Abstract

Literasi digital merupakan keterampilan penting di era Revolusi Industri 4.0, khususnya bagi lulusan SMK yang disiapkan untuk segera berkarier di dunia industri. Kegiatan pengabdian ini bertujuan untuk meningkatkan kompetensi literasi digital siswa SMK Citra Bangsa Mandiri melalui pendekatan sains data. Metode pelatihan dirancang dalam enam sesi interaktif yang mengintegrasikan praktik pengolahan data, visualisasi, serta pengenalan etika digital. Hasil evaluasi berbasis pre-test dan post-test menunjukkan kenaikan skor rata-rata dari 52,5 ke 80,6, dengan nilai gain 0,591 yang tergolong kategori sedang. Hasil angket kepuasan menunjukkan keterlibatan dan pemahaman yang meningkat secara signifikan. Kesimpulan menunjukkan bahwa pelatihan berbasis sains data mampu memperkuat dimensi teknis dan etis dari literasi digital serta mendorong siswa untuk berpikir kritis dan berbasis data. Program ini direkomendasikan untuk diintegrasikan ke dalam pembelajaran reguler SMK.

Abstract

Performance not only a source of pride for students, but also for schools. The Indonesian Student Research Olympiad (OPSI) is a national-level activity recognized by the National Achievement Center (PUSPRESNAS). Schools need to provide guidance to support their students in participating in OPSI competitions, one of which is in mathematics. The purpose of this community service is to provide new learning experiences to students at SMA Negeri 1 Mirit, Kebumen Regency, in managing real-world problems and using mathematics to find solutions. Examples given are the problem of medication timing and radioactive decay. The community service method consists of material presentation, class discussions, and providing examples of problems that can be solved using similar methods. The community service is carried out once for 2 hours, the results of the community service are measured by a questionnaire, and of the 20 students who participated in the activity, all agreed that this community service provided a new learning experience that was different from the learning experience during the lessons.

Abstract

Meta-analysis is a statistical method for synthesizing quantitative data from multiple related studies, yet heterogeneity among studies often complicates interpretation. Meta-regression extends this approach by incorporating study-level covariates to explain variations in outcomes. With the global increase in depression, Acceptance and Commitment Therapy(ACT) has attracted attention as an effective psychological intervention. Therefore, a deeper understanding of the factors that influence its effectiveness across studies is needed. However, to date, only a few meta-analyses have quantitatively examined moderator variables that influence ACT outcomes using a random effects meta-regression approach. This study aims to fill this gap. This study estimated the model parameters using the Weighted Least Squares (WLS) method. Thirty-three published studies testing the effectiveness of ACT in reducing depression were collected from PubMed, Google Scholar, and Science Direct. The homogeneity test results showed significant heterogeneity, supporting the use of a random effects model. The combined effect size of -0.321 indicates that ACT significantly reduces depression levels compared to the control group. Meta-regression analysis revealed that variation in effect size was significantly influenced by differences in the average age of patients and duration of therapy. These findings provide new insights into the conditions and characteristics that make ACT therapy more effective.

Abstract

Belajar matematika menjadi momok tersendiri bagi siswa. Untuk itu diperlukan suatu metode supaya pembelajaran matematika menjadi sesuatu yang menyenangkan bagi siswa sehingga kedepannya kesan sulit pada pelajaran matematika dapat dihapus. Salah satu cara yang dapat dilakukan adalah dengan mengajak mereka belajar matematika sambil bermain. KARTIKA (Kartu Matematika) dirancang sebagai salah satu media pembelajaran matematika yang dikemas melalui permainan edukatif. Sasaran dari KARTIKA adalah siswa sekolah dasar kelas 4 dan 5. Permainan ini diterapkan pada siswa SD Islam Pangeran Diponegoro. KARTIKA adalah mainan kartu layaknya kartu bridge (kartu remi), perbedaan KARTIKA dengan kartu bridge adalah cara penomoran kartunya. Dalam KARTIKA setiap kartu berisikan operasi hitung yang disesuaikan dengan materi pembelajaran siswa sekolah dasar. Dimana jawaban dari operasi hitung itu adalah angka 1 sampai dengan 13. Sehingga untuk bisa bermain, siswa dituntut untuk bisa menyelesaikan operasi hitung yang ada di dalam kartu. Metode ini cukup efektif untuk mengajak anak belajar matematika. Karena pada pembelajaran matematika dengan media KARTIKA, anak menganggap dirinya sedang bermain, namun pikiran mereka tetap dijalankan untuk memecahkan operasi hitung yang ada pada kartu.
