Engagement, and Graduation, as well as ideational, interpersonal, and textual meanings. The findings show that the lyrics construct negative evaluations of arrogant and irresponsible behavior and represent the consequences of inappropriate leadership. Judgment is particularly evident in the evaluation of arrogant behavior, while Appreciation contributes to the representation of negative outcomes. The lyrics predominantly present evaluation directly, and repetition functions to strengthen the force and prominence of the moral message. These evaluative resources construct broader meanings related to leadership, responsibility, humility, and the consequences of arrogance. The study demonstrates that Appraisal Theory combined with an SFL perspective can provide a systematic linguistic account of how moral and cultural meanings are constructed in traditional folk songs.

Abstract

Kualitas pengajaran bahasa Inggris di jenjang Sekolah Menengah Pertama (SMP/MTs) di Kabupaten Magelang masih menghadapi tantangan, terutama dalam penerapan metode yang mendorong keterlibatan siswa secara aktif sesuai dengan Kurikulum Merdeka. Program pengabdian masyarakat ini bertujuan untuk memperkuat kapasitas guru bahasa Inggris melalui penerapan pendekatan pembelajaran mendalam dan pengajaran interaktif. Program ini dilaksanakan bekerja sama dengan MGMP Bahasa Inggris dan melibatkan serangkaian lokakarya berjenjang—pengenalan konsep, praktik merancang strategi interaktif, pengembangan media pembelajaran yang menyenangkan, dan pendampingan penyusunan rencana pembelajaran (RPP). Sebanyak 49 guru bahasa Inggris berpartisipasi aktif dalam program ini. Hasilnya menunjukkan peningkatan yang signifikan dalam pemahaman guru tentang prinsip-prinsip pembelajaran mendalam, kemampuan mereka merancang media pembelajaran kreatif tingkat A1, dan kompetensi mereka dalam menghasilkan rencana pembelajaran inovatif yang selaras dengan praktik pengajaran interaktif. Hasil ini menyoroti efektivitas pendampingan berbasis praktik dan lokakarya kolaboratif dalam meningkatkan kapasitas pedagogis. Studi ini menyimpulkan bahwa dukungan sistematis dan kolaborasi berkelanjutan sangat penting untuk mendorong pembelajaran bahasa Inggris yang inovatif dan berpusat pada siswa di sekolah menengah.
