Abstract

Menerapkan pembelajaran berorientasi higher order thiking skills (HOTS) dengan model PBL. Keterampilan berpikir kritis dapat diimplementasikan dengan pembelajaran berbasis HOTS (High Order Thinking Skill). Pembelajaran berbasis HOTS dapat dijadikan sebagai alternatif untuk menghadapi tuntutan abad ke 21. Tujuan penerapan PBL adalah kemampuan siswa untuk berpikir kritis, analisis, sistematis serta logis untuk menemukan alternatif solusi atas masalah melalui eksplorasi data secara empiris dalam rangka menumbuhkan sikap ilmiah pada siswa. Dengan demikian penerapan PBL dalam pembelajaran matematika memiliki peran yang penting dalam meningkatkan kemampuan matematis. Oleh karena itu tujuan dari penulisan kajian ini adalah untuk memaparkan kaitan antara HOTS dalam pembelajaran matematika dengan model pembelajaran problem based learning. Pemahaman dan kesadaran akan pentingnya HOTS akan membuat siswa termotivasi untuk mengikuti pembelajaran dan dengan model pembelajaran problem based learning dapat meningkatkan kemampuan pemecahan masalah matematika di sekolah dasar.

Abstract

The research "Effectiveness of Mom's Bra-Tem Compress for Postpartum Mothers with Breast Engorgement" is a government program aimed at addressing breast engorgement. Demographic data in Indonesia (SDKI) indicates that in 2012-2013, 55% of breastfeeding mothers suffered from breast engorgement and mastitis, caused by inadequate breast care. Breast engorgement often occurs during lactation. If oxytocin release is not smooth, breast milk secretion is inhibited, leading to swelling of the mammary glands and causing discomfort. Therefore, immediate and continuous intervention is needed in midwifery care for postpartum mothers with breast engorgement. The purpose of the Mom's Bra-Tem Compress, a bra filled with jelly, is to reduce breast engorgement in a simple, comfortable, efficient, and effective way that can be used anywhere and anytime. The method used is quasi-experimental with a pretest-posttest control group design. The research subjects are postpartum mothers with breast engorgement. The sampling technique used is random sampling. The instrument used to assess the level of engorgement is the Six Point Engorgement Scale (SPES). Data analysis was conducted using univariate and bivariate analysis with Wilcoxon signed-rank test and Mann-Whitney test. The results showed that the use of Mom’s Bra-Tem Compress had an impact on postpartum mothers.

Pengambilan sampel dilakukan berdasar atas Consecutive Sampling. Penelitian dilaksanakan pada bulan April 2024. Hasil pengukuran jumlah darah dan besar kontraksi dianalisis menggunakan Independent T Test. Hasil penelitian menununjukkan bahwa rerata jumlah darah yang dikeluarkan pada kala IV di kelompok intervensi yaitu 125,33 ml±16,554 ml dan kelompok kontrol 175,67±17,943mL. Besarnya kontraksi pada kelompok intervensi 55,07 mmHg ± 4,425mmHg sedangkan kelompok kontrol 52,0 mmHg± 6,744 mmHg (p=0,044). Hasil penelitian menunjukan bahwa sand suck lebih efektif dalam pencegahan terjadinya atonia uteri dibanding dengan menggunakan Standard Operating Procedure (SOP).

Abstract

Digital transformation in human resource management (HR) is a challenge as well as an opportunity for MSMEs in an effort to realize business sustainability. This research aims to explore how the digital adaptation process is carried out in MSME HR management practices, as well as identify the challenges faced in its implementation. Using a qualitative approach through in-depth interviews with MSME actors in the creative sector, the data was analyzed thematically to reveal the patterns and dynamics of digital transformation. The results of the study show that most MSMEs have adopted simple technology such as WhatsApp, Google Form, and video tutorials in the process of recruitment, training, and performance recording. However, the limitations of digital literacy of the workforce and infrastructure are the main obstacles. These findings indicate that the digitization of human resources in MSMEs is still gradual and adaptive, and is highly dependent on individual readiness and external support. In conclusion, digital transformation in MSME human resources not only requires technology, but also strengthens human resource capacity and work culture that is inclusive of change. The implications of this study encourage the existence of digital literacy mentoring programs and collaborative policies between business actors, the government, and educational institutions to strengthen the competitiveness of MSMEs in a sustainable manner.

Abstract

This study aims to map the evolution of literature related to planning and forecasting within the context of accounting management using a bibliometric approach. Employing a Systematic Literature Review (SLR) and bibliometric analysis based on data retrieved from the Scopus database between 1973 and 2025, the research identifies trends, knowledge structures, and both established and emerging themes in the field. A total of 55 relevant documents were analyzed using VOSviewer software through co-occurrence analysis, density visualization, and overlay visualization techniques. The findings reveal two major categories in the literature: well-established themes such as "management", "system", and "planning", and emerging topics including "management accounting course", "sustainability", and "reporting practice". These results suggest a shift in research focus toward sustainability integration, digital transformation, and innovation in accounting education curricula. This study contributes both theoretically and practically to the development of more adaptive, data-driven management accounting systems and provides valuable insights for advancing business and management education curricula.
