Abstract

Language skills have an important role for a person in carrying out daily activities or at work. Just like speaking, it is a normal human life activity and is important for being able to interact with other humans in life. This research is classroom action research (PTK) which consists of two cycles with 4 stages, namely planning, implementing actions, observing and reflecting. The data collected in this research is data regarding the learning process using the Quantum Teaching learning model and students' speaking skills obtained through observation data collection techniques, unstructured interviews and performance. Data was analyzed qualitatively and quantitatively to measure changes that occurred in students' speaking skills. The results of the research show that by applying the Quantum Teaching learning model it is possible to improve students' speaking skills in learning starting from cycle 1, the first meeting obtained results with an average score of 2.5 and at the second meeting it reached 2.51. In cycle II, the first meeting obtained results with a value of 2.56 and in the second meeting, success and improvement reached an average value of 2.85.

Abstract

   Pendahuluan: Pemfigoid bulosa (PB) merupakan penyakit vesikulobulosa autoimun yang umumnya terjadi pada populasi lansia. Beberapa obat dapat memicu reaksi autoimunitas sehingga terbentuk autoantibodi yang menyerang protein hemidesmosoal (BP180 dan BP230) pada taut dermo-epidermal. Pemberian terapi ajuvan (obat non-imunosupresif atau imunomodulator) sebagai steroid-sparing agent direkomendasi pada kasus yang tidak memberikan respon atau kurang terhadap terapi steroid. Kasus: Seorang wanita berusia 38 tahun yang mengalami bula tegang berisi cairan terutama pada area wajah, fleksural lengan, dan perut setelah mengkonsumsi ampisilin. Tanda Nikolsky dan Asboe-Hansen negatif. Gambaran dermoskopi ditemukan yellowish-pink translucent areas dengan lingkaran retikular berwarna coklat muda. Gambaran histopatologi ditemukan adanya spongiosis fokal dan celah sub-epidermal dengan infiltrasi sel-sel radang eosinofil pada perivaskular papilla dermis. Pasien didiagnosis sebagai pemfigoid bulosa yang dicurigai dicetuskan oleh ampisilin dan diberikan injeksi metil-prednisolon 50mg/24 jam (setara dosis prednisolon 1 mg/KgBB/hari), cetirizine 10mg, krim clobetasol propionate 0,05%, krim mupirocin 2%, kompres basah menggunakan NaCL 0,9%, dan tambahan hidroksiklorokuin 2x200mg (dosis 6,5 mg/KgBB/hari). Diskusi: Ampilisin merupakan salah satu obat yang dicurigai sebagai pencetus PB melalui pembentukkan neoantigen atau molecular mimicry sehingga menyebabkan disregulasi respons sel T dan menghasilkan autoantibodi terhadap protein hemidesmosomal yang terletak di BMZ. Hidroksiklorokuin memiliki efek anti-inflamasi dan imunomodulator sehingga mulai digunakan sebagai terapi ajuvan pada berbagai penyakit autoimun. Potensi hidroksiklorokuin sebagai steroid-sparing agent juga telah banyak dilaporkan, tetapi penggunaanya sebagai terapi ajuvan pada PB belum pernah dilaporkan. Kesimpulan: Penggunaan terapi ajuvan seperti hidroksiklorokuin sebagai steroid-sparing agent pada PB, dapat menghambat produksi sitokin inflamasi sehingga efektif dan aman digunakan.

Abstract

Kurikulum Merdeka hadir sebagai respons terhadap kebutuhan pendidikan yang lebih fleksibel, relevan, dan kontekstual. Penelitian ini bertujuan untuk menggambarkan implementasi Kurikulum Merdeka berdasarkan pandangan guru pada jenjang Sekolah Dasar (SD) dan Sekolah Menengah Pertama (SMP). Menggunakan pendekatan kualitatif, data diperoleh melalui wawancara dengan guru-guru dari berbagai sekolah di Sumatera Utara. Hasil menunjukkan bahwa sebagian besar guru menyambut baik Kurikulum Merdeka karena memberikan keleluasaan dalam memilih pendekatan pembelajaran. Namun, keterbatasan fasilitas, kurangnya pelatihan, dan tantangan diferensiasi siswa masih menjadi hambatan utama. Temuan ini menunjukkan perlunya dukungan pelatihan berkelanjutan dan peningkatan infrastruktur pendidikan untuk keberhasilan implementasi kurikulum.

Abstract

Gorga is a carving or sculpture typically found on the exterior of a Toba Batak traditional house. The Batak people use fractal (geometric) dimensions in Batak gorga carvings. In mathematics, repetitive and symmetrical patterns in planes that result from transformations are included in the plane symmetry groups. Ethnomathematics is a cultural approach to the concept of mathematics. A frieze group can be defined as a symmetrical group which arises from a unidirectional translation and subsequently generates a linear pattern that recurs exclusively in a single direction. There are seven different pattern types in the frieze groups. Meanwhile, crystallographic patterns are flat two-dimensional patterns that form a lattice. There are 17 crystallographic types of patterns with five different types of unit lattices. The purpose of this study is to generate motifs for Batak ornaments based on frieze groups and crystallographic groups using a Matlab Graphical User Interface (GUI). A total of 119 new motifs were generated based on seven types of patterns in the frieze groups, namely, F1,F2,F3,F4,F5,F6, and F7. Meanwhile, in the crystallographic groups, 153 new motifs were generated based on nine types of patterns, namely, p1,p2,pm,pg,cm,pmg,pmm,cmm, and pgg. To keep with trends, the new motifs generated can be used in everyday life as decorations or business symbols that are characteristic of the Toba Batak region.

Abstract

Creative thinking ability is one of the essential demands of 21st-century learning, which needs to be supported by science process skills to foster deeper understanding and meaningful learning experiences. However, science learning in schools is still largely dominated by lecture methods with minimal practical activities, resulting in students being less active, untrained in creative thinking, and rarely engaged in scientific processes. This study aims to investigate the effect of the Project-Based Learning (PjBL) model with a STEM (Science, Technology, Engineering, and Mathematics) approach on students’ creative thinking ability and science process skills in the topic of elements, compounds, and mixtures. The research employed a quasi-experimental method with a pretest-posttest control group design for creative thinking ability and a posttest-only control group design for science process skills. The sample consisted of two eighth-grade classes selected through random sampling, with 30 students in each class. One class was assigned as the experimental group, taught using the STEM-based PjBL model, while the other served as the control group using conventional instruction. Research instruments included essay tests and observation sheets. Data analysis using the t-test revealed a significant effect on creative thinking ability (p = 0.001, p < 0.05) and science process skills (p = 0.004, p < 0.05). The novelty of this study lies in the integration between the design of PjBL and the STEM approach, with systematic measurement of two important indicators of 21st-century learning: creative thinking and science process skills, in the context of applied basic chemistry topics. Thus, the findings affirm that integrating PjBL with STEM is effective in fostering 21st-century skills. Based on these results, it is recommended that innovative and contextually relevant projects be designed to support the development of meaningful science learning.
