Abstract

XYZ merupakan salah satu instansi yang menangani pendistribusian darah dengan jumlah pasokan yang dibutuhkan untuk memenuhi permintaan bersifat tidak pasti. Permasalahan terjadi pada manajemen persediaan yang berdampak pada fluktuasi stok darah. Penelitian ini dilakukan menggunakan pendekatan sistem dinamik untuk merancang model persediaan darah pada XYZ serta memberikan rekomendasi skenario terbaik terhadap permasalahan ada berdasarkan prioritas indikator tujuan. Struktur model digambarkan dalam causal loop diagram dan stock and flow diagram. Fungsi tujuan model pemodelan ini adalah meminimumkan ketidakstabilan terhadap persediaan darah sehingga dapat menstabilkan antara pemasukan dan pengeluaran donor darah. Empat skenario kebijakan yang disimulasikan pada model dengan parameter yang digunakan adalah jumlah donor pengganti dan darah kadaluwarsa yang rendah. Hasil simulasi skenario yang terbaik adalah skenario yang memiliki jumlah donor sebanyak 230 kantong setiap 15 hari dengan kebijakan pengadaan donor dua kali dalam satu bulan.

Abstract

Pada era Revolusi Industri 4.0 perkembangan informasi dan teknologi telah merubah wajah dunia. Salah satunya dunia pendidikan, dimana pendidik harus melek teknologi untuk meningkatkan pembelajaran. Tujuan artikel untuk menelaah lebih mendalam mengenai Teknological Pedagogical Content Knowledge (TPACK).TPACK merupakan sebuah kerangka kerja pembelajaran yang mengintegrasikan pengetahuan konten, pedagogi, dan teknologi dalam pembelajaran tertentu. Kerangka kerja ini penting untuk mengembangkan kompetensi pendidik pada pembelajaran abad 21. Metode menggunakan kajian pustaka, yaitu menelaah 5 jurnal nasional selanjutnya di analisis menggunakan teknik analisis isi. Hasil kajian terkait TPACK yaitu: 1) Merupakan jenis pengetahuan yang baru untuk pendidik; 2) Merupakan kerangka kerja dengan mengintegrasikan pengeatahuan konten, pedagogi dan teknologi; 3) Memberikan keuntungan bagi pendidik; 4) Pendidik dapat mengetahui tingkat pengetahuan peserta pendidik; 5) pendidik mengetahui lima kriteria untuk merancang pembelajaran berbantuan teknologi, Jadi TPACK dapat digunakan pendidik abad 21 untuk dijadikan kerangka pembelajaran yang efektif dan menarik.

Abstract

This study aims to analyze the supporting factors and challenges that influence student engagement in English learning among first graders at SDN 01 Kalisari. The research focuses on how teacher strategies, classroom interactions, and students’ emotional conditions contribute to their involvement in the learning process. A descriptive qualitative method was applied, using non-participant observation with multiple observers, supported by interviews with the subject teacher. The findings of this study indicate that students’ level of engagement varied across different indicators. Teacher–student interaction and activity variation received the highest scores, with 83.3% categorized as very good, whereas the teacher’s activeness in moving around the classroom obtained the lowest score, at 33.3% (low category). Several factors were identified as supporting engagement, including active teacher–student interaction, the use of diverse instructional media, the implementation of kinesthetic activities, the provision of verbal praise, as well as the incorporation of ice breaking activities, games, and songs that enhanced students’ enthusiasm. On the other hand, the main challenges observed were uneven learning motivation among students, limited instructional time in large classes, and the insufficient habituation of using English outside the classroom.. These findings highlight that young learners’ engagement in foreign language learning is shaped by a combination of pedagogical, emotional, and environmental factors. The study implies that developing creative and humanistic teaching strategies, as well as expanding opportunities for English use both inside and outside the classroom, is essential for sustaining student engagement

Abstract

XYZ is one of the agencies that handle the distribution of blood with the amount of supply needed to meetdemand is uncertain. Problems occur in inventory management which has an impact on bloodstockfluctuations. This research was conducted using a dynamic system approach to design a blood supplymodel at XYZ and provide recommendations for the best scenario for existing problems based on thepriority indicators of the objectives. The structure of the model is described in causal loop diagrams andstock and flow diagrams. The objective function of this modeling model is to minimize the instability ofthe blood supply so that it can stabilize the intake and output of blood donors. Four policy scenarios aresimulated in the model with the parameters used is the number of replacement donors and low expiredblood. The simulation result for the best scenario is a scenario that has 230 donor bags every 15 days witha policy of procuring donors twice in one month.
